Abstract: A two story building consistng of three elongated box-shaped prefabricated sections wherein there are two sections connected together side by side on the ground floor and a further section is stacked on one of the ground floor sections to comprise the second floor. Each section includes a framework of metal beams and the walls of the section are defined at least in part by the metal beams of the framework. The walls may include openings for doors, windows and interior passageways. Each wall is composed of cast concrete and has embedded therein a plurality of stiffening bars. The stiffening bars are inclined to both the horizontal and vertical and have bent-over ends which are disposed at corners of the walls without touching the proximate metal framework. The stiffening bars also have portions near each corner of an opening and, between openings and vertical framework components, the stiffening bars cross each other to produce a truss-like structure embedded in the concrete of the walls.

Abstract: A building panel constituting a prefabricated module for attachment to adjacent studs of a building wall. When used in substitution for conventional stucco construction, the metal frame of the panel is filled with cement stucco. Tabs on the sides of each panel include inwardly projecting legs nailable to the sides of the adjacent studs for concealed attachment. The legs are all laterally offset from the panel sides in the same direction, for nailing from the same direction, and they are also longitudinally or vertically offset so that like panels can be successively butted together at their side edges without interference between the legs of the respective tabs. The panel can also be provided with connection brackets for attachment to the top or bottom plates of a building wall. In normal use the panels are vertically oriented, but they are adapted for transverse mounting to the building wall studs and headers in certain situations.
