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.

  • Patent number: 4194717
    Abstract: A concrete wall form structure of the type having a pair of aligned contiguous pre-fabricated panel units disposed in an edged-edged, upstanding relationship. Each panel unit has one of its marginal frame members abutting an adjacent marginal frame member of the panel unit. The panel unit edges have a plurality of aligned apertures in each of the abutting frame members whereby at least two apertures of abutting frame members are aligned and receive an elongated bolt. One of the panel units slidably carries the bolt so that it is movable between a retracted rear position wherein the bolt is moved within the confines of that one panel unit and an advanced forward position wherein the forward end of the bolt is projected through both apertures of the adjacent frame members and within the confines of the other panel unit.
