ABSTRACT:
A composite expansion joint assembly having a pair of edge members, a plurality of elongated resiliently yieldable sealing elements, rigid structural members interposed between adjacent sealing elements and laterally spaced support bars for the structural members. Equalizing springs acting directly upon the structural members independently of the support bars are compressed by movement of the structural members away from each other and from the edge members as the sealing members open, providing equalizing forces to maintain equidistant spacing between the structural members whether they are laterally slidable on the support bars in a single support bar system or are fixed to the support bars in a multiple support bar system.
