Building corner form structure

Claim 1

A reusable building form structure for use in forming a settable corner column positioned between and integrally interconnecting a pair of adjacent angularly oriented preformed wall panels during construction of a tilt-up wall building and the like, said corner column being formed from a mass of settable construction material introduced into a space defined by said form structure and edge surfaces of said wall panels, said form structure comprising A. a first integral unitary preformed rigid and self-supporting elongated channel shaped form to be positioned in engagement with the outer surface of each of said pair of wall panels to bridge said space between said edges thereof, and B. a second integral unitary preformed rigid and self-supporting elongated channel shaped form to be positioned in engagement with the inner surface of said pair of wall panels to bridge said space between the edges thereof, C. said forms when engaged with said inner and outer surfaces of said wall panels closing off said space between said wall panel edges for a substantial portion of their height to receive and maintain therebetween said mass of settable construction material therein which is to form said corner column of said building between said wall panels, D. said first form comprising 1. at least two angularly oriented side walls integrally connected with each other, and 2. extensions of said side walls which are engageable with said outer surfaces of said wall panels when said first form is positioned between said wall panels to bridge said space between said edges thereof, 3. said side walls converging outwardly relative to each other and being integrally connected with each other along an edge portion of said first form, E. said second form comprising 1. a base wall, and 2. extensions of said base wall which are engageable with said inner surfaces of said wall panels when said second form is positioned between said wall panels to bridge said space between said edges thereof, 3. said extensions being angularly oriented relative to each other and to said base wall and diverging outwardly relative to said base wall, and F. means provided on said side walls of said first form and along said base wall of said second form for reinforcing each such form and for facilitating operatively connecting said forms together to receive said settable construction material therebetween, G. said space between said wall panel edges and said forms being generally enclosed thereby to receive said mass of settable construction material therein which defines said corner column and interconnects said wall panels into a unitary wall assembly.
