Pre-cast insulated wall structure

Claim 1

A panel for use as a building unit and including large, planar, spaced side faces interconnected by parallel end edges and parallel side edges, said panel comprising a continuous core of reinforced, monolithic cementitious material having side faces spaced inwardly from the side faces of the panel, a plurality of stud members partially embedded in each side surface of the cementitious core, said stud members being parallel to each other, laterally spaced from each other, extending from side edge to side edge of the panel, having the outer surface thereof substantially flush with the side faces of the panel, and having a major portion of their thickness projecting from the core, means on each stud member embedded in the core to lock the stud members thereto, insulation panels disposed against each side face of the panel and between adjacent stud members, said insulation panels completely filling the space between adjacent stud members with the outer side faces thereof substantially flush with the side faces of the panel and the outer surfaces of the stud members, said stud members and insulation panels being assembled with core when the cementitious material is fluent for securing the stud members to the core with the insulation panels slowing moisture flow from the cementitious material while it hardens thereby controlling the curing time and strength of the core, said stud members being consturcted of material penetrable by fasteners to facilitate attachment of a finish panel to the planar side faces of the panel.
