特許第３１９５７４４号公報
従来から、図１３に示すように、特許第３１９５７４４号公報に示された棟構造３０が知られている。すなわち、棟芯部３８の左右に最上段の桟瓦３２が施工された後、棟芯３１を挟み両側最上段の桟瓦３２の面戸ライン３９に沿って、弾性面戸３３を接着する。さらに、前記棟芯部３８の上部に両側の弾性面戸３３を被せるようにして冠瓦３４をとめ付ける棟構造３０である。詳述すると、最上段の桟瓦３２の前記棟芯３１側が前記棟芯部と平行な桟瓦切断面３５を有し、前記棟芯３１に立設する棟芯部３８の棟芯部垂直面３６に前記桟瓦切断面３５を当接させる。さらに、前記弾性面戸３３は両面接着性の軟弾性体３７を介し、最上段の桟瓦３２の面戸ライン３９上に接着されるとともに、前記弾性面戸３３の内面が軟弾性体３７を介し、前記棟芯部垂直面３６に接着される。そのうえ、前記弾性面戸３３は冠瓦３４の内面と軟弾性体３７を介し接着され、棟部防水性能を高めるものである。
【０００３】
前記棟構造３０は、棟際の桟瓦３２と冠瓦３４、さらには棟芯部３８に前記弾性シール材を接着して、前記桟瓦と冠瓦の間に発生する隙間を塞ぎ、防水性能を向上させる利点がある。
【０００４】
【発明が解決しようとする課題】
ところが、隣接する桟瓦、すなわち陸棟部の最上部桟瓦３２の横重なり部や、寄せ棟屋根の隅棟際最上段桟瓦３２の上下段に起こる縦重なり部には、隣接する桟瓦３２同士の間に隙間が発生し、弾性面戸３３及び軟弾性体３７からなるシール材ではこの隙間を埋めることができない。また、表面形状が複雑ある屋根瓦の場合は、屋根瓦表面に密着できず接着面に隙間ができ易い上、はがれ易く防水機能を十分発揮できないという問題があった。
【０００５】
また、陸棟部と隅棟部など、棟芯部３８同士が違う角度で接合する箇所については、前記冠瓦３４同士が干渉する部分で切断し、その接合部にシーリング材を塗布接着して防水する方法を採る。しかし、そのシーリング材が外部に露出するので紫外線の影響等の長期外部環境により劣化し、亀裂等が発生する恐れがある。このとき、前記棟構造３０で施工すると、前記冠瓦３４の下側は棟芯部３８しか存在しないので、前記シーリング材が劣化して発生した亀裂から雨水が入り込むと、前記棟芯部３８の劣化を招くという問題があった。
【０００６】
そこで本発明者は、表面形状に起伏がある屋根瓦の棟部施工方法において、より防水性能や施工性を向上させるべく鋭意、研究した結果、棟際桟瓦と冠瓦の間に貼り付ける弾性シール材と棟際桟瓦との境界面にシーリング材を塗布接着すればいよいという事実を見いだし、本発明を完成した。従って、本発明の課題は、屋根面に屋根瓦を施工する際、陸棟や隅棟等の棟際の納まりにおいて、施工を簡略化するとともに、長期外部環境による劣化に起因する防水性能の低下を軽減させる棟部施工方法を提供することにある。
【０００７】
【課題を解決するための手段】
本請求項１発明は、前記の課題を解決するために、勾配屋根の棟部の最上段に施工された屋根瓦の表面尻側に、それとほぼ同形状の下面を設けた弾性シール材を、前記下面に貼り付けられた粘着材を介し前記屋根瓦の表面の桁行き方向に貼り付けるとともに、前記屋根瓦と前記弾性シール材の棟芯側の境界面にシーリング材を塗布接着するという手段を採用する。
【０００８】
前記手段を採用することで、波形瓦等のような表面に起伏の大きい屋根瓦を施工する際、瓦同士の縦重なり部や横重なり部など、前記屋根瓦と弾性体シール材の接着面に発生する隙間をシーリング材で容易に埋めることができるので、防水性能を向上できる。また、接着面に外圧がかかり接着面にはがれが生じた場合でも、前記シーリング材が境界面に塗布接着されているので、隙間が発生することなく防水性能を維持することができる。
【０００９】
さらに本請求項２発明は、前記課題をより効果的に解決するために、勾配屋根の棟部の最上段に施工された屋根瓦の表面尻側に、それとほぼ同形状の下面を設けた弾性シール材を、棟部７の棟芯に対し所定の幅をあけて両側面に前記下面に貼り付けられた粘着材を介し前記屋根瓦の表面の桁行き方向に貼り付けるとともに、前記屋根瓦と前記弾性シール材の前記棟芯側の境界面にシーリング材を塗布接着する施工方法であって、前記弾性シール材の上に前記棟芯を跨いでシート状の防水材を貼り付けるという手段を採用する。
【００１０】
前記手段を採用することにより、冠瓦とシート状の防水材とで二重防水構造を構成し、冠瓦同士の干渉部に塗布接着したシーリング材が、長期外部環境によって劣化し雨水が浸入した場合でも、冠瓦の内側に貼り付けたシート状の防水材で防水することができるので、防水性能を向上させるという効果を発揮する。
【００１１】
【発明の実施の形態】
以下、本発明の一実施例を図面に基づいて説明する。図１、図２及び図３に示すように、本発明にかかる弾性シール材１は、上面２からみて帯状であり、側面からみると下面３は使用される桟瓦の表面形状にならった凹凸のある形状が設けられたＥＰＤＭ（エチレンプロピレンジエンゴム）系発泡体である。そして、上面２からみた幅は、屋根瓦表面に取り付けられ冠瓦１２で圧縮した際、座屈しない程度の十分な幅を備えている。さらに、その下面３に設けられた凹凸は前記弾性シール材１が使用される屋根瓦５の表面形状にならった形状に屈曲し、前記屋根瓦５に貼り付けたとき隙間ができにくいようになっている。そして、その下面３にはアクリル系粘着材４が貼り付けられており、屋根瓦５の表面に前記弾性シール材１を載せて上部から軽く押さえるだけで屋根瓦５への固定が容易に可能となっている。そのうえ、前記粘着材４の上部には剥離紙が貼り付けられており、梱包や輸送時に他の部材や弾性シール材が接着しないようになっている。また、前記弾性シール材１は、長手方向にある程度の長さを設けて、一個体で棟際屋根瓦数枚分にわたって貼り付けられるようになっている。
【００１２】
また、屋根瓦５と弾性シール材１の境界面に塗布接着されるシーリング材６はブチルゴム系の建築用シーリング材である。さらに、図１０に示すようにシート状の防水材９は、長方形の平面形状をなし、貼り付けるとき、あるいは貼り付けた後に破損しない十分な厚みを備えたＥＰＤＭ系ゴムシートである。そして、その一方の平面には、ブチルゴム系粘着材が貼り付けられており、瓦同士の継ぎ部等に貼り付け、防水手段として活用できるようになっている。
【００１３】
以下においては、前述した各部材を使用した棟部７の施工方法について詳述する。図４、図５及び図６に示すように勾配屋根の棟部７において、はじめに棟芯８に沿って垂木支持金具１１を、所定の間隔をあけて両側から釘またはネジを用いてとめつける。ついで、前記垂木支持金具の上に棟垂木１０を乗せ、釘またはネジを用いて両側から固定する。そして、屋根面全体に屋根瓦５の位置決め用瓦桟木１３を、屋根瓦５の利き長さ間隔ごとにとめ付け、屋根瓦５を屋根面全体に施工する。さらに、冠瓦１２を乗せた幅より所定の幅分ひかえた位置に墨打ちし、このラインにならって弾性シール材１を、下面２側を下向きにして外側をあわせ貼り付ける。前記墨打ち作業を行うことで、前記弾性シール材を前記棟芯８に平行に貼り付けることができるので、外観よく取り付けることができる。
【００１４】
さらに、図６、図７、図８及び図９に示すように、先に貼り付けた前記弾性シール材１の棟芯８側、すなわち外面から露出しない側と屋根瓦５の境界面に沿って、シーリング材６を塗布接着する。この作業を行うことで、前記境界面に発生した隙間を埋めることができるとともに、隣接する屋根瓦５同士の間に発生する段差部において、前記弾性シール材を屋根瓦５に貼り付けると発生する隙間１４部を埋めることができる。この結果、防水性能を向上させるとともに、前記弾性シール材の接着力を強化することができる。
【００１５】
そのうえ、図１１及び図１２に示すように、棟芯８に対し所定の幅をあけて両側面に前記弾性シール材１を貼り付けた後、その上にシート状の防水材９を貼り付ける。冠瓦１２まで施工すると、前記冠瓦と弾性シール材とで二重防水構造を構成し、前記冠瓦１２とシート状の防水材９で防水することができ、防水性能を高めることができる。
【００１６】
その後、前記棟垂木１０の長手方向の中心と前記冠瓦１２の中心線をあわせ位置決めし、前記弾性シール材１を圧縮しながら釘またはネジで前記棟垂木１０に止めつける。
【００１７】
【発明の効果】
以上詳述したように本発明は、勾配屋根に屋根瓦を用いた際に、前記弾性シール材とシーリング材を使用した工法を用いることで、弾性シール材を貼り付けただけでは発生してしまう隙間を塞ぐことができるとともに、さらに前記シート状の防水材を前記弾性シール材の上部に貼り付けることでさらなる防水性能を向上させるという優れた効果を発揮する。
