BEND JOINT AND DRAIN PIPING SYSTEM WITH BEND JOINT
To provide a structure of a drain assembly joint which can be verified inside of the pipe easily when the defect occurs in the pipe.SOLUTION: The bend joint of the invention is a bend joint constituted in polyolefin resin and applied for a drain piping having a siphon generating part, comprises a first straight pipe part, a second straight pipe part and a bend pipe part for coupling the first straight pipe part and the second straight pipe part and a third straight pipe part is formed at a midway part of the bend pipe part and both of a cross angle of a shaft line of the first straight pipe part and a shaft line of the third straight pipe part, and a cross angle of a shaft line of the second straight pipe part and a shaft line of the third straight pipe part are equal to or smaller than 45 degrees.SELECTED DRAWING: Figure 1
【課題】本発明は、管内に異常が生じた場合に管内を簡単に確認できる排水集合継手の構造の提供を目的とする。【解決手段】本発明のベンド継手は、ポリオレフィン系樹脂からなり、サイフォン発生部を有する排水配管に適用されるベンド継手であって、第１直管部と、第２直管部と、前記第１直管部および前記第２直管部を連結するベンド管部を備え、前記ベンド管部の途中部分に第３直管部が形成され、前記第１直管部の軸線と前記第３直管部の軸線の交差角度と、前記第２直管部の軸線と前記第３直管部の軸線の交差角度が、いずれも４５゜以下であることを特徴とする。【選択図】図１
