To provide a piping structure capable of suppressing an increase of a drainage time while shortening a syphon generation time.SOLUTION: A piping structure 20 includes first horizontal pipes 31A, 31B each connected to the downstream side of a temporary storage tank 30 provided in a drainage system via a branch connection 28 for discharging drainage water discharged from the temporary storage tank 30 in the horizontal direction, a combined joint 48 (a joint part) for joining the first horizontal pipes 31A, 31B into one, and a solid pipe 46 connected to the downstream side of the combined joint 48 for making the drainage water flow down to generate syphon force in the first horizontal pipes 31A, 31B, the branch connection 28 including pipe connection parts 29A, 29B to which the upstream ends of the first horizontal pipes 31A, 31B are connected, respectively, the pipe connection parts 29A, 29B being differently located on the branch connection 28 in a drainage inflow direction F1, with their outer peripheries partially overlapping with each other in the drainage inflow direction F1.SELECTED DRAWING: Figure 6
【課題】サイホン発生時間を短縮しつつ、排水時間の増加を抑制できる配管構造を提供する。【解決手段】配管構造２０は、排水系統に設けられる一時貯留槽３０の下流側に分岐継手２８を介して接続され、一時貯留槽３０から排出された排水を横方向に排出する第１横引き管３１Ａ，３１Ｂと、第１横引き管３１Ａ，３１Ｂを１つに合流させる合流継手４８（合流部）と、合流継手４８の下流側に接続され、排水を流下させることにより第１横引き管３１Ａ，３１Ｂにサイホン力を発生させる竪管４６と、を備え、分岐継手２８は、第１横引き管３１Ａ，３１Ｂの上流端がそれぞれ接続される配管接続部２９Ａ，２９Ｂを備えており、配管接続部２９Ａ，２９Ｂは、分岐継手２８における排水流入方向Ｆ１の位置がそれぞれ異なると共に外周の一部が互いに排水流入方向Ｆ１で重なる。【選択図】図６
