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
