Insulated concrete form

An insulated concrete form for forming a poured concrete wall, said form having a first vertical surface and a second vertical surface held in a spaced-apart parallel relationship with said first vertical surface by a plurality of elongated tie members attached perpendicularly to both said first and said second surfaces;

• said first vertical surface is a single-sided concrete formwork comprising a plurality of plywood boards having each a plurality of latch members for respectively engaging with a first end of each of said tie members;
• said second vertical surface comprising a plurality of juxtaposed insulation panels and a plurality of elongated vertically aligned connecting members having flange means respectively enclosing two adjacent edges of a bordering pair of said juxtaposed insulation panels;
• said flange means having an I-shaped cross-section having a first flange member aligned along an exterior surface of said insulation panels relative to said form a second flange member aligned on the inside surface of said insulation panels relative to said form, and a first web member aligned into a gap between said two adjacent edges for perpendicularly joining said first and said second flange members;
• said connecting members further having coupling means for retaining a second end of each of said tie members and for retaining said insulation panels in a forming-resistive manner in said spaced-apart parallel relationship with said plywood boards;
• said coupling means being held to and spaced apart from said second flange member by a second web member, and said second web member being narrower in cross-section than a corresponding cross-section of said coupling means;
• whereby when uncured concrete is poured thereinto, said insulation panels remain in said spaced-apart parallel relationship with said plywood boards, and when said concrete is cured, said insulation panels remain bonded to said concrete wall with said coupling means being enclosed in said concrete wall.
