Abstract

A reusable building form structure defined by opposed, rigid, preformed, self-supporting form members, and a method of utilizing the same with previously erected building wall panels, to produce a corner column defined by settable construction material introduced into the space delimited by the wall panels and the corner form structure. Improved alignment means are provided on adjacent form members to insure proper interengagement of abutting form members vertically arranged endto-end to permit formation of corner columns of varying heights.

Claims

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.

2. the flanges of said respective sections being in face-to-face contact with each other, and

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

4. two separable form sections operatively connected with each other along said edge portion at a location spaced from the respective extensions of said side walls.

5. The form structure of claim 4 in which said side walls of said first form extend generally normal to each other and form generally a right angle therebetween.

6. The form structure of claim 1 in which said first form further comprises

7. The form structure of claim 6 in which each of said form sections includes a. one of said side walls and one of said extensions therein.

8. The form structure of claim 6 in which said separable form sections include a. outwardly directed flanges in face-to-face contact with each other, and b. removable fasteners engaged with said flanges for maintaining said form sections together.

9. The form structure of claim 22 which further includes F. means adjacent the top of each of said first and second forms for operatively inter-connecting each such form with a correspondingly contoured form to be positioned in end-to-end vertical alignment therewith.

10. The form structure of claim 9 in which said means for operatively interconnecting correspondingly contoured forms comprises

11. The form structure of claim 1 in which said first form is generally V-shaped in cross-section.

12. The form structure of claim 1 in which said first form is defined by two separable form sections operatively connected with each other.

13. The form structure of claim 12 in which each of said form sections includes
