ABSTRACT:
A wedge and bolt assembly serves to temporarily connect two prefabricated panel units for use in assembling a concrete wall form. A bolt support member is mountable on a prefabricated panel, and includes a first hollow passage formed therethrough to slidingly receive a bolt. The bolt has a main body portion with two recesses formed therein to receive an engaging member. The bolt also has a projecting end with a transverse slot formed therethrough for receiving a wedge after insertion through extending flanges of aligned panel units. The bolt support member includes a second hollow passage formed therein transverse to the first hollow passage in which an engaging member is disposed, the engaging member being biased into the recesses of the bolt by a coil spring or the like. A set screw or the like is inserted in the second passageway of the bolt support member to retain the spring and engaging member therewithin.
