Abstract

A modular synthetic plastic concrete form structure which comprises a pair of modular concrete impervious forming panels each comprised of a series of modular concrete forming sections stacked on top on one another and also disposed in end-to-end relation. The sections each having means on its upper and lower edges and its opposite vertical edges for interlocking the sections in engagement with one another. The panels each being comprised of a synthetic plastic and the panels are positioned in spaced opposed relation. Tie slots are provided in the opposed sections positioned in longitudinally spaced relation along the upper and lower edges. Synthetic plastic ties are provided with each having opposite enlarged tie ends retainingly engaged in the tie slots securing the sections in opposed spaced relation. Modular transversely extending closure panels are mounted between the opposed panels providing end closures for confining poured concrete within the form defined by the opposed panels and the end closure panels. Modular attachment means are provided between opposed faces of the opposed panels and opposite ends of the closure panels to secure the assemblage in unitary relation to de…
