Abstract
In order to provide self-containment in a waler clamp assembly with adjustment capabilities, the assembly includes a generally U-shaped bracket having a pair of generally parallel spaced legs joined at one end by a connecting bight portion with one of the legs having a distal end with a latching key adapted to fit into a hole in a form support. Specifically, the latching key is adapted to fit into the hole in a first orientation of the bracket relative to a concrete form and is also adapted to be securely locked within the form support in a second orientation of the bracket relative to the concrete form, and the bracket also has generally aligned openings in the legs near and generally parallel to the bight portion at a point opposite the latching key. With this arrangement, the tapered wedge projects through the generally aligned openings in the bracket, is movable generally perpendicular to the legs of the bracket to be driven in wedge fashion to force a waler board carried by the bracket against the concrete form, and is retained in integrally associated relation with the bracket.
