Description

この発明は太陽光パネルを備えた屋根に関し、特にたとえば、瓦と太陽光パネルとの合い葺きである、太陽光パネルを備えた屋根に関する。   The present invention relates to a roof provided with a solar panel, and more particularly, to a roof provided with a solar panel, which is a combination of a tile and a solar panel.

従来、一般住宅等の屋根に太陽光パネルを設ける場合には、瓦葺きの上に架台等を設け、その架台等の上に太陽光パネルを取り付けていた。しかし、これでは太陽光パネルが屋根から突出し、外観が見苦しい。特に、軒先側の金属屋根の上に被せるように和瓦を載せることによって軒先部を繊細に見せる一文字葺きに、太陽光パネルを搭載すると、一文字葺きの日本建築的な美観が損なわれてしまう。   Conventionally, when a solar panel is provided on a roof of a general house or the like, a frame or the like is provided on the roof tile, and the solar panel is attached on the frame or the like. However, with this, the solar panel protrudes from the roof, and the appearance is unsightly. In particular, when a solar panel is mounted on a single-letter that makes the eaves part delicately visible by placing a Japanese tile on the metal roof on the eaves side, the Japanese-style aesthetic of that single-lettering is impaired.

このような問題を軽減するため、太陽光パネルを屋根に一体的に組み込むための技術が特許文献１に開示される。特許文献１の技術では、太陽光パネル設置部分の母屋上面の高さを、瓦などが設置される一般屋根部の母屋上面の高さよりも低くすることによって、屋根の基礎下地に段差を設けている。そして、太陽光パネル設置部分の基礎下地に金属板等の板葺きを設置し、その上に太陽光パネルを設けることによって、太陽光パネルが一般屋根部から突出しない構造としている。
特開平１０−１６９１２９号公報［Ｅ０４Ｄ １３／１８］ In order to alleviate such a problem, Patent Document 1 discloses a technique for integrating a solar panel into a roof. In the technique of Patent Document 1, a step is provided on the foundation foundation of the roof by making the height of the upper surface of the main roof of the solar panel installation part lower than the height of the upper surface of the main roof of the general roof part where tiles and the like are installed. Yes. And it is set as the structure where a solar panel does not protrude from a general roof part by installing boarding, such as a metal plate, on the foundation ground of a solar panel installation part, and providing a solar panel on it.
JP-A-10-169129 [E04D 13/18]

しかし、特許文献１の技術では、屋根の基礎下地に段差を設けるため、一般的な屋根の基礎下地と異なる構造となる。したがって、他の一般的な屋根と兼用できない部材が多く、新規に部材の設定をする必要があるので、コストが高くなる。また、太陽光パネルの裏面が換気されにくい構造となっているため、特に夏場などには、太陽光パネルが高温になり、太陽光パネルのエネルギ変換効率が低下するという問題が生じる。   However, in the technique of Patent Document 1, since a step is provided on the basic foundation of the roof, the structure is different from that of a general basic foundation of the roof. Therefore, there are many members that cannot be shared with other general roofs, and it is necessary to newly set the members, which increases the cost. Moreover, since the back surface of the solar panel has a structure that is difficult to ventilate, particularly in summer, the solar panel becomes high temperature, resulting in a problem that the energy conversion efficiency of the solar panel is reduced.

それゆえに、この発明の主たる目的は、新規な、太陽光パネルを備えた屋根を提供することである。   Therefore, the main object of the present invention is to provide a novel roof with solar panels.

この発明の他の目的は、太陽光パネルを備えながらも日本建築的な美感を表現できる、太陽光パネルを備えた屋根を提供することである。   Another object of the present invention is to provide a roof provided with a solar panel that can express a Japanese architectural beauty while having a solar panel.

この発明のさらに他の目的は、コストを抑制できる、太陽光パネルを備えた屋根を提供することである。   Still another object of the present invention is to provide a roof provided with a solar panel, which can reduce costs.

この発明のさらに他の目的は、温度上昇による太陽光パネルのエネルギ変換効率の低下を防止できる、太陽光パネルを備えた屋根を提供することである。   Still another object of the present invention is to provide a roof provided with a solar panel that can prevent a decrease in energy conversion efficiency of the solar panel due to a temperature rise.

本発明は、上記の課題を解決するために、以下の構成を採用した。なお、括弧内の参照符号および補足説明などは、本発明の理解を助けるために後述する実施の形態との対応関係を示したものであって、本発明を何ら限定するものではない。   The present invention employs the following configuration in order to solve the above problems. Note that reference numerals in parentheses, supplementary explanations, and the like indicate correspondence relationships with embodiments described later to help understanding of the present invention, and do not limit the present invention in any way.

As a result, it is possible to express the aesthetics of the one-lettering that arranges Japanese tiles so as to cover the metal roof on the eave side, that is, the aesthetics of Japanese architecture, with the roof tiles and the solar panels on the eaves side.

また、従来の工法によって面一に形成される基本屋根下地を基礎としているため、新規の納まりでも従来の工業化製品の部材を使用でき、新規に部材を設定することと比較してコストを抑えることができる。   In addition, because it is based on the basic roof foundation that is formed flush with the conventional construction method, it is possible to use the members of the conventional industrialized products even in new housing, and to reduce costs compared to setting new members Can do.

請求項２の発明は、請求項１の発明に従属し、瓦屋根下地は、外部と勾配方向に連通する第２空気通路を備える。   The invention of claim 2 is dependent on the invention of claim 1, and the tile roof foundation includes a second air passage communicating with the outside in a gradient direction.

請求項２の発明では、瓦屋根下地（２６）に、外部と勾配方向に連通する第２空気通路（３４）を設ける。このように、軒側に太陽光パネル（１４）を設け、その棟側に第２空気通路を有する瓦屋根下地を設けることで、太陽光パネルの裏面の熱せられた空気は、太陽光パネルと太陽光パネル下地（４８）との間の第１空気通路を通って棟側に向かって上昇し、瓦屋根下地の第２空気通路を通って外部に排出される。   In the invention of claim 2, the tile roof base (26) is provided with a second air passage (34) communicating with the outside in a gradient direction. Thus, by providing a solar panel (14) on the eave side and providing a tiled roof base having a second air passage on the ridge side, the heated air on the back surface of the solar panel is It rises toward the building through the first air passage between the solar panel substrate (48) and is discharged to the outside through the second air passage of the tile roof substrate.

Decline can be prevented.

請求項３の発明は、請求項１または２の発明に従属し、瓦屋根下地は、基本屋根下地上に勾配方向に設けられる勾配桟、基本屋根下地上に水平方向に設けられる水平桟、勾配桟と水平桟とによって支持される板材、および第２空気通路を勾配方向に外部と連通するために水平桟に形成される切り欠きを備える。   The invention according to claim 3 is dependent on the invention according to claim 1 or 2, wherein the tile roof base is a gradient beam provided in a gradient direction on the basic roof substrate, a horizontal beam provided in a horizontal direction on the basic roof substrate, a gradient A plate member supported by the crosspiece and the horizontal crosspiece, and a notch formed in the horizontal crosspiece to communicate the second air passage with the outside in the gradient direction.

請求項３の発明では、瓦屋根下地（２６）は、勾配桟（２８）、水平桟（３０）、および勾配桟と水平桟とによって支持される板材（３２）などによって形成される。また、瓦屋根下地は、基本屋根下地（２４）と板材との間に形成される第２空気通路（３４）を有する。水平桟には、切り欠け（３６）が設けられており、この切り欠けを介して、第２空気通路は勾配方向に外部と連通する。したがって、請求項２の発明と同様に、太陽光パネルの裏面の熱せられた空気は、その裏面の第１空気通路を通って棟側に向かって流れ、瓦屋根下地の第２空気通路を通って外部に排出されるので、太陽光パネルの温度上昇を抑えることができ、温度上昇による太陽光パネルのエネルギ変換効率の低下を防止できる。   In the invention of claim 3, the tile roof base (26) is formed by the gradient beam (28), the horizontal beam (30), and the plate material (32) supported by the gradient beam and the horizontal beam. Further, the tile roof base has a second air passage (34) formed between the basic roof base (24) and the plate material. The horizontal bar is provided with a notch (36), and the second air passage communicates with the outside in the gradient direction through the notch. Therefore, as in the second aspect of the invention, the heated air on the back surface of the solar panel flows toward the ridge side through the first air passage on the back surface, and passes through the second air passage on the tile roof base. Therefore, the temperature rise of the solar panel can be suppressed, and the energy conversion efficiency of the solar panel can be prevented from being lowered due to the temperature rise.

請求項４の発明は、請求項１ないし３のいずれかの発明に従属し、瓦屋根下地はその上面が太陽光パネルの上面と同一面となるように設けられる。   The invention of claim 4 is dependent on the invention of any one of claims 1 to 3, and the tile roof base is provided so that the upper surface thereof is flush with the upper surface of the solar panel.

請求項４の発明では、瓦屋根下地（２６）の所定高さは、瓦屋根下地の上面と太陽光パネル（１４）の上面とが同一面となるように設定される。   In the invention of claim 4, the predetermined height of the tile roof foundation (26) is set so that the upper surface of the tile roof foundation and the upper surface of the solar panel (14) are flush with each other.

請求項４の発明によれば、瓦屋根下地の上面と太陽光パネルの上面とを同一面としたので、太陽光パネルと瓦とを隙間無く連続するように施工することが可能となる。したがって、軒側の金属屋根に被るように和瓦を乗せる一文字葺き本来の一体感のある美観をより表現できる。   According to invention of Claim 4, since the upper surface of the tile roof base | substrate and the upper surface of the solar panel were made into the same surface, it becomes possible to construct so that a solar panel and a tile may continue without a gap. Therefore, it is possible to more express the original aesthetic appearance of a single character that puts Japanese tiles on the eaves side metal roof.

この発明によれば、瓦と太陽光パネルとによって日本建築的な美観を表現できる。また、従来と同様に形成される面一の基本屋根下地を基礎としているため、新規の納まりでも新規の部材を設定する必要が無く、従来の工業化製品を使用できるので、コストを抑制できる。さらに、瓦屋根下地に第２空気通路を形成すれば、太陽光パネルの裏面の熱せられた空気を効率よく換気できるので、太陽光パネルの温度上昇を抑えることができ、温度上昇による太陽光パネルのエネルギ変換効率の低下を防止できる。   According to this invention, a Japanese architectural beauty can be expressed by the roof tile and the solar panel. Moreover, since it is based on the same basic roof base | substrate formed similarly to the past, it is not necessary to set a new member even if it is new, and since the conventional industrialized product can be used, cost can be suppressed. Furthermore, if the second air passage is formed in the tile roof base, the heated air on the back of the solar panel can be efficiently ventilated, so that the temperature rise of the solar panel can be suppressed, and the solar panel due to the temperature rise It is possible to prevent a decrease in energy conversion efficiency.

この発明の上述の目的，その他の目的，特徴および利点は、図面を参照して行う以下の実施例の詳細な説明から一層明らかとなろう。   The above object, other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments with reference to the drawings.

図１を参照して、この実施例の太陽光パネルを備えた屋根１０（以下、単に「屋根１０」という。）は、たとえば、数奇屋風一文字葺き住宅１２（以下、単に「住宅１２」という。）の南に面する屋根に適用される。一般的に、一文字葺きとは、和瓦と軒先側の金属屋根、たとえば銅板とで構成される合い葺きのことをいうが、この実施例では、金属屋根の代わりに太陽光パネル１４を設ける。つまり、棟側の和瓦１６と軒側の太陽光パネル１４との合い葺きによって、一文字葺きの日本建築的な美観を表現する。なお、この実施例では、図示は省略するが、住宅１２の東、西および北に面する屋根には、屋根１０を適用しない。よって、その全面に和瓦１６が従来通りに葺かれ、後述する瓦屋根下地２６は設けられない。   With reference to FIG. 1, a roof 10 (hereinafter simply referred to as “roof 10”) having a solar panel of this embodiment is referred to as a “sukiya” single-lettered house 12 (hereinafter simply referred to as “house 12”), for example. Applies to the roof facing south). In general, one-lettering refers to a combination of a Japanese roof tile and a metal roof on the eaves side, for example, a copper plate. In this embodiment, a solar panel 14 is provided instead of the metal roof. In other words, by combining the Japanese roof tiles 16 on the ridge side and the solar panels 14 on the eaves side, a Japanese architectural aesthetic with a single lettering is expressed. In this embodiment, although illustration is omitted, the roof 10 is not applied to the roof facing the east, west and north of the house 12. Therefore, the Japanese tile 16 is spread over the entire surface as usual, and the tile roof base 26 described later is not provided.

図１に示すように、屋根１０は、太陽光パネル部１８および瓦部２０を含む。太陽光パネル部１８は、屋根１０の軒側および妻側に並ぶように設けられる太陽光パネル１４等によって構成される。太陽光パネル１４は、複数の太陽電池セルを備え、強化ガラスや封止材などによって方形状にパッケージ化されたものである。また、その周囲には、金属や樹脂などによって形成されるフレーム５６（図２参照）が方形枠状に取り付けられている。フレーム５６の端部には、「コ」字状の断面形状を有する受部が形成されており、この受部に嵌め込むように後述する太陽光パネル固定金具５０の接続部が接続される。このような太陽光パネル１４には、公知の太陽光パネルを用いることができる。たとえば、三洋電機株式会社製のＨＩＴ（Heterojunction with Intrinsic Thin-layer）太陽電池（型番：ＨＩＰ−２００Ｂ２）を用いることができる。   As shown in FIG. 1, the roof 10 includes a solar panel portion 18 and a tile portion 20. The solar panel unit 18 is configured by a solar panel 14 provided so as to be arranged on the eaves side and the wife side of the roof 10. The solar panel 14 includes a plurality of solar cells and is packaged in a rectangular shape by tempered glass or a sealing material. In addition, a frame 56 (see FIG. 2) formed of metal, resin, or the like is attached to the periphery thereof in a rectangular frame shape. A receiving portion having a “U” -shaped cross-sectional shape is formed at the end of the frame 56, and a connecting portion of a solar panel fixing metal fitting 50 described later is connected so as to be fitted into the receiving portion. A known solar panel can be used for such a solar panel 14. For example, an HIT (Heterojunction with Intrinsic Thin-layer) solar cell (model number: HIP-200B2) manufactured by Sanyo Electric Co., Ltd. can be used.

また、瓦部２０は、屋根１０の棟側に葺かれる和瓦１６等によって構成される。和瓦１６には、従来の和瓦を用いることができる。   Further, the tile portion 20 is configured by a Japanese tile 16 or the like that is laid on the ridge side of the roof 10. As the Japanese roof tile 16, a conventional Japanese roof tile can be used.

なお、所定の大きさの太陽光パネル１４では、屋根１０の軒先側および妻側を適切に葺くこと、すなわち軒先側および妻側の全面を隙間無く覆うことができない場合がある。このような場合には、たとえば、軒先側の水平方向の端部や妻側の勾配方向の端部に、ダミーモジュール２２を設けるとよい。ダミーモジュール２２は、発電には利用されないが、外観が太陽光パネル１４と類似しており、所望の形状への加工が容易なものである。ダミーモジュール２２としては、たとえば、アルミニウム板の表面に太陽光パネル１４のセルパターンを印刷したフィルムを貼り付けたもの等を使用するとよい。   In some cases, the solar panel 14 having a predetermined size may not properly cover the eaves side and the wife side of the roof 10, that is, cannot cover the entire surface of the eaves side and the wife side without a gap. In such a case, for example, the dummy module 22 may be provided at the end in the horizontal direction on the eaves side or the end in the gradient direction on the wife side. The dummy module 22 is not used for power generation, but has an appearance similar to that of the solar panel 14 and can be easily processed into a desired shape. As the dummy module 22, for example, a film in which a cell pattern of the solar panel 14 is attached to the surface of an aluminum plate may be used.

また、図２〜図５に示すように、屋根１０は、屋根１０の基礎となる基本屋根下地２４を含み、この基本屋根下地２４の上に、上述の太陽光パネル部１８および瓦部２０が形成される。また、基本屋根下地２４と瓦部２０との間には、瓦屋根下地２６が設けられる。   Moreover, as shown in FIGS. 2-5, the roof 10 contains the basic roof base 24 used as the foundation of the roof 10, and the above-mentioned solar panel part 18 and the tile part 20 are on this basic roof base 24. As shown in FIG. It is formed. In addition, a tile roof base 26 is provided between the basic roof base 24 and the tile portion 20.

勾配桟２８は、たとえば高さ５０ｍｍ×幅４５ｍｍの木桟であって、瓦屋根下地２６の水平方向の両端部、およびその水平方向の両端部を等分するような位置に、所定間隔毎（たとえば、４５５ｍｍ毎）に勾配方向に延びて設けられる。   The gradient bars 28 are, for example, wooden bars having a height of 50 mm and a width of 45 mm, and are arranged at predetermined intervals (at intervals between the both ends in the horizontal direction of the tile roof base 26 and the both ends in the horizontal direction). For example, every 455 mm) is provided extending in the gradient direction.

水平桟３０は、たとえば高さ５０ｍｍ×幅４５ｍｍの木桟であって、瓦屋根下地２６の勾配方向の両端部に水平方向に延びて設けられる。ただし、瓦屋根下地２６の勾配方向の長さが長い場合には、瓦屋根下地２６の強度を確保するため、その勾配方向の両端部を等分するような位置に、適宜水平桟３０を設けてもよい。また、水平桟３０のそれぞれには、図４に示すように、水平方向に所定の間隔を隔てて、たとえば断面が矩形の切り欠き３６が形成される。この切り欠き３６は、勾配桟２８と重ならない位置、たとえば各勾配桟２８の間に位置するように設けるとよい。この切り欠き３６によって、第２空気通路３４は、瓦屋根下地２６の軒側端部から棟側端部に亘って勾配方向に連通し、外部と連通する。   The horizontal bars 30 are, for example, wooden bars having a height of 50 mm and a width of 45 mm, and are provided to extend in the horizontal direction at both ends of the tile roof base 26 in the gradient direction. However, when the tile roof base 26 is long in the gradient direction, horizontal bars 30 are appropriately provided at positions where both ends of the tile roof base 26 are equally divided in order to ensure the strength of the tile roof base 26.

The notches 36 are preferably provided so as not to overlap the gradient bars 28, for example, between the gradient bars 28. By this cutout 36, the second air passage 34 communicates in the gradient direction from the eaves side end portion to the ridge side end portion of the tile roof base 26, and communicates with the outside.

板材３２は、たとえば厚さ１２ｍｍの木製の合板であって、和瓦１６が敷設される全域に亘って設けられる。この板材３２は、その上面が、太陽光パネル１４を基本屋根下地２４の上に設置したときに、太陽光パネル１４の上面と略同一面となるように設けられる。言い換えると、瓦屋根下地２６の高さ（この実施例では６２ｍｍ）は、太陽光パネル１４の上面の高さ位置などを考慮して設定され、瓦屋根下地２６の上面と太陽光パネル１４の上面とは略同一面とされる。   The plate material 32 is, for example, a wooden plywood having a thickness of 12 mm, and is provided over the entire area where the Japanese roof tiles 16 are laid. The plate 32 is provided so that the upper surface thereof is substantially flush with the upper surface of the solar panel 14 when the solar panel 14 is installed on the basic roof foundation 24. In other words, the height of the tile roof base 26 (62 mm in this embodiment) is set in consideration of the height position of the upper surface of the solar panel 14, and the upper surface of the tile roof base 26 and the upper surface of the solar panel 14. Are substantially flush with each other.

このような瓦屋根下地２６の上に、瓦部２０が設けられる、つまり和瓦１６が葺かれる。具体的には、瓦屋根下地２６の表面には、ルーフィング３８が敷かれ、瓦屋根下地２６の側面には、水切材４０や捨水切材４２などが適宜取り付けられる。そして、瓦屋根下地２６の上面には、たとえば樹脂製の瓦桟４４や鼻桟４６などが取り付けられ、その瓦桟４４などの上に和瓦１６が設けられる。なお、瓦屋根下地２６の勾配方向の端部を形成する水平桟３０には、切り欠け３６が形成されるので、その水平桟３０の切り欠け３６に合わせて、ルーフィング３８や捨水切材４２などにも適宜切り欠け、或いは通気孔が形成される。瓦屋根下地２６の軒側端部に設けられる捨水切材４２（図６参照）は、上壁部４２ａ、側壁部４２ｂおよび下壁部４２ｃを備える。上壁部４２ａの一方端と下壁部４２ｃとには、突起部４２ｄ，４２ｅが形成され、この突起部４２ｄ，４２ｅによって、瓦屋根下地２６内部への雨水等の侵入が防がれる。また、側壁部４２ｂには、水平桟３０の切り欠け３６に対応する位置に通気孔４２ｆが形成され、この通気孔４２ｆや切り欠け３６を介して、第２空気通路３４に空気が流入する。   The tile portion 20 is provided on the tile roof base 26, that is, the Japanese tile 16 is spread. Specifically, a roofing 38 is laid on the surface of the tile roof base 26, and a draining material 40, a drainage cutting material 42, and the like are appropriately attached to the side surface of the tile roof base 26. For example, a resin-made tile crosspiece 44 or a nose crosspiece 46 is attached to the upper surface of the tile roof base 26, and the Japanese tile 16 is provided on the tile crosspiece 44. In addition, since the notch 36 is formed in the horizontal rail 30 which forms the edge part of the gradient direction of the tile roof base 26, according to the notch 36 of the horizontal rail 30, the roofing 38, the drainage cutting material 42, etc. Also, notches or vent holes are formed as appropriate. The drainage cutting material 42 (see FIG. 6) provided at the eaves side end of the tile roof base 26 includes an upper wall portion 42a, a side wall portion 42b, and a lower wall portion 42c. Projection portions 42d and 42e are formed on one end of the upper wall portion 42a and the lower wall portion 42c, and rainwater or the like can be prevented from entering the tile roof base 26 by the projection portions 42d and 42e. In addition, a vent hole 42f is formed in the side wall portion 42b at a position corresponding to the notch 36 of the horizontal bar 30, and air flows into the second air passage 34 through the vent hole 42f and the notch 36.

また、上述したように、基本屋根下地２４の瓦屋根下地２６が設けられる範囲を除く範囲には、太陽光パネル１４が並ぶように設けられて、太陽光パネル部１８が形成される。具体的には、太陽光パネル部１８が形成される範囲の基本屋根下地２４の上面には、ルーフィング３８を介して、防水性を有する太陽光パネル下地４８、たとえばカラーベストなどのスレート葺き材が葺かれる。そして、その太陽光パネル下地４８の上に太陽光パネル１４が取り付けられる。太陽光パネル１４を取り付ける際には、太陽光パネル下地４８の上面に取り付けられる太陽光パネル固定金具５０や基本屋根下地２４の軒先に取り付けられる浮き止め金具５２などの固定部材が用いられる。   In addition, as described above, the solar panel portion 18 is formed by arranging the solar panels 14 in a range excluding the range where the tile roof base 26 of the basic roof base 24 is provided. Specifically, on the upper surface of the basic roof base 24 in the range where the solar panel portion 18 is formed, a waterproof solar panel base 48, for example, a slate firewood such as a color vest, is provided via a roofing 38. I will be beaten. Then, the solar panel 14 is attached on the solar panel base 48. When the solar panel 14 is attached, a fixing member such as a solar panel fixing bracket 50 attached to the upper surface of the solar panel base 48 or a floating stopper 52 attached to the eaves of the basic roof base 24 is used.

太陽光パネル固定金具５０は、たとえば厚さ１３ｍｍの板状の基板および太陽光パネル１４のフレーム５６の受部と連結される連結部を備え、この基板によってフレーム５６を支持し、連結部によってフレーム５６を固定する。この太陽光パネル固定金具５０によって、太陽光パネル１４のフレーム５６は、太陽光パネル下地４８から所定間隔（この実施例では、１３ｍｍ）浮かせた状態で固定される。つまり、太陽光パネル１４と太陽光パネル下地４８との間に第１空気通路５８が形成される。したがって、太陽光パネル固定金具５０が、第１空気通路５８を形成する空気通路形成手段として機能する。   The solar panel fixing metal fitting 50 includes, for example, a plate-like substrate having a thickness of 13 mm and a connecting portion connected to the receiving portion of the frame 56 of the solar panel 14, and the frame 56 is supported by the substrate. 56 is fixed. With this solar panel fixing bracket 50, the frame 56 of the solar panel 14 is fixed in a state of being floated from the solar panel base 48 by a predetermined interval (13 mm in this embodiment). That is, the first air passage 58 is formed between the solar panel 14 and the solar panel base 48. Therefore, the solar panel fixing bracket 50 functions as an air passage forming means for forming the first air passage 58.

また、浮き止め金具５２は、略直角に屈曲した押さえ金具であって、その一方端が釘やねじ等によって軒先に固定されると、他端は上方に向かって突出する。その上方に突出した他端と太陽光パネル１４のフレーム５６とが、ねじ等によって接続されて、太陽光パネル１４は太陽光パネル下地４８から浮き止めされる。なお、このようにして設置された太陽光パネル１４の上面の高さは、基本屋根下地を基準として、６５ｍｍである。これは、瓦屋根下地２６の高さ（６２ｍｍ）とほぼ同じである。   In addition, the floating metal fitting 52 is a holding metal bent at a substantially right angle, and when one end thereof is fixed to the eaves by a nail or a screw, the other end protrudes upward. The other end protruding upward and the frame 56 of the solar panel 14 are connected by screws or the like, so that the solar panel 14 is floated from the solar panel base 48. In addition, the height of the upper surface of the solar panel 14 installed in this way is 65 mm on the basis of the basic roof foundation. This is substantially the same as the height (62 mm) of the tile roof base 26.

また、図２に示すように、瓦部２０の棟部には、棟部換気部材５４が設けられる。棟部換気部材５４には公知の部材を用いてよく、棟部換気部材５４は、屋根裏の空気を換気すると共に、瓦屋根下地２６の内部の空気も換気する。   Further, as shown in FIG. 2, a ridge ventilation member 54 is provided in the ridge of the roof tile 20. A well-known member may be used for the ridge ventilation member 54, and the ridge ventilation member 54 ventilates air in the attic and also ventilates the air inside the tile roof base 26.

このように、屋根１０の軒側に太陽光パネル１４を設け、その棟側に外部と連通する第２空気通路３４を有する瓦屋根下地２６を設けることで、軒側に設置される太陽光パネル１４の裏面の熱せられた空気は、棟側に向かって上昇するように第１空気通路５８を流れ、瓦屋根下地２６の第２空気通路３４を通って、棟部の棟部換気部材５４を介して外部に排出される。これによって、太陽光パネル１４の裏面は効率よく換気されるので、太陽光パネル１４の温度上昇を抑えることができ、温度上昇による太陽光パネル１４のエネルギ変換効率の低下を防止できる。したがって、太陽光パネル１４による自家発電量を増加でき、夏場の電力供給不足に対しても貢献することができる。また、同様に、瓦部２０の温度上昇も抑えることができるので、屋根裏空間の温度上昇を抑制することもできる。   As described above, the solar panel 14 is provided on the eave side by providing the solar panel 14 on the eave side of the roof 10 and providing the tile roof base 26 having the second air passage 34 communicating with the outside on the ridge side. The heated air on the back surface of 14 flows through the first air passage 58 so as to rise toward the ridge side, passes through the second air passage 34 of the tile roof base 26, and passes through the ridge ventilation member 54 of the ridge portion. It is discharged to the outside. Thereby, since the back surface of the solar panel 14 is efficiently ventilated, the temperature rise of the solar panel 14 can be suppressed, and the decrease in the energy conversion efficiency of the solar panel 14 due to the temperature rise can be prevented. Therefore, the amount of private power generation by the solar panel 14 can be increased, and it can contribute to the shortage of power supply in summer. Moreover, since the temperature rise of the tile part 20 can also be suppressed similarly, the temperature rise of an attic space can also be suppressed.

また、従来の工法によって面一に敷設される基本屋根下地２４を基礎としたので、新規の納まりでも従来の工業化製品の部材を使用できる。したがって、新規に部材を設定することと比較して、コストを抑えることができる。   Moreover, since it was based on the basic roof base | substrate 24 laid in the same plane by the conventional construction method, the member of the conventional industrialized product can be used even if it is new. Therefore, costs can be reduced compared to setting a new member.

さらに、基本屋根下地２４と瓦部２０との間に所定高さを有する瓦屋根下地２６を設けることによって、和瓦１６と太陽光パネル１４とに段差を設けることができる。この段差を有することによって、金属屋根の上に被るように和瓦を葺き、軒先部を繊細に見せるという一文字葺きの美観を、和瓦１６と金属屋根の代わりに設けた太陽光パネル１４によって表現できる。したがって、太陽光パネル１４を備えながらも、日本建築的な美観を継承した建築物や日本的な町並みに対して配慮した建築物を提供できる。また、太陽光パネル１４による自家発電によって地球環境にも貢献できる。   Further, by providing a tile roof foundation 26 having a predetermined height between the basic roof foundation 24 and the tile portion 20, a step can be provided between the Japanese tile 16 and the solar panel 14. By having this level difference, the Japanese-style tiles are spread over the metal roof and the eaves of the eaves are shown delicately with the solar panel 14 provided instead of the Japanese tile 16 and the metal roof. it can. Accordingly, it is possible to provide a building that inherits the aesthetics of Japanese architecture and a building that takes into consideration the Japanese townscape while having the solar panel 14. In addition, self-power generation by the solar panel 14 can contribute to the global environment.

なお、上述の実施例では、和瓦１６に従来の和瓦を使用できるように、また、太陽光パネル１４のメンテナンス等が行い易いように、太陽光パネル部１８と瓦部２０との縁を切った納まりとした。つまり、太陽光パネル部１８と瓦部２０との間に隙間を設け、実際には和瓦１６が太陽光パネル１４に被らない納まりとしたが、これに限定されない。他の実施例として、たとえば、図７および図８に示すように、太陽光パネル１４を瓦屋根下地２６に隣接するように設けて、実際に和瓦１６が太陽光パネル１４に被る納まりにすることもできる。この場合には、瓦屋根下地２６の上面と太陽光パネル１４の上面とを同一面としているため、和瓦１６の軒側端部や妻側（ケラバ側）端部の下に、太陽光パネル１４がぴったりとはまり込むような状態になる。つまり、瓦屋根下地２６の上面と太陽光パネル１４の上面とを同一面とすることによって、太陽光パネル１４と和瓦１６とを隙間無く連続するように施工できるようになり、より一体感のあるすぐれた意匠を表現できる。したがって、図７および図８に示す実施例によれば、和瓦１６と金属屋根の代わりに設けた太陽光パネル１４によって、本来の一文字葺きの美観をより表現できる。ただし、この場合、瓦屋根下地２６のケラバ側端部に葺く和瓦１６（ケラバ瓦）には、従来のケラバ瓦よりもその端部１６ａ（図８参照）の上下方向の寸法が短い、一文字葺き用のケラバ瓦を使用する必要がある。   In addition, in the above-mentioned Example, the edge of the solar panel part 18 and the roof tile part 20 is attached so that the maintenance of the solar panel 14 etc. can be performed easily so that the traditional Japanese roof tile 16 can be used. It was cut off. That is, a gap is provided between the solar panel portion 18 and the roof tile portion 20 and the Japanese roof tiles 16 are not actually covered by the solar panel 14, but the present invention is not limited to this. As another embodiment, for example, as shown in FIGS. 7 and 8, the solar panel 14 is provided adjacent to the tile roof base 26 so that the Japanese tile 16 actually covers the solar panel 14. You can also. In this case, since the upper surface of the tile roof base 26 and the upper surface of the solar panel 14 are the same surface, the solar panel is placed below the eaves side end and the wife side (keraba side) end of the Japanese tile 16. 14 is in a state where it fits snugly. That is, by making the upper surface of the tile roof base 26 and the upper surface of the solar panel 14 the same surface, the solar panel 14 and the Japanese tile 16 can be constructed so as to be continuous without a gap, and a more integrated feeling can be achieved. A good design can be expressed. Therefore, according to the embodiment shown in FIG. 7 and FIG. 8, the original aesthetics of single lettering can be expressed more by the solar panel 14 provided instead of the Japanese tile 16 and the metal roof. However, in this case, the Japanese tile 16 (keraba tile) that goes to the keraba side end of the tile roof base 26 has a shorter vertical dimension at its end 16a (see FIG. 8) than the conventional keraba tile. It is necessary to use keraba roof tiles for single-lettering.

また、上述の各実施例では、瓦屋根下地２６の上面と太陽光パネル１４の上面とが同一面となるように、瓦屋根下地２６や太陽光パネル１４を敷設したが、これに限定されない。たとえば、瓦屋根下地２６の上面を太陽光パネル１４の上面よりも高くすることもできる。この場合には、瓦屋根下地２６の第２空気通路３４の断面積が大きくなるため、たとえば切り欠き３６を大きくすれば、換気機能がより強化され、太陽光パネル１４の裏面の熱せられた空気がより排出され易くなる。   Further, in each of the above-described embodiments, the tile roof base 26 and the solar panel 14 are laid so that the upper surface of the tile roof base 26 and the upper surface of the solar panel 14 are the same surface, but the present invention is not limited to this. For example, the upper surface of the tile roof base 26 can be made higher than the upper surface of the solar panel 14. In this case, since the cross-sectional area of the second air passage 34 of the tile roof foundation 26 is increased, for example, if the notch 36 is increased, the ventilation function is further enhanced and the heated air on the back surface of the solar panel 14 is heated. Is more easily discharged.

また、上述の各実施例では、水平桟３０に矩形の切り欠き３６を設けたが、これに限定されず、切り欠き３６の形状などは適宜変更され得る。また、勾配桟２８の設置間隔を狭くする等して、瓦屋根下地２６の強度が確保されるような場合には、水平桟３０を設けないようにしてもよい。   Further, in each of the embodiments described above, the rectangular notch 36 is provided in the horizontal bar 30, but the present invention is not limited to this, and the shape of the notch 36 can be changed as appropriate. Further, when the strength of the tile roof base 26 is ensured, for example, by reducing the installation interval of the gradient bars 28, the horizontal bars 30 may not be provided.

さらに、上述の各実施例では、屋根１０を住宅１２の南に面する屋根に適用したが、これに限定されず、屋根１０は、一般住宅を含む様々な建築物の屋根に適用され得る。もちろん、南以外の他の方角に面する屋根に適用することもできる。   Further, in each of the above-described embodiments, the roof 10 is applied to the roof facing the south of the house 12, but the present invention is not limited thereto, and the roof 10 can be applied to roofs of various buildings including general houses. Of course, it can also be applied to roofs facing other directions than the south.

また、上述の各実施例では、屋根１０の軒先側および妻側を並ぶように太陽光パネル１４を設置したが、これに限定されない。たとえば、屋根１０の軒先側だけに太陽光パネル１４を設けることもできる。   Moreover, in each above-mentioned Example, although the solar panel 14 was installed so that the eaves side and the wife side of the roof 10 may be located in a line, it is not limited to this. For example, the solar panel 14 can be provided only on the eaves side of the roof 10.
