Description

【０００１】
【発明の属する技術分野】
【０００２】
本願発明は、瓦屋根の棟部構造に関するものである。
【従来の技術及び発明が解決しようとする課題】
【０００３】
図５には、従来の一般的な瓦屋根の棟部構造を示している。この従来の棟部構造では、屋根下地材（野地板）１の傾斜面上に多数枚の瓦（平瓦や桟瓦が使用されるが、以下の説明では総称して平瓦という）５，５・・を葺き、屋根下地材１の棟部１１に棟下平瓦４，４を介して棟瓦３を取付けている。
【０００４】
この図５に示す従来例では、棟瓦３は、下地材棟部１１上に取付けた木材製の棟瓦取付台２Ａに棟瓦３に形成した釘穴を通して釘６Ａを打ち込んで固定している。尚、他の棟瓦固定方法として、針金（銅線）で緊縛するものもある。又、棟瓦３の下面には、棟下平瓦４の上端部４ａを包み込むようにして棟葺土９が充填されている。
【０００５】
ところで、例えば台風時のように風雨が強いと、雨水が棟下平瓦４の上面に沿って吹き上げられて棟瓦３の側縁３ａ下面と棟下平瓦４上面との間から侵入することがある。このように、棟瓦３と棟下平瓦４との間に雨水が侵入すると、その雨水が毛細管現象により棟葺土９中に滲み込んでいき、その侵入雨水で雨漏りを引き起こすことがある。
【０００６】
又、下地材棟部１１上の棟瓦取付台２Ａは、比較的細幅で棟部１１に対する取付強度が比較的弱く、従って該棟瓦取付台２Ａに釘止めされる棟瓦３の取付強度はさほど強くないのが現状である。
【０００７】
本願発明は、上記した従来の瓦屋根棟部構造の問題点に鑑み、棟瓦を強固に固定でき且つ瓦屋根棟部から雨水が侵入してもその侵入雨水で屋根下地材（野地板等）を濡らすことがない（雨漏りしない）ようにした瓦屋根の棟部構造を提供することを目的としている。
【課題を解決するための手段】
【０００８】
本願発明は、上記課題を解決するための手段として次の構成を有している。尚、本願発明は、瓦屋根の棟部構造を対象にしている。
【０００９】
本願発明の棟部構造は、瓦屋根における水平棟部や傾斜棟部に適用できるものである。そして、この発明の棟部構造は、屋根下地材の水平棟部に、板金又はプラスチック板製で所定高さを有する棟瓦取付台と該棟瓦取付台の下部両側にそれぞれ水を受け得る樋状部とを一体形成した長尺の棟心部材を取付け、棟心部材の棟瓦取付台に、棟瓦に形成したビス穴を通してドリルビスをねじ込んで該棟瓦を固定し、棟心部材の各樋状部の端部に屋根傾斜方向に向く別の樋部材を接続する一方、樋部材の下端を下段側の瓦の瓦尻上面に載せていることを特徴としている。
【００１０】
この発明の棟部構造で使用される棟心部材が板金製の場合は、適宜幅（例えば６０〜１００cm幅）の１枚ものの長尺板金をその幅方向の適数箇所を全長に亘って折曲して、幅方向中央部に所定高さの棟瓦取付台を形成するとともに、その棟瓦取付台の下端両側にそれぞれ樋状部を形成する。又、該棟心部材がプラスチック板製の場合は、上記板金製の棟心部材と同様の形状に成型（例えば押し出し成型）する。この棟心部材は、折曲状態でかなりの保形性があり、且つ後述するようにドリルビスを容易にねじ込み得る比較的薄厚さのものが採用される。尚、この棟心部材の厚さは、特に限定するものではないが、板金製の場合は例えば０.５mm程度が適当であり、プラスチック板製の場合は例えば１〜２mm程度が適当である。
【００１１】
棟心部材の棟瓦取付台は、その上面に平面部を形成するとよい。棟瓦取付台（上面平面部）の高さは、棟部に設置される棟下平瓦の取付け高さや棟瓦の上下高さ等によって適宜に設計されるが、該棟部に各種瓦を設置したときに棟瓦の下面が棟瓦取付台の上面平面部より若干高さだけ上方に離間するように設定することが好ましい。尚、棟瓦取付台の上面平面部は、特にビス用の穴を空けなくても、ドリルビス（電動ドリルでねじ込まれる）であれば容易に穿孔して進入させることができる。
【００１２】
棟心部材の各樋状部は、棟瓦取付台の下端からそれぞれ屋根下地材の傾斜方向に適宜幅（例えば２０〜３０cm幅）だけ傾斜させた後、その各傾斜端縁を適宜高さ（例えば１〜３cm程度）だけ上向きに折曲して形成できる。
【００１３】
そして、この発明の瓦屋根の棟部構造を構築するには、まず棟心部材をその各樋状部が屋根下地材の水平棟頂部の左右に跨がる状態で設置する（このとき棟瓦取付台が水平棟頂部の直上方に位置している）。この場合、棟心部材が水平状態で設置される。又、この棟心部材は、樋状部の上端部寄り位置（棟瓦取付台に近い部分）を屋根下地材に釘打ちして固定することができる。そして、棟心部材の各樋状部の上部をそれぞれ棟下平瓦で被覆するとともに、左右の棟下平瓦に跨がって棟瓦を配置し、その棟瓦の上方から該棟瓦に形成しているビス穴を通してドリルビスを棟瓦取付台の上面にねじ込むことによって該棟瓦を固定している。
【００１４】
この発明の瓦屋根の棟部構造では、棟心部材が屋根下地材の棟部に安定姿勢で設置されており、且つその棟心部材の棟瓦取付台に棟瓦がドリルビスで固定されているので、該棟瓦の取付状態が強固になる。又、台風等の風雨の強いときには棟瓦の側縁下面と棟下平瓦上面との間から雨水が吹き込まれることがあるが、その吹き込まれた雨水が棟下平瓦の上端縁を越えてその下方に侵入しても、その侵入雨水は棟心部材の樋状部で受けられ、屋根下地材を濡らすことがない（雨漏りしない）。尚、棟瓦が割れたり、各棟瓦間に隙間ができたりすると、棟瓦下方に雨水が侵入するが、その場合も、その侵入雨水を棟心部材の樋状部で受けることができる。
【００１５】
又、この発明では、棟心部材を屋根下地材の水平棟部に設置しており、さらに棟心部材の各樋状部の端部に屋根傾斜方向に向く別の樋部材を接続し、該各樋部材の下端を下段側の瓦の瓦尻上面に載せている。
【００１６】
このようにすると、棟心部材が水平姿勢で設置されるものであっても、樋状部で受けた雨水が該樋状部の端部から流出したときに、その流出雨水を別の樋部材で瓦上面に導くことができ、樋状部に受けた雨水で屋根下地材を濡らすことがない。
【発明の効果】
【００１７】
本願発明の瓦屋根の棟部構造では、上記のように、板金又はプラスチック板製で棟瓦取付台とその下部両側にそれぞれ各樋状部とを一体形成した棟心部材を使用し、この棟心部材を屋根下地材の水平棟部に設置した状態で、棟瓦取付台に棟瓦をドリルビスで固定している。
【００１８】
このように、棟瓦取付台の両側に各樋状部を一体形成した棟心部材では、その取付状態において各樋状部が屋根下地材棟部の両側に跨がるので、該棟心部材の取付状態が安定し、且つその取付安定状態の棟心部材の棟瓦取付台に棟瓦をドリルビスで固定しているので、該棟瓦を強固に固定することができるという効果がある。尚、このように、棟瓦の取付状態が強固であると、台風等の強風時あるいは地震発生時等において、棟瓦が位置ずれしたり外れたりしない。
【００１９】
又、風雨の強いときには、棟瓦の側縁下面と棟下平瓦上面との間から雨水が吹き込まれて、該雨水が棟下平瓦上端を越えて侵入することがあり、又棟瓦が割れたり棟瓦間に隙間ができたりしたときにも雨水が侵入することがあるが、その侵入雨水は棟心部材の樋状部で受けられるので、該侵入雨水で屋根下地材を濡らすことがない（侵入雨水が雨漏りしない）という効果がある。
【００２０】
さらに、棟心部材には、棟瓦取付台と樋状部とが一体形成されているので、上記各効果（棟瓦を強固に固定できること、侵入雨水が雨漏りしないこと）を単一の棟心部材で達成できるという効果もある。
【００２１】
又、本願発明の瓦屋根の棟部構造では、棟心部材の樋状部で受けた雨水を樋状部の端部から別の樋部材を介して瓦上面に流すことができるようになっているので、棟部構造を水平棟部に適用したものであっても、比較的簡単な構成で、棟瓦下方に侵入した雨水が屋根下地材上に流れるのを防止できるという効果がある。
【発明の実施の形態】
【００２２】
図１〜図４を参照して本願実施形態の瓦屋根の棟部構造を説明する。
【００２３】
この実施形態の瓦屋根は、野地板を敷き詰めて形成した屋根下地材１の傾斜部上面を多数枚の瓦５，５・・で葺くとともに、屋根下地材１の棟部１１に、棟心部材２（後で詳述する）と棟下平瓦４，４・・と棟瓦３，３・・とを載せて構築されている。
【００２４】
符号５の瓦には、平瓦や桟瓦が使用されるが、この実施形態ではそれらを総称して平瓦という。又、図１及び図２においては、各平瓦５，５・・の側縁同士及び各棟瓦３，３・・の端縁同士は、便宜上（作図が繁雑になるため）それぞれ単に突き合わせた状態で表示しているが、実際には各平瓦５，５の側縁同士及び各棟瓦３，３の端縁同士はそれぞれ重合させて、隣接する瓦間から雨水が下方に侵入しないようにしている。尚、この実施形態では、棟瓦３の下方に直に棟下平瓦４，４・・を設置しているが、棟瓦３と棟下平瓦４との間に熨斗瓦を介設してもよい。
【００２５】
屋根下地材１の水平棟部１１には、板金又はプラスチック板製で棟瓦取付台２１と各樋状部２５，２５とを一体形成した長尺の棟心部材２が取付けられている。尚、以下の説明では、棟心部材２として板金製のもので説明する。
【００２６】
この棟心部材２は、例えば厚さが０.５mm程度で幅が６０〜１００cm程度の１枚ものの長尺板金をその幅方向の適数箇所を全長に亘って折曲して、幅方向中央部に所定高さの棟瓦取付台２１を形成するとともに、その棟瓦取付台２１の下端両側にそれぞれ樋状部２５，２５を形成している。
【００２７】
棟心部材２の棟瓦取付台２１は、左右２枚の立上げ部２３，２３の上部に適宜幅（例えば３〜５cm幅）の平面部２２を形成している。尚、棟瓦取付台２１（平面部２２）の高さは、棟部１１に設置される棟下平瓦４の取付け高さや棟瓦３の上下高さ等によって適宜に設計されるが、該棟部に各種瓦（棟下平瓦４や棟瓦３）を設置したときに棟瓦３の下面が棟瓦取付台２１の上面平面部２２より若干高さ（例えば３〜１０mm程度）だけ上方に離間するように設定される。左右２枚の各立上げ部２３，２３には、長さ方向に所定間隔をもって同位置に貫通する多数の穴２４，２４・・が形成されている。この穴２４は、棟頂部の左右に配置される各棟下平瓦４，４同士を結束するための針金（銅線）８を挿通させるためのものである。
【００２８】
棟心部材２の各樋状部２５，２５は、棟瓦取付台２１の各立上げ部２３，２３の各下端からそれぞれ屋根下地材１の傾斜方向に適宜幅（例えば２０〜３０cm幅）だけ傾斜させた後、その各傾斜板部２６，２６の各端縁を所定高さ（例えば１〜３cm）だけ上向きに折曲して形成している。従って、この各樋状部２５，２５では、棟瓦３の下方に（棟下平瓦４の上端４ａを越えて）侵入してきた雨水を傾斜板部２６で受けて下方の溝に集約させ得るようになっている。
【００２９】
尚、棟心部材２の上記各寸法は、特に限定するものではなく、必要に応じて適宜に設計変更できる。特に、棟心部材２としてプラスチック板を使用する場合は、強度面で厚さを１〜２mm程度にすることが好ましい。
【００３０】
この棟心部材２は、その各樋状部２５，２５が屋根下地材１の水平棟頂部の左右に跨がる状態（棟瓦取付台２１が棟頂部の直上方に位置する）で設置する。この場合、図１〜図４に示すように、棟心部材２は水平状態で設置される。又、この棟心部材２は、樋状部２５，２５の上端部寄り位置（棟瓦取付台２１に近い部分）を屋根下地材１に釘打ちして固定することができる。
【００３１】
棟心部材２の各樋状部２５，２５の各端部２５ａ，２５ａには、それぞれ別の樋部材７，７を接続させている。この各樋部材７，７は、棟心部材２の樋状部２５の端部２５ａから流出する雨水を受けることができ、且つ屋根傾斜方向に向けて設置している。又、この各樋部材７，７の下端７ａ，７ａは、下段側の平瓦５の瓦尻５ａ上面に載せている。このようにすると、棟心部材２が水平姿勢で設置されるものであっても、樋状部２５で受けた雨水が該樋状部の端部２５ａから流出したときに、その流出雨水を別の樋部材７で平瓦５の上面に導くことができる。
【００３２】
この実施形態では、各樋部材７，７は連結板７ｂで一体に連結している。そして、該連結板７ｂ部分を棟部１１の左右傾斜部に跨がらせ、且つ棟心部材２の端部２５ａが連結板７ｂの上に重なる状態で、各樋部材７，７を設置している。尚、各樋部材７，７は、連結板７ｂ部分を屋根下地材１に釘止めして固定することができる。
【００３３】
又、棟部１１の全長が長い場合は、図１に示すように複数の棟心部材２，２を継ぎ足して使用できる。この場合、各側の棟心部材２，２の継ぎ足し部分を若干程度離間させて、その離間部分に単一の樋部材７を設置し、該樋部材７に各側の棟心部材２，２の樋状部端部２５ａ，２５ａを両側から接続させるとよい。このようにすると、１つの樋部材７を両側の樋状部２５，２５からの受水通路として共用できる。尚、この場合、連結板７ｂ部分が各棟心部材２，２の各端部２５ａ，２５ａ間（下面側）に跨がった状態で設置していると、各棟心部材２，２の継ぎ足し部の間隔部分に雨水が侵入しても、該侵入雨水が連結板７ｂで受けられて屋根下地材１を濡らすことがない。
【００３４】
そして、棟心部材２を設置した後、その各樋状部２５，２５の上部をそれぞれ棟下平瓦４，４・・で被覆するが、その前に棟心部材２の立上げ部２３，２３の左右近傍に各側の棟下平瓦４，４の上端４ａ，４ａの高さまで棟葺土９を充填し、左右各側の棟下平瓦４，４を所定位置に配置し、該各側の棟下平瓦４，４の上端部同士を針金８で結束する。続いて、立上げ部２３，２３の左右近傍で各側の棟下平瓦４，４の上端部の上に棟葺土９を充填した後、棟瓦３を各側の棟下平瓦４，４に跨がって載せ、その棟瓦３の上方から該棟瓦３に形成しているビス穴３１を通してドリルビス６を棟瓦取付台２１の平面部２２にねじ込むことによって、該棟瓦３を固定する。尚、ドリルビス６は電動ドリルでねじ込まれるが、ドリルビス６であれば板金又はプラスチック板製の棟瓦取付台２１（平面部２２）を比較的容易に突き破ることができ、且つ相手が板金やプラスチック板であってもドリルビス６であれば抜け出すことがない。尚、図示例では、１つの棟瓦３につきビス穴３１を２箇所形成しているが、該ビス穴３１は１箇所でもよい。
【００３５】
この実施形態の棟部構造で使用される棟心部材２は、その下部の左右にそれぞれ適宜幅の樋状部２５，２５が形成されており、該各樋状部２５，２５の比較的広面積部分が屋根下地材１の棟部１１上に面接合しているので、この棟心部材２の設置姿勢が安定している。又、棟心部材２が板金製（又はプラスチック板製）であり、且つ棟瓦３を棟瓦取付台２１にドリルビス６で固定しているので、該棟瓦３の取付状態が強固になる。
【００３６】
ところで、台風等の風雨の強いときには棟瓦３の側縁３ａの下面と棟下平瓦４の上面との間から雨水が吹き込まれ、その吹き込まれた雨水が毛細管現象により棟葺土９中に滲み込むことがある。又、棟瓦３が割れたり、あるいは棟瓦３が位置ずれして棟瓦間の隙間ができたりすると、棟瓦３の上面側からも雨水が侵入し、その侵入雨水が棟葺土９中に滲み込む。そして、該棟葺土９中に多量の水を含むと、その水の一部が棟下平瓦４の下方に侵入することがある。ところが、この実施形態の棟部構造では、その侵入雨水は棟心部材２の樋状部２５，２５で受けられ、該樋状部２５の端部２５ａから樋部材７に流れ、さらに樋部材７の下端７ａから平瓦５の上面に導かれる。従って、瓦屋根の棟部から侵入した雨水で屋根下地材１を濡らすことがない。

BACKGROUND OF THE INVENTION
[0002]
The present invention relates to a ridge structure of a tile roof.
[Prior art and problems to be solved by the invention]
[0003]
FIG. 5 shows a conventional ridge structure of a tile roof. In this conventional ridge structure, a large number of tiles (flat tiles and pier tiles are used on the inclined surface of the roof base material (field plate) 1, but in the following description are collectively referred to as flat tiles) 5, 5 The roof tile 3 is attached to the ridge 11 of the roof base material 1 via the ridge bottom flat tiles 4 and 4.
[0004]
In the conventional example shown in FIG. 5, the ridge tile 3 is fixed by driving a nail 6 </ b> A through a nail hole formed in the ridge tile 3 to a wooden ridge tile mount 2 </ b> A mounted on the base material ridge portion 11. In addition, as another ridge tile fixing method, there is a method of binding with a wire (copper wire). Moreover, the lower surface of the ridge tile 3 is filled with ridge soil 9 so as to wrap the upper end portion 4a of the ridge lower flat tile 4.
[0005]
By the way, when the wind and rain are strong, for example, during a typhoon, rainwater may be blown up along the upper surface of the ridge roof tile 4 and may enter from between the lower surface of the side edge 3a of the ridge roof tile 3 and the upper surface of the ridge roof tile 4. As described above, when rainwater enters between the ridge tile 3 and the ridge bottom flat tile 4, the rainwater permeates into the ridge soil 9 due to a capillary phenomenon, and the leaked rainwater may cause rain leakage.
[0006]
Further, the roof tile mount 2A on the base material ridge 11 is relatively narrow and has a relatively low mounting strength with respect to the ridge 11, so that the mounting strength of the roof tile 3 secured to the roof tile mount 2A is so strong. There is no current situation.
[0007]
In view of the problems of the conventional tile roof ridge structure described above, the present invention can firmly fix the ridge tile, and even if rainwater intrudes from the tile roof ridge, the roof base material (field plate etc.) The object of the present invention is to provide a tiled roof structure that does not get wet (does not leak).
[Means for Solving the Problems]
[0008]
The present invention has the following configuration as means for solving the above problems. The present invention is directed to a ridge structure of a tile roof.
[0009]
The ridge structure of the present invention can be applied to a horizontal ridge or an inclined ridge in a tiled roof. And the ridge part structure of this invention is a bowl-shaped part which can receive water on the horizontal ridge part of the roof base material, the ridge tile mounting base made of sheet metal or plastic plate, and the lower side of the ridge tile mounting base, respectively. Is attached to the roof tile mounting base of the roof core member by screwing a drill screw through a screw hole formed in the roof tile to fix the roof tile. While another heel member facing the roof inclination direction is connected to the portion, the lower end of the heel member is placed on the top surface of the bottom tile of the lower tile.
[0010]
In the case where the core member used in the ridge structure of the present invention is made of sheet metal, an appropriate length (for example, 60 to 100 cm width) of a single long sheet metal is folded over the entire length of an appropriate number of locations in the width direction. It bends to form a roof tile mount with a predetermined height at the center in the width direction, and to form hook-shaped portions on both sides of the lower end of the roof tile mount. When the ridge member is made of a plastic plate, it is molded (for example, extruded) into the same shape as the ridge member made of sheet metal. The wing core member has a considerably thin shape in a bent state, and has a relatively thin thickness capable of easily screwing a drill screw as described later. The thickness of the building core member is not particularly limited. For example, about 0.5 mm is appropriate for a sheet metal, and about 1-2 mm is appropriate for a plastic sheet.
[0011]
The roof tile mounting base of the roof center member may be formed with a flat portion on the upper surface thereof. The height of the roof tile mounting base (upper surface flat part) is designed as appropriate depending on the height of the roof tile roof tile installed in the tower and the height of the roof tile, etc. When various tiles are installed in the tower In addition, it is preferable that the lower surface of the ridge tile is set so as to be spaced apart from the upper surface plane portion of the ridge tile mount by a slight height. In addition, even if it does not make the hole for screws especially, the upper surface plane part of the roof tile mounting base can be easily drilled and entered if it is a drill screw (screwed with an electric drill).
[0012]
Each ridge-shaped part of the wing center member is inclined by an appropriate width (for example, 20 to 30 cm width) in the inclination direction of the roof base material from the lower end of the ridge tile mounting base, and then each inclined edge is appropriately height (for example, 1 to 3 cm) and bent upward.
[0013]
And in order to construct the ridge structure of the tile roof according to the present invention, first, the ridge center member is installed in a state where each hook-shaped portion straddles the left and right of the horizontal ridge top of the roof base material (at this time, the ridge tile attachment) The platform is located directly above the top of the horizontal building). In this case, the wing center member is installed in a horizontal state. Moreover, this ridge center member can nail and fix the position near the upper end part of the bowl-shaped part (portion close to the ridge tile mounting base) to the roof base material. Then, the upper part of each bowl-shaped portion of the ridge core member is covered with the ridge bottom flat tiles, and the ridge tiles are arranged over the left and right ridge bottom flat tiles, and the screws formed on the ridge tiles from above the ridge tiles. The roof tile is fixed by screwing a drill screw through the hole into the upper surface of the roof tile mount.
[0014]
In the ridge structure of the tile roof according to the present invention, the ridge member is installed in a stable posture on the ridge portion of the roof base material, and the ridge tile is fixed to the ridge tile mount of the ridge member with a drill screw. The mounting state of the roof tile becomes strong. In addition, when there is strong wind and rain such as typhoon, rainwater may be blown from between the lower side edge of the ridge tile and the upper surface of the lower flat roof tile. Even if it invades, the intruding rainwater is received by the bowl-shaped part of the building core member and does not wet the roof base material (does not leak). If the roof tiles are cracked or if there is a gap between the roof tiles, rainwater enters the bottom of the roof tiles. In this case, the rainwater can be received by the bowl-shaped portion of the building center member.
[0015]
In the present invention, the ridge member is installed in the horizontal ridge portion of the roof base material, and another ridge member facing the roof inclination direction is connected to the end of each ridge portion of the ridge member, The lower end of each saddle member is placed on the top surface of the bottom tile.
[0016]
In this way, even when the wing center member is installed in a horizontal posture, when rainwater received by the bowl-shaped portion flows out from the end of the bowl-shaped portion, the spilled rainwater is separated into another bowl member. It can be led to the top surface of the tile, and the roof base material is not wetted by the rainwater received in the bowl-shaped part.
【The invention's effect】
[0017]
In the ridge structure of the tile roof according to the present invention, as described above, a ridge core member made of sheet metal or plastic plate and integrally formed with each ridge-shaped portion on both sides of the ridge tile mounting base is used. The roof tile is fixed to the roof tile mount with a drill screw in a state where the member is installed in the horizontal tower of the roof base material.
[0018]
In this way, in the building core member in which each bowl-shaped part is integrally formed on both sides of the roof tile mounting base, each bowl-shaped part straddles both sides of the roof base material building part in the mounting state. Since the mounting state is stable, and the ridge tile is fixed to the ridge tile mounting base of the ridge center member in the stable mounting state with a drill screw, there is an effect that the ridge tile can be firmly fixed. In addition, if the mounting state of the roof tile is strong as described above, the roof tile will not be displaced or detached when a strong wind such as a typhoon or an earthquake occurs.
[0019]
Also, when wind and rain are strong, rainwater may be blown in between the lower side edge of the ridge tile and the upper surface of the ridge bottom flat tile, and the rainwater may invade beyond the top edge of the ridge bottom flat tile. Even when there is a gap in the rainwater, rainwater may intrude. However, since the intrusion rainwater is received by the bowl-shaped part of the building core member, the roof base material is not wetted by the intrusion rainwater (the intrusion rainwater It does not leak).
[0020]
In addition, since the roof tile mounting base and the bowl-shaped part are integrally formed on the building core member, the above-mentioned effects (that the building roof tile can be firmly fixed and that intrusion rainwater does not leak) can be achieved with a single building core member. There is also an effect that can be achieved.
[0021]
Moreover, in the ridge structure of the tile roof of the present invention, rainwater received by the ridge portion of the ridge center member can flow from the end of the ridge portion to the tile upper surface via another ridge member. Therefore, even if the ridge structure is applied to the horizontal ridge, there is an effect that it is possible to prevent rainwater that has entered the lower part of the ridge tile from flowing on the roof base material with a relatively simple configuration.
DETAILED DESCRIPTION OF THE INVENTION
[0022]
With reference to FIGS. 1-4, the ridge part structure of the tile roof of this embodiment is demonstrated.
[0023]
In the tile roof of this embodiment, the upper surface of the inclined portion of the roof base material 1 formed by laying the ground plate is spread with a large number of tiles 5, 5,. It is constructed by placing the member 2 (which will be described later in detail), the ridge roof tiles 4, 4... And the ridge roof tiles 3, 3.
[0024]
A flat roof tile or a roof tile is used as the roof tile of reference numeral 5, but in this embodiment, they are collectively referred to as a flat roof tile. 1 and 2, the side edges of the flat roof tiles 5, 5... And the end edges of the respective roof tiles 3, 3... Are simply in contact with each other for convenience (because drawing is complicated). In fact, the side edges of the flat roof tiles 5 and 5 and the edge edges of the roof tiles 3 and 3 are superposed to prevent rainwater from entering between the adjacent roof tiles. Yes. In this embodiment, the ridge bottom flat tiles 4, 4... Are installed directly below the ridge tile 3. However, a funnel tile may be interposed between the ridge tile 3 and the ridge bottom flat tile 4.
[0025]
A long ridge center member 2 made of sheet metal or plastic plate and integrally formed with a ridge tile mounting base 21 and hook-shaped portions 25 and 25 is attached to the horizontal ridge portion 11 of the roof base material 1. In the following description, the building core member 2 will be described as being made of sheet metal.
[0026]
The center member 2 is formed by bending a single sheet metal sheet having a thickness of about 0.5 mm and a width of about 60 to 100 cm over the entire length of an appropriate number of portions in the width direction. A roof tile mounting base 21 having a predetermined height is formed in each part, and hook-shaped parts 25 and 25 are formed on both sides of the lower end of the roof tile mounting base 21, respectively.
[0027]
The roof tile mounting base 21 of the roof core member 2 is formed with a flat portion 22 having an appropriate width (for example, 3 to 5 cm width) above the two right and left rising portions 23 and 23. The height of the roof tile mounting base 21 (plane portion 22) is appropriately designed according to the mounting height of the bottom roof tile 4 installed in the tower 11, the vertical height of the roof tile 3, and the like. When various roof tiles (the roof bottom tile 4 and the roof tile 3) are installed, the bottom surface of the roof tile 3 is set to be spaced apart from the top surface flat portion 22 of the roof tile mounting base 21 by a slight height (for example, about 3 to 10 mm). The A plurality of holes 24, 24... Penetrating at the same position at predetermined intervals in the length direction are formed in the two right and left rising portions 23, 23. The hole 24 is for inserting a wire (copper wire) 8 for bundling the flat roof tiles 4 and 4 arranged on the left and right of the ridge top.
[0028]
Each bowl-shaped part 25, 25 of the ridge core member 2 is inclined by an appropriate width (for example, 20 to 30 cm width) from the lower end of each rising part 23, 23 of the ridge tile mount 21 in the inclination direction of the roof base material 1 respectively. Then, the respective edges of the inclined plate portions 26, 26 are bent upward by a predetermined height (for example, 1 to 3 cm). Accordingly, in each of the bowl-shaped portions 25, 25, rainwater that has entered below the roof tile 3 (beyond the upper end 4a of the bottom roof tile 4) can be received by the inclined plate portion 26 and concentrated in the lower groove. It has become.
[0029]
In addition, said each dimension of the ridge center member 2 is not specifically limited, A design change can be suitably carried out as needed. In particular, when a plastic plate is used as the wing core member 2, it is preferable to make the thickness about 1-2 mm in terms of strength.
[0030]
The ridge center member 2 is installed in a state in which the bowl-shaped portions 25, 25 straddle the left and right of the horizontal ridge top portion of the roof base material 1 (the ridge tile mounting base 21 is located immediately above the ridge top portion). In this case, as shown in FIGS. 1 to 4, the core member 2 is installed in a horizontal state. Further, the ridge center member 2 can be fixed by nailing the position close to the upper end portions of the bowl-shaped portions 25, 25 (portion close to the ridge tile mounting base 21) to the roof base material 1.
[0031]
Separate flange members 7 and 7 are connected to the end portions 25a and 25a of the flange portions 25 and 25 of the wing center member 2, respectively. Each of the eaves members 7, 7 can receive rainwater flowing out from the end portion 25 a of the eaves-like portion 25 of the building core member 2, and is installed toward the roof inclination direction. The lower ends 7a and 7a of the eaves members 7 and 7 are placed on the upper surface of the tile bottom 5a of the flat roof tile 5 on the lower side. In this way, even if the wing core member 2 is installed in a horizontal posture, when the rainwater received by the bowl-shaped portion 25 flows out from the end portion 25a of the bowl-shaped portion, the drained rainwater is separated. It is possible to guide to the upper surface of the flat roof tile 5 with the eaves member 7.
[0032]
In this embodiment, the flange members 7 and 7 are integrally connected by a connecting plate 7b. And each saddle member 7 and 7 is installed in the state where this connecting plate 7b part is straddled on the right-and-left inclined part of the ridge part 11, and the edge part 25a of the ridge core member 2 overlaps on the connecting plate 7b. Yes. Each of the eaves members 7 and 7 can be fixed by nailing the connecting plate 7b portion to the roof base material 1.
[0033]
Further, when the total length of the ridge portion 11 is long, a plurality of ridge center members 2 and 2 can be added and used as shown in FIG. In this case, the added portions of the wing core members 2 and 2 on each side are slightly separated from each other, and a single flange member 7 is installed in the separated portion, and the ridge core members 2 and 2 on each side are installed in the flange member 7. It is preferable to connect the flange-shaped end portions 25a, 25a from both sides. If it does in this way, the one collar member 7 can be shared as a water-receiving channel | path from the collar-like parts 25 and 25 of both sides. In this case, if the connecting plate 7b portion is installed in a state straddling between the end portions 25a, 25a (lower surface side) of each of the core members 2, 2, each of the core members 2, 2 Even if rainwater enters the space between the added portions, the intruding rainwater is not received by the connecting plate 7b and wets the roof base material 1.
[0034]
Then, after the building core member 2 is installed, the upper portions of the bowl-like portions 25, 25 are respectively covered with the building lower flat roof tiles 4, 4,... Is filled with ridge clay 9 up to the height of the upper ends 4a and 4a of the ridge floor tiles 4 and 4 on each side, and the ridge floor tiles 4 and 4 on the left and right sides are arranged at predetermined positions. The upper ends of the flat roof tiles 4, 4 are bound with a wire 8. Subsequently, the ridge tile 9 is filled on the upper ends of the ridge bottom flat tiles 4 and 4 on each side in the vicinity of the right and left of the rising portions 23 and 23, and then the ridge tile 3 is turned into the ridge bottom flat tiles 4 and 4 on each side. The building tile 3 is fixed by screwing the drill screw 6 into the flat portion 22 of the building tile mounting base 21 through the screw hole 31 formed in the building tile 3 from above the building tile 3. The drill screw 6 is screwed with an electric drill. However, if the drill screw 6 is used, the roof tile mounting base 21 (plane portion 22) made of sheet metal or plastic plate can be pierced relatively easily, and the other party is made of sheet metal or plastic plate. Even if there is a drill screw 6, it will not come out. In the illustrated example, two screw holes 31 are formed per one roof tile 3, but the screw holes 31 may be provided at one location.
[0035]
In the ridge member 2 used in the ridge structure of this embodiment, bowl-shaped parts 25, 25 having appropriate widths are formed on the left and right sides of the lower part, respectively. Since the area portion is surface-bonded onto the ridge portion 11 of the roof base material 1, the installation posture of the ridge center member 2 is stable. In addition, since the building core member 2 is made of sheet metal (or plastic plate) and the building tile 3 is fixed to the building tile mounting base 21 with the drill screw 6, the mounting state of the building tile 3 becomes strong.
[0036]
By the way, when strong wind and rain such as typhoon, rainwater is blown from between the lower surface of the side edge 3a of the roof tile 3 and the upper surface of the flat roof tile 4, and the blown rainwater soaks into the ridge soil 9 by capillary action. Sometimes. Further, when the ridge tile 3 is cracked or the ridge tile 3 is displaced and a gap is formed between the ridge tiles, rainwater enters from the upper surface side of the ridge tile 3 and the intruded rainwater permeates into the ridge soil 9. And if a large amount of water is contained in the ridge soil 9, a part of the water may invade below the ridge floor tile 4. However, in the ridge structure of this embodiment, the intrusion rainwater is received by the ridges 25, 25 of the ridge core member 2, flows from the end 25 a of the ridge 25 to the ridge member 7, and further the ridge member 7. Is guided to the upper surface of the flat roof tile 5 from the lower end 7a. Therefore, the roof base material 1 is not wetted by rainwater that has entered from the tile roof ridge.
