Abstract
A concrete form assembly comprises spaced apart form members that are retained in position during concrete pouring by an arrangement that includes spacer elements, plastic tie rods, and anchors. The anchors are on the outsides of the forms and grip the tie rods. Each anchor comprises a tapered jaw cluster in a tapered shell so arranged that outward forces applied to the forms due to concrete being poured therebetween increases the grip of the anchors on the tie rods to retain the forms at the established spacing.
