ABSTRACT:
An insulated concrete building panel having an internal slab of insulating material, layers of concrete on each of the slab faces, and a concrete frame around its edges. One face of the slab has a pattern of grooves into which concrete is cast to provide ribs that are cast integral with the outer layer on that face. The other face has ridges, preferably of trapezoidal cross section that, when placed upon a bottom layer of cast but uncured concrete, become intermeshed with the bottom layer. The panels are prepared by first casting a layer of concrete on a horizontal surface, placing the slab, grooved face up, on the cast but uncured layer, and casting concrete over the grooved face, into the grooves and around the slab edges. Panels having this structure are useful for constructing buildings such as warehouses where long panel lengths of concrete inner face and internal insulation are needed.
