ABSTRACT:
A gang form or tie rod holding bolt is adapted for holding a tie rod passing through abutting frames of prefabricated panel units, the frames having mating slots. The tie rod holding bolt includes a body portion and a slot leg for extending through the mating slots, a middle leg for loading the frames, and a tie rod engaging leg for transferring a load from the tie rod to the holding bolt. The form slot leg and the middle leg are horizontally offset to straddle the tie rod and the middle leg is adapted to transfer the load to the frames, thereby providing the bolt with great stability under heavy loads. The design avoids eccentric load on the bolt. An assembly includes the bolt, tie rod, wedge pin and two frames.
