Frangible concrete-joint sealant package

Abstract

Abstract A frangible package containing sealant for sealing joints between adjacent construction panels or slabs composed of such materials as concrete, masonry units and curtain wall, includes an elongated tube-like bar having a pair of continuous lines of weakness extending longitudinally along its entire length on opposite sides thereof to enable the bar to be broken apart longitudinally along the lines and thus to release the joint sealant disposed within the hollow interior of the bar, and a pair of end walls for sealing the sealant within the bar. The bar is adapted to be fastened to and extend along the top edge of an expansion joint filler strip, and a pair of external up-turned flanges extending from opposite sides of the bottom portion of the package anchor it to the adjacent slabs after they are positioned on opposite sides of the package and strip so that the top portion of the package may be pulled away readily from its bottom portion leaving it in place to help support the sealant. A bottom wall of the bar is bowed inwardly throughout its length to cause the sealant to assume a complementary shape so that its advantageous shape facilitates its expansion and contraction. When the top portion of the package is separated from its bottom portion, the sealant flows into sealing engagement with the adjacent side edges of the slabs to seal the joint therebetween. When used to seal concrete joints, the top wall of the bar has an external flat surface to serve as a screed when finishing the adjacent concrete surfaces.
