Abstract
Abstract A light weight load bearing metal structural panel is provided which is adapted to replace other forms of wall and partition studding or framing and to which suitable wall coverings are adapted to be secured such as wall board or other desirable sheathing materials, and the like. 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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
321 words
A light weight high strength compression and tension load sustaining structural panel unit formed from sheet metal and especially suitable to be fabricated in 4 feet width by 8 to 10 feet length and 2 inches thickness, comprising: spaced coextensive generally U-shaped load supporting side channel bars provided with web portions defining side edges of the panel unit and each bar having two solid marginal flanges extending inwardly of the unit and lying in respective parallel opposite face planes of the unit and providing bearing and nailing surfaces of substantial and about equal width; a single intermediate load carrying bar of rugged channel beam multi-flange cross section coextensive with and substantially spaced from and midway between said side bars and being of no greater than about three times the width of said side bar marginal flanges; said intermediate bar having: a pair of spaced apart oppositely extending coplanar solid bearing and nailing surface flanges, the distances between the remote edges of said pair of flanges being about three times the width of one of said marginal flanges, and said pair of flanges lying in one of said face planes of the unit and coplanar with the marginal flanges in said one face plane; a solid bearing and nailing surface web flange at least as wide as one of said marginal flanges lying in the other of said face planes and coplanar with the marginal flanges in said other face plane; and respective angularly extending side wall flanges rigidly connecting and spacing the adjacent edges of said web flange and the proximal edges of the pair of flanges; and open mesh body portions of the unit connecting the marginal flanges of said side bars in said one face plane with the respective distal edges of the adjacent ones of said pair of flanges of said intermediate bar and thereby maintaining the side bars and the intermediate bar in substantially fixed spaced relation.
Claim 2
Dependent Claim
321 words
A light weight high strength compression and tension load sustaining structural panel unit formed from sheet metal and especially suitable to be fabricated in 4 feet width by 8 to 10 feet length and 2 inches thickness, comprising: spaced coextensive generally U-shaped load supporting side channel bars provided with web portions defining side edges of the panel unit and each bar having two solid marginal flanges extending inwardly of the unit and lying in respective parallel opposite face planes of the unit and providing bearing and nailing surfaces of substantial and about equal width; a single intermediate load carrying bar of rugged channel beam multi-flange cross section coextensive with and substantially spaced from and midway between said side bars and being of no greater than about three times the width of said side bar marginal flanges; said intermediate bar having: a pair of spaced apart oppositely extending coplanar solid bearing and nailing surface flanges, the distances between the remote edges of said pair of flanges being about three times the width of one of said marginal flanges, and said pair of flanges lying in one of said face planes of the unit and coplanar with the marginal flanges in said one face plane; a solid bearing and nailing surface web flange at least as wide as one of said marginal flanges lying in the other of said face planes and coplanar with the marginal flanges in said other face plane; and respective angularly extending side wall flanges rigidly connecting and spacing the adjacent edges of said web flange and the proximal edges of the pair of flanges; and open mesh body portions of the unit connecting the marginal flanges of said side bars in said one face plane with the respective distal edges of the adjacent ones of said pair of flanges of said intermediate bar and thereby maintaining the side bars and the intermediate bar in substantially fixed spaced relation.
