Abstract

Abstract Wall structure modules comprising a plurality of narrow, substantially ceiling high panels of integral sandwich construction with a thickness of insulation molded between two thicknesses of light weight concrete. There are tongue and groove configurations along opposite sides of the panels conditioning them to be nested together. A full-height steel stud is encased in each exterior panel and has a small bracket at the top exposed for attachment of a top plate, which fits over the panels of a complete wall section to unitize it. Interior panels are similar but the steel studs are full height in every other panel only. A transverse channel extends across the bottom of each panel on the inside, the lower flange of which is secured to the sub-floor. In the assembled wall these channels are aligned to serve as a conduit for plumbing and electrical wiring.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 126 words
Wall structure modules comprising: a plurality of narrow, substantially ceiling high panels of lightweight concrete; tongue and groove configurations along opposite sides of said panels conditioning them to be nested together in juxtaposition; a full height load bearing steel "c" stud embedded in certain of said panels; a cap channel adapted to fit over and along the tops of a plurality of nested panels; means for securing said cap members to the load bearing studs in said nested panels; means forming a horizontal raceway for piping and electrical conduits across the lower ends of said panels; an electric outlet box in at least one of said panels opening to the interior surface thereof; and a duct depending from said outlet box and opening into said raceway.
Claim 2
Dependent Claim 126 words
