Abstract
A form extender for concrete construction comprises a sheet metal body with multiple bends forming a tension-based attachment portion. This attachment portion can be removably secured to a form member such as a segment of lumber. The sheet metal body is shaped to extend beyond the form member, providing a form extension surface. This surface maintains continuity with the form member during concrete operations.
Claims19
A form extender for concrete construction, comprising:
- a first portion of sheet metal extending along a length dimension and having a height in a vertical direction;
- a second portion of the sheet metal connected to a top edge of the first portion at a first bend, the second portion oriented at a first interior angle relative to the first portion;
- a third portion of the sheet metal connected to the second portion at a second bend, the third portion oriented at a second interior angle relative to the second portion, wherein the third portion extends in the vertical direction;
- and
- a fourth portion of the sheet metal connected to the third portion at a third bend, the fourth portion oriented at an exterior angle relative to the third portion, wherein the third bend defines a grip space between the third portion and the first portion;
- wherein the second portion, third portion, and grip space create a tension-based attachment portion that is configured to removably secure to at least one form member of a concrete form that is positioned within the grip space;
- and
- wherein the first portion provides a form extension surface that is configured to maintain continuity with the at least one form member.
5 more elements
A method of using a form extender for concrete construction, comprising:
- arranging multiple form members in a concrete form;
- identifying a gap between a first form member and a second form member of the multiple form members;
- and
- applying a form extender to the gap, wherein the form extender uses a tension-based attachment to attach to the first form member and the second form member.
1 more element
A method of manufacturing a form extender, comprising:
- selecting a sheet metal with a first thickness;
- cutting the sheet metal to define a planar blank having a length dimension and a height dimension;
- performing a first bending operation on the planar blank to create a first bend that defines a first portion and a second portion, the first portion having the height dimension;
- performing a second bending operation on the planar blank to create a second bend that defines a third portion connected to the second portion;
- and
- performing a third bending operation on the planar blank to create a third bend that defines a fourth portion, wherein the third bend defines a grip space between the third portion and the first portion, wherein the second portion, third portion, and grip space create a tension-based attachment portion that enables the form extender to be removably secured to at least one form member of a concrete form.
