Prefabricated built-up panel units may utilize the metal structural panel units as body reinforcement for efficient load bearing utility such as in prefabricated walls, partitions, roof decking, floor decking, etc.

12 Claims, 6 Drawing Figures LIGHT WEIGHT LOAD BEARING METAL STRUCTURAL PANEL The present invention relates to improvements in structural panel unit structures, and is more particularly concerned with light weight units of this type formed from sheet metal.

Numerous and varied forms and arrangements of reinforcement have been provided for prefabricated structural panels and other structural units. Such reinforcements have been useful only as reinforcement and have not been useable as studding or framing as such. In other words, it has been necessary to incorporate the reinforcement in a built-up panel or other structural shape with other materials. Insofar as I am presently informed, no one has heretofore provided a light weight load bearing metal structural panel which is adapted either to serve as building framing or studding to receive any desired wall covering or sheathing thereon, or to serve as a body reinforcement'for a built-up or prefabricated panel. It is to the attainment of such a structure that the present invention is directed.

An important object of the invention is to provide a new and improved light weight structural panel unit formed from sheet metal and possessed of great compression strength and resistance to applied forces in its plane as well as across its plane and which may serve by itself as building wall framing or studding or may be embedded in a built-up prefabricated panel constructron.

Another object of the invention is to provide a low cost light weight structural panel unit formed in part of expanded metal sections. 7

A further object of the invention is to provide a new and improved load bearing sheet metal panel unit.

Still another object of the invention is to provide a new and improved prefabricated panel unit having unique load sustaining body reinforcement.

Other objects, features and advantages of the invention will be readily apparent from the following description of certain preferred embodiments thereof, taken in conjunction with the accompanying drawing although variations and modifications may be effected without departing from the spirit and scope of the novel concepts embodied in the disclosure, and in which:

FIG. 1 is an isometric fragmentary, exploded detail view showing a representative form of a light weight high compression strength load bearing metal structural panel unit embodying features of the invention;

FIG. 2 is a fragmental isometric view showing one use of the panel unit of FIG. 1.

FIG. 3 is an enlarged fragmentary sectional detail view taken substantially along the line III-III of FIG. 2.

FIG, 4 is a fragmentary isometric view showing a modification in the structural panel unit.

FIG. 5 is a transverse sectional detail view showing another use for the panel unit.

FIG. 6 is a fragmentary transverse sectional view showing still another use for the structural panel unit.

In a representative form of light weight high compression strength load bearing metal structural panel unit 10 embodying features of the invention, as shown in FIG. 1, principal elements comprised spaced coextensive generally U-shaped load bearing side channel bars 11 provided with Web portions 12 defining side edges of the panel unit and having solid marginal substantial width bearing and nailing flanges 13 extending inwardly of the unit at opposite face planes of the unit. An open mesh body connects certain of the flanges 13 of the side bars 11 in the unit 10 and maintains the side bars in substantially fixed spaced relation.

In the illustrated instance the unit 10 is of a width wherein a load bearing intermediate bar 15 is desirably located midway between and coextensive with the side bars 11. In one preferred construction, the intermediate bar 15 is of rugged channel beam structure comprising a pair of spaced apart oppositely extending coplanar solid bearing and nailing flanges 17 to which respective sections 18 of the body 14 are connected. The flanges 17 are substantially the same width as and lie in a face plane with those flanges 13 of the side bars 11 to which the sections 18 are also connected. Extending angularly from the flanges 17 in spaced apart relation are side wall flanges 19 ofthe bar 15 which join a connecting solid bearing and nailing web flange 20 desirably of the same width as and lying in a plane with the side bar flanges 13 at the opposite face ofthe panel unit 10 from the flanges 17. It will thus be apparent that the panel unit 10 comprises the rigid side bars 11 and the rigid intermediate bar 15, all cooperating to provide an efficient load bearing structure in the plane thereof considered longitudinally with respect to the bars 11 and 15 and wherein great resistance is provided against not only compression but also tension loads transverse to the axes of the several bars of the unit.

Low cost, efficient construction of the panel unit 10 is enhanced by making the entire unit from a single sheet of suitable gauge metal and with the body sections 18 of open mesh structure, preferably provided by the expanded metal technique wherein staggered longitudinal slits are made in the sheet metal in an area which is narrower than intended for the completed panel, and the metal than stretched laterally to expand the slits whereby a uniform pattern of mesh openings 21 and integral mutually interconnecting portions 22 are integrally connected to the bar flanges 13 and 17. By preference, also, the side wall flanges 19 of the intermediate bar 15 are provided with respective expanded sections 23 preferably extending throughout the length of these flanges 19. It will be observed that substantial width portions of the side walls 19 angularly joining the flanges 17 and the web 20 are solid and unexpanded, whereby longitudinal load bearing integrity of the bar 15 is preserved. If preferred, although not shown, the web portions 12 of the side bars 11 may also be formed with expanded metal sections similarly as the expanded metal sections 23.

In one desirable embodiment, the panel unit 10 may be adapted for building wall or partition use, being generally conformed to conventional dimensions for that purpose thus, for example, the panel unit may be of an over-all width of four feet, with the flanges 13 of the side bars 11 of about 1 /2 inch width and 2 inch depth, with the intermediate bar 15 also of 2 inches depth and preferably about 4 /2 inches in width, i.e. substantially three times the width of one of the flanges 13, as shown in FIGS. 1 and 5, between the edges of the flanges 17 to which the expanded metal sections 18 are connected. Length of the unit may be as preferred for any particular requirement such as 8 or 10 feet. Through this arrangement, a plurality of the units 10 can be mounted in upright coplanar relation edge to edge and provide framing for a partition of a wall and conforming generally to a similar partition of a wall framed out with wooden 2" X 4"s. For doorways or other openings, suitable gaps can be provided between panel units, and with shorter panel units providing head closure framing above doorways and windows, and shorter panel portions also providing wall closure framing below the windows.

By way of example of use of the panel unit in a partition or wall, as represented in FIGS. 2 and 3, the length of the unit is such as to fit closely between a floor 24 and a roof or ceiling 25. Attachment of the panel to the floor is desirably effected through a horizontal base plate 27 which is preferably in the form of a channel or L-shaped cross-section sheet metal bar having a web flange secured in any suitable manner as by means of lag bolts, nails, or other fastening means to the floor and providing one or more upwardly extending longitudinally running flanges to which the lower end portions of the side bars 11 and the intermediate bar are secured by any suitable means such as spot welding, suitable clips, power driven fasteners, or the like. At the ceiling, the unit 10 is secured as by means of a sheet metal head runner strip 28 having a horizontal flat flange 29 secured in any suitable manner such as by nails, lag screws, and the like to the ceiling and with a downwardly projecting flange 30 to which the upper end portions of the panel unit bars are secured as by means of spot welding 31, power driven fasteners, or the like. If preferred, of course, the channel runner member 27 may be applied to the ceiling to secure the upper end of the panel unit and the I.- shaped member 28 may be secured to the floor. Through this arrangement, after the U-shaped runner member has been secured in place, the panel unit 10 can be inserted endwise therein and the unit then swung to position its other end within the member 28 against the flange 30.

After framing of a partition or a wall has been completed by securing the necessary number of the panel units 10 in place, suitable wall covering can be applied to one or both faces of the panel units. For example on an inside wall, wall-board panels 32 can be applied to the faces of the panel units 10 and secured thereto by means such as nails 33 driven directly into the side bar flanges 13 as shown in FIG. 3, and also secured by such nails 13 to the flanges 17 as indicated in FIG. 2, and also at the opposite face to the web flange 20 of the intermediate bar 15. Similarly, the wall covering panels 32 can be secured along with their upper and lower margins to the vertical flanges of the runner plates or strips 27 and 28, if desired. For sound-proofing, fire resistance and insulation, batts 34 (FIGS. 2 and 3) of suitable material such as fiberglass, rockwool, or the like, may be filled into the hollow spaces provided between the side bars 11 and the intermediate bar 15, and into the hollow space within the intermediate bar 15. At ei- ,ther or both faces of the batt 34 a vapor barrier sheet 35 may be provided.

Where the panel units 10 provide'outside wall framing, it will be readily apparent that instead of wallboard such as employed for inside wall and partition covering, exterior wall sheathing may be applied, and then any preferred outside wall covering applied thereover as preferred. Where the panel units 10 serve as direct load bearing wall framing, they can be erected on a base slab or floor and suitably propped similarly as with conventional framing, and either the member 28 or the member 27 applied as a cap plate on the upper end of one or more of the panel units, and a superstructure such as a floor or roof then erected on top of the thus provided framing, with the cap plates providing the means to which the super-structure is secured.

Instead of having the intermediate load carrying bar of a generally channel beam form as is true of the bar 15 shown in FIG. 1, a generally Z-shaped cross-section intermediate bar 37 (FIGS. 4 and 6) may be provided in a panel unit 10 which in other respects may be substantially the same as the panel unit 10. In this instance, the intermediate bar 27 has a web flange 38 extending between and maintaining a pair of oppositely projecting coextensive solid flat flanges 39 in spaced relation and at the opposite face planes of the unit 10. Ex-

panded metal sections 18' are integral with and extend diagonally from the distal edges of the flanges 39 to and are integral with the distal edges of the respective flanges 13 of the side bars 11' of the unit which lie in the other face plane of the unit 10 from that in which the respective flanges 39 lie. By preference, the web flange 38 is provided with an open mesh, expanded metal section 40. As shown, the solid bearing and nailing flanges 13' and 39 are all of substantially identical width. This Z-shaped formation of the intermediate bar 37 is, as will be apparent, a simpler formation than the intermediate bar 15, and for some purposes will be adequate from a load supporting consideration, and for some reasons may be preferred.

In addition to its use as in wall and partition structures, the panel unit 10 or 10 may be used as planking or deck covering such as in floors, roofs, walkways in bridge structures and overpasses, balconies, and the like. By reason of load supporting capabilities of the various bars in the units, they are capable of thoroughly withstanding not only compression but also tension loads applied there across from the faces of the unit. Hence, a roof or floor may be constructed by mounting the units 10, 10 in generally horizontal fashion on suitable supporting structure and then applying any suitable covering, i.e. roof covering, tread surface material, etc, to the upper face of the panels in the deck assembly. Where the structure is a roof, ceiling panels or sus pended ceiling may be applied to the undersurface of the erected panel units l0, 10'. On the other hand, the panel 10 or 10 if preferred, may be completely embedded as structural reinforcement within a concrete slab 41 (FIG. 5). In such an arrangement, the expanded metal body sections 18 and the expanded metal sections 23 of the intermediate bar 15 as well as expanded sections in the webs of the side bars 1] enable thorough interlocking of the panel section 10 within the concrete slab 41. This arrangement is especially suitable for use of light weight types of concrete, thereby gaining not only the advantages of the light weight reinforcement provided by the panel unit 10, but also the light weight characteristics of the concrete. Of course, if preferred, the panel unit 10 may be utilized to provide the internal body reinforcement for the concrete slab 41 and for some purposes may be preferred. One or both faces of the concrete slab 41 may be provided with a suitable sheathing or facing 42.

Efficient use may be made, as shown in FIG. 6, of the panel units of the present invention in prefabricated slabs such as may be filled with expanded polyurethane 43 or other light weight body material for which the panel unit may serve as the principal load sustaining structure. As shown the unit has been incorporated in the slab although the unit 10 may be similarly employed. In such a slab, the core material 43 fills the panel unit between the end bars 11 of the panel unit, and flush with the opposite face flanges l3 and 39. If preferred any suitable facing sheets 44 may be applied to either or both faces of the slab. Numerous and varied uses for such a slab will be readily envisioned, such as prefabricated wall or partition panels, roofpanels, floor panels, and the like. Where used as wall or partition panels, the prefabricated slab of FIG. 6 may be substituted for the drywall construction as described in connection with FIGS. 2 and 3.

It should be apparent that the present invention provides a versatile light weight high compression and tensile strength load bearing metal structural panel unit which is adapted to be made from light weight steel, aluminum, or other light sheet metal of suitable gauge to meet particular load requirements Maximum utility of material is provided for in the one piece thoroughly reinforced expanded metal body construction with the efficient load carrying flanged bar structures providing excellent compression load resistance not only longitudinally thereof but also transversely thereof, and in addition excellent tension load resistance transversely thereof. Manufacture of the panel units can be economically effected by utilizing coiled sheet metal stock slit according to expanded metal techniques in those areas to be expanded and shaped in those areas which provide the bars, utilizing metal expanding techniques and shaping rolls in continuous stream production. The finished metal panel units are provided with integral load bearing column or beam bars integrally connected in the preferred dimensional relationships for unit handling and erection such as in walls, partitions, roofs, floors, walkways, patios and the like.

It will be understood that variations and modifications may be effected without departing from the spirit and scope of the novel concepts of this invention.
