Abstract

Abstract An insulated concrete form wall building system wherein a first embodiment includes a pair of spaced apart elongated expanded polystyrene sidewalls, each having opposed inner surfaces that are formed with longitudinally spaced apart vertically oriented ribs that terminate in substantially flat surfaces to abut against one another to serve as a concrete wall form. A second embodiment includes a pair of spaced apart elongated expanded polystyrene sidewalls and divisional members with flat sides which are attached to said sidewalls to serve as a concrete wall form. The ribs define channels for receiving concrete poured therein to form a composite polystyrene and concrete wall structure in the first embodiment and the divisional members serve the same function in the second embodiment.

A concrete form building system as recited in claim 1 , wherein said first and second sidewalls have top and bottom edges and said top ends of each of said plurality of divisional members are spaced apart from said top edges of said sidewalls and said bottom ends of each of said plurality of divisional members are spaced apart from said bottom edges of said sidewalls to provide upper and lower concrete receiving areas that are in communication with the channels between each of said plurality of divisional members.
Claim 4
Dependent Claim 70 words
A concrete form building system as recited in claim 1 , wherein divisional members are cut such that an interruption of divisional members results and a solid spacer member is placed within said interruption of the divisional members and said solid spacer member is abutted against and adjacent to said inner surfaces of said sidewalls, to provide pre-formed places for windows or doors in said sidewalls prior to pouring concrete.
Claim 5
Dependent Claim 24 words
A concrete form building system as recited in claim 3 , wherein said system further comprises elongated rebar positioned within said spaced apart channels.
Claim 6
Dependent Claim 39 words
A concrete form building system as recited in claim 3 , wherein said system further includes a rebar clip attached to each of said rebar, said clip having a winged configuration for properly positioning said rebar within said channels.
Claim 7
Dependent Claim 50 words
A concrete form building system as recited in claims 4 , wherein said first and second sidewalls each have an outer surface and said outer surface of at least one of said first and second sidewalls has spaced apart vertically oriented recesses and furring strips are positioned in said recesses.
Claim 8
Dependent Claim 29 words
A concrete form building system as recited in claim 5 , wherein said outer surface of at least one of said sidewalls is laminated to a plastic sheet off-site.
Claim 9
Dependent Claim 169 words
A concrete form building system comprising: a) a first elongated expanded polystyrene sidewall; b) a second elongated expanded polystyrene sidewall; c) said sidewalls each having opposed inner surfaces and generally planar outer surfaces; d) divisional members comprising top and bottom ends and four side surfaces wherein two of the side surfaces are generally planar and oriented opposite one another and the third and fourth side surfaces are each of two planar segments positioned at an angle respective to each other such that a cross section of each divisional member has a mid point narrower than the length of its two generally planar sides; e) means for attaching one of said generally planar side surfaces of each of said divisional members to one of the opposed inner surfaces of said sidewalls and the other of said generally planar side surfaces to the other of said opposed inner surfaces to provide a concrete wall form with a series of spaced apart channels between said divisional members for receiving concrete poured therein.
Claim 10
Dependent Claim 169 words
A concrete form building system comprising: a) a first elongated expanded polystyrene sidewall; b) a second elongated expanded polystyrene sidewall; c) said sidewalls each having opposed inner surfaces and generally planar outer surfaces; d) divisional members comprising top and bottom ends and four side surfaces wherein two of the side surfaces are generally planar and oriented opposite one another and the third and fourth side surfaces are each of two planar segments positioned at an angle respective to each other such that a cross section of each divisional member has a mid point narrower than the length of its two generally planar sides; e) means for attaching one of said generally planar side surfaces of each of said divisional members to one of the opposed inner surfaces of said sidewalls and the other of said generally planar side surfaces to the other of said opposed inner surfaces to provide a concrete wall form with a series of spaced apart channels between said divisional members for receiving concrete poured therein.
