Description

本発明は、勾配を有した屋根面の頂部付近に配置され、所定の水密性能と所定の換気性能とを備えた換気部材ユニット及びこの換気部材ユニットを用いた棟換気装置の施工方法に関する。 The present invention relates to a ventilation member unit that is arranged near the top of a sloped roof surface and has a predetermined watertight performance and a predetermined ventilation performance, and a method of constructing a ridge ventilation system using this ventilation member unit.

現在の屋根用換気装置は、陸棟、片棟、又は下屋の雨押え部などの屋根部位ごとに設計している。
例えば、特許文献１は陸棟用の換気装置であり、特許文献２は片棟用の換気装置であり、特許文献３は下屋の雨押え部における換気装置である。 Current roof ventilation systems are designed for each part of the roof, such as a land ridge, a single ridge, or a rain flashing part of a lower building.
For example, Patent Document 1 is a ventilation device for a land building, Patent Document 2 is a ventilation device for a single building, and Patent Document 3 is a ventilation device for a rain flashing part of a shed.

このように、屋根用換気装置は、屋根部位ごとに設計するが、屋根材の種類や屋根勾配などの条件に応じて設計し、更には、鋼板の色調に応じて提供する必要があり、これらの組み合わせが発生するために、多品種を生産する必要があり、これら多品種を在庫として保管する必要もある。また、屋根用換気装置は、製品形状的に幅と厚みがあるためスタッキング性が悪く、物流コストも掛かるという課題もある。
特許文献１から特許文献３に記載の換気装置は、いずれも勾配を有した屋根面の頂部付近に配置され、所定の水密性能と所定の換気性能とを備えた換気装置として、軒先側に配置される前面部に前面開口を形成し、屋根頂部側に配置される背面部に背面開口を形成し、前面部から所定間隔離れた位置に配置して前面開口に対向させた風雨誘導板を有するものである。
しかし、特許文献１から特許文献３に記載の換気装置は、換気装置として要求される水密性能と換気性能とを、天面カバー（特許文献１においては棟カバー、特許文献２においては上板、特許文献３においては長尺状部材が相当）を必須部材として設計されている。
すなわち、天面カバーを必須部材として、水密性能と換気性能とを設計するために、屋根部位ごとに設計しなければならず、また屋根材の種類や屋根勾配などの条件に応じて設計し、更には、鋼板の色調に応じて提供する必要が生じてしまう。 In this way, roof ventilation systems are designed for each roof area, but they also need to be designed according to conditions such as the type of roofing material and roof slope, and furthermore, they need to be provided according to the color tone of the steel plate. In order for this combination to occur, it is necessary to produce a wide variety of products, and it is also necessary to store these products in inventory. In addition, roof ventilation devices have problems in that they have poor stacking properties due to their product shape, which is wide and thick, resulting in high logistics costs.
The ventilation devices described in Patent Documents 1 to 3 are all placed near the top of a sloped roof surface, and are placed on the eaves side as ventilation devices with predetermined watertight performance and predetermined ventilation performance. A front opening is formed in the front part located on the roof top side, a rear opening is formed in the rear part located on the top side of the roof, and a wind and rain guiding plate is arranged at a predetermined distance from the front part and facing the front opening. It is something.
However, the ventilation devices described in Patent Documents 1 to 3 do not provide the watertight performance and ventilation performance required for ventilation devices by using a top cover (a ridge cover in Patent Document 1, a top plate in Patent Document 2), In Patent Document 3, a long member (elongated member) is designed as an essential member.
In other words, in order to design watertightness and ventilation performance with the top cover as an essential component, each part of the roof must be designed according to conditions such as the type of roofing material and roof slope. Furthermore, it becomes necessary to provide the steel sheet according to its color tone.

そこで本発明は、天面カバーの構造によることなく、所定の水密性能と所定の換気性能とを備える換気部材ユニットを提供することを目的とする。
また本発明は、屋根構造に対応する天面カバーを用いるだけで、種々の屋根材に対しても換気部材ユニットを適用することができる棟換気装置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 ventilation member unit that has a predetermined watertight performance and a predetermined ventilation performance regardless of the structure of the top cover.
Another object of the present invention is to provide a method for constructing a ridge ventilation system that allows the ventilation member unit to be applied to various roof materials by simply using a top cover that corresponds to the roof structure.
