CONCRETE INSTALLATION METHOD
To provide a concrete installation method suppressing concrete material separation in constructing a wall body.SOLUTION: A concrete installation method comprises a concrete supply step of supplying high fluidity concrete through a spacial arrangement pipe 9 arranged in an installation space 5 into the installation space 5. The spacial arrangement pipe 9 includes a plurality of through holes 15 which are formed so as to penetrate a pipe wall portion 13 and which discharges the high fluidity concrete supplied into the pipe, into the installation space 5 that is an outside of the pipe. In the concrete supply step, the spacial arrangement pipe 9 directs its pipe shaft A in a substantial vertical direction, and is installed inside the installation space 5 in a direction where all the through holes 15 satisfy a condition that a half line AB passing a center B of the through hole 15 and horizontally extending with the pipe shaft A as one end crosses an inner wall face 3a of a formwork 3 at an angle larger than 45°.SELECTED DRAWING: Figure 2
【課題】壁体の構築においてコンクリートの材料分離を抑制するコンクリート打設方法を提供する。【解決手段】コンクリート打設方法は、打設空間５に配設される間配り管９を通じて打設空間５内に高流動コンクリートを供給するコンクリート供給工程を備え、間配り管９は、管壁部１３を貫通して形成され管内に供給された高流動コンクリートを管外である打設空間５に排出する複数の貫通穴１５を有しており、コンクリート供給工程において、間配り管９は、管軸Ａを略鉛直方向に向けるとともに、管軸Ａを一端として貫通穴１５の中心Ｂを通り水平に延びる半直線ＡＢが４５°よりも大きい角度で型枠３の内壁面３ａに交差するとの条件がすべての貫通穴１５で満足される向きで打設空間５内に設置される。【選択図】図２
