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.
Claims23
A forming system for building slab foundations including integral footing comprising:
- (a) a plurality of horizontally elongate generally vertical planar first panels forming an outer periphery of said building slab foundation and integral footing;
- (b) a plurality of horizontally elongate generally vertical planar second panels forming an inner face of said integral footing, said second panels having a lesser vertical dimension than said first panels;
- (c) connection means for coupling said first panels and said second panels, whereby no external bracing is required for lateral support of said first panels forming the outer periphery of said building slab foundation and integral footing.
A forming system for concrete slabs comprising:
- (a) an insulating panel of substantially rigid foam in linear form having a generally rectangular shape, said panel having an outer surface, an inner surface, a top edge, and a bottom edge;
- (b) a plurality of substantially rigid longitudinal rails affixed to said top edge and said bottom edge of said insulating panel;
- (c) staking means disposed interior of said inner surface of said insulating panel for securing said insulating panel to a body of earth;
- (d) bracing means disposed interior of said inner surface of said insulating panel for securing said insulating panel to the earth, therein providing lateral support for said insulating panel;
- (e) connection means for coupling a plurality of said insulating panels in a generally end-to-end fashion, thereby forming a substantially rigid unitary longitudinal form member to retain concrete poured into a slab floor configuration becoming an integral part of the periphery thereof.
