Description

本発明は、建造物の屋根面に配置される屋根面換気ユニット及び屋根面換気ユニットの施工方法に関する。 The present invention relates to a roof surface ventilation unit and a method of constructing a roof surface ventilation unit arranged on the roof surface of a building.

特許文献１は、屋根の野地板に設けた開口部のまわりに換気路本体等を設置し、換気路本体の外周部を取り囲む捨水切板部材と、換気路本体の上部を覆う上部カバーとを、板金性の一体物とすることで、部品点数の少数化が図られ、施工が容易になり、且つ低コスト化が可能になる換気ユニットを提案している。 In Patent Document 1, a ventilation path main body or the like is installed around an opening provided in a field plate of a roof, and a drainage plate member surrounding the outer peripheral portion of the ventilation path main body and an upper cover covering the upper part of the ventilation path main body are provided. We are proposing a ventilation unit that can reduce the number of parts, facilitate construction, and reduce costs by making it a sheet metal integrated product.

特開２０００−２５７２２８号公報Japanese Unexamined Patent Publication No. 2000-257228

しかし、特許文献１による上部カバーは、捨水切板部材の軒側端部から屈曲して軒側に向けて野地板から徐々に離間するように傾斜した傾斜部分と、この傾斜部分の軒側端部から屈曲して野地板と平行に軒側に延設された平坦部分とからなり、傾斜部分に捨水切枠部材を配置している。
従って、特許文献１では、捨水切枠部材の上部空間が傾斜部分によって狭くなっているため換気性能を低下させてしまう。 However, the upper cover according to Patent Document 1 has an inclined portion that is bent from the eaves side end portion of the drainage plate member and inclined so as to gradually separate from the field plate toward the eaves side, and an eaves side end of this inclined portion. It consists of a flat part that bends from the part and extends parallel to the field board on the eaves side, and a drainage frame member is arranged on the inclined part.
Therefore, in Patent Document 1, since the upper space of the drainage frame member is narrowed by the inclined portion, the ventilation performance is deteriorated.

そこで本発明は、捨水切板部材と上部カバーとを板金性の一体物とすることなく止水性を高めるとともに野地開口部の上方空間を確保できる屋根面換気ユニットを提供することを目的とする。
また本発明は、捨水切板部材と上部カバーとを板金性の一体物とすることなく止水性を高めるとともに屋根面換気ユニットと屋根面との一体感が高まり美観に優れる屋根面換気ユニットの施工方法を提供することを目的とする。 Therefore, an object of the present invention is to provide a roof surface ventilation unit capable of improving water stopping and securing a space above the field opening without making the drainage plate member and the upper cover a sheet metal integral body.
Further, in the present invention, the construction of the roof surface ventilation unit, which is excellent in aesthetics, enhances the water stopping property without making the drainage cutting plate member and the upper cover into a sheet metal integral body, and enhances the sense of unity between the roof surface ventilation unit and the roof surface. The purpose is to provide a method.
