【発明の属する技術分野】
本発明は、屋根材として今までにない重厚感、施工性を有し、かつ防水機能、断熱機能、結露防止機能、雪止め機能、等を形成した屋根材に係るものである。
【0002】
【従来の技術】
一般に、金属製板材をロール成形、プレス成形等して加工した屋根材は数多く上市され、その形状は、所謂引っ掛け構造であった。(例えば、特許文献1、2参照)。また、従来、屋根は耐振性、強度、施工性、重量の関係で、金属製屋根材が注目を浴びてきた。しかしながら、金属製屋根材は意匠性に乏しく、また、凹凸が大きい瓦屋根のような屋根材に比べて、屋根に積もった雪が簡単に軒下に落下する危険性があり、屋根材本体に雪止め機能を付加した屋根材を使用した屋根構造が開発されている。(例えば、特許文献3、4参照)。

【発明が解決しようとする課題】
しかしながら、特許文献1、2は引っ掛け構造であるために、勾配が急な屋根に使用した際に、連結した上段の屋根材が自重で落ちてくるので、上段の屋根材の固定部を固定具(釘)で固定するまで、屋根材が落ちないように手で押さえている必要があり、施工が大変であった。しかしながら、特許文献3、4の構造では、下段の屋根材に上段の屋根材を施工する際に、上段の屋根材に折り曲げ加工を施して屋根材を施工するものであった。このために、▲1▼施工性が悪い、▲2▼施工が難しい、▲3▼施工を確実にしないと雨漏れの原因になる、▲4▼屋根材表面に傷が付く、等の欠点があった。
【0005】
【課題を解決するための手段】
本発明はこのような欠点を解決するために、幅方向の側端縁に落とし込み構造の雄雌連結構造を形成すると共に、化粧面の水上側の先端には上方に突出した係合兼防水片と、係合兼防水片の先端を水下側へ突出した防水片と、係合兼防水片の根本を水下側に突出した上面と、上面の先端を下方に垂下し先端を水上側に突出した固定片を形成し、化粧面の水下側の先端には上方に突出した垂直片と、下方に突出した段差化粧面と、垂直片の先端を水上側に突出した突出片と、化粧面の水下側先端近傍を下方に突出した最奥片と、最奥片の先端を水下側に突出した差込片を形成した屋根材を提供するものである。
【0006】

【0007】
下地αは、新築の際は図2(a)、(b)に示すように垂木1、野地板2、防水シート3(一点鎖線で示す)から構成した木造下地を示したものである。すなわち、垂木1上に野地板2を敷設し、野地板2上に防水シート3を配設した一般的な構造の下地αである。また、下地αとしてH形鋼、I形鋼、ミゾ形鋼、軽量ミゾ形鋼、リップ溝形鋼、等辺山形鋼、不等辺山形鋼、角形鋼(角パイプ)、円形鋼(円形パイプ)、等を使用した鉄骨下地でも良いものである。勿論、既存の屋根をそのまま改修する屋根の際には、これら下地α上に新生瓦や瓦棒等の既存屋根(図示せず)が形成された既存屋根構造が下地αとなるものである。勿論、防水シート3を形成しない下地αでも良いものである。
【0008】
金属製屋根材Bは、例えば金属板(カラー鋼板、銅板、アルミニウム板、チタン板、ステンレス板、サンドイッチ鋼板、クラッド鋼板等)等をロール成形、プレス成形、押出成形、等によって形成したものである。勿論、屋根材Aの表面材として、金属製屋根材Bの代わりに窯業系素材、もしくは合成樹脂材(プラスチック)、等で形成してもよいものである。
【0009】
さらに説明すると、金属製屋根材Bは長尺板状であり、図1に示すように、略水平面状の化粧面4と、裏面5と、化粧面4の水下側の先端には下方に突出した段差化粧面6と、化粧面6の先端を上方に突出した垂直片6aと、垂直へ6aの先端を水上側へ突出した突出片6bと、段差化粧面6と化粧面4に沿って内側方に突出した上面7と、上面7の先端を下方に突出した最奥片8と、最奥片8の先端を水下側に突出した差込片9と、上面7と最奥片8と差込片9とから略コ字状の係合溝10を形成し、段差化粧面6と差込片9間に挿入間隙11を形成して雄型連結部12としたものである。
【0010】
また、図1に示すように、化粧面4の水上側端部には化粧面4の先端を上側に屈曲して形成した係合兼防水片13と、係合片13の先端を水下側へ屈曲し防水片13aと、係合兼防水片13の根本を水下側に屈曲した上面14と、上面14の先端を下方に屈曲し先端を水上側に突出した固定片15と、上面14と固定面15とから断面略コ字状に形成した前記差込縁7と嵌合する嵌合溝16を形成して雌型連結部17を形成したものである。また、化粧面4の端部には図3(b)に示すような係止片18を形成し、図3(a)に示すジョイナDの係合片19に係止することにより屋根材Aを下地α上に固定するものである。
【0011】

【0013】
挿入間隙11は、図2(a)に示すように挿入して屋根材A同士を連結する際に、段差化粧面6が邪魔にならないように、係合兼防水片13が係合溝10内に挿入できるように形成したものである。
【0014】
防水片13aは、係合兼防水片11の先端を水下側へ突出することにより、断面コ字状の溝を形成し、この溝により入ってこようとする風雨を、逆方向に回転させて排出し、防水性を向上するための形成したものである。
【0015】
また、図1において、段差化粧面6の高さをt、係合兼防水片13の高さをT、段差化粧面6から差込片9間での距離をh、係合兼防水片13の幅をHとすると、t≦T、h>Hの関係である。また、t=Tが下段の屋根材Aと上段の屋根材A間に間隙が形成されず、防水上有効である。なお、h=H+5〜10mm位が好ましい。
【0016】
裏打材Cは防水材、断熱材、吸音材、緩衝材、防火材、結露防止材、等として機能するものであり、不織布、合成樹脂製発泡シート(架橋化発泡ポリエチレンシート、等)、ロックウール、テックス(軟質繊維板)、ゴムシート、樹脂シート、等、あるいはこれらに遮音材、耐火材等を含浸、含有、混合、積層(一層、あるいは複数層)、サンドイッチ、等したものを使用することもできる。特に不織布は、縦糸と横糸を交差させて繊維から織物にする従来の方法と異なり、各種の繊維を接着剤等で結合した不織布等である。この不織布はまず繊維が平行に交差するか、また無秩序に配列された薄いフェルト状のものを接着剤で結合させるか、または主体となる繊維状態の中に別の熱可塑性繊維を混在させて、加熱および加圧して溶融し相互に結合させたりして作られたものである。勿論、素材自体に防水性の無いものには、樹脂材をコーティング、あるいは撥水剤、防水コーティング剤、等で防水機能を片面あるいは両面に付加したものである。
