Abstract
Abstract An improved clamp for use in joining reinforcing beams and concrete forms having tie rods therethrough. The clamp includes a generally channel-shaped body having a web portion and a pair of depending sidewalls. A front plate extends transversely between the front ends of the sidewalls and extends upwardly above the web portion for holding the reinforcing beam against the concrete form. The front plate is provided with an opening therethrough adjacent to and below the web portion for receiving the end of a tie rod, and a pair of retainer flanges on the front plate slidably receive a slide plate. The slide plate includes an inclined, raised central portion which is provided with a longitudinally extending slot terminating in an opening for receiving the end of a tie rod.
