ABSTRACT:
Disclosed herein is a concrete form assembly for pre-casting concrete walls which includes a three-piece base plate, side rails and headers which interfit between the side rails and can be adjusted to any spacing for different length and width concrete wall panels. A quick release clamp has a pin which interfits with registrable apertures in the form parts for fastening the base plate, side rails and headers in unitary assembly during the pouring process. A cam surface on one of the clamp jaws urges the form parts together when the clamp is swung into clamping position. Out-turned flanges on the side rails and projecting portions on the headers provide clamping surfaces.
