ABSTRACT:
A tie bracket for supporting opposing synthetic foam insulating panels of a concrete receiving form, and a form utilizing such brackets. The tie bracket has intersecting horizontal and vertical members forming circumferentially closed openings therein. Most openings are arranged in horizontal series. An upwardly open trough is formed in each tie bracket. The horizontal members span and connect spaced apart parallel plates. The plates of each tie bracket are embedded in one foam insulating panel and are of height equal to that of the insulating panel. Each insulating panel has projections formed in its upper surface and cooperatively formed notches formed in its lower surface to enable interlocking and alignment of vertically stacked forms.
