<p>PURPOSE: A seismic support for bridge is provided to effectively curb left and right rotation compared with forward and backward rotation while the forward and backward rotation and left and right rotation of slab is stably supported. CONSTITUTION: A seismic support for bridge comprises a lower plate unit(110), a port(120), elastic rubber(130), a piston(140), and a slab unit(150). The port is settled on the lower plate unit. The elastic rubber forms a panel, whose a transversal length perpendicular to throttling is longer than a longitudinal length. The elastic rubber is settled on the port. The piston is settled on the elastic rubber and presses it. The slab is settled on the piston.</p> |
