Abstract: A modular structure for constructing building walls for domestic and commercial housing including inner and outer panels interlocked at the edges by dovetail grooves and retained in spaced relation by wire grills engaged with the edges of the panels. An insulation block is provided, to span a single panel or multiple panels, and positioned against the inside surface of an inner or outer panel. This block is located by individual rods of the wire grills and retained in position by said rods. Multiple blocks, face to face, can be utilized to increase the insulation factor as desired.

Abstract: Interfitting structural modules are built up in overlapping courses or tiers on a horizontal foundation into the desired building wall formation and either used as such or as a form assembly into which concrete may be poured. Each module includes a pair of laterally spaced elongated parallel vertical panels interconnected at their tops and ends by wire grating spacers. Corner constructions are provided which may be utilized for right angle corners or corners with obtuse angles, there being a suitable joint provided for the intersecting inside and outside panels together with special corner wire grids for stabilizing the related parts of the corner constructions.
