Abstract: A freestanding structural wall panel comprising a plurality of elongated spaced apart wire assemblies comprising first and second elongated wire members each formed into a continuous generally triangular shape, a first longitudinal wire member coupled to the lower apices of the first and second triangular wire members such that the apices of one triangular wire member are staggered with respect to the apices of the other triangular member and the planes of the first and second continuous triangular members form an angle with each other and second and third longitudinal wire members coupled to the upper apices of the first and second triangular wire members respectively, a layer of concrete partially embedding the wire members, and a layer of polyurethane foam formed for insulation purposes on the concrete layer and partially embedding the wire members whereby ducts, pipes and wiring may be placed under the non-embedded portion of the wire members and wall board may be attached to the wire members.

Abstract: The present invention is directed to improvements in the art of producing monolithic concrete structures, and especially modular building components generally in the form of inverted U-shaped members of cast concrete. The invention is further directed to an improved apparatus, and more specifically an improved casting form assembly for the practice of the method hereinabove set forth.
