Abstract
Abstract A reusable form assembly for casting walls and footings from concrete or other suitable material consisting of corner-forming members, side-forming panel members and main support members disposed between successive panel members, all detachably bolted together to provide a selected form length for forming one surface of the wall or footing. If a form is to be used in forming the other surface of the wall, a similar arrangement of corner-forming members, panel members, and main support members is provided in suitable length and in laterally spaced relationship to the first mentioned form assembly. A dovetail joint arrangement is provided between the corners and the cooperating side panels and between the panels and cooperating support members to effectively align the cooperating members and hold them in true alignment until the form is disassembled. Additional longitudinally extending support wales or bars are secured to the exterior of each of the wall-form assemblies to prevent outward bulging thereof from the force of the poured concrete.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
177 words
A wall form assembly comprising upright panel members and support members which alternate and are removably secured together at adjacent vertical edges: each of said members being of elongaged tray-like form having a main panel, an outwardly extending angular connector flange at each of the opposed side edge extremities of the panel which extends vertically thereof and angles outwardly relative to the panel, and a lateral inwardly extending stop flange on the outer extremity of each of said connector flanges; the two connector flanges on each of said support members at its extremities angularly converging outwardly and the two connector flanges on each of said panel members diverging outwardly; said alternating panel members and support members having their connector flanges at complemental angles so that adjacent connector flanges are in contact with the stop flanges of the support members outwardly of and in contact with the stop flanges of said panel members to locate the inner surfaces of the panels of the respective members relatively, said contacting connector flanges having aligning openings which receive removable clamping bolts.
Claim 2
Dependent Claim
177 words
A wall form assembly comprising upright panel members and support members which alternate and are removably secured together at adjacent vertical edges: each of said members being of elongaged tray-like form having a main panel, an outwardly extending angular connector flange at each of the opposed side edge extremities of the panel which extends vertically thereof and angles outwardly relative to the panel, and a lateral inwardly extending stop flange on the outer extremity of each of said connector flanges; the two connector flanges on each of said support members at its extremities angularly converging outwardly and the two connector flanges on each of said panel members diverging outwardly; said alternating panel members and support members having their connector flanges at complemental angles so that adjacent connector flanges are in contact with the stop flanges of the support members outwardly of and in contact with the stop flanges of said panel members to locate the inner surfaces of the panels of the respective members relatively, said contacting connector flanges having aligning openings which receive removable clamping bolts.
Claim 3
Dependent Claim
147 words
A wall form assembly according to claim 1 including an upright corner form member adjacent the outermost panel member, the panel member being between it and the support member: said corner member being of elongated angular form having two main walls joined together at an angle joint and being relatively angularly disposed, an outer vertically extending connector flange on the outer extremity of each of said side walls which angles outwardly relative to the wall and a lateral inwardly extending stop flange on the outer extremity of each of said connector flanges; said corner member having its angularly disposed connector flange complemental to the adjacent flange of said panel member with its stop flange outwardly of the stop flange on said adjacent connector flange of the panel member, said adjacent connector flanges of the said corner member and panel member having aligned openings which receive clamping boltS.
Claim 4
Dependent Claim
62 words
A wall form assembly according to claim 1 in which: each of the stop flanges of said support members carries a bar-receiving socket member with the socket members disposed substantially at the same level above the lower ends of the support members; and a re-inforcing bar fitted into said socket members and extending longitudinally of the wall form to prevent outward bulging.
Claim 5
Dependent Claim
46 words
A wall form assembly according to claim 3 in which: each of said socket members is provided by a clip attached to each flange and having an angular socket opening upwardly; and said bar is of complemental angular cross section and is dropped into said sockets.
Claim 6
Dependent Claim
47 words
A wall form assembly according to claim 1 in which: each of said support members and panel members is provided with an abutment flange at its upper and lower ends to facilitate bolting identical vertical sections together and the lowermost section to a footer or similar support.
Claim 7
Dependent Claim
70 words
A wall form assembly according to claim 1 in which: each of said support members is provided with an anchoring plate extending between the stop flanges substantially flush therewith; and stakes adapted to be driven into the ground to anchor the respective support members; said stakes and said plates having aligning openings which receive anchoring bolts when the support members are disposed with their plates in contact with the stakes.
