BRIDGE BEARING FOR ANTI-SEISMIC AND SEISMIC ISOLATION REINFORCEMENT, AND CONSTRUCTION METHOD FOR REPLACING BRIDGE BEARING
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.
La présente invention concerne un appui de pont pour un renforcement d'isolation antisismique et sismique et un procédé de construction pour remplacer un appui de pont, dans lequel, par rapport à des charges horizontales et verticales appliquées à un pont à des moments ordinaires et à des charges de traction horizontales, verticales et de traction appliquées à un pont pendant un tremblement de terre, l'appui de pont peut supporter de manière suffisante des charges générées à des moments ordinaires et pendant un tremblement de terre même lorsque la longueur d'enfoncement d'un ancrage ou d'une douille de l'appui de pont est courte. Le procédé de construction comprend les étapes consistant à retirer l'appui de pont existant, à placer une plaque de support de pont, à fixer une plaque de support de pont, à installer un support de pont, à accoupler une plaque de fixation de douille et à finir la construction en versant du mortier anti-sismique. La plaque de support de pont est fixée à des barres de fer d'une chape à intégrer aux barres de fer, puis le support de pont est remplacé. Par conséquent, des propriétés d'isolation antisismique et sismique peuvent être obtenues par une force de support suffisante même lorsque la longueur de la douille est courte, et même en outre, lorsque l'appui de pont est de nouveau remplacé, l'efficacité de la construction de remplacement peut être améliorée et une performance d'isolation antisismique et sismique suffisante peut être obtenue. De plus, le coulissement de l'appui de pont est empêché de façon à améliorer la résistance à la force horizontale, et la densité du mortier anti-sismique peut être augmentée par l'application du mortier anti-sismique.
