BRIDGE BODY AND CONSTRUCTION METHOD OF BRIDGE BODY

To provide a temporary bridge which is easy to be built and removed and flexibly absorbs seismic vibrations.SOLUTION: A bridge body has an upper structure including bridge slabs and a lower structure which is provided below the upper structure and includes at least a sufficient number of piers to maintain the posture of the upper structure. The piers are connected to each other via joints. A first pier, constituting the joints, has a first surface at its top, of which the peripheral parts rise upward, and a second pier, constituting the joints, has a second surface that bulges downward at its bottom, the second surface located on the first surface.SELECTED DRAWING: Figure 1 【課題】設置および撤去が容易でありながら、地震震動に対して柔軟に吸収する仮設橋を提供する。【解決手段】床版を含む上部工と、この上部工の下側に設けられ、少なくとも前記上部工の姿勢を保持できる数の橋脚を含む下部工とを有し、前記橋脚は関節を介して連結され、前記関節を構成する第１の橋脚は、その上部に周辺部が上方に迫り上がる第１の面を有し、前記関節を構成する第２の橋脚は、その下部に下方に膨出する第２の面を有し、前記第２の面は前記第１の面上に位置している。【選択図】図１
