CONNECTION PIPING INSTALLATION
To provide a connection piping installation that makes it easy to connect a connection tubular part to piping and prevents water from leaking between the piping and the connection tubular part.SOLUTION: A connection piping installation 1 comprises: inflow piping 10 having a tubular inflow downstream end part 12 that opens downward; and a connection tubular part 70 having a tubular connection upstream end part 71 that opens upward and is located below the inflow downstream end part 12. An inner diameter of a lower end of the inflow downstream end part 12 is smaller than that of an upper end of the connection upstream end part 71. An inner circumference of the lower end of the inflow downstream end part 12 is arranged inside an inner circumference of the upper end of the connection upstream end part 71 in a plan view. An inflow inclined surface 19 that is inclined inward toward the lower end of the inflow downstream end part 12 is formed in a portion including at least the lower end of an outer peripheral surface of the inflow downstream end part 12.SELECTED DRAWING: Figure 9
【課題】配管に接続筒状部を繋ぐことが容易であり、かつ、配管と接続筒状部との間から水が漏れ難い。【解決手段】接続配管設備１は、下方に開口した筒状の流入下流端部１２を有する流入配管１０と、上方に開口し、流入下流端部１２の下方に配置された筒状の接続上流端部７１を有する接続筒状部７０と、を備えている。流入下流端部１２の下端の内径は、接続上流端部７１の上端の内径よりも小さい。平面視において流入下流端部１２の下端の内周は、接続上流端部７１の上端の内周の内側に配置されている。流入下流端部１２の外周面の少なくとも下端を含む部分には、流入下流端部１２の下端に向かうに従って内側に向かって傾斜した流入傾斜面１９が形成されている。【選択図】図９
