DRAINAGE MEMBER FOR EAVES GUTTER AND RAIN GUTTER STRUCTURE
To improve workability by improving the re-screwing work when constructing drainage members for eaves gutters.SOLUTION: A drainage member for draining rainwater from an opening on a bottom surface of an eaves gutter to a gutter has a flange 200 that abuts on the periphery of the opening from below and a drain 300 that is screwed into the flange 200 through the opening. The flange 200 has a cylindrical female cylinder, and the female cylinder has a female screw portion 230 provided inside. The drain has a male cylinder that is provided on the lower side and has an outer diameter smaller than the inner diameter of the female cylinder. The male cylinder has a male screw portion 330 provided on the outer side of the upper portion and screwed into the female screw portion 230, and a screwless portion 340 provided on the outer side of the lower portion. An outer diameter φ3 of the screwless portion 340 is larger than an outer diameter φ2 of a male screw valley portion 332 of the male screw portion 330 and smaller than an inner diameter φ1 of a female screw thread portion 231 of the female screw portion 230.SELECTED DRAWING: Figure 5
【課題】軒樋用排水部材を施工する際の螺合作業のやり直しが改善され、作業性の向上を目的とする。【解決手段】軒樋の底面の開口から竪樋へ雨水を排水するための排水部材は、下方から開口の周囲に当接するフランジ２００と、フランジ２００に開口を介して螺合するドレン３００と、を有する。フランジ２００は円筒状の雌円筒を有して、雌円筒は、内側に設けられた雌ネジ部２３０を有する。ドレンは、下側に設けられ雌円筒の内径より小さい外径の円筒状である雄円筒を有して、雄円筒は、上部の外側に設けられ雌ネジ部２３０に螺合する雄ネジ部３３０と、下部の外側に設けられたネジ無し部３４０と、を有する。ネジ無し部３４０の外径φ３は、雄ネジ部３３０の雄ネジ谷部３３２の外径φ２よりも大きく、雌ネジ部２３０の雌ネジ山部２３１の内径φ１よりも小さいことを特徴とする。【選択図】図５
