ABSTRACT:
The apparatus is an assembly jig for constructing prefabricated concrete wall sections. Two parallel elongated "L" cross section members, each with an outer vertical wall, are connected to a base structure with pivots, and several separated sections of inner vertical walls are attached by pivots at the edge of the base of each "L" to form parallel channel molds with spaces in the inner walls to receive prefabricated concrete studs. The wall is constructed by placing concrete studs and insulation sheets between the channels, and pouring concrete into the channel molds and over the studs and insulation sheets. The "L" members are pivoted down to release the hardened concrete beam which has been formed within each mold and thereby facilitate removal of the finished wall section from the assembly jig.
