Description

【0001】
【発明の属する技術分野】
本発明は、太陽光利用機器(太陽電池モジュール等の太陽電池装置や太陽熱集熱器)などの平板状をなす設置体を、架台に好適に設置することが可能な固定装置及びそれを用いた太陽光利用装置に関するものである。
【0002】
【従来の技術とその課題】
太陽光利用機器用の固定装置は、例えば太陽電池や太陽熱集熱器をはじめとする様々な屋根設置体を、地上や屋根上、ビルの屋上などに、設置架台を用いて固定するためのものである。この設置架台には、家屋などの屋根上に縦材、横材を配して太陽光利用機器を平面上に設置するものや、太陽光をより効率的に受ける為に縦材を傾斜させたものがあり、用途や目的によって形状は様々である。
【0003】
例えば、図8に示すように、太陽電池モジュール20を複数枚組み合わせて太陽電池アレイとする太陽電池システムJは、地面や屋根などに設置する横材6上に、それに対して直交するように縦材5を配して架台を構成し、縦材5に太陽電池モジュール20をボルト等で固定する。縦材5は横材6に直接取り付けてもよいが、太陽電池モジュール20が太陽光をより多く受けて発電できるように太陽に向けて傾斜を持たせるのが望ましい。そこで、横材6と縦材5の間に、長さの異なる脚材8a、8bを設けて架台に傾斜をつけるのが一般的である。なお、脚材8a、8bと横材6の間には固定金具7が組みつけられており、脚材8a、8bが太陽電池アレイを支えるのに適した角度で取り付けられるようにしている。
【0004】
また、横材6上に直接縦材5を配する場合、屋根や壁面に沿った状態で設置できるので外観が薄く、屋根との一体感が得やすい。また、太陽電池モジュール背面への風の回りこみが生じにくい。
【0005】
しかしながら、台風時や突風時などにおいて、構造建築物の上などでは強い風が太陽電池モジュールの背面に回りこみ、その風圧によって太陽電池モジュールを縦材に固定しているボルトや太陽電池モジュールのフレームにストレスがかかる。
【0006】
図9(a)に示すように、太陽電池モジュール20はアルミニウムやステンレスからなるフレーム10部に設けた取り付け穴によって、縦材5にボルト、ナットなどの締結部材11で締結されている。しかし、太陽電池モジュール20の背面から押し上げる力が加わると、図9(b)に示すようにフレーム10のねじ穴の周囲が変形し、遂には太陽電池モジュール20が脱落する。このため、背面からの風圧に対抗できるように太陽電池モジュール20のフレーム10の厚みを厚くしたり、材質を強固なものに変更する。あるいは、フレー10の断面形状の強化といった対策がとられるが、厚みの増えた分や材質変更による重量増加、断面形状の複雑化によるフレーム金型の製作工数の増加といった問題がある。
【0007】
また、図10に示すように、耐風圧性を持たせるために、バックパネル13を用いて太陽電池モジュール20に直接応力が加わらないようにすることで、太陽電池モジュール20の汎用性を維持する方法もあるが、この場合もバックパネル13が別部品として必要なことと、バックパネル13に強度が要求されるため重量増加に繋がり、その重量を支えるために横材、縦材、脚材の強度を向上させなくてはならないことも生じる。
【0008】
また、図11に示すように、太陽電池モジュール20を押えプレート14を縦材5に締め付けることで強固に固定することができるが、締め付けすぎによる太陽電池モジュール20のフレームの潰れや、例えば押えプレート14が雪止めとなってしまい、積雪滞留による発電不足や凍結による破損を招くことも生じる。
【0009】
そこで、本発明は上述の諸事情に鑑みてなされたものであり、太陽光利用機器の設置作業が容易で、しかも強度を上げる為の特別な加工を必要とせず、しかも簡単且つ確実に固定するための固定装置を提供することを目的とする。
【0010】
【課題を解決するための手段】
上記目的を達成するために、本発明の固定装置は、平板状の太陽光利用機器の複数を並設する際に、隣合う2つの太陽光利用機器の間に設ける固定装置であって、前記2つの太陽光利用機器の上方への動きを禁止する上折り曲げ部と、前記2つの太陽光利用機器の下方への動きを禁止する下折り曲げ部とを備えてなることを特徴とする。また特に、前記上折り曲げ部及び下折り曲げ部の少なくとも一方は、互いに逆方向に折り曲げられた折り曲げ部を備えることとする。
【0011】
また、本発明の太陽光利用装置は、設置台に平板状の太陽光利用機器の複数を並設してなり、隣合う2つの太陽光利用機器の間に上記構成の固定装置を設けたことを特徴とする。また特に、前記太陽光利用機器が太陽電池または太陽熱集熱器であることとする。
【0012】
【発明の実施の形態】
以下、本発明の実施形態を平板状の太陽光利用機器を設置架台上に配設する場合を例にとり、模式的に図示した図面に基づいて詳細に説明する。図1に本発明の太陽光利用機器用の固定装置Kの斜視図を、図2にその設置例の斜視図を、図3(a)、(b)に設置方法の断面図を示す。
【0013】
図1に示すように、本発明の固定装置Kは、太陽電池モジュール等の太陽電池または太陽熱集熱器である平板状の太陽光利用機器の複数を並設する際に、隣合う2つの太陽光利用機器の間に設けるものであって、前記2つの太陽光利用機器の上方への動きを禁止する上折り曲げ部(第1折り曲げ部1、第3折り曲げ部3)と、前記2つの太陽光利用機器の下方への動きを禁止する下折り曲げ部(第2折り曲げ部2、第4折り曲げ部4)とを備えてなる。また、前記上折り曲げ部及び下折り曲げ部の少なくとも一方は、互いに逆方向に折り曲げられた折り曲げ部を備えている。
【0014】
また、本発明の太陽光利用装置は、設置台に平板状の太陽光利用機器の複数を並設してなるものであり、隣合う2つの太陽光利用機器の間に上記固定装置Kを設けたものである。そして特に、前記太陽光利用機器が太陽電池または太陽熱集熱器であることを特徴とする。
【0015】
すなわち、固定装置Kは、太陽光利用機器が上方への動きを抑える第1折り曲げ部1と、下方へ動くのを抑える第2折り曲げ部2と、これら折り曲げ部に対しそれぞれ逆方向に折り曲げられた第3折り曲げ部3及び第4折り曲げ部4を隣り合わせに形成されている。また、第2折り曲げ部2及び第4折り曲げ部4には、架台の縦材や横材及び/または太陽光利用機器とを固定するためのボルト類とナット類で締結させるための締結部9を備えている。
【0016】
このような固定装置Kを、図2に示すように縦材5上に配された、例えば複数の太陽電池モジュール20間に、太陽電池モジュール20を挟み込むように配され縦材5に締結される。固定装置Kは太陽電池モジュール20の一部を支えるのみであるので、小型化が容易である。
【0017】
ここで、固定装置Kは例えば鉄やステンレス、アルミニウム等の強度に優れた金属材料で構成される。また、耐候性に優れたポリカーボネートやエポキシなどの樹脂成型品でもよい。また、締結部9を通して設置架台と締結する締結部材はボルトやナットが望ましい。
【0018】
以下に、固定装置Kの固定が如何に行なわれるかについて、設置架台へ太陽電池モジュールを取り付ける場合を例にとり説明する。図3に示すように、固定装置Kは、第1折り曲げ部1と第4折り曲げ部4によって太陽電池モジュール20aの枠部材を挟み込み、締結部9を通して固定装置Kと太陽電池モジュール20の枠部材を縦材5上に締結させる。同様に、第3折り曲げ部3と第2折り曲げ部2によって太陽電池モジュール20bも縦材5上に締結させる。
【0019】
これにより、例えば太陽電池モジュール20aが太陽電池モジュール背面からの風圧に対して浮上しようとした場合、この浮上しようとする力は固定装置Kの第1折り曲げ部1が押さえることで抑えられ、太陽電池モジュール20aの枠部材の締結部には引き抜くような応力がかからないようにしている。また、第1折り曲げ部1を引き上げようとする力は、第2折り曲げ部2及び第4折り曲げ部4の締結部に分散されるので、締結部9にかかる応力を極力少なくして締結部材11の負担も軽減させている。同様に太陽電池モジュール20bの場合も、第3折り曲げ部3が太陽電池モジュール20bの浮上を抑え、第2折り曲げ部2及び第4折り曲げ部4の締結部により縦材5から外れないようにしている。
【0020】
また、第1折り曲げ部1及び第3折り曲げ部3のいずれもが第2折り曲げ部2及び第4折り曲げ部4によって縦材5に締結されていることにより、万一、第2折り曲げ部2または第4折り曲げ部4を締結する締結部材11が脱落したとしても、太陽電池モジュール20a、20bは脱落せずに保持される。さらに、締結部材11の両方が脱落した場合においても、第1折り曲げ部1及び第4折り曲げ部4、第3折り曲げ部3及び第2折り曲げ部2により太陽電池モジュール20が挟み込まれていることにより、一方が浮き上がろうとすると固定装置Kを通してもう一方を持ち上げることになり、太陽電池モジュール2枚分を持ち上げる風圧がなければ浮き上がらないので簡単に脱落せず安全性が向上する。
【0021】
また、固定装置Kによって太陽電池モジュール間に隙間が生じるので、風が抜けやすくなり耐風性能が増す。また、雨、雪などの排水性も良いので凍結による破損も生じにくい。
【0022】
さらに、太陽電池モジュールの枠部材が通常品のままでもよいので、強度を向上させるために肉厚の厚いものに変更して重量が増加したり、汎用性が失われることがなく、しかも輸送手段も汎用と同一でよい。
【0023】
しかしながら、台風時等において強い風圧がかかった場合、固定装置Kが十分な強度を持っていると、締結材11に引き抜き力が集中してしまい、最悪の場合はボルトが折れるなどの問題が生じる恐れがある。このような場合、締結材11の強度を向上させる方法が考えられるが、縦材5がC型やL字型であるならば、図4に示すように第2折り曲げ部2を横方向にも延出させ、さらに折り曲げ方向と正反対の方向へも延出させた固定装置K2を使用しても良い。これにより、図5に示すように、第2折り曲げ部2を縦材5の上面の裏側に配することによって、図6に示すように、太陽電池モジュール20a、20bが浮き上がろうとする力を第1折り曲げ部1及び第3折り曲げ部3で抑え、固定装置K2自身が引き抜かれようとする力は第2折り曲げ部2によって直接縦材5で支えることにより、締結部材11へかかる応力を軽減させることができる。なお、第2折り曲げ部2には締結部9が設けられている。
【0024】
かくして、太陽電池モジュール背面からの風圧に対して浮き上がろうとした場合、浮き上がる力は固定装置の第1折り曲げ部が押さえることで抑えられ、太陽電池モジュールの枠部材の締結部には引き抜くような応力がかからない。これにより、太陽電池モジュールの枠部材及びそれに類する部材の強度を上げなくてもよく、太陽電池モジュールの重量増加を回避できる。また、一方の太陽電池モジュールを縦材に締結する締結材が、固定装置を介してもう一方の太陽電池モジュールを支えているので、締結部材の一部が脱落しても太陽電池モジュールは脱落せずに保持され安全性が向上する。さらに、いずれかの太陽電池モジュールの固定ボルトが脱落しても、隣の太陽電池モジュールが支えるといった脱落止め効果と、太陽電池モジュールの中央付近のたわみを解消するものとすることが可能な優れた固定構造を提供できる。
【0025】
また、一方の太陽電池モジュールを縦材に締結する締結材が、固定装置を介してもう一方の太陽電池モジュールを支えているので、締結部材の一部が脱落しても太陽電池モジュールは脱落せずに保持され安全性が向上する。さらには固定装置によって太陽電池モジュール間に隙間が生じるので、風が抜けやすくなり耐風性能が増す。また、雨、雪などの排水性も良いので凍結による破損も生じにくい。
【0026】
また、太陽電池モジュールの枠部材が通常品のままでもよいので、強度を向上させるために肉厚の厚いものに変更して重量が増加したり、汎用性が失われることがなく、輸送手段も汎用と同じままでよい。
【0027】
また、太陽電池モジュールが浮上しようとする力を第1折り曲げ部及び第3折り曲げ部で抑え、固定装置自身が引き抜かれようとする力は第2折り曲げ部によって直接縦材で支えることにより、締結部材へかかる応力を軽減させることができる。
【0028】
さらに、締結部を太陽電池モジュールの枠部材との接触面に設けた固定装置を設置架台ではなく太陽電池モジュールの長辺枠に取り付けることにより、いずれかの太陽電池モジュールの固定ボルトが脱落しても、隣の太陽電池モジュールが支えるといった脱落止め効果と、太陽電池モジュールの中央付近のたわみを解消することなどが可能な優れた固定装置を提供できる。
【0029】
次に、本発明に係る固定装置の変形例について説明する。図7(a)に示すように、締結部9を上折り曲げ部と下折り曲げ部との間に設けた固定装置K3を、ボルト類等の締結部材11を介して、設置架台ではなく太陽電池モジュール20の長辺枠に取り付けるようにしてもよい。
【0030】
この場合、図7(b)に示すように固定装置K3を太陽電池モジュール20に取り付けるだけでも、いずれかの太陽電池モジュールの固定ボルトが脱落しても、隣の太陽電池モジュールが支えるといった脱落止め効果がある。また、太陽電池モジュールの長辺が比較的長いものでは、太陽電池モジュールの自重によって中央付近がたわむ現象が生じるので、縦材5に締結している固定装置K以外に前記固定装置K3を中間に配設すれば、隣り合う太陽電池モジュール同士が支えあう形となり中央付近のたわみを解消する。なお、端部に位置する太陽電池モジュールは支え合う太陽電池モジュールが存在しないので、補強プレート12などで枠部材を補強する。
【0031】
このように、太陽電池モジュールに特別な加工が必要なく、しかも太陽電池モジュール背面からの風圧に対する耐性を向上させるとともに、不慮の事故で締結部材が脱落しても太陽電池モジュールが簡単に脱落しづらい機構としている。
【0032】
なお、本実施形態では太陽光利用機器として主に太陽電池モジュールを例に説明したが、平板状の太陽熱集熱器等でも同様な作用・効果を期待することができ、本発明の要旨を逸脱しない範囲で適宜変更し実施が可能である。
【0033】
【発明の効果】
以上説明したように、本発明の固定装置及び太陽光利用装置によれば、隣合う2つの太陽光利用機器の上方への動きを禁止する上折り曲げ部と、前記2つの太陽光利用機器の下方への動きを禁止する下折り曲げ部とを備え、前記上折り曲げ部及び下折り曲げ部の少なくとも一方は、互いに逆方向に折り曲げられた折り曲げ部を備えるようにしたので、太陽光利用機器背面からの風圧に対して浮き上がろうとした場合、浮き上がる力は固定装置の上折り曲げ部の押さにより極力抑えられる。これにより、太陽光利用機器の強度を向上させることなくその重量増加を回避できる。また、上折り曲げ部を引き上げようとする力は、下折り曲げ部に分散させることが可能なので、下折り曲げ部にかかる応力を少なくすることができる。

TECHNICAL FIELD OF THE INVENTION
The present invention uses a fixing device capable of suitably installing a flat plate-like installation body such as a solar device (a solar cell device such as a solar cell module or a solar heat collector) on a gantry, and uses the fixing device. It relates to a solar utilization device.
[0002]
[Prior art and its problems]
A fixing device for solar equipment is used to fix various roof installation bodies, such as solar cells and solar heat collectors, on the ground, on the roof, on the roof of a building, etc. using an installation stand. It is. This installation base has a vertical member and a horizontal member on the roof of a house, etc., and installs solar equipment on a flat surface, and the vertical member is inclined to receive sunlight more efficiently. There are various shapes depending on the application and purpose.
[0003]
For example, as shown in FIG. 8, a solar cell system J in which a plurality of solar cell modules 20 are combined to form a solar cell array is provided on a horizontal member 6 installed on the ground, a roof, or the like, so as to be perpendicular to the vertical member. A frame is formed by arranging the members 5, and the solar cell module 20 is fixed to the vertical members 5 with bolts or the like. The vertical member 5 may be directly attached to the horizontal member 6, but it is preferable that the vertical member 5 be inclined toward the sun so that the solar cell module 20 can receive more sunlight and generate power. Therefore, it is common to provide the legs 8a and 8b having different lengths between the horizontal member 6 and the vertical member 5 to incline the gantry. A fixing bracket 7 is assembled between the leg members 8a, 8b and the horizontal member 6, so that the leg members 8a, 8b can be attached at an angle suitable for supporting the solar cell array.
[0004]
Further, when the vertical members 5 are arranged directly on the horizontal members 6, the vertical members 5 can be installed along the roof or the wall surface, so that the appearance is thin and a sense of unity with the roof is easily obtained. In addition, it is difficult for wind to flow to the back of the solar cell module.
[0005]
However, in the event of a typhoon or a gust, a strong wind flows over the back of the solar cell module on a structural building, etc., and the wind pressure secures the solar cell module to the vertical members or the frame of the solar cell module. Is stressed.
[0006]
As shown in FIG. 9A, the solar cell module 20 is fastened to the vertical member 5 by fastening members 11 such as bolts and nuts through mounting holes provided in a frame 10 made of aluminum or stainless steel. However, when a force that pushes up from the back surface of the solar cell module 20 is applied, the periphery of the screw hole of the frame 10 is deformed as shown in FIG. 9B, and the solar cell module 20 finally falls off. For this reason, the thickness of the frame 10 of the solar cell module 20 is increased or the material is changed to a stronger material so as to be able to resist the wind pressure from the back. Alternatively, countermeasures such as strengthening the cross-sectional shape of the frame 10 are taken. However, there are problems such as an increase in thickness due to an increase in thickness, an increase in weight due to a change in material, and an increase in man-hours for manufacturing a frame mold due to a complicated cross-sectional shape.
[0007]
In addition, as shown in FIG. 10, a method for maintaining versatility of the solar cell module 20 by using the back panel 13 to prevent direct stress from being applied to the solar cell module 20 in order to impart wind pressure resistance. However, also in this case, the back panel 13 is required as a separate part, and the strength of the back panel 13 is required, which leads to an increase in weight. In order to support the weight, the strength of the horizontal member, the vertical member, and the leg member is required. There is also a need to improve.
[0008]
Further, as shown in FIG. 11, the solar cell module 20 can be firmly fixed by tightening the holding plate 14 to the vertical member 5, but the frame of the solar cell module 20 is crushed due to excessive tightening, and for example, the holding plate 14 serves as a snow stopper, which may cause insufficient power generation due to snow accumulation and damage due to freezing.
[0009]
Therefore, the present invention has been made in view of the above-mentioned circumstances, and the installation work of the solar utilizing equipment is easy, and does not require special processing for increasing the strength, and is simply and securely fixed. It is an object to provide a fixing device for the.
[0010]

Further, the solar utilization device of the present invention has a plurality of flat solar utilization devices arranged side by side on an installation table, and the fixing device having the above configuration is provided between two adjacent sunlight utilization devices. It is characterized by. In particular, the solar utilization device is a solar cell or a solar heat collector.

Such a fixing device K is arranged on the vertical member 5 as shown in FIG. 2, for example, is arranged between the plurality of solar cell modules 20 so as to sandwich the solar cell module 20 and fastened to the vertical member 5. . Since the fixing device K only supports a part of the solar cell module 20, miniaturization is easy.
[0017]
Here, the fixing device K is made of a metal material having excellent strength such as iron, stainless steel, and aluminum. Further, a resin molded product such as polycarbonate or epoxy excellent in weather resistance may be used. The fastening member to be fastened to the installation base through the fastening portion 9 is preferably a bolt or a nut.
[0018]
Hereinafter, how the fixing device K is fixed will be described with reference to an example in which a solar cell module is mounted on an installation base. As shown in FIG. 3, the fixing device K sandwiches the frame member of the solar cell module 20 a between the first bent portion 1 and the fourth bent portion 4, and connects the fixing device K and the frame member of the solar cell module 20 through the fastening portion 9. Fastened on the vertical member 5. Similarly, the solar cell module 20 b is also fastened to the vertical member 5 by the third bent portion 3 and the second bent portion 2.
[0019]
Thus, for example, when the solar cell module 20a attempts to float with respect to the wind pressure from the back of the solar cell module, the force of this rising is suppressed by the pressing of the first bent portion 1 of the fixing device K, and A pull-out stress is not applied to the fastening portion of the frame member of the module 20a. Further, the force for pulling up the first bent portion 1 is dispersed to the fastening portions of the second bent portion 2 and the fourth bent portion 4, so that the stress applied to the fastening portion 9 is reduced as much as possible to reduce the stress of the fastening member 11. The burden is also reduced. Similarly, also in the case of the solar cell module 20b, the third bent portion 3 suppresses the floating of the solar cell module 20b, and does not come off from the vertical member 5 by the fastening portion of the second bent portion 2 and the fourth bent portion 4. .
[0020]
Also, since both the first bent portion 1 and the third bent portion 3 are fastened to the longitudinal member 5 by the second bent portion 2 and the fourth bent portion 4, the second bent portion 2 or the Even if the fastening member 11 for fastening the four bent portions 4 falls off, the solar cell modules 20a and 20b are held without falling off. Furthermore, even when both of the fastening members 11 fall off, the solar cell module 20 is sandwiched between the first bent portion 1 and the fourth bent portion 4, the third bent portion 3 and the second bent portion 2, If one of them rises, the other will be lifted through the fixing device K. If there is no wind pressure for lifting two solar cell modules, the solar cell module will not rise, so that it will not easily fall off and the safety will be improved.
[0021]
In addition, since a gap is formed between the solar cell modules by the fixing device K, the wind is easily released and the wind resistance is increased. In addition, because of good drainage of rain and snow, damage due to freezing is less likely to occur.
[0022]
Further, since the frame member of the solar cell module may be a normal product, the weight is not increased by changing to a thicker one in order to improve the strength, and versatility is not lost. May be the same as the general purpose.
[0023]
However, when a strong wind pressure is applied during a typhoon or the like, if the fixing device K has a sufficient strength, the pulling force concentrates on the fastening member 11, and in the worst case, a problem such as a broken bolt occurs. There is fear. In such a case, a method of improving the strength of the fastening member 11 can be considered. However, if the vertical member 5 is C-shaped or L-shaped, the second bent portion 2 is also moved in the horizontal direction as shown in FIG. It is also possible to use a fixing device K2 that extends and further extends in a direction exactly opposite to the bending direction. Thereby, as shown in FIG. 5, by disposing the second bent portion 2 on the back side of the upper surface of the vertical member 5, as shown in FIG. 6, the force that the solar cell modules 20a and 20b try to float as shown in FIG. The first bending portion 1 and the third bending portion 3 suppress the force, and the force for pulling out the fixing device K2 itself is directly supported by the vertical members 5 by the second bending portion 2, thereby reducing the stress applied to the fastening member 11. be able to. Note that a fastening portion 9 is provided in the second bent portion 2.
[0024]
Thus, when trying to rise against the wind pressure from the back of the solar cell module, the rising force is suppressed by the pressing of the first bent portion of the fixing device, and the force is pulled out at the fastening portion of the frame member of the solar cell module. No stress is applied. Thus, the strength of the frame member of the solar cell module and members similar thereto need not be increased, and an increase in the weight of the solar cell module can be avoided. In addition, since the fastening material for fastening one solar cell module to the vertical member supports the other solar cell module via the fixing device, the solar cell module cannot be dropped even if a part of the fastening member falls off. And the safety is improved. Furthermore, even if the fixing bolt of any one of the solar cell modules falls off, it is possible to prevent the adjacent solar cell module from falling off and to eliminate the deflection near the center of the solar cell module. A fixed structure can be provided.
[0025]
In addition, since the fastening material for fastening one solar cell module to the vertical member supports the other solar cell module via the fixing device, the solar cell module cannot be dropped even if a part of the fastening member falls off. And the safety is improved. Further, a gap is formed between the solar cell modules by the fixing device, so that the wind easily escapes and the wind resistance is increased. In addition, because of good drainage of rain and snow, damage due to freezing is less likely to occur.
[0026]
Also, since the frame member of the solar cell module may be a normal product, the weight is increased by changing to a thicker one in order to improve the strength, and the versatility is not lost, and the transportation means is also reduced. It can be the same as general purpose.
[0027]
In addition, the force by which the solar cell module tends to float is suppressed by the first bent portion and the third bent portion, and the force by which the fixing device itself is pulled out is directly supported by the second bent portion by the vertical member, so that the fastening member is provided. It is possible to reduce the stress applied to the load.
[0028]
Furthermore, by fixing the fixing device provided on the contact surface of the solar cell module with the frame member to the long side frame of the solar cell module instead of the installation base, the fixing bolt of one of the solar cell modules may fall off. In addition, it is possible to provide an excellent fixing device capable of preventing falling off by supporting the adjacent solar cell module and eliminating bending near the center of the solar cell module.
[0029]
Next, a modified example of the fixing device according to the present invention will be described. As shown in FIG. 7 (a), a fixing device K3 provided with a fastening portion 9 between an upper bent portion and a lower bent portion is connected to a solar cell module via a fastening member 11 such as a bolt instead of a mounting frame. You may make it attach to 20 long side frames.
[0030]
In this case, even if the fixing device K3 is simply attached to the solar cell module 20 as shown in FIG. effective. When the long side of the solar cell module is relatively long, a phenomenon occurs in which the vicinity of the center is bent by the weight of the solar cell module. Therefore, in addition to the fixing device K fastened to the vertical member 5, the fixing device K3 is disposed in the middle. By arranging, adjacent solar cell modules are supported by each other, and the deflection near the center is eliminated. In addition, since the solar cell module located at the end does not have a supporting solar cell module, the frame member is reinforced by the reinforcing plate 12 or the like.
[0031]
In this way, no special processing is required for the solar cell module, and the resistance to wind pressure from the back of the solar cell module is improved, and the solar cell module is not easily detached even if the fastening member comes off due to an accident. Mechanism.
[0032]
In the present embodiment, a solar cell module has been mainly described as an example of a solar utilization device. However, a similar operation and effect can be expected in a flat solar heat collector or the like, which deviates from the gist of the present invention. The present invention can be appropriately changed and implemented within a range not to be performed.
[0033]
