Description

【０００１】
【発明の属する技術分野】
本発明は、野地板等の屋根面に葺かれる屋根パネルの設置構造に関する。
【０００２】
【従来の技術】
野地板等の屋根面に葺かれる屋根パネルの設置構造には、上段の屋根パネルの軒側と屋根面との間に差し込み空間部を形成し、この差し込み空間部に下段の屋根パネルの棟側端部を差し込んで、上段の屋根パネルと下段の屋根パネルとの間に雨水等が浸入しないように、上段の屋根パネルの軒側端部と下段の屋根パネル棟側端部とを重複させていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、例えば、屋根流れ方向に異なる種類の屋根パネルが葺かれる場合、特に、太陽電池を有する太陽電池用の屋根パネルを下段に葺きその上段に、太陽電池の機能を有さない通常の屋根パネルを葺く場合には、通常の屋根パネルに比べて太陽電池パネルの屋根流れ方向の長さが短くなる傾向があるため、上段の屋根パネルと下段の太陽電池パネルとの重複部分の重なりが短くなり、上段の屋根パネルの軒側端部と下段の太陽電池パネル棟側端部との間に浸入した雨水等が重複部分を越えて、棟側の屋根面（下段の太陽電池パネルの棟側端部よりも棟側の屋根面）に浸入してしまい、屋根面の防水性が低下する問題があった。
【０００４】
本発明は上記問題点に鑑み、上段の屋根パネルと下段の屋根パネルとの重複部分の重なりが短い場合でも、雨水等が重複部分を越えて、下段の屋根パネル棟側端部よりも棟側の屋根面に浸入しないようにして屋根面の防水性を向上させることができるようにしたものである。
【０００５】
【課題を解決するための手段】
この技術的課題を解決するための本発明の技術的手段は、上段の屋根パネル３，５の軒側と屋根面１との間に差し込み空間部３１が形成され、この差し込み空間部３１に下段の屋根パネル３，５の棟側端部が差し込まれた屋根パネルの設置構造において、上段の屋根パネル３，５の軒側端部と、差し込み空間部３１に差し込まれた下段の屋根パネル３，５の棟側端部との間に浸入した水を軒側に排出する水切り部材６０が設けられている点にある。
【０００６】
また、本発明の他の技術的手段は、水切り部材６０は、上段の屋根パネル３，５の軒側端部と差し込み空間部３１に差し込まれた下段の屋根パネル３，５の棟側端部との間に設けられた水切り片６１を有し、水切り片６１の軒側端部は、下段の屋根パネル３，５の棟側端部に連結され、水切り片６１の棟側端部は下段の屋根パネル３，５の棟側端部よりも棟側に突出されている点にある。
また、本発明の他の技術的手段は、水切り部材は６０は、下段の屋根パネル３，５の棟側端部よりも棟側の屋根面１に固定される固定部６２と、固定部６２の軒側端部から起立した起立部６３とを有し、起立部６３の上端部から軒側に水切り片６１が突出されている点にある。
【０００７】
また、本発明の他の技術的手段は、下段の屋根パネルが、太陽電池の機能と屋根瓦の機能とを併せ持つ太陽電池用の屋根パネル３で構成され、上段の屋根パネルが、太陽電池の機能を有さない通常の屋根パネル５で構成されている点にある。
【０００８】
【発明の実施の形態】
以下、本発明を図示の実施の形態に従って説明する。
図１において、屋根面１に、太陽電池の機能と屋根瓦の機能とを併せ持つ太陽電池用の屋根パネル（太陽電池パネル）３と、太陽電池の機能を有さず屋根瓦としての機能を持つ通常の屋根パネル５とが葺かれている。
なお、本実施の形態では、屋根面１の中央部側にのみ太陽電池パネル３が葺かれ、屋根面１の周辺部に通常の屋根パネル５が葺かれている。
【０００９】
通常の屋根パネル５として、例えば、金属系屋根材、セメント系硬化材やセラミックス等を一定温度で加熱養生して製造された窯業系材料により構成された平板形状の屋根瓦（例えば、（株）クボタ製のコロニアル（商品名））が採用される。
屋根パネル５は、その下面に形成された係合凸部４を屋根面１の桟木６に引っ掛けることにより（図５参照）、屋根流れ方向に位置決めして、釘又はねじ９により固定されている。桟木６は、野地板７上に、屋根流れ方向に所定間隔をおいて平行に設けられている。
【００１０】
太陽電池パネル３は、通常の屋根パネル５と同様に、野地板７の上面に敷設したアスファルトルーフィング等よりなる防水シート上に釘又はねじ９によって直接固定されている。
すなわち、図２に示すように、太陽電池パネル３は、通常の屋根パネル５と同じように野地板７にレール無しで葺き上げることができる屋根瓦としての機能を併せ持つ屋根材一体型のもので、ソーラーセルをガラスで封入してなる太陽電池１０を板金製の矩形の瓦基板１１の上面に張り付けて構成されたパネル本体１２と、このパネル本体１２の裏面側に着脱自在に接合されてその下地となるベース部材１３と、を備えている。
【００１１】
図２〜図４に示すように、瓦基板１１の棟側端部には、軒側に開口したコの字状に折り返された水返し片１４が屈曲形成され、この水返し片１４に太陽電池１０の棟側端部が嵌合されている。この水返し片１４の上側平坦部は棟側係止片１５とされ、瓦基板１１における水返し片１４よりも更に棟側の部分には、上方に開口する排水横樋１６が一体に形成されている。
一方、瓦基板１１の軒側端部には、取付片１７と折り返し片１８と軒側係止片１９とが一体に形成されている。このうち、取付片１７は瓦基板１１の軒側端部を下方に屈曲して形成され、折り返し片１８はその取付片１７の下端部を棟側に折り返して形成され、軒側係止片１９はその折り返し片１８の先端部を軒側に折り返して形成されている。
【００１２】
ベース部材１３は、パネル本体１２の踏み強度や断熱性を保つための下地材として機能するもので、軒側端部から棟側端部に向けて徐々に肉厚が薄くなる断面楔形の板状に形成された発泡樹脂よりなる。このベース部材１３の幅方向中央部の軒側には、パネル本体１２側の端子ボックス（図示せず）を収納する収納凹部２０が設けられている。
このベース部材１３の左右両側には、帯状の金属板材よりなる補強プレート２２が固定されている。この補強プレート２２の軒側端部には、野地板７及びパネル本体１２に対する固定部を構成する固定ブラケット２３が固定され、補強プレート２２の棟側端部には、パネル本体１２の棟側端部を掛止する掛止片２４が形成されると共に、下側に鉤形に屈曲した係合片２５が形成されている。
【００１３】
図３及び図４に示すように、固定ブラケット２３は、帯状の金属板材をほぼコ字形に屈曲形成してなり、屋根面１に固定される固定部２７と、固定部２７の棟側端部から起立した起立部２８と、起立部２８の上端から軒側に突出した支持部２９とを有し、固定ブラケット２３の幅方向中央部に、固定部２７、起立部２８及び支持部２９に亘って円弧状に膨出した補強リブ３０が設けられている。支持部２９と固定部２７との間に、下段側の太陽電池パネル３又は通常の屋根パネル５の棟側端部を差し込む差し込み空間部３１が形成されている。
【００１４】
固定ブラケット２３の固定部２７は野地板７に添って配置されて、釘又はねじ９によって野地板７に固定されている。支持部２９にパネル本体１２の軒側端部が載置されている。
また、固定ブラケット２３の支持部２９の前端縁部２９ａに、前記取付片１７がストッパー金具３６を介して止めねじ３７で固定されている。従って、瓦基板１１と太陽電池１０とからなるパネル本体１２は、瓦基板１１の棟側端部に形成された排水横樋１６を補強プレート２２の掛止片２４に嵌合させた状態で、瓦基板１１の軒側端部に形成された取付片１７を固定ブラケット２３の支持部の前端縁部２９ａに止めねじ３７で固定することにより、ベース部材１３に対して着脱自在に取り付けられている。
【００１５】
固定ブラケット２３の固定部２７に、係合凹部３９が、屋根面１の桟木６を避けるように上側に没入形成されている。固定ブラケット２３の係合凹部３９と起立部２８との間が、太陽電池１０の配線ケーブル４０を収納するケーブル収納部４１とされている。
固定ブラケット２３の係合凹部３９の上壁に、係止片４２が切り起こし形成されている。係止片４２は、下段側の太陽電池パネル３の係合片２５に係合され、下段側の太陽電池パネル３の軒側への移動を規制している。
【００１６】
また、取付片１７とともに固定ブラケット２３にねじ止めされる前記ストッパー金具３６は棟側に突出する爪部３６ａを有しており、この爪部３６ａに瓦基板１１の上面に接着剤等で張り付けた太陽電池１０の軒側端部を引っ掛けることにより、太陽電池１０が瓦基板１１に対して屋根流れ方向にずれるのを規制している。
図２に示すように、ベース部材１３の幅方向縁部には、金属製の排水縦樋３８が接着剤等で固定され、この排水縦樋３８の棟側端部に、前記排水横樋１６の開放端部がやや上下に離間した状態で接続されている。また、この排水縦樋３８の軒側端部は、一つ下段に位置する太陽電池パネル３の排水縦樋３８又は排水横樋１６に届く程度にまでベース部材１３の軒側端面から突出している。
【００１７】
図３及び図４に示すように、屋根流れ方向に隣接する太陽電池パネル３，３同士の接続は、固定ブラケット２３によって、上段の太陽電池パネル３の軒側と屋根面１との間に形成された差し込み空間部３１に、下段の太陽電池パネル３の棟側端部が差し込まれことによって行われ、上段の太陽電池パネル３の軒側端部と、差し込み空間部３１に差し込まれた下段の太陽電池パネル３の棟側端部との間の隙間を、閉塞部材４３により軒側から塞いでいる。
閉塞部材４３は、太陽電池パネル３の軒側端部に係合される上係合片４４と、下段の太陽電池パネル３の棟側端部に係合される下係合片４５と、前記隙間を塞ぐ閉塞壁４６とを備え、閉塞壁４６は上係合片４４と下係合片４５とを連結してている。
【００１８】
閉塞部材４３の閉塞壁４６は、棟側に向けて下降傾斜した上傾斜部４６ａと、軒側に向けて下降傾斜したした下傾斜部４６ｂとを有するようにＶ字状に屈曲されている。
閉塞部材４３の上係合片４４は閉塞壁４６の上端から棟側に突出され、下係合片４５は閉塞壁４６の下端から棟側に突出され、上係合片４４は、上段の太陽電池パネル３の軒側係止片１９に係合され、下係合片４５は、下段の太陽電池パネル３の棟側係止片１５に係合され、上係合片４４と下係合片４５とは、上段の太陽電池パネル３の軒側係止片１９と下段の太陽電池パネル３の棟側係止片１５とを、上下に挟持している。
【００１９】
図５及び図６に示すように、屋根流れ方向に隣接する太陽電池パネル３と屋根パネル５との接続は、前記屋根流れ方向に隣接する太陽電池パネル３，３同士の接続の場合と同様に、固定ブラケット２３によって、上段の太陽電池パネル３の軒側と屋根面１との間に形成された差し込み空間部３１に、下段の屋根パネル５の棟側端部が差し込まれことによって行われると共に、固定ブラケット２３の側方に設けた連結ブラケット５１を利用して行われる。また、太陽電池パネル３，３同士の接続の場合と同様に、上段の太陽電池パネル３の軒側端部と、差し込み空間部３１に差し込まれた下段の屋根パネル５の棟側端部との間の隙間を、閉塞部材４３により軒側から塞いでいる。
【００２０】
連結ブラケット５１は、図２にも示すように、上段の太陽電池パネル３のベース部材１３の前端面に固着されている。連結ブラケット５１は、帯状の金属板材をほぼコ字形に屈曲形成してなり、屋根面１に固定される固定部５２と、固定部５２の棟側端部から起立した起立部５３と、起立部５３の上端から軒側に下降傾斜するように突出された押圧部５４とを有し、押圧部５４と固定部５２との間に、下段側の太陽電池パネル３又は屋根パネル５の棟側端部を差し込む差し込み空間部３１が形成されている。固定部５２は野地板７に添って配置されて、釘又はねじ９によって野地板７に固定されている。連結ブラケット５１の固定部５２に、係合凹部５５が、屋根面１の桟木６を避けるように上側に没入形成されている。押圧部５４の先端側で、屋根パネル５の棟側端部を下方に押圧して、押圧部５４の先端側と係合凹部５５との間で、屋根パネル５の棟側端部を挟持している。
【００２１】
なお、本実施の形態の場合、屋根流れ方向に隣接する太陽電池パネル３と屋根パネル５との接続部分では、固定ブラケット２３の係合片４２を省略している。また、屋根流れ方向に隣接する太陽電池パネル３同士の接続部分では、連結ブラケット５１は省略されている。
図７及び図８に示すように、屋根流れ方向に隣接する太陽電池パネル３と屋根パネル５との（上段が屋根パネル５であり下段が太陽電池パネル３である）接続は、上段の屋根パネル５の軒側と屋根面１との間に形成された差し込み空間部３１に、下段の太陽電池パネル３の棟側端部が差し込まれことによって行われ、差し込み空間部３１には水切り部材６０が設けられている。
【００２２】
水切り部材６０は、上段の屋根パネル５の軒側端部と差し込み空間部３１に差し込まれた下段の太陽電池パネル３の棟側端部との間に設けられた水切り片６１と、下段の太陽電池パネル５の棟側端部よりも棟側の屋根面１に固定される固定部６２と、固定部６２の軒側端部から起立した起立部６３とを有しており、起立部６３の上端部から軒側に水切り片６１が突出されている。
水切り部材６０の固定部６２は、野地板７に添って配置され、釘又はねじ９によって野地板７に固定されている。
【００２３】
水切り片６１の軒側端部には、取付片６４が一体に形成されており、取付片６４は水切り片６１の軒側端部を下方に屈曲すると共に、棟側に折り返して形成されている。取付片６４を下段の太陽電池パネル３の棟側係止片１５に係合することにより、水切り片６１の軒側端部は太陽電池パネル３の軒側端部に連結されている。水切り片６１の棟端部は、下段の太陽電池パネル３の棟側端部よりも棟側に突出されている。
上記実施の形態によれば、屋根面１に太陽電池パネル３及び通常の屋根パネル５を葺く場合、太陽電池パネル３を予め組み立てておき、作業者は棟側を向いた状態で、野地板７上の桟木６に太陽電池パネル３又は屋根パネル５を係合凹部３９又は係合凸部４を桟木６に引っ掛けながら、太陽電池パネル３、屋根パネル５を棟側から順次配置し、釘又はねじ９で固定ブラケット２３の固定部２７等を野地板７に固定してゆけばよい。
【００２４】
この際に、太陽電池パネル３の棟側端部を、既に設置している上段の太陽電池パネル３の軒側の差し込み空間部３１に簡単に差し込むことができ、これにより、下段の太陽電池パネル３の棟側係止片１５を上段の太陽電池パネル３の軒側係止片１９の下方に対向させ、このようにして対向配置された両係止片１５，１９間に閉塞部材４３を軒側から外嵌することにより、閉塞部材４３の上係合片４４と下係合片４５との間で係止片１５，１９を挟持して、閉塞部材４３の閉塞壁４６で、上段の太陽電池パネル３の軒側端部と、差し込み空間部３１に差し込んだ下段の太陽電池パネル３の棟側端部との間の隙間を、軒側から簡単に塞ぐことができる。
【００２５】
従って、太陽電池パネル３を葺く場合に、棟側（屋根流れ方向上側）から軒側（同方向下側）に向かって順次葺き下げて行くことができるので、太陽電池パネル３を軒側から棟側に向かって葺き上げて行く場合に比べて施工が極めて楽になるとともに、作業者が太陽電池パネル３を踏みつけることに伴う太陽電池１０の破損や断線事故を可及的に防止することができる。
また、太陽電池パネル３を葺く場合に、従来のように屋根面１の桟木６を取り除く必要がなくなり、太陽電池パネル３の施工が楽になる。しかも、太陽電池パネル３の下面側に設けた係合凹部３９を屋根面１の桟木６に係合することにより、太陽電池パネル３を屋根流れ方向に簡単かつ確実に位置決めすることができる。
【００２６】
従って、太陽電池パネル３を他の太陽電池パネル３及び通常の屋根パネル５に対して、屋根流れ方向に正確かつ簡単に位置合わせできるようになり、この点からも、太陽電池パネル３を楽に施工することができる。また、桟木６がない場合でも、係合片２５と係止片４２とにより容易に位置決めが行えることによっても、太陽電池パネル３等を楽に施工することができる。
また、上段の太陽電池パネル３の軒側端部と、差し込み空間部３１に差し込まれた下段の太陽電池パネル３又は屋根パネル５の棟側端部との間の隙間を、閉塞部材４３によって軒側から塞ぐことにより、上段側の太陽電池パネル３と下段側の太陽電池パネル３又は屋根パネル５との接続部分から雨等が浸入しないようになし得ると共に、上段側の太陽電池パネル３と下段側の太陽電池パネル３又は屋根パネル５との接合部分に生じる段差が目立たないようにして、外観上の体裁を良くすることができる。
【００２７】
また、閉塞部材４３の閉塞壁４６が、上傾斜部４６ａと下傾斜部４６ｂとを有するようにＶ字状に屈曲されているので、屋根流れ方向に隣接する太陽電池パネル３同士の接続部分又は太陽電池パネル３と通常の屋根パネル５との接続部分に生じる段差が、比較的大きな段差であっても、閉塞壁４６のＶ字状の屈曲により段差を小さく見せて極力目立たないようにすることができ、この点からも外観上の体裁が良くなる。
さらに、閉塞壁４６が上記の如くＶ字状に屈曲されているので、上段の太陽電池パネル３の軒側端部と、差し込み空間部３１に差し込まれた下段の太陽電池パネル３又は屋根パネル５の棟側端部との間の隙間が多少変動しても、閉塞壁４６のＶ字状に屈曲した屈曲部分の弾性変形等により、その隙間の変動を吸収して、閉塞部材４３を前記隙間を確実に塞ぐことができる。また、従来のように、下段の屋根パネル３の棟側端部上に、笠木や雨押さえ部材を設ける必要がなくなり、上段の屋根パネル３，５と下段の屋根パネル３，５との接合部分の構成部材を少なくして、太陽電池パネル３及び屋根パネル５の施工を安価かつ容易になし得るようになる。
【００２８】
また、水切り部材６０の水切り片６１が上段の屋根パネル５の軒側端部と、差し込み空間部３１に差し込まれた下段の太陽電池パネル３の棟側端部との間に設けられているので、上段の屋根パネル５の軒側端部と、差し込み空間部３１に差し込まれた下段の太陽電池パネル３の棟側端部との間に浸入した雨水等が、下段の太陽電池パネル３の棟側端部（上段の屋根パネル５の軒側端部と下段の太陽電池パネル３の棟側端部とが重複している重複部分）を越えて棟側に浸入しても、水切り片６１がこの雨水を受けて、下段の太陽電池パネル５の瓦基板１１に排出させることができる。
【００２９】
したがって、上段の屋根パネル５の軒側端部と下段の太陽電池パネル３の棟側端部との重複部分が短いということによって、この重複部分を越えて雨水が棟側に浸入したとしても棟側の屋根面１（下段の太陽電池パネル３の棟側端部よりも棟側の屋根面１）に浸入することはなく、屋根面１の防水性を向上させることができる。
なお、前記実施の形態では、屋根流れ方向に隣接する上段の太陽電池パネル５の軒側と屋根面１との間に差し込み空間部３１が形成され、この差し込み空間部３１に下段の太陽電池パネル３又は通常の屋根パネル５の棟側端部が差し込まれ、この上段の太陽電池パネル３の軒側端部と、差し込み空間部３１に差し込まれた下段の太陽電池パネル３又は通常の屋根パネル５の棟側端部との間の隙間を、軒側から閉塞部材４３で塞ぐようにしているが、屋根流れ方向に隣接する屋根パネルはこのような組み合わせのものに限定されず、屋根流れ方向に隣接する上段の通常の屋根パネル５の軒側と屋根面１との間に差し込み空間部３１が形成され、この差し込み空間部３１に下段の太陽電池パネル３又は通常の屋根パネル５の棟側端部が差し込まれ、この上段の通常の屋根パネル３の軒側端部と、差し込み空間部３１に差し込まれた下段の太陽電池パネル３又は通常の屋根パネル５の棟側端部との間の隙間を、軒側から閉塞部材４３で塞ぐようにしてもよい。
【００３０】
また、前記実施の形態によれば、太陽電池パネル３の軒側に設けられた固定ブラケット２３に、屋根面１の桟木６に係合する係合凹部３９が設けられているが、係合凹部３９を設ける位置は固定ブラケット２３に限定されず、例えば太陽電池パネル３のベース部材１３の下面側に設けるようにしてもよく、要するに太陽電池パネル３の下面側に係合凹部３９を設ければよい。
