[57] 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 -comer or wall section spaces to receive reentorcing 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 comer construction 11 is shown and also wall panel constructions l2 and 13 extending from the comer 11 at right angles to each other. An intermediate column and wall sheath spacer construction 14 is shown at the right of the comer 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 caterrninous 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 l9, 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 comer 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 210 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 280 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 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 vertically spaced apart in both legs 29a and 29b thereof.

The assembly of the comer 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

260 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 comer column structure 11 and the nearest such column structure 14.

After the comer 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 ob tained.

Referring now to FIGS. 6-1 1, there will be described modified forms of construction for the comer and noncomer 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 400. 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 410 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 400 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 440 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 440 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 450 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 450 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 440 of the first connector 44. This enables the

ribs

45d and 45e to lock in place intermediate the

ribs

44d and 44a, 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. 1 1. 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 Me 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 comer 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 530 which extend in the direction of the corner of the wall structure. The comer 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 540 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 comer 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 comer 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 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 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 comer 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 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 comer 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 comer on a course of substantially 45 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 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 680 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 pans 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 throughholes 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 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 comer 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 630 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 afiixed 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.
