ABSTRACT:
A tie for concrete forms includes an elongated strap with opposing first and second ends. The strap has an upwardly projecting intermediate portion which prevents the movement of form panels inwardly on the strap. A notch in each outer end of the strap receives a waler to hold the form panel from moving outwardly along the strap. Beveled ends allow the strap to be forced through a polystyrene panel without the need for forming an aperture in the panel to insertion of the tie. A removable end piece is also been designed for use with the tie. The end piece is a generally rectangular plate member with a slot in the middle and a pin projecting across the slot which will be received in the notch of the tie. In this fashion, the plate member is pressed against the form panel to prevent outward movement of the panel on the tie. The end piece may be removed as desired from the tie, thereby allowing reuse of the end piece in other locations.
