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. The projecting forward end of the bolt is provided with an elongated slot which receives a tapered wedge that bindingly engages the adjacent frame member to lockingly secure the panel units to each other.
