PIT MEMBER AND RAINWATER DRAINAGE SYSTEM
To improve discharge efficiency of rainwater in a pit member, and to widen a range in which an outer diameter of a connection part of a drain or a down pipe connected to the pit member can be selected.SOLUTION: In a pit member 10, a drain pipe for draining rainwater penetrates an outer wall of a building, an end of the drain pipe protrudes from the outer surface of the outer wall, the pit member 10 is connected to the upper end of a downpipe arranged along the outer wall, and the drain pipe is connected to the pit member 10 to constitute a rainwater drainage system. The pit member 10 is formed in a box shape with a bottom plate that can be formed with a hole for connecting a drain or downpipe, which can be selected arbitrarily from a plurality of holes of different sizes, the outer shape viewed from the lower side of a lower end outer peripheral edge 11b is smaller than the outer shape viewed from the upper side of an upper end outer peripheral edge 11a, and the outer shape viewed from the front surface side of a front surface 15 on the opposite side to the outer wall is smaller than the outer shape viewed from the back surface side of a back surface 18 on the outer wall side.SELECTED DRAWING: Figure 2
【課題】桝部材において、雨水の排出効率を向上させ、かつ、桝部材に接続するドレンまたは竪樋の接続部の外径を選択できる範囲を広げることである。【解決手段】桝部材１０は、雨水を排水する排水管が建物の外壁に貫通しており、外壁の外面から排水管の端部が突出し、外壁に沿って配置された竪樋の上端に桝部材１０が接続され、桝部材１０に排水管が接続された雨水排水システムを構成するための桝部材１０である。桝部材１０は、ドレンまたは竪樋を接続するための孔であって、大きさの異なる複数の孔から任意に選択可能な孔を形成可能な底板部を有する箱形状に形成され、上端外周縁１１ａの上方から見た外形より下端外周縁１１ｂの下方から見た外形が小さく、かつ、外壁側の背面１８の背面側から見た外形より外壁と反対側の前面１５の前面側から見た外形が小さくなっている。【選択図】図２
