The present invention relates to a rubber support for a bridge, which comprises: a lower plate (220) placed on a bridge lower structure (200) and fixated by an anchor; an upper plate (120) supporting a lower surface of a bridge upper structure (100); and a rubber member (300) arranged between the upper and the lower plate (120, 220), wherein a plurality of reinforcing plates (302) are vertically arranged. An upper and a lower fixing plate (320, 340) of a metal material is respectively and integrally formed to be clamped with the upper and the lower plate (120, 220) on an upper and a lower surface of the rubber member (300). A contact surface (400) to be processed as a round or inclined shape is formed to prevent a phenomenon wherein an edge portion of the upper and the lower fixing plate (320, 340) which is in contact with the rubber member (300) is separated or broken when relative displacement of the rubber member (300) occurs. According to the present invention, a rubber member which forms a rubber support in a bridge can be maintained as a stably fixated state without being separated and broken from an upper and a lower plate which forms an upper and a lower structure of a bridge when a displacement force by an upper structure of a bridge occurs. |
