特開2002−038658号公報
【特許文献2】
特開2002−155602号公報
【0004】
【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。
【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化粧面の水上側の先端には上方に突出した防水片と、防水片の先端を水上側に突出した嵌合片を形成し、化粧面の水下側の先端には下方に垂下した段差化粧面と、化粧面の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】
【発明の実施の形態】
以下に図面を用いて本発明に係る屋根材について詳細に説明する。図1は金属製屋根材Bと裏打材Cよりなる屋根材Aの代表的一例を示す説明図、図2は取付具Dを示す断面図、図3(a)、(b)は屋根材Aの施工状態を示す説明図、図4(a)、(b)はジョイナE(Fはパッキング材)とその施工状態を示す説明図である。図中、αは下地、βは釘等の固定具を示している。なお、図4(b)は図3(a)のa−a部端面図である。
【0007】
下地αは、新築の際は図3(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。

【0011】
挿入間隙11は、図3(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、嵌合片14が係合溝10内に挿入できるように形成したものである。
【0012】
段差化粧面6は、段差を形成し屋根に重厚感を付与すると共に、内部に空間を形成し、直接、風雨が屋根材Aの連結部に当たらないように形成すると共に、屋根材A同士の連結の際に形成される連結部の隙間、所為、段差化粧面6の先端部分と、嵌合片14の先端部分が上下に存在するような形状にすることにより、防水性を向上するものである。
【0013】
嵌合片14は、防水片13の先端を水上側へ突出することにより、断面コ字状の嵌合溝15を形成し、差込片9を嵌合溝15に挿入することにより、屋根材A同士を連結するものである。

【0015】
屋根材Aの固定には、図2に示すような固定面20と支持面21よりなる取付具Dを使用し、図3(a)、(b)に示すように施工するものである。なお、取付具Dは短尺(20mm〜60mm位)のものを使用するものである。勿論、長尺状でも可能である。
【0016】
以上説明したのは本発明に係る屋根材の一実施例にすぎず、図4(a)、(b)〜図8(a)〜(c)に示すように形成することもできる。
【0017】
Gは裏面材であり、金属材、あるいはアスベスト紙、クラフト紙、アスファルトフェルト、金属箔(Al、Fe、Pb、Cu)、合成樹脂シート、ゴムシート、布シート、石膏紙、水酸化アルミ紙、ガラス繊維不織布等の1種、または2種以上をラミネートしたもの、あるいは防水処理、難燃処理されたシート等からなるものである。
