Movement limiting device for bridge bearing

Abstract

A movement limiting device of a bridge bearing is provided in which the horizontal strength in the longitudinal direction and the perpendicular direction of a bridge when limitation in movement is cancelled can be suitably separately set. A rubber bearing 64 is interposed between an upper shoe plate 60 and a lower shoe plate 62. The upper shoe plate 60 has a notch 72 formed in a side thereof. A side block 80 has two projections 82, 84, which are formed integrally with the side block 80 to project upwardly. The side block 80 has a plurality of bolt through holes 86, which are formed therein on both end sides of the projections 82 and 84, and another bolt through hole 86, which is also formed in a concave portion 83 between the projections 82 and 84. Bolts 78 fix the side block to the lower shoe plate 62. Upper portions of the projections 82, 84 are positioned in the notch 72 such that there are spaces between the projections 82, 84 and both ends 72a, 72b of the notch 72, respectively, just for allowing limited movement.
