Description

本発明は主に陸屋根の表面やコンクリートやレンガを敷設した地面の上面に、設置される太陽光発電装置に関するものである。   The present invention relates to a photovoltaic power generation apparatus installed mainly on the surface of a flat roof or the upper surface of a ground on which concrete or brick is laid.

従来、陸屋根の表面やコンクリートやレンガを敷設した地面の上面に、設置される太陽光発電装置は、鉄やアルミニウムなどのレールを組合わせた設置架台に、太陽電池モジュールを配置していた。具体的には、図１４に示すように、設置架台は、太陽光発電装置が風などにより飛ばされたり転倒させられたりしないように、設置面にコンクリート塊などで強固な基礎３１を形成して、基礎３１間に底部レール３２、太陽電池モジュール２０を固定する上部レール３３、太陽電池モジュール２０を支持するとともに傾斜角をつくる短辺レール３４、長辺レール３５のように複数のレールをボルト等で締め付け固定して構成していた。そして、太陽電池モジュール２０を上部レール３３に固定していた。   Conventionally, solar power generators installed on the surface of a flat roof or on the top surface of a ground laid with concrete or brick have been arranged with solar cell modules on an installation stand that combines rails such as iron and aluminum. Specifically, as shown in FIG. 14, the installation platform forms a solid foundation 31 with a concrete lump or the like on the installation surface so that the photovoltaic power generation device is not blown or overturned by wind or the like. A plurality of rails such as a bottom rail 32 between the foundations 31, an upper rail 33 for fixing the solar cell module 20, a short side rail 34 for supporting the solar cell module 20 and forming an inclination angle, and a long side rail 35. Tightened and fixed with. The solar cell module 20 is fixed to the upper rail 33.

このような従来の太陽光発電装置は、架台を一旦締め付け固定してしまうと太陽の高さに合わせて傾斜角度を容易に変更することができない。また、設置場所の移設も容易でないものであった。   In such a conventional solar power generation device, once the gantry is fastened and fixed, the inclination angle cannot be easily changed in accordance with the height of the sun. Moreover, it was not easy to move the installation location.

尚、太陽電池モジュールは、複数の太陽電池素子を直並列に接続し、強化ガラス・封入樹脂・耐候性フィルムで挟持した構造が一般的である。図１３に示すように、太陽電池モジュール２０は、受光面にガラスや樹脂等の光透過板１１が設けられ、この光透過板１１に多数の太陽電池素子１０がＥＶＡ樹脂（Ｅｔｈｙｌｅｎｅ−Ｖｉｎｙｌ Ａｃｅｔａｔｅ）等からなる充填材１６によってラミネートされ、その裏面である非受光面にはテフロン（登録商標）フィルムやＰＶＦ（ポリフッ化ビニル）、ＰＥＴ（ポレエチレンテレフタレート）などの耐候性フィルム１２が貼着されたものであり、太陽電池素子１０としては、例えばシリコン系半導体やガリウムヒ素等から成る化合物半導体などの単結晶、多結晶や非晶質の材料が用いられ、互いに直列及び／または並列に電気的に接続されて、太陽電池モジュール２０の裏面、すなわち耐候性フィルム１２の上にはＡＢＳ樹脂などの合成樹脂やアルミニウムなどで構成したジャンクションボックス１３を接着し、太陽電池モジュール２０の出力電力を取り出すターミナルに接続された送電線により出力が取り出される。なお、これら光透過板１１、太陽電池素子１０および耐候性フィルム１２の重ね構造の矩形状の本体に対し、その各辺周囲をアルミニウム金属やＳＵＳ等から成る枠体１５で挟み込むように装着し、太陽電池モジュール２０の設置用固定部の役割を果たすようにしている。また、太陽電池モジュール２０の端部保護および全体の強度を高める強度向上の目的にも役立つ。枠体１５には鉄やステンレス、アルミニウムのような金属の折り曲げ材や押し出し成形、ＦＲＰなどの樹脂成型品が用いられ、枠体同士の組付けは直接ネジやリベットで結合されるものや、連結プレートのような補助部材を介して固定されたり、ガラスや樹脂等の光透過板１１に接着することで行われる。また、一体成型された枠に光透過板１１をはめ込む構造としてもよい。   In general, a solar cell module has a structure in which a plurality of solar cell elements are connected in series and sandwiched between tempered glass, an encapsulating resin, and a weather resistant film. As shown in FIG. 13, the solar cell module 20 is provided with a light transmission plate 11 such as glass or resin on the light receiving surface, and a large number of solar cell elements 10 are formed on the light transmission plate 11 with EVA resin (Ethylene-Vinyl Acetate). A non-light-receiving surface which is a back surface thereof is laminated with a weathering film 12 such as a Teflon (registered trademark) film, PVF (polyvinyl fluoride), or PET (polyethylene terephthalate). As the solar cell element 10, for example, a single crystal, polycrystalline or amorphous material such as a compound semiconductor made of silicon-based semiconductor or gallium arsenide is used, and is electrically connected in series and / or in parallel with each other. Connected to the back surface of the solar cell module 20, that is, on the weather resistant film 12, there is a resin such as ABS resin. Bonding the junction box 13 which is configured by a resin or aluminum, an output is taken out by the transmission line connected to the terminal for taking out the output power of the solar cell module 20. The light transmitting plate 11, the solar cell element 10, and the weather resistant film 12 are attached to the rectangular main body so as to be sandwiched by a frame 15 made of aluminum metal, SUS, etc. The solar cell module 20 is configured to serve as a fixing portion for installation. Moreover, it is useful also for the purpose of the strength improvement which protects the edge part of the solar cell module 20, and raises the whole intensity | strength. The frame 15 is made of a metal bending material such as iron, stainless steel, and aluminum, or a resin molded product such as FRP, FRP, etc., and the assembly of the frames can be directly coupled with screws or rivets, It is performed by fixing through an auxiliary member such as a plate or by adhering to a light transmission plate 11 such as glass or resin. Moreover, it is good also as a structure which inserts the light transmissive board 11 in the frame integrally molded.

そうして作られた太陽電池モジュールの発電電力を用いて、家屋やビルの照明や電動機等の負荷を稼動させる。このとき、太陽電池モジュール２０のみでは屋根上や地上に固定設置できないことから、図１４に示すように、太陽電池モジュール２０を架台と呼ばれる鉄やアルミニウムなどのレールを組合わせた設置架台に載せて固定し、太陽光発電装置Ｊとするのであるが、太陽光発電装置Ｊは風などの風加重により飛ばされたり転倒させられたりしないように、架台の基部に基礎３１と呼ばれるコンクリート塊などの重量物を埋設したものや、埋設はせずにコンクリート塊などの重量物を設置面に設けてその重量によって風荷重に対抗する置き基礎や、コンクリートやレンガなどの設置面にアンカーなどを打ち込むなどして強固に固定するため、一旦設置してしまうと容易に方位を変えることができない。また、架台は基礎３１間を渡す底部レール３２、太陽電池モジュール２０を固定する上部レール３３、太陽電池モジュール２０を支持するとともに傾斜角をつくる短辺レール３４、長辺レール３５のように複数のレールがボルト等で締め付け固定されているので、組立て工数が多く、また、一旦締め付け固定してしまうと太陽の高さに合わせて傾斜角度を容易に変更することができない。また、設置場所の移設も容易でない。   Loads such as lighting of houses and buildings, electric motors and the like are operated using the generated power of the solar cell module thus produced. At this time, since the solar cell module 20 alone cannot be fixedly installed on the roof or on the ground, as shown in FIG. 14, the solar cell module 20 is mounted on an installation frame called a frame that is a combination of rails such as iron and aluminum. The solar power generation device J is fixed, and the solar power generation device J has a weight such as a concrete lump called the foundation 31 at the base of the pedestal so that it is not blown or overturned by wind load such as wind. Do not embed objects or install heavy objects such as concrete blocks on the installation surface without embedding them, and place anchors on the installation surface such as concrete and bricks, etc. Therefore, once installed, the orientation cannot be easily changed. The gantry includes a bottom rail 32 that passes between the foundations 31, an upper rail 33 that fixes the solar cell module 20, a short side rail 34 that supports the solar cell module 20 and creates an inclination angle, and a long side rail 35. Since the rails are fastened and fixed with bolts or the like, the number of assembling steps is large, and once they are fastened and fixed, the inclination angle cannot be easily changed in accordance with the height of the sun. In addition, it is not easy to move the installation location.

また、特に住宅の陸屋根の構造としては、建造物の構造体であるコンクリート部の上に防水層を設け、さらにその上に押えコンクリートと呼ばれるコンクリート層を形成することで、防水層を保護すると同時に防水層の浮き上がりを押さえる構造が一般的に採用されている。   In particular, as the structure of a flat roof of a house, a waterproof layer is provided on the concrete part that is the structure of the building, and a concrete layer called presser concrete is formed on the waterproof layer, thereby simultaneously protecting the waterproof layer. A structure that suppresses the floating of the waterproof layer is generally employed.

図１２は従来の押えコンクリートを用いた屋根上に太陽光発電装置をアンカーボルトを用いて設置する様子を模式的に説明する概略断面図である。   FIG. 12 is a schematic cross-sectional view schematically illustrating a state in which a photovoltaic power generation apparatus is installed on a roof using conventional presser concrete using anchor bolts.

従来、特に既築の陸屋根に前述の太陽光発電システムを設置する場合には、図１２に示すように押えコンクリート３を部分的に切除し、防水層４２を貫通して建造物構造体４３に鉄筋４４を固定し、鉄筋４４の外部をコーキング材４５で防水仕上げし、さらに基礎コンクリート４６を成型したのち、モルタル４７で外周部を仕上げ、ケミカルアンカー４８を基礎コンクリートの上部に固定して、しかるのちベースレール４９をケミカルアンカー４８に固定し、ベースレール４９上に太陽電池モジュール２０を固定するという構造が一般的である。   Conventionally, when the above-described photovoltaic power generation system is installed particularly on an existing flat roof, the presser concrete 3 is partially excised as shown in FIG. The reinforcing bar 44 is fixed, the exterior of the reinforcing bar 44 is waterproofed with a caulking material 45, the foundation concrete 46 is molded, the outer periphery is finished with a mortar 47, and the chemical anchor 48 is fixed to the upper part of the foundation concrete. After that, a structure in which the base rail 49 is fixed to the chemical anchor 48 and the solar cell module 20 is fixed on the base rail 49 is general.

また、上記方法と比べて部材や施工工数を削減できる方法として、底部レールと上部レール、短辺レールと長辺レールを無くし、複数個の固定用金具のみを用いて基礎部材に太陽電池モジュールを固定し、しかも傾斜角度を自在に設定することができる方法も提案されている。（特許文献１参照）。
特開２００３−１８４２３５公報 Moreover, as a method that can reduce the number of members and construction man-hours compared to the above method, the bottom rail and the top rail, the short side rail and the long side rail are eliminated, and the solar cell module is attached to the base member using only a plurality of fixing brackets. There has also been proposed a method in which the inclination angle can be set freely. (See Patent Document 1).
JP 2003-184235 A

しかしながら、前述の設置方法においては、基礎の製作に部材・工事期間がかかるという問題と、施工前に現場の状況を正確に把握し基礎や太陽電池モジュール固定架台を個別設計しなければならないという問題があった。また、基礎数を低減するために太陽電池モジュールを縦横に複数枚連結するという工法が一般的であったため、設置エリアの形状に自由度が少なかった。   However, in the installation method described above, there are problems that it takes materials and construction time to manufacture the foundation, and problems that the foundation and the solar cell module fixed mount must be individually designed by accurately grasping the situation at the site before construction. was there. Further, since a construction method of connecting a plurality of solar cell modules vertically and horizontally in order to reduce the number of foundations, the degree of freedom in the shape of the installation area was small.

また、通常押えコンクリートを用いる場合には、温度変化による押えコンクリートの膨張収縮によって防水層が破損しないように、押えコンクリートには３ｍピッチで縦横に、防水層に達する深さの伸縮目地を設けなければならず、必ずしも太陽電池モジュールを固定するアンカーボルトの位置に押えコンクリートの継ぎ目が来ないとは限らない。また、押えコンクリートの端部近くではアンカーボルトが加わる応力に耐えられず押えコンクリートが欠けてアンカーボルトが脱落するケースもある。このように固定用金具を押えコンクリートに直接アンカーボルトなどで固定する場合には、現場で簡単に固定点位置を変更でき、伸縮目地や鉄筋を避けることのできる構造が必要となる。   In addition, when using normal presser concrete, the presser concrete must be provided with stretchable joints that reach the waterproof layer vertically and horizontally at a pitch of 3 m so that the waterproof layer will not be damaged by expansion and contraction of the presser concrete due to temperature changes. It is not always necessary to place the presser concrete joint at the position of the anchor bolt for fixing the solar cell module. In some cases, near the end of the presser concrete, the anchor bolt cannot withstand the stress applied by the anchor bolt and the presser concrete is chipped and the anchor bolt falls off. In this way, when the fixing bracket is directly fixed to the holding concrete with an anchor bolt or the like, a structure that can easily change the position of the fixing point on the site and avoid the expansion joint and the reinforcing bar is required.

この問題に対しては、特許文献１においても太陽電池モジュール枠に固定用金具がボルト等で定位置に固定されるため、取り付け位置の変更には再度ネジ穴等を開け直さなくてはない。また、支持支柱の角度を変えて対応した場合にはアンカーボルトを傾斜して打ち込むなどしなくてはならず、基礎などへの固定点位置を調整しにくく、また、対応についての記述もなされていない。   With respect to this problem, also in Patent Document 1, since the fixing bracket is fixed to the solar cell module frame at a fixed position with a bolt or the like, the screw hole or the like must be reopened to change the mounting position. In addition, when responding by changing the angle of the support column, it is necessary to tilt the anchor bolt and drive it in, it is difficult to adjust the position of the fixed point on the foundation etc., and there is also a description about the response. Absent.

また、特許文献１において固定用金具は方向と角度を可変できるとされているが、その目的は太陽電池モジュールを前後左右に傾斜させることに対応するものであり、設置面に対する固定用金具の位置移動については何ら述べられていないのである。   Further, in Patent Document 1, it is said that the direction and angle of the fixing bracket can be varied, but the purpose corresponds to tilting the solar cell module back and forth and right and left, and the position of the fixing bracket with respect to the installation surface There is no mention of movement.

また、固定用金具と太陽電池モジュールの固定方法についてはネジ止め以外には述べられておらず、積雪による正圧や、風による正・負圧が太陽電池モジュールに働いた場合に、太陽電池モジュールの枠体によって全ての荷重に対抗しなければならず、太陽電池モジュールの光透過板である強化ガラスの湾曲に伴って枠部が外側に広がり強化ガラスが枠から脱離することで、太陽電池モジュールの破損を招くという問題がある。   In addition, there is no mention of fixing the fixing bracket and the solar cell module other than screwing, and when the positive pressure due to snow or the positive / negative pressure due to wind acts on the solar cell module, the solar cell module The solar cell module must be able to resist all loads by the frame of the solar cell module by spreading the tempered glass from the frame with the frame portion extending outwards as the light-transmitting plate of the solar cell module is bent. There is a problem of causing damage to the module.

そこで、本発明は従来の上述した諸問題に鑑み案出されたものであり、設置面の状況にあわせて太陽電池モジュールの位置を変更せずに固定用金具を設置でき、積雪や風による応力への抵抗力を損なうことなく、現場で簡単に固定位置を調整しながら押えコンクリート等の設置面に固定することが可能で、基礎部材と基礎製作工事を大幅に低減した太陽光発電装置を提供することが目的である。   Therefore, the present invention has been devised in view of the above-described problems, and can be used to install a fixing bracket without changing the position of the solar cell module in accordance with the situation of the installation surface. Provides a photovoltaic power generation device that can be fixed to the installation surface of the presser foot concrete while adjusting the fixing position easily without sacrificing resistance to the base, and that significantly reduces the foundation materials and foundation manufacturing work. The purpose is to do.

さらに、本発明の他の太陽光発電装置は、前記設置固定部材の設置固定位置は、前記支持脚部を中心として板状部の先端まで距離を半径とする円内領域内の任意箇所に可変できることを特徴とする。   Furthermore, in another photovoltaic power generation apparatus according to the present invention, the installation fixing position of the installation fixing member can be changed to an arbitrary position in an in-circle region having a radius from the support leg portion to the tip of the plate-like portion. It is possible to do.

以下に、本発明に係る太陽光発電装置の一実施形態について、住宅の陸屋根上に設置する場合を例に取り、模式的に示した図に基づいて詳細に説明する。   Hereinafter, an embodiment of the photovoltaic power generation apparatus according to the present invention will be described in detail based on a diagram schematically showing a case where the photovoltaic power generation apparatus is installed on a flat roof of a house.

FIG. 5 is a perspective view schematically showing a fixing position changing method using an L-shaped installation bracket of the fixing bracket of the photovoltaic power generation apparatus according to the present invention.

図１に示すように本発明の太陽光発電装置Ｓは、枠体を有する太陽電池モジュール２０と、住宅の陸屋根や地上に敷設されたコンクリートやレンガに代表されるような硬質部材３と、この硬質部材３上にアンカーボルト等で固定されるとともに太陽電池モジュールを載置・固定する固定用金具２（２ａ、２ｂ）とから成る。なお、設置面はコンクリートを用いることにより太陽電池モジュールを強固に設置面に固定することができるため、本例では硬質部材３を屋根材として用いられている押えコンクリートであるとして説明する。   As shown in FIG. 1, the photovoltaic power generation device S of the present invention includes a solar cell module 20 having a frame, a hard member 3 typified by concrete or brick laid on a flat roof of a house or the ground, It consists of fixing metal fittings 2 (2a, 2b) which are fixed on the hard member 3 with anchor bolts or the like and on which the solar cell module is placed and fixed. In addition, since a solar cell module can be firmly fixed to an installation surface by using concrete for an installation surface, in this example, the hard member 3 is demonstrated as the pressing concrete used as a roofing material.

図２に示すように、住宅の屋根上に設けられた防水層１９上には押えコンクリート３が配されている。固定用金具２（２ａ、２ｂ）はＬ字状設置金具６と受け金具７と押え金具８が締結部材９（９ａ、９ｂ）で締結された構成であり、Ｌ字状設置金具６は設置面に固定するための底板部７３と受け金具７を支えるための直立部７１を有する。Ｌ字状設置金具６の底板部７３は押えコンクリート３にアンカー４で固定される。このとき、アンカー４が押えコンクリート３を突き抜けて防水層１９に達してしまうと屋根の防水性が損なわれるので、アンカーボルト４の長さは防水層１９に達しないように選択する。固定用金具２（２ａ、２ｂ）の受け金具７はＬ字状設置金具６に固定するための支持脚部７２を含む。固定用金具２（２ａ、２ｂ）の受け金具７ａおよび７ｂ間には太陽電池モジュール２０が載置され、押え金具８を締結部材９ａで受け金具７（７ａ、７ｂ）に締結固定することで前記太陽電池モジュール２０の枠部１８が受け金具７（７ａ、７ｂ）と押え金具８によって挟持固定される。   As shown in FIG. 2, presser concrete 3 is disposed on a waterproof layer 19 provided on the roof of the house. The fixing bracket 2 (2a, 2b) has a configuration in which an L-shaped mounting bracket 6, a receiving bracket 7, and a presser bracket 8 are fastened by fastening members 9 (9a, 9b). A bottom plate portion 73 for fixing to the metal plate and an upright portion 71 for supporting the metal fitting 7. The bottom plate portion 73 of the L-shaped installation fitting 6 is fixed to the presser concrete 3 with the anchor 4. At this time, if the anchor 4 penetrates the presser concrete 3 and reaches the waterproof layer 19, the waterproof property of the roof is impaired. Therefore, the length of the anchor bolt 4 is selected so as not to reach the waterproof layer 19. The receiving bracket 7 of the fixing bracket 2 (2a, 2b) includes a support leg 72 for fixing to the L-shaped installation bracket 6. The solar cell module 20 is placed between the receiving brackets 7a and 7b of the fixing bracket 2 (2a, 2b), and the holding bracket 8 is fastened and fixed to the receiving bracket 7 (7a, 7b) by the fastening member 9a. The frame portion 18 of the solar cell module 20 is sandwiched and fixed by the receiving metal fittings 7 (7a, 7b) and the holding metal fittings 8.

次に太陽光発電装置が設置される様子を説明する。   Next, how the solar power generation apparatus is installed will be described.

図３（ａ）に示すように、まず、押えコンクリート３に下穴５０を開けた上で、Ｌ字状設置金具６の底板部７３に開けられた貫通穴６１を介してアンカーボルト４で固定する。そして図３（ｂ）に示すようにＬ字状設置金具６の直立部７１に受け金具７（７ａ、７ｂ）の支持脚部７２（７２ａ、７２ｂ）を締結部材９ｂで締結する。最後に図３（ｃ）に示すように受け金具７（７ａ、７ｂ）の上部に太陽電池モジュール２０の枠部１８を載置し、押え金具８を締結部材９ａで締結することにより太陽電池モジュール２０は受け金具７と押え金具８に挟まれる形で挟持固定される。これにより太陽電池モジュール２０の枠部１８は、外側に膨らんだり固定用金具２に対してねじれたりすることなく固定される。   As shown in FIG. 3 (a), first, a pilot hole 50 is formed in the presser concrete 3, and then fixed with an anchor bolt 4 through a through hole 61 formed in the bottom plate portion 73 of the L-shaped installation bracket 6. To do. And as shown in FIG.3 (b), the support leg part 72 (72a, 72b) of the receiving metal fitting 7 (7a, 7b) is fastened to the upright part 71 of the L-shaped installation metal fitting 6 by the fastening member 9b. Finally, as shown in FIG. 3C, the frame portion 18 of the solar cell module 20 is placed on the upper portion of the receiving metal fitting 7 (7a, 7b), and the holding metal fitting 8 is fastened by the fastening member 9a, thereby the solar cell module. 20 is clamped and fixed in such a manner as to be sandwiched between the receiving metal 7 and the holding metal 8. Thereby, the frame part 18 of the solar cell module 20 is fixed without bulging outward or being twisted with respect to the fixing bracket 2.

なお、図中では受け金具７は長さの短い受け金具７ａと長さの長い受け金具７ｂを用いて太陽電池モジュール２０に傾斜を持たせるようにしているが、両方を同じ長さにして水平設置としたり、設置面である押えコンクリート３が傾斜しているのであればその傾斜角度を利用するのでもよい。   In addition, although the receiving metal fitting 7 is made to incline the solar cell module 20 using the short receiving metal fitting 7a and the long receiving metal fitting 7b in the figure, both are made the same length and horizontal. If the presser concrete 3 that is the installation surface is inclined, the inclination angle may be used.

また、固定用金具２（２ａ、２ｂ）を仮組みした上でアンカーボルト４で固定したり、太陽電池モジュール２０を挟持固定した状態でアンカーボルト４で固定し、墨出しを行わなくてよいようにするなどしてもよく、施工の手順は状況に応じて選択することが可能である。   In addition, the fixing bracket 2 (2a, 2b) is temporarily assembled and then fixed with the anchor bolt 4, or the solar battery module 20 is clamped and fixed with the anchor bolt 4 so as not to perform ink marking. The construction procedure can be selected according to the situation.

このように、本発明の太陽光発電装置によれば太陽電池モジュールを個々に設置することができるので、太陽電池モジュールを設置するだけの面積があれば設置が可能であり、途中に設置物等の障害物があってもそこだけ設置しなければよいのであって、従来、太陽電池モジュールを縦横に複数枚連結する工法では複数の太陽電池モジュールを共通のレール上に載置するために途中に障害物があれば設置できず、設置エリアの形状に自由度が少ないといった問題を解決する。また、個々を小規模な構成とすることで基礎が無くても設置面の強度のみで対応可能とし、部品点数と基礎製作工数の削減とできる。   As described above, according to the photovoltaic power generation apparatus of the present invention, the solar cell modules can be individually installed. Therefore, if there is an area sufficient to install the solar cell modules, the solar cell modules can be installed, and the installation object or the like is provided in the middle In the conventional method of connecting a plurality of solar cell modules vertically and horizontally, it is necessary to install a plurality of solar cell modules on a common rail. It solves the problem that it cannot be installed if there are obstacles, and the shape of the installation area is less flexible. In addition, by making each small-scale configuration, even if there is no foundation, it is possible to cope with only the strength of the installation surface, and it is possible to reduce the number of parts and the number of foundation manufacturing steps.

一方、図４に示すように、通常押えコンクリートを屋根材として用いる場合には、温度変化による押えコンクリートの膨張収縮によって先に述べた防水層が破損しないように、押えコンクリート３ａ、３ｂ間に例えば３ｍピッチで縦横に、防水層に達する深さの伸縮目地３０（３０ａ、３０ｂ）を設けているため、図中のように必ずしも太陽電池モジュール２０を固定する固定用金具２のアンカーボルトの打ち込み位置であるＬ字状設置金具６に押えコンクリート３の継ぎ目が来ないとは限らない。また、押えコンクリート３の端部近くでは打ち込まれたアンカーボルトによって加わる応力に対し押えコンクリート３の耐久力が劣るため、ひび割れや欠けが生じてアンカーボルトが脱落する場合がある。よって、このように固定用金具２を押えコンクリート３に直接アンカーボルトなどで固定する場合には、現場で簡単に固定点位置を変更でき、伸縮目地３０ａを避けることのできる構造が必要となる。そこで本発明の固定構造は、固定用金具２のＬ字状設置金具６に伸縮目地３０ａなどの阻害要因が横方向に存在している場合は、一旦締結部材９ｂをはずしてＬ字状設置金具６を取り外し、図５に示すようにＬ字状設置金具６の差込み方向を１８０度回転させ、Ｌ字状設置金具６のアンカーボルト打ち込み位置を押えコンクリート３ｂの内側に移動させた上でアンカーボルト４で固定する。このように伸縮目地３０などの阻害要因を避けてアンカーボルト４を固定することが可能である。   On the other hand, as shown in FIG. 4, in the case of using normal presser concrete as a roofing material, for example, between the presser concretes 3 a and 3 b so that the waterproof layer described above is not damaged by expansion and contraction of the presser concrete due to temperature change. Since the expansion joints 30 (30a, 30b) having a depth reaching the waterproof layer are provided vertically and horizontally at a pitch of 3 m, the anchor bolt driving position of the fixing bracket 2 for fixing the solar cell module 20 as shown in the figure is necessarily provided. The joint of the presser concrete 3 does not necessarily come to the L-shaped installation bracket 6. Moreover, since the durability of the presser concrete 3 is inferior to the stress applied by the anchor bolts that have been driven in near the end of the presser concrete 3, cracks and chips may occur and the anchor bolts may fall off. Therefore, when the fixing bracket 2 is fixed directly to the holding concrete 3 with an anchor bolt or the like in this way, a structure that can easily change the fixing point position on the site and avoid the expansion joint 30a is required. Therefore, in the fixing structure of the present invention, when an obstruction such as the expansion joint 30a exists in the lateral direction in the L-shaped mounting bracket 6 of the fixing bracket 2, the fastening member 9b is once removed and the L-shaped mounting bracket. 6 is removed, the insertion direction of the L-shaped mounting bracket 6 is rotated 180 degrees as shown in FIG. 5, and the anchor bolt driving position of the L-shaped mounting bracket 6 is moved to the inside of the holding concrete 3b, and then the anchor bolt Fix with 4. In this way, it is possible to fix the anchor bolt 4 while avoiding obstruction factors such as the expansion joint 30.

FIG. 8 is a perspective view schematically showing a step between adjacent solar power generation devices in a solar power generation apparatus according to the present invention, and FIG. 9 is a main view. It is a perspective view which shows typically the fixing height change method by the receiving metal fitting of the fixing metal fitting of a solar power generation device which concerns on invention, and an L-shaped installation metal fitting.

また、図６に示すように、アンカーボルトの打ち込み位置であるＬ字状設置金具６の下に押えコンクリート３（３ａ、３ｂ）間の伸縮目地３０ｂのように阻害要因が縦方向に存在して固定できない場合は、一旦締結部材９ａを緩めて押え金具材８と受け金具７による太陽電池モジュール２０の挟持固定を解除し、図７に示すように固定用金具２を図中矢印のように太陽電池モジュール２０の枠部１８に沿って位置変更することで、伸縮目地３０ｂなどの阻害要因を避けてアンカーボルト４を押えコンクリート３ｂに固定することが可能である。   Further, as shown in FIG. 6, there are vertical obstructions in the vertical direction, such as an expansion joint 30b between the presser concretes 3 (3a, 3b) under the L-shaped installation bracket 6 where the anchor bolt is driven. If it cannot be fixed, the fastening member 9a is once loosened to release the holding and fixing of the solar cell module 20 by the holding metal member 8 and the receiving metal member 7, and the fixing metal 2 as shown by the arrow in FIG. By changing the position along the frame portion 18 of the battery module 20, it is possible to avoid the obstruction factors such as the expansion joint 30b and fix the anchor bolt 4 to the holding concrete 3b.

また、屋根面の段差、凹凸、経年変化によって生じる屋根上の歪みなどによって、図８に示すように太陽電池モジュール２０ａと隣接する太陽電池モジュール２０ｂとの間に高さの差が生じている場合に対応させることもできる。具体的には、固定用金具２のＬ字状設置金具６の直立部７１と受け金具７の支持脚部７２の締結部材９ｂを通す貫通穴５を縦長の長穴としておき、図９に示すように前記締結部９ｂを緩めて受け金具７とＬ字状設置金具６の貫通穴５を利用して太陽電池モジュール２０ａの高さを調整し、ふたたび締結部材９ｂを締めなおすことで、太陽電池モジュール２０ｂとの高さあわせを行うことが可能となる。   In addition, when there is a difference in height between the solar cell module 20a and the adjacent solar cell module 20b as shown in FIG. 8 due to a step on the roof surface, unevenness, distortion on the roof caused by secular change, and the like. It can be made to correspond to. Specifically, the through hole 5 through which the fastening member 9b of the upright part 71 of the L-shaped installation metal fitting 6 of the fixing metal fitting 2 and the support leg 72 of the receiving metal piece 7 passes is formed as a vertically long elongated hole, as shown in FIG. As described above, the fastening portion 9b is loosened, the height of the solar cell module 20a is adjusted using the through-hole 5 of the receiving metal 7 and the L-shaped installation metal 6, and the fastening member 9b is retightened to re-tighten the solar cell. It is possible to perform height adjustment with the module 20b.

また、上記締結部材用長穴は略垂直方向に伸びる長穴と該長穴から略水平方向に延びる複数の保持用延出穴を有することで、より確実に太陽電池モジュールを略水平もしくは意図した角度に傾斜設置することができる。   Further, the elongated hole for the fastening member has an elongated hole extending in a substantially vertical direction and a plurality of holding extending holes extending in a substantially horizontal direction from the elongated hole, so that the solar cell module is substantially horizontal or intended more reliably. Can be installed at an angle.

図１０は本発明に係る太陽光発電装置の他の第一の実施形態を模式的に説明する斜視図、図１１は本発明に係る太陽光発電装置の他の第一の実施形態を模式的に説明する斜視図である。   FIG. 10 is a perspective view schematically illustrating another first embodiment of the photovoltaic power generation apparatus according to the present invention, and FIG. 11 schematically illustrates another first embodiment of the photovoltaic power generation apparatus according to the present invention. FIG.

また、上述したように固定用金具の押え金具と受け金具によって太陽電池モジュールを挟持固定する支持構造であり、太陽電池モジュールの枠部上のどこにでも取り付けが可能であるので、図１０に示すように、大型の太陽電池モジュール２０ｃの中央部のたわみ防止や、風荷重などの外力にたいする耐性をさらに強くさせたい場合には、固定用金具２（２ａ、２ｂ）を増設し耐荷重強度を増やすだけでよいので、特別な固定用金具を用いなくてよく汎用性に富む。   Further, as described above, the support structure is such that the solar cell module is sandwiched and fixed by the holding metal fitting and the receiving metal fitting, and can be attached anywhere on the frame portion of the solar cell module. In addition, when it is desired to further prevent the deflection of the central portion of the large-sized solar cell module 20c and to further enhance the resistance to external forces such as wind load, the fixing bracket 2 (2a, 2b) is added to increase the load bearing strength. Therefore, there is no need to use a special fixing bracket, which is versatile.

また、図中では固定用金具２（２ａ、２ｂ）は太陽電池モジュール２０の底辺と上辺の２辺のみに配しているが、先に述べた固定用金具２の高さ方向の伸縮機能を併用すれば前記底辺と上辺だけでなく傾斜している辺にも配して３〜４辺支持とすることも可能であり、縦長や横長の太陽電池モジュールであっても、どの方位へ向けても十分な強度で支持固定することができる。   Further, in the drawing, the fixing brackets 2 (2a, 2b) are arranged only on the bottom side and the top side of the solar cell module 20, but the above-described expansion / contraction function in the height direction of the fixing bracket 2 is provided. If used in combination, it is possible to support not only the bottom and top sides but also the inclined sides to support 3 to 4 sides, and in any orientation, even for vertically or horizontally long solar cell modules Can be supported and fixed with sufficient strength.

それとは別に、固定用金具２の数量を増やさずに太陽電池モジュールを十分な強度で支持固定する方法を図１１に示す。固定用金具２ａと２ｂの間に補強レール１７を渡し、脱落しないようにねじやボルトや接着によって固定し、前記補強レール１７上に太陽電池モジュール２０を載置する。このようにすることで、太陽電池モジュール２０が大型の太陽電池モジュールや枠体の強度の強くないものであっても、固定用金具２（２ａ、２ｂ）は横方向に移動可能であるので、補助レール１７による太陽電池モジュール２０の支持位置を端部付近でも中央付近でも自由に設定でき、太陽電池モジュール２０の枠体の中央付近を補強レール１７が支持するようにして太陽電池モジュール２０の自重によるたわみを生じさせないようにできる。また、外力に対する抵抗力も向上させることができる。   Apart from that, FIG. 11 shows a method of supporting and fixing the solar cell module with sufficient strength without increasing the number of the fixing brackets 2. The reinforcing rail 17 is passed between the fixing metal fittings 2a and 2b, and is fixed by screws, bolts, or adhesion so as not to drop off, and the solar cell module 20 is placed on the reinforcing rail 17. By doing in this way, even if the solar cell module 20 is a large-sized solar cell module or a frame whose strength is not strong, the fixing bracket 2 (2a, 2b) can move in the lateral direction, The supporting position of the solar cell module 20 by the auxiliary rail 17 can be freely set near the end portion or near the center, and the reinforcing rail 17 supports the vicinity of the center of the frame of the solar cell module 20 so that the weight of the solar cell module 20 can be reduced. It is possible to prevent the bending due to. Moreover, the resistance force with respect to an external force can also be improved.

以上詳述したが、太陽電池モジュールの挟持固定はボルトを使用するだけではなく、バネ等を用いたものとしてもかまわない。   As described above in detail, the solar cell module may be clamped and fixed not only using bolts but also using springs or the like.

また、固定する対象は押えコンクリートだけではなく、別途準備したコンクリート部材や金属部材などであっても対応可能であり、Ｌ字状設置金具６のアンカーボルト打ち込み部分の形状を最適化して、板金屋根・傾斜屋根・地面などに固定することもできる。   In addition, the object to be fixed is not limited to the presser concrete, but can be a concrete member or a metal member prepared separately, and the shape of the anchor bolt driving portion of the L-shaped mounting bracket 6 is optimized to make a sheet metal roof. -It can be fixed to an inclined roof or the ground.

また、Ｌ字状設置金具６を固定する部材としてアンカーボルト４を例示しているが、ケミカルアンカー・コンクリートビスなどの他の締結手段であってもよい。   Moreover, although the anchor bolt 4 is illustrated as a member which fixes the L-shaped installation metal fitting 6, other fastening means, such as a chemical anchor and a concrete screw, may be sufficient.
