RAINWATER DRAINAGE DEVICE
To provide a rainwater drainage device for smoothly draining rainwater on a roof of an existing part of a building with favorable maintainability and achievable lower cost.SOLUTION: A rainwater drainage device consists of a communication gutter, a receiving gutter and a box gutter. The communication gutter communicates with a drainage port on a roof of an existing part, and its drainage port is located above a roof of an extended part. The receiving gutter is located on a portion of the roof of the extended part overlapping with the drainage port of the communication gutter in planar view, and its top surface is open. The box gutter is located on the roof of the extended part, and its top surface is open. The box gutter has a linear part connected to the receiving gutter and extending downward almost linearly from the connection portion with the receiving gutter, and an expanded width part which is wider in a first direction crossing the roof inclination direction than the linear part and has multiple drainage ports in different locations in the first direction.SELECTED DRAWING: Figure 3
【課題】建築物の既設部分の屋根上に降下した雨水を円滑に排水でき、メンテナンス性が高く、コストが低減できる雨水排水装置を提供する。【解決手段】雨水排水装置は、連通樋と受樋と箱樋とを備える。連通樋は、既設部分の屋根に設けられた排水口に連通する樋であり、増築部分の屋根の上方の位置に排水口が形成されている。受樋は、増築部分の屋根上における、上面視で連通樋の排水口に重なる位置に設置され、上面が開放された樋である。箱樋は、増築部分の屋根上に設置され、上面が開放された樋である。箱樋は、受樋に接続され、受樋との接続箇所から水下側に向かって略直線状に延びる直線状部と、直線状部の水下側の端部に接続され、直線状部と比較して屋根勾配方向に直交する第１の方向の幅が広く、第１の方向における位置が互いに異なる複数の排水口が形成された拡幅部とを有する。【選択図】図３
