ABSTRACT:
A method and associated form assembly for forming pre-cast structural panels includes the steps of and associated apparatus for constructing an open-top disassemblable form box, reinforcing the form box with a collar assembly affixed around the form box for rigidly maintaining the shape thereof, with divider assemblies in the form box to provide a plurality of form compartments adapted to form structural panels disposed on-edge on the form box bottom panels and with insulation panels supported in the form compartments, pouring a hard-setting material into the form compartments, allowing the material to harden into structural panels, and at least partially disassembling the form box to expose a panel for removal. As preferably embodied, end wall separator panels support both the insulation panels in desired positions within the form compartments as well as the divider assemblies, and are releasably attached to and supported by an end wall assembly frame, with bottom separator panels at the bottom of the form box in correspondence with the end separator panels. A method of wall construction further includes the steps of placing a steel cable around the edges of all the concrete layers of the hardened panel, standing the panel up-right, lifting the panel to the desired position on the structure under construction, positioning the panel between reinforcing rods embedded in the structure, removing the cable, and filling the inter-panel spacings, with reinforcing rod encased therein, with mortar.
