Compliant Trim for Concrete Slabs

摘要

A compliant trim for use between concrete slabs is disclosed, intended to seal the joints and provide a decorative cover over the forms. The compliant trim is placed on the forms prior to the pouring of concrete. The compliant trim contains features which anchor the compliant trim to the slab at numerous points along its length, thereby constraining the compliant trim against any shrinkage effects, and doing so in a manner that introduces minimal stress concentration into the slabs. When the compliant trim is anchored to both of the adjacent slabs, it is capable of following slab motions due to thermal expansion or other environmental effects. The surface of the compliant trim may be used to support the screed. Additionally, the compliant trim may be used to produce a chamfered or radius edge, thereby eliminating the need to radius-trowel the slab.

主权项

1) A compliant trim for concrete, applied to the top edge of or prior to the pouring of concrete, comprised of:
a) a cover, situated on the top edge of said forms, and b) an anchoring means, located on one or both sides of said forms, said anchoring means surrounded by said concrete during said pouring, said anchoring means providing mechanical interference against motion along the length of said compliant trim once said concrete has solidified.
