To provide a rainwater drainage structure which can prevent damage of an eaves gutter of a lean-to roof with rainwater from a vertical pipe flowing rainwater from an upper roof above the lean-to roof, and easily reduces the number of downpipes guiding the rainwater to the ground.SOLUTION: A rainwater drainage structure 1 includes: an eaves gutter 10 which is mounted on an eaves of a lean-to roof and has a through hole 50a and a dropping port 72; an upstream side downpipe 5 for making rainwater flow from a roof above the lean-to roof; and a downstream side downpipe 70 having a hanging pipe 20 hanged below the through hole 50a and a branched pipe 25 for making water from the dropping port 72 flow to the lower part. The hanging pipe 20 has a branch pipe 28 which is connected with one side end of the branched pipe 25, joins rainwater from the upstream side downpipe 5 and rainwater from the branched pipe 25, and has a diameter larger than that of the upstream side downpipe 5. At least a part of the upstream side downpipe 5 is loosely fit into the through hole 50a in a relatively movable state to the through hole 50a.SELECTED DRAWING: Figure 1
【課題】下屋よりも上方の屋根からの雨水が流れる縦管からの雨水で下屋の軒樋が破損することを防止でき、地上に雨水を導く縦樋の数も少なくし易い雨水排水構造を提供すること。【解決手段】雨水排水構造１が、下屋の軒先に取り付けられ、貫通孔５０ａ及び落とし口７２を有する軒樋１０と、下屋よりも上方の屋根からの雨水を流下させる上流側竪樋５と、貫通孔５０ａの下方に垂設される垂設管２０及び落とし口７２からの水を下方に流動させる分岐管２５を有する下流側竪樋７０を備える。垂設管２０が、分岐管２５の片側端部が接続されて上流側竪樋５からの雨水と分岐管２５からの雨水とを合流させると共に上流側竪樋５よりも大径になっている枝管２８を有する。上流側竪樋５の少なくとも一部が、貫通孔５０ａに対して相対移動可能な状態で貫通孔５０ａ内に遊嵌されている。【選択図】図１
