ABSTRACT:
A spreader bar assembly which is designed for use in a concrete wall form and cooperates with a she-bolt on one end of a tie rod in preventing inward collapse of the adjacent side of the form prior to pouring of wet concrete between the opposed form sides. A washer which is loosely and telescopically received over the she-bolt bears against the outer side of the adjacent form side and is clamped thereto by a nut, while a pivoted spreader bar proper which is captured on the washer is capable of swinging movement in a vertical plane between a locking position wherein it passes across the front or outer face of the nut and assimilates any tendency for inward collapse of the adjacent form side, and an out-of-the-way position wherein it exposes the nut for manipulating purposes.
