Abstract
A composite concrete wall form unit or assembly consisting of three metal-clad panels connected together in edge-to-edge relationship, the medial panel embodying a plywood facing with a rectangular metal-reinforcing or backing frame, such medial panel constituting a prefabricated fill-in panel for making up an odd dimension which exists between two adjacent outer panels. Such outer panels are of a larger size and likewise are prefabricated in such a manner that they possess a common plywood facing which extends across the plywood facing of the smaller medial panel in face-to-face relationship and thus bridges the odd dimension. A special and novel transition bolt is used for connecting each side rail of the reinforcing frame of the medial panel to the adjacent side rail of the adjacent outer panel.
