Abstract
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.
