A concrete wallform system comprises a vertical waler (formed of a pair of spaced channel beams bolted back to back) for stiffening the horizontal joists, which in turn back the forming panels, and a tie rod extending between the channel beams, and a tie connector plate connecting the tie rod to the waler. The connector plate is formed as a flat plate with an aperture approximately at the center and a hook portion along one edge thereof. The hook portion overfits a lip on one wall of one of the channel beams. A bolt clip near the other edge of the flat plate fastens the connector plate to a lip of a corresponding wall of the companion channel beam. This bolt clip is standard hardware of the type used on aluminum joists (e.g., to join the waler to the joists). A wing nut disposed at the aperture stresses the tie rod so that when wet cement is poured into the wallform, forces that are transmitted through the wallform to the waler are taken up by the tie rod. Preferably, a raised spacer portion is provided on the back surface of the connector plate to aid in maintaining the spacing between the channel beams of the waler and for locking the hook portion on its respective channel flange.
A connector plate adapted to be mounted on the outer flanges of a pair of U-shaped channels joined in back-to-back spaced relation as a concrete forming waler, comprising a plate portion of a size adapted to overlie both said outer flanges from beyond the outside edge of one said flange to beyond the outside edge of said other outer flange, hook means at one edge of said plate adapted for securing said plate to the outer edge of one of said flanges, fastening means adapted for use in securing said plate to said other flange, a raised spacer portion formed in the bottom face of said plate and dimensioned to fit snugly in the gap between said channels when said plate is hooked in place on said waler, and a tie rod aperture through said plate substantially centered through said raised portion.
A connector plate adapted to be mounted on the outer flanges of a pair of parallel beams fixed in spaced relation as a concrete forming waler, comprising an extruded aluminum plate portion of a size adapted to overlie both said outer flanges from beyond the outside edge of one said flange to beyond the outside edge of said other outer flange, hook means at one edge of said plate portion adapted for securing said plate to the outer edge of one of said flanges, raised spacer means formed in the bottom face of said plate and dimensioned to fit snugly in the gap between said channels when said plate is hooked in place on said waler, fastening means adapted for use in securing said plate to said other flange, and a tie rod aperture through said plate adapted to be substantially centered in the spacing between said beams said hook means having an inwardly directed hook lip dimensioned to bear against the inner surface of one of said flanges, and said plate portion having a clearance trough formed therein where the latter joins said hook means.
