Description

【０００１】
【発明の属する技術分野】
本発明は屋根用桟瓦に関する。
【０００２】
【従来の技術】
屋根用桟瓦の一形式として、図９に示すように桟部ａと尻部ｂとの角隅に桟側切込部ｃを設け、桟側切込部ｃの内側に桟側受け片ｄを設け、差込部ｅと頭部ｆとの角隅に桟側切込部ｃに対応する形状の差込側切込部ｇを設け、差込側切込部ｇに隣接して差込側凹部ｈを設けた屋根用桟瓦が知られている。
この種の桟瓦の葺設手順の一例を図１０及び図１１に模式的に示すに、桟瓦Ａの差込部ｅにその左横の桟瓦Ｂの桟部ａを重ね、桟瓦Ａの尻部ｂにその上段の桟瓦Ｃの頭部ｆを重ね、桟瓦Ｂの桟側切込部ｃに斜め上段の瓦Ｃの差込側切込部ｇを嵌めると共に桟瓦Ｂの桟側受け片ｄを桟瓦Ｃの差込側凹部ｈの下に潜り込ませ、桟瓦Ｄを桟瓦Ｂの尻部ｂと桟瓦Ｃの差込部ｅに重ねる。
【０００３】
【発明が解決しようとする課題】
従来の屋根用桟瓦では、瓦Ｂの尻側角隅は桟側受け片ｄを斜め上段の瓦Ｃの差込側凹部ｈの下に潜り込ませるので、瓦Ｃの頭部角隅と上段の瓦Ｄの頭部角隅で押さえ付けられることになり、強風が吹いてもめくり上がり難い。しかしながら、瓦Ｃの頭部角隅は横の瓦Ｄの頭部角隅で押さえられるだけであるため、瓦Ｂに比べめくり上がり易い。
本発明はかかる問題点に鑑み、強風によるめくり上がり防止効果に優れた屋根用桟瓦を提供することを目的とする。
【０００４】
【課題を解決するための手段】
請求項１に記載の発明は、瓦本体が山部と谷部から成る断面波形を有し、桟部と尻部との角隅に桟側切込部と該桟側切込部内に桟側受け片を設け、差込部と頭部との角隅に前記桟側切込部に対応する形状の差込側切込部と差込側凹部を設け、葺設したとき桟側切込部に斜め上段の瓦の差込側切込部が遊嵌すると共に、桟側受け片が斜め上段の瓦の差込側凹部の下に潜り込むように構成した屋根用桟瓦であって、前記差込側切込部内に差込側受け片を設けるとともに、前記桟側切込部に隣接して桟側凹部を設け、葺設したとき斜め上段の瓦の差込側受け片が桟側凹部に潜り込むようにしたことを特徴とする。
請求項２に記載の発明は、請求項１に記載の屋根用桟瓦において、前記桟部と尻部との角隅部に斜め上段の瓦の差込部と頭部との角隅部が嵌合する切欠部を形成したことを特徴とする。
【０００５】
【発明の作用・効果】
請求項１に記載の屋根用桟瓦によれば、下段の瓦がめくり上がろうとすると、下段の瓦の桟部と尻部との角隅に設けた桟側受け片が斜め上段の瓦の差込部と頭部との角隅に設けた差込側凹部に係止される。一方、上段の瓦がめくり上がろうとすると、上段の瓦の差込部と頭部との角隅に設けた差込側受け片が斜め下段の瓦の桟部と尻部との角隅に設けた桟側凹部に係止される。このように本発明に係る屋根用桟瓦は下段の瓦と、その斜め上段の瓦が互いに角隅においてめくり上がりを防止するように係止し合うので、高いめくり上がり防止効果を得ることができる。
請求項２に記載の屋根用桟瓦によれば、桟側切込部に加えて、さらに桟側切欠部を形成したので、桟側受け片と差込側凹部及び差込側受け片と桟側凹部とがより深く係止する。このため、一層めくり上がり防止効果が向上する。
【０００６】
【発明の実施の形態】
以下に本発明を図面に基づき説明するに、図１は本発明の一実施形態に係る屋根用桟瓦１０の表面を示す斜視図、図２は同屋根用桟瓦の裏面を示す斜視図である。当該桟瓦１０は逆椀型の山部１１と平坦な谷部１２を連ねた波形の断面形状を有し、桟部１３と尻部１４との角隅に桟側切込部１７が、また差込部１５と頭部１６との角隅に差込側切込部１８が形成されている。桟側切込部１７内には桟側受け片１９が設けられている。差込側切込部１８に隣接して差込部１５の裏面に差込側凹部２０が形成されている。桟側切込部１７を形成した桟部１３と尻部１４との角隅には、桟側切込部１７に隣接して桟側切欠部２１が形成され、この切欠部２１に隣接して裏面に桟側凹部２２が形成されている。また、差込側切込部１８内には差込側受け片２３が設けられている。
【０００７】
差込部１５は谷部１２に連ねて設けられ、上向きに反り返るように成形されている。差込部１５表面には斜めに複数本の排水溝１５ａが形成されている。差込部１５の側縁から尻部１４の側縁にかけては連続して水返し２４が突設されている。山部１１と谷部１２の頭部１６側端部には水垂れ１１ａ，１２ａが成形されている。山部１１の尻側頂部に釘穴２５が形成されている。
【０００８】
図３は桟側切込部を裏面側から見た斜視図である。図３に示すように、桟側受け片１９は瓦本体１０の厚みの略半分の厚みで成形され、桟側凹部２１は山部１１の裏面を直線的に切り欠いて断面略三角形に成形されている。そして、桟側受け片１９と桟側凹部２２は略面一となるように成形されている。
【０００９】
図４は差込側切込部１８を裏面から見た斜視図である。図４に示すように、差込側受け片２３は谷部１２の水垂れ１２ａの側端面から差込側切込部１８内に突出するように設けられている。
【００１０】
本実施形態に係る屋根用桟瓦１０の構造は以上の通りであって、該桟瓦１０を葺設するには、図５に模式的に示すように、まず桟瓦１０Ａの差込部１５に同じ段の左の桟瓦１０Ｂの桟部１３を重ねる。次ぎに図６に示すように、桟瓦１０Ｂの桟側切込部１７に右斜め上段の桟瓦１０Ｃの差込側切込部１８を嵌め合わせながら、桟瓦１０Ｃの頭部１６を桟瓦Ａの尻部１４に被せる。このとき、桟瓦１０Ｃの差込部１５と頭部１６との角隅を桟瓦Ｂの桟側切欠部２１に嵌め合わせ、さらに桟瓦１０Ｂの桟側受け片１９を桟瓦１０Ｃの差込側凹部２０の下に潜り込ませると共に、桟瓦１０Ｃの差込側受け片１８を桟瓦１０Ｂの桟側凹部２２の下に潜り込ませる。ついで、桟瓦１０Ｄを被せて、桟瓦１０Ｂの尻部１４を覆うと共に、桟瓦１０Ｂの桟側切込部１７と桟瓦１０Ｃの差込側切込部１８を覆う。
【００１１】
本実施形態に係る屋根用桟瓦によれば、下段の瓦１０Ｂがめくり上がろうとすると、下段の瓦１０Ｂの桟部１３と尻部１４との角隅に設けた桟側受け片１９が斜め上段の瓦１０Ｃの差込部１５と頭部１６との角隅に設けた差込側凹部２０に係止される。一方、上段の瓦１０Ｃがめくり上がろうとすると、上段の瓦１０Ｃの差込部１５と頭部１６との角隅に設けた差込側受け片２３が斜め下段の瓦１０Ｂの桟部１３と尻部１４との角隅に設けた桟側凹部２２に係止される。このように下段の瓦１０Ｂと、その斜め上段の瓦１０Ｃが互いに角隅においてめくり上がりを防止するように係止し合うので、高いめくり上がり防止効果を得ることができる。
【００１２】
また、桟側切込部１７に加えて、さらに桟側切欠部２１を形成したので、桟側受け片１９と差込側凹部２０及び差込側受け片１８と桟側凹部２２とがより深く係合する。このため、一層めくり上がり防止効果が向上する。
【００１３】
さらに、桟側受け片１９を瓦１０本体の厚みの略半分に成形し、桟側受け片１９と桟側凹部２２を面一にし、差込側受け片１８を谷部１２の水垂れ１２ａ部分から凸設したので、図７及び図８に示すように、瓦１０Ｂと瓦１０Ｃとの嵌合部分の段差が可及的に少なくなる。従って、瓦１０を葺いたときの外観が良くなる。
