Abstract
Abstract A sheet metal face for a structural panel has at least one edge portion bent and folded to define a recessed double-thickness flange. A plurality of longitudinally-spaced slots in the flange are used for attaching mounting members having upwardly facing hooking projections receivable in a hook pocket integral with a wall-hanging structural unit. A non-metallic protector strip may be interposed between the hooking projections and hook pocket. The structural unit has bottom and rear sheet metal panels with an integral assembly flange and assembly hook. A load bar assembly may be interposed between the mounting members and the structural unit.

Claim 3
Dependent Claim
34 words
The sheet metal face of claim 1 wherein each of said main folded portions includes a terminal folded portion extending outward from said main folded portions in a direction opposite to said terminal flange.
Claim 4
Dependent Claim
53 words
The sheet metal face of claim 2 wherein said terminal folded portions are inclined to extend outwardly and back toward said web, said terminal folded portions having terminal folded portion ends spaced from said web portion to define mounting spaces, said openings in said main folded portions being aligned with said mounting spaces.
Claim 5
Dependent Claim
40 words
The sheet metal face of claim 3 wherein said web portion of terminal flanges are substantially in alignment with one another and extend substantially perpendicular to said central portion, said main folded portion being substantially parallel to said central portion.
Claim 6
Dependent Claim
83 words
The sheet metal face of claim 3 wherein a pair of said faces are reversely positioned with said central portions thereof in substantially parallel spaced-apart relationship with said terminal flanges thereon overlapping one another, and securing means for securing said overlapping terminal flanges together to define a substantially rectangular panel having panel edge portions of substantially channel-shaped cross-sectional configuration including outwardly opening channel spaces defined by spaced-apart legs formed by said main folded portions and a base formed by said overlapping terminal flanges.
Claim 7
Dependent Claim
32 words
The panel of claim 5 wherein each of said main folded portions includes a terminal folded portion extending outward from said main folded portions in a direction opposite to said terminal flange.
Claim 8
Dependent Claim
51 words
The panel of claim 6 wherein said terminal folded portions are inclined to extend outwardly and back toward said web, said terminal folded portions having terminal folded portion ends spaced from said web portions to define mounting spaces, said openings in said main folded portions being aligned with said mounting spaces.
Claim 9
Dependent Claim
38 words
The panel of claim 7 wherein said web portion of terminal flanges are substantially in alignment with one another and extend substantially perpendicular to said central portion, said main folded portion being substantially parallel to said central portion.
Claim 10
Dependent Claim
74 words
The panel of claim 5 wherein a pair of said panels are positioned substantially vertically in substantially aligned relationship with panel edge portions thereof in spaced-apart relationship to define a pair of panel mounting edge portions, a post member positioned between said pair of panel mounting edge portions, and said post member extending at least partially into said channel spaces between said legs to form a wall assembly from said post and said panels.
Claim 11
Dependent Claim
44 words
The wall assembly of claim 9 and further including elastomeric gasket members positioned between said post and said panel mounting edge portions, said gasket members having terminal gasket flanges extending over said main folded portions for concealing said openings in said main folded portions.
Claim 12
Dependent Claim
83 words
The wall assembly of claim 10 wherein each of said main folded portions includes a terminal folded portion extending outward from said main folded portions in a direction opposite to said terminal flanges, said terminal folded portions having terminal folded portion ends spaced from said web portions to define mounting spaces, said openings in said main folded portions being aligned with said mounting spaces, and said gasket flanges extending over said terminal folded portion ends across said mounting spaces toward said web portions.
Claim 13
Dependent Claim
25 words
The wall assembly of claim 11 wherein said terminal folded portions are inclined to extend back toward said web portions from said main folded portions.
Claim 14
Dependent Claim
100 words
A wall assembly comprising; a pair of substantially vertical panels having mounting panel edges facing one another in spaced-apart relationship, said mounting panel edges having channel-shaped cross-sectional configurations including outwardly opening channel spaces defined between spaced-apart channel legs and a channel base, a post positioned between said mounting panel edges, said post extending at least partially into said channel spaces between said channel legs, a plurality of longitudinally-spaced mounting openings in said channel legs, elastomeric gaskets positioned between said post and said mounting panel edges, said gasket having gasket flanges extending over said channel legs and substantially covering said openings.
