Description

本発明は、建造物等の固定側部材に張設される膜体の表面に取付具により太陽電池を取り付けるようにした太陽電池取付構造、およびその形成方法に関するものである。   The present invention relates to a solar cell mounting structure in which a solar cell is mounted on a surface of a film body stretched on a stationary member such as a building by a mounting tool, and a method for forming the solar cell mounting structure.

上記太陽電池取付構造には、従来、下記特許文献1や特許文献2の特に図2に示されるものがある。これら各公報のものによれば、太陽電池取付構造は、固定側部材に張設される膜体と、この膜体の表面に沿って設けられる可撓性板形状の太陽電池と、この太陽電池を上記膜体に取り付ける取付具とを備えている。   Conventional solar cell mounting structures include those shown in FIG. 2 of Patent Document 1 and Patent Document 2 below. According to these publications, the solar cell mounting structure includes a film body stretched on the fixed-side member, a flexible plate-shaped solar cell provided along the surface of the film body, and the solar cell. Is attached to the film body.

そして、上記太陽電池に達した太陽光は、その光エネルギーが電気エネルギーに変換され、その後、バッテリに充電されたり、その他の電気機器に供給されたりして、自然光が有効利用されるようになっている。   The sunlight that has reached the solar cell is converted into electrical energy, and then the battery is charged or supplied to other electrical devices, so that natural light is effectively utilized. ing.

特開2011−60794号公報JP 2011-60794 A 特許第4325107号公報Japanese Patent No. 4325107

ところで、上記太陽電池取付構造における膜体の面方向に向かって引張力を与えたときの膜体の伸び量(mm/N)は、通常、上記太陽電池のそれよりも大きいものである。   By the way, the extension amount (mm / N) of the film body when a tensile force is applied in the surface direction of the film body in the solar cell mounting structure is usually larger than that of the solar cell.

このため、上記膜体に対し、例えば、自然現象として風や積雪などから大きい外部荷重が与えられたときには、上記膜体はその面方向に向かって上記太陽電池よりも大きく伸長変形しようとする。すると、この場合には、上記取付具を介し膜体から太陽電池に対し上記膜体の伸長変形に基づく負荷が与えられる。また、この際、この負荷に基づく反力が上記取付具を介し太陽電池から膜体に与えられる。   For this reason, for example, when a large external load is applied to the film body from, for example, wind or snow as a natural phenomenon, the film body tends to expand and deform larger than the solar cell in the surface direction. Then, in this case, a load based on the extension deformation of the film body is applied from the film body to the solar cell through the fixture. At this time, a reaction force based on the load is applied from the solar cell to the film body via the fixture.

つまり、上記従来の技術によれば、膜体とこの膜体に接合された太陽電池とが互いに無用の負荷を与え合うため、これら負荷により、特に上記膜体よりも伸び率が小さい太陽電池がわが早期に損傷しがちとなって、その太陽電池素子に断線が生じたりエネルギー変換性能が低下したりし、この結果、上記した無用の負荷により、上記膜体や太陽電池に寿命上の問題点を生じるおそれがある。   In other words, according to the above-described conventional technology, the film body and the solar cell joined to the film body give unnecessary loads to each other. Therefore, the solar cell having an elongation rate smaller than that of the film body is caused by these loads. It tends to be damaged early on, and the solar cell element is disconnected or the energy conversion performance is lowered. As a result, the above-mentioned useless load causes a problem in the life of the film body or solar cell. May occur.

本発明は、上記のような事情に注目してなされたもので、本発明の目的は、建造物等固定側部材に張設された膜体の表面に取付具により太陽電池を取り付けた場合に、自然現象などに基づき上記膜体と太陽電池とが互いに無用な負荷を与え合うことを防止して、特に太陽電池における太陽電池素子の断線防止やエネルギー変換性能の低下防止を図ることにより、上記膜体や太陽電池の寿命を向上させることである。   The present invention has been made paying attention to the above situation, and the object of the present invention is when a solar cell is attached to the surface of a film body stretched on a stationary member such as a building with a fixture. By preventing the film body and the solar cell from applying unnecessary loads to each other based on natural phenomena, in particular, by preventing disconnection of the solar cell element in the solar cell and preventing reduction in energy conversion performance, It is to improve the lifetime of the film body and the solar cell.

本発明による効果は、次の如くである。   The effects of the present invention are as follows.

請求項1の発明は、固定側部材に張設される膜体と、この膜体の表面に沿って設けられる可撓性板形状の太陽電池と、この太陽電池を上記膜体に取り付ける取付具とを備え、上記膜体に、その面方向に向かって引張力を与えたときの伸び率の値と、上記太陽電池のそれとが互いに相違する太陽電池取付構造において、
上記取付具が、上記膜体の表面に沿って設けられ、その面方向の一端部がわが上記膜体に接合され、他端部がわが上記太陽電池に接合される弾性取付板を有している。
The invention according to claim 1 is a film body stretched on the fixed member, a flexible plate-shaped solar cell provided along the surface of the film body, and a fixture for attaching the solar cell to the film body In the solar cell mounting structure in which the value of elongation when the film body is given a tensile force toward the surface direction is different from that of the solar cell,
The fixture is provided along the surface of the film body, and has an elastic mounting plate whose one end in the surface direction is joined to the film body and the other end is joined to the solar cell. Yes.

このため、上記膜体に対し風や積雪などから大きい外部荷重が与えられて、上記膜体がその面方向に向かって上記太陽電池よりも大きく伸長変形しようとするときには、上記膜体の伸長変形に応じて上記弾性取付板が弾性変形する。   For this reason, when a large external load is applied to the film body from wind, snow, etc., the film body tends to expand and deform more greatly than the solar cell in the surface direction. Accordingly, the elastic mounting plate is elastically deformed.

よって、上記膜体の伸長変形によりこの膜体から太陽電池に負荷が与えられることは上記弾性取付板の弾性変形により防止され、かつ、上記膜体の伸長変形による負荷に基づく反力が上記弾性取付板を介し太陽電池から膜体に与えられることも未然に防止される。つまり、上記発明によれば、膜体とこの膜体に接合された太陽電池とが互いに無用の負荷を与え合うことは、上記弾性取付板の弾性変形により防止される。この結果、特に太陽電池における太陽電池素子に無用な負荷が与えられることによる太陽電池素子の断線やエネルギー変換性能の低下が防止されて、上記膜体と太陽電池との寿命の向上が達成される。   Therefore, it is prevented that a load is applied from the film body to the solar cell due to the expansion deformation of the film body, and a reaction force based on the load due to the expansion deformation of the film body is prevented by the elastic deformation of the film body. It is also possible to prevent the solar cell from being applied to the film body via the mounting plate. That is, according to the invention, the film body and the solar cell bonded to the film body are prevented from applying unnecessary loads to each other by the elastic deformation of the elastic mounting plate. As a result, disconnection of the solar cell element and reduction in energy conversion performance due to an unnecessary load being applied to the solar cell element particularly in the solar cell are prevented, and improvement in the life of the film body and the solar cell is achieved. .

また、上記弾性取付板は板形状であるため、これを紐形状などにすることに比べ、この弾性取付板がわと膜体および太陽電池との互いの接合面積を大きくできてその接合強度を大きくでき、上記膜体への太陽電池の取り付けが強固になされる。よって、前記したように外部荷重に基づき膜体が伸長変形してこの膜体から太陽電池に負荷が与えられる場合に、上記膜体から上記太陽電池が剥離するなどの不都合の発生は防止される。この結果、上記膜体と太陽電池との寿命の向上が達成される。   In addition, since the elastic mounting plate has a plate shape, the elastic mounting plate can increase the bonding area between the film, the film body, and the solar cell compared with the case where the elastic mounting plate is formed into a string shape. The solar cell can be firmly attached to the film body. Therefore, as described above, when the film body is elongated and deformed based on the external load and a load is applied from the film body to the solar cell, occurrence of inconvenience such as separation of the solar cell from the film body is prevented. . As a result, the lifetime of the film body and the solar cell is improved.

請求項2の発明は、上記取付具が、上記膜体と弾性取付板の一端部との間に介設される取付膜材を有し、この取付膜材の面方向の一端部と上記膜体とを互いに接合し、上記取付膜材の他端部の外面を改質面としてこの外面と上記弾性取付板の一端部とを互いに接着している。   The invention of claim 2 is characterized in that the fixture has an attachment film material interposed between the membrane body and one end portion of the elastic attachment plate, and one end portion of the attachment film material in the surface direction and the membrane The body is bonded to each other, and the outer surface of the other end portion of the mounting film member is used as a modified surface, and the outer surface and one end portion of the elastic mounting plate are bonded to each other.

ここで、上記取付膜材は、これを所望の大きさや所望の形状に加工したり、切断したりすることが容易にできるものであるため、当該太陽電池取付構造に、上記のような取付膜材を用いたことにより、膜体への太陽電池の取り付け作業が容易にできると共に、太陽電池の取り替え作業も容易にできる。   Here, since the attachment film material can be easily processed into a desired size or a desired shape or cut, the attachment film as described above is included in the solar cell attachment structure. By using the material, the solar cell can be easily attached to the film body, and the solar cell can be easily replaced.

また、上記弾性取付板は、通常、ゴム材製であるため、そのままの状態で、この弾性取付板と上記取付膜材とを溶着することは、材質上、困難である。そこで、この溶着に代えて、縫着することが考えられるが、この場合には糸を通す穿孔のために雨水が浸入し易くなったり強度低下が生じ易くなったりするおそれがある。このため、上記弾性取付板と上記取付膜材とを溶着や縫着により互いに接合することは事実上困難である。   Further, since the elastic mounting plate is usually made of a rubber material, it is difficult in terms of material to weld the elastic mounting plate and the mounting film material as they are. Therefore, instead of this welding, it is conceivable to sew. However, in this case, there is a risk that rainwater may easily enter due to perforation through which the thread passes, or that strength may be easily reduced. For this reason, it is practically difficult to join the elastic mounting plate and the mounting film material to each other by welding or sewing.

そこで、前記したように、取付膜材の他端部の外面を改質面としてこの外面と上記弾性取付板の一端部とを互いに接着したのであり、これにより、上記弾性取付板の一端部と取付膜材の他端部とを強固に接着することができ、上記膜体への太陽電池の取り付けが強固になされる。よって、前記したように外部荷重に基づき膜体が伸長変形してこの膜体から太陽電池に負荷が与えられる場合に、上記膜体から上記太陽電池が剥離するなどの不都合の発生は防止される。この結果、これら膜体と太陽電池との寿命の向上が、より確実に達成される。   Therefore, as described above, the outer surface of the other end portion of the mounting film material is used as a modified surface, and this outer surface and one end portion of the elastic mounting plate are bonded to each other. The other end of the attachment film material can be firmly adhered, and the solar cell can be firmly attached to the film body. Therefore, as described above, when the film body is elongated and deformed based on the external load and a load is applied from the film body to the solar cell, occurrence of inconvenience such as separation of the solar cell from the film body is prevented. . As a result, the improvement of the lifetime of these film bodies and solar cells is achieved more reliably.

請求項3の発明は、上記取付具が、上記太陽電池と弾性取付板の他端部との間に介設される取付膜材を有し、この取付膜材の面方向の一端部と上記太陽電池とを互いに接合し、上記取付膜材の他端部の外面を改質面としてこの外面と上記弾性取付板の他端部とを互いに接着している。   According to a third aspect of the present invention, the fixture includes a mounting film material interposed between the solar cell and the other end portion of the elastic mounting plate, and one end portion in the surface direction of the mounting film material and the above The solar cells are bonded to each other, and the outer surface of the other end portion of the mounting film material is used as a modified surface, and the outer surface and the other end portion of the elastic mounting plate are bonded to each other.

ここで、上記取付膜材は、これを所望の大きさや所望の形状に加工したり、切断したりすることが容易にできるものであるため、当該太陽電池取付構造に、上記のような取付膜材を用いたことにより、膜体への太陽電池の取り付け作業が容易にできると共に、太陽電池の取り替え作業も容易にできる。   Here, since the attachment film material can be easily processed into a desired size or a desired shape or cut, the attachment film as described above is included in the solar cell attachment structure. By using the material, the solar cell can be easily attached to the film body, and the solar cell can be easily replaced.

また、上記弾性取付板は、通常、ゴム材製であるため、そのままの状態で、この弾性取付板と上記取付膜材とを溶着することは、材質上、困難である。そこで、この溶着に代えて、縫着することが考えられるが、この場合には糸を通す穿孔のために雨水が浸入し易くなったり強度低下が生じ易くなったりするおそれがある。このため、上記弾性取付板と上記取付膜材とを溶着や縫着により互いに接合することは事実上困難である。   Further, since the elastic mounting plate is usually made of a rubber material, it is difficult in terms of material to weld the elastic mounting plate and the mounting film material as they are. Therefore, instead of this welding, it is conceivable to sew. However, in this case, there is a risk that rainwater may easily enter due to perforation through which the thread passes, or that strength may be easily reduced. For this reason, it is practically difficult to join the elastic mounting plate and the mounting film material to each other by welding or sewing.

そこで、前記したように、取付膜材の他端部の外面を改質面としてこの外面と上記弾性取付板の他端部とを互いに接着したのであり、これにより、上記弾性取付板の他端部と他の取付膜材の他端部とを強固に接着することができ、上記膜体への太陽電池の取り付けが強固になされる。よって、前記したように外部荷重に基づき膜体が伸長変形してこの膜体から太陽電池に負荷が与えられる場合に、上記膜体から上記太陽電池が剥離するなどの不都合の発生は防止される。この結果、これら膜体と太陽電池との寿命の向上が、より確実に達成される。   Therefore, as described above, the outer surface of the other end portion of the mounting film material is used as a modified surface, and the outer surface and the other end portion of the elastic mounting plate are bonded to each other. And the other end portion of the other attachment film material can be firmly bonded, and the solar cell can be firmly attached to the film body. Therefore, as described above, when the film body is elongated and deformed based on the external load and a load is applied from the film body to the solar cell, occurrence of inconvenience such as separation of the solar cell from the film body is prevented. . As a result, the improvement of the lifetime of these film bodies and solar cells is achieved more reliably.

請求項4の発明は、上記取付具が、上記膜体と弾性取付板の一端部との間に介設される取付膜材を有し、この取付膜材の面方向の一端部と上記膜体とを互いに接合し、上記取付膜材の他端部と上記弾性取付板の一端部とを互いに係止する係止部を設けている。   According to a fourth aspect of the present invention, the fixture includes a mounting film material interposed between the film body and one end portion of the elastic mounting plate, and one end portion in the surface direction of the mounting film material and the film The body is joined to each other, and a locking portion is provided to lock the other end of the mounting film member and one end of the elastic mounting plate.

このため、上記取付具による膜体への太陽電池の取り付け作業において、例えば、予め、膜体に上記取付膜材の一端部を接合しておき、その後、上記固定側部材への膜体の張設の前、後のいずれかにおいて、上記取付膜材の他端部に、太陽電池を取り付けた弾性取付板の一端部を上記係止部により係止させることができる。よって、上記膜体への太陽電池の取り付け作業の自由度が向上すると共に、上記係止部により上記膜体への太陽電池の取り付け作業が極めて容易にできる。   For this reason, in the operation of attaching the solar cell to the film body using the fixture, for example, one end of the attachment film material is bonded to the film body in advance, and then the film body is stretched to the fixed member. Either before or after the installation, one end of the elastic mounting plate to which the solar cell is attached can be locked to the other end of the mounting film material by the locking portion. Therefore, the degree of freedom of the operation of attaching the solar cell to the film body is improved, and the operation of attaching the solar cell to the film body can be extremely easily performed by the locking portion.

請求項5の発明は、上記取付具が、上記太陽電池と弾性取付板の他端部との間に介設される取付膜材を有し、この取付膜材の面方向の一端部と上記太陽電池とを互いに接合し、上記取付膜材の他端部と上記弾性取付板の他端部とを互いに係止する係止部を設けている。   According to a fifth aspect of the present invention, the fixture includes a mounting film material interposed between the solar cell and the other end portion of the elastic mounting plate, and one end portion in the surface direction of the mounting film material and the above The solar cell is joined to each other, and a locking portion is provided to lock the other end portion of the mounting film material and the other end portion of the elastic mounting plate.

このため、上記取付具による膜体への太陽電池の取り付け作業において、例えば、予め、膜体に上記弾性取付板の一端部がわを接合しておき、その後、上記固定側部材への膜体の張設の前、後のいずれかにおいて、上記弾性取付板の他端部に、太陽電池を取り付けた上記取付膜材の他端部を上記係止部により係止させることができる。よって、上記膜体への太陽電池の取り付け作業の自由度が向上すると共に、上記係止部により上記膜体への太陽電池の取り付け作業が極めて容易にできる。   For this reason, in the operation of attaching the solar cell to the film body by the mounting tool, for example, one end of the elastic mounting plate is joined to the film body in advance, and then the film body to the fixed-side member. Either before or after tensioning, the other end portion of the attachment film material to which the solar cell is attached can be engaged with the other end portion of the elastic attachment plate by the engagement portion. Therefore, the degree of freedom of the operation of attaching the solar cell to the film body is improved, and the operation of attaching the solar cell to the film body can be extremely easily performed by the locking portion.

請求項6の発明は、上記係止部の引張弾性率(MPa)を、上記弾性取付板の上記面方向における中途部の引張弾性率(MPa)の値よりも大きくしている。   According to a sixth aspect of the present invention, the tensile elastic modulus (MPa) of the locking portion is made larger than the tensile elastic modulus (MPa) of the midway portion in the surface direction of the elastic mounting plate.

このため、上記弾性取付板には必要な弾性性能が維持される一方、上記した係止部による弾性取付板への取付膜材の他端部の係止が強固になされることから、上記係止部による膜体への太陽電池の取付強度が十分に確保される。よって、前記したように、係止部により膜体への太陽電池の取り付け作業が容易にできるものでありながら、前記したように外部荷重に基づき膜体が伸長変形してこの膜体から太陽電池に負荷が与えられる場合に、上記膜体から上記太陽電池が剥離するなどの不都合の発生は防止される。この結果、これら膜体と太陽電池との寿命の向上が達成される。   For this reason, while the necessary elastic performance is maintained in the elastic mounting plate, the engagement of the other end portion of the mounting film material to the elastic mounting plate by the locking portion described above is firmly performed. The mounting strength of the solar cell to the film body by the stopper is sufficiently secured. Therefore, as described above, the solar cell can be easily attached to the film body by the engaging portion, but the film body is elongated and deformed based on the external load as described above, and the solar cell is removed from the film body. When a load is applied to the film body, inconveniences such as peeling of the solar cell from the film body are prevented. As a result, the improvement of the lifetime of these film bodies and solar cells is achieved.

請求項7の発明は、上記弾性取付板の引張弾性率(MPa)の値を10〜100としている。   In the invention of claim 7, the value of the tensile elastic modulus (MPa) of the elastic mounting plate is 10 to 100.

ここで、上記弾性取付板の引張弾性率の値を10未満にすると、上記弾性取付板による膜体への太陽電池の取付強度が不十分になりがちである。一方、上記引張弾性率の値が100を越えると、前記した膜体の伸長変形による負荷が太陽電池に与えられようとするときの弾性取付板の弾性変形が不十分になりがちである。   Here, if the value of the tensile elastic modulus of the elastic mounting plate is less than 10, the mounting strength of the solar cell to the film body by the elastic mounting plate tends to be insufficient. On the other hand, when the value of the tensile elastic modulus exceeds 100, the elastic deformation of the elastic mounting plate tends to be insufficient when a load due to the extension deformation of the film body is applied to the solar cell.

そこで、上記したように弾性取付板の引張弾性率の値を10〜100としたのであり、このようにすれば、上記弾性取付板による膜体への太陽電池の取付強度が十分に確保できる。また、上記取付具を一般的な樹脂材にすることに比べ、上記弾性取付板によれば、十分な弾性変形量が得られて、上記膜体と太陽電池とが互いに無用の負荷を与え合うことは上記弾性取付板の弾性変形によって、より確実に防止される。よって、特に太陽電池における太陽電池素子に無用な負荷が与えられることによる太陽電池素子の断線やエネルギー変換性能の低下が防止されて、上記膜体と太陽電池との寿命の向上が、より確実に達成される。   Therefore, as described above, the value of the tensile modulus of elasticity of the elastic mounting plate is set to 10 to 100. By doing so, the mounting strength of the solar cell to the film body by the elastic mounting plate can be sufficiently secured. Further, compared to the case where the fixture is made of a general resin material, the elastic mounting plate can provide a sufficient amount of elastic deformation, and the film body and the solar cell give unnecessary loads to each other. This is more reliably prevented by the elastic deformation of the elastic mounting plate. Therefore, the disconnection of the solar cell element and the deterioration of the energy conversion performance due to the unnecessary load being applied to the solar cell element particularly in the solar cell are prevented, and the improvement in the lifetime of the film body and the solar cell is more reliably performed. Achieved.

請求項8の発明は、請求項1に記載の太陽電池取付構造の形成方法であって、
まず、固定側部材に張設される膜体に初期引張力を付与し、その後、この膜体に対し上記取付具により太陽電池を取り付けている。
Invention of Claim 8 is a formation method of the solar cell attachment structure of Claim 1, Comprising:
First, an initial tensile force is applied to the film body stretched on the fixed side member, and then the solar cell is attached to the film body with the above-described fixture.

このため、膜体に予め初期引張力が付与されて初期変形させられることから、この膜体に、その後、何らかの外部荷重が与えられたときには、上記膜体が初期変形させられている分、上記外部荷重により伸長変形する膜体から上記取付具を介し太陽電池に与えられる負荷は小さく抑制されて、膜体と太陽電池とが互いに無用の負荷を与え合うことは、更に確実に防止される。この結果、特に太陽電池における太陽電池素子に無用な負荷が与えられることによる太陽電池素子の断線やエネルギー変換性能の低下が防止されて、上記膜体と太陽電池との寿命の向上が、更に確実に達成される。   For this reason, since an initial tensile force is preliminarily applied to the film body and the film body is initially deformed, when the film body is subsequently subjected to some external load, the film body is initially deformed. The load applied to the solar cell from the film body that is stretched and deformed by an external load through the fixture is suppressed to be small, and the film body and the solar cell are more reliably prevented from applying unnecessary loads to each other. As a result, disconnection of the solar cell element and reduction in energy conversion performance due to an unnecessary load being applied to the solar cell element in the solar cell are prevented, and the lifetime of the film body and the solar cell is further improved. To be achieved.

本発明の太陽電池取付構造に関し、建造物等固定側部材に張設された膜体の表面に取付具により太陽電池を取り付けた場合に、自然現象などに基づき上記膜体と太陽電池とが互いに無用な負荷を与え合うことを防止して、特に太陽電池における太陽電池素子の断線防止やエネルギー変換性能の低下防止を図ることにより、上記膜体や太陽電池の寿命を向上させるようにする、という目的を実現するため、本発明を実施するための形態は、次の如くである。   In the solar cell mounting structure of the present invention, when a solar cell is attached to the surface of a film body stretched on a stationary member such as a building with a fixture, the film body and the solar cell are mutually connected based on a natural phenomenon or the like. It is said that the life of the above-mentioned film body and solar cell is improved by preventing the application of unnecessary loads, particularly by preventing the disconnection of the solar cell element in the solar cell and preventing the deterioration of the energy conversion performance. In order to achieve the object, the mode for carrying out the present invention is as follows.

即ち、太陽電池取付構造は、固定側部材に張設される膜体と、この膜体の表面に沿って設けられる可撓性板形状の太陽電池と、この太陽電池を上記膜体に取り付ける取付具とを備える。上記膜体に、その面方向に向かって引張力を与えたときの伸び率の値と、上記太陽電池のそれとは互いに相違する。上記取付具は弾性取付板を有し、この弾性取付板は、上記膜体の表面に沿って設けられ、その面方向の一端部がわが上記膜体に接合され、他端部がわが上記太陽電池に接合される。   That is, the solar cell mounting structure includes a film body stretched on the fixed member, a flexible plate-shaped solar cell provided along the surface of the film body, and an attachment for mounting the solar cell on the film body. Equipment. The value of the elongation rate when a tensile force is applied to the film body in the surface direction is different from that of the solar cell. The fixture has an elastic mounting plate, and the elastic mounting plate is provided along the surface of the film body, one end of the surface direction is joined to the film body, and the other end is the sun. Joined to the battery.

本発明をより詳細に説明するために、その実施例1を添付の図1(a)と図2とに従って説明する。   In order to describe the present invention in more detail, the first embodiment will be described with reference to FIG. 1 (a) and FIG.

図1(a)と図2とにおいて、符号1は膜状太陽光発電装置である。この太陽光発電装置1は、建造物などの固定側部材2に張設される膜体4と、この膜体4の表面(上面)に沿って延びると共にこの表面上に配置される可撓性板形状の複数の太陽電池5と、これら各太陽電池5をそれぞれ上記膜体4に取り付ける取付具6とを備えている。   In FIG. 1 (a) and FIG. 2, the code | symbol 1 is a film-form solar power generation device. This solar power generation device 1 includes a film body 4 stretched on a stationary member 2 such as a building, and a flexibility that extends along the surface (upper surface) of the film body 4 and is disposed on the surface. A plurality of plate-shaped solar cells 5 and a fixture 6 for attaching the solar cells 5 to the film body 4 are provided.

上記膜体4は、その表面が太陽光に向かうよう水平もしくは水平面に対し傾斜した方向に延びている。上記膜体4は、その面方向の少なくとも一方向Aに向かって所定値の初期引張力T(N/m)が付与されている。この膜体4は、ケナフ繊維等の天然繊維、ポリエステル繊維等の合成繊維、もしくはガラス繊維等の無機繊維等により形成される織物である基材と、この基材の表裏の各外面に被覆(コーティング)されるポリ塩化ビニル(PVC)やフッ素樹脂など熱可塑性樹脂材製の外面材(コーティング材)とを備えている。なお、上記膜体4の外面材は、少なくとも熱により溶着する部分の外面がポリ塩化ビニルやフッ素樹脂等の熱可塑性樹脂であればよく、その他の部分の外面には、汚れ防止のための光触媒層等を設けていてもよいし、もしくは、上記熱可塑性樹脂に光触媒粒子を含有させることにより光触媒層としてもよい。   The film body 4 extends in a direction inclined with respect to the horizontal or horizontal plane so that the surface thereof faces sunlight. The film body 4 is given an initial tensile force T (N / m) having a predetermined value in at least one direction A in the plane direction. This film body 4 is coated with a base material that is a woven fabric formed of natural fibers such as kenaf fibers, synthetic fibers such as polyester fibers, or inorganic fibers such as glass fibers, and outer surfaces on the front and back of the base material ( And an outer surface material (coating material) made of a thermoplastic resin material such as polyvinyl chloride (PVC) or fluororesin. The outer surface material of the film body 4 may be a thermoplastic resin such as polyvinyl chloride or fluororesin, at least the outer surface of the portion to be welded by heat, and the outer surface of the other portion has a photocatalyst for preventing contamination. A layer or the like may be provided, or a photocatalyst layer may be formed by adding photocatalyst particles to the thermoplastic resin.

上記各太陽電池5はそれぞれ上記一方向Aに直交する直交方向Bに長く延びる長方形をなし、互いに同形同大とされている。これら各太陽電池5は、上記膜体4の面方向での上記一方向Aと直交方向Bとに碁盤目状となるよう上記膜体4の表面上に配置されている。上記各太陽電池5は、その表面(上面)で太陽光を受光してその光エネルギーを電気エネルギーに変換する太陽電池素子9と、この太陽電池素子9を全体的に覆ってこの太陽電池素子9の外面に固着される表面材10と、上記太陽電池素子9の電気エネルギーを集めて外部に出力する端子ボックス11とを備えている。上記表面材10は、フッ素樹脂など熱可塑性樹脂材製の透明なフィルムとされ、例えば、ポリエチレンテレフタレート(PET)や、テトラフルオロエチレン-エチレン共重合体(ETFE)等により形成されている。   Each of the solar cells 5 has a rectangular shape extending in the orthogonal direction B orthogonal to the one direction A, and has the same shape and size. Each of these solar cells 5 is arranged on the surface of the film body 4 so as to have a grid pattern in the one direction A and the orthogonal direction B in the plane direction of the film body 4. Each of the solar cells 5 receives solar light on its surface (upper surface) and converts the light energy into electric energy, and the solar cell element 9 entirely covers the solar cell element 9. And a terminal box 11 that collects the electric energy of the solar cell element 9 and outputs it to the outside. The surface material 10 is a transparent film made of a thermoplastic resin material such as a fluororesin, and is formed of, for example, polyethylene terephthalate (PET), tetrafluoroethylene-ethylene copolymer (ETFE), or the like.

ここで、上記膜体4に、その面方向の一方向Aおよび直交方向Bに向かってそれぞれ引張力Tを与えたときの伸び量(mm/N)は、上記太陽電池5のそれよりもかなり大きい値であり、両者の値は互いに相違している。   Here, the amount of elongation (mm / N) when the film body 4 is given a tensile force T in one direction A and in the orthogonal direction B in the plane direction is considerably larger than that of the solar cell 5. It is a large value, and both values are different from each other.

上記取付具6は、その全体がゴム材製であって可撓性も有する弾性取付板14を有している。この弾性取付板14は、上記膜体4の外面に沿って、かつ、太陽電池5の外端縁部に沿って設けられ、太陽光発電装置1の平面視(図2)で、長方形の枠形状をなしている。ここで、樹脂材とゴム材とは、これらを互いに溶着させたり縫着させたりすることは事実上困難である。そこで、上記弾性取付板14の面方向の一端部14aである外端縁部は上記膜体4の外面に樹脂系の接着剤15により接着されて接合され、他端部14bである内端縁部が上記太陽電池5の外端縁部の表面(上面)の表面材10に接着剤15により接着されて接合されている。   The fixture 6 has an elastic mounting plate 14 that is entirely made of rubber and has flexibility. The elastic mounting plate 14 is provided along the outer surface of the film body 4 and along the outer edge of the solar cell 5, and is a rectangular frame in a plan view of the solar power generation device 1 (FIG. 2). It has a shape. Here, it is practically difficult for the resin material and the rubber material to be welded or sewn together. Therefore, the outer end edge portion which is one end portion 14a in the surface direction of the elastic mounting plate 14 is bonded and joined to the outer surface of the film body 4 with a resin adhesive 15, and the inner end edge which is the other end portion 14b. The portion is bonded and bonded to the surface material 10 on the surface (upper surface) of the outer edge portion of the solar cell 5 by an adhesive 15.

なお、上記取付具6は、図示のように長方形の枠形状に設けることが好ましいが、長方形の枠形状だけでなく、必要に応じて少なくとも上記太陽電池5の一辺に設けられていれば良く、また、上記一辺の全てに設けていてもよいし、各辺のうち必要な箇所に設けてもよい。   The attachment 6 is preferably provided in a rectangular frame shape as shown in the figure, but not only in the rectangular frame shape, it may be provided at least on one side of the solar cell 5 as necessary. Moreover, you may provide in all the said one sides, and you may provide in a required location among each side.

また、上記弾性取付板14としては、上記ゴム材製の他に、スパンデックス等の弾性糸を使用した伸縮性を有する布の基布表面に、ポリウレタン樹脂等からなる高伸度の熱可塑性樹脂を被覆し、破断伸度を50〜500%としたものであってもよい。このような弾性取付板にすれば、接着だけでなく溶着することも可能となる。   In addition to the rubber material, the elastic mounting plate 14 is made of a high-stretch thermoplastic resin made of polyurethane resin or the like on the surface of a stretchable cloth using elastic yarn such as spandex. It may be coated and the elongation at break may be 50 to 500%. If such an elastic mounting plate is used, not only adhesion but also welding can be performed.

上記構成の太陽光発電装置1における太陽電池取付構造によれば、上記膜体4に対し風や積雪などから大きい外部荷重が与えられて、上記膜体4がその面方向に向かって上記太陽電池5よりも大きく伸長変形しようとするときには、上記膜体4の伸長変形に応じて上記弾性取付板14が弾性変形する。   According to the solar cell mounting structure in the solar power generation device 1 having the above-described configuration, a large external load is applied to the film body 4 from wind, snow, or the like, and the film body 4 moves toward the surface. When it is going to extend and deform more than 5, the elastic mounting plate 14 is elastically deformed according to the expansion and deformation of the film body 4.

よって、上記膜体4の伸長変形によりこの膜体4から太陽電池5に負荷が与えられることは上記弾性取付板14の弾性変形により防止され、かつ、上記膜体4の伸長変形による負荷に基づく反力が上記弾性取付板14を介し太陽電池5から膜体4に与えられることも未然に防止される。つまり、上記構成によれば、膜体4とこの膜体4に接合された太陽電池5とが互いに無用の負荷を与え合うことは、上記弾性取付板14の弾性変形により防止される。この結果、特に太陽電池における太陽電池素子に無用な負荷が与えられることによる太陽電池素子の断線やエネルギー変換性能の低下が防止されて、上記膜体4と太陽電池5との寿命の向上が達成される。   Therefore, a load applied to the solar cell 5 from the film body 4 due to the extension deformation of the film body 4 is prevented by the elastic deformation of the elastic mounting plate 14 and is based on the load caused by the extension deformation of the film body 4. The reaction force is also prevented from being applied from the solar cell 5 to the film body 4 through the elastic mounting plate 14. That is, according to the above configuration, the film body 4 and the solar cell 5 bonded to the film body 4 are prevented from applying unnecessary loads to each other by the elastic deformation of the elastic mounting plate 14. As a result, disconnection of the solar cell element and reduction in energy conversion performance due to an unnecessary load being applied to the solar cell element particularly in the solar cell are prevented, and an improvement in the lifetime of the film body 4 and the solar cell 5 is achieved. Is done.

また、上記弾性取付板14はシート状等の板形状であるため、これを紐形状などにすることに比べ、この弾性取付板14がわと膜体4および太陽電池5との互いの接合面積を大きくできてその接合強度を大きくでき、上記膜体4への太陽電池5の取り付けが強固になされる。よって、前記したように外部荷重に基づき膜体4が伸長変形してこの膜体4から太陽電池5に負荷が与えられる場合に、上記膜体4から上記太陽電池5が剥離するなどの不都合の発生は防止される。この結果、上記膜体4と太陽電池5との寿命の向上が達成される。   In addition, since the elastic mounting plate 14 has a plate shape such as a sheet shape, the elastic mounting plate 14 has a bonding area between the film body 4 and the solar cell 5 compared to a string shape. The bonding strength can be increased, and the solar cell 5 can be firmly attached to the film body 4. Therefore, as described above, when the film body 4 expands and deforms based on an external load and a load is applied from the film body 4 to the solar cell 5, there is an inconvenience such as peeling of the solar cell 5 from the film body 4. Occurrence is prevented. As a result, the lifetime of the film body 4 and the solar cell 5 is improved.

上記弾性取付板14の引張弾性率E(MPa)の値は10〜100とされている。   The value of the tensile elastic modulus E (MPa) of the elastic mounting plate 14 is 10 to 100.

ここで、上記弾性取付板14の引張弾性率Eの値を10未満にすると、上記弾性取付板14による膜体4への太陽電池5の取付強度が不十分になりがちである。一方、上記引張弾性率Eの値が100を越えると、前記した膜体4の伸長変形による負荷が太陽電池5に与えられようとするときの弾性取付板14の弾性変形が不十分になりがちである。   Here, if the value of the tensile elastic modulus E of the elastic mounting plate 14 is less than 10, the mounting strength of the solar cell 5 to the film body 4 by the elastic mounting plate 14 tends to be insufficient. On the other hand, when the value of the tensile elastic modulus E exceeds 100, the elastic deformation of the elastic mounting plate 14 tends to be insufficient when the load due to the extension deformation of the film body 4 is applied to the solar cell 5. It is.

そこで、上記したように弾性取付板14の引張弾性率Eの値を10〜100としたのであり、このようにすれば、上記弾性取付板14による膜体4への太陽電池5の取付強度が十分に確保できる。また、上記取付具6を一般的な樹脂材(例えば、E=2×10〜5×10(MPa))にすることに比べ、上記弾性取付板14によれば、十分な弾性変形量が得られて、上記膜体4と太陽電池5とが互いに無用の負荷を与え合うことは上記弾性取付板14の弾性変形によって、より確実に防止される。よって、特に太陽電池における太陽電池素子に無用な負荷が与えられることによる太陽電池素子の断線やエネルギー変換性能の低下が防止されて、上記膜体4と太陽電池5との寿命の向上が、より確実に達成される。 Therefore, as described above, the value of the tensile elastic modulus E of the elastic mounting plate 14 is set to 10 to 100. By doing so, the mounting strength of the solar cell 5 to the film body 4 by the elastic mounting plate 14 is increased. Enough can be secured. Moreover, compared with making the said fixture 6 into a general resin material (for example, E = 2 * 10 < 3 > -5 * 10 < 4 > (MPa)), according to the said elastic attachment board 14, sufficient elastic deformation amount Thus, the film body 4 and the solar cell 5 are more reliably prevented from applying unnecessary loads to each other by the elastic deformation of the elastic mounting plate 14. Therefore, the disconnection of the solar cell element and the decrease in the energy conversion performance due to an unnecessary load being applied to the solar cell element particularly in the solar cell are prevented, and the life of the film body 4 and the solar cell 5 is improved. Certainly achieved.

なお、上記弾性取付板14の引張弾性率Eの値は20〜50であることが、より好ましい。   In addition, it is more preferable that the value of the tensile elastic modulus E of the elastic mounting plate 14 is 20-50.

上記太陽光発電装置1のうち、特に、膜体4に太陽電池5を取り付けている太陽電池取付構造の形成方法として、まず、上記固定側部材2に張設される膜体4に初期引張力Tを付与し、その後、この膜体4に対し上記取付具6により太陽電池5を取り付ける、というものである。   Among the solar power generation devices 1, in particular, as a method for forming a solar cell mounting structure in which the solar cell 5 is mounted on the film body 4, first, an initial tensile force is applied to the film body 4 stretched on the fixed side member 2. T is given, and then the solar cell 5 is attached to the film body 4 by the fixture 6.

上記形成方法によれば、膜体4に予め初期引張力Tが付与されて初期変形させられることから、この膜体4に、その後、何らかの外部荷重が与えられたときには、上記膜体4が初期変形させられている分、上記外部荷重により伸長変形する膜体4から上記取付具6を介し太陽電池5に与えられる負荷は小さく抑制されて膜体4と太陽電池5とが互いに無用の負荷を与え合うことは、更に確実に防止される。この結果、特に太陽電池における太陽電池素子に無用な負荷が与えられることによる太陽電池素子の断線やエネルギー変換性能の低下が防止されて、上記膜体4と太陽電池5との寿命の向上が、更に確実に達成される。   According to the above forming method, since the initial tensile force T is applied to the film body 4 in advance and the film body 4 is initially deformed, when the film body 4 is subsequently subjected to some external load, the film body 4 is initialized. The load applied to the solar cell 5 through the fixture 6 from the film body 4 that is extended and deformed by the external load is suppressed to a small extent, and the film body 4 and the solar cell 5 exert unnecessary loads on each other. Giving together is more reliably prevented. As a result, disconnection of the solar cell element due to an unnecessary load being applied to the solar cell element in the solar cell and a decrease in energy conversion performance are prevented, and improvement in the life of the film body 4 and the solar cell 5 is achieved. It is achieved more reliably.

なお、図2中二点鎖線で示すように、上記弾性取付板14は、上記太陽電池5の外端縁部に沿ってほぼ等ピッチで配置される複数枚の取付板片で構成してもよい。また、上記太陽電池5は正方形や円形であってもよい。また、上記膜体4において、弾性取付板14の一端部14aを接着剤15により接着させる部分は、コロナ放電やプラズマ放電などによって、接着し易いような粗面など改質面としてもよい。   2, the elastic mounting plate 14 may be composed of a plurality of mounting plate pieces arranged at substantially equal pitches along the outer edge of the solar cell 5. Good. The solar cell 5 may be square or circular. Further, in the film body 4, a portion where the one end portion 14 a of the elastic mounting plate 14 is bonded by the adhesive 15 may be a modified surface such as a rough surface that is easily bonded by corona discharge or plasma discharge.

以下の図1(b)〜(d)、図3(a)(b)は、実施例2〜6を示している。これら各実施例は、前記実施例1と構成、作用効果において多くの点で共通している。そこで、これら共通するものについては、図面に共通の符号を付してその重複した説明を省略し、異なる点につき主に説明する。また、これら実施例における各部分の構成を、本発明の目的、作用効果に照らして種々組み合せてもよい。   The following FIGS. 1B to 1D and FIGS. 3A and 3B show Examples 2 to 6. Each of these embodiments is common in many respects to the configuration and operational effects of the first embodiment. Therefore, regarding these common items, common reference numerals are attached to the drawings, and redundant description thereof is omitted, and different points are mainly described. In addition, the configuration of each part in these embodiments may be variously combined in light of the object and operational effects of the present invention.

本発明をより詳細に説明するために、その実施例2を添付の図1(b)に従って説明する。   In order to describe the present invention in more detail, the second embodiment will be described with reference to FIG.

図において、上記弾性取付板14の面方向の他端部14bは、上記太陽電池5の外端縁部の裏面(下面)の表面材10に接着剤15により接着されている。   In the figure, the other end portion 14 b in the surface direction of the elastic mounting plate 14 is bonded to the surface material 10 on the back surface (lower surface) of the outer end edge portion of the solar cell 5 with an adhesive 15.

上記構成によれば、弾性取付板14の他端部14bと太陽電池5の外端縁部との接着面積を大きくして、これらの接着強度を大きくしても、上記弾性取付板14の他端部14bが太陽電池5の表面(上面)を覆うことは防止される。よって、上記弾性取付板14による膜体4への太陽電池5の取付強度を大きくできるものでありながら、上記太陽電池5のエネルギー変換性能は良好なままに維持される。   According to the above configuration, even if the adhesion area between the other end portion 14b of the elastic mounting plate 14 and the outer end edge portion of the solar cell 5 is increased to increase the adhesive strength thereof, The end portion 14b is prevented from covering the surface (upper surface) of the solar cell 5. Therefore, while the attachment strength of the solar cell 5 to the film body 4 by the elastic attachment plate 14 can be increased, the energy conversion performance of the solar cell 5 is kept good.

本発明をより詳細に説明するために、その実施例3を添付の図1(c)に従って説明する。   In order to describe the present invention in more detail, the third embodiment will be described with reference to FIG.

図において、上記取付具6は、上記膜体4と弾性取付板14の一端部14aとの間に介設される取付膜材21を有している。この取付膜材21は、太陽光発電装置1の平面視で、上記弾性取付板14と同様に長方形の枠形状とされている。この取付膜材21の面方向(長手方向各部の幅方向)の一端部である外端縁部と上記膜体4とが互いに溶着Wにより接合される。一方、上記取付膜材21の他端部である内端縁部の外面が改質面とされ、この外面と上記弾性取付板14の一端部14aとが互いに接着剤15により接着されている。なお、上記した取付膜材21の一端部と膜体4との接合は、上記溶着Wに代えて接着や縫合によるものであってもよい。また、上記取付膜材21の他端部の外面以外の外面の、全部もしくは一部を前記のような改質面にしてもよい。   In the figure, the fixture 6 has a mounting membrane material 21 interposed between the membrane body 4 and one end portion 14 a of the elastic mounting plate 14. The attachment film material 21 has a rectangular frame shape as in the elastic attachment plate 14 in a plan view of the photovoltaic power generator 1. The outer edge portion, which is one end portion in the surface direction of the attachment film material 21 (the width direction of each part in the longitudinal direction), and the film body 4 are joined to each other by welding W. On the other hand, the outer surface of the inner edge that is the other end of the attachment film material 21 is a modified surface, and the outer surface and one end portion 14 a of the elastic attachment plate 14 are bonded to each other by an adhesive 15. It should be noted that the bonding between the one end portion of the mounting film material 21 and the film body 4 may be performed by bonding or stitching instead of the welding W. Further, all or a part of the outer surface other than the outer surface of the other end portion of the mounting film material 21 may be a modified surface as described above.

上記取付膜材21は、上記膜体4につき説明したものと同様のものが適用可能である。この場合、これら膜体4と取付膜材21とは互いに同構成、同材質であることが好ましい。   The same attachment film material 21 as that described for the film body 4 is applicable. In this case, it is preferable that the film body 4 and the attachment film material 21 have the same configuration and the same material.

ここで、上記取付膜材21は、これを所望の大きさや所望の形状に加工したり、切断したりすることが容易にできるものであるため、当該太陽光発電装置1における太陽電池取付構造に、上記のような取付膜材21を用いたことにより、膜体4への太陽電池5の取り付け作業が容易にできると共に、太陽電池5の取り替え作業も容易にできる。   Here, since the attachment film material 21 can be easily processed into a desired size or a desired shape, or can be cut, the solar battery mounting structure in the solar power generation device 1 can be used. By using the attachment film material 21 as described above, it is possible to easily attach the solar cell 5 to the film body 4 and to easily replace the solar cell 5.

また、上記弾性取付板14は、通常、ゴム材製であるため、この弾性取付板14と上記膜体4や太陽電池5とを溶着や縫着により互いに接合することは事実上困難である。そこで、上記したように、取付膜材21の他端部の外面を改質面としてこの外面と上記弾性取付板14の一端部14aとを互いに接着したのであり、これにより、上記弾性取付板14の一端部14aと取付膜材21の他端部とを強固に接着することができる。よって、上記膜体4への太陽電池5の取り付けが強固になされて、これら膜体4と太陽電池5との寿命の向上が、より確実に達成される。   Further, since the elastic mounting plate 14 is usually made of a rubber material, it is practically difficult to join the elastic mounting plate 14 and the film body 4 or the solar cell 5 to each other by welding or sewing. Therefore, as described above, the outer surface of the other end portion of the mounting film material 21 is used as a modified surface, and this outer surface and one end portion 14a of the elastic mounting plate 14 are bonded to each other. Can be firmly bonded to the other end portion of the attachment film material 21. Therefore, the solar cell 5 is firmly attached to the film body 4, and the life of the film body 4 and the solar cell 5 is improved more reliably.

ところで、固定側部材2に張設される膜体4に対し、上記弾性取付板14を接着させる接着作業は、熟練を要して煩雑な作業である。   By the way, the adhering operation for adhering the elastic mounting plate 14 to the film body 4 stretched on the stationary member 2 is a complicated operation requiring skill.

そこで、上記構成のように取付膜材21を設けたのであり、これによれば、上記取付具6により膜体4に太陽電池5を取り付ける取り付け作業をする場合には、例えば、まず、工場等の作業性の良いところで、弾性取付板14と、太陽電池5および取付膜材21とを接着剤15により接着してこれらの組み合わせ体5,14,21を形成し、次に、持ち運び可能な溶着機の熱風や熱板を用い、もしくは縫着機を用いて、上記組み合わせ体5,14,21を固定側部材2に張設された膜体4や張設前の膜体4の表面に対し溶着Wや縫着により接合することができる。   Therefore, the attachment film material 21 is provided as in the above configuration. According to this, when the attachment work for attaching the solar cell 5 to the film body 4 by the attachment 6 is performed, for example, first, a factory or the like Where the workability is good, the elastic mounting plate 14, the solar cell 5 and the mounting film material 21 are bonded together with an adhesive 15 to form a combined body 5, 14, 21, and then portable welding Using the hot air or hot plate of the machine, or using a sewing machine, the combined body 5, 14, 21 is applied to the surface of the film body 4 stretched on the stationary member 2 or the surface of the film body 4 before being stretched. It can be joined by welding W or sewing.

よって、接着作業に係る上記組み合わせ体5,14,21の形成が作業性の良いところで容易にでき、しかも、上記した溶着Wや縫着の作業は、持ち運び可能な溶着機や縫着機を用いることにより、接着作業に比べ多くの熟練を要せず比較的容易にできることから、その分、上記膜体4への太陽電池5の取り付け作業が容易にできる。   Therefore, the formation of the combined bodies 5, 14, and 21 relating to the bonding work can be easily performed in a good workability, and the above-described welding W and sewing work use a portable welding machine or sewing machine. Accordingly, since a lot of skill is not required as compared with the bonding operation, it can be relatively easily performed, and accordingly, the operation of attaching the solar cell 5 to the film body 4 can be facilitated.

本発明をより詳細に説明するために、その実施例4を添付の図1(d)に従って説明する。   In order to describe the present invention in more detail, Example 4 will be described with reference to FIG.

図において、前記実施例3に加え、上記取付具6は、上記太陽電池5と弾性取付板14の他端部14bとの間に介設され、上記太陽電池5の表面材と同材質の樹脂フィルム製の他の取付膜材23を有している。この他の取付膜材23は、太陽光発電装置1の平面視で、上記弾性取付板14と同様の長方形の枠形状とされている。この他の取付膜材23の面方向(長手方向各部の幅方向)の一端部である内端縁部と上記太陽電池5とが互いに溶着Wにより接合される。一方、上記他の取付膜材23の他端部である外端縁部の外面が改質面とされ、この外面と上記弾性取付板14の他端部14bとが互いに接着剤15により接着されている。なお、上記した他の取付膜材23の一端部と太陽電池5との互いの接合は、上記溶着Wに代えて接着によるものであってもよい。また、上記他の取付膜材23の他端部の外面以外の外面の、全部もしくは一部を前記のような改質面にしてもよい。   In the figure, in addition to the third embodiment, the fixture 6 is interposed between the solar cell 5 and the other end 14b of the elastic mounting plate 14, and is made of the same material as the surface material of the solar cell 5. It has another attachment film material 23 made of a film. The other attachment film material 23 has a rectangular frame shape similar to that of the elastic attachment plate 14 in a plan view of the solar power generation device 1. The inner end edge portion which is one end portion in the surface direction (width direction of each portion in the longitudinal direction) of the other attachment film material 23 and the solar cell 5 are joined to each other by welding W. On the other hand, the outer surface of the outer edge which is the other end of the other mounting film material 23 is a modified surface, and the outer surface and the other end 14b of the elastic mounting plate 14 are bonded to each other by the adhesive 15. ing. In addition, the mutual joining of the one end part of the other mounting film member 23 and the solar cell 5 described above may be performed by bonding instead of the welding W. Further, all or a part of the outer surface other than the outer surface of the other end portion of the other attachment film material 23 may be the modified surface as described above.

上記他の取付膜材23は、上記膜体4につき説明したものと同様のものが適用可能である。この場合、これら膜体4と他の取付膜材23とは互いに同構成、同材質であることが好ましい。   As the other attachment film material 23, the same one as described for the film body 4 can be applied. In this case, it is preferable that the film body 4 and the other attachment film material 23 have the same configuration and the same material.

ここで、上記他の取付膜材23は、これを所望の大きさや所望の形状に加工したり、切断したりすることが容易にできるものであるため、当該太陽光発電装置1における太陽電池取付構造に、上記のような他の取付膜材23を用いたことにより、膜体4への太陽電池5の取り付け作業が容易にできると共に、太陽電池5の取り替え作業も容易にできる。   Here, since the other attachment film member 23 can be easily processed into a desired size or a desired shape, or can be cut, the solar battery attachment in the solar power generation device 1 is possible. By using the other attachment film material 23 as described above in the structure, the attachment work of the solar cell 5 to the film body 4 can be facilitated, and the replacement work of the solar battery 5 can be facilitated.

また、上記弾性取付板14は、通常、ゴム材製であるため、そのままの状態で、この弾性取付板14と上記他の取付膜材23とを溶着することは、材質上、困難である。そこで、この溶着に代えて、縫着することが考えられるが、この場合には糸を通す穿孔のために雨水が浸入し易くなったり強度低下が生じ易くなったりするおそれがある。このため、上記弾性取付板と上記取付膜材とを溶着や縫着により互いに接合することは事実上困難である。   Further, since the elastic mounting plate 14 is usually made of a rubber material, it is difficult in terms of material to weld the elastic mounting plate 14 and the other mounting film material 23 as they are. Therefore, instead of this welding, it is conceivable to sew. However, in this case, there is a risk that rainwater may easily enter due to perforation through which the thread passes, or that strength may be easily reduced. For this reason, it is practically difficult to join the elastic mounting plate and the mounting film material to each other by welding or sewing.

そこで、前記したように、取付膜材23の他端部の外面を改質面としてこの外面と上記弾性取付板14の他端部14bとを互いに接着したのであり、これにより、上記弾性取付板14の他端部14bと他の取付膜材23の他端部とを強固に接着することができ、上記膜体4への太陽電池5の取り付けが強固になされる。よって、前記したように外部荷重に基づき膜体4が伸長変形してこの膜体4から太陽電池5に負荷が与えられる場合に、上記膜体4から上記太陽電池5が剥離するなどの不都合の発生は防止される。この結果、これら膜体4と太陽電池5との寿命の向上が、より確実に達成される。   Therefore, as described above, the outer surface of the other end portion of the attachment film member 23 is used as a modified surface, and this outer surface and the other end portion 14b of the elastic attachment plate 14 are bonded to each other. 14 can be firmly bonded to the other end portion 14b of the other attachment film member 23, and the solar cell 5 can be firmly attached to the film body 4. Therefore, as described above, when the film body 4 expands and deforms based on an external load and a load is applied from the film body 4 to the solar cell 5, there is an inconvenience such as peeling of the solar cell 5 from the film body 4. Occurrence is prevented. As a result, the lifetime of the film body 4 and the solar cell 5 is improved more reliably.

ところで、前記したように、固定側部材2に張設される膜体4に対し、上記弾性取付板14を接着させる接着作業は、熟練を要して煩雑な作業である。   By the way, as described above, the bonding operation for bonding the elastic mounting plate 14 to the film body 4 stretched on the fixed side member 2 is a complicated operation requiring skill.

そこで、上記構成のように他の取付膜材23を設けたのであり、これによれば、上記取付具6により膜体4に太陽電池5を取り付ける取り付け作業をする場合には、例えば、まず、工場等の作業性の良いところで、弾性取付板14と、取付膜材21および他の取付膜材23とを接着剤15により接着し、かつ、上記他の取付膜材23と太陽電池5とを互いに溶着Wや接着により接合して他の組み合わせ体5,14,21,23を形成し、次に、前記した持ち運び可能な溶着機や縫着機を用いて、上記他の組み合わせ体5,14,21,23を固定側部材2に張設された膜体4や張設前の膜体4の表面に対し溶着Wや縫着により接合することができる。   Therefore, the other attachment film material 23 is provided as in the above configuration. According to this, when the attachment work for attaching the solar cell 5 to the film body 4 by the attachment 6 is performed, for example, first, In a place where workability is good such as in a factory, the elastic mounting plate 14 is bonded to the mounting film material 21 and the other mounting film material 23 with the adhesive 15, and the other mounting film material 23 and the solar cell 5 are bonded together. The other combined bodies 5, 14, 21 and 23 are formed by welding to each other by welding W or adhesion, and then the other combined bodies 5, 14 are used by using the above-described portable welding machine or sewing machine. , 21, 23 can be joined to the surface of the film body 4 stretched on the stationary member 2 or the surface of the film body 4 before being stretched by welding W or sewing.

よって、接着作業に係る上記他の組み合わせ体5,14,21,23の形成が作業性の良いところで容易にでき、しかも、上記した溶着Wや縫着の作業は、持ち運び可能な溶着機や縫着機を用いることにより、接着作業に比べ多くの熟練を要せず比較的容易にできることから、その分、上記膜体4への太陽電池5の取り付け作業が容易にできる。   Therefore, the formation of the other combined bodies 5, 14, 21, 23 relating to the bonding work can be easily performed at a good workability, and the welding W and the sewing work described above can be performed with a portable welding machine or a sewing machine. By using the dressing machine, it is possible to relatively easily do not require much skill as compared with the bonding work, and accordingly, the work of attaching the solar cell 5 to the film body 4 can be facilitated.

本発明をより詳細に説明するために、その実施例5を添付の図3(a)に従って説明する。   In order to describe the present invention in more detail, Example 5 will be described with reference to FIG.

図において、前記実施例4を参照して、上記弾性取付板14の一端部14aが断面C字形状の係止部26とされている。そして、ロープや棒状ゴム等の可撓性長尺材25により厚さが大きくされた上記取付膜材21の他端部が上記係止部26に係止されている。また、上記弾性取付板14の他端部14bが断面C字形状の係止部27とされている。そして、上記と同様の長尺材25により厚さが大きくされた他の取付膜材23の他端部とが上記係止部27に係止されている。   In the figure, referring to the fourth embodiment, one end portion 14a of the elastic mounting plate 14 is a locking portion 26 having a C-shaped cross section. Then, the other end portion of the attachment film material 21 whose thickness is increased by the flexible long material 25 such as a rope or a rod-like rubber is locked to the locking portion 26. The other end portion 14b of the elastic mounting plate 14 is a locking portion 27 having a C-shaped cross section. And the other end part of the other attachment film | membrane material 23 thickened with the long material 25 similar to the above is latched by the said latching | locking part 27. As shown in FIG.

ここで、上記弾性取付板14の一端部14aに形成された一方の係止部26は、その長手方向の端部から上記取付膜材21の他端部を嵌入させて係止可能にさせるようになっている。また、上記弾性取付板14の他端部14bに形成された他方の係止部27は、その長手方向の端部から上記他の取付膜材23の他端部を嵌入させて係止可能にさせるようになっている。   Here, the one locking portion 26 formed on the one end portion 14a of the elastic mounting plate 14 is fitted into the other end portion of the mounting film material 21 from the end portion in the longitudinal direction so as to be locked. It has become. Further, the other locking portion 27 formed on the other end portion 14b of the elastic mounting plate 14 can be locked by inserting the other end portion of the other mounting film material 23 from the longitudinal end portion thereof. It is supposed to let you.

また、上記弾性取付板14の一端部14aと他端部14bとの各係止部26,27の引張弾性率E(MPa)の値は、弾性取付板14の前記面方向の中途部のそれよりも大きくされている。これにより、上記弾性取付板14の一端部14aと他端部14bとの各係止部26,27が高硬度にされる一方、上記弾性取付板14の中途部の弾性変形量が大きくなることとされている。   Further, the value of the tensile elastic modulus E (MPa) of each of the locking portions 26 and 27 between the one end portion 14a and the other end portion 14b of the elastic mounting plate 14 is that of the middle portion of the elastic mounting plate 14 in the surface direction. Has been bigger than. As a result, the locking portions 26 and 27 between the one end portion 14a and the other end portion 14b of the elastic mounting plate 14 are made to have high hardness, while the elastic deformation amount in the middle portion of the elastic mounting plate 14 is increased. It is said that.

特に、上記弾性取付板14の一端部14aおよび、または他端部14bの各係止部26,27の引張弾性率Eの値を上記弾性取付板14の中途部のそれよりも大きくする場合において、このように各引張弾性率Eの値が互いに相違する上記各係止部26,27と弾性取付板14の中途部とは、上記弾性取付板14の押し出し型などの形成型により一体的に容易に形成できる。よって上記取付具6による膜体4への太陽電池5の取り付け作業が容易にできると共に、上記取付膜材21,23の他端部を、上記弾性取付板14に対し強固に係止することが可能となる。   In particular, in the case where the value of the tensile elastic modulus E of each of the locking portions 26 and 27 of the one end portion 14a and / or the other end portion 14b of the elastic mounting plate 14 is made larger than that of the middle portion of the elastic mounting plate 14. The locking portions 26 and 27 and the middle portion of the elastic mounting plate 14 having different values of the respective tensile elastic moduli E are integrally formed by a forming die such as an extrusion die of the elastic mounting plate 14. Can be easily formed. Therefore, it is possible to easily attach the solar cell 5 to the film body 4 by the fixture 6 and to firmly lock the other end portions of the attachment film materials 21 and 23 to the elastic mounting plate 14. It becomes possible.

なお、上記係止部26,27は、いずれか一方のみが設けられるようにしてもよい。   Note that only one of the locking portions 26 and 27 may be provided.

上記構成によれば、上記取付具6による膜体4への太陽電池5の取り付け作業において、例えば、予め、膜体4に上記取付膜材21の一端部を接合しておき、その後、上記固定側部材2への膜体4の張設の前、後のいずれかにおいて、上記取付膜材21の他端部に、太陽電池5を取り付けた弾性取付板14の一端部14aを上記一方の係止部26により係止させることができる。よって、上記膜体4への太陽電池5の取り付け作業の自由度が向上すると共に、上記一方の係止部26により上記膜体4への太陽電池5の取り付け作業が極めて容易にできる。   According to the above configuration, in the operation of attaching the solar cell 5 to the film body 4 by the fixture 6, for example, one end of the attachment film material 21 is bonded to the film body 4 in advance, and then the fixing is performed. Either before or after the film body 4 is stretched on the side member 2, the one end portion 14 a of the elastic mounting plate 14 to which the solar cell 5 is attached is attached to the other end portion of the mounting film material 21. It can be locked by the stopper 26. Therefore, the degree of freedom in attaching the solar cell 5 to the film body 4 is improved, and the attaching operation of the solar cell 5 to the film body 4 can be extremely facilitated by the one locking portion 26.

また、上記取付具6による膜体4への太陽電池5の取り付け作業において、例えば、予め、膜体4に上記取付膜材21の一端部を接合すると共に、この取付膜材21の他端部に弾性取付板14の一端部14aを上記一方の係止部26により係止させておき、その後、上記固定側部材2への膜体4の張設の前、後のいずれかにおいて、上記弾性取付板14の他端部14bに、太陽電池5を取り付けた上記他の取付膜材23の他端部を上記他方の係止部27により係止させることができる。よって、上記膜体4への太陽電池5の取り付け作業の自由度が向上すると共に、上記他方の係止部27により上記膜体4への太陽電池5の取り付け作業が極めて容易にできる。   In addition, in the operation of attaching the solar cell 5 to the film body 4 by the fixture 6, for example, one end portion of the attachment film material 21 is joined to the film body 4 in advance, and the other end portion of the attachment film material 21. The one end portion 14a of the elastic mounting plate 14 is locked by the one locking portion 26, and then the elastic body plate is stretched either before or after the film body 4 is stretched to the fixed side member 2. The other end portion of the other attachment film member 23 to which the solar cell 5 is attached can be engaged with the other end portion 14 b of the attachment plate 14 by the other engagement portion 27. Therefore, the degree of freedom in attaching the solar cell 5 to the film body 4 is improved, and the attaching operation of the solar cell 5 to the film body 4 can be extremely facilitated by the other engaging portion 27.

また、前記したように、上記係止部26,27の引張弾性率(MPa)を、上記弾性取付板の上記面方向における中途部の引張弾性率(MPa)の値よりも大きくしている。   Further, as described above, the tensile elastic modulus (MPa) of the locking portions 26 and 27 is set larger than the value of the tensile elastic modulus (MPa) of the midway part in the surface direction of the elastic mounting plate.

このため、上記弾性取付板14には必要な弾性性能が維持される一方、上記した係止部26,27による弾性取付板14への取付膜材21,23の他端部の係止が強固になされることから、上記係止部26,27による膜体4への太陽電池5の取付強度が十分に確保される。よって、前記したように、係止部26,27により膜体4への太陽電池5の取り付け作業が容易にできるものでありながら、前記したように外部荷重に基づき膜体4が伸長変形してこの膜体4から太陽電池5に負荷が与えられる場合に、上記膜体4から上記太陽電池5が剥離するなどの不都合の発生は防止される。この結果、これら膜体4と太陽電池5との寿命の向上が達成される。   Therefore, the elastic mounting plate 14 maintains necessary elastic performance, while the locking portions 26 and 27 are firmly locked to the elastic mounting plate 14 at the other end portions of the mounting film materials 21 and 23. Therefore, the mounting strength of the solar cell 5 to the film body 4 by the locking portions 26 and 27 is sufficiently ensured. Therefore, as described above, the attachment of the solar cell 5 to the film body 4 can be facilitated by the locking portions 26 and 27, but the film body 4 is extended and deformed based on the external load as described above. When a load is applied from the film body 4 to the solar cell 5, inconveniences such as peeling of the solar cell 5 from the film body 4 are prevented. As a result, the lifetime of the film body 4 and the solar cell 5 is improved.

本発明をより詳細に説明するために、その実施例6を添付の図3(b)に従って説明する。   In order to describe the present invention in more detail, Example 6 will be described with reference to the attached FIG.

図において、前記実施例5を参照して、上記弾性取付板14の一端部14aと他端部14bとにはそれぞれ断面C字形状の係止部26,27が接着され、これら各係止部26,27は上記太陽電池5の外端縁部に沿って長く延びている。これら各係止部26,27は樹脂製とされるが金属製であってもよい。   In the figure, referring to the fifth embodiment, the one end portion 14a and the other end portion 14b of the elastic mounting plate 14 are bonded with locking portions 26 and 27 having a C-shaped cross section, respectively. 26 and 27 extend long along the outer edge of the solar cell 5. Each of the locking portions 26 and 27 is made of resin, but may be made of metal.

ここで、上記弾性取付板14の一端部14aに接着された一方の係止部26は、その長手方向の端部から上記取付膜材21の他端部を嵌入させて係止可能にさせるようになっている。また、上記弾性取付板14の他端部14bに接着された他方の係止部27は、その長手方向の端部から上記他の取付膜材23の他端部を嵌入させて係止可能にさせるようになっている。   Here, the one locking portion 26 bonded to the one end portion 14a of the elastic mounting plate 14 is fitted into the other end portion of the mounting film material 21 from the end portion in the longitudinal direction so as to be locked. It has become. Further, the other locking portion 27 bonded to the other end portion 14b of the elastic mounting plate 14 can be locked by inserting the other end portion of the other mounting film material 23 from the longitudinal end portion thereof. It is supposed to let you.
