PIPING MEMBER, AND RAIN GUTTER SYSTEM
To provide a piping member and a rain gutter system which easily achieve both good design and good drainage performance.SOLUTION: A piping member attached between a first piping extending horizontally and a DL-type elbow comprises: a straight pipe portion having a first opening and a second opening; and a fin protruding from an inner peripheral surface of the straight pipe portion and extending in a circular motion about a central axis of the straight pipe portion from the first opening toward the second opening. A height of the fin in a radial direction of the straight pipe portion as viewed from a direction of the central axis of the straight pipe portion is 30% or more and 50% or less of an inner diameter of the straight pipe portion. The fin has a first end on the first opening side and a second end on the second opening side. As viewed from the direction of the central axis of the straight pipe portion, an angle between a straight line connecting the first end and the central axis of the straight pipe portion and a straight line connecting the second end and the central axis of the straight pipe portion is 140 degrees or larger and 180 degrees or smaller. The second end of the fin is in a portion of the straight pipe portion located within a receiving port of the DL-type elbow.SELECTED DRAWING: Figure 2A
【課題】デザイン性と排水性能を両立させやすい、配管部材及び雨樋システムを提供する。【解決手段】水平方向に延びる第１配管とＤＬ型エルボの間に取り付けられる配管部材は、第１開口及び第２開口を有する直管部と、直管部の内周面から突出し、第１開口から第２開口に向かって、直管部の中心軸に対して旋回して延びるフィンと、を備え、直管部の中心軸の方向から見て、直管部の径方向でのフィンの高さは、直管部の内径の３０％以上５０％以下であり、フィンは、第１開口側の第１端部と第２開口側の第２端部とを有し、直管部の中心軸の方向から見て、第１端部と直管部の中心軸とを結ぶ直線と、第２端部と直管部の中心軸とを結ぶ直線との間の角度は、１４０度以上１８０度以下であり、フィンの第２端部は、直管部においてＤＬ型エルボの受口内に位置する部分にある。【選択図】図２Ａ
