A form tie for interlocking parallel and spaced foam panels. The tie is formed of an elongate planar strap having a lattice arrangement of openings for flow of concrete. Each of the opposite ends of the strap have an end plate and an inside plate spaced to bracket a corner of a foam form panel with each of the plates extending in a perpendicular or "Y" axis direction to the longitudinal or "X" axis of the strap. Each of the end portions forming the bracket also has vane shelves extending between the end and inside plates in a "Z" axis direction to the strap for support of the foam form panel corner. "U" shaped holders in the edges of the strap and overcenter tabs in the openings provide retainers to hold reinforcement bars, commonly termed rebar. The strap is preferably formed of a heavy gauge polypropylene. |
