ABSTRACT:
An expansion joint strip seal for use in roadways, bridges, buildings, and the like adapted for use with a pair of elongated, parallel, spaced apart edge members defining a gap therebetween and each of the edge members having a generally C-shaped cavity opening toward said gap. The seal includes mounting beads on each of its longitudinal edges for mounting within the aforesaid edge member cavities and a downwardly folding resilient web member spanning the aforesaid gap and being attached to the mounting beads. Each mounting bead is of tubular construction and includes an outer wall surface configuration generally adapted for matching engagement with said cavity. However, the radius of curvature of the mounting bead outer wall portion in an unstressed, disassembled condition is less than the radius of curvature of the cavity so that upon assembly of the mounting bead within the cavity the outer curved wall portion is forced to assume the curvature of the cavity resulting in a highly effective mounting of the bead. In addition, the wall portion of each mounting bead adjacent to the aforesaid gap is of a S-shaped configuration, the latter acting as a spring to resiliently retain the bead in a firmly mounted disposition during the various degrees of expansion and contraction of the gap defined between the edge members.
