ABSTRACT:
A three-layer insulated concrete panel includes as the middle layer an insulating slab having grooves which provide a form for casting of concrete supporting ribs integral with a layer of concrete cast over the grooved face. A layer of material, such as particle board, is bonded to the ungrooved face of the slab. In preparing the panel, the slab is placed on a flat surface with the particle board face down. Forms are then placed in spaced-apart relation to panel edges, and concrete is cast into the forms and grooves and over the grooved panel face. The insulating slab provides a form for casting of supporting ribs and is permanently retained in the panel, giving it a high insulating value. An assembly of such panels in a roof or ceiling structure is disclosed wherein individual panels are placed in final position, and joints between adjacent panel edges are obtained by covering exposed strips along adjacent panel edges with a cap member and applying concrete over the cap member.
