CONCRETE FILLING JIG AND CONCRETE FILLING METHOD
To provide a concrete filling jig or the like capable of suitably performing the dropping and filling of concrete.SOLUTION: When a concrete 12 is dropped and filled in a steel pipe 11, the concrete 12 is discharged from a pipe body 41 of a jig 4 toward an inner surface 110 on an opening 112 side of the steel pipe 11 so that the concrete 12 flows down along the inner surface 110. The pipe body 41 is inserted into the steel pipe 11 from the opening 112 of the steel pipe 11, and is bent downward in a substantially arc shape in the steel pipe 11. The pipe body 41 has a substantially circular radial cross-section, and a distal end surface 411 of a bent part 410 faces the inner surface 110. The distal end surface 411 has a shape obtained by cutting the pipe body 41 in a direction inclined with respect to the radial direction. When the vertical cross section is viewed, a distal end 414 on the outer peripheral side of the bent part 410 is located closer to the inner surface 110 than a distal end 413 on the inner peripheral side of the bent part 410.SELECTED DRAWING: Figure 2
【課題】コンクリートの落し込み充填を好適に行うことのできるコンクリート充填用治具等を提供する。【解決手段】鋼管１１内でコンクリート１２の落し込み充填を行う際に、治具４の管体４１から鋼管１１の開口１１２側の内面１１０に向けてコンクリート１２を吐出させ、コンクリート１２が内面１１０を伝って流れ落ちるようにする。管体４１は、鋼管１１の開口１１２から鋼管１１内に挿入され、鋼管１１内で略円弧状に下方に折れ曲がる。管体４１は略円形の径方向断面を有し、折れ曲がり部分４１０の先端面４１１が内面１１０に対向する。先端面４１１は、管体４１を径方向に対し傾斜した方向に切取った形となっており、鉛直方向の断面を見た時に、折れ曲がり部分４１０の外周側の先端４１４は、折れ曲がり部分４１０の内周側の先端４１３よりも内面１１０に近い位置にある。【選択図】図２
