DRAIN DEVICE AND ROOF DRAIN SYSTEM
To provide a drain device and a roof drain system capable of securing sufficient drain property without enlarging a pipe diameter while suppressing cost.SOLUTION: A drain device 1 is installed on a face where water stays such as a building structure roof, and has a function of making the staying water flow through an opening on the face into a drain pipe below. A strainer member 10 is provided in the drain device 1. The strainer member 10 comprises: an outside fin 13 disposed to face a water flow revolving around the opening of the face and changing a direction of the water flow to a direction moving near the center of the opening; and an outside fin 14 changing a direction of the water flow going from an outside to an inside of the strainer member 10 to a direction moving near a shaft line of the opening.SELECTED DRAWING: Figure 7
【課題】コストを抑えつつ、管径を拡大しなくても十分な排水性能を確保できるドレン装置及びルーフドレンシステムを提供する。【解決手段】ドレン装置１は、建造物の屋根等の水が溜まる面に設置され、溜まった水を前記面の開口を通して下方の排水管に流す機能を有する。このドレン装置１に、ストレーナ部材１０が設けられており、前記ストレーナ部材１０は、前記面の開口の周囲で旋回する水流に対向して配置され、前記水流の向きを前記開口の中心に近づく方向に変更する外側フィン１３と、前記ストレーナ部材１０の外側から内側に向かう水流の向きを、前記開口の軸線に近づく方向に変更する内側フィン１４とを備える。【選択図】図７
