To provide a rainwater drainage structure capable of efficiently draining rainwater from a roof above a lean-to roof and rainwater from an eaves gutter of the lean-to roof, and improving workability and design of construction.SOLUTION: A rainwater drainage structure includes an eaves gutter installed on a building with a lean-to roof and attached to the eaves of the lean-to roof, an upper leader that drains rainwater from the roof above the lean-to roof, and a drain 40 attached to the through hole of the eaves gutter and drains rainwater from the eaves gutter downward, inducing a siphon effect. The upper drain member of the drain includes an upper flange attached to the top surface of the bottom plate of the eaves gutter, an upper cylindrical portion that passes through the through hole, a wing portion installed at a plurality of positions in the circumferential direction on the upper surface of the upper flange, and an upper leader connection portion that is supported by the wing portion and connects the upper leader. The lower drain member of the drain has a lower cylindrical portion that is provided below the lower flange and into which the upper cylindrical portion is inserted. The lower end of the upper leader connection position is located higher than the top surface of the upper flange.SELECTED DRAWING: Figure 5
【課題】下屋よりも上方の屋根からの雨水と下屋の軒樋からの雨水とを効率よく排水でき、かつ、施工の作業性及び意匠性を向上できる雨水排水構造を提供する。【解決手段】雨水排水構造は、下屋を備える建物に設置され、下屋の軒先に取り付けられた軒樋と、下屋よりも上方の屋根からの雨水を流下させる上側竪樋と、軒樋の貫通孔に取り付けられ、軒樋の雨水を下方に排出し、サイフォン現象を誘発するドレン４０とを含む。ドレンの上側ドレン部材は、軒樋の底板の上面に取付けられる上フランジと、貫通孔を貫通する上側筒部と、上フランジの上面の周方向複数位置に立設される羽根部と、羽根部に支持され、上側竪樋を接続する上側竪樋接続部とを有する。ドレンの下側ドレン部材は、下フランジの下側に設けられ、内側に上側筒部が挿入される下側筒部を有する。上側竪樋接続部の下端は、上フランジの上面より高い位置にある。【選択図】図５
