ABSTRACT:
An improved expansion joint assembly (10, 70) is provided for bridging an expansion void (12, 72) between adjacent, relatively shiftable structural sections (14, 6, 74, 76). The assembly (10, 70) includes a pair of supports (18, 20, 78, 80) respectively secured to the sections (14, 16, 74, 76), as well as a bridging member (22, 82) operatively engaging the supports (18, 20, 78, 80). A resilient compressible filler (24, 128, 130) is located between a bridging member (22, 82) and adjacent portions of the supports (18, 20, 78, 80). The filler (24, 128, 130) is preferably in the form of a compressible, resilient body including walls (62) defining a series of openings (64), so that the filler can accommodate significant movement without bulging or failure.
