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、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、前記桟側受け片を瓦本体の厚みの略半分に成形し、前記桟側受け片と前記桟側凹部の裏面を面一にし、かつ前記差込側受け片を前記谷部の水垂れ部分から凸設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。
また、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。
さらには桟側受け片を瓦本体の厚みの略半分に成形し、桟側受け片と桟側凹部を面一にし、差込側受け片を谷部の水垂れ部分から凸設したので、瓦と瓦との嵌合部分の段差が可及的に少なくなる。従って、瓦を葺いたときの外観が良くなる。

【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。
