BRIDGE BEARING REPLACEMENT METHOD AND BRIDGE BEARING STRUCTURE
To provide a bridge bearing structure that allows a bearing to be replaced with a small amount of jacking-up.SOLUTION: A replacement method of a bearing 100 being a bridge bearing installed in a substructure such as an abutment 200 or a bridge pier 205 and supporting a superstructure such as a main girder 210, a main truss, and a floor slab, in which the bearing 100 includes: a base plate 150 in contact with the upper surface of the abutment 200 or the bridge pier 205; an elastic load bearing plate 130 corresponding to a bearing body disposed between the base plate 150 and the main girder 210; and a slide plate 110 corresponding to a movement regulating member regulating the lateral movement of the elastic load bearing plate 130. A jack 300 corresponding to a support means is disposed between the abutment 200 or the bridge pier 205 and the main girder 210. While the jack 300 supports a force applied to the elastic load support plate 130, the main beam 210 is jacked up within an allowable range of deformation of the main girder 210, and the slide plate 110 is removed to replace the elastic load support plate 130.SELECTED DRAWING: Figure 1
【課題】僅かなジャッキアップ量で支承を交換可能とする橋梁用支承構造の提供。【解決手段】橋台２００又は橋脚２０５などの下部構造に設置され、主桁２１０や主構、床版などの上部構造を支える橋梁用支承である支承１００の交換方法において、支承１００は、橋台２００又は橋脚２０５の上面部と接するベースプレート１５０と、ベースプレート１５０と主桁２１０との間に配置される支承体に相当する弾性荷重支持板１３０と、弾性荷重支持板１３０の横方向への移動を規制する移動規制部材に相当するスライドプレート１１０を有し、橋台２００又は橋脚２０５と主桁２１０との間に支持手段に相当するジャッキ３００を配置して、ジャッキ３００により、弾性荷重支持板１３０にかかる力を支持しつつ、主桁２１０の変形の許容範囲以下で主桁２１０をジャッキアップし、スライドプレート１１０を撤去することで弾性荷重支持板１３０を交換する。【選択図】図１
