BRIDGE BEARING APPARATUS

摘要

A bridge bearing apparatus is provided to amply secure the support rigidity about the horizontal force by installing the coupler at the place where the load of the bridge upper plate is concentrated. A bridge bearing apparatus is composed of a sole plate(100) installed with mount key grooves(110,120) recessed on the lower surfaces; an upper plate(200) mounted with a base key groove(210) recessed on the upper surface; constraint keys(310,320) fitted in the mount and base key grooves to restrict the sole and upper plates not to be dislocated and to horizontally separate the upper plate from the sole plate; a lower plate(400) fixed at the pier; and an absorbing member unit(500) formed with plural members(520) mounted between the upper and lower plates to absorb the vibration and the horizontal force transferred the upper plate of the bridge. The restraint keys contain the first restraint key longitudinally installed, and the second restraint key horizontally installed.
