Patent ID: 8186128

Claim:
A method of constructing a building having multiple storeys using insulated concrete forms, said forms having two layers of foam spaced apart from one another by ties to define a core, each of said forms having an inside foam layer and an outside foam layer, said forms being stackable to form a vertical wall, said method comprising stacking said forms for an insulated concrete form storey with openings for any windows and doors, with an uppermost row of forms for each storey having an inside foam layer that is shorter than an outside foam layer by a distance that is substantially equal to a thickness of a floor to be installed at a top of said inside foam layer, installing reinforcing rods and pouring fresh concrete between and in contact with said inside foam layer and said outside foam layer to fill said core with said fresh concrete substantially up to said top of said inside foam layer of said uppermost row of forms, allowing said fresh concrete to cure sufficiently to support the weight of said floor to enable said floor to be installed, installing supports for said outside foam layer of said uppermost row of forms for each storey to straighten and support said outside foam layer when fresh concrete is being poured against said outside foam layer of said uppermost row of forms, installing said floor on said sufficiently cured concrete and repeating said method for each subsequent storey, at least partially imbedding said supports in said concrete and locating said supports to leave said supports in place when said vertical wall has been completed.
