Abstract
A synthetic plastic concrete wall tie comprising a pair of triangular truss sections disposed in end-to-end relation, an intermediate web section joining the truss sections of the apexes of triangles of the triangular truss sections, and T-shaped end sections at opposite ends of the tie with each end section being formed integral with its stem joined with the associated triangular truss section, the cross piece of each T-shaped end section comprising means for anchoring the tie to a slotted wall section when assembled therewith. The tie is usable with modular foamed plastic concrete form structure having a pair of modular concrete forming panels. The panels are comprised of a series of modular concrete forming sections stacked on top on one another in secured assembly and also disposed in end-to-end relation. The panels are positioned in spaced opposed relation with vertically spaced rows of T-shaped tie slots in the opposed sections positioned in longitudinally spaced transversely aligned relation along the upper and lower edges and which slots are hidden from view when viewing outer surfaces of the stacked sections. The ties hold the sections in assembly when secured in the tie s…
