Description

【０００１】
【発明の属する技術分野】
この発明は、２枚の部材をヒンジ継手で取り付けた屋根パネル及び屋根構造に関するものである。
【０００２】
【従来の技術】
従来、切妻屋根式屋根パネルとしては、図９（ａ）に示すように、所定の幅と長さのパネル２，３を一組としてパネル２，３の棟一端部の端面同志をヒンジ継手４，５で回動可能で結合して折りたたまれるものが考えられている（実開平４−６３７１６号公報）。
【０００３】
このヒンジ継手４は互いに回動可能なヒンジ部材４ａ，４ｂと、ヒンジ継手５は互いに回動可能なヒンジ部材５ａ，５ｂとを有する。そして、ヒンジ部材４ａ，５ａはパネル２の端面に固定され、ヒンジ部材４ｂ，５ｂはパネル３の端面に固定されている。
【０００４】
【発明が解決しようとする課題】
しかしながら、従来の切妻屋根式屋根パネル１にパネル２，３の内側に天井部材７，７を配設した場合には、天井部材７，７の厚み分パネル２，３先端２ｂ，３ｂが間隔Ｃ分拡がるとともに、ヒンジ継手４，５の結合部４ｃ，５ｃが両天井部材７，７表面から延長した交点近傍の位置となり、パネル２，３先端２ｂ，３ｂが間隔Ｃ分拡がるとともに、ヒンジ継手４，５の結合部４ｃ，５ｃが棟材６側に入った位置となってしまう。
【０００５】
そして、建物によって天井部材７，７の厚みが変わると、パネル２，３先端２ｂ，３ｂの間隔Ｃが変わるとともに、ヒンジ継手４，５の結合部４ｃ，５ｃの位置も変わっしまう。また、屋根勾配が変わると、パネル２，３先端２ｂ，３ｂの間隔Ｃが変わり、天井部材７，７の厚みや屋根勾配が変わる都度、ヒンジ継手４，５の結合部４ｃ，５ｃを回避するとともに、パネル２，３先端２ｂ，３ｂを載置する棟材６の設計に伴う母屋等の妻フレーム８の設計が必要となり、棟材６等の設計が複雑になってしまうとの問題があった。
【０００６】
そこで、この発明の目的は、屋根パネルの内側に配設される天井部材の厚みや屋根勾配が変わっても棟材等の設計が標準化できる屋根パネル及び屋根構造を提供することにある。
【０００７】
【課題を解決するための手段】
この目的を達成するため、この発明の請求項１は、２枚のパネルの棟側端面にヒンジ継手の互いに回動可能な２枚のヒンジ板をそれぞれ固定し、前記２枚のパネルがヒンジ継手の結合部を境に拡げられて棟材に載置される屋根パネルであって、
前記２枚のヒンジ板は互いに合わせられる基板部と互いに開く方向に折り曲げれ且つ前記パネルの端面に固定された固定板部から形成されていることを特徴としている。
【０００８】
このように構成された請求項１に記載のものでは、パネルの端面に固定された固定板部が基板部に対して互いに開く方向に折り曲げれているので、２枚のパネルがヒンジ継手の結合部を境に拡げられても先端同志が当接し、２枚のパネルの先端間隔が拡がらず、棟材が２枚のパネルの先端部を当設する形状に統一でき、載置する棟材等の設計が標準化できる。
【０００９】
請求項２は、２枚のパネルの棟側端面にヒンジ継手の互いに回動可能な２枚のヒンジ板をそれぞれ固定し、前記２枚のパネルがヒンジ継手の結合部を境に拡げられて棟材に載置される屋根構造であって、
前記２枚のヒンジ板は互いに合わせられる基板部と互いに開く方向に折り曲げれ且つ前記パネルの端面に固定された固定板部から形成され、棟材には上方に開口した凹部を形成するとともに、前記凹部の両側に前記各パネルの傾斜と同じ角度で傾斜する傾斜面を形成し、この凹部に前記ヒンジ継手の結合部を挿入することにより前記パネルの端部内面が前記傾斜面に当接することを特徴としている。
【００１０】
このように構成された請求項２に記載のものでは、棟材の上方に開口した凹部にヒンジ継手の結合部を挿入するとともに、凹部の両側に各パネルの傾斜と同じ角度で傾斜する傾斜面に各パネルの端部内面が当接するので、ヒンジ継手の結合部を棟材の凹部に挿入し、２枚のパネルがヒンジ継手の結合部の境に拡げられるとともに、棟材に屋根パネルが確実に装着できる。
【００１１】
また、請求項３は、前記ヒンジ継手の基板部と固定板部との曲がり部が前記開口部に位置することを特徴としている。
【００１２】
このように構成された請求項３に記載のものでは、ヒンジ継手の基板部と固定板部との曲がり部が棟材の凹部開口部に位置するので、２枚のパネルがヒンジ継手の結合部を境に拡げられても２枚のパネルの先端同志を確実に当接することができる。
【００１３】
【発明の実施の形態】
以下、この発明の実施の形態を図１から図８を基に説明する。
【００１４】
図２において、符号１０は建物、１１は建物１０の妻面、１２は切妻屋根、１２ａ，１２ｂは切妻屋根１２の軒先、１３は軒先１２ａに沿って延びる軒樋、１４は軒樋１３に設けたあんこう、１５はあんこう１４に集まる雨水を図示しない建物１０の下にある排水口に流す雨樋、１６は棟である。
【００１５】
この切妻屋根１２は、図３に示すように、複数の屋根パネル２０を棟１６方向に並設している。
【００１６】
図１は、この発明の実施の形態の屋根パネル２０を棟木４０に取り付けた状態を示すものである。
【００１７】
屋根パネル２０は、棟１６から軒先１２ａまでの左のパネル２１と、棟１６から軒先１２ｂまでの左のパネル２２と、ヒンジ継手３０とから構成されている。
【００１８】
左・右のパネル２１，２２は、図４に示すように、外側の外板２１ａ，２２ａと、内側の内板２１ｂ，２２ｂと、この外板２１ａ，２２ａと内板２１ｂ，２２ｂとの両端の間に介在して棟１６方向に設けられた板材２３，２４と、内板２１ｂ，２２ｂに設けた天井部材２５とからなっている。この左・右のパネル２１，２２の寸法は、棟１６方向に均等に分割された幅と棟１６から軒先１２ａ，１２ｂまでの長さとなっている。また、板材２３が棟１６側で、板材２４が軒先１２ａ，１２ｂ側となる。
【００１９】
また、ヒンジ継手３０は、図５に示すように、結合部３１と、この結合部３１を境に左・右のヒンジ板３２，３３とからなっている。このヒンジ板３２，３３が結合部３１を境に互いに合わせられる基板部３２ａ，３３ａと、曲がり部３２ｃ，３３ｃから互いに開く方向に所定角度θａに折り曲げれた固定板部３２ｂ，３３ｂとからなっている。この固定板部３２ｂ，３３ｂには、左・右のパネル２１，２２の板材２３面にネジ等で固定する固定穴３４…，３５…が形成されている。このヒンジ板３２，３３は、板厚を数ミリ程度の金属製である。
【００２０】
この固定板部３２ｂ，３３ｂの折り曲げ角度θａは、左・右のパネル２１，２２を屋根勾配角度θに拡げた場合に、結合部３１に対して基板部３２ａ，３３ａのなす角度θｂ分を加味して屋根勾配角度θより大きくしている。
【００２１】
棟木４０は、上方に開口した挿入溝４１と、この挿入溝４１の開口部４２から左右下方に傾斜した傾斜部４３，４４とを形成している。この傾斜部４３，４４の角度は屋根勾配角度θとなっている。
【００２２】
この挿入溝４１にはヒンジ継手３０の結合部３１と基板部３２ａ，３３ａが挿入されていて、挿入溝の開口上部では基板部３２ａ，３３ａに対して互いに開く方向に折り曲った先端同志が当接され、先の固定板部３２ｂ，３３ｂには左・右のパネル２１，２２が傾斜部４３，４４に当接されている。この傾斜部４３，４４の傾斜角度に合わせた母屋等の妻フレーム４５が設けられている。
