ABSTRACT:
A concrete forming system for the casting of floating slab building foundations with perimeter insulation. Form panels (14A), (14B), (14C), and (14D) comprised of foam core (54) and metal rails (42) and (44), and overlain with stress skins (50), are connected by form tie assemblies (18A), (18B), (18C), and (18D). A protective shield (40) covers the exposed portions of panels (14A) and (14D). Metal stakes (16) anchor formwork assemblies to the earth. System includes embedded anchors (64) and (38). Panel connectors (30) and (32) allow formwork assemblies to be pre-assembled into long lengths, which provides straight and level slab edges and great labor savings. Forming system provides lightweight forming panels, stakes, and lateral bracing which remain in place, providing perimeter insulation and finish exterior surfaces.
