Description

【0001】
【発明の属する技術分野】
本発明は、屋根に配置する桟瓦に関する。
【0002】
【従来の技術】
和風の桟瓦は、図13(a)で示すように、桟部12と差込部14、及び尻部16と頭部18がそれぞれ相対する略四角形で構成されており、桟部12と差込部14を横断する断面が、図13(b)で示すように波型に形成されている。桟瓦の裏面の尻部側には、瓦桟に引っ掛けるための突起20が設けられている。
【0003】
桟瓦の施工は、一般的に以下のように行われる。一の桟瓦を瓦桟に掛止し、一の桟瓦における差込部14の表面に、他の桟瓦における桟部12の裏面を重ね合わせるようにして、該一の桟瓦の右横に他の桟瓦を配置する。この作業を右横方向に繰り返し行い、横方向の配置が右端まで終了したならば、一段上の瓦桟に、桟瓦を左から右方向に掛止して配置している。このように桟瓦は、屋根板の軒側から棟側に向かって配置される。桟瓦は、突起20で瓦桟に掛止される他に、一部の桟瓦が釘を用いて瓦桟に固定されている。
【0004】
上述の如き桟瓦の施工では、地震による縦横の揺れや、台風等による強風などで、桟瓦が飛ばされてしまい、危険であった。そこで、従来から、様々な手法を用いて桟瓦の飛散を防止する発明が為されている。
【0005】
例えば、桟瓦に金具を取り付け、その金具を鋼索等で連結し、鋼索等を屋根に固定することで桟瓦を屋根に固定させる発明(特許文献1参照)や、桟瓦における、隣接する桟瓦と係止し合う部位の形状を工夫することで、桟瓦が浮き上がらないようにした発明(特許文献2、特許文献3、特許文献4参照)がある。

【0007】
【発明が解決しようとする課題】
しかしながら、これら従来の発明においては、次のような欠点があった。特許文献1に例示する発明においては、桟瓦の施工が容易でなく、施工後の屋根の見栄えが良くない。また、特許文献2、特許文献3、特許文献4に例示する発明においては、互いに係止し合う桟瓦の部位が、小さい面積同士で係止し合うことから、その係止し合う小さな面積の部位に大きな力が加わると、係止し合う部位が割れ落ち、桟瓦が飛散することも考えられる。
【0008】
また、桟瓦同士の係止により桟瓦の浮き上がりを防止する発明の技術思想では、桟瓦同士が重なる部分において桟瓦同士が係止し合うのであるが、その桟瓦同士が重なる部分の面積は、桟瓦全体の面積のごく一部であるから、係止し合う部位の面積を大きくすることに限界がある。
【0009】
そこで、本発明の目的は、桟瓦同士が固く連結され、且つ、掛止し合う部分も堅牢であり、加えて施工が容易で、施工後、美しい外観を呈することができる桟瓦を提供することにある。
【0010】
【課題を解決するための手段】
本発明に係る桟瓦は、桟部、差込部、尻部、頭部で構成され、前記桟部の流れ方向に沿った突条を備え、前記突条の尻部側の一端面が、前記桟部の瓦表面から尻部側に傾斜して立ち上がり、前記突条の頭部側の他端面が、前記桟部の瓦表面から尻部側に傾斜して立ち上がることを特徴とする。本発明における流れ方向とは、桟瓦において雨水流れる方向のことをいう。言い換えると、桟瓦における尻から頭に向かう方向のことをいう。
【0011】
更に、本発明に係る桟瓦は、上述の構成に加え、前記一端面が、立ち上がり且つ、前記桟部から差込部方向に進むに従い、流れ方向に傾斜し、前記他端面が、立ち上がり且つ、前記桟部から差込部方向に進むに従い、流れ方向に傾斜することを特徴とする。
【0012】
更に、本発明に係る桟瓦は、上述の構成に加え、前記突条の尻側の一端面が、前記尻部端面の内方に控えて位置し、前記突条の他端面が、頭部より延出していることを特徴とするものである。
【0013】
更に、本発明に係る桟瓦は、上述の構成に加え、前記桟部における、前記一端面の近傍における瓦表面に、流れ方向に傾斜した水切り溝を設けたことを特徴とする。
【0014】
また、本発明に係る桟瓦の施工方法は、一の桟瓦における尻部の表面に、他の桟瓦における頭部の裏面が重ね合わされる桟瓦の施工方法であって、前記一の桟瓦における突条の尻部側の一端面と、他の桟瓦における突条の頭部側の他端面とを面合わせし、他の桟瓦を配置するステップを含むことを特徴とする。
【0015】
【発明の実施の形態】
本発明の実施の形態に係る桟瓦を図面に基づき説明する。以下で、従来例と重複する構成要素については、同符号を付してその詳細な図示又は説明を省略する。図1に示すように、本発明における桟瓦10は、桟部12、差込部14、尻部16、頭部18で構成された桟瓦において、桟部12の流れ方向に沿った突条22を備え、突条22の尻部16側の一端面22aが、桟部12の瓦表面から尻部16側に傾斜して立ち上がり、突条22の頭部18側の他端面22bが、桟部12の瓦表面から尻部16側に傾斜して立ち上がることを特徴とする。
【0016】
また、本発明における桟瓦10は、上述の構成に加え、一端面22aが、桟部12から差込部14方向に進むに従い、流れ方向に傾斜し、他端面22bが、桟部12から差込部14方向に進むに従い、流れ方向に傾斜することを特徴とする
【0017】
図2に示すように、桟瓦10には、桟部12の尻部16側の端部に尻切込部24と、差込部14の頭部18側の端部に頭切込部26が設けられている。尻切込部24は、桟部12の尻部16側の隅部が、尻切込幅と尻切込長さで切り取られている。頭切込部26は、差込部14の頭部18側の隅部が、頭切込幅と頭切込長さで切り取られている。ここで、幅とは、桟部12と差込部14を結ぶ線の方向のことを示し、長さとは、尻部16と頭部18を結ぶ線の方向のことを示す。
【0018】
図2に示すように、桟瓦10の尻部16側の表面と差込部14側の表面に段差による水切り28が設けられており、差込部14側には、流れ方向に沿って凸条の水切り28が設けられている。桟瓦10の尻部16側には釘を挿通するための貫通孔30が設けられいる
【0019】
突条22は、桟瓦10の桟部12において、流れ方向に沿って設けられている。図1に示すように、この突条22は断面が略カマボコ型に形成されており、従来の桟瓦における桟部12の部分に突出し、且つ、流れ方向に沿ってテーパー状に先細り、桟部12と一体となって設けられている。
【0020】
図1に示すように、突条22の尻部16側の一端面22aは、桟瓦10の尻部16端面から流れ方向の内方、すなわち、桟部12の尻切込部24から更に内方の瓦表面から尻部16側方向に斜めに立ち上がっている。ここで、桟部12の瓦表面とは、桟部12における突条22が突出していない部分の表面のことを示す。詳しくは、図3に示すように、突条22の尻部16側の一端面22aは、尻切込部24から更に内方に、頭切込長さ程度離れた位置から立ち上がり、瓦表面から垂直に立ち上がった面を基準とすると、尻部16側に約18度傾いて立ち上がっている。
【0021】
突条22の尻部16側の一端面22aは、図2に示すように、桟部12から差込部14方向に進むに従い、流れ方向に緩やかに傾斜している。詳しくは、図2において流れ方向と垂直に交わる線を基準にすると、流れ方向に約5度傾いている。
【0022】
突条22の頭部18側の他端面22bは、図2に示すように、頭部18より延出した掛止部32に備わる。この掛止部32は、突条22の頭部18側に、桟部12側よりも差込部14側が斜めに突出して延設されている。他端面22bは、この掛止部32の端面に設けられている。ここで掛止部32とは、突条22における桟瓦10の頭部18側の端面から、流れ方向に延設されている部分のことを示す。
【0023】
突条22の頭部18側の他端面22bは、突条22の頭部18側端部から尻部16側方向に斜めに立ち上がっている。詳しくは、図3に示すように、突条22の頭部18側の他端面22bは、突条22の尻部16側の一端面22aと同じ傾斜で立ち上がっている。
【0024】
突条22の頭部18側の他端面22bは、図2に示すように、桟部12から差込部14方向に進むに従い、流れ方向に緩やかに傾斜している。詳しくは、図2に示すように、突条22の頭部18側の他端面22bは、突条22の尻部16側の一端面22aと同じ傾斜で傾いている。
【0025】
つまり、一の桟瓦10aにおける突条22の一端面22aと、他の桟瓦10bにおける突条22の他端面22bとは同じ傾斜で傾いている。言い換えると、同じ桟瓦10における、突条22の尻部16側の一端面22aと、頭部18側の他端面22bは、同じ傾斜で傾いている。
【0026】
図2に示すように、桟部12の瓦表面には、山型状の水切り溝34を設けている。この山型状の水切り溝34は、裾野部分が流れ方向に向くように設けている。
【0027】
次に、本発明における桟瓦10の施工方法を、本発明における桟瓦10の作用と共に説明する。図5に示すように、本発明における桟瓦10は、屋根板に間隔を置いて固定された瓦桟に掛止される。桟瓦10の尻部16裏面に設けられた突起20を瓦桟に掛止することによって、桟瓦10が屋根板の上に配置される。桟瓦10は、貫通孔30に釘を挿通させ、釘を瓦桟に打ち込むことにより、桟瓦10の尻部16が固定される。
【0028】
桟瓦10の施工は、軒側から棟側に向かって施工される。桟瓦10は軒先の左側から右側方向に配置され、施工を行う屋根の右端まで配置された後、一段上の瓦桟に桟瓦10が掛止される。ここで、左および右とは、施工を行う屋根を正面に見て、左および右と表現している。
【0029】
一の桟瓦10a(この場合は、軒先の桟瓦)における突条22の傾斜した一端面22aに、一の桟瓦10aの上方側に配置される他の桟瓦10b(この場合は、一段上の瓦桟に掛止される桟瓦)における突条22の傾斜した他端面22bが面合わせされる。他の桟瓦10bは、一の桟瓦10aの傾斜している一端面22aに、他の桟瓦10bの他端面22bを面合わせさせるために、斜め上方から滑り込ませるように一の桟瓦10aの突条22に嵌め込まれる。上述の作業を桁行き方向(左から右に向かう方向)に繰り返すことで桟瓦10が施工される。
【0030】
図4及び図5に示すように、一の桟瓦10aにおける突条22の一端面22aに、他の桟瓦10bにおける突条22の他端面22bが面合わせされることで、他の桟瓦10bの突条22が、一の桟瓦10aの突条22に規制されるので、他の桟瓦10bにおける頭部18の浮き上がりを防止することができる。
【0031】
また、図5及び図6に示すように、他の桟瓦10bの掛止部32が、他の桟瓦10bの裏面に配置される一の桟瓦10aの桟部12表面に覆い被さっているので、一の桟瓦10aの浮き上がりを防止することができる。
【0032】
また、図4及び図5に示すように、桟部12の瓦表面には、裾野部分が流れ方向に向く山型状の水切り溝34を設けている。これにより、一の桟瓦10aの一端面22aと、他の桟瓦10bの他端面22bとの隙間から瓦表面に流れ込んだ雨水を、桟瓦10の谷部に流し込むことができる。よって、桟瓦10の突条22の隙間から雨水が流れ込むことによる、家屋の雨漏りを防止することができる。
【0033】
また、図6に示すように、桟瓦10の突条22の一端面22aが、桟部12から差込部14に進むに従い、流れ方向に傾斜していることから、一端面22aと、この桟瓦10の上方に配置された桟瓦10の他端面22bとの間の隙間に流れ込んだ雨水を桟瓦10の谷部に流し込むことができる。よって、一端面22aと他端面22bとの間に雨水が溜まらないことから、桟瓦10に突条22を設けることによって、家屋の雨漏りの原因となることはない。
【0034】
また、図4に示すように、他の桟瓦10bは、一の桟瓦10aの傾斜している一端面22aに、他の桟瓦10bの他端面22bを面合わせさせるために、斜め上方から滑り込ませるように一の桟瓦10aの突条22に嵌め込んでいる。よって、一の桟瓦10aに他の桟瓦10bを掛止させる際に、特別な部材(例えば、引っ掛け金具等)を使用しないことから、桟瓦の施工が容易である。
【0035】
更に、図4及び図6に示すように、桟瓦10の桟部12に設けられた突条22が、軒から棟方向に連なるように見える。よって、本発明の桟瓦10を屋根全体に配置すると、平瓦と丸瓦からなる所謂本葺きの如く、美しい外観を呈することができる。
【0036】
尚、本発明はその趣旨を逸脱しない範囲で当業者の知識に基づき種々なる改良、修正、変形を加えた態様で実施できるものである。
【0037】
例えば、図7に示すように、万十角瓦(右)の桟部12に突条22を設けることも、本発明の範囲に含まれる。また、図8に示すように、袖瓦(右)の桟部12に突条22を設けることも、本発明の範囲に含まれる。また、図示しないが、角瓦(右)、万十軒瓦、一文字角瓦(右)、一文字軒瓦等の、使用される場所により異なる形状の桟瓦10の桟部12に突条22を設けることも、本発明の範囲に含まれる。
【0038】
また、桟部12に設けられる突条22の断面も、実施形態例に限定されない。例えば、図9に示すように、断面円弧状にすることや、図10に示すように、断面山型にすることも、本発明の範囲に含まれる。
【0039】
また、突条22の一端面22aおよび他端面22bの形状も、実施形態例に限定されない。例えば、図11に示すように、突条22の尻部16側の一端面22aに、凹状の溝部38を設け、突条22の頭部18側の他端面22bに、凹状の溝部38と嵌合する凸状の突部36を設けることも、本発明の範囲に含まれる。また、図12に示すように、突条22の尻部16側の一端面22aに、ノコギリ状の突部36を設け、突条22の頭部18側の他端面22bに、突部36と嵌合するノコギリ状の溝部38を設けることも、本発明の範囲に含まれる。これにより、一の桟瓦10aの突部36又は溝部38と、他の桟瓦10bの突部36又は溝部38をを嵌合させることで、他の桟瓦10bを施工する際の桟瓦10の位置決めが容易になる。よって、桟瓦10の施工がより容易になる。
【0040】
【発明の効果】
本発明における桟瓦によれば、一の桟瓦における突条の傾斜した一端面(尻部側)と、一の桟瓦の上方側に配置された他の桟瓦における突条の傾斜した他端面(頭部側)とが、面合わせされることにより、互いに規制されるので、強風や地震等による他の桟瓦頭部の浮き上がりを防止することができる。
【0041】
また、本発明における桟瓦によれば、一の桟瓦の上方に配置された他の桟瓦の掛止部が、一の桟瓦における桟部の瓦表面に係止されることにより、一の桟瓦が他の桟瓦に押さえつけられるので、強風や地震等による一の桟瓦の浮き上がりを防止することができる。
【0042】
また、本発明における桟瓦によれば、一の桟瓦の一端面と、他の桟瓦の他端面とが面合わせされている部分が、桟部から差込部方向に進むに従い、流れ方向に傾斜している。よって、桟瓦が差込部から桟部に向かう方向(左方向)にずれるのを防止することができる。また、桟瓦の頭切込部に右下の桟瓦の尻切込部が当接することから、桟瓦は桟部から差込部に向かう方向(右方向)にずれることはない。よって、本発明における桟瓦は、左及び右のどちらの方向にも、ずれることを防止することができる。
【0043】
また、本発明における桟瓦によれば、一の桟瓦における突条の一端面に設けられた溝部(又は突部)に、一の桟瓦の上方に配置された、他の桟瓦における突条の他端面に設けられた突部(又は溝部)が嵌合することにより、一の桟瓦と他の桟瓦の連結がより強固になる。よって、強風や地震等による他の桟瓦頭部の浮き上がりをより一層防ぐことができる。また、突部と溝部を嵌合させることで、他の桟瓦を施工する際の桟瓦の位置決めが容易になる。よって、桟瓦の施工がより容易になる。
【0044】
また、本発明における桟瓦によれば、桟部の瓦表面に、流れ方向に傾斜した水切り溝が設けられているので、一の桟瓦の一端面と、他の桟瓦の他端面との隙間から瓦表面に流れ込んだ雨水を、桟瓦の谷部に流し込むことができる。よって、桟瓦の突条の隙間から雨水が流れ込むことによる家屋の雨漏りを防止することができる。
【0045】
また、桟部に突条が設けられることにより、桟瓦の桟部分が重くなる。よって、桟瓦の桟部の下面に面している、左隣の桟瓦の差込部から入り込む風の浮力によって、桟瓦が横方向から浮き上がることを防止することができる。

The construction of a roof tile is generally performed as follows. One roof tile is hung on the tile rail, and the back surface of the rail portion 12 of the other roof tile is overlapped on the surface of the insertion portion 14 of the other roof tile, and the other roof tile is placed on the right side of the one roof tile. Place. When this operation is repeated in the right lateral direction and the horizontal arrangement has been completed to the right end, the roof tile is placed on the tile rail on the upper level by hanging from the left to the right. In this manner, the roof tiles are arranged from the eaves side of the roof plate toward the ridge side. In addition to being hooked on the tile rail by the protrusions 20, some of the roof tiles are fixed to the tile rail using nails.
[0004]
The construction of the roof tiles as described above was dangerous because the roof tiles were blown off due to vertical and horizontal shaking caused by an earthquake and strong winds caused by typhoons. Therefore, conventionally, inventions have been made to prevent scattering of the roof tiles using various methods.
[0005]
For example, an invention (refer to Patent Document 1) that attaches a bracket to a roof tile, connects the bracket with a steel cable, and fixes the steel cable to the roof (see Patent Document 1), and locks the adjacent roof tile in the roof tile. There is an invention (see Patent Document 2, Patent Document 3, and Patent Document 4) that prevents the roof tiles from floating by devising the shape of the parts that come together.

Therefore, the rain leak of a house by rainwater flowing in from the clearance gap between the protrusions 22 of the roof tile 10 can be prevented.
[0033]
Further, as shown in FIG. 6, one end surface 22a of the ridge 22 of the roof tile 10 is inclined in the flow direction as it proceeds from the cross section 12 to the insertion section 14, so that the one end face 22a and the roof tile The rainwater that has flowed into the gap between the other end face 22 b of the roof tile 10 disposed above 10 can be poured into the valley of the roof tile 10. Therefore, since rainwater does not collect between the one end surface 22a and the other end surface 22b, providing the ridges 22 on the roof tile 10 does not cause rain leakage in the house.
[0034]
In addition, as shown in FIG. 4, the other roof tile 10 b is slid obliquely from above so that the other end surface 22 b of the other roof tile 10 b is brought into contact with the inclined one end surface 22 a of the other roof tile 10 a. Are fitted into the ridges 22 of the single roof tile 10a. Therefore, when the other roof tile 10b is hooked on the one roof tile 10a, a special member (for example, a hook metal) is not used, so that the roof tile can be easily constructed.
[0035]
Further, as shown in FIGS. 4 and 6, the protrusions 22 provided on the crosspiece 12 of the roof tile 10 appear to be continuous from the eaves toward the ridge. Therefore, when the roof tile 10 according to the present invention is arranged on the entire roof, a beautiful appearance can be exhibited like a so-called main roof made of a flat tile and a round tile.
[0036]
It should be noted that the present invention can be implemented in variously modified, modified and modified forms based on the knowledge of those skilled in the art without departing from the spirit of the present invention.

【The invention's effect】
According to the roof tile in the present invention, one end face (butt portion side) inclined of the ridge in one roof tile and the other end face (head portion) of the slope in the other roof tile arranged on the upper side of the one roof tile. And the other side of the roof tile can be prevented from being lifted by strong winds, earthquakes, or the like.
[0041]
Moreover, according to the roof tile of the present invention, the hook portion of the other roof tile disposed above the one roof tile is locked to the roof surface of the rail section of the one roof tile, so that the one roof tile is the other. It is possible to prevent a single roof tile from being lifted by a strong wind or an earthquake.
[0042]
In addition, according to the roof tile in the present invention, the portion where one end surface of one roof tile and the other end surface of the other roof tile are in contact with each other is inclined in the flow direction as it proceeds from the bridge portion toward the insertion portion. ing. Therefore, it is possible to prevent the roof tile from shifting in the direction (left direction) from the insertion portion toward the rail portion. In addition, since the bottom notch portion of the lower right rail tile contacts the head notch portion of the roof tile, the roof tile does not shift in the direction from the rail portion to the insertion portion (right direction). Therefore, the roof tile in the present invention can be prevented from shifting in both the left and right directions.
[0043]
In addition, according to the roof tile in the present invention, the other end surface of the protrusion in the other roof tile is disposed above the one roof tile in the groove (or projection) provided on one end surface of the protrusion in the one roof tile. By fitting the protrusions (or grooves) provided on the slab, the connection between the one roof tile and the other roof tile becomes stronger. Therefore, it is possible to further prevent the other roof tile heads from being lifted by a strong wind or an earthquake. In addition, by fitting the protrusions and the grooves, it is easy to position the roof tile when constructing another roof tile. Therefore, the construction of the roof tile becomes easier.
[0044]
In addition, according to the cross tile in the present invention, since the draining groove inclined in the flow direction is provided on the tile surface of the cross section, the tile is formed from the gap between one end face of one cross tile and the other end face of the other cross tile. Rainwater that has flowed into the surface can be poured into the valleys of the roof tiles. Therefore, it is possible to prevent the house from leaking rain due to rainwater flowing in through the gap between the ridges of the roof tile.
[0045]
Moreover, by providing the protrusions on the crosspieces, the crosspieces of the crosspieces become heavy. Therefore, it is possible to prevent the roof tile from being lifted from the lateral direction due to the buoyancy of the wind entering from the insertion portion of the left-hand side roof tile facing the lower surface of the rail section of the roof tile.
