ARCH BRIDGE CONSTRUCTION METHOD
To provide an arch bridge construction method and the like that enables easy construction of an arch bridge.SOLUTION: An arch bridge having a stiffening girder and an arch member 14 is constructed so as to project laterally from a bridge pier. The arch member 14 is constructed by placing concrete on a formwork 5 arranged on a formwork support part 4 which is supported by a support member 7 from the stiffening girder above the formwork support part 4. The arch member 14 is supported by a diagonal member 16 different from the support member 7 from the stiffening girder therebehind. When placing concrete, one end of a PC cable 161a, which is the lower end of the diagonal member 16, is buried in the concrete. After placing the concrete, the diagonal member 16 is tensioned.SELECTED DRAWING: Figure 6
【課題】アーチ橋の施工を容易に行うことのできるアーチ橋の施工方法等を提供する。【解決手段】補剛桁とアーチ部材１４を有するアーチ橋を、橋脚から側方へと張り出して行くように構築する。アーチ部材１４は、型枠支持部４をその上方の補剛桁から支持材７で支持した状態で、型枠支持部４の上に配置された型枠５にコンクリートを打設することで構築する。アーチ部材１４はその後方の補剛桁から支持材７とは別の斜材１６で支持させる。コンクリートを打設する際は斜材１６の下端部であるPCケーブル１６１ａの一端をコンクリートに埋設しておき、コンクリートを打設した後に、斜材１６を緊張する。【選択図】図６
