SIPHON DRAIN SYSTEM
To provide an elbow for flowing rain water down smoothly.SOLUTION: An elbow 114 is installed at a downstream side of a siphon rain gutter system having an eaves gutter, a cylindrical part penetrating a water collection port formed on a bottom surface of the eaves gutter, and a siphone generation part for generating a siphon phenomenon. The elbow comprises a bent pipe part, and receptacles provided at both ends of the bent pipe part, wherein a radius of curvature of an inner wall surface of an inner peripheral side is greater than 64 mm and smaller than 100 mm in the bent pipe part seen in a cross section in a plane including a tube axis of the bent pipe part.SELECTED DRAWING: Figure 4
【課題】雨水を円滑に流下させるエルボを提供する。【解決手段】本発明に係るエルボ１１４は、軒樋と、前記軒樋の底面に形成された集水口を貫通する筒状部を備え、且つサイフォン現象を発生させるためのサイフォン発生部と、を備えたサイフォン雨樋システムの下流側に設置されるエルボであって、曲管部と、前記曲管部の両端に設けられた受け口と、を備え、前記曲管部の管軸を含む平面における断面で見たときの前記曲管部において、内周側の内壁面の曲率半径が６４ｍｍよりも大きく、かつ、１００ｍｍよりも小さい。【選択図】図４
