  In addition, in this section, the reference numerals and drawing numbers appended to the above terms are not intended to limit the technical scope of the present invention to the “Example” section and the contents of the drawings described later.

  The effects of the present invention are as follows.

According to the first aspect of the present invention, there is provided 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 attaching the solar cell to the film body 4 In a solar cell mounting structure to a film body provided with a tool,
The fixture extends along the outer edge portion of the solar cell, and one end edge portion in the width direction is fixed to the film body, and along the outer edge portion of the solar cell. And extending along the first and second attachment film bodies, one end edge in the width direction being fixed to the outer edge of the solar cell, and the first and second attachment film bodies. A locking body that locks the other end edges of the first and second mounting film bodies by relative movement in the longitudinal direction with respect to the second mounting film body.

  For this reason, when performing the attachment operation | work which attaches a solar cell with respect to the film body stretched by the said fixed side member, while attaching the 1st attachment film body to the said film body first, it is 2nd to the said solar cell. Secure the mounting membrane. Next, relative to the first and second mounting film bodies, the locking body of the mounting tool is moved relative to the longitudinal direction of the first and second mounting film bodies, and each other end of the first and second mounting film bodies is moved by the locking body. Lock the edges together. Then, the operation of attaching the solar cell to the film body can be completed.

  And what has troublesome work like the adhering of the 1st attachment film body to the above-mentioned film body and the adhering of the 2nd attachment film body to a solar cell should just be a place with good workability, such as a factory. On the other hand, the locking operation by the locking body between the first and second attachment film bodies can be performed by a simple operation of relatively moving the locking body as described above. For this reason, the above-described locking operation can be easily performed even in places where workability is poor, such as field work. Therefore, according to the said invention, the attachment operation | work of the solar cell to a film body can be done easily.

  Further, as described above, the other end edge portions of the first and second mounting film bodies are locked by the locking body in the longitudinal direction with respect to the first and second mounting film bodies. Achieved by relative movement of the body. For this reason, when the first and second attachment film bodies are locked together by the locking body, the locking body is in the locked state against an external force acting in a direction perpendicular to the locking body. Strongly oppose to hold.

  Here, normally, in addition to the weight of the film body, a large tensile force is given to the film body in the plane direction by the mass of the solar cell and the wind pressure. For this reason, at least a part of the large tensile force tends to be applied to the fixture. And the tension | tensile_strength force which is going to be given to a fixture in this way mainly acts as an external force in the direction orthogonal to the latching body which this fixture has. Therefore, the attachment of the solar cell to the film body can be made strong by the fixture that strongly opposes the external force in this direction.

  In the invention of claim 2, the outer edge portion of the solar cell extends in the horizontal direction.

  For this reason, the first and second attachment film bodies of the fixture also extend in the horizontal direction as the outer edge portion of the solar cell extends in the horizontal direction. Locking of the fixture by the locking body is achieved by relatively moving the locking body in the horizontal direction with respect to the first and second mounting film bodies.

  Therefore, if the solar cell is attached to the film body extending in the vertical direction, the first and second attachment film bodies are moved relative to each other in the horizontal direction as described above. When locked by the locking body, the solar cell's own weight acts in a direction perpendicular to the locking body of the fixture, and the solar cell's own weight is strengthened by the locking body. It is supported stably. For this reason, the operation of attaching the solar cell to the film body can be performed more easily.

  According to a third aspect of the present invention, the locking body is formed of a bar extending along the first and second attachment film bodies, and the bar is formed along the longitudinal direction thereof. Each has a pair of locking grooves each having a C-shaped concave shape, and a thick portion formed on each of the other end edges of the first and second mounting film bodies and locked to the locking grooves. doing.

  For this reason, the bar of the locking body of the fixture and the locking groove can be easily formed by extrusion molding. Therefore, the attachment of the solar cell to the film body using the fixture can be achieved at a low cost with a simple configuration.

  According to a fourth aspect of the present invention, each of the locking grooves is formed in one flat surface of the outer surface of the bar material as viewed in a cross section of the bar material, and the surface of the film body and the outer surface of the bar material are formed. The flat surfaces are close to each other.

  For this reason, since the opening of each locking groove formed in the locking body of the fixture is blocked by the film body, the locking groove is prevented from being easily seen in appearance. Therefore, the appearance of the assembly composed of the film body, the solar cell, and the fixture is maintained satisfactorily, and the entry of rainwater and the like into the locking grooves is suppressed.

  According to a fifth aspect of the present invention, each crossing angle formed by the two flat surfaces sandwiching the one flat surface and the flat surfaces among the outer surfaces of the bar is made acute.

  Here, as described above, when the solar cell is attached to the film body with the fixture, the bar of the locking body included in the fixture projects outward from the surface of the film body.

  However, according to the invention, since the intersection angle formed by the flat surface close to the film body and the other flat surface sandwiching the flat surface among the outer surfaces of the bar material is an acute angle, the intersection angle is set to a right angle or more. In comparison, the surface of the assembly composed of the film body, the solar cell, and the fixture can be made smoother. Therefore, the drainage of the surface of the assembly can be improved accordingly, and the generation of wind noise can be suppressed.

  According to a sixth aspect of the present invention, there is provided a connector for connecting the outer edges of the solar cells arranged side by side along the surface of the film body, the connecting tools being connected to the outer edges of the solar cells. Each of the second attachment film bodies to which one end edge portion is fixed, and another engagement body for engaging the other end edge portions of both the second attachment film bodies are provided.

  For this reason, in the case where a plurality of solar cells are arranged side by side along the surface of the film body and these are connected by the connection tool, the connection tool is a second mounting film body that is a component of the fixture, It is possible to use the bar material in which a locking groove for locking the thick portion of the second attachment film body is formed. Therefore, since parts can be shared between the mounting tool and the connecting tool, the mounting of a plurality of solar cells to the film body using the mounting tool or the connecting tool is reduced by a simple structure. Can be achieved.

  Briefly, the mounting operation for attaching the solar cell 10 to the film body 4 stretched on the fixed side member 3 will be described. As a first example, first, in the factory, the fixture 11 and the coupling tool 12 are attached to the film body 4. Each solar cell 10 is attached by. Next, the combination of these 4, 10 to 12 is attached to the fixed side member 3. Then, the installation work of each of the solar cells 10 is finished.

  As a second example, first, in the factory, the first attachment film body 15 of the fixture 11 is fixed to the film body 4, while the second attachment film body 16 of the fixture 11 is fixed to the solar cell 10. . Next, a combination of the film body 4 and the first attachment film body 15 of the fixture 11 is attached to the fixed side member 3. Next, each solar cell 10 is attached to the film body 4 by using the second attachment film body 16 and the locking body 17 of the fixture 11 with respect to the first attachment film body 15 of the fixture 11. Moreover, both the solar cells 10 and 10 are connected by the said connector 12 with this. Then, the installation work of these solar cells 10 is finished.

  As a third example, first, the film body 4 is attached to the stationary member 3 to form the building 1. Next, as a retrofit, the solar cells 10 are attached to the surface of the film body 4 by the fixture 11 and the connector 12. Then, the installation work of these solar cells 10 is finished.

  According to the said structure, the said attachment tool 11 is extended along the outer edge part of the said solar cell 10, and the band-shaped 1st attachment film body 15 to which the one end edge part 15a of the width direction adheres to the said film body 4 is demonstrated. And a belt-shaped second attachment film body 16 extending along the outer edge portion of the solar cell 10 and having one end edge portion 16a in the width direction fixed to the outer edge portion of the solar cell 10, and the first The first and second attachment film bodies 15 and 16 extend along the second attachment film bodies 15 and 16 and are moved relative to the first and second attachment film bodies 15 and 16 in the longitudinal direction thereof. It has the latching body 17 which latches the other end edge parts 15b and 16b.

  For this reason, when performing the attachment operation | work which attaches the solar cell 10 with respect to the film body 4 stretched by the said fixed side member 3, first, while fixing the 1st attachment film body 15 to the said film body 4, The second attachment film body 16 is fixed to the solar cell 10. Next, the locking body 17 of the mounting tool 11 is moved relative to the first and second mounting film bodies 15 and 16 in the longitudinal direction, and the locking body 17 causes the first and second mounting film bodies 15 and 16 to move relative to each other. The other end edges 15b and 16b of the film bodies 15 and 16 are locked together. Then, the operation of attaching the solar cell 10 to the film body 4 can be completed.

  If the work is troublesome, such as the fixing of the first mounting film 15 to the film body 4 and the fixing of the second mounting film 16 to the solar cell 10 as described above, it may be a good place such as a factory. Good. On the other hand, the locking operation by the locking body 17 between the first and second mounting film bodies 15 and 16 is performed by a simple operation of moving the locking body 17 relative to each other as described above, compared to fastening and bonding. it can. For this reason, the above-described locking operation can be easily performed even in places where workability is poor, such as field work. Therefore, according to the said structure, the attachment operation | work of the solar cell 10 to the film body 4 can be done easily.

  Moreover, in said case, the 1st, 2nd attachment film bodies 15 and 16 are latched by the latching body 17 of the said fixture 11 so that engagement / disengagement is possible.

  For this reason, if the engaging / disengaging work is performed by the locking body 17, the solar cell 10 already attached to the film body 4 is removed and repaired, or replaced with another solar cell 10 such as a new one. Is easy and beneficial.

  As described above, the other end edge portions 15b, 16b of the first and second mounting film bodies 15, 1 are locked by the locking body 17, and the first and second mounting film bodies 15, This is achieved by the relative movement of the locking body 17 in its longitudinal direction with respect to 16. Therefore, when the first and second attachment film bodies 15 and 16 are locked by the locking body 17, the locking body 17 is subjected to an external force acting in a direction perpendicular to the locking body 17. On the other hand, it strongly opposes so that the said locked state may be maintained.

  Here, normally, in addition to the weight of the film body 4, a large tensile force is given to the film body 4 in the surface direction by the mass of the solar cell 10 and the wind pressure. For this reason, at least a part of the large tensile force tends to be applied to the fixture 11. And the tensile force which is going to be given to the fixture 11 in this way acts mainly as an external force in the direction orthogonal to the locking body 17 which this fixture 11 has. Therefore, the attachment of the solar cell 10 to the film body 4 can be made strong by the fixture 11 that strongly opposes the external force in this direction.

  Further, as described above, the outer edge portion of the solar cell 10 extends in the horizontal direction.

  For this reason, as the outer edge portion of the solar cell 10 extends in the horizontal direction, the first and second attachment film bodies 15 and 16 of the fixture 11 also extend in the horizontal direction. Locking the film bodies 15 and 16 by the locking body 17 of the fixture 11 is achieved by moving the locking body 17 in the horizontal direction relative to the first and second mounting film bodies 15 and 16. Is done.

  Therefore, if the solar cell 10 is to be attached to the vertical film body 4b of the film body 4 extending in the vertical direction, as described above, the first and second mounting film bodies 15 and 16 are used as described above. Is locked by a locking body 17 that moves relative to these 15 and 16 in the horizontal direction, the weight of the solar cell 10 acts in a direction perpendicular to the locking body 17 of the fixture 11. As a result, the dead weight of the solar cell 10 is firmly and stably supported by the locking body 17. For this reason, the subsequent mounting operation of the solar cell 10 to the film body 4 can be performed more easily.

  Further, as described above, the locking body 17 is formed along the longitudinal direction of the bar 19 extending along the first and second attachment film bodies 15 and 16 and the longitudinal direction of the bar 19. Each cross section of each direction is formed in a pair of locking grooves 20 and 20 each having a C-shaped concave shape and each of the other end edges 15b and 16b of the first and second mounting film bodies 15 and 16, respectively. It has a thick portion 21 that is locked in the locking groove 20.

  For this reason, the bar 19 and the locking groove 20 of the locking body 17 of the fixture 11 can be easily formed by extrusion molding. Therefore, the attachment of the solar cell 10 to the film body 4 using the attachment 11 can be achieved at a low cost with a simple configuration.

  Further, as described above, each of the locking grooves 20 is formed in one flat surface 25a of the outer surface 25 of the bar 19 as viewed in the cross section of the bar 19, and the surface of the film body 4 and the The flat surface 25a of the outer surface 25 of the bar 19 is brought close to each other.

  For this reason, since the opening of each locking groove 20 formed in each locking body 17 included in the mounting tool 11 and the coupling tool 12 is blocked by the film body 4, each locking groove 20 has an appearance. It is prevented from being easily seen. Therefore, the appearance of the assembly composed of the film body 4, the solar cell 10, the attachment tool 11, and the connection tool 12 is maintained well, and entry of rainwater or the like into the locking grooves 20 is suppressed. Is done.

  Further, as described above, of the outer surface 25 of the bar 19, each crossing angle θ formed by the two other flat surfaces 25 c and 25 c sandwiching the one flat surface 25 a and the flat surface 25 a is an acute angle. Yes.

  Here, as described above, when the plurality of solar cells 10 are attached to the film body 4 with the attachment 11 or the connection tool 12, the rod of the locking body 17 included in the attachment 11 or the connection tool 12. The material 19 protrudes outward from the surface of the film body 4.

  However, according to the above configuration, the intersection angle θ formed by the flat surface 25a close to the film body 4 and the other flat surfaces 25c and 25c sandwiching the flat surface 25a in the outer surface 25 of the bar 19 is an acute angle. Therefore, the surface of the assembly composed of the film body 4, the solar cell 10, the fixture 11, and the connector 12 can be made smoother than when the intersection angle θ is set to a right angle or more. Therefore, the drainage of the surface of the assembly can be improved accordingly, and the generation of wind noise can be suppressed.

  Further, as described above, the connecting tool 12 that connects the outer edges of the solar cells 10 and 10 that are arranged side by side along the surface of the film body 4 is provided. The second attachment film body 16 having one end edge portion 16a fixed to the outer edge portion of the battery 10, and another engagement body for engaging the other end edge portions 16b of the second attachment film bodies 16 and 16. 27.

  For this reason, when a plurality of solar cells 10, 10 are arranged side by side along the surface of the film body 4 and are connected by the connector 12, the connector 12 is a component of the fixture 11. The bar 19 in which the second mounting film body 16 and the locking grooves 20 and 20 for locking the thick portion 21 of the second mounting film body 16 are formed can be used. Therefore, since parts can be shared between the fixture 11 and the connector 12, attachment of the plurality of solar cells 10 to the film body 4 using the fixture 11 and the connector 12 is accordingly performed. It can be achieved at a low cost with a simple configuration.
