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.
