EXPANSION JOINT SEALING ASSEMBLY FOR CURB AND ROADWAY INTERSECTIONS

摘要

An expansion joint sealing assembly of the type employing a flexible membrane extending between two relatively rigid elongated elastomeric pads is adapted to seal the gap in the area where a curb and roadway portion of the deck intersect. The assembly is especially useful in situations where the gap extends at a skew angle across the roadway, so that the line of intersection between the curb and roadway portions of the deck, along which the sealing assembly must be bent, is not perpendicular to the longitudinal dimension of the sealing assembly. This creates a complex bending angle for the flexible membrane portion of the seal. In brief terms, the problem is solved by providing laterally extending convolutions in the side edge portions of the membrane and a locking rib on the top of each convolution which fits into an appropriate slot in the elastomeric pad to which each side edge portion of the membrane is connected.
