Abstract

See full text

A gasket for a flush expansion joint cover comprises a longitudinally continuous central body portion and two longitudinally continuous side portions, one at either transverse edge of the central body portion. The central body portions and the side portions are comprised of a colorable thermoplastic rubber and are co-extruded to form an integral gasket structure. The side portions, which are adapted to keylock with mating grooves in structural members of the expansion joint cover, are harder than the central body portion to enhance retention of the gasket in place during use. The central body portion has a cellular core structure and a slightly concave upper surface to remain substantially smooth and flush with adjacent surfaces throughout the complete movement cycle of the expansion joint.
