FORM SUPPORT STRUCTURE, AND BRIDGE CONSTRUCTION METHOD
To provide a form support structure and the like that facilitates height adjustment of a support work.SOLUTION: A form support structure that supports a form when placing concrete for an arch member of an arch bridge with a support work 3, comprises: a support girder 1 provided in the direction of the bridge axis; the support work 3 provided on the support girder 1 and over the entire bridge axis direction of the support girder 1; and a push-up part 2 that is provided below the support girder 1 and applies an upward force in the vertical direction to a part of the support girder 1 in the bridge axis direction. The push-up part 2 has: a piece material 21 whose upper end abuts on the lower surface of the support girder 1; a diagonal member 22 extending diagonally upward from the piece member 21 to both sides and being held at both ends of the support girder 1 in the bridge axis direction; and a jack 24 that applies tension to the diagonal member 22.SELECTED DRAWING: Figure 2
【課題】支保工の高さ調整を容易とする型枠支持構造等を提供する。【解決手段】型枠支持構造は、アーチ橋のアーチ部材のコンクリートを打設する際の型枠を支保工３によって支持するものであり、橋軸方向に設けられた支持桁１と、支持桁１の上に、支持桁１の橋軸方向の全体に亘って設けられた支保工３と、支持桁１の下方に設けられ、支持桁１の橋軸方向の一部に鉛直方向上方の力を加える押上げ部２と、を有する。押上げ部２は、上端が支持桁１の下面に当接するコマ材２１と、コマ材２１から両側へと斜め上方に延び、支持桁１の橋軸方向の両端部で保持される斜材２２と、斜材２２に張力を加えるジャッキ２４と、を有する。【選択図】図２
