Abstract
This invention provides an adjustable, removable, reusable masonry tool for retaining expansion material employed in concrete work. The tool includes a plurality of elongated, substantially U-shaped caps which retain the expansion material, the caps being slidably engaged together for adjustment of the tool's length.
Claims11
An adjustable, removable, reusable tool for retaining elongated expansion material vertically on edge across a defined space intended to receive concrete which comprises
- a plurality of elongated, substantially U-shaped caps channeled wide enough to accept the expansion material and of aggregate length greater than that across the defined space, said caps including a subunit having three caps, a central cap having first and second ends and being channeled to a different width than said outer caps, said outer caps being nested within said first and second ends of said central cap, said caps being slidably engageable together to be inverted over the expansion material with the legs of the U downwardly extended and lengthened across the space,
- whereby said tool retains the expansion material in place while concrete is poured but can then be removed, adjusted and reused across a similar or different space.
An adjustable, removable, reusable tool for retaining expansion material vertically on edge across a space defined by forms intended to receive concrete which comprises
- a set of three elongated, substantially U-shaped caps, a central cap and two outer caps, said caps being channeled to accept the expansion material and of aggregate length greater than that across the defined space, said central cap having first and second ends and being channeled to a different width than said outer caps, said outer caps being nested within said first and second ends of said central caps, thereby permitting said caps to be slidably engaged together to be inverted over the expansion material with the legs of the U downwardly extended and lengthened across the space, together with
- ears with holes joined to said outer caps adjacent the forms for securing said caps with respect thereto with fastenings.
A method for incorporating expansion material at a desired joint location in concrete paving to be poured into a defined space which comprises
- providing a tool which includes a plurality of elongated, substantially U-shaped caps channeled wide enough to accept the expansion material and of aggregate length greater than that across the defined space, said caps including a subunit having three caps, a central cap having first and second ends and being channeled to a different width than said outer caps, said outer caps being nested within said first and second ends of said central cap, said caps being slidably engaged together:
- inverting said tool over the expansion material with the legs of the U downwardly extended and lengthened across the space to retain the expansion material on edge at the desired joint location;
- pouring concrete on both sides of the joint;
- and then
- removing said tool before the concrete hardens.
Ad adjustable, removable, reusable tool for retaining elongated expansion material vertically on edge across a defined space intended to receive concrete which comprises
- a plurality of elongated, substantially U-shaped caps channeled wide enough to accept the expansion material and of aggregate length greater than that across the defined space, said caps including a subunit having three caps, a central cap having first and second ends and being channeled to a different width than said outer caps, said outer caps being similarly nested, one within the other, with said first and second ends of said central cap, said caps being slidably engageable together to be inverted over the expansion material with the legs of the U downwardly extended and lengthened across the space,
- whereby said tool retains the expansion material in place while concrete is poured but can then be removed, adjusted and reused across a similar or different space.
