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.

Abstract: A column mold system has at least two mold walls for forming a column mold section where the walls are held together by corner brackets. The corner brackets are right angle iron members with a pair of integral legs bent at their upper ends for forming a lifting end. Each leg of the corner bracket has slots correspondingg to slots in the other leg. The slots match similar slots on the ends of the mold walls for joining the corner bracket to the mold wall using wedge connectors. The lifting end of the corner brackets are used to stack mold sections one on top of the other and to strip the mold sections from a poured concrete column.

Abstract: A gang tie holding bolt holding tie rods of multiple panel units in gang form sections for pouring concrete has a folded over body portion with two spaced parallel flanges from one of which a finger is formed to extend through adjacent frame members of adjacent panel units, the other flange being cut away opposite the finger. Spaced from this finger is a hole through both flanges to receive a key. The tie rod passed between the flanges and the loop in the end of the tie rod receives the key to hold the bolt and tie rod in position. The shoulders formed on the two flanges by the cut away portions thereof engage the outer faces of adjacent frame members to prevent tipping of the bolt thus locking the panel units more securely together.
