Title:
BRIDGE BEARING FOR ANTI-SEISMIC AND SEISMIC ISOLATION REINFORCEMENT, AND CONSTRUCTION METHOD FOR REPLACING BRIDGE BEARING
Document Type and Number:
WIPO Patent Application WO/2020/235981
Kind Code:
A1
Abstract:
The present invention relates to a bridge bearing for anti-seismic and seismic isolation reinforcement and a construction method for replacing a bridge bearing, wherein, with respect to horizontal and vertical loads applied to a bridge at ordinary times and horizontal, vertical, and pullout loads applied to a bridge during an earthquake, the bridge bearing can sufficiently support loads generated at ordinary times and during an earthquake even when the embedment length of an anchor or anchor socket of the bridge bearing is short. The construction method includes an existing bridge bearing removal step, a bridge support plate placement step, a bridge support plate fixation step, a bridge bearing installation step, an anchor socket fixing plate coupling step, and a construction finishing step of pouring anti-seismic mortar. The bridge support plate is fixed to iron bars of a coping to be integrated with the iron bars, and then the bridge bearing is replaced. Accordingly, anti-seismic and seismic isolation properties can be obtained by a sufficient supporting force even when the length of the anchor socket is short, and moreover, even when the bridge bearing is replaced again, the efficiency of the replacement construction can be improved and sufficient anti-seismic and seismic isolation performance may be exhibited. In addition, sliding of the bridge bearing is prevented so as to improve resistance to horizontal force, and the density of the anti-seismic mortar can be increased by applying the anti-seismic mortar.
