A modular synthetic plastic concrete form structure for forming a concrete wall or free form or an enclosure having a curved corner. One form of the structure includes a pair of modular concrete impervious foamed forming panels each comprised of a series of modular foamed concrete forming sections stacked on top of one another and also disposed in end-to-end relation. The structure further includes a foamed curved corner form structure comprised of a series of arcuately curved corner sections stacked on top of one another providing a radially outer continuous curved corner area for forming a curved concrete corner. The sections each have means on upper and lower edges and at opposite vertical edges of interlocking the section in stacked end-to-end engagement with one another. The panels are positioned in spaced opposed relation. Ties connect the panels in transversely spaced relation and with the panels and the ties being permanently attached with the concrete poured between the panels as a reinforcing and heat insulator.

In a modular synthetic plastic concrete form structure for forming a concrete wall having a curved corner the improvement of the structure including a pair of modular concrete impervious foamed forming panels each comprised of a series of modular foamed concrete forming sections stacked on top on one another and also disposed in end-to-end relation, the structure further including a foamed curved corner form structure comprised of a series of arcuately curved corner sections stacked on top of one another providing a radially outer continuous curved corner area for forming a curved concrete corner, the sections each have means on upper and lower edges and at opposite vertical edges for interlocking the sections in stacked end-to-end engagement with one another, the panels being positioned in spaced opposed relation, and ties connecting the panels in transversely spaced relation and with the panels and the ties being permanently attached upon concrete being poured between the panels whereupon the panels serve as a heat insulator and the ties serve as reinforcing for the concrete and for securing the tees and panels in permanent assembly together certain of the forming sections being of a flat shape, the means at opposite ends of the curved corner sections and at the ends of the flat forming sections comprising complimentarily shaped tongues and grooves slidingly engageable in locked assembly together, the oppositve vertical edges of the flat and the curved sections having vertically extending matching hook-shaped tongue and grooves enabling the sections to be engaged in end-to-end interlocked assembly to prevent disassembly except by sliding the engaged tongues and grooves longitudinally of one another.
