Description

【０００１】
【発明の属する技術分野】
本発明は、アーチ型断熱屋根の構造に関し、詳しくは、表裏の金属外皮間に断熱材を充填した断熱屋根材を緩やかに弧状に良好に湾曲するとともに湾曲させるための構成によって外観が低下されることを防止する技術に係るものである。
【０００２】
【従来の技術】
従来、図３に示すように、表裏の金属外皮１，２間に断熱材３を充填した断熱屋根材４を緩やかに弧状に湾曲して施工するアーチ型断熱屋根の構造においては、断熱屋根材４を支持する母屋５…の位置において断熱屋根材４の表の金属外皮１にベコツキが生じたり、裏の金属外皮２に座屈が生じることがあった。特に、断熱屋根材４は母屋５の長さ方向に間隔を隔てて角型山部８を複数本形成する断熱屋根材４においては顕著なものとなる。
【０００３】
【発明が解決しようとする課題】
本発明はこのような問題に鑑みてなされたものであり、表裏の金属外皮間に断熱材を充填した断熱屋根材を緩やかに弧状に良好に湾曲するとともに湾曲させるための構成によって外観が低下されることを防止することができるアーチ状型断熱屋根の構造を提供することを課題とするものである。
【０００４】
【課題を解決するための手段】
請求項１においては、表裏の金属外皮１，２間に断熱材３を充填した断熱屋根材４を緩やかに弧状に湾曲して施工するアーチ型断熱屋根の構造であって、断熱屋根材４を支持する母屋５…の位置において断熱屋根材４のアーチ状面の接線方向に対して略直交する方向に裏の金属外皮２及び断熱材３の一部に切除溝６を形成し、切除溝６から離れた位置において貫通ボルト７にて断熱屋根材４を母屋５に固定するとともに切除溝６を母屋５上に位置させてあることを特徴とするものである。このような構成によれば、裏の金属外皮２と一部の断熱材３とに形成した切除溝６によって断熱屋根材４を緩やかに曲げることができ、表裏の金属外皮１，２にベコツキや座屈が生じることがなく、しかも、貫通ボルト７によって切除溝６を外して断熱屋根材４を母屋５に固定することから、断熱屋根材４を母屋５に強固に固定することができながら、切除溝６は母屋５の位置にあるから、切除溝６が外部に現われることがなく、外観を低下することがない。
【０００５】
請求項２においては、切除溝６は貫通ボルト７よりもアーチ形状における上位置に配されてあることを特徴とするものである。このような構成によれば、貫通ボルト７は切除溝６のアーチ形状における下位置あることから、貫通ボルト７による断熱屋根材４の固定強度を高めることができる。
【０００６】
ところで、断熱屋根材４は母屋５の長さ方向に間隔を隔てて角型山部８を複数本形成してあることも好ましいものである。又、切除溝６の深さＬは十数ミリで幅Ｗは数ミリであることも好ましいものである。
【０００７】
【発明の実施の形態】
以下、本発明の実施の形態を説明する。図１（ａ）は概略側面図、同図（ｂ）は施工後の拡大断面図、同図（ｃ）は施工前の断面図、図２は断熱屋根材の斜視図である。
【０００８】
塗装鋼鈑にて形成している表裏の金属外皮１，２間に硬質ウレタンフォームやイソシアヌレートフォームの断熱材３を充填して断熱屋根材４を形成してあって、断熱屋根材４には母屋５の長さ方向に間隔を隔てて角型山部８を複数本形成している。
【０００９】
このような断熱屋根材４をアーチ型に曲げて屋根を構成するのであり、アーチ型に曲げる曲率半径Ｒは、限界半径が約３０ｍであり、施工はこれ以下にすることが好ましい。
【００１０】
断熱屋根材４の厚さＴは２５ｍｍ、３５ｍｍもしくは４５ｍｍのものがあり、角型山部８の高さＨは３８ｍｍであるが、他の寸法のものでもよい。断熱屋根材４の長さＭは２０ｍ程度までであり、軒先から棟部に至る長さのものである。
【００１１】
図１に示すように、断熱屋根材４を支持する母屋５…の位置において、断熱屋根材４のアーチ状面の接線方向に対して略直交する方向に裏の金属外皮２及び断熱材３の一部に切除溝６を全幅に形成している。切除溝６の深さＬは１２ｍｍで幅Ｗは３ｍｍであるが、この近傍の数値であればよい。要するに、切除溝６の深さＬは十数ミリで幅Ｗは数ミリであればよい。
【００１２】
しかして、図１（ｂ）に示すように、切除溝６から離れた位置において貫通ボルト７にて断熱屋根材４を母屋５に固定するとともに切除溝６をアーチ形状の上位置に配するのである。ところで、アーチ形状の頂点においては、切除溝６は貫通ボルト７の左右のいずれにずらせていてもよいものである。
【００１３】
このような構成によれば、裏の金属外皮２と一部の断熱材３とに形成した深さＬが約１２ｍｍで幅Ｗが約３ｍｍの切除溝６によって断熱屋根材４を緩やかに曲げることができるのであり、表裏の金属外皮１，２にベコツキや座屈が生じることがないのである。しかも、貫通ボルト７によって切除溝６を外して断熱屋根材４を母屋５に固定することから、断熱屋根材４を母屋５に強固に固定することができながら、切除溝６は母屋５の位置にあるから、切除溝６が下面側に現われることがなく、外観を低下することがないものである。
【００１４】
尚、実施の形態においては、断熱屋根材４には角型山部８を形成したが、角型山部８がないフラットな断熱屋根材４であってよいものである。
【００１５】
【発明の効果】
請求項１においては、表裏の金属外皮間に断熱材を充填した断熱屋根材を緩やかに弧状に湾曲して施工するアーチ型断熱屋根の構造であって、断熱屋根材を支持する母屋の位置において断熱屋根材のアーチ状面の接線方向に対して略直交する方向に裏の金属外皮及び断熱材の一部に切除溝を形成し、切除溝から離れた位置において貫通ボルトにて断熱屋根材を母屋に固定するとともに切除溝を母屋上に位置させてあるから、裏の金属外皮と一部の断熱材とに形成した切除溝によって断熱屋根材を緩やかに曲げることができ、表裏の金属外皮にベコツキや座屈が生じることがなく、しかも、貫通ボルトによって切除溝を外して断熱屋根材を母屋に固定することから、断熱屋根材を母屋に強固に固定することができながら、切除溝は母屋の位置にあるから、切除溝を外部に現われることがなく、外観を低下することがないという利点がある。
【００１６】
請求項２においては、切除溝は貫通ボルトよりもアーチ形状における上位置に配されてあるから、請求項１の効果に加えて、貫通ボルトは切除溝の下位置あることから、貫通ボルトによる断熱屋根材の固定強度を高めることができるという利点がある。
