RAIN GUTTER SYSTEM AND SIPHON-INDUCING MEMBER
To provide a rain gutter system capable of improving drainage capacity while reducing the effect on appearance, and a siphon-inducing member.SOLUTION: A rain gutter system 1 constitutes a rainwater flow path 30. The rain gutter system 1 includes: a downpipe 3 connected to a dropout port 2d of an eaves gutter 2; an elbow 6 located between the eaves gutter 2 and the downpipe 3; a first connection fitting 7a for connecting the upstream end 6a of the elbow 6 to the dropout port 2d; a second connection fitting 7b for connecting the downstream end 6b of the elbow 6 to the upstream end 3a of downpipe 3; and a siphon-inducing member 5. The channel cross-sectional area of the eaves gutter 2 is 11000 mm2 or more. The inner diameter of the downpipe 3 is 67.0 mm or more. The wall thickness of the downpipe 3 is 2.2 mm or more. The siphon-inducing member 5 has a cylindrical shape and has a reduced diameter section 52 that has a smaller channel cross-sectional area than that of the second connection fitting 7b. The siphon-inducing member 5 is located directly below the second connection fitting 7b in the channel 30.SELECTED DRAWING: Figure 1
【課題】外観への影響を低減しながら排水能力を向上できる、雨樋システム及びサイフォン誘発部材を提供する。【解決手段】雨樋システム１は、雨水の流路３０を構成する。雨樋システム１は、軒樋２の落とし口２ｄに接続される竪樋３と、軒樋２と竪樋３との間にある呼び樋６と、呼び樋６の上流側の端６ａを落とし口２ｄに接続する第１接続継手７ａと、呼び樋６の下流側の端６ｂを竪樋３の上流側の端３ａに接続する第２接続継手７ｂと、サイフォン誘発部材５と、を備える。軒樋２の流路断面積は、１１０００ｍｍ２以上である。竪樋３の内径は、６７．０ｍｍ以上である。竪樋３の肉厚は、２．２ｍｍ以上である。サイフォン誘発部材５は、筒状であり、第２接続継手７ｂの流路断面積より小さい流路断面積を有する縮径部５２を有する。サイフォン誘発部材５は、流路３０において第２接続継手７ｂの直下にある。【選択図】図１
