Description

本発明は、家屋等の屋根上に樹脂系屋根材を敷設施工するための樹脂系屋根構造に関する。   The present invention relates to a resin roof structure for laying and constructing a resin roof material on a roof such as a house.

従来、家屋等の屋根上には、粘土やセメントを主原料とする窯業系瓦が屋根材として最も一般的に用いられてきたが、窯業系瓦は、高重量であるため、建物に対する負荷が大きく、設計上荷重に耐えうるものであっても地震に際しては家屋の倒壊の原因となる。   Traditionally, ceramic roof tiles mainly made of clay or cement have been used as roofing materials on roofs of houses, etc., but ceramic roof tiles are heavy and have a heavy load on the building. Even if it is large and can withstand the load, it will cause the house to collapse in the event of an earthquake.

また、振動により落下した場合には、破損して、付近の人や物に甚大な被害を及ぼすという問題もあった。   In addition, when it is dropped by vibration, there is a problem that it is damaged and causes serious damage to nearby people and things.

そこで、近年では、不飽和ポリエステル樹脂、フェノール樹脂やエポキシ樹脂等の熱硬化性樹脂に補強繊維や難燃剤、充填剤を混合して成形した軽量且つ強度の大きな樹脂系屋根材が開発されている（例えば、特許文献１参照。）。
特開２００２−２７６０８２号 Therefore, in recent years, lightweight and strong resin-based roofing materials have been developed which are formed by mixing reinforcing fibers, flame retardants, and fillers with thermosetting resins such as unsaturated polyester resins, phenol resins, and epoxy resins. (For example, refer to Patent Document 1).
JP 2002-276082 A

ところが、この樹脂系屋根材は、軽量且つ大きな強度を有する点では窯業系瓦に比べて優れている反面、防火性の点で満足すべきものであるとは言い難かった。   However, this resin roof material is superior to ceramic tiles in terms of light weight and large strength, but it is difficult to say that it is satisfactory in terms of fire resistance.

一方、防火地域又は準防火地域内の家屋等の屋根に使用される建築材料及び樹脂系屋根構造は、建築基準法における耐火試験に合格しなければならないという法規制がある。   On the other hand, there are laws and regulations that building materials and resin-based roof structures used for roofs of houses and the like in fire prevention areas or semi-fire prevention areas must pass a fire resistance test in the Building Standard Law.

本発明は、かかる課題を解決することを目的とするもので、屋根上に葺かれた樹脂系屋根構造の防火性を向上させ、建築基準法における耐火試験にも適合可能な樹脂系屋根構造を提供する。   An object of the present invention is to solve such a problem, and to improve a fire resistance of a resin roof structure sown on a roof, and to provide a resin roof structure that can be adapted to a fire resistance test in the Building Standard Law. provide.
