PLATE CONNECTED STRUCTURAL MEMBER CONSTRUCTION FOR BUILDING
WALLS
Abstract
The invention discloses channel members, as the broadest common
element, with various adaptions made with relation to, or in the
channel members whereby other members may be latchable engaged
therewith, as the channels are in place in wall constructions,
whereby the channels may segregate building corner or wall section
spaces to receive reenforcing concrete therein. A first presented
form of the invention relied upon slots and pins in respective
interfitting members to segregate the corner or wall spaces into
which the reenforcing concrete was poured. In a later presented
form of the invention reliance was made upon inter-fitting teeth,
with flexibility of tooth engagement being accomplished by making
one tooth forming member of plastic with enough resilience to give
amply to permit teeth interfitment. In a preferred form of the
invention, now presented the members to be interfitted provide
respectively vertically disposed holes in one member, as the
channel, to receive therethrough latch providing extensions which
are spring urged into latching position after passing through the
aforesaid holes.

DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS
Referring now in detail to the drawings of structures now pending,
in which like reference numerals are applied to like elements in
the various views, a building construction 10 is shown in FIGS. 1
and 2 in which a corner construction 11 is shown and also wall
panel constructions 12 and 13 extending from the corner 11 at right
angles to each other. An intermediate column and wall sheath spacer
construction 14 is shown at the right of the corner 11 in FIG. 1
and to the left of the corner 11 in FIG. 2, which is illustrative
of the columnar construction comprising an important portion of
this invention.
In detail, a column 14 is shown as comprising upstanding channels
15a, 15b with respective pairs of channel flanges 16a, 16b in outer
edge face abutment. Outer and inner upstanding connector plates
17a, 17b are shown disposed against the inner faces of the outer
channel flanges 16a and 16b and against the inner faces of the
inner channel flanges 16a and 16b, with the flanges 16b being
provided with latch bolts or rivets 18 with heads 18a disposed at a
spaced distance inwardly from the inner faces of the respective
channel flanges 16b, such spaced distance being a distance slightly
greater than the thickness of the plates 17a and 17b .
In fabrication, the channel 15b is first placed in proper upright
position on a conventional runner or slab 19, as shown in FIG. 5,
with the bolts or rivets 18 vertically spaced along flanges 16b at
predetermined distances apart. Then the channel 15a (with the left
outer faces of the connector plates 17a and 17b secured to the
respective inner faces of the channel flanges 16a, as by gluing,
welding, bolting, or by any appropriate means) is maneuvered to
latch the connector plates 17a and 17b, having therein the
appropriately spaced latching slots 20 shown in FIG. 3 over the
aforesaid bolts or rivets 18 which extend inwardly from the flanges
16b .
With the opposed or abutting channels 15a and 15b thus positioned
and latched together, the inner wall sheaths 21a and outer wall
sheaths 21b are caterminous with and disposed against and secured
to the outer faces of the channel flanges 16a and 16b of spaced
apart aligned columns 14 whereby the wall sheaths 21a and 21b are
properly longitudinally aligned and transversely spaced apart. As
shown in cross-section in FIG. 5, a wall construction 12 or 13,
comprised of wall sheaths 21a and 21b, thus spaced apart, fits at
bottom into rectangularly cross-sectioned groove means 22 in a
concrete slab or runner 19, concrete 23 having been poured to a
depth between the wall sheaths or within the column 14 to anchor a
wall 12 or 13 to the base or slab 19.
The corner construction 11, as shown in FIGS. 1 and 2, includes an
outer corner angle member 24 which may be of the same construction
material as the walls 21a and 21b, or of any suitable light
material. Then inwardly of the angle member 24, in the finally
assembled views of FIGS. 1 and 2, a structural angle 25 is shown,
such angle 25 have appropriately, vertically spaced apart bolts or
rivets 18 which extend inwardly from the inner faces of the angle
legs 25a and 25b . Angle 25 is secured to angle member 24 by
gluing, welding, or the like. Also, the corner construction 11
includes a channel 26a across the wall construction 12 at ninety
degrees to the wall construction 13. Each of the channels 26a and
26b has vertically spaced apart inwardly extending studs 18b
mounted on the flange 27a thereof.
A connector plate 28a is shown in FIGS. 1 and 2 as having its left,
outer face disposed against and secured to the inner face of the
flange 27b of the channel 26a, such connector plate having
vertically spaced apart slots 30 in the right-hand side thereof. As
indicated in FIG. 4, the slots 30 each have an enlarged upper
portion 30a and a smaller, lower portion 30b, for purposes to be
hereinbelow described. Also, a second connector plate 28b is shown
in FIGS. 1 and 2 as having its right, outer face disposed against
and secured to the inner face of the flange 27b of the channel 26b,
such plate having vertically spaced apart slots 30, as hereinabove
described, in the left-hand side thereof as viewed in FIG. 1. A
further angle 29 is shown in FIGS. 1 and 2 as having holes 35
vertically spaced apart in both legs 29a and 29b thereof.
The assembly of the corner construction 11 is accomplished first by
disposing channels 26a and 26b in upright positions in the relative
plan positions indicated in FIG. 1 and best visualized from FIG. 2.
Then the inner angle 29 is placed in proximity to the respective
inner flanges 27a of the channels 26a and 26b and in a manner such
that the the oversized holes 35 receive the studs 18b therein.
Next, with the connector plates 28a and 28b in established contact
with the channel flanges 27b of the respective channels 26a and
26b, the angle 25 is moved toward the position shown in FIG. 1. As
best visualized in FIG. 2, the bolt heads 18a are passed through
the larger, uppermost portions 30a of the slots 30 in the connector
plates 28a and 28b and then lowered into the smaller, lower
portions 30b thereof.
As indicated in FIG. 2, spacer members 32 (and 32a if desired) may
be located intermediate the column structures 14 or between the
corner column structure 11 and the nearest such column structure
14.
After the corner structure 11 and the wall structures 12 and 13
have been assembled and erected, the centers of the column
structures 14 (the regions enclosed by each pair of channel members
15a and 15b ) and the center of the corner column structure 11 (the
region enclosed by channel members 26a and 26b and angle member 25)
are preferably filled with a filler material such as concrete. Such
concrete is indicated by reference numeral 33 in FIG. 2. After the
concrete hardens, it seals the joint defined by the structural
members forming the column structures. Such concrete also provides
a weight bearing columnar structure for supporting the next floor
level or the roof or the like of the building.
The column structures 11 and 14 are particularly useful for
interconnecting prefabricated wall panels. Considering, for
example, the column structure 14 shown in FIG. 2, the wall panel
structure connected to the channel 15a can be prefabricated at a
factory location with the channel 15a and connector plates 17a and
17b mounted in the left-hand end thereof. In a similar manner, the
wall panel structure connected to the right-hand channel 15b can be
prefabricated at the factory with the channel 15b and latch bolts
18 mounted in the left-hand end thereof. Thereafter, when the wall
panels arrive at the building site, they can be quickly connected
together by lowering the wall panel having the connector plates 17a
and 17b so as to cause the latch bolts 18 to move upwardly into the
latching slots 20 in such connector plates 17a and 17b . After the
concrete is poured into the center space intermediate the channels
15a and 15b and allowed to harden, a relatively permanent
connection of the wall panels is obtained.
Referring now to FIGS. 6-11, there will be described modified forms
of construction for the corner and non-corner column structures.
Considering first FIGS. 7 and 8, there is shown in a disengaged or
disconnected manner the two parts which, when connected together,
form a structural column which is located at an intermediate point
in a building wall. This column structure includes first and second
upstanding structural members 40 and 41. Member 40 is a structural
channel member having a web 40a, an inner flange 40b, and an outer
flange 40c. The second structural member 41 is also a structural
channel member having a web 41a, an inner flange 41b, and an outer
flange 41c . Channel member 40 is mounted in the right-hand end of
a wall panel 42 having wall sheaths 42a and 42b . The second
channel member 41, on the other hand, is mounted in the left-hand
end of a wall panel 43 having wall sheaths 43a and 43b . When the
wall panels 42 and 43 are connected together, the inner flanges 40b
and 41b abut one another. Similarly, the outer flanges 40c and 41c
likewise abut one another.
The column construction of FIGS. 7 and 8 further includes first
connector means 44 mounted on the first structural channel member
40 between the flanges 40b and 40c thereof. This connector means or
connector 44 is a generally U-shaped channel member having a web
44a secured to the web 40a of the channel 40 and having a pair of
legs 44b and 44c which constitute ribbed elements which extend
toward the second structural channel member 41. The ribs are
provided by cutting series of longitudinally extending notches in
the outer surfaces of the legs 44b and 44c . The notches or ribs on
leg 44b are indicated at 44d . The notches or ribs on leg 44c are
indicated at 44e . As can be seen from the elevational type view of
FIG. 9, these ribs 44d and 44e run at right angles to the direction
of extension of the legs 44b and 44c .
The column structure of FIGS. 7 and 8 also includes second
connector means 45 mounted on the second structural channel member
41 between the flanges 41b and 41c thereof. This second connection
means or connector 45 is also a generally or approximately U-shaped
channel member. As such, the connector 45 includes a web 45a which
is secured to the web 41a of the structural channel 41 and a pair
of legs 45b and 45c which constitute ribbed elements which extend
toward the first structural channel 40. The ribs are indicated at
45d and 45e . These ribs 45d and 45e are formed by cutting series
of longitudinally extending notches in the inner surfaces of the
legs 45b and 45c . These notches or ribs 45d and 45e run at right
angles to the direction of extension of the legs 45b and 45c .
The second connector 45 is sized so that the legs 45b and 45c
thereof will fit snugly over the legs 44b and 44c of the first
connector 44. This enables the ribs 45d and 45e to lock in place
intermediate the ribs 44d and 44e, respectively, of the first
connector 44. This locked condition is shown for a portion of the
ribs 44d and 45d in the fragmentary view of FIG. 11. The second
connector 45 is of a resilient construction for enabling the ribs
45d and 45e thereof to slide over and then lock in place
intermediate the ribs 44d and 44e of the first connector 44. In a
preferred embodiment, the first connector 44 is made of metal and
the second connector 45 is made of a resilient plastic
material.
Connector 44 is secured to the structural channel 40 by a series of
vertically spaced apart bolts or rivets 46. The second connector 45
is similarly secured to the second structural channel 41 by a
series of vertically spaced apart bolts or rivets 47.
Considering now the modified corner column construction of FIG. 6,
such construction is generally indicated at 50 and is used for
forming a corner joint between a pair of wall panels 51 and 52
extending at right angles to one another. The corner structure 50
includes a first upstanding structural channel member 53 mounted in
the end of the wall panel 51 and having a web 53a and a pair of
flanges 53b and 53c which extend in the direction of the corner of
the wall structure. The corner structure 50 also includes a second
structural channel member 54 mounted in the end of the second wall
panel 52 and having a web 54a and a pair of flanges 54b and 54c
which extends in the direction of the desired corner joint. Secured
to the first structural channel 53 is first connector 55 in the
form of an angle member having a ribbed or notched leg 55a
extending in the direction of the common corner location. Secured
to the second structural channel 54 is a second connector 56 in the
form of a channel-shaped member having ribbed or notched legs 56a
and 56b which extend in the direction of the common corner
location.
The corner structure 50 further includes an upstanding structure
angle member 57 having legs 57a and 57b which adjoin the outer
flanges 53c and 54c of the channels 54 and 54, respectively.
Secured to the leg 57a is a ribbed element 58 in the form of a bent
plate which extends the vertical length of the angle 57. The ribs
or notches 58a of the element 58 engage the ribs or notches on the
connector 55 in an overlapping and interlocking manner. Secured to
the other leg 57b of the angle 57 is a second ribbed element 59 in
the form of a bent plate which runs the vertical length of the
angle 57. The longitudinally extending ribs or notches 59a of the
bent plate 59 engage the ribs or notches on the outer surface of
the leg 56a of the second connector 56 in an overlapping and
interlocking manner.
The corner structure 50 also includes an inner angle member 60,
having one leg 60a secured to the inner flange 53b of the first
structural channel 53. The other leg 60b of the angle member 60
includes a ribbed or notched portion for engaging the ribs or
notches on the leg 56b of the connector 56.
In a preferred embodiment of the invention, the connectors 55 and
56 are constructed of a resilient plastic material. These
connectors 55 and 56 are secured to their respective structural
channels 53 and 54 by means of bolts, rivets, or any other suitable
securing mechanism or agent.
The corner structure 50 is assembled by first positioning the outer
angle 57 so that the ribs 58a engage the ribs or connector leg 55a
and then moving the second well panel 52 into position such that
the connector 56 is inserted between the bent plate 59 and the
inner angle member 60.
After the various well panels have been erected and various column
structure connectors have been interconnected, the interiors or
centers of the various FIG. 6-11 type column structures are filled
with an appropriate load sustaining material such as concrete.
If desired, some of the teeth forming the ribs on any one or more
of connectors 44, 45, 55, and 56 and members 58, 59, and 60 may be
of a rounded character instead of a pointed character. Considering
connector 44, for example, the outer tips of all but the right-hand
most ones of the teeth 44d and 44e may be rounded off, the
right-hand most tooth in each set continuing to have a pointed tip
as shown.
In a now preferred, and newly presented form of the invention, a
corner construction is first presented in FIG. 12, with parallel
wall sections or plates 61a, 61b extending at right angles to
parallel extending wall sections or plates 62a, 62b, the inner side
face of the end portion of the plate 62b abutting across the end or
edge surface of the inner plate 61b . A light channel 63a is shown
affixed between the ends of the parallel plates 61a, 61b, thus with
flanges in abutment with the inner, end surface portions of the
respective plates 61a, 61b, and a corresponding light channel 63b
is shown affixed between the ends of the parallel plates 62a, 62b,
thus with flanges in abutment with the inner, end surface portions
of the respective plates 62a, 62b.
The channels 63a, 63b, have vertically spaced apart, rectangular
shaped holes 64a, 64b, provided therein, correspondingly as
indicated in FIG. 17, with the holes 64a to receive therethrough
latch carrying lugs 65, provided correspondingly vertically spaced
apart along the outer edges of a corner inner angle 66, the angle
66 being moved into the open corner on a course of substantially
45.degree. , whereby the inner faces of the inner flanges of the
respective channels 63a, 63b, guide the angle into the position
shown in FIG. 12, as the latches 67 carried by the angle lugs 65
are passed through the holes 64a, the latches 67 then latching as
will be hereinbelow described.
In detail each latch 67 comprises two opposed channel sections 68a,
68b, with the channel 68b having a web shorter than the web of the
channel section 68a by at least two flange thickness, whereby the
channels may fit one within the other in folded position, FIG. 17.
The channels are drilled through at their ends outermost from the
angle 66 which provides the lugs 65. The drilled through flanges of
the latch channels 68a, 68b. are then fitted to receive the opposed
ends of a tee member 69 therethrough, vertically opposed springs
70a, 70b, having inner ends anchored to the central leg of the tee
member 69, with the coils of the springs 70a, 70b, being wound
respectively upwardly and downwardly about the respective upper and
lower parts of the tee cross-member, and with the respective upper
and lower ends of the springs 70a, 70b, extending substantially
perpendicularly from the cross-member parts to form torsion spring
urging members 71a, 71b, against the inner surfaces of the
respective inner faces of the webs of the channel sections 68a,
68b, near the respective flanges thereof.
The inner end 72 of the central leg of the tee member 69 is
threaded for a pre-determined length to be threadedly received into
a threaded bore provided centrally into the outer face of the lug
65, FIG. 16. Thus each latch 67 may be threadably engaged by means
of its tee member 69 to a pre-determined depth in its respective
lug or carrier 65. Thus when a lug 65 carrying its latch 67, folded
to pass through its respective channel hole 64a or 64b, passes
through the hole, the torsion spring ends 71a, 71b, urge their
respective latch channels 68a, 68b outwardly, so that the beveled
ends 73 of the latch channels may latch in flush abutment with the
outer face of the respective wall channels 63a or 63b .
A specially constructed angle 74, FIG. 12, provides lugs 65 that
carry corresponding latches 67, passed through holes 64b in the
respective channels 63a, 63b, the lugs and holes being of size and
provided at elevations in the respective angle 66 and end channel
63a, 63b, in correspondence with the respective lugs 65 of the
angle 66 and with the respective channel holes 64a . This angle 74
has the outer thickness of the inner portions of its legs 74a, 74b,
relieved for the thickness and width of the respective wall end
channels 63a, 63b, and the inner faces of the flanges of these
respective channels 63a, 63b, serve to guide the special angle 74
as it is brought into the corner on substantially a 45.degree.
course, to enclose the corner space that is later to be filled, as
with concrete. Finally, as indicated in FIG. 12, a corner angle 75
may be installed upon the inner corner angle 74 to complete the
corner flush with the wall plates 61a, 62a . Optionally, the corner
angles 74 and 75 may be provided as an integrated structure.
As a variation of the latch forms shown in FIGS. 12-17, a latch is
shown in FIG. 18 in which the member that ordinarily would provide
the projection or lug to threadably receive the central member of
the tee, is a thin plate 76, whereby the central member of the tee
77 is a thin bar 78 that may be connected to the plate 76, as by
rivets or screws 79. In this case the width of the holes or
openings through the channel members which are to receive this type
of latches therethrough must be just slightly greater than the
thickness of the plate 76 plus the thickness of the bar 78, plus
two latch channel web thicknesses, the notch or hole height and all
other features of the latch construction being the same as for the
latch hereinabove described in relation to FIGS. 12-17.
Making reference now to FIGS. 13 and 14, the operation of the form
of the invention herein described with relation to FIGS. 12-17, is
indicated as employed to close off a section or columnar space
along a wall indicated as comprised of the plates 61c, 61d, with a
light channel 63c shown affixed between the end portions of the
plates 61c, 61d, facing outwardly, and correspondingly having
vertically aligned holes 64c, 64d therein.
In this case a section of the wall to be adjoined in abutment with
the wall defined by and between the plates 61c, 61d, is indicated
as comprised of plates 61e, 61f, with end portions having a channel
63d thereinbetween the plate end portions, the channel 63d facing
outwardly, with the channel 63d providing latches 67 for the lugs
65 provided by plates 79a, 79b which are affixed to the inner faces
of the flanges of the aforesaid channel 63d.
Thus with the latches 67 assembled to the projections or lugs 65,
the ends 80a, 80b may be peened to complete the latch assembly
correspondingly as in the case of the latches hereinabove described
with relation to FIGS. 12 and 15-17, inclusive, also in the case of
the latch 67a, FIGS. 13 and 14. Thus, when the wall section 61e,
61f, is brought with the plate end faces thereof to abut the end
faces of the respective plates 61c, 61d, the latches 67 pass
through the respective holes therefor and are spring urged latched
to latch the respective wall sections 61c, 61d, and 61e, 61f,
together to provide a space thereinbetween into which concrete can
be poured to provide a columnar reenforcing structure along the
walls, and entirely concealed therewithin.
While there have been described what are at present considered to
be preferred embodiments of this invention, it will be obvious to
those skilled in the art that various changes and modifications may
be made therein without departing from the invention, and it is,
therefore, intended to cover all such changes and modifications as
fall within the true spirit and scope of the invention.
