CUSHION SUPPORT FOR BRIDGE

摘要

An elastic support for a bridge is provided to form a reinforcement part at the edge of a rubber pad compensating for the horizontal displacement of a bridge so that the life span of the rubber pad is extended. An upper plate(10) is fixed to the lower portion of an upper structure of a bridge. A lower plate(20) is fixed to a lower structure of the bridge. A rubber pad(30) is thermally bonded to a sub-plate fixed to the upper plate(10) and the lower plate(20). A reinforcement portion prevents the contact surface between the rubber pad(30) and the sub-plate from being delaminated when the horizontal displacement of the upper and lower structures occurs. The reinforcement portion is formed along the circumference of the rubber pad(30) at the end portion of the edge of the sub-plate while forming a concaved surface.
