BRIDGE AND BRIDGE CONSTRUCTION METHOD
To provide a bridge and a bridge construction method capable of lowering the height from a pier of a bridge to a floor slab.SOLUTION: A bridge 10 is provided with a plurality of main girders 15 supporting a floor slab 16, bridge piers 11 supporting the main girders 15, and seismic isolation bearings for connecting the bridge piers 11 and the main girders 15. The base isolation bearing is provided with support members 21 and tension members 26. The support member 21 has an overhanging part 21a protruding at a position higher than a lower part of the main girder 15, and is disposed around each main girder 15 on the bridge pier 11. The tension member 26 connects a lower part of the main girder 15 arranged between the plurality of support members 21 and the overhanging part 21a in a separated state.SELECTED DRAWING: Figure 1
【課題】橋梁の橋脚から床版までの高さを低くすることができる橋梁及び橋梁の構築方法を提供する。【解決手段】橋梁１０は、床版１６を支持する複数の主桁１５と、主桁１５を支持する橋脚１１と、橋脚１１と主桁１５とを接続する免震支承とを備える。免震支承は、支持部材２１と引張部材２６とを備える。支持部材２１は、主桁１５の下部より高い位置で突出した張出部２１ａを有し、橋脚１１上において各主桁１５の周囲に配置される。引張部材２６は、複数の支持部材２１の間に配置された主桁１５の下部と張出部２１ａとを離間した状態で連結する。【選択図】図１
