Description
本願発明は、建物の勾配屋根の表面に敷設される屋根仕上げ材とこれによるスレート屋根の改修方法に関し、詳しくは形状に特徴を有し、施工性に優れる屋根仕上げ材とこれによる既存の平板スレート屋根の改修方法に関するものである。 The present invention relates to a roof finishing material laid on the surface of a pitched roof of a building and a method for repairing a slate roof using the roof finishing material. More specifically, a roof finishing material having a characteristic shape and excellent in workability and an existing flat plate slate using the same It concerns the method of roof renovation.
屋根仕上げ材のシングル（Roofing shingles）は、瓦屋根材や金属屋根材より軽量であり、また、施工現場での加工性が良いことから広く使用されている。特にガラス繊維基材にアスファルトを含浸塗覆し表面に着色砂を圧着させたアスファルトシングル（Asphalt shingles）やガラス繊維基材に無機充填材と樹脂材との混合層を形成した不燃シングル（Incombustible shingles）は、防水性、耐久性に優れることから米国をはじめ日本や他の多くの国々で、屋根仕上げ材として用いられている。 Single roofing materials (Roofing shingles) are widely used because they are lighter in weight than tile roof materials and metal roof materials and have good workability at construction sites. In particular, asphalt singles (Asphalt shingles) in which asphalt is impregnated and coated on the glass fiber substrate and colored sand is pressed onto the surface, and noncombustible singles (Incombustible shingles) in which a mixed layer of inorganic filler and resin material is formed on the glass fiber substrate. Because of its excellent waterproofness and durability, is used as a roof finishing material in the United States, Japan, and many other countries.
シングルを取り付け施工する方法としては、木質系下地の場合、通常釘打ちと接着剤を併用する。既存の平板スレート屋根の改修工事において、既存屋根へのかぶせ工法においても同様の方法が採られる。 As a method of attaching and installing a single, in the case of a wooden base, usually nailing and an adhesive are used together. The same method will be applied to the existing flat roof slate roof repair work.
近年、施工者の負担軽減が課題として挙げられており、シングルの施工性を向上させるために様々な考案がなされている。例えば、特許文献１には粘着層と剥離シート材を有することを特徴とするアスファルトシングルが開示されている。また、特許文献２には、釘打ちを効果的に行うための釘打ち領域を備えたアスファルトシングルが開示されている。 In recent years, reducing the burden on the builder has been cited as an issue, and various ideas have been made to improve the workability of a single. For example, Patent Document 1 discloses an asphalt single having an adhesive layer and a release sheet material. Further, Patent Document 2 discloses an asphalt single having a nailing area for effectively performing nailing.
また、シングル表面を覆う着色砂は、経年で剥落するため、乾性油で砂を処理し撥水性を付与し、剥落性を改善する考案が特許文献３に開示されている。
さらに、シングル葺きによる屋根は、年を経るに従い表面に藻の発生により、暗緑色に変色現象が生じることがあるため、防藻性を付与する考案が特許文献４に開示されている。
Further, since the colored sand covering the surface of the single piece comes off with the passage of time, Patent Document 3 discloses a device for treating the sand with a drying oil to impart water repellency to improve the exfoliation property.
Furthermore, since the roof of a single thatch may change its color to dark green due to the generation of algae on the surface as the years pass, Patent Document 4 discloses a device for imparting anti-algae property.
特許文献１に開示される粘着層や、特許文献２に開示される釘打ち領域は、施工性向上に寄与するものの、施工者の負担を軽減し、施工性向上を図るためには、さらなる改善が求められている。また、特許文献３に開示される方法では、砂の剥落を完全に防止することはできず、経年の風雨で砂の剥落が生じる虞があった。さらに、特許文献４に開示される方法ではトリアジン系の防藻剤を添加する必要があった。 Although the adhesive layer disclosed in Patent Document 1 and the nailing region disclosed in Patent Document 2 contribute to the improvement of the workability, further improvement is required in order to reduce the burden on the operator and improve the workability. Is required. Further, the method disclosed in Patent Document 3 cannot completely prevent the sand from coming off, and there is a possibility that the sand may come off due to wind and rain over the years. Furthermore, in the method disclosed in Patent Document 4, it was necessary to add a triazine-based algae preventative agent.
一方、戸建て住宅用の屋根材としては、工期が短く意匠性も良いことから、平板スレートが採用されてきたが、経年劣化により退色、漏水が発生する場合があり、既存のスレート屋根の改修手段が求められている。その一つとして、既存のスレート屋根にアスファルトシングルや不燃シングルをかぶせ施工する方法があるが、既存のシングルを用いた場合、葺き足（働き）の違いから、外観上の不具合、凹凸部が生じるという問題があった。 On the other hand, as a roofing material for detached houses, flat slate has been adopted because it has a short construction period and good design, but discoloration and water leakage may occur due to deterioration over time, so existing slate roof repairing means Is required. As one of them, there is a method of covering the existing slate roof with asphalt single or non-combustible single, but when using the existing single, there are defects in appearance and uneven parts due to the difference in thatched feet (work). There was a problem.
そこで、本発明は、既存のシングルの形状を大型化し、施工単位面積当たりの必要部材数および釘打ち数を減らすこと、およびシングル表面に高分子量ポリエチレン粒子を担持した樹脂層を設けることで、位置決めに掛かる時間を短縮することで施工性を向上させ、且つ砂の剥落が無く防藻性を有する屋根材を提供し、さらに既存のスレート屋根（コロニアル屋根）の改修時に、かぶせ工法を採用した際に生じる凹凸の外観不良が生じない、施工方法を提供する。
改修以外に本発明品を用いるとき、すなわち新築時に使用する際は、さらに施工単位面積当たりの必要部数を減らすことが可能である。具体的には、スレート屋根の改修に当たっては、葺き足１８２ｍｍで５．５枚／ｍ２であるのに対し、例えば、短辺４８５ｍｍでは葺き足を２１７ｍｍまで拡大し、４．６枚／ｍ２まで必要部数を減らすことが出来る。さらに短辺５４０ｍｍとすると葺き足は２５４ｍｍまで拡大することが出来る為に必要部数は４．１枚／ｍ２まで減じることが可能である。
Therefore, the present invention, by enlarging the shape of the existing single, reducing the number of necessary members and the number of nailing per construction unit area, and by providing a resin layer carrying high molecular weight polyethylene particles on the surface of the single, positioning By improving the workability by shortening the time required for the construction, and providing a roof material with algae-proof property without the removal of sand, and when adopting the cover method when renovating the existing slate roof (colonial roof) Provided is a construction method which does not cause a defective appearance of unevenness caused by the above.
When the product of the present invention is used for other than the refurbishment, that is, when it is used for new construction, it is possible to further reduce the required number of copies per construction unit area. Specifically, when repairing a slate roof, the number of roofing legs 182 mm is 5.5 sheets/m 2 , whereas, for example, when the short side is 485 mm, the number of roofing legs is expanded to 217 mm and 4.6 sheets/m 2 You can reduce the required number of copies. Further, if the short side is 540 mm, the thatched leg can be expanded to 254 mm, and therefore the required number of copies can be reduced to 4.1 sheets/m 2 .
上記課題を解決するために、本件第一発明は、ガラス繊維基材にアスファルトを含浸塗覆し表面に鉱物砂を撒布圧着させたアスファルトシングルおよびガラス繊維基材の両面に無機質充填材と樹脂材との混合層を形成し表面に鉱物砂を撒布圧着させた不燃シングルからなる群から選択される屋根仕上げ材であって、屋根仕上げ材が、平面視で、上辺、下辺、左辺および右辺を有する略長方形の形状を有し、上辺および下辺の長さが９００〜１２００ｍｍであり、左辺および右辺の長さが４２０〜５４０ｍｍであることを特徴とする。
