Description
CROSS-REFERENCES TO RELATED APPLICATIONS
[0001] The present application claims priority under 35 U.S.C.
.sctn.119 to Japanese Patent Application No. 2000-251420,filed on
Aug. 22, 2000, entitled "FASTENING MEMBER AND SIDING BOARDS
ATTACHMENT STRUCTURE". The contents of this application are
incorporated herein by reference in their entirety.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates to a fastening member that is
disposed at an upper rabbeted horizontal edge and a lower rabbeted
horizontal edge of a siding board for mounting the siding board to
a framework with an underlayment being interposed between, a siding
boards attachment structure employing the same, a starter member
(that is a starter) that is disposed at a lowermost end of the
siding boards attachment structure, and further relates to a method
of attaching siding boards.
[0004] 2. Discussion of the Background
[0005] Conventionally, there exists a siding boards attachment
structure 90 as shown in FIGS. 18 to 21 in which a plurality of
siding boards 2 are fixed to a framework with an underlayment 8
being interposed between by using a fastening member 9 (FIG.
17).
[0006] In such a siding boards attachment structure 90, the
fastening member 9 is disposed to bridge over a joint portion of
upper and lower siding boards 2, that is, a portion between an
upper rabbeted horizontal edge 21 and a lower rabbeted horizontal
edge 22 of the siding boards 2 as illustrated in FIGS. 19 and 21 so
as to mount the siding boards 2 to the framework with the
underlayment 8 being interposed between.
[0007] It should be noted that a furring strip is illustrated in
FIGS. 18 to 21 as the underlayment 8.
[0008] As illustrated in FIGS. 17 to 21, the fastening member 9
includes a base plate portion 91 abutting on rear side surfaces 26
of siding boards 2 that are vertically disposed, a support portion
92 that is provided to erect frontward from the base plate portion
91, an upper board engaging portion 93 that is bent in an oblique
upward direction from the support portion 92, and a lower board
engaging portion 94 that is bent in an oblique downward direction
from the support portion 92. A front flat plate portion 934
abutting on a rear surface of an overlying tongue portion 226 of a
lower overlying tongue portion of the upper siding board 2 is
formed in front of the upper board engaging portion 93 and the
lower board engaging portion 94.
[0009] The base plate portion 91 includes a nail hole 98 and a
screw hole 99 for inserting therein a nail 41 and a screw 42,
respectively, for fixing the fastening member 9 to the framework
with the underlayment 8 being interposed between.
[0010] As illustrated in FIG. 17, the base plate portion 91
includes a sloped portion 911 at an upper portion thereof that is
curved in an oblique rearward direction and further a lower leg
portion 912 at a lower end portion thereof that is bent rearward at
an angle of approximately 90.degree.. A central plate portion 913
is provided between the sloped portion 911 and the lower leg
portion 912 for connecting these members and further abutting on
the rear side surfaces 26 of the siding boards 2. The support
portion 92 is erected from the central plate portion 913.
[0011] The nail hole 98 is formed on the sloped portion 911 and the
screw hole 99 is provided on the central plate portion 913 formed
between the sloped portion 911 and the support portion 92.
[0012] When the fastening member 9 is fixed to the framework with
the underlayment 8 being interposed between, the fastening member 9
is fixed to the framework with the underlayment 8 being interposed
between by the nail 41 or the screw 42. More particularly, when
using the nail 41, the fastening member 9 is fixed to the framework
by piercing the nail 41 through the nail hole 98 and driving the
nail 41 to the framework with the underlayment 8 being interposed
between in an oblique downward direction, as illustrated in FIGS.
18 and 19.
[0013] When using the screw 42, the screw 42 is pierced through the
screw hole 99 and screwed into the framework with underlayment 8
being interposed between for fixing the fastening member 9 to the
framework with the underlayment 8 being interposed between as
illustrated in FIGS. 20 and 21.
[0014] In this manner, the fastening member 9 is arranged so that a
person performing the construction may freely select either fixing
using a nail 41 (FIGS. 18 and 19) or fixing using a screw 42 (FIGS.
20 and 21) depending on various conditions at the time of
performing construction.
[0015] However, such a fastening member 9 exhibits the following
drawback.
[0016] The closer the nail 41 or the screw 42 is disposed to the
support portion 92 that receives the load, the larger fixing force
of the fastening member 9 to the framework against load of the
siding board 2 or wind pressure is.
[0017] Thus, in case of that the nail hole 98 and the screw hole 99
are disposed at positions at which a distance from the nail hole 98
to the support portion 92 and a distance from the screw hole 99 to
the support portion 92 are different, the fixing force against load
or wind pressure will differ between fixing by the nail 41 and
fixing by the screw 42.
[0018] In the fastening member 9, the nail hole 98 is formed on the
sloped portion 911 while the screw hole 99 is formed on the central
plate portion 913, respectively (FIG. 17). That is, the nail hole
98 is remoter from the support portion 92 than the screw hole 99.
Thus, the fixing force when fixing is performed by the nail 41
(FIGS. 18 and 19) will be smaller than the fixing force when fixing
is performed by the screw 42 (FIGS. 20 and 21).
[0019] In the siding boards attachment structure 90 employing the
fastening member 9, there is a difference in fastening forces of
the siding board 2 to the framework between using the nail 41 and
using the screw 42. Consequently, performances such as wind
pressure-resistance and others will vary depending on means for
fixing the fastening member 9.
[0020] In order to prevent producing partial differences in
fastening force of siding boards in a single building, it will be
necessary to unify the fixing means for performing construction,
either the nail 41 or the screw 42. Further it is not preferable
that differences in fastening forces of siding boards exist between
each building. It will therefore be necessary to unify the fixing
means for performing construction when a plurality of buildings are
built.
SUMMARY OF THE INVENTION
[0021] An object of the present invention is to provide a fastening
member which causes hardly any differences in fastening force of
siding boards owing to differences in means for fixing the fittings
to a building frame, an exterior wall construction structure using
the same, a starter member, and further a method of attaching
siding boards.
[0022] According to one aspect of the invention, a fastening member
is disposed to bridge over an upper rabbeted horizontal edge of a
lower siding board and a lower rabbeted horizontal edge of an upper
siding board for mounting the siding boards to a framework of a
building with an underlayment being interposed between,
[0023] wherein the fastening member includes a base plate portion
abutting on rear side surfaces of siding boards that are vertically
disposed, a support portion that is provided to erect frontward
from the base plate portion, an upper board engaging portion that
is bent in an oblique upward direction from the support portion,
and a lower board engaging portion that is bent in an oblique
downward direction from the support portion,
[0024] wherein the base plate portion includes a nail hole and a
screw hole through which a nail and a screw are respectively
pierced for fixing the fastening member to the framework, and
[0025] wherein the nail hole and the screw hole are provided at
position at which a distance from the nail hole to the support
portion and a distance from the screw hole to the support portion
are substantially equal.
[0026] It is a notable point of the present invention that the nail
hole and the screw hole are provided at position at which a
distance from the nail hole to the support portion and a distance
from the screw hole to the support portion are substantially equal.
That is, a vertical distance A from a central plane of the support
portion to the nail hole and a vertical distance B from the central
plane of the support portion to the screw hole are substantially
equal (see FIG. 2(B)).
[0027] It should be noted that the following explanations will be
made supposing that a side of the fastening member itself on which
the nail hole is formed is the "upper" side and the opposite side
is the "lower" side, when viewed from the support portion, for
defining respective names of portions.
[0028] The screw hole is formed on the side which is opposite to
the nail hole. That is, since the screw hole is provided downward
of the support portion, the direction of the fastening member needs
to be turned upside down when performing fixing using the screw. In
this case, the upper board engaging portion will engage the lower
siding board and the lower board engaging portion will engage the
upper siding board (see FIG. 6).
[0029] With this arrangement, the positional relationship of the
nail and the screw from the support portion will be substantially
identical with no matter which the nail or the screw is used.
[0030] Working effects of the present invention will now be
explained.
[0031] As explained above, the nail hole and the screw hole are
disposed in the above fastening member at positions at which
distances between the holes and the support portion are
substantially equal. Thus, there is almost no differences in fixing
force against load of the upper siding board or wind pressure
between fixing the fastening member by the nail and fixing the
fastening member by the screw.
[0032] There is almost no differences in fastening force of siding
boards between fixing the fastening member by the nail and fixing
the fastening member by the screw when arranging the exterior wall
construction structure. That is, no drawbacks such as isolation or
falling off of siding boards are caused by changing means for
fixing the fastening member. For instance, performances such as
wind pressure-resistance of siding boards attachment structures
will not vary depending on means for fixing the fastening
member.
[0033] The fastening member is further advantaged in that easy
construction is enabled since a person performing the construction
may freely select the fixing means, either nails or screws, in
accordance with various conditions at the time of
constructions.
[0034] As explained so far, it is possible to provide a fastening
member with which hardly any differences in fastening force of
siding boards are caused owing to differences in means for fixing
the fastening member to the framework.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0059] The preferred embodiments will now be described with
reference to the accompanying drawings, wherein like reference
numerals designate corresponding or identical elements throughout
the various drawings.
[0060] It is preferable that the base plate portion includes an
upper abutting portion and a lower abutting portion that abut the
underlayment at its upper and lower portion, an upper rising
portion and a lower rising portion that are respectively formed in
a frontward rising manner from the upper abutting portion and the
lower abutting portion, and a central plate portion being installed
to connect the upper rising portion and the lower rising portion
and abutting against the rear side surfaces of the siding boards,
wherein the support portion is formed to be erected from the
central plate portion.
[0061] With this arrangement, the siding boards may be mounted to
the framework with a clearance formed between the rear side
surfaces of the siding boards and the underlayments. A ventilation
layer will be accordingly formed between the siding boards and the
underlayments for improving the durability of the siding boards
attachment structure.
[0062] It is further preferable that the upper rising portion and
the lower rising portion include a horizontal plane portion that is
arranged to form a substantially right angle with respect to the
central plate portion.
[0063] With this arrangement, it is possible to obtain a fastening
member which is easy to be constructed.
[0064] For fixing the fastening member to the framework, the
fastening member is first engaged at the lower siding board. More
particularly, the upper rabbeted horizontal edge of the lower
exterior wall plate is inserted into space formed by the central
plate portion, the support portion and the lower board engaging
portion of the fastening member.
[0065] By engaging the lower board engaging portion at the upper
rabbeted horizontal edge of the siding board and hitting the
fastening member from above by a hammer or the like, the upper
rabbeted horizontal edge of the siding board and the fastening
member are fitted.
[0066] As described above, since the fastening member includes the
horizontal plane portion in the upper rising portion and the lower
rising portion thereof, the horizontal plane portion may be hit
from above. With this arrangement, the fastening member may be
easily and reliably fitted to the siding board.
[0067] In case of that the fastening member is used with the nail
hole being positioned above the support portion, the fastening
member is fitted to the siding board by hitting the horizontal
plane portion formed in the upper rising portion. On the other
hand, in case of that the fastening member is used with the screw
hole being positioned above the support portion, the fastening
member is fitted to the siding board by hitting the horizontal
plane portion formed in the lower rising portion.
[0068] It is preferable that the fastening member includes
protruding portions projecting frontward from an upper end of the
upper abutting portion and from a lower end of the lower abutting
portion (see FIG. 12).
[0069] With this arrangement, similarly, the fastening member may
be easily and reliably fitted to the siding board by hitting the
protruding portion.
[0070] It is further preferable that the upper rising portion
includes a sloped portion wherein the nail hole is formed on the
sloped portion.
[0071] With this arrangement, the nail may be pierced through the
nail hole and be driven to the framework with the underlayment
being interposed between in an oblique downward direction. Thus,
the fastening member may be reliably fixed to the framework and
reliably engaged at the lower siding board.
[0072] It is preferable that the upper abutting portion and the
lower abutting portion include an abutting surface that is
substantially horizontal to the central plate portion (see FIGS. 1
and 11).
[0073] With this arrangement, a contact surface of the upper
abutting portion and the lower abutting portion with the
underlayment may be large, and it is possible to prevent the upper
abutting portion and the lower abutting portion from being buried
into the underlayment. More particularly, also in case of that the
underlayment is a soft material such as a foamed plastic resin
board, the upper abutting portion and the lower abutting portion of
the fastening member will not be buried into the underlayment, and
it is possible to prevent the fastening member from sinking into
the underlayment.
[0074] Thus, the siding boards may be stably fastened to the
framework with the underlayment being interposed between.
[0075] It is preferable that the fastening member is of a shape
that is elongated in lateral directions such that a plurality of
studs of the framework that are disposed in a laterally aligned
manner maybe connected and fixed (see FIGS. 14 and 15).
[0076] With this arrangement, laterally arranged siding boards may
be reliably mounted to the framework also in case of that left
rabbeted vertical edges or right rabbeted vertical edges of the
siding boards are not disposed on the studs of the framework.
[0077] More particularly, in case of that such a fastening member
is employed for a siding boards attachment structure using a wood
frame construction, it is necessary to dispose the fastening member
at a portion at which a stud is provided for securing strength. On
the other hand, the fastening member needs to be disposed on the
upper rabbeted horizontal edge and the lower rabbeted horizontal
edge on a corner portion of the siding board.
[0078] At this time, in case of that the left rabbeted vertical
edge or the right rabbeted vertical edge of the siding board is not
disposed on the stud, that is, in case of that the corner portion
of the siding board is not disposed on the portion where a stud is
present, the fastening member may not be disposed on a portion
where the stud is present and the corner portion of the siding
board is located in case of that the fastening member is short.
[0079] Thus, by arranging the fastening member to be a shape that
is elongated in lateral directions for enabling connection and
fixing of a plurality of studs, it will be possible to arrange a
siding boards attachment structure exhibiting satisfactory
strength.
[0080] According to another aspect of the invention, a siding
boards attachment structure includes a fastening member being
disposed on an upper rabbeted horizontal edge and a lower rabbeted
horizontal edge of a siding board for mounting the siding board to
a framework of a building with an underlayment being interposed
between,
[0081] wherein the fastening member includes a base plate portion
abutting against rear side surfaces of siding boards that are
vertically disposed, a support portion that is provided to erect
frontward from the base plate portion, an upper board engaging
portion that is bent in an oblique upward direction from a front
end portion of the support portion, and a lower board engaging
portion that is bent in an oblique downward direction from the
support portion,
[0082] wherein the base plate portion includes a nail hole and a
screw hole through which a nail and a screw for fixing the
fastening member to the framework are pierced and that are disposed
at positions at which a distance from the nail hole to the support
portion and a distance from the screw hole to the support portion
become substantially equal,
[0083] wherein the fastening member is arranged such that the nail
hole is disposed upward of the support portion with the nail being
fixed while being pierced through the nail hole in case of that the
fastening member is fixed to the framework by the nail, and
[0084] wherein the fastening member is arranged such that the screw
hole is disposed upward of the support portion with the screw being
fixed while being pierced through the screw hole in case of that
the fastening member is fixed to the framework by the screw.
[0085] The screw hole of the above fastening member is formed
downward of the support portion. Thus, when performing fixing by
the screw, the direction of the fastening member is turned upside
down. In this case, the upper board engaging portion will engage
the lower siding board while the lower board engaging portion will
engage the upper siding board (see FIG. 6).
[0086] In the siding boards attachment structure, the distances
from the support portion to the nail and to the screw are
substantially equal, in the cases of that fastening member is fixed
by the nail and that the fastening member is fixed by the
screw.
[0087] Thus, hardly any differences in fixing force are caused in
case the fastening member is fitted by the nail and by the screw.
In other word, hardly any differences in fastening force of siding
boards will be caused depending on means for fixing the fastening
member.
[0088] Thus, it is possible to provide a siding boards attachment
structure with hardly any differences in fastening force of siding
boards being caused depending on means for fixing to the
framework.
[0089] It is preferable that the base plate portion of the
fastening member includes an upper abutting portion and a lower
abutting portion that abut the underlayment at its upper and lower
portion, an upper rising portion and a lower rising portion that
are respectively formed in a frontward rising manner from the upper
abutting portion and the lower abutting portion, and a central
plate portion for connecting between the upper rising portion and
the lower rising portion and further abutting against the rear side
surfaces of the siding boards, wherein the support portion is
formed to erect from the central plate portion.
[0090] With this arrangement, a ventilation layer will be formed
between the siding boards and the underlayments for improving the
durability of the siding boards attachment structure.
[0091] It is further preferable that the upper rising portion and
the lower rising portion include a horizontal plane portion that is
arranged to form a substantially right angle with respect to the
central plate portion.
[0092] As described above, by hitting the horizontal plane portion
when fitting the fastening member to the upper rabbeted horizontal
edge of the siding board at the time of construction, fitting may
be easily and reliably performed. It is thus possible to obtain a
fastening member enabling easy construction.
[0093] It is preferable that the fastening member includes a
protruding portion projecting frontward from an upper end of the
upper abutting portion and from a lower end of the lower abutting
portion.
[0094] With this arrangement, the fastening member may be similarly
fitted to the siding board in an easy and reliable manner by
hitting the protruding portion.
[0095] It is further preferable that the upper rising portion
includes a sloped portion wherein the nail hole is formed on the
sloped portion.
[0096] With this arrangement, pressurizing force of the nail that
is directed in an oblique downward direction with respect to the
framework will act on the fastening member when using the nail. It
is thus possible to obtain a siding boards attachment structure in
which the fastening member is reliably fixed to the framework and
in which it is reliably engaged at the lower siding board.
[0097] It is preferable that the upper abutting portion and the
lower abutting portion include an abutting surface that is
substantially horizontal to the central plate portion.
[0098] With this arrangement, it is possible to prevent the upper
abutting portion and the lower abutting portion from cutting into
the underlayment, and to prevent the fastening member from sinking
into the underlayment.
[0099] It is thus possible to obtain a siding boards attachment
structure in which siding boards are stably fastened to the
framework with the underlayment being interposed between.
[0100] It is preferable that the fastening member is fixed to
connect a plurality of studs of the framework that are disposed to
be laterally aligned such that two adjoining siding boards are
engaged by a single fastening member.
[0101] With this arrangement, it is possible to obtain a siding
boards attachment structure exhibiting satisfactory strength also
in case a left rabbeted vertical edge or a right rabbeted vertical
edge of the siding board is not disposed on the stud of the
framework.
[0102] The siding boards attachment structure is preferably a
constructing structure employing a framework wall construction
method.
[0103] With this arrangement, it is possible to obtain a siding
boards attachment structure enabling easy construction. It is also
possible to obtain a siding boards attachment structure exhibiting
satisfactory strength.
[0104] It should be noted that details of the framework wall
construction method will be described later.
[0105] It is preferable that a lower rabbeted horizontal edge of a
lowermost siding board is located to be remote from the ground
surface.
[0106] With this arrangement, it is possible to prevent the
lowermost siding board from absorbing moisture directly from the
ground surface, thus corrosion or degradation of the siding board
can be prevented.
[0107] Thus, it is possible to obtain a siding boards attachment
structure exhibiting superior durability.
[0108] It is further preferable that a starter member that is fixed
to the framework together with the lowermost fastening member is
disposed at a lowermost end of the siding boards attachment
structure.
[0109] With this arrangement, it is possible to reliably obtain a
siding boards attachment structure with the lowermost siding board
being remote from the ground surface by a specified distance. Since
a continuous footing of the siding boards attachment structure may
be hidden thereby, the external appearance of design may also be
improved.
[0110] The starter member preferably includes a leg plate that is
located to be proximate to the ground surface, a bottom plate
abutting against a lower end portion of the fastening member, and a
back plate to be fixed to the framework,
[0111] wherein the leg plate is of a length that is substantially
identical to a distance between the exterior wall plate mounted to
the fastening member and the ground surface.
[0112] The "lower end portion of the fastening member" denotes an
end portion that is located downward when the fastening member is
disposed at the framework.
[0113] More particularly, when fixing the fastening member by a
nail, the lower end of the lower abutting portion of the fastening
member abuts on the bottom plate of the starter member (see FIG.
8), and when fixing the fastening member by a screw, the direction
of the fastening member is turned upside down so that an upper end
of the upper abutting portion abuts on the bottom plate.
[0114] With this arrangement, it is possible to obtain more easily
and reliably a siding boards attachment structure in which the
siding board at the lowermost end is remote from the ground surface
by a specified distance.
[0115] According to another aspect of the invention, a starter
member is used together with a lowermost fastening member and is
disposed at a lower end portion of a siding boards attachment
structure,
[0116] wherein the starter member includes a leg plate that is
located proximate to the ground surface, a bottom plate abutting
against a lower end portion of the fastening member, and a back
plate to be fixed to the framework,
[0117] wherein the leg plate is in a length that is substantially
identical to a distance between the exterior wall plate mounted to
the fastening member and the ground surface (see FIGS. 8 and
9).
[0118] By using the starter member of the present invention, the
siding board at the lowermost end may be easily and reliably
constructed to be remote from the ground surface by a specified
distance. The starter member is further capable of hiding a
continuous footing of the siding boards attachment structure, thus
the external appearance of design can be improved.
[0119] It is preferable that the starter member includes a crown
plate projecting frontward from the back plate for abutting against
a rear side surface of the siding board.
[0120] With this arrangement, the starter member may be easily and
stably constructed.
[0121] The crown plate preferably includes ventilating holes.
[0122] With this arrangement, outside air is introduced to between
the rear side surfaces of the siding boards and the underlayments
so that ventilation of the interior of the siding boards attachment
structure may be permanently performed. Thus, the durability of the
siding boards attachment structure may be improved.
[0123] It is preferable that the ventilating holes are covered with
mesh-like bodies.
[0124] With this arrangement, it is possible to prevent vermin such
as termites or bees from entering the rear side of the siding board
through the ventilating holes. Thus, it is possible to prevent
degradations of the siding board, underlayment, the framework and
the like.
[0125] It is preferable that the leg plate is formed with a notched
groove for adjusting its length.
[0126] With this arrangement, the leg plate may be cut at the
notched groove for easily adjusting the length thereof.
[0127] The notched groove is preferably formed at a plurality of
spots. In this case, the length of the leg plate may be adjusted in
accordance with various conditions for constructions such that the
siding boards attachment structure may be constructed.
[0128] According to the other aspect of the invention, a method of
attaching siding boards includes
[0129] a first process of fixing a fastening member at a lowermost
stage of the siding boards attachment structure to a framework with
an underlayment being interposed between by a nail or a screw,
[0130] a second process of engaging a lower rabbeted horizontal
edge of a siding board at the fastening member for disposing the
siding board with the rear side surface thereof opposing to the
framework, and
[0131] a third process of disposing another fastening member to an
upper rabbeted horizontal edge of the siding board and fixing the
fastening member to the framework with the underlayment being
interposed between by a nail or a screw,
[0132] wherein the second process and third process are
sequentially repeated after performing the third process,
[0133] wherein in case of that nails are used in the first process
and third process, the nail hole is disposed upward of the support
portion for engaging the fastening member to a lower siding board
and the nail is pierced through the nail hole for fixing the
fastening member to the framework with the underlayment being
interposed between,
[0134] while in case of that screws are used in the first process
and third process, the screw hole is disposed upward of the support
portion for engaging the fastening member to a lower siding board
and the screw is pierced through the screw hole for fixing the
fastening member to the framework with the underlayment being
interposed between.
[0135] It is a notable point of the method of attaching siding
boards that in case of that the fastening member is fixed by nails
in the first process and third process, the nail hole is disposed
upward of the support portion while the screw hole is disposed
upward of the support portion in case of that the fastening member
is fixed by screws.
[0136] Thus, in case of that the screw hole is provided downward of
the support portion, that is, on an opposite side of the nail hole,
the direction of the fastening member needs to be turned upside
down when fixing is performed with the screw in contrast to a case
in which fixing is performed with the nail. In this case, the upper
board engaging portion will engage the lower siding board and the
lower board engaging portion will engage the upper siding
board.
[0137] The positional relationship of the nail and the screw from
the support portion will be substantially identical, when the nail
and the screw is used. Thus the fixing force of the fastening
member to the framework will be stable.
[0138] Thus, according to the above method of constructing exterior
walls, it is possible to construct a siding boards attachment
structure with which hardly any differences in fastening force of
siding boards will be caused owing to differences in means for
fixing the fastening member to the framework.
[0139] Embodiment 1
[0140] The fastening member and the siding boards attachment
structure according to embodiments of the present invention will
now be explained with reference to FIGS. 1 to 10(B).
[0141] FIGS. 1, 2(A) and 2(B) are explanatory views of a fastening

bent upward from the support portion 12, and a lower board engaging
portion 14 that is bent downward from the support portion 12. A
front flat plate portion 134 abutting against a rear surface of an
overlying tongue portion 226 of a lower overlying tongue portion of
the upper siding board 2 is formed frontward of the upper board
engaging portion 13 and the lower board engaging portion 14.
[0145] The base plate portion 11 includes a nail hole 18 and a
screw hole 19 for piercing a nail 41 and a screw 42, respectively,
through for fixing the fastening member 1 to the framework with the
underlayment 3 being interposed between.
[0146] As illustrated in FIG. 2(B), the nail hole 18 and the screw
hole 19 are provided at positions where distances from the nail
hole 18 and the screw hole 19 to the support portion 12 are
substantially equal. More particularly, a vertical distance A from
a central plane of the support portion 12 to the nail hole 18 and a
vertical distance B from the central plane of the support portion
12 to the screw hole 19 are substantially equal.
[0147] As illustrated in FIGS. 1, 2(A), 2(B), 4 and 6, the base
plate portion 11 includes an upper abutting portion 111 and a lower
abutting portion 112 that abut on the underlayment 3 at its upper
and lower portion. It further includes an upper rising portion 113
and a lower rising portion 114 that are respectively formed in a
frontward rising manner from the upper abutting portion 111 and the
lower abutting portion 112.
[0148] The base plate portion 11 further includes a central plate
portion 115 for connecting the upper rising portion 113 and the
lower rising portion 114 and further abutting against the rear side
surfaces 26 of the siding boards 2, wherein the support portion 12

[0149] As illustrated in FIGS. 1 and 2(B), the upper rising 20
portion 113 and the lower rising portion 114 include horizontal
plane portions 15, 16 that are arranged at a substantially right
angle with respect to the central plate portion 115.
[0150] The upper rising portion 113 includes a sloped portion 17
wherein the nail hole 18 is formed on the sloped portion 17. The
upper abutting portion 111 and the lower abutting portion 112
include abutting surfaces 116 and 117 that are substantially
horizontal to the central plate portion 115.
[0151] The fastening member 1 is manufactured by, for instance,
extrusion molding of aluminum.
[0152] The siding boards attachment structure 7 using the fastening
member 1 will now be explained with reference to FIGS. 3 to 8.
[0153] As illustrated in FIGS. 3 to 6, the siding boards attachment
structure 7 is arranged by disposing the fastening member to bridge
from the upper rabbeted horizontal edge 21 of the lower siding
board 2 and the lower rabbeted horizontal edge 22 of the upper
siding board 2 for mounting the siding boards 2 to the stud 31 of
the framework with the underpayment 3 being interposed between.
[0154] As illustrated in FIGS. 3 and 4, in case of that the
fastening member 1 is fixed to the stud 31 with the underlayment 3
being interposed between by the nail 41, the nail hole 18 is
disposed upward of the support portion 12 and the nail 41 is
pierced through the nail hole 18 and driven in an oblique downward
direction for fixing.
[0155] On the other hand, as illustrated in FIGS. 5 and 6, in case
of that the fastening member 1 is fixed to the stud 31 with the
underlayment 3 being interposed between by the screw 42, the screw
hole 19 is disposed upward of the support portion 12 and the screw
42 is pierced through the screw hole 19 and screwed in a horizontal
direction for fixing.
[0156] The siding board 2 constructing the siding boards attachment
structure 7 is a siding board of a four side (left, right, upper
and lower sides) shiplap structure as illustrated in FIG. 7. More
particularly, the siding board 2 includes an upper underlying
tongue portion at the upper rabbeted horizontal edge 21, a lower
overlying tongue portion at the lower rabbeted horizontal edge 22,
a lateral underlying tongue portion at a right rabbeted vertical
edge 23 and a lateral overlying tongue portion at a left rabbeted
vertical edge 24. Caulking materials 29 for preventing penetration
of water from joint portions of siding boards 2 after construction
are attached on a front surface of the upper underlying tongue
portion and a front surface of the lateral underlying tongue
portion.
[0157] As illustrated in FIG. 8, a distance H between the lower
rabbeted horizontal edge 22 of a siding board 2 that is disposed at
a lowermost stage and the ground surface 5 is set to be, for
instance, 6 inches in the siding boards attachment structure 7. As
a means thereof, the starter member 6 is disposed at the lowermost
end of the siding boards attachment structure 7 together with the
fastening member 1 at the lowermost end.
[0158] As illustrated in FIGS. 8 and 9, the starter member 6
includes a leg plate 61 abutting the ground surface 5, a bottom
plate 62 abutting the lower end portion of the fastening member 1,
and a back plate 63 for fixing on the underlayment 3.
[0159] The bottom plate 62 is arranged at a position at which it is
substantially the same height as the siding board 2 that is mounted
to the fastening member 1 is to be disposed remote from the ground
surface 5 as in the above-explained manner. That is, the bottom
plate 62 is formed at a position at which a distance i from a lower
end portion 612 of the starter member 6 is, for instance,
approximately 6 inches.
[0160] The lower end portion of the leg plate 61, that is, the
lower end portion 612 of the starter member 6 is bent backward to
form a plane portion on a substantially identical plane as the back
plate 63 and is located to be proximate to the ground surface 5 for
improving the external appearance of design.
[0161] The starter member 6 includes a crown plate 64 projecting
frontward from the back plate 63 and abutting against rear side
surfaces 26 of the siding boards 2. As illustrated in FIGS. 8 and
9, the crown plate 64 includes a front flat plate portion 641 at a
front end portion thereof and is provided with ventilating holes 65
as illustrated in FIG. 10(A).
[0162] As illustrated in FIGS. 9 and 10 (B), the leg plate 61 is
formed with a notched groove 611 at a specified position such that
its length is adjustable in accordance with conditions at
construction sites. The notched groove 611 may be formed in a
horizontal manner at a position, for example, 4 inches from the
lower end portion of the leg plate 61.
[0163] The siding boards attachment structure 7 (FIGS. 3 to 8) is a
constructing structure employing a framework wall construction
method, and in case of performing construction, the framework is
assembled in the following manner.
[0164] That is, a plurality of square timbers in which sectional
dimensions are identical are used for first assembling a plurality
of wall frameworks 30. The square timber generally has a sectional
dimension of 2.times.4 inches, and intervals between studs 31 of
the wall frameworks 30 may be, for instance, 16, 20 and 24
inches.
[0165] These wall frameworks 30 are assembled on a continuous
footing 300 as a framework of a building (FIG. 8).
[0166] As illustrated in FIGS. 3 to 6, underlayments 3 made, for
instance, of foamed plastic resin boards having a thickness of 12
mm, are fixed to the wall frameworks 30 from outside of the
framework by using nails of lengths of approximately 30 mm. This is
a simple constructing method in which construction of
heat-insulating materials is completed at the time of constructing
the siding boards without forming bearing walls.
[0167] It should be noted that oriented strand boards (OSBs) can be
used as the underlayments 3.
[0168] Particularly, the siding boards 2 are fastened to the
assembled wall frameworks 30, that is, the framework (studs 31)
with the underlayments 3 being interposed between in the following
manner.
[0169] In a first process, the fastening member 1 at the lowermost
stage of the siding boards attachment structure 7 is fixed to a
sill 32 with the underpayment 3 being interposed between as
illustrated in FIG. 8.
[0170] In this case, waterproof paper 33 is adhered to an outside
surface of the underlayment 3 by using a double-faced adhesive tape
or the like. Then, the starter member 6 is disposed such that the
lower end portion 612 thereof is proximate to the ground surface 5
and the fastening member 1 is mounted on the bottom plate 62 of the
starter member 6 for fixing the fastening member 1 to the sill 32
with the underlayment 3 being interposed between (FIG. 8).
[0171] In case of that the fastening member 1 is fixed to the
underlayment 3 by the nail 41, the nail hole 18 is disposed upward
of the support portion 12 and the nail 41 is pierced through the
nail hole 18 for driving the nail 41 in an oblique downward
direction for fixing the fastening member 1 to the sill 32 with the
underlayment 3 being interposed between as illustrated in FIG.
8.
[0172] On the other hand, in case of that the fastening member 1 is
fixed to the underlayment 3 by the screw 42, the screw hole 19 is
disposed on upward of the support portion 12 and the screw 42 is
pierced through the screw hole 19 for screwing the screw 42 in a
horizontal direction for fixing the fastening member 1 to the sill
32 with the underlayment 3 being interposed between (see FIGS. 5
and 6).
[0173] In a second process, the lower overlying tongue portion of
the lower rabbeted horizontal edge 22 of a siding board 2 that is
to be disposed at a lowermost stage is engaged at the upper board
engaging portion 13 of the fastening member 1 to be disposed to
face the underlayment 3 (see FIG. 8).
[0174] For joining laterally disposed siding boards 2, the siding
boards 2 are fastened such that butt portions of the right rabbeted
vertical edge 23 and the left rabbeted vertical edge 24 of the
siding boards 2 are disposed at positions where studs 31 of the
wall frameworks 30 are present as illustrated in FIGS. 3 and 5.
[0175] In this manner, in case of joining in lateral directions,
the lateral overlying tongue portion of the left rabbeted vertical
edge 24 of the right siding board 2 is overlapped onto the lateral
underlying tongue portion of the right rabbeted vertical edge 23 of
the left siding board 2 that has been fastened before, and both are
joined through right-and-left shiplap jointing, as illustrated in
FIGS. 3 and 5.
[0176] In a third process, another fastening member 1 is disposed
on the upper rabbeted horizontal edge 21 of a siding board 2 that
is disposed on the lowermost stage in the above-described manner,
and is fixed to the stud 31 with the underlayment 3 being
interposed between by the nail 41 or the screw 42.
[0177] As illustrated in FIGS. 3 and 4, in case of fixing the
fastening member 1 to the underlayment 3 by a nail 41, the nail
hole 18 is disposed upward of the support portion 12 and the
fastening member 1 is engaged at the upper rabbeted horizontal edge
21 of the lower siding board 2. That is, the upper rabbeted
horizontal edge 21 of the lower siding board 2 is inserted into
space formed by the base plate portion 11, the support portion 12,
and the lower board engaging portion 14 of the fastening member
1.
[0178] At this time, the lower board engaging portion 14 is engaged
at the upper rabbeted horizontal edge 21 of the siding board 2 and
the horizontal plane portion 15 formed at the upper rising portion
113 of the fastening member 1 is lightly hit from above by a hammer
or the like for fitting the fastening member 1 to the siding board
2 reliably.
[0179] The nail 41 is then pierced through the nail hole 18 and
driven in an oblique downward direction for fixing the fastening
member 1 to the stud 31 with the underlayment 3 being interposed
between.
[0180] On the other hand, as illustrated in FIGS. 5 and 6, in case
of fixing the fastening member 1 to the underlayment 3 by a screw
42, the screw hole 19 is disposed upward of the support portion 12
and the fastening member 1 is engaged at the upper rabbeted
horizontal edge 21 of the lower siding board 2. That is, the
direction of the fastening member 1 is turned upside down in
contrast to the above-described case in which fixing is performed
by using the nail 41 (FIGS. 3 and 4).
[0181] Then, the fastening member 1 is engaged at the upper
rabbeted horizontal edge 21 of the lower siding board 2. That is,
the upper rabbeted horizontal edge 21 of the lower siding board 2
is inserted into space formed by the base plate portion 11, the
support portion 12, and the upper board engaging portion 13 of the
fastening member 1.
[0182] At this time, the upper board engaging portion 13 is engaged
at the upper rabbeted horizontal edge 21 of the siding board 2 and
the horizontal plane portion 16 formed at the lower rising portion
114 of the fastening member 1 is lightly hit from above by a hammer
or the like for fitting the fastening member 1 to the upper
rabbeted horizontal edge 21 of the siding board 2 reliably.
[0183] The screw 42 is then pierced through the screw hole 19 and
screwed in a horizontal direction for fixing the fastening member 1
to the stud 31 with the underlayment 3 being interposed
between.
[0184] In this manner, in case of joining in vertical directions as
illustrated in FIGS. 4 and 6, the lower overlying tongue portion of
the lower rabbeted horizontal edge 22 of the tipper siding board 2
is overlapped onto the upper underlying tongue portion of the
tipper rabbeted horizontal edge 21 of the lower siding board 2 that
has been fastened before, and both are joined through an
upper-and-lower shiplap jointing.
[0185] After completing the third process, the same processes as
the second process and third process are sequentially repeated.
[0186] The working effect of the present example will be
explained.
[0187] In the above fastening member 1, the nail hole 18 and the
screw hole 19 are disposed at positions where a distance from the
nail hole 18 to the support portion 12 and a distance from the
screw hole 19 to the support portion 12 become substantially equal
(FIGS. 2(A), 2(B)). Thus, hardly any differences are caused in
fixing force of the upper siding board 2 against load or wind
pressure in case of fixing the fastening member 1 by the nail 41
(FIGS. 3 and 4) and the case of fixing the fastening member 1 by
the screw 42 (FIGS. 5 and 6).
[0188] Thus, hardly any differences are caused in fastening force
of the siding boards 2 when constructing the siding boards
attachment structure 7 by fixing the fastening member 1 by using
either the nail 41 or the screw 42. In other words, hardly any
differences are caused in fixing force of the upper siding board 2,
no matter whether the siding boards attachment structure 7 is
constructed by fixing the fastening members 1 using only nails 41
or the siding boards attachment structure 7 is constructed by
fixing the fastening members 1 using only screws 42.
[0189] More particularly, no drawbacks such as isolation or falling
off of siding boards 2 will be caused by varying the means for
fixing the fastening members 1. Particularly performances such as
wind-pressure resistance of the siding boards attachment structure
7 will not be varied depending on means for fixing the fastening
members 1.
[0190] Since a person performing the construction may freely select
the fixing means for the fastening members 1, that is, nails 41 or
screws 42, in accordance with various conditions in performing
construction, easy construction is enabled.
[0191] The base plate portion 11 of the fastening member 1 includes
the upper abutting portion 111, the lower abutting portion 112, the
upper rising portion 113, the lower rising portion 114, and the
central plate portion 115.
[0192] With this arrangement, a ventilation layer 71 is formed
between the rear side surfaces 26 of the siding boards 2 and the
underlayments 3 in the siding boards attachment structure 7 as
illustrated in FIGS. 4, 6 and 8, so that condensation is prevented
and the durability of the siding boards attachment structure 7 is
improved.
[0193] As illustrated in FIGS. 8, 9 and 10 (A), ventilating holes
65 are formed in the crown plate 64 of the starter member 6
disposed at the lowermost end of the siding boards attachment
structure 7.
[0194] Therefore, outside air 79 from below is introduced to the
ventilation layer 71 through the ventilating holes 65 and the
introduced outside air 79 is exhausted from above.
[0195] With this arrangement, it is possible to prevent
accumulation of humidity on rear sides of the siding boards 2 or on
the underlayments 3, and corrosion of the underlayments 3 or studs
31 will not occur so that is possible to improve the durability of
the siding boards attachment structure 7 largely.
[0196] Since the upper rising portion 113 and the lower rising
portion 114 of the fastening member 1 includes horizontal plane
portions 15, 16 that are arranged to form a substantially right
angle with respect to the central plate portion 115, easy
construction is enabled.
[0197] More particularly, by hitting the horizontal plane portion
15 or 16 lightly by a hammer or the like when fitting the upper
rabbeted horizontal edge 21 of the lower siding board 2 to the
fastening member 1 in the above-described manner, reliably fitting
with the fastening member 1 is enabled in an easy manner.
[0198] Since the upper rising portion 113 includes a sloped portion
17 on which the nail hole 18 is formed, the nail 41 may be pierced
through the nail hole 18 to be driven into an oblique downward
direction with respect to the stud 31 with the underlayment 3 being
interposed between (FIG. 4). Thus, the fastening member 1 may be
reliably fixed to the stud 31 with the underlayment 3 being
interposed between and further be reliably engaged to the lower
siding board 2.
[0199] The upper abutting portion 111 and the lower abutting
portion 112 includes abutting surfaces 116 and 117. Thus, the
contact surface of the upper abutting portion 111 and the lower
abutting portion 112 with the underlayment 3 may be large so as to
prevent cutting of the upper abutting portion 111 and the lower
abutting portion 112 into the underlayment 3.
[0200] That is, the provision of the abutting surfaces 116, 117 at
the upper abutting portion 111 and the lower abutting portion 112
of the fastening member 1 will prevent cutting of the upper
abutting portion 111 and the lower abutting portion 112 into the
underlayments 3 though the underlayments 3 are made of foamed resin
panels to be soft materials. Thus, it is possible to prevent the
fastening member 1 from sinking into the underlayments 3.
[0201] Thus, the siding boards 2 may be fastened to the studs 31
stably with the underlayments 3 being interposed between.
[0202] Since the siding boards attachment structure 7 is a
construction structure employing the framework wall construction
method, easy construction is enabled.
[0203] The lower rabbeted horizontal edge 22 of the siding board 2
at the lowermost stage of the above siding boards attachment
structure 7 is remote from the ground surface 5 (FIG. 8). Thus, it
is possible to prevent the lowermost siding board 2 from absorbing
moisture directly from the ground surface 5. Thus corrosion or
degradation of the siding board 2 may be prevented. It is therefore
possible to obtain a siding boards attachment structure 7
exhibiting superior durability.
[0204] More particularly, since the starter member 6 is disposed at
the lowermost end of the siding boards attachment structure 7
together with the fastening member 1 at the lowermost end, it is
possible to reliably obtain a siding boards attachment structure 7
in which the siding board 2 of the lowermost stage is remote from
the ground surface 5 by a specified distance. Since the continuous
footing 300 is hidden by the starter member 6, it is also possible
to exhibit superior external appearance of design.
[0205] The provision of the crown plate 64 of the starter member 6
that abuts the rear side surface 26 of the siding board 2, the
starter member 6 may be constructed in an easy and stable
manner.
[0206] Since the crown plate 64 is provided with ventilation holes
65, outside air 79 may be introduced to the ventilation layer 71
between the rear side surfaces 26 of the siding boards 2 and the
underlayments 3 such that permanent ventilation of the siding
boards attachment structure 7 is enabled. Thus, the durability of
the siding boards attachment structure 7 may be improved.
[0207] Since the leg plate 61 is formed with a notched groove 611
for length adjustment purposes, the leg portion 61 may be cut at
the notched groove 611 in accordance with conditions for
construction, thereby enabling easy adjustment to the length
thereof.
[0208] As explained so far, according to the present example, it is
possible to provide a fastening member and a siding boards
attachment structure with which hardly any differences are caused
in fastening force of the siding boards owing to differences in
means for fixing (either nails or screws) to the studs 31 with the
underlayments 3 being interposed between.
[0209] Embodiment 2
[0210] As illustrated in FIG. 11, the present example is an example
of a fastening member 10 in which surfaces of the abutting surfaces
116 and 117 of the upper abutting portion 111 and the lower
abutting portion 112 are further enlarged.
[0211] As illustrated in FIG. 11, the fastening member 10 is formed
by folding a single metallic plate such as one made of stainless
steel.
[0212] At the upper end portion of the upper abutting portion 111,
the metallic plate is folded back in a downward direction such that
the abutting surface 116 is formed in a further downwardly
elongated manner than the upper rising portion 113. The lower end
portion of the lower abutting portion 112 is similarly arranged in
that the metallic plate is folded back in an upward direction such
that the abutting surface 117 is formed in a further upwardly
elongated manner than the lower rising portion 114.
[0213] The remaining arrangements are similar to those of the
Embodiment 1.
[0214] In this case, the contact surface between the underlayment
and the fastening member 10 will be larger when the fastening
member 10 is fixed to the framework with the underlayment
interposed between. Thus, it is possible to prevent the fastening
member 10 from sinking into the underlayment in an even more
reliably manner also when performing fixing with underlayments of
soft materials interposed between. Thus, it is possible to obtain
an even more stable siding boards attachment structure.
[0215] Other working effects are similar to those of the Embodiment
1.
[0216] Embodiment 3
[0217] As illustrated in FIG. 12, the present example is an example
of a fastening member 100 in which protruding portions 101 and 102
projecting frontward are provided at an upper end of the upper
abutting portion 111 and a lower end of the lower abutting portion
112.
[0218] The remaining arrangements are similar to those of the
Embodiment 1.
[0219] In this case, by hitting the protruding portion 101 or 102
lightly by a hammer or the like, the fastening member 100 may be
easily and reliably fitted to an upper rabbeted horizontal edge of
a siding board that is disposed on a lower side.
[0220] When using the fastening member 100 with the nail hole 18
being positioned above the support portion 12, the fastening member
100 may be fitted to the siding board by lightly hitting the
protruding portion 101 formed at the upper abutting portion 111. On
the other hand, when using the fastening member 100 with the screw
hole 19 being positioned above the support portion 12, the
fastening member 100 maybe fitted to the siding board by lightly
hitting the protruding portion 102 formed at the lower abutting
portion 112.
[0221] Other working effects are similar to those of the Embodiment
1.
[0222] Embodiment 4
[0223] As illustrated in FIG. 13, the ventilation holes 65 provided
on the crown plate 64 of the starter member 6 is covered by
mesh-like bodies 651.
[0224] The remaining arrangements are similar to those of the
Embodiment 1.
[0225] With this arrangement, it is possible to prevent vermin such
as termites or bees from entering the rear side of the siding board
through the ventilating holes 65. Thus, it is possible to prevent
degradations of the siding board, underlayment and the like.
[0226] Other working effects are similar to those of the Embodiment
1.
[0227] Embodiment 5
[0228] As illustrated in FIGS. 14 to 16, the present example is an
example of fastening member 1a that is of laterally elongated
shape.
[0229] FIG. 14 is a front view of the fastening member 1a, FIG. 15
is a perspective explanatory view of a siding boards attachment
structure 7a using the fastening member 1a, and FIG. 16 is a
lateral sectional explanatory view of the siding boards attachment
structure 7a.
[0230] As illustrated in FIGS. 15 and 16, the fastening member 1a
is arranged such that a plurality of studs 31 of a framework that
are disposed in a laterally aligned manner may be connected and
fixed. More particularly, the length of the fastening member 1a in
a lateral direction is set to be approximately 68 cm while the
length in a vertical direction is set to be approximately 4.5
cm.
[0231] The remaining arrangements are similar to those of the
Embodiment 1.
[0232] With this arrangement, lateral siding boards 2 may be
reliably mounted to the framework with the underlayment 3 being
interposed between also in case the left rabbeted vertical edge 23
and the right rabbeted vertical edge 24 of the siding board 2 are
not disposed on the stud 31 of the framework as illustrated in
FIGS. 15 and 16.
[0233] More particularly, in case of using the fastening member 1a
in the siding boards attachment structure 7a employing the
framework wall construction method, the fastening member 1a needs
to be disposed at a portion at which the stud 31 is present for
securing strength. On the other hand, the fastening member 1a needs
to be disposed to bridge from the upper rabbeted horizontal edge 21
to the lower rabbeted horizontal edge 22 formed on a corner portion
of the siding board 2.
[0234] At this time, when the left rabbeted vertical edge 23 or the
right rabbeted vertical edge 24 of the siding board 2 is not
disposed on the stud 31, that is, the corner portion of the siding
board 2 is not positioned on the stud 31, the fastening member 1a
can not be disposed on a portion on which the stud 31 is present
and the corner portion of the siding board 2 is present in case of
that the lateral length of the fastening member 1a is short.
[0235] Thus, by arranging the fastening member 1a to be of a shape
that is elongated in lateral directions for enabling connection and
fixing of a plurality of studs 31, it will be possible to arrange a
siding boards attachment structure 7a exhibiting satisfactory
strength (FIGS. 15 and 16).
[0236] Other working effects are similar to those of the Embodiment
1.
[0237] Obviously, numerous modifications and variations of the
present invention are possible in light of the above teachings. It
is therefore to be understood that, within the scope of the
appended claims, the invention may be practiced otherwise than as
specifically described here.
