124366 ABSTRACT OF THE DISCLOSURE 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.
