Abstract

Abstract Construction forms for the erection of structural assemblies utilizing a variety of extruded or cast individualized building forms in a combined array to define a single structure composed of standard forms having a plurality of cells with the ends thereof biased to include 45° male-female miter elements. Also included are accessary forms having at least one biased termination end which includes male-female miter being disposed to impart dual direction to the extruded form. Within the said forms there are structural supports for reinforcing the forms while at the same time allowing the forms to carry utility conduits and supports for cables, insulation, air, water, gas, etc.
