Abstract
Abstract A vertically elongated module of sheet metal has a center panel with side flanges turned inwardly along each edge, and with narrow return flanges on the free edges of the side flanges. The upper and lower ends of the return flanges have tabs turned outwardly to the center panel, and the upper and lower ends of the side flanges are turned laterally as end flanges in lapped relation to the tabs. Turning of the end flanges leaves transverse flat nailing strips along the upper and lower ends of the module. The side flanges are of less width than the width of a standard 2×4. When erected into a wall, successive modules are secured in side-by-side relation on the wide side of a 2×4 plate by nailing their lower nailing strips along the narrow side of the lower plate, and an upper 2×4 plate is similarly secured to the upper nailing strips. Furring strips are secured along the inner sides of each pair of adjacent return flanges, with the ends of the strips abutting the plates, and with the inner sides of the furring strips flush with the inner edges of the plates. Inner panels are secured across several furring strips with the ends of the panels lapped on the inner sides of the plates. The inner panels have holes near their tops for introduction of insulating material.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
186 words
A vertically elongated load bearing wall module of thin sheet metal and comprising as integral parts: a vertically elongated center panel having an upper edge, a lower edge, and vertically elongated opposite side edges, and substantially parallel vertically elongated side flanges extending in the same direction from said opposite side edges of said panel; vertically elongated return flanges extending toward each other from the free side edges of said side flanges and end flanges extending toward each other from the upper and lower ends of said side flanges, said return flanges and end flanges and center panel together completing the peripheral wall of each of a pair of boxes which open toward each other across the width of said center panel, said side flanges respectively forming the bottoms of said boxes; and tabs extending inwardly from the ends of said return flanges toward said center panel in lapped relation with said end flanges; said center panel having nailing strips coplanar therewith and projecting vertically beyond said end flanges at each end of the panel, said return flanges being spaced behind the plane of said nailing strips.
Claim 2
Dependent Claim
186 words
A vertically elongated load bearing wall module of thin sheet metal and comprising as integral parts: a vertically elongated center panel having an upper edge, a lower edge, and vertically elongated opposite side edges, and substantially parallel vertically elongated side flanges extending in the same direction from said opposite side edges of said panel; vertically elongated return flanges extending toward each other from the free side edges of said side flanges and end flanges extending toward each other from the upper and lower ends of said side flanges, said return flanges and end flanges and center panel together completing the peripheral wall of each of a pair of boxes which open toward each other across the width of said center panel, said side flanges respectively forming the bottoms of said boxes; and tabs extending inwardly from the ends of said return flanges toward said center panel in lapped relation with said end flanges; said center panel having nailing strips coplanar therewith and projecting vertically beyond said end flanges at each end of the panel, said return flanges being spaced behind the plane of said nailing strips.
Claim 3
Dependent Claim
131 words
A wall module as defined in claim 1, in which said module is formed of a sheet of vertically elongated substantially rectangular shape and having two pair of parallel substantially vertical slits in the upper edge thereof substantially vertically aligned with two pair of parallel substantially vertical slits in the lower edge thereof, each of said four pair of slits being disposed close to a corresponding one of the four corners of said sheet, two pair of substantially vertical fold lines respectively terminated by the blind ends of the two pair of slits in the upper sheet edge and the two pair of slits in the lower sheet edge, said fold lines contacting said return flanges, side flanges and center panel, said slits separating said tabs, end flanges, and nailing strips.
Claim 4
Dependent Claim
26 words
A wall module as defined in claim 1 in which the width of said side flanges is materially less than the width of a standard 2×4.
Claim 5
Dependent Claim
38 words
A wall module as defined in claim 1 in which the width of said nailing strip on one end of said module as measured from the adjacent end flanges is greater than the thickness of a standard 2×4.
Claim 6
Dependent Claim
57 words
A wall module as defined in claim 1 in which the thickness of said sheet metal is of the order of 1/64 of an inch; and the widths of said side flanges and said end flanges measured perpendicularly from said center panel are of the order of one inch less than the width of a standard 2×4.
Claim 7
Dependent Claim
189 words
A modular wall comprising: a plurality of like, vertically elongated and thin sheet metal wall modules arranged side by side, each module having a planar central panel with integral and parallel side flanges along its lengthwise edges, return flanges on the free edges of said side flanges and end flanges extending toward each other from the ends of said side flanges; a lower plate member arranged transversely of said wall modules and in supporting contact with the end flanges at the bottoms thereof; a top plate member arranged in supported contact with the end flanges at the tops of said wall modules; upper and lower plate members; integral nailing strips projecting vertically from said panels beyond said side flanges and secured in lapped relation to the edges of plate members; and furring strips secured in lapped relation to the outer sides of adjacent pairs of said return flanges and extending in abutting relation to and between the opposed sides of said plate members; and facing panels secured in planar relation to each other and in lapped relation to the adjacent sides of said plate members and said furring strips.
Claim 8
Dependent Claim
189 words
A modular wall comprising: a plurality of like, vertically elongated and thin sheet metal wall modules arranged side by side, each module having a planar central panel with integral and parallel side flanges along its lengthwise edges, return flanges on the free edges of said side flanges and end flanges extending toward each other from the ends of said side flanges; a lower plate member arranged transversely of said wall modules and in supporting contact with the end flanges at the bottoms thereof; a top plate member arranged in supported contact with the end flanges at the tops of said wall modules; upper and lower plate members; integral nailing strips projecting vertically from said panels beyond said side flanges and secured in lapped relation to the edges of plate members; and furring strips secured in lapped relation to the outer sides of adjacent pairs of said return flanges and extending in abutting relation to and between the opposed sides of said plate members; and facing panels secured in planar relation to each other and in lapped relation to the adjacent sides of said plate members and said furring strips.
Claim 9
Dependent Claim
34 words
A modular wall as defined in claim 6, in which each facing panel engages at least four of said furring strips; and there is caulking material between adjacent side flanges of said wall modules.
Claim 10
Dependent Claim
30 words
A modular wall as defined in claim 6 in which the nailing strip at the bottom of each wall module projects below the lower side of the lower plate member.
Claim 11
Dependent Claim
27 words
A modular wall as defined in claim 6 which includes insulation material disposed between the central panels and said facing panels and extending between said plate members.
