Abstract

An insulated concrete form system for constructing the exterior walls and gable ends of a structure is disclosed using expanded polystyrene forms that interconnect and are bonded to each other and to the structure's slab or foundation with concrete. Internal, substantially columnar voids are provided in each of the panel forms and both the interior and the exterior surfaces of the walls and gable ends may be finished with a variety of finish materials using furring strips that are incorporated into the interior and exterior surfaces of the forms.

Claims (5)

1. An insulated concrete form system for constructing the exterior walls and gable ends of a structure on an existing slab or foundation defining a perimeter of the structure and having a plurality of rebar segments disposed in and extending upwardly from the slab or foundation in predetermined, spaced apart relation to each other around the perimeter of the structure, said insulated concrete form panel system comprising: a plurality of substantially solid wall panels having an exterior wall surface and an interior wail surface disposed about the perimeter of the existing slab or foundation and extending upwardly therefrom to define said exterior walls of the structure, a plurality of corner panels having an exterior corner and an interior corner surface of one panel, one of said plurality of corner panels being disposed at each corner defining the perimeter of the structure and extending upwardly therefrom in interconnecting relation between an adjacent pair of said wall panels, and a plurality of gable panels having an exterior gable surface and an interior gable surface, at least one of said plurality of gable panels being disposed on each one of the opposed pair of said exterior walls and extending upwardly therefrom to define said gable ends of the structure, each said wall panel further comprising a tongue in a first lateral edge and corresponding groove in a second opposite lateral edge, each said wall panel, said gable panel and said corner panel further comprising a columnar void extending from a third lateral edge to a fourth lateral edge, a plurality of furring strips received in recesses spaced along said exterior and interior surfaces of said wall panel, said corner panel and said gable panel, and at least one screw member connecting a first furring strip on said respective exterior surface to a second furring strip on said respective interior surface, said screw passing through said void.

2. An insulated concrete form system as in claim 1 wherein each one of said plurality of wall panels is formed from EPS, each said void formed therein and extending from said third edge through said fourth edge such that each of said columnar wall voids is in registry with one of the rebar segments extending upwardly from the slab or foundation, each one of said panels further comprising a beam cavity formed along said third edge.

3. An insulated concrete form system as in claim 2 wherein each one of said plurality of corner panels is formed from EPS, said columnar corner void is in registry with one of the rebar segments extending upwardly from the slab or foundation, each one of said corner panels further comprising a corner beam cavity formed along said corner third edge, one of said corner side edges comprising a corner tongue and the other of said corner side edges comprising a corner groove whereby adjacent ones of said wall panels may be joined to said corner panel by inserting said tongue of one wall panel side edge into said corner groove and disposing said groove of said adjacent wall panel onto said corner tongue.

4. An insulated concrete form system as in claim 3 wherein each of said gable panels is formed from EPS, each of said columnar gable voids is in registry with one of said columnar wall voids, each of said gable further comprising a gable beam cavity formed along said gable third edge.

5. An insulated concrete panel form system as in claim 4 further comprising a plurality of wall and corner panel reinforcers each having a first end and a second end, said first end of each of said plurality of wall and corner panel reinforcers being attached to a corresponding one of the rebar segment extending from the slab or foundation, passing through its corresponding wall void or corner void, and said second end of each one said wall and corner panel reinforcers extending into its corresponding beam cavity, said system further comprising a plurality of gable reinforcers each having a lower end and an upper end, said lower end of each one of said gable reinforcers being attached to a corresponding second end of one of said wall reinforcers, passing through its corresponding gable void, and said upper end of each one of said gable reinforcers extending into its corresponding gable beam cavity; and said system further comprising horizontal reinforcers disposed within said corner beam cavity and said gable beam cavity whereby concrete may be placed in said wall voids, said corner voids, said gable voids, said beam cavities, said corner beam cavities, and said gable beam cavities to bond said exterior walls and said gable ends of the structure to each other and to the slab or foundation.
