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、特開２００２−５４２７１号公報には、図に示すように、瓦本体ａが山部ｂと谷部ｃから成る断面波形を有し、桟部ｄと尻部ｅとの角隅部裏面に桟側係止部ｆを形成し、差込部ｇと頭部ｈとの角隅部に差込側切欠部ｉを形成し、該差込側切欠部ｉの中に差込側係止片ｊを成形した屋根用桟瓦が開示されている。
この屋根用桟瓦ａは桟部ｄと尻部ｅの角隅部に斜め上段の瓦ａの差込側切欠部ｉを遊嵌し、下段の瓦ａの桟側係止部ｆの下に斜め上段の瓦ａの差込側係止片ｊを潜り込ませるように葺設する。こうすることで、上段の瓦ａの角隅部を斜め下段の瓦の角隅部で押さえ付けて強風による瓦ａのめくり上がりを防止するように構成されている。
【０００３】
【発明が解決しようとする課題】
ところで、一般に屋根用桟瓦の尻側の端部の表面には釉薬が施されていない部分があり、未施有部分には釘孔や水返しが設けられている。瓦は葺設するとき未施釉部分や釘孔、水返し等が表れないように上段の瓦の頭部側で覆い隠す必要がある。下段の瓦の未施釉部分が隠れるように上段の瓦を葺設したとき上段の瓦の、見付けといわれる頭部側端面が下段の瓦表面上に形成するラインは葺き合わせライン又は施工ラインと言われている。
図５に上記従来の屋根用桟瓦ａの葺き合わせラインｋを示す。葺き合わせラインｋは瓦１ａの桟部ｄと尻部ｅの角隅部の尻側端部が斜め上段の瓦２ａの差込側切欠部ｉの端面に当接するように瓦２ａを葺設したときの頭部側端面と一致するように設定されている。頭部側端面が葺き合わせラインｋと一致するように葺設すれば、上段の瓦２ａの頭部ｈによってちょうど真下の瓦１ａの未施釉部分や釘孔、水返しが覆われる。しかしながら、瓦ａの昇り足調整を行うべく、例えば瓦２ａに対して上段の瓦３ａを、瓦２ａの桟部ｄと尻部ｅの角隅部の桟側係止部ｆから差込側係止片ｊが外れないように限度まで上方へずらすと、瓦３ａの頭部端面によって形成されるラインｍの位置が葺き合わせラインｋより尻側へずれ、上段の瓦３ａの頭部ｈで下段の瓦２ａの未施釉部分を覆い隠すことができない。このように、従来の屋根用桟瓦は昇り足調整範囲が非常に狭いため、施工が甚だ不便である。
また、従来の屋根用桟瓦ａでは差込部ｇを流れ下った雨水が差込側係止片ｊに伝わり、そこから瓦ａの裏側へ侵入するおそれがある。
本発明はかかる問題点に鑑み、昇り足調整範囲が広く、また雨水の瓦裏側への侵入を防ぐことのできる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部裏面に桟側凹部を形成し、差込部と頭部との角隅部に差込側切欠部を形成すると共に該差込側切欠部の中に差込側係止片を成形し、桟部と尻部の角隅部に斜め上段の瓦の差込側切欠部を遊嵌し、桟側凹部の下に斜め上段の瓦の差込側係止片を潜り入れるよう葺設する屋根用桟瓦であって、桟部と尻部の角隅部の尻側端面に斜め上段の瓦の差込側切欠部の端面を当接するように葺設したとき、斜め上段の瓦の頭側端面が瓦の葺き合わせラインより下方に位置し、かつ桟側凹部の尻側端部が斜め上段の瓦の差込側係止片の頭側端部に重なるように葺設したとき、斜め上段の頭側端面が瓦の葺き合わせラインにほぼ整列するように構成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、前記差込側係止片の側縁に、差込側端部に凸設した水返しに沿って補助水返しを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、上段の瓦を、下段の瓦の桟部と尻部の角隅部の尻側端面に差込側切欠部の端面が当接する位置と、下段の瓦の桟側凹部の尻側端部が差込側係止片の頭側端部に重なる位置の間にあるように葺設すれば上段の瓦の頭部によって下段の瓦の葺き合わせラインから尻側の部分を覆い隠すことができるので、瓦の差込側係止片の縦寸法分が瓦の昇り足調整可能範囲となる。このため、昇り足調整範囲が広く、瓦の葺設作業が容易になる。
請求項２に記載の発明によれば、差込側係止片の端部に水返しを凸設したので、係止片を伝って雨水が瓦の裏側に侵入するのを防止できる。
【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との角隅部の裏側に平坦な桟側凹部１５が形成され、角隅部の表面には桟側凹部１５の厚みを増して補強するため凸湾曲部１６が成形されている。
【０００７】
桟瓦１０の谷部１２に平坦な差込部１７が上向きに反り返るように連設されている。差込部１７の側縁から尻部１４の側縁にかけては連続して水返し１８，１９が突設されている。瓦本体１０の差込部１７と頭部２０の角隅部には差込側切欠部２１が形成され、差込部１７の頭部側端面に平坦な差込側係止片２２が連設され、切欠部２１中に突出している。差込部１７の頭部側端部表面の差込側角隅部には差込部１７表面を伝って流れ下る雨水を差込側係止片２２へと導くため水返し１８に連なる略三角形の傾斜面２３が形成されている。また、差込側係止片２２の側縁には雨水が瓦本体１０の裏側へ侵入するのを防止するため水返し１８に沿って水返し２４が凸設されている。
【０００８】
瓦本体１０の差込側谷部１２の側縁にも瓦本体表面から雨水が差込部１７へ流れ込むのを防止するため水返し２５が凸設されている。また、両谷部１２の尻側よりに雨水の尻側への流れを阻止するため横溝２６が形成されている。瓦１０本体表面は頭部２０端部からほぼこの横溝２６までの領域に釉薬が施され、横溝２６から尻側の部分は未施釉部分となっているので、この横溝２６が瓦１０の葺き合わせラインを兼ねている。そして、山部１１の未施釉部分の頂部と桟側谷部に釘孔２７が形成されている。瓦１０本体裏面の尻側端部には桟木に瓦１０を掛止するための爪２８が２本凸設されている。
【０００９】
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３に模式的に示すように、まず瓦１０Ａの桟部１３と尻部１４の角隅部に斜め上段の瓦１０Ｂの差込側切欠部２１を遊嵌し、瓦１０Ａの桟側凹部１５の下に瓦１０Ｂの差込側係止片２２を潜り込ませる。そして、瓦１０Ｂの横に瓦１０（図示略）を頭部２０端面が整列するように並べて瓦１０Ａの未施釉部分をこの瓦１０（図示略）で覆い隠す。同様にして瓦１０Ｂの斜め上段に瓦１０Ｃを葺設する。このように葺設することで、瓦１０Ａの角隅部で瓦１０Ｂの角隅部が押さえられ、瓦１０Ｂで瓦１０Ｃが押さえられるので、強風による瓦１０のめくり上がりを防止できる。
【００１０】
図３において、瓦１０Ｂは瓦１０Ａに対し、差込側切欠部２２の端面（差込部１７の頭側端面）が瓦１０Ａの角隅部の尻側端面に当接するように葺設されている。このときの瓦１０Ｂの横に並べる瓦１０の頭部２０端面の描くラインを図に２点鎖線ｎで示す。ラインｎは瓦１０Ａの葺き合わせラインに相当する横溝２６から所定寸法だけ頭部２０側に寄った位置にある。一方、瓦１０Ｃは瓦１０Ｂに対し、瓦１０Ｂの桟側凹部１５の尻側端部が瓦１０Ｃの差込側係止片２２の頭側端部から外れない限界の位置に葺設されている。このときの瓦１０Ｃの横に並べる瓦１０の頭部２０端面の描くラインを２点鎖線ｐで示す。ラインｐは瓦１０Ｂの横溝２６にほぼ整列する位置にある。
【００１１】
図３に示すように、瓦１０Ａ未施釉部分が瓦１０Ｂの頭部２０で覆い隠され、瓦１０Ｂの未施釉部分が瓦１０Ｃの頭部２０で覆い隠される。従って、瓦１０の差込側係止片２２の縦寸法分が瓦１０の昇り足調整可能範囲となるので、昇り足調整範囲が広く、瓦１０の葺設作業が容易になる。
また、差込側係止片２２の端部に水返し２４を凸設したので、係止片２２を伝って雨水が瓦１０の裏側に侵入するのを防止できる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a roof tile.
[0002]
[Prior art]
As one type of the roof tile, Japanese Patent Application Laid-Open No. 2002-54271 discloses that as shown in the figure, a tile body a has a cross-sectional waveform composed of a peak b and a valley c, and a rail d and a butt e. A cross-section locking portion f is formed on the back surface of the corner, and a plug-side notch i is formed at a corner of the insertion portion g and the head h. Discloses a roof tile having a plug-side locking piece j formed therein.
In the roof tile a, the insertion side notch i of the upper tile a is loosely fitted at the corners of the cross section d and the buttocks e. The roof tile a is laid so that the insertion side locking piece j of the upper tile a is sunk. By doing so, the corners of the upper tile a are pressed down by the corners of the lower diagonal tile to prevent the tile a from turning up due to strong wind.
[0003]
[Problems to be solved by the invention]
By the way, generally, there is a portion where the glaze is not applied on the surface of the bottom end of the roof tile, and a nail hole or a water return is provided in the uncoated portion. When laying roof tiles, it is necessary to cover them with the top side of the roof tiles so that unglazed parts, nail holes, water return etc. do not appear. When the upper tile is laid so that the unglazed part of the lower tile is hidden, the line where the top end of the upper tile, which is said to be found, is formed on the lower tile surface is called a roofing line or a construction line. Has been done.
FIG. 5 shows a roofing line k of the conventional roof tile a. The roofing line k is laid on the tile 2a so that the buttocks end of the corners of the cross section d and the butt part e of the tile 1a abut on the end face of the insertion side cutout i of the tile 2a in the upper diagonal. It is set to coincide with the head-side end face at the time. If the head side end surface is laid so as to coincide with the roofing line k, the unglazed portion, the nail hole and the water return of the tile 1a just below are covered by the head h of the upper tile 2a. However, in order to adjust the climbing foot of the tile a, for example, the upper tile 3a is placed on the tile 2a by inserting the upper tile 3a from the cross-section locking portion f at the corners of the cross section d and the buttocks e of the roof 2a. If the stopper j is displaced upward to the limit so that it does not come off, the position of the line m formed by the head end surface of the tile 3a is shifted to the buttocks side from the roofing line k, and the lower part is moved by the head h of the upper tile 3a. Unglazed part of the roof tile 2a cannot be covered. As described above, since the conventional roof tile has a very narrow range of adjusting the climbing foot, the construction is extremely inconvenient.
Further, in the conventional roof tile a, there is a possibility that the rainwater flowing down the insertion portion g is transmitted to the insertion side locking piece j and enters the back side of the roof tile a therefrom.
SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a roof tile that has a wide range for adjusting a rising foot and that can prevent rainwater from entering a back side of a tile.
[0004]
[Means for Solving the Problems]
According to the first aspect of the present invention, the roof tile body has a cross-sectional waveform consisting of a peak and a valley, a cross-section-side recess is formed on the back surface of the corner of the cross-section and the bottom, and the plug-in section and the head A notch at the insertion side is formed at the corner of the roof, and a locking piece at the insertion side is formed in the notch at the insertion side. The roof tile has a cut-in side notch, which is loosely fitted, and is laid so that the insertion-side locking piece of the tile at the upper diagonal is sunk under the cross-side recess. When laying so that the end face of the insertion side cutout part of the upper diagonal tile is in contact with the end face on the buttocks side, the head end face of the upper diagonal tile is located below the roofing line of the tile, and the pier side recess When the bottom end of the roof is laid so that it overlaps the head end of the insertion-side locking piece of the upper tile, the upper end of the upper diagonal line is almost aligned with the roofing line of the tile. The feature is that That.
According to a second aspect of the present invention, in the roof tile according to the first aspect, an auxiliary water return is protruded along a water return protruding from an end of the insertion side at a side edge of the insertion side locking piece. It is characterized by having been established.
[0005]
[Action and Effect of the Invention]
According to the roof tile according to claim 1, the upper tile is positioned at a position where the end face of the insertion-side cutout portion abuts against the tail end face of the corner of the lower tile and the corner of the lower tile. If the roof of the roof tile is laid so that the tail end of the recess on the beam side of the roof tile overlaps with the head end of the plug-in side locking piece, the roof line of the lower tile is laid by the head of the upper tile Since the portion on the butt side can be covered and hidden, the vertical dimension of the insertion side locking piece of the tile becomes the adjustable range of the climbing foot of the tile. For this reason, the range of adjustment of the climbing feet is wide, and the work of laying tiles is facilitated.
According to the second aspect of the present invention, since the water return is protruded at the end of the insertion-side locking piece, it is possible to prevent rainwater from entering the back side of the tile through the locking piece.
