Description

【０００１】
【発明の属する技術分野】
本発明は、太陽光発電の主体となる平盤形態をした太陽電池パネル及び太陽電池パネルにより構成する家屋の屋根構造に関するものである。
【０００２】
【従来の技術】
太陽光発電に用いられる太陽電池パネルの多くは、電気的に接続した複数の太陽電池セルを、表面保護基板と裏面保護材との間に挟持し、表面保護基板と裏面保護材との間に充填材層を形成して方形盤状とした基盤の周辺部にアルミ製のフレームを装着した構成が採られている。フレームは基盤の端面を嵌込む溝を有する断面形状のアルミの押出し成形材で構成され、端部からの水分や水蒸気等の侵入を防止するためにブチルゴムやシリコンゴム等の粘弾性のある防水材を介して基盤の端面に溝を使って嵌め装着されている。このような太陽電池パネルは、屋根上等に架台を介して設置されることが多いが、太陽電池パネルそのもので家屋の屋根構造を構成することもある。
【０００３】
太陽電池パネルによる屋根構造は、例えば特開平５―２８０１６８号公報に示されているような構成が採られてきた。即ち、図１３，１４に示すように受面４０が棟側から軒側に向かって階段状に構成された縦受け枠４１が棟側から軒側に向かって複数列屋根面４２に固定される。これに妻側に向けて横受け枠４３が配置され、太陽電池パネル４４が受面４０に端縁部が重なるように階段状に固定される。重ね部の下側の太陽電池パネル４４の棟側端縁が嵌合する横受け枠４３上に、上側の太陽電池パネル４４の軒側端縁が載置され、この上側の太陽電池パネル４４と横受け枠４３とがコの字状のクリップで合わせ状態に挟持される。中間の縦受け枠４１はチャンネル状に構成され、太陽電池パネル４４同士の合わせ部から侵入する雨水がチャンネルにより軒側へ排水される。妻側の端の縦受け枠４１は屋根面４２側の端縁が曲げ込まれ、妻側列の太陽電池パネル４４の端縁から流下する雨水が軒側に排水される。
【０００４】
各太陽電池パネルから引出される出力電圧を取出すための正負のリード線の配線については、配線用ダクトを併設してこの配線用ダクト内に収めるか、特開平５―１６７０９６号公報に示され、図１５によっても示すように基盤４５を保持する架台に配線用ダクト４６を一体に構成し、この配線用ダクト４６内においてリード線４７を配線している。配線用ダクト４６は上部が開放したチャンネル構造が採られ、結線を行った後に開放部が蓋４８により水密を保持した状態に塞がれる。この屋根構造では、組立て及び配線に係る作業が全て表面側から行うことができ、施工し易く作業性も良い。
【０００５】
【発明が解決しようとする課題】
上記のような太陽電池パネル４４においては、雨水に対する確りした排水構造がないため、太陽電池パネル４４で屋根構造を構成する場合には、上述したような排水構造を持つ架台状の構造体を屋根面４２上に構成しなければならず、施工に手間がかかるうえ費用も嵩むといった問題点がある。また、従来の太陽電池パネルによる屋根構造では、リード線４７を結線し配線を完了した後に配線用ダクト４６に水密保持処置を施して蓋４８をしなければならず、全て表面側から作業できるとはいえ、施工には随分煩雑な作業を要することになる。
【０００６】
本発明は、係る従来の問題点を解決するためになされたものであって、その課題とするところは、配線作業が容易で施工性の良い太陽電池パネルを得ることであり、その太陽電池パネルの排水性の向上を図り、屋根構造の構成要素として好適な太陽電池パネルを開発することであり、施工性が良く手間のかからない構成の簡素な太陽電池パネルによる屋根構造を得ることであり、その屋根構造の電気的な安全性能の向上を推進することである。

【００１６】
【発明の実施の形態】
実施の形態１．
図１〜図１０によって示す本実施の形態は、太陽光発電の主体となる平盤形態をした太陽電池パネル１及びその太陽電池パネル１により構成する家屋の屋根構造２に関するものである。まず、太陽電池パネル１の構成を図１〜図６を中心として説明し、次に屋根構造２を図７〜図１０に基づいて説明することにする。本実施の形態の太陽電池パネル１は、図１に示すように方形の平板態に構成された光発電機能体である基盤３の周辺にアルミ製のフレーム４を装着した構成である。基盤３は、ダブ線により電気的に直列接続した複数の太陽電池セルを、充填材層を形成する透明加熱融着剤のシートに挟んで、これを表面保護基板と耐候性フィルム等の裏面保護材との間に挟持して、真空引きしながら加熱して方形盤状のパネルとして構成されている。基盤３の背面には出力端子箱３０が図９に示すように設けられ、この出力端子箱３０から出力電圧を取出すための正側のリード線３１と負側のリード線３２がそれぞれ引出されている。正側のリード線３１の端にはプラグを有する雌側のコネクタ３３が接続され、負側のリード線３２の端にはピンを有する雄側のコネクタ３４が接続されている。
【００１７】
フレーム４は、斜めの設置状態で上側となる上側フレーム５と、下側となる下側フレーム６と、左右の縦フレーム７，８との組合わせによる方形の枠構造体として構成されている。左右の縦フレーム７，８の一方（図１の左側７）は、図４に示すように内側面の上部が基盤係合部として長手方向に開放した四角筒の第１の樋構造としての内樋９を備えている。内樋９は基盤係合部に係合した基盤３の側辺縁の背面に沿って上下方向に連続し、その上下端は開放し、その下端側底部は下面が凹状に削られ、その部分に通水孔１０が形成されている（図１０参照）。この縦フレーム７には内樋９の下方に内樋９に沿って連続し上下端側が開放した第２の樋構造としての下樋１１と、横方向に隣設させる他の太陽電池パネル１の縦フレーム８を突合わせるための四角筒状の係合部１２がそれぞれ一体に図４に示すように形成されている。
【００１８】
下樋１１は、両端縁が上側に曲げられた板状に構成されていて、内樋９の下部から垂直方向に延びる連結部１３により内樋９の下方に受皿状の樋を形成し、その上側端は延出部１４として内樋９より長く延出している（図１参照）。連結部１３は下樋１１を実質的に左右に分断していて、連結部１３より内側に張出す下樋１１の内端縁は内樋９の内側面よりさらに若干内側に入り込んでいる。また、連結部１３より外側に張出す下樋１１の外端縁は、横方向に隣設させる他の太陽電池パネル１の縦フレーム８の投影平面より大きく外方にフランジ状に延出している。係合部１２は、内樋９の外側に一側面を共有する形態に形成され、内樋９と係合部１２の直下に下樋１１が位置している。
【００１９】
左右の縦フレーム７，８の他方（図１の右側８）は、図５に示すように断面略Ｊ字型の筒体に形成され、上面内側面の上端部の間が基盤係合部１５として長手方向に開放している。この縦フレーム８の基盤係合部１５に続く画成部分は、その基盤係合部１５に係合した基盤３の側辺縁下部に沿って上下方向に連続する上下端の開放した第３の樋構造１６となっていて、その下端側底部には通水孔１７が形成されている。この縦フレーム８の外側部は内樋９及び下樋１１を備えた縦フレーム７の係合部１２に胴突き状態に係合させることができるようになっている。
【００２０】
上側フレーム５は図２及び図６に示すように断面略Ｅ字状に形成されていて、上側の角筒部が他の太陽電池パネル１の縦フレーム７の下端部の係合が可能なコ状の係合部１８として横方向に連続している。係合部１８の下側のフランジ１９の端縁には立上りが形成され、係合部１８が縦フレーム７の下樋１１と略直交方向に交差する横樋構造２０となっている。係合部１８の下方から外方へ略水平に張出したフランジ１９は、端縁に立上りが形成された樋状の構成で、縦フレーム７の下樋１１の延出部１４が固定される。横樋構造２０は底面となるフランジ２１と内側面となるウェブ部２２により構成され、ウェブ部２２には通水孔２３が横向きに形成されている。フランジ１９とこれに続く略垂直の内壁をなすウェブ部２２とにより各リード線３１，３２を配線し結線する配線固定部３５が構成されている。二本のリード線３１，３２はウェブ部２２に開けられた挿通孔から配線固定部３５に引出されている。基盤３の上側端縁は係合部１８のウェブ部２２の略中央から内側に張出した受けフランジ２４により受承される。下側フレーム６は平板部２５の内側に基盤３の下端縁を受ける受部２６が張出した簡単な構成となっている（図１０参照）。
【００２１】
このようにこの太陽電池パネル１には、上側フレーム５に横方向に連続する横樋構造２０があり、縦フレーム７，８の一方７には縦方向に連続する内樋９と下樋１１が、他方の縦フレーム８には縦方向に第３の樋構造１６がある。横樋構造２０は横方向に隣接する太陽電池パネル１同士の上側フレーム５の合わせ部分から侵入する雨水を受容し、ウェブ部２２に形成された通水孔２３により縦樋である内樋９に流下する。また、横樋構造２０のフランジ２１の両端の突合わせ部の隙間から漏れる雨水は、縦フレーム７の下樋１１と第３の樋構造１６により回収される。雨水の挙動は複雑であり、勾配のみで決まるものではなく、外風の作用や凝集力も雨水の動きに影響を及ぼすが、横方向と縦方向の樋構造によりあらゆる方向からの雨水の侵入に対処することができる。縦方向の樋は内樋９にさらにこれを受ける下樋１１があるので、雨水の処理はほぼ万全となる。従って、設置する場合、特別な樋設備を設ける必要がなく、直接家屋の屋根の野地板２７に固定して取付けることもできる。
【００２２】
太陽電池パネル相互の電気的な接続は、外部に開放した配線固定部３５においてリード線３２の雄側のコネクタ３４を他の太陽電池パネル１のリード線３１の雌側のコネクタ３３に接続することにより行われ、結線部もリード線３１，３２もフランジ１９上に図６に示すように配設され配線固定部３５に収められる。この作業は外部から容易に行うことができ、上側フレーム５に上側に隣接する太陽電池パネル１の下部縁が上側に重ね合わされることにより、配線固定部３５は覆われ、特別な蓋を設ける必要はなく、横樋構造２０が上部に位置するため水密保持部材も要しない。また、配線固定部３５の内側にはウェブ部２２があるため、コネクタ結合部等の発熱により万一当該部が焼けるようなことがあっても延焼は回避されることになる。
【００２３】
次に上述した構成の太陽電池パネル１によって構成する家屋の屋根構造２について説明する。ここでは、説明上、上側フレーム５を棟側フレームに、下側フレーム６を軒側フレームにそれぞれ言い換えることにする。またここで言う棟側とは設置状態での上側と同義であり、軒側とは設置状態での下側と同義である。この屋根構造２は、図７，８，９，１０に示すように太陽電池パネル１を屋根の野地板２７上に軒側から棟側へ列状に複数列並べて構成されている。野地板２７には棟側から軒側に向かって下り勾配が付けられていて、この上に棟側の太陽電池パネル１の軒側の端縁が軒側の太陽電池パネル１の棟側フレーム５の上に重なるように順次配列され、それぞれ野地板２７上にネジにより固定されている。
【００２４】
太陽電池パネル１による屋根構造２と一般の屋根構造２Ａとの境界があるような場合には、図７，８に示すように境界部に樋部材２８を縦方向に設け、一般の屋根構造２Ａ側の屋根材２９を樋部材２８にオーバーラップさせ、樋部材２８側に第３の樋構造１６を持つ縦フレーム８が向くように配列させて太陽電池パネル１による屋根構造２が構成される。棟側の太陽電池パネル１の縦フレーム７の下樋１１は軒側の太陽電池パネル１の棟側フレーム５の係合部１８に嵌め合わされ、内樋９は軒側の太陽電池パネル１の棟側フレーム５の上に重ねられて設置される（図９，１０参照）。このような配列が妻方向に複数列並べられて太陽電池パネル１による屋根構造２が構成される。妻側についての太陽電池パネル１相互は、内樋９と下樋１１のある縦フレーム７に隣接する第３の樋構造１６を有する縦フレーム８を係合部１２への突合わせ係合により接合される。この接合部分と第３の樋構造１６は下樋１１の外側へ張出した部分により受けられる。
【００２５】
妻方向に隣接する太陽電池パネル１相互の電気的な接続は、外部に開放した配線固定部３５においてリード線３２の雄側のコネクタ３４を隣接する太陽電池パネル１のリード線３１の雌側のコネクタ３３に接続し、リード線３１の雌側のコネクタ３３を隣接する他の太陽電池パネル１のリード線３２の雄側のコネクタ３４に接続することにより行われる（図１０参照）。このとき、リード線３１，３２のコネクタ接続部は、図９に示すように各太陽電池パネル１の配線固定部３５についてそれぞれ一つずつが配置される。この配線構成を採ることにより二本のリード線３１，３２が接触することがなくコネクタ接続部も一つずつとなるので、コネクタ接続部等の発熱により万一当該部が焼けるようなことがあっても延焼についてはこれを防止することができる。
【００２６】
こうした構造の太陽電池パネル１による屋根構造２において、棟側の太陽電池パネル１の内樋９に侵入した雨水は内樋９を流下していき、その下端側底部の下面が削られた部分に開設されている通水孔１０から軒側の太陽電池パネル１の表面に流下し、順次太陽電池パネル１の表面を流下して軒側端において排水される（第１の雨水流路）。下樋１１に侵入した雨水は下樋１１を流下してその下端から軒側の太陽電池パネル１の棟側フレーム５に形成された横樋構造２０に流下し、さらに横樋構造２０の通水孔２３を経て軒側の太陽電池パネル１の縦フレーム７の内樋９に流下していく（第２の雨水流路）。
【００２７】
横樋構造２０に流入した雨水の一部は、突合わせ部分の隙間から軒側の太陽電池パネル１の縦フレーム７，８における下樋１１の延出部１４及び第３の樋構造１６に回収されて流下していく（第３の雨水流路）。軒側の太陽電池パネル１の下樋１１に分流した雨水はさらにそれより軒側の太陽電池パネル１の横樋構造２０において前述したように順次分流して流下していく。また、軒側の太陽電池パネル１の内樋９に分流した雨水は、それより軒側の太陽電池パネル１の表面に流下して前述した第１の雨水流路を経て順次太陽電池パネル１の表面を流下して軒側端において排水される。
【００２８】
縦フレーム８の第３の樋構造１６に侵入した雨水は、通水孔１７で連絡した各縦フレーム８を流下して軒先端において排水される（第４の雨水流路）。棟側フレーム５の横樋構造２０は妻方向に隣接する太陽電池パネル１同士の棟側フレーム５の合わせ部分から侵入する雨水を受容し、ウェブ部２２に形成された通水孔２３により縦樋である内樋９と、第３の樋構造１６とに分流して流下させるための構造である。
【００２９】
このようにこの太陽電池パネル１による屋根構造２は、太陽電池パネル１に縦方向に３列、横方向に１列の排水構造としての樋構造が備えられ、第１〜第４の雨水流路が構成されているため、特別に排水構造を野地板２７上に構成しなくても屋根構造２を施工することができ、施工の手間も費用も軽減する。また各列について縦方向一列の樋部材で排水する屋根構造に比べ、下樋１１から内樋９、基盤３表面に排水していく構造のため樋の容量も小さく設定でき、屋根の平面積をより有効に利用することができる。さらに横樋構造２０の通水孔２３により軒側に向かって順次分流する雨水流路が構成されているため、軒側に行くほど処理雨水が増量していくようなこともなく、円滑に雨水の排水処理ができる。
【００３０】
実施の形態２．
図１１，図１２に示す本実施の形態は、実施の形態１で示した太陽電池パネル１に更なる安全性を高めるための工夫を講じたもので、それに係る構成以外は実施の形態１のものと同じである。従って、実施の形態１のものと同じ部分については、実施の形態１のものと同じ符号を用い、それらについての説明は省略する。
【００３１】
本実施の形態の太陽電池パネル１は、上側フレーム５に構成した配線固定部３５のウェブ部２２に、リード線３１，３２を構造面から浮かせて保持するための保持手段としてのケーブルリテーナ３６を設けたものである。ケーブルリテーナ３６は、難燃性のプラスチックで構成され、リード線３１，３２を保持する保持部３７に脚付きの取付構造３８を一体成形した構造である。ウェブ部２２に開けた取付孔に取付構造３８を嵌め込むことによってウェブ部２２の中間に複数個が装着され、リード線３１，３２をウェブ部２２からもフランジ１９からも浮かせて保持する。ケーブルリテーナ３６の取付位置は、図１１に示すようにコネクタ接続部に近接する位置が、コネクタ接続部の自重による弛みができず、リード線３１，３２を安定良く保持できるので都合が良い。こうした構成を採用することにより、電気系統から他部材への延焼を防止でき、太陽電池パネル１及びそれによる屋根構造２の安全性を一段と高めることができる。これ以外の構成及び機能は実施の形態１のものと同じである。

BACKGROUND OF THE INVENTION
The present invention relates to a solar cell panel in the form of a flat plate, which is a main body of photovoltaic power generation, and a roof structure of a house constituted by the solar cell panel.
[0002]
[Prior art]
Many solar panels used for photovoltaic power generation have a plurality of electrically connected solar cells sandwiched between a surface protection substrate and a back surface protection material, and between the surface protection substrate and the back surface protection material. A configuration is adopted in which an aluminum frame is attached to the periphery of a base plate formed by forming a filler layer into a square disk shape. The frame is made of extruded aluminum material with a cross-sectional shape with a groove to fit the end face of the base, and viscoelastic waterproofing material such as butyl rubber and silicon rubber to prevent intrusion of moisture, water vapor, etc. from the end It is fitted on the end face of the base via a groove. Such a solar cell panel is often installed on a roof or the like via a mount, but the solar cell panel itself may constitute a roof structure of a house.
[0003]
For example, Japanese Patent Application Laid-Open No. 5-280168 has adopted a roof structure using solar cell panels. That is, as shown in FIGS. 13 and 14, a vertical receiving frame 41 in which the receiving surface 40 is formed in a stepped shape from the ridge side to the eave side is fixed to the multi-row roof surface 42 from the ridge side to the eave side. . A horizontal receiving frame 43 is arranged toward the wife side, and the solar cell panel 44 is fixed in a stepped manner so that the edge portion overlaps the receiving surface 40. The eaves side edge of the upper solar cell panel 44 is placed on the horizontal receiving frame 43 into which the ridge side edge of the lower solar cell panel 44 fits, and the upper solar cell panel 44 and The horizontal receiving frame 43 is clamped by a U-shaped clip. The intermediate vertical receiving frame 41 is configured in a channel shape, and rainwater that enters from the mating portion of the solar cell panels 44 is drained to the eaves side by the channel. The vertical receiving frame 41 at the end on the wife side is bent at the edge on the roof surface 42 side, and rain water flowing down from the end edge of the solar cell panel 44 in the wife side row is drained to the eave side.
[0004]
As for the wiring of the positive and negative lead wires for taking out the output voltage drawn from each solar cell panel, a wiring duct is provided in the wiring duct, or disclosed in JP-A-5-167096, As also shown in FIG. 15, a wiring duct 46 is integrally formed on a gantry that holds the base 45, and lead wires 47 are wired in the wiring duct 46. The wiring duct 46 has a channel structure with an open top, and after the connection is made, the open portion is closed by the lid 48 in a state where it is kept watertight. In this roof structure, all the operations related to assembly and wiring can be performed from the surface side, and it is easy to construct and has good workability.
[0005]
[Problems to be solved by the invention]

In addition, in the conventional roof structure using solar cell panels, the lead wire 47 is connected and the wiring is completed, and then the wiring duct 46 must be subjected to a watertight holding treatment and covered with a lid 48. Nonetheless, the construction requires considerable work.
[0006]

Next, the roof structure 2 of the house comprised by the solar cell panel 1 of the structure mentioned above is demonstrated. Here, for the sake of explanation, the upper frame 5 is referred to as a ridge side frame, and the lower frame 6 is referred to as an eaves side frame. Moreover, the ridge side said here is synonymous with the upper side in an installation state, and the eaves side is synonymous with the lower side in an installation state. As shown in FIGS. 7, 8, 9, and 10, the roof structure 2 is configured by arranging a plurality of solar battery panels 1 in a row from the eave side to the ridge side on a roof base plate 27. The base plate 27 is inclined downward from the ridge side toward the eaves side, and the edge of the eaves side of the solar panel 1 on the ridge side is on the ridge side frame 5 of the solar panel 1 on the eave side. Are sequentially arranged so as to overlap with each other, and are fixed on the base plate 27 by screws.

The roof material 29 on the side is overlapped with the eaves member 28 and arranged so that the vertical frame 8 having the third eaves structure 16 faces the eaves member 28 side, thereby forming the roof structure 2 by the solar cell panel 1. The lower ridge 11 of the vertical frame 7 of the ridge-side solar panel 1 is fitted into the engagement portion 18 of the ridge-side frame 5 of the eave-side solar cell panel 1, and the inner ridge 9 is the ridge-side solar cell panel 1 ridge. Overlaid on the side frame 5 (see FIGS. 9 and 10). A plurality of such arrays are arranged in the wife direction to form a roof structure 2 made of the solar cell panel 1. The solar panels 1 on the side of the wife are joined to each other by joining the vertical frame 8 having the third flange structure 16 adjacent to the vertical frame 7 having the inner flange 9 and the lower flange 11 to the engaging portion 12. Is done. The joint portion and the third heel structure 16 are received by a portion protruding to the outside of the lower heel 11.
[0025]
The electrical connection between the solar cell panels 1 adjacent to each other in the wife direction is performed by connecting the male connector 34 of the lead wire 32 to the female side of the lead wire 31 of the adjacent solar cell panel 1 in the wiring fixing portion 35 opened to the outside. This is done by connecting to the connector 33 and connecting the female connector 33 of the lead wire 31 to the male connector 34 of the lead wire 32 of another adjacent solar cell panel 1 (see FIG. 10). At this time, one connector connecting portion of the lead wires 31 and 32 is arranged for each wiring fixing portion 35 of each solar cell panel 1 as shown in FIG. By adopting this wiring configuration, the two lead wires 31 and 32 do not come into contact with each other, and the connector connecting portion is also one by one. However, this can be prevented for the spread of fire.
[0026]
In the roof structure 2 of the solar cell panel 1 having such a structure, rainwater that has entered the inner ridge 9 of the solar cell panel 1 on the ridge side flows down the inner ridge 9, and the lower surface of the bottom portion on the lower end side is scraped off. It flows down to the surface of the solar cell panel 1 on the eaves side from the established water flow hole 10, and then flows down the surface of the solar cell panel 1 and drains at the eaves side end (first rainwater flow path). Rainwater that has entered the lower rail 11 flows down the lower rail 11 and flows from the lower end thereof to the horizontal structure 20 formed on the ridge-side frame 5 of the solar cell panel 1 on the eaves side. Then, it flows down to the inner flange 9 of the vertical frame 7 of the solar cell panel 1 on the eaves side (second rainwater flow path).
[0027]
Part of the rainwater that has flowed into the recumbent structure 20 is collected from the gap between the butted portions to the extension 14 of the lower reed 11 and the third reed structure 16 in the vertical frames 7 and 8 of the solar panel 1 on the eaves side. (3rd rainwater flow path). The rainwater diverted to the lower shell 11 of the eaves-side solar cell panel 1 is further diverted and flowed sequentially as described above in the recumbent structure 20 of the eaves-side solar cell panel 1. Further, the rainwater that has been diverted to the inner tub 9 of the eaves-side solar cell panel 1 flows down to the surface of the eaves-side solar cell panel 1 and sequentially passes through the first rainwater flow path described above. It flows down the surface and drains at the edge of the eaves side.
[0028]
Rainwater that has entered the third eaves structure 16 of the vertical frame 8 flows down the vertical frames 8 communicated by the water flow holes 17 and is drained at the eaves tip (fourth rainwater flow path). The horizontal structure 20 of the ridge-side frame 5 receives rainwater that enters from the mating part of the ridge-side frames 5 between the solar cell panels 1 adjacent to each other in the wife direction, and is formed vertically by the water holes 23 formed in the web portion 22. This is a structure for diverting to a certain inner ridge 9 and a third ridge structure 16.
[0029]
As described above, the solar cell panel 1 has a roof structure 2 in which the solar cell panel 1 is provided with a dredging structure as a drainage structure having three rows in the vertical direction and one row in the horizontal direction. Therefore, the roof structure 2 can be constructed without specially constructing the drainage structure on the field board 27, and the labor and cost of construction can be reduced. In addition, compared to the roof structure drained by a vertical row of eaves members for each row, the structure that drains from the lower eaves 11 to the inner eaves 9 and the surface of the base 3, the capacity of the eaves can be set small, and the flat area of the roof It can be used more effectively. Furthermore, since the rainwater flow path that sequentially diverts toward the eaves side is constituted by the water flow holes 23 of the recumbent structure 20, the amount of treated rainwater does not increase toward the eaves side, and the rainwater smoothly Wastewater treatment is possible.
