BRIDGE ERECTION METHOD AND LAUNCHING MACHINE FOR BRIDGE ERECTION

TAKAO TOMOYUKI / MINEYAMA YUKI / AZUMA HIROTOSHI / TACHIBANA HAJIME

To provide a bridge erection method and launching machine for bridge erection that can easily and quickly adjust a deflection of the launching machine.SOLUTION: A launching machine 1 comprises a launching machine main body 10 and a supporting member 20 with one end thereof rotatably connected to a tip side of launching machine main body 10 and having the length longer than a vertical direction interval between the tip side of launching machine main body 10 displaced downward due to a deflection and a bridge pier 3 of a bridging point. In a bridge erection method, the other end of supporting member 20 is rotatably fixed onto the bridging point and while sending out a bridge girder 2 and rotating the supporting member 20, the tip side of launching machine main body 10 is displaced upward by pushing up with the supporting member 20. This eliminates the need for placing equipment for pushing up the tip side of the launching machine main body 10 on the bridge pier 3 separately or eliminates the need for pulling up the tip side of the launching machine main body 10 from the ground by a large crane, and thereby deflection of the launching machine 1 can be easily and quickly adjusted.SELECTED DRAWING: Figure 10

【課題】手延べ機の撓みの調整を容易且つ迅速に行うことのできる橋梁架設方法及び橋梁架設用手延べ機を提供する。【解決手段】手延べ機本体１０の先端側に一端を回動自在に連結され且つ撓みにより下方に変位した手延べ機本体１０の先端側と架け渡し先の橋脚３との鉛直方向の間隔よりも大きい長さを有する支持部材２０の他端を架け渡し先に回動自在に固定するとともに、橋桁２を送り出して支持部材２０を回動させながら手延べ機本体１０の先端側を支持部材２０で押し上げて上方へ変位させるようにしたので、手延べ機本体１０の先端側を押し上げるための機材を橋脚３上に別途設置したり、或いは地上から大型クレーンで手延べ機本体１０の先端側を引き上げる必要がなく、手延べ機１の撓みの調整を容易且つ迅速に行うことができる。【選択図】図１０
