EXPANSION JOINT FOR BRIDGE

摘要

An expansion joint structure for bridge is provided to reduce the manufacturing cost of the waterproof coupling and improve waterproof performance by enhancing connection between the waterproof coupling and the expansion joint. An expansion joint structure for bridge comprises an expansion joint in which a connection groove is formed and a waterproof coupling(20) which is formed in a symmetrical shape and includes a connection part(21), a sub connection hole(23), and a folding groove(22) by which the waterproof coupling is folded by half. The connection part of the waterproof coupling consists of a first connection part(21a) and a second connection part(21b) and is combined in the connection groove.
