Patent ID: 6922962

Claim:
An insulating concrete form for receiving poured concrete, comprising: a first insulating panel formed from expanded foam, having a first interior surface, an upper surface, a lower surface, a proximal end, and a distal end; a second insulating panel formed from expanded foam, having a second interior surface facing said first interior surface of said first insulating panel, an upper surface, a lower surface, a proximal end, and a distal end; and at least one tie bracket spanning, connecting, and spacing apart said first insulating panel and said second insulating panel, wherein said first interior surface and said second interior surface have principally flat surfaces comprising a series of male extensions protruding therefrom collectively to thereby form a void between said first interior surface and a void between opposing extensions of the first and second panels and said second interior surface such that a plurality of spaced apart posts, a plurality of spaced apart beams disposed to intersect said posts, and a plurality of webs spanning and joining adjacent said posts and adjacent said beams are formed when said void is filled with poured concrete and the concrete cures, and wherein said upper surface of said first insulating panel has a first interlocking member formed therein and said lower surface of said first insulating panel has a second interlocking member formed therein, wherein said first interlocking member and said second interlocking member are disposed to oppose parallel movement of one said insulating concrete form with respect to a second said insulating concrete form disposed in stacked, interlocked relationship therewith.
