Wall Exterior Structure for Outer Wall Heat-Insulated Building and
Wall Exterior Base, Lateral Furring Frame for Wall Exterior
Material Installation and Method for Covering Wall Using Lateral
Furring Frame, and Exterior Base Material and Outer Wall Using
Exterior Base Material
Abstract
In a wall exterior structure, an exterior base is formed of a
number of vertical furring strips and a number of lateral furring
strips, which are arranged in lattice to each other, each furring
strip being a C-shaped channel material. A latch tongue, formed to
an upright piece of each vertical furring strip, is latched to an
upper through hole in each lateral furring strip. The upright piece
is disposed at the position where a vertical furring strip
intersects a lateral furring strip. The exterior base is provided
by fixing the vertical furring strips on the surface of an outer
heat insulating layer. An exterior material is hung to the exterior
base so that an outer wall is made through a simple work. A
ventilation space of about 5 mm, depending on the thickness of the
vertical furring strip, is defined outside the outer heat
insulating layer. The ventilation space is generally about 2 cm in
thick. Hence, the reduced ventilation space can improve the heat
insulation property of a building.

Description
TECHNICAL FIELD
[0001] The present invention relates to a wall exterior structure
for an outer wall heat-insulated building and to a wall exterior
base. Furthermore, the present invention relates to a lateral
furring frame for wall exterior material installation and to a
method for covering walls using the lateral furring frame.
Moreover, the present invention relates to an exterior base
material and to an outer wall using the exterior base material.
[0002] In more detail, the present invention is made to mount a
surface exterior portion to an outer wall via an outer heat
insulated layer in a building such as a single-family house. For
that purpose, the present invention relates to improving (1) a wall
exterior structure and a base for the wall exterior, (2) a lateral
furring frame for wall exterior material installation (metallic
lateral furring frame) and a method for covering a wall surface
using the lateral furring frame, and (3) an exterior base material
and outer wall using the base material.
BACKGROUND OF THE RELATED ART
[0003] Conventionally, to construct an exterior structure, a
surface exterior portion is mounted to an outer wall surface,
acting as the structural frame of a building, via a suitable outer
heat insulation layer. Moreover, a desired ventilation space is
defined between the outer heat insulation layer and the surface
exterior portion. The existence of the ventilation space provides
high heat insulation and/or high air tightness to the surface
exterior portion itself. Such a wall heat-insulated building is
well known.
[0004] As to general buildings including surface exterior portions
each in which an outer heat insulation layer is disposed to the
above-mentioned outer wall surface via a ventilation space, the
wall exterior structure is disclosed in Japanese Patent laid-open
publication No. Tokkai 2000-204688.
[0005] In the conventional wall exterior structure, plural wooden
furring strips are used. First, furring strips are arranged in
parallel on the surface of a structural panel spread over the outer
wall surface of a building, via desired spacers, and plural
longitudinal portions are securely fixed by means of metal
fittings. By doing so, required rows of furring strips are prepared
as exterior bases.
[0006] Next, with the furring strip rows left on the surface,
respective spacers are embedded in the outer heat insulation layer
foamed in the construction site. An exterior structure is
constructed through loading outer materials, for example, exterior
tiles or plate sidings, over the surfaces of the remaining furring
strip rows.
[0007] In this case, a ventilation space, having a gap equal to or
near to the depth of the furring strip rows, is defined between
each exterior material and outer heat insulation layer suspended
over the surface of a structural panel. By doing so, an exterior
structure having a ventilation space is completed in the outer wall
heat-insulated building.
[0008] In the case of the conventional structure, the furring strip
is about 3 cm in width and about 2 cm in thick. As a result, the
gap of the ventilation space is about 2 cm, corresponding to the
thickness of the furring strip row.
[0009] However, the conventional structure requires attachment of
spacers onto exterior surfaces of an outer wall acting as a
structural frame and formation of foamed outer heat insulation
layers at the construction site. Therefore, undesired problem is
that the heat insulation external work on the construction spot is
complicated and much hours of work are consumed.
[0010] In such a case, respective furring strips, which support the
whole weight of a heat insulation structure such as an exterior
material, are fixed via spacers to the surface exterior portion on
a structural panel, by means of fittings such as screwed nails.
Hence, the whole load acts on the fittings via each furring strip.
As a result, it is unavoidable that a failure such as deflection of
mounting shafts of the fittings may be induced. For that reason, in
sufficient consideration of the load due to exterior materials, an
exterior structure having predetermined ventilation space
(ventilation gap) must be constructed within an allowable effective
length of the mounting shafts of fittings.
[0011] In the illustration in the above-mentioned prior art
document, the total dimension (gap dimension) between each furring
strip and the surface of an outer wall acting as a structural frame
is usually set to an actual length of about 5 cm. For that reason,
the effective thickness of the structural panel is about 5 cm. If
the effective thickness of the structural panel is about 0.5 cm and
the thickness of each furring strip is about 2 cm, the thickness of
an outer heat insulation layer formed through the foaming process
at the construction site ranges 2.5 cm to 3 cm.
[0012] If the total dimension between the exterior surface and the
furring strip is set to a relative large value or the thickness of
the furring strip is set to a small value, the outer heat
insulation layer can be thickened at least by the set value. By
doing so, it is clear that the heat insulation performance of the
building itself is more improved, thus providing an exterior
structure more effectively.
[0013] However, the total dimension between the surface of the
exterior portion and each furring step is generally limited to
about 7 cm. More increasing the total dimension leads to
excessively lengthening the effective shaft length of the fixing
tool. The increased dimension leads to easily deflecting the shaft
and decreasing the overall strength, as described preciously.
Hence, the total dimension cannot be set to a critical value or
more. Moreover, since the furring strip is made of wood, a
reasonable material strength must be usually reserved. Hence, the
thickness of each furring strip cannot be reduced.
[0014] In such a case, when a foamed heat insulated panel is used
as one structural aspect of the outer heat insulation layer, the
thickness of the outer heat insulation layer is limited to at most
about 3 cm to 5 cm because the total dimension is limited due to
the effective length of the shaft of a fixing tool. As a result, it
is impossible to improve the heat insulation performance of a
building by disposing outer heat insulation layers having a more
thickness than the critical thickness.
[0015] A furring strip in a standard unit set to a predetermined
length (hereinafter, referred to as "standard lateral furring
strip") is often used as a furring strip for a wall exterior base
constructing the wall exterior, particularly, as a horizontally
arranged furring strip. The standard lateral furring strip is
mounted to an outer wall acting as the structural frame alone or is
mounted via other furring strip (referred to as "a vertical furring
strip" to distinguish clearly from "the standard lateral furring
strip"). The resultant structure is called an outer exterior
material mounting base.
[0016] The standard lateral furring strip has protruded lines or
engagement rails, running in parallel to both edges thereof. The
outer exterior material, for example, the recesses on the back side
of an exterior tile are hooked to the engagement rails (refer to
Japanese Patent Laid-open Publication No. Tokkai 2003-172012).
[0017] In such a case, on the ground of manufacture, the standard
lateral furring strip, which has the length longer than the
distance between the center of a main column and the center of an
intermediate column in the axial or frame assembling structure of a
building, may be set as a standard section. Alternatively, a
predetermined length, which is an integral multiple number of the
center to center distance, in compliance with Shaku (an old unit in
Japanese measuring system) or a metric unit, may be set as a
standard length. The standard lateral furring strips are arranged
horizontally and continuously in line on the outer wall surface
while the ends are butting horizontally and longitudinally to each
other.
[0018] However, since the ends such as outer corners or windows are
provided at many places in an actual building, the horizontal
widths are not fixed. Even if the standard furring strips, having a
length larger than the center to center distance or having a length
equal to the center to center distance, are used, the total length
in arrangement does not match with the structural width. At the
construction site, one side of the lateral furring strip may
protrude as an extra portion from the end or may be short to the
end.
[0019] Therefore, at the construction site, the extra portion is
cut and removed while the same material is spliced to the shortage.
This makes it very complicated to perform working at the
construction site and raises undesired problems.
DISCLOSURE OF THE INVENTION
[0020] The present invention is made to improve the above-mentioned
previous problems. A first object of the present invention is to
provide a wall exterior structure for outer wall heat insulated
buildings, wherein the external finish can be performed certainly
and easily for the whole surface of outer heat insulated outer wall
at a construction site. Moreover, the present invention can stably
latch the outer exterior material at all times, can effectively
reserve the proper strength of an outer exterior base, can increase
reasonably the thickness of an outer heat insulated layer to be
produced, and can improve the heat insulation performance.
[0021] A second object of the present invention is to provide a
wall exterior base for the outer wall heat insulated building,
wherein respective outer exterior materials can be latched stably
at all times in a relatively simplified structure.
[0022] A third object of the present invention is to provide a
combination of furring strips of various types for wall exterior
installation in an outer wall heat insulated building, wherein the
cutting and removing works and splicing and compensation are not
required at a construction site so that good workability can be
always established highly and easily. In such a combination, when
lateral furring strips having a fixed length, i.e. standard lateral
furring strips, to be mounted to an outer wall surface are
combined, a redundant portion in length and a short portion in
length, which may occur because of the existence of outer corners
or windows on the outer wall surface, can be compensated
effectively through a simple operation.
[0023] In order to achieve the above mentioned objects, a wall
exterior structure (defined in claim 1) comprises vertical furring
strips arranged vertically and substantially in parallel on a
surface of an outer wall on which an outer heat insulating layer is
formed; lateral furring strips suspended in lattice and
horizontally intersecting with the vertical furring strips; a
furring strip frame, acting as an exterior base, including each
vertical furring strip acting as an inner side and each lateral
furring strip acting as an outer side; and an exterior material
sustained to an engaged portion in a surface of each lateral
furring strip. The vertical furring strip including vertical latch
portions is arranged at predetermined intervals at intersections
between the vertical furring strip and the lateral furring strips.
The lateral furring strip including lateral latch portions paired
with said vertical latch portions. The furring strip frame engages
each lateral latch portion corresponding to said lateral furring
strip sustained to the vertical furring strip, to each vertical
latch portion in the vertical furring strip. A ventilation space
corresponding to a width of the vertical furring strip is defined
between the outer heat insulating layer and the lateral furring
strip.
[0024] In the wall exterior structure, the outer heat insulating
layer is pressed against the surface of said outer wall by the
vertical furring strips arranged on the outer wall surface (defined
in claim 2).
[0025] In the wall exterior structure, the vertical furring strip
has low vertical rims erected at both ends thereof and the lateral
furring strip has low lateral rims erected at both ends thereof.
The lateral latch portion in a base surface between the lateral
rims is paired with and snapped into the vertical latch portion
formed in a base surface between the vertical rims. A gap of the
ventilation space is set by the size of rims protruded at the
lateral latch portion. (defined in claim 3)
[0026] In the wall exterior structure, the lateral furring strips
are orthogonally arranged in lattice with the vertical rims of the
vertical furring strips from the outside. The each lateral latch
portion of the lateral furring strip is snapped into each vertical
latch portion of the vertical furring strip by slidably guiding the
lateral furring strip over the plane of the vertical rims. (defined
in claim 4)
[0027] In the wall exterior structure, the gap of the ventilation
space defined between the exterior base and the outer heat
insulating layer is set to 1 cm or less. (defined in claim 5)
[0028] According to the wall exterior structure for an outer wall
heat insulated building (defined in claims 1 to 5), the wall
exterior structure can be easily constructed on the outer wall
surface of a building. This feature allows the first to third
objects to be achieved certainly and effectively.
[0029] Moreover, according to another aspect of the present
invention (defined in claim 6), a wall exterior base in an outer
wall heat-insulated building, comprises vertical furring strips
arranged vertically and substantially in parallel to an outer wall
surface of a building and each having low rims elected at both ends
of each vertical furring strip; and lateral furring strips
horizontally intersecting vertical rims of each vertical furring
strip and suspended in lattice and having rims erected at both ends
thereof. An exterior material is suspended over the lateral erect
rims of the lateral furring strip. The vertical furring strip is
disposed on said outer wall surface having a vertical latch portion
corresponding to a position where the vertical furring strip
intersects the lateral furring strip. The lateral furring strip has
a lateral latch portion corresponding to a position where the
lateral furring strip intersects the vertical furring strip. The
lateral furring strips are orthogonally arranged in lattice over
the plane of rims of the vertical furring strip from the outside.
The latch portion of the lateral furring strip is snapped into the
latch portion of the vertical furring strip by slidably guiding the
rims of the vertical furring strip.
[0030] According to the wall exterior base for an outer wall heat
insulated building (defined in claim 6), the wall exterior base can
be easily constructed on the outer wall surface of a building. This
feature allows the first to third objects to be achieved certainly
and effectively.
[0031] According to another aspect of the present invention
(defined in claim 7), a lateral furring frame for wall exterior
material installation in an outer wall heat-insulated building,
comprises second vertical furring strips arranged vertically and
substantially parallel to an outer wall surface; second standard
lateral furring strips intersecting horizontally and sustained in
lattice to the second vertical furring strips; and a combination of
the second auxiliary extension furring strip and the second
standard lateral furring strip, acting as a mounting base for
exterior material suspension. The second auxiliary extension
furring strip is combined together with the second standard lateral
furring strip and slidably inserted to the second standard lateral
furring strip. In correspondence with a width in horizontal
direction of the outer wall surface, an end of the second auxiliary
extension furring strip is variably extended from an end in an
elongated direction of the second standard lateral furring
strip.
[0032] In the lateral furring frame, various second standard
lateral furring strips having different standard dimensions are
prepared and the second auxiliary extension furring strips are
combined compatibly to the various second short lateral furring
strips. (defined in claim 8)
[0033] In the lateral furring frame, each of the second standard
lateral furring strip and the second auxiliary extension furring
strip is formed of a shaped metal plate of steel plate, galvanized
sheet iron, or aluminum, shaped through deformation processing such
as roll forming, press forming, and extrusion. (defined in claim
9)
[0034] In the lateral furring frame, the length in lateral
direction of the second auxiliary extension furring strip is
adjusted arbitrarily and slidably with the second auxiliary
extension furring strip combined with the second standard lateral
furring strip. (defined in claim 10)
[0035] In the lateral furring frame, the second auxiliary furring
strip is slidably inserted squarely into the second standard
lateral furring strip and can be sled arbitrarily in the inserted
state. (defined in claim 11)
[0036] The lateral furring frame further (defined in claim 12)
comprises slide regulation means, disposed on both ends of the
second standard lateral furring strip, to travel between the second
standard lateral furring strip and the second auxiliary extension
furring strip or between the second vertical furring strip and the
second auxiliary extension furring strip and through the second
standard lateral furring strip over a desired length range. The
second auxiliary extension furring strip is inserted and sled into
the second short lateral furring strip, within a regulation range
of the slide regulation means.
[0037] In the lateral furring frame, each of the second standard
lateral furring strip and the second auxiliary extension furring
strip has a substantially U-shaped cross section to be slidable,
with the second standard lateral furring strip and the second
auxiliary extension furring strip mutually inserted. The each of
the second furring strip has a furring base formed in a bottom
portion in the U-shaped strip and respective engagement portions
for exterior material suspension, vertically arranged at both ends
on the front side. (defined in claim 13)
[0038] According to the lateral furring strip for wall exterior
material installation used for an outer wall heat insulated
building (defined in claims 7 to 13), the length in lateral
direction of a lateral furring frame, that is, of a combination of
a second standard lateral furring strip and a second auxiliary
extension furring strip, used for the outer wall exterior structure
in a building, can be easily adjusted. In other words, the lateral
length dealing with the outer corner or window in a building can be
easily adjusted. This feature allows the first to third objects to
be achieved certainly and effectively.
[0039] According to another aspect of the present invention
(defined in claim 14), a method for covering wall surfaces with a
lateral furring frame to dispose a wall exterior material of an
outer wall heat insulated building, comprises steps of using a
lateral furring frame for outer exterior installation in any one of
claims 7 to 13 (a lateral furring frame for outer exterior material
installation in which a second standard lateral furring strip and a
second auxiliary extension furring strip are combined together);
and disposing the lateral furring strip for outer exterior material
installation over the entire width of the outer wall surface
through a single or plural second auxiliary extension furring
strip, whereby the outer exterior material is suspended to the
lateral furring frame.
[0040] The wall covering method using a lateral furring frame for
wall exterior installation for an outer wall heat insulated
building (defined in claim 14) allows the first to third objects to
be achieved certainly and effectively.
[0041] According to another aspect of the present invention
(defined in claim 15), a metallic wall exterior material base in an
outer wall heat insulated building, comprises third metallic
vertical furring strips arranged vertically and substantially in
parallel to an outer wall surface; third metallic standard lateral
furring strips suspended in lattice to intersect horizontally the
third metallic vertical furring strips; and third metallic
auxiliary extension furring strips slidably inserted to the third
metallic standard lateral furring strips. The third metallic
standard lateral furring strips and the third metallic auxiliary
extension furring strips act as an exterior material mounting base
for suspension. To suspend the third metallic standard lateral
furring strips to the third metallic vertical furring strips, each
third metallic vertical furring strips has brackets formed at
predetermined intervals. Each of the third metallic standard
lateral furring strips has through holes to engage a bracket at a
corresponding intersection to the third metallic vertical furring
strip. A though hole in the third metallic standard lateral furring
strip is engaged to a bracket of the third metallic vertical
furring strip and the upper inner edge of the through hole is hung
and suspended. To insert slidably the third metallic auxiliary
extension furring strip to the third metallic standard lateral
furring strip, the third metallic standard lateral furring strip
has a lateral cross section opened in the front side. The third
metallic auxiliary extension furring strip, which has the cross
section substantially in common with the third metallic standard
lateral furring strip, is loosely mounted squarely to the third
metallic standard lateral furring strip.
[0042] In the metallic wall exterior material base, to regulate a
sliding range of the third metallic auxiliary extension furring
strip to the third metallic standard lateral furring strip, a pair
of stoppers butts both ends in horizontal cross direction of a
bracket of the third metallic vertical furring strip. The bracket
protrudes toward the front side via a through hole for hanging in
the third metallic standard lateral furring strip and via a through
hole for sliding in the third metallic auxiliary extension furring
strip. The pair of stoppers is formed at both inner ends of the
through hole, for sliding, in horizontal direction at predetermined
intervals. (defined in claim 16)
[0043] The metallic wall exterior material base further comprises a
downward-pointing guide fin formed at the corresponding upper inner
edge and between a pair of stoppers. The pair of stoppers is
provided to a through hole for sliding in said third metallic
auxiliary extension furring strip. The guide fin contacts slidably
to an upper inner surface of a bracket in the third metallic
vertical furring strip. (defined in claim 17)
[0044] In the metallic wall exterior material base, the through
hole for sliding, formed in the third metallic auxiliary extension
furring strip, is rectangular in horizontal and longitudinal
direction. The guide fin is formed downwardly at the middle portion
of the upper inner edge in the through hole. A pair of stoppers is
formed at the lower portion on both the horizontal sides of the
through hole, such that each of the stoppers overlaps the lower
portion of a bracket of the third metallic vertical furring strip.

wall heat insulated building (defined in claims 15 to 18), the
lateral length of a wall exterior base used for an outer wall
exterior structure of a building can be adjusted easily. That is,
the lateral length of a combination of a third metallic vertical
furring strip, a third standard lateral furring strip, and a third
auxiliary extension furring strip can be adjusted easily. In other
words, the lateral length dealing with the outer corner or window
in a building can be easily adjusted. This feature allows the first
to third objects to be achieved certainly and effectively.

standard lateral rail for bridging to support the upper edge of an
engagement through hole in the fourth metallic standard lateral
rail. The bracket being supported on the front side of the
engagement through hole, whereby the fourth metallic short lateral
rail for bridging is coupled to the fourth metallic standard

inward and downward are formed in the bracket. The latch pieces can
be snapped into the latch hole formed in the fourth metallic
standard lateral rail. The upper edge of the engagement through
hole formed in the fourth metallic short lateral rail for bridging

engagement through hole formed in the fourth metallic short lateral
rail for bridging is slidably sandwiched between the bottom portion
of the fourth metallic vertical rail and the latch piece. (defined
in claim 25)
[0053] According to the metallic wall exterior base for an outer
wall heat insulated building (defined in claims 19 to 25), the
exterior base used covering the outer wall exterior structure of a
building can be constructed easily. This feature allows the first
to third objects to be achieved certainly and effectively.

BEST MODE FOR CARRYING OUT THE INVENTION
[0121] The present invention relates to a wall exterior structure
for an outer wall heat insulated building and a wall exterior base;
lateral furring strips for wall exterior installation and a method
for covering a wall using the lateral furring strips; and a
metallic exterior base and an outer wall using the metallic
exterior base. First, second, third and fourth embodiments of the
above-mentioned aspects will be explained blow in detail and
specifically by referring to the attached drawings.
[0122] The first, second third and fourth embodiments are explained
as follows:
[0123] In the first embodiment, a wall exterior structure including
a wall exterior base is generally explained as a most basic outer
wall exterior aspect of the present invention. Chiefly, the whole
structure including a vertical furring strip and a lateral furring
strip is shown in FIGS. 1 to 12.
[0124] The second and third embodiments relates to a wall exterior
structure including a wall exterior base and a metallic wall
exterior base, according to the present invention. In explanation,
a standard lateral furring strip (a second standard lateral furring
strip in the second embodiment and a third metallic standard
lateral furring step in the third embodiment) is used together with
an auxiliary extension furring strip (a combination of a second
standard lateral furring strip and a second auxiliary extension
furring step in a furring frame acting as an exterior base and a
combination of a third metallic standard lateral furring strip and
a third metallic auxiliary extension furring step in a furring
frame) to adjust the lateral width of a lateral furring strip. By
doing so, in a building construction, a variation in lateral width
of an outer corner or window in a structural frame can be
eliminated. Such structures are shown in FIGS. 1 to 35
(corresponding to the second embodiment) and FIGS. 36 to 50
(corresponding to the third embodiment), respectively.
[0125] In the fourth embodiment, the aspects of the embodiments 1
to 3 are aggregated wholly. A new wall exterior structure (using a
fourth vertical furring strip, a fourth standard length lateral
furring strip, and a fourth auxiliary extension furring strip) will
be explained by referring to FIGS. 51 to 64.
[0126] The configurations, functions and effects of the first to
fourth embodiments shown in FIGS. 1 to 64 are mutually overlapped
partially. However, to increase unambiguously the understanding of
respective configurations, the common drawings are not omitted.
[0127] In the first embodiment, reference numerals in single- to
double-digit number are attached in the corresponding drawings. In
the second embodiment, reference numerals in the 100 level are
attached except the reference numerals attached to the elements
corresponding to elements in the first embodiment. In the third
embodiment, reference numerals in the 200 level are attached,
except the reference numerals attached to the elements
corresponding to elements in the first embodiment. In the fourth
embodiment, reference numerals in 300 level are attached except the
reference numerals attached to the elements corresponding to
elements in the first embodiment. By doing so, explanation will be
omitted as much as possible and simplified. Thus, respective points
are clarified possibly.
Embodiment 1
[0128] First, according to the first embodiment, a wall exterior
structure and a wall exterior base, shown in FIGS. 1 to 12, will be
explained below.
[0129] FIGS. 1 to 12 show various elements in an outer wall heat
insulated building according to the first embodiment. FIG. 1 shows
a single family house to which an outer wall portion A is heat
insulated according to the wooden axial assembling construction
method. The single family house includes a structural base 1 having
its lower side embedded in the ground, a basic frame 2 fixed on the
structural base 1 and from which a weather board 3 is extended out
under a heat insulation structure, and plural main columns 4 and
plural studs 4a planted on the basic frame 2.
[0130] The outer wall portion A is formed of a structural panel 5
(being a structural frame in a broader sense) overlying a required
surface between the main column 4 and the stud 4a and an outer heat
insulation layer 6 disposed over the structural panel 5. An
exterior base 7 according to the present invention is disposed to
the outer surface of the structural panel 5.
[0131] In that case, a corrosion protection layer, e.g. a corrosion
resistant resin film (not shown), is coated on the back surface of
each vertical furring strip (or, each metallic vertical furring
strip) 8 of the exterior substrate 7 disposed on the outer heat
insulation layer 6 to avoid corrosion due to the direct contact of
the outer heat insulation layer and the vertical furring strip.
[0132] As shown in FIGS. 2 to 12, the exterior base 7 includes a
frame, which is formed of plural vertical furring strips 8 and
plural lateral furring strips 14. The vertical furring strips 8 are
arranged vertically and substantially in parallel over the surface
of the outer wall of the panel 5 at predetermined intervals. Each
vertical furring strip 8 is formed by shaping a metal plate, for
example, a high corrosive resistant metal plate such as steel
plate, galvanized steel plate, or galvanic steel plate, or aluminum
plate. The lateral furring strips 14 are arranged horizontally in
lattice from the outside and between the surfaces of the vertical
furring strips 8 at predetermined intervals. Particularly, the
lateral furring strips 14 are arranged and held in lattice with the
vertical furring strips 8 such that the space in the vertical
direction is relatively small. Each lateral furring strip 14 is
formed through shaping a metal plate of the same property.
[0133] Each vertical furring strip 8 may be subjected to, for
example, deformation processing such as roll shaping, press
shaping, and extrusion shaping. Relatively low erect rims 9, 9 are
formed along both longitudinal ends (or the right and left ends
vertically in installation state) of each vertical furring strip 8.
Vertical latch portions 8a are formed on the corresponding bottom
surfaces of intersections (to be described later) between rims 9
and 9 at predetermined intervals.
[0134] Similarly, each lateral furring strip 14 is subjected to the
deformation processing. Erect rims 15a and 15b, being relatively
high, are respectively formed at both edges in the longitudinal
direction (or the upper and lower edges in the lateral direction in
suspended state) of each lateral furring strip 14. The lateral
latch portions 14a respectively paired with the vertical latch
portions 8a are formed in the bottom corresponding to an
intersection (to be described later) between the rims 15a and 15a
at predetermined intervals.
[0135] An aspect between each vertical latch portion 8a and each
lateral latch portion 14a will be described below. Specifically, a
lateral latch portion 14a in the lateral furring strip 14 is
snapped and suspended into the corresponding vertical latch portion
8a in the vertical furring strip 8 disposed on the outer wall
surface of the panel 5. After the mounting, a grilled frame acting
as an exterior base 7 can be obtained where each vertical furring
strip 8 is disposed internally (on the panel 5) while each lateral
furring strip 14 is disposed externally (at the outer side).
[0136] In other words, as depicted in FIGS. 2 to 12, particularly,
in FIG. 8, each vertical furring strip 8 is a relatively long
furring strip, which has a width of 4 to 5 cm. Each of the erect
rims 9 and 9 has a height of 1 cm or less, e.g. a few millimeters.
In order to receive certainly and effectively a lateral furring
strip 14 at a corresponding position along the erect rims 9 and 9,
lateral receiving seats 10 and 10 are formed at predetermined
intervals. Each receiving seat 10 has a step 10a further protruded
upward from the edge by several mm.
[0137] The longitudinal length (in the vertical direction in a
mounted state) of each vertical furring strip 8 is for example, 45
to 50 cm, being a submultiple of the length referenced by a
building to be constructed. Nail holes 11 are opened in the middle
in width of the bottom of the vertical furring strip 8 at
predetermined intervals, e.g. at an interval of 15 cm. Latch
portions 8a are formed in the middle in width corresponding to the
portions (except the holes 11) intersected with the lateral furring
strips 14 at predetermined intervals, e.g. at an interval of 7 to 8
cm.
[0138] In this case, as understood from FIGS. 3 to 5, the vertical
latch portion 8a is formed by partially cutting and pulling up
relatively widely a nearly middle portion in width of a bottom of a
vertical furring strip 8. In the latch portion 8a, an erect piece
12 having a tongue piece 12a is formed at the upper edge thereof. A
latch tongue 13 is formed by partially opening downward the upper
portion of the erect piece 12.
[0139] In order to provide good latching condition effectively
after mounting, each vertical furring strip 8 is fixed to the panel
5 through the hole 11 by means of a fastener through the spring
fastener 19, which is inflated slightly outward to provide a
required resilient property. Here, each vertical furring strip 8 is
securely screwed to the panel 5 through the hole 11 by means of a
screw nail 20.
[0140] As described clearly later, the resilient force provided by
the spring fastener 19 works on the outer heat insulation layer 6
via each vertical furring strip 8 to be mounted. This means that
the outer heat insulation layer 6 is sandwiched with high pressure.
A hard synthetic resin material, with a relatively rich resilience,
e.g. nylon resin, is used as a resilient series material for the
spring fastener 19, can easily block the thermal conduction from a
metal vertical furring strip 8. By doing so, a suitable thermal
bridge measure is taken to the outer heat insulation layer 6.
[0141] As understood in FIGS. 2 to 12, particularly, FIG. 11, each
lateral furring strip 14 is a relatively long furring strip (in the
longitudinal direction in a sustained condition) having a width (in
horizontal direction in a sustained condition) of 4 to 5 cm. Each
of the upper erect rim 15a and the lower erect rim 15b is set to a
height of 1 cm or more. For example, with the erect rim of a height
of 2 cm or more, the hook/latch portion 16a, 16b is formed, by
folding back upward the edge of the erect rim 15a, 15b.
[0142] In that case, the exterior material 21 is hung and sustained
in the erect rims 15a, 15b and the hook/latch portion 16a, 16b, as
described later. Thus, it is desirable that the exterior material
21 hold relatively and somewhat loosely to the rims 15a, 15b and
the latch portions 16a, 16b to deal with possible vibrations and
other stresses.
[0143] The longitudinal length (in the horizontal direction in a
sustained condition) of each lateral furring strip 14 is, for
example, 1.8 to 2 m, being a sub-multiple of the length referenced
by a building to be constructed. Lateral latch portions 14,
respectively paired with vertical latch portions 8a, are arranged
in width on the bottom thereof at predetermined intervals, e.g. at
an interval of 50 cm. Similarly, the lateral latch portion 14a has
a lower through hole 17 formed by partially cutting away the lower
side (in a sustained condition) of the bottom, and a upper through
hole 18 formed by partially cutting away the upper portion (in a
sustained condition).
[0144] The width (in a suspended state) of the lower through hole
17 is set to be equal to or more than the width of the erect piece
12 in the vertical furring strip 8. The lower through hole 17
receives the whole of the erect piece 12. Similarly, the upper
through hole 18 has the size that can receive the latch tongue 13
of the vertical furring strip 8.
[0145] In mounting, the back surface of the lateral furring strip
14 is once contacted, at a slightly upper position, with the erect
rims 9, 9 of the vertical furring strip 8. Thus, the lateral
furring strip 14 having the lateral latch portion 14a is
temporarily placed over vertical furring strip 8 having the
vertical latch portion 8a. In the temporal placement, the bent edge
of the lower erect rim 15 of the lateral furring strip 14 is
pressed down until it butts against the steps 10a, 10b of the
lateral receiving seats 10, 10. The receiving erect piece 12 acting
as the vertical latch portion 8a of the vertical furring strip 8 is
received into the lower through hole 17 acting as the lateral latch
portion 14a of the lateral furring strip 14. Similarly, the latch
tongue 13 is resiliently press latched into the upper through hole
18. The latch portion 8a is snapped into the latch portion 14a. The
rigid, stable coupling can be obtained at the point where the
vertical furring strip 8 intersects with the lateral furring strip
14. Thus, a required exterior base 7 can be constructed.
[0146] The exterior base 7, where vertical furring strips 8 and
lateral furring strips 14 are arranged in lattice, can previously
prepared in parts in a factory and then be carried in a
construction site. Alternatively, the exterior base can be
completely assembled at a construction site. In either case, the
vertical furring strips 8 are arranged equally and horizontally
along the lateral furring strips 14. Each lateral furring strip 14
is latched via the latch portions 8a and 14a. However, the lateral
furring strip can deal with types of exterior materials 21
sustained in the lateral furring strip 14. The exterior materials
21, for example, exterior tiles, can be used corresponding to the
number of intervals of latch portions 8a in a vertical furring
strip 8. Moreover, when the exterior material 21 is, for example,
an exterior panel, exterior tiles can be used corresponding to the
number of intervals of the latch portions 8a in the vertical
furring strip 8, which is smaller in number than intervals
according to positions corresponding to the height of the exterior
panel.
[0147] Moreover, the exterior base 7 is fixed to the outer heat
insulation layer 6 while the vertical furring strips 8 are disposed
internally (or on the side of the panel 5 and the outer heat
insulation layer 6) and the lateral furring strips 14 are disposed
externally (on the outside). The vertical furring strips 8 can
press the outer heat insulation layer 6 against the panel 5.
[0148] In the exterior base 7, as seen in FIG. 12, exterior
materials, herein, exterior tiles 21, are hung and sustained to the
upper and lower latch portions 16a and 16b, each being bent upward,
in the lateral furring strip 14. In this case, joints in vertical
direction of the joints 22 formed between exterior tiles 21 are
previously filled with backup materials and thus being cement
plastered. However, as to joints in horizontal direction, the
bottom itself of the lateral furring strip 14 can be used as a
backup material.
[0149] A heat insulation panel of closed-cell foamed phenol series
resin and having high heat insulation performance, for example, is
generally used for the heat insulation layer 6. However, because an
acid catalyst is used for the phenol series resin, the outer heat
insulation layer 6 exhibits acid. Acid tends to corrode easily the
metallic vertical furring strips 8, thus resulting in a failure of
the durability of the exterior base 7.
[0150] However, in the first embodiment, a corrosive protection
layer of a corrosive resistant resin film is coated on the back
surface of the vertical furring strip 8. By doing so, an harmful
effect due to the use of the metallic vertical furring strip 8 can
be avoided certainly and previously so that a high heat insulation
performance can be easily obtained.
[0151] The exterior base 7 is disposed on the outside of the outer
heat insulation layer 6. Thus, a desired ventilation space 23,
which has a relatively narrow gap, can be defined between the outer
heat insulation layer 6 and an exterior material, e.g. an exterior
title 21, as shown in FIGS. 11 and 12.
[0152] In the first embodiment, the ventilation space 23 can be set
to be a gap of about 1 cm or less, particularly, about 5 mm. When
the first embodiment is assembled using common metal fittings, the
gap can be reduced to about 1/4, compared with a gap of about 2 cm
in the conventional structure. As a result, the difference between
the gap and a total length of about 7 cm of the exterior components
of a building, that is, redundant portion of about 1.5 cm, can be
used for the outer heat insulation layer 6. Thus, the outer heat
insulation layer 6 can be thickened to about 6.5 cm from 3 to 5 cm
in the conventional structure so that the heat insulation
performance can be improved dramatically.
Second Embodiment
[0153] Next, a wall exterior structure embedding the second
embodiment of the present invention and a lateral furring strip for
wall exterior including the wall exterior base will be explained by
referring to FIG. 13 to FIG. 35.
[0154] The second embodiment belongs to the same line as the first
embodiment and has so much in common with the first embodiment.
Hence, the explanation becomes complicated. In the second
embodiments shown in FIGS. 13 to 35, like numerals are attached to
the same elements as those in the first embodiment. Thus, the
explanation is simplified. The number of 100 is added to the
corresponding numerals of main elements.
[0155] In the third embodiment, like numerals are attached to the
same elements as elements in the first and third embodiments and
the explanation is simplified. The number of 200 is added to the
corresponding numerals of main elements.
[0156] In the second embodiment shows FIGS. 13 to 35, a metallic
lateral furring strip frame 100a is formed of plural second
vertical furring strips 124 (hereinafter merely referred to as
"vertical furring strips 124"), plural second standard lateral
furring strips 124 (hereinafter merely referred to as "standard
lateral furring strips 101"), and a second auxiliary extension
furring strip 102 (hereinafter merely referred to as "auxiliary
extension furring strip 102"). Each second vertical furring strip
124 corresponds to the vertical furring strip 8 acting as the
exterior base 100. Each second vertical standard lateral furring
strip 101 is suspended to each vertical furring strip 124 and is
attached to the exterior material 21. Each second auxiliary
extension furring strip 102 can be selectively inserted slidably
into the standard lateral furring strip 101 to adjust the
longitudinal length (corresponding to the horizontal width in a
mounted state) of the standard lateral furring strip 102.
[0157] Both the vertical furring strips 124 and the standard
lateral furring strips 101 are assembled in a lattice form. The
vertical furring strips 124 are arranged vertically and in parallel
at relatively broad intervals. The standard lateral furring strips
101 are arranged horizontally and in parallel at relatively narrow
intervals. The auxiliary extension furring strip 102 is slidably
inserted longitudinally into the standard lateral furring strip 101
to obtain the lateral furring strip frame 100a.
[0158] Since each standard lateral furring strip 101 has its fixed
length, the suspension range of the exterior material 21 (the
suspension effective width in a mounted state) is specified. This
cannot deal with the width of an outer corner or window, varied at
construction sites.
[0159] In the lateral furring strip frame 100a of the second
embodiment, the auxiliary extension furring strip 102 is slidably
protruded out from the end of the standard lateral furring strip
101. This operation allows the total length of both furring strips
or the suspension effective width of the lateral furring strip
frame 100a to be adjusted variably.
Third Embodiment
[0160] Next, a wall exterior structure according to the third
embodiment of the present invention and a wall exterior base
thereof will be explained by referring to FIGS. 36 to 50.
[0161] In the third embodiment shows in FIGS. 36 to 50, a metallic
rail unit frame 200a is formed of fourth vertical rails (vertical
furring strips) 201 (hereinafter merely referred to as "vertical
rails 201"), plural third standard lateral rails for unit formation
(unit formation standard lateral furring strips) 202 (hereinafter
merely referred to as "standard lateral furring strips 202 for unit
formation"), plural third bridge short lateral rails (short lateral
furring strips for bridging) (hereinafter merely referred to as
"short lateral rails 203 for bridging), and plural third extension
adjustment lateral rails (lateral furring strips for extension
adjustment) 204 (merely referred to as "lateral rails 204 for
extension adjustment"). Each fourth vertical rail 201 corresponds
to the vertical furring strip 8. Each third standard lateral
furring strip 202 is suspended to the vertical rail 201 and is
attached to the exterior material 21. Each third short lateral rail
203 is selectively mounted to the standard lateral rail 202. Each
fourth lateral rail 204 is selectively suspended to the short
lateral rail 203 and is sidable longitudinally (horizontally in a
mounted state).
[0162] The vertical rails 201 and the standard lateral rails 202
are combined in a lattice state to construct a lattice rail unit
frame 200a. The vertical rails 201 are arranged vertically and in
parallel at relatively broad intervals. The standard lateral rails
202 are arranged horizontally and in parallel at relatively narrow
intervals. That is, the standard lateral rails 202 are suspended
and attached to the vertical rails 201 to assemble the rail unit
frame 200a.
[0163] In the third embodiment, the lateral rail 204, engaged to
the standard lateral rail 202 and the short lateral rail 203 for
bridging, is slidably extended out from the end of the short
lateral rail 203. The total length of both the rails 203 and 204,
or the suspension effective width of the rail unit frame 200a
itself, can be adjusted variably.
[0164] That is, the short lateral rail 203, attached to the
standard lateral rail 202, can reserve the longitudinal length or
horizontal length of the standard lateral rail 202 to some
extent.
[0165] In other words, the end (here, the right end) of the
standard lateral rail 202 can be protruded out to a required
length.
[0166] Therefore, in the lateral rail 212, the total length in the
horizontal direction of the standard lateral rail 210 and the short
lateral rail 211 or the entire length in the horizontal direction
of the rail unit frame 201 can be arbitrarily adjusted. This can
easily compensate the length lacking due to outer corners and
windows.
Forth Embodiment
[0167] A wall exterior structure according to the fourth embodiment
of the present invention and a wall exterior base thereof will be
explained by referring to FIGS. 51 to 64.
[0168] In the fourth embodiment shown in FIGS. 51 to 64, a rail
unit frame 301 in lattice constructing an exterior base includes
plural fourth metallic lateral rails (lateral furring strips) 302
(hereinafter merely referred to as "lateral rails 302"), plural
fourth metallic standard lateral rails (standard lateral furring
strips) 310 (hereinafter merely referred to as "standard lateral
rails 310"), plural fourth metallic short lateral rails for
bridging (short lateral furring strips for bridging) 311
(hereinafter merely referred to as "short lateral rails 311 for
bridging"), and plural fourth metallic lateral rails for extension
adjustment (lateral furring steps for extension adjustment) 312
(hereinafter merely referred to as "lateral rails 311 for extension
adjustment").
[0169] The vertical rails 302 and the standard lateral rails 310
are arranged in lattice. The vertical rails 302 are arranged
vertically and in parallel at relatively broad intervals. The
standard lateral rails are arranged horizontally and in parallel at
relatively narrow intervals. In this case, the lattice-like rail
unit frame 301 is constructed as shown in FIGS. 51 to 53 and FIGS.
54 and 55.
[0170] As shown in FIGS. 56 to 61 and FIG. 64, the short lateral
rail 311 bridges the standard lateral rails 312. Similarly, as
shown in FIGS. 62 and 63, the lateral rail 312 extends to adjust
the finish width of each standard lateral rail 310 (the detailed
structure will be described later).
[0171] The standard lateral rail 310, the short lateral rail 311,
and the lateral rail 312, (to be described later in detail), are
used to suspend the exterior material 323.
[0172] Each of the rails 302, 310, 311, and 312 is made of a metal,
e.g. a metal steel plate having good corrosion resistance, such as
galvanized steel plate, galvanic steel plate, which is subjected to
deformation processing such as roll forming, shaping, and press
shaping.
[0173] Each of the rails 302, 310, and 311 may be a standard rail
set to a required length. As shown in FIGS. 54 to 56, the vertical
rail 302, for example, has a base plate 303 having through holes
304, erect rims 305 and 305, and rail seats 306 and 306. The
through holes 304 are arranged at a predetermined interval of 15 cm
and allow passage of screws or screwed nails 322, which securely
fix rails to the structural frame or columns in the fourth
embodiment. Each of the erect rims 305 and 305 is formed through
bending outward in low level both ends in width of the base plate
303 to define a ventilation space (to be described later). The rail
seats 306 and 306 are formed in the same plane longitudinally along
the rims 305, 305 to receive the standard lateral rail 310.
[0174] Here, each of the rails 310, 311 and 32 has substantially
same configuration as that in the third embodiment. In the fourth
embodiment shown in FIGS. 51 to 64, reference numerals in the third
embodiment are represented by the order of 300 (for example, the
standard lateral rail 210 is represented as the standard lateral
rail 310). The function and effect of the elements are
substantially identical and hence the duplicated explanation will
be omitted.
