Abstract
A collapsible corner assembly is used in a collapsible form assembly to form a hollow structure, such as a four or five sided hollow concrete structure. One embodiment of the form assembly includes two collapsible corner assemblies, two fixed corner assemblies, and intermediate panels coupled to the corner assemblies. Each collapsible corner assembly preferably includes collapsible side portions and retractable members forming outer corner forming surfaces. To collapse the collapsible corner assembly, the retractable members are retracted and the collapsible side portions are moved inwardly. Collapsing the collapsible corner assemblies allows the form assembly to be removed from the hollow structure.
Claims22
A collapsible corner assembly for use with a form assembly for forming a structure from a moldable material, said collapsible corner assembly comprising:
- a main body including a forming surface;
- first and second collapsible side portions operatively coupled to said main body, each of said collapsible side portions having collapsible forming surfaces aligned with said main body forming surface;
- and
- first and second retractable members operatively coupled to said main body, each of said retractable members having retractable forming surfaces, wherein said main body forming surface, said collapsible forming surfaces, and said retractable forming surfaces form outer corner forming surfaces when said collapsible corner assembly is in an uncollapsed position, and wherein said retractable forming surfaces retract and said main body forming surface and said collapsible forming surfaces form said outer corner forming surfaces when said collapsible corner assembly is in a collapsed position.
A collapsible corner assembly for use with a form assembly for forming a structure from a moldable material, said collapsible corner assembly providing outer corner surfaces to form a corner of said structure, said collapsible corner assembly comprising:
- a main body including a main body forming surface;
- a collapsing mechanism housed within said main body;
- first and second collapsible side portions coupled to said collapsing mechanism, each of said collapsible side portions having collapsible forming surfaces aligned with said main body forming surface;
- and
- first and second retractable members coupled to said collapsing mechanism, each of said retractable members having retractable forming surfaces, wherein said main body forming surface, said collapsible forming surfaces, and said retractable forming surfaces form said outer corner forming surfaces when said collapsing mechanism is in an uncollapsed position, and wherein said retractable forming surfaces retract and said main body forming surface and said collapsible forming surfaces form said outer corner forming surfaces when said collapsing mechanism is in a collapsed position.
A collapsible form assembly for use in forming a structure from a moldable material, said collapsible form assembly comprising:
- at least first and second collapsible corner assemblies for positioning at opposite corners, wherein each of said collapsible corner assemblies include collapsible side portions and retractable members forming outer corner forming surfaces, and wherein said retractable members retract and said collapsible side portions move inwardly to shrink said outer corner forming surfaces;
- and
- at least first and second fixed corner assemblies for positioning at opposite corners, wherein said fixed corner assemblies are adapted to be coupled to said collapsible corner assemblies.
A collapsible form assembly for use in forming a structure from a moldable material, said collapsible form assembly comprising:
- at least first and second collapsible corner assemblies for positioning at opposite corners, wherein each of said collapsible corner assemblies include collapsible side portions and retractable members forming outer corner forming surfaces, and wherein said retractable members retract and said collapsible side portions move inwardly to shrink said outer corner forming surfaces;
- at least first and second fixed corner assemblies for positioning at opposite corners;
- and
- intermediate panels secured between said collapsible corner assemblies and respective said fixed corner assemblies.
