RAINWATER PIPE
To provide a rainwater pipe capable of suppressing hammering sounds and flowing water sounds caused by rainwater flowing inside the rainwater pipe.SOLUTION: A rainwater pipe 10 is tubular and comprises an inlet opening part 12, an outlet opening part 13 spaced apart from the inlet opening part 12 in a -Z direction (longitudinal direction), and an intermediate part 14 connecting between the inlet opening part 12 and the outlet opening part 13. The intermediate part 14 has a circular pipe shape with a central axis 41 curved in a spiral manner. An inner wall of the intermediate part 14 may be a smooth curved surface. The intermediate part 14 may impart a double spiral rotation to rainwater falling and flowing therethrough.SELECTED DRAWING: Figure 4
【課題】雨水管のなかを流れる雨水による打ち付け音及び流水音を抑制する。【解決手段】雨水管１０は、管状であり、入口開口部１２と、入口開口部１２から－Ｚ方向（長手方向）に離間した出口開口部１３と、入口開口部１２と出口開口部１３との間を接続する中間部１４とを有する。中間部１４は、中心軸４１が螺旋状に湾曲した円管形状である。中間部１４の内壁は、滑らかな曲面であってもよい。中間部１４は、そのなかを流れ落ちる雨水に二重の螺旋状回転を与えてもよい。【選択図】図４
