  By the way, in the installation structure shown in FIG. 19, as shown in FIG. 21, the subunit 10 is lifted by the forklift 100, approached from the front side of the gantry 20, and the mounting inclined surfaces 23a, 23a of the adjacent vertical bars 23,23. The mounting end portions 12e and 12e on both sides of the two front and rear support rails 12 and 12 fixed to the back surface of the solar cell module body 11 are attached to the two front and rear (a total of four) receiving portions 26 to 26 attached to the front and rear. After fitting, the installation end portions 12e and 12e of the support rails 12 and 12 are fixed to the receiving portions 26 to 26, respectively, by a fixture (not shown).

  In this case, the vertical beam 23 is inclined at a predetermined angle (an angle at which sunlight can be received most efficiently) θ1, and the subunit 10 lifted by the forklift 100 is slightly inclined by the forklift 100. Although it can be held, the inclination angle (tilt angle) θ2 is extremely smaller than the inclination angle θ1 of the vertical beam 23. Therefore, when installing the subunit 10 on the vertical rails 23, 23, first, the installation ends 12e, 12e on both sides of the support rail 12 fixed to the upper side of the inclination of the subunit 10 are connected to the vertical rails 23, 23. Then, the forklift 100 is lowered and the installation ends 12e and 12e of the support rail 12 on the upper side of the tilt are moved upward. The forklift 100 is further lowered by being fitted into the receiving portions 26 and 26 on the side, so that the subunit 10 is rotated downward with the support rail 12 on the inclined upper side as a rotation fulcrum. The receiving end 2 attached to the inclined lower side of the vertical bars 23, 23 with the installation end portions 12e, 12e on both sides of the support rail 12 fixed to the inclined lower side. , It will be fitted into the 26.

  At the time of this installation work, as shown in FIG. 22, for the driver of the forklift 100, the vertical bars 23, 23 are hidden by the subunit 10, and slightly from the edge of the mounting inclined surface 23 a of the vertical bar 23. The end of the receiving portion 26 that protrudes in the direction is almost invisible. Further, the installation end portion 12e of the support rail 12 slightly protruding from both ends of the subunit 10 is almost invisible (or very difficult to see).

  Therefore, in this situation, accurately positioning the installation ends 12e and 12e of the support rail 12 of the subunit 10 at the upper positions of the receiving portions 26 and 26 attached to the vertical bars 23 and 23, This is extremely difficult for the driver of the forklift 100.

  Therefore, conventionally, auxiliary workers are arranged beside the vertical rails 23 and 23, respectively, and the installation end portions 12e and 12e of the support rail 12 of the sub unit 10 are vertically moved while giving detailed instructions to the driver of the forklift 100. It is necessary to accurately position the receiving portions 26 and 26 attached to the crosspieces 23 and 23 at an upper position.

  Therefore, there is a problem that it takes time for installation work and it is necessary to increase the number of workers for installation.

  The present invention was devised to solve such problems. The purpose of the present invention is to provide a solar cell module mount that enables or facilitates the installation work of a solar cell module that is a subunit even for a forklift driver alone. It is in providing the installation method of a solar cell module, and a solar power generation system.

  In order to solve the above problems, a solar cell module mount of the present invention is a solar cell module mount that supports a solar cell module including a support member fixed to the back surface of the solar cell module body, and is provided on the installation surface.

  According to the present invention, when the solar cell module is placed from the inclined front side on the receiving portion attached to the inclined beam portion by increasing the length of the upper side plate, the upper side plate supports the support member. By serving as a guide plate for guiding up to the installation plate, it is not necessary to accurately position the support member and the installation plate, and the installation operation can be performed smoothly. In addition, when the solar cell module is placed on the gantry, the placement position can be determined by bringing the support member into contact with the upper side plate, which facilitates the alignment of the solar cell module to the gantry. Can be installed more smoothly. That is, workability is improved.

  In the solar cell module mount of the present invention, the height of the upper side plate relative to the mounting inclined surface may be higher than the height of the lower side plate relative to the mounting inclined surface.

  According to this configuration, by making the height of the upper side plate relative to the mounting inclined surface higher than the height of the lower side plate relative to the mounting inclined surface, the solar cell module is moved in a substantially horizontal state from the front side of the mounting inclined surface. When approaching the crosspiece, it becomes easy for the support member fixed to the back surface of the solar cell module to approach or contact the upper side plate while avoiding contact with the lower side plate.

  Further, in the solar cell module mount of the present invention, the upper side plate is configured to extend away from the beam portion toward the inclined upper side of the beam portion.

  According to this configuration, since the upper side plate can be made sufficiently long, the region where the support member is guided, that is, the region where the support member is applied and positioned can be widened (long in the tilt direction). Therefore, even when the support member is slightly shifted and placed on the crosspiece, the support member can be reliably approached or brought into contact with the upper side plate of the receiving portion, and the upper side plate can be slid to the installation plate. It can be surely guided.

  Further, in the solar cell module mount of the present invention, the upper side plate may be formed in a curved shape that is recessed toward the crosspiece side from the side side to the tip side of the installation plate.

  According to this configuration, by forming the upper side plate in a curved shape, the support member in contact with the upper side plate can be smoothly guided to the installation plate while sliding on the upper side plate.

  According to this configuration, when the support member is placed on the receiving portion by providing the elastic member at the upper edge of the upper side plate, the back glass that is the back surface of the solar cell module body is the upper end of the upper side plate of the receiving portion. Even if it hits the edge, the elastic member becomes a cushion and can avoid direct contact with the upper edge of the back glass, so that the back glass can be prevented from being damaged.

  Moreover, in the solar cell module mount according to the present invention, the support member is arranged and fixed in parallel at a plurality of locations at predetermined intervals in a direction orthogonal to the one direction on the back surface of the solar cell module body. In addition, a plurality of the crosspieces are arranged in parallel with a certain interval in the one direction, and the support member is received over a pair of adjacent crosspieces, The mounting inclined surface of each of the crosspieces is configured to be provided at a plurality of locations with a predetermined interval in the other direction.

  According to this configuration, the support members are arranged at a plurality of locations (for example, two locations) in parallel, and the receiving portions are also provided at a plurality of locations (for example, two locations) at the same interval as the support members on the crosspieces that receive the support members. Thus, the solar cell module can be stably placed and fixed on the gantry.

  Further, in the solar cell module mount of the present invention, the solar cell module is arranged with a plurality of the solar cell module main bodies, the support members are bridged and fixed to the back surface of each solar cell module main body, and the support members Each solar cell module main body is connected.

  In this way, the solar cell module has a structure in which a plurality of solar cell module bodies are integrated by the support member, so that even a large-sized solar cell module can be quickly, accurately, and stably on the gantry. Can be fixed.

  Further, a solar cell module installation method according to the present invention is an installation method in which the solar cell module is installed using the solar cell module mount of each of the above configurations, and is inclined in the horizontal state or in the same direction as the crosspiece. Holding the solar cell module in a held state, and supporting the support member fixed to the back surface of the held solar cell module from the mounting inclined surface side to the pair of crosspieces; The step of bringing the support member on the upper side of the slope in the state of being opposed to the upper side plate of the receiving portion on the upper side of the slope of the mounting inclined surface, and the upper side plate of the support member on the upper side of the slope The solar cell module is lowered by lowering the entire solar cell module in a state where the solar cell module is brought into contact with or in contact with the solar cell module, with the portion contacting the upper side plate as a fulcrum. In the descending process and in the descending process, the support member on the upper side of the slope is slid on the upper side plate and slid to the installation plate, and the support member on the lower side of the tilt is mounted And placing on the installation plate of the receiving portion on the inclined lower side of the inclined surface.

  According to the present invention, when the solar cell module is mounted on the gantry, the mounting position can be determined by bringing the support member into contact with the upper side plate, so that the solar cell module can be easily aligned with the gantry. Thus, the subsequent installation work can be performed smoothly. That is, the workability of the installation work is improved.

  Moreover, in the installation method of the solar cell module which concerns on this invention, it is set as the structure which further includes the process of fixing the said support member mounted on the said installation board to the said receiving part with a fixing tool. According to the present invention, since the installation work can be performed smoothly, the subsequent fixing work can be easily performed.

  By using the solar cell module mount of the present invention, it is possible to provide a solar power generation system having excellent installation workability.

  Since the present invention is configured as described above, when the solar cell module is placed from the inclined front side on the receiving portion attached to the inclined beam portion, the upper side plate guides the support member to the installation plate. By fulfilling the role, it is not necessary to accurately position the support member and the installation plate, and the installation work can be performed smoothly. In addition, when the solar cell module is placed on the gantry, the placement position can be determined by bringing the support member into contact with the upper side plate, which facilitates the alignment of the solar cell module to the gantry. Therefore, installation work can be performed more smoothly and workability is improved.

  As shown in FIGS. 7 and 8, the support rail 12 includes a long main plate 12a, side plates 12b and 12b bent on both long sides in the short direction M of the main plate 12a, and side plates 12b. , 12b are folded inward at the lower side, and are further folded upward so as to have folded back reinforcing portions 12c, 12c. That is, the support rail 12 has a substantially lip groove steel shape (U-shaped cross-sectional shape) in cross-sectional shape. Further, in the support rail 12, the upper surface 12a1 of the main plate 12a is an adhesive surface to which an adhesive is applied, and the lower side of both end portions of the side plates 12b and 12b and both end portions of the folded reinforcing portions 12c and 12c are installed end portions 12e. 12e. The support rail 12 having such a configuration can be formed by punching and bending a steel plate and plating the surface.

  In the subunit 10 according to the present embodiment, the support rail 12 having the above configuration is arranged on the back surface of the solar cell module body 11 (here, the outer surface of the back glass 11c) along the lateral direction T of the solar cell module body 11. The arrangement is fixed.

  More specifically, in the subunit 10, a plurality (here, three) solar cell module bodies 11 to 11 are arranged in the horizontal direction T, and a plurality (here, two) support rails 12 are arranged. , 12 are arranged in parallel to each other at a certain interval in the vertical direction N perpendicular to the direction of the boundary between the solar cell module bodies 11, 11 adjacent to each other in the horizontal direction T. And the subunit 10 is the solar cell module main body 11 of the back surface (here outer surface of the back surface glass 11c) and the support rails 12 and 12 of each solar cell module main body 11-11 via the adhesive agent 30 (refer FIG. 6). The solar cell module main bodies 11 to 11 are connected and supported by the support rails 12 and 12 by being overlapped and bonded to the side surface. Here, a slight gap (for example, about 1 cm) may be provided between the solar cell module bodies 11 and 11 adjacent to each other in the lateral direction T from the viewpoint of avoiding damage due to mutual contact. The matching solar cell module bodies 11 to 11 may be brought into contact with each other. Further, as the adhesive 30, for example, a two-component silicone adhesive can be used.

  Thus, by arranging a plurality (here, two) of support rails 12 in parallel along the lateral direction T of the solar cell module body 11, when the subunit 10 is placed on the gantry 20, the vertical direction N The subunit 10 can be mounted and fixed on the gantry 20 stably without rattling.

  The support rails 12 are arranged in parallel along the horizontal direction T with a certain interval in the vertical direction N of the solar cell module main body 11, but in this embodiment, the back surface of the solar cell module main body 11 is arranged. In FIG. 5, the center line α (see FIG. 5) parallel to the horizontal direction T passing through the center position in the vertical direction N is provided at a position that is symmetric or substantially symmetric. More specifically, the arrangement position of the support rail 12 is a position that is brought inward in the vertical direction N by a predetermined distance t (see FIG. 5) from both end edges in the vertical direction N of the solar cell module body 11. ing.

  As described above, the support rails 12, 12 are disposed at positions that are located inward in the vertical direction N by a distance t from both end edges in the vertical direction N of the solar cell module body 11, so that the sun applied to the support rails 12, 12. The weight of the battery module body 11 can be distributed in a well-balanced manner, whereby the weight distribution to the support rails 12 and 12 can be made uniform.

  To illustrate specific numerical values, the solar cell module body 11 has a rectangular shape in plan view with a length in the vertical direction N of about 1400 mm and a length in the horizontal direction T of about 1000 mm. Each of the support rails 12 and 12 is disposed at a position close to each other by a distance t of about 300 mm from the both end edges in the vertical direction N of the solar cell module body 11 to the inner side in the vertical direction N. However, it is not limited to these numerical values.

  In addition, it is preferable that the arrangement | positioning position of the support rail 12 is made into the center position of the both-ends edge in the vertical direction N of the solar cell module main body 11, and the centerline (alpha). By doing so, the weight of the solar cell module main body 11 applied to the support rails 12 and 12 can be further distributed in a balanced manner, whereby the weight distribution to the support rails 12 and 12 can be made more uniform. Become.

  Further, as shown in FIG. 4, each support rail 12, 12 has a length d1 in the lateral direction X of the subunit 10, and a length in the lateral direction T of each of the solar cell module bodies 11 to 11 in the subunit 10. It is slightly longer than d2. The support rails 12 and 12 are bonded over substantially the entire area of the bonding portion of the solar cell module main bodies 11 to 11 in the sub unit 10 so that the bonding area with the solar cell module main bodies 11 to 11 is as large as possible. And the protrusion amount d3 of the both ends in the horizontal direction T of each support rail 12 and 13 which protruded from the both ends position in the horizontal direction T of each solar cell module main body 11-11 whole in the subunit 10 is mutually made to correspond. .

  In addition, as for each support rail 12 and 12, the length d1 of the horizontal direction T in the subunit 10 is the same as or substantially the same as the length d2 of the whole solar cell module main bodies 11-11 in the subunit 10 in the horizontal direction T2. It may be a length. In this case, the both end positions of the support rails 12 and 12 and the both end positions in the lateral direction T of each of the solar cell module main bodies 11 to 11 in the subunit 10 can be made to coincide with each other. Here, a slight gap (between the respective subunits 10 and 10 adjacent in the horizontal direction T (between the solar cell module bodies 11 at the left end or the right end in the horizontal direction T) from the viewpoint of mutual damage ( For example, about 1 cm) may be provided, or the subunits 10 and 10 adjacent to the horizontal direction T (the solar cell module body 11 at the left end or the right end in the horizontal direction T) may be brought into contact with each other. Further, similarly to the case of the horizontal direction T, damage due to mutual contact is avoided between the subunits 10 and 10 adjacent to each other in the vertical direction N (the solar cell module body 11 at the upper end or the lower end of the vertical direction N). A slight gap (for example, about 1 cm) may be provided from the viewpoint, and the subunits 10 and 10 adjacent to each other in the vertical direction N (the solar cell module body 11 at the upper end or the lower end in the vertical direction N) are brought into contact with each other. Also good.

<Description of receiving portion 25>
9A and 9B are a perspective view and a cross-sectional view showing a configuration example 1 of the receiving portion 25.

  The receiving portion 25 includes an installation plate 25a provided on the mounting inclined surface 23a of the vertical beam 23, an upper side plate 25b extending upward from the inclined upper side 25a1 of the installation plate 25a with respect to the mounting inclined surface 23a, A lower side plate 25c extending upward from the side 25a2 on the inclined lower side of the installation plate 25a with respect to the mounting inclined surface 23a. Further, the installation plate 25a is provided with a female screw hole 25e, which will be described later, in the center, and through holes 25h, 25h, which will be described later, are provided at symmetrical positions on both sides via the female screw hole 25e.

  In the above configuration, in the configuration example 1, the length m1 in the direction orthogonal to the inclined upper side 25a1 of the upper side plate 25b (that is, the inclined direction W) is the direction orthogonal to the inclined lower side 25a2 of the lower side plate 25c. In other words, (m1> m2) is configured to be longer than the length m2 in the inclination direction W.

  In this way, by increasing the length m1 of the upper side plate 25b, the sub unit 10 can be moved from the inclined front side (the left side in FIGS. 9A and 9B) to the receiving portion 25 provided to be inclined on the mounting inclined surface 23a. The upper side plate 25b can serve as a guide plate for guiding the support rail 12 of the subunit 10 to the installation plate 25a. Thereby, even if the support rail 12 of the subunit 10 is not accurately aligned on the installation plate 25a, it is sufficient that the support rail 12 of the subunit 10 is located at some position on the upper side plate 25b. Since accurate positioning is not necessary, installation work can be performed smoothly. Further, when the subunit 10 is placed on the gantry 20, the approximate placement position can be determined by bringing the support rail 12 into contact with the upper side plate 25 b of the receiving portion 25. (Accurately, it is easy to align with the vertical beam 23). From this point, the installation work can be performed more smoothly and the workability is improved.

  In the configuration example 1, the height h1 of the upper side plate 25b with respect to the mounting inclined surface 23a is configured to be higher than the height h2 of the lower side plate 25c with respect to the mounting inclined surface 23a (h1> h2).

  According to this configuration, when the subunit 10 is moved in a substantially horizontal state (indicated by a white arrow in FIG. 9B) and approaches the vertical rail 23 from the front side of the mounting inclined surface 23 a, the subunit 10 It becomes easy to make the support rail 12 fixed to the back surface of the upper plate 25b approach or contact the upper plate 25b while avoiding contact with the lower plate 25c.

  In this manner, the upper side plate 25b can be made sufficiently long by extending the upper side plate 25b away from the vertical beam 23 toward the inclined upper side in the inclination direction W of the vertical beam 23. The area where 12 is guided, that is, the area where the support rail 12 is applied to be positioned can be widened (long in the inclination direction W). Therefore, even when the support rail 12 is slightly displaced and placed on the vertical rail 23, the support rail 12 can be reliably approached or brought into contact with the upper side plate 25b of the receiving portion 25, and can be slid on the upper side plate 25b. Therefore, it is possible to reliably guide up to the installation plate 25a.

  Further, in the configuration example 1, the upper side plate 25b is formed in a curved shape that is recessed toward the vertical rail 23 side (that is, the mounting inclined surface 23a side) from the side 25a1 side to the tip side of the installation plate 25a. In this way, by forming the upper side plate 25b in a curved shape, the support rail 12 in contact with the upper side plate 25b can be smoothly guided to the installation plate 25a while sliding on the upper side plate 25b.

  10A and 10B show another configuration example (configuration example 2) of the receiving portion 25. 9A and 9B is different from the receiving portion 25 in the configuration example 1 shown in FIGS. 10A and 10B in that the upper side plate 25b is formed in a curved shape or linear. However, the other configurations are the same.

  FIG. 10C to FIG. 10E show still another configuration example (configuration example 3) of the receiving portion 25. In the receiving portion 25 of the configuration example 3, the receiving portion 25 of the configuration example 1 (or the receiving portion 25 of the configuration example 2) may be connected to the upper edge 25b1 of the upper side plate 25b with which the installation end portion 12e of the support rail 12 abuts. The elastic member 27 such as a rubber sheet is attached so as to be wound in a U-shaped cross section. Here, the elastic member 27 is preferably a member in which an adhesive and foamed rubber are laminated (for example, EC140 manufactured by Nitto Denko Corporation). The adhesive can be attached to the receiving portion, and the foamed rubber can protect the solar cell from the receiving portion when the solar cell module contacts the receiving portion.

  According to this configuration, as shown in FIG. 10E, the subunit 10 is moved in a substantially horizontal state (indicated by a white arrow in FIG. 10E) to move from the front side of the mounting inclined surface 23a to the vertical beam 23. When approaching or when the subunit 10 is slightly lowered from the approached state, the rear glass 11c, which is the rear surface of the subunit 10, is placed on the upper edge 25b1 of the upper side plate 25b of the receiving portion 25. Even if it hits (indicated by a solid line in FIG. 10E), the elastic member 27 can serve as a cushion to avoid direct contact with the upper edge 25b1, thereby preventing the back glass 11c from being damaged.

<Description of the installation method of the sub unit 10 to the gantry 20>
Next, a method of installing the subunit 10 on the gantry 20 will be described with reference to FIGS. 11A to 11F and FIGS. However, FIG. 11A thru | or FIG. 11F is explanatory drawing which shows an installation process typically, and FIG.12 and FIG.13 is explanatory drawing which shows a mode that the support rail 12 is inserted in the receiving part 25. FIG.

  First, as shown in FIG. 11A, the subunit 10 stored in a storage place (not shown) is lifted by the forklift 100 and held in a horizontal state or in a state inclined in the same direction as the vertical rail 23.

  At this time, the vertical beam 23 is inclined at a predetermined angle (an angle at which sunlight can be received most efficiently) θ1, and the subunit 10 lifted by the forklift 100 is slightly inclined by the forklift 100. Although it can be held, the inclination angle θ2 is extremely smaller than the inclination angle θ1 of the vertical beam 23.

  Next, as shown in FIG. 11B, in this holding state, the front and rear two places that are approached from the front side of the gantry 20 and are attached to the upper inclined side of the mounting inclined surfaces 23 a and 23 a of the adjacent vertical bars 23 and 23. The installation ends 12e and 12e on both sides of the two front and rear support rails 12 and 12 fixed to the subunit 10 are opposed to the receiving portions 25 and 25 (total of four locations).

  At this time, as described above, since the inclination angle θ1 of the vertical beam 23 and the inclination angle θ2 of the subunit 10 are different, first, as shown in FIG. The support rail 12 on the inclined upper side (the right support rail 12 in FIG. 11C) approaches the upper plate 25b of the receiving portion 25 on the inclined upper side of the mounting inclined surface 23a (the receiving portion 25 on the right side in FIG. 11C) or Make contact.

  At this time, as described in the above-described prior art, for the driver of the forklift 100, the vertical rails 23 and 23 are hidden by the subunit 10, and slightly from the edge of the mounting inclined surface 23a of the vertical rail 23 in the lateral direction. The end portion of the receiving portion 25 that protrudes to the end of the sub-unit 10 is hardly visible, and the installation end portion 12e of the support rail 12 slightly protruding from both ends of the subunit 10 is also hardly visible.

  Therefore, the driver of the forklift 100 holds the vertical rail in a state where the height position of the support rail 12 on the inclined upstream side is previously held at a slightly higher position than the height position of the receiving portion 25 on the inclined upstream side of the vertical rail 23. By slowly approaching 23, the installation end portion 12 e of the support rail 12 is made to approach or contact the upper side plate 25 b of the receiving portion 25. When the installation end portion 12e of the support rail 12 abuts, a slight reaction is transmitted to the subunit 10 side (or by listening to a slight contact noise), the driver can make a reaction or By confirming the contact sound, it is possible to recognize that the installation end portion 12e of the support rail 12 is at a predetermined position of the receiving portion 25.

  At this time, even if the back glass 11c of the subunit 10 hits the upper edge 25b1 of the upper side plate 25b of the receiving portion 25, the receiving portion 25 (that is, the upper side plate 25b of the configuration example 3 shown in FIGS. 10C to 10E). Since the back glass 11c can be prevented from coming into direct contact with the upper edge 25b1 by using the receiving part 25) having the configuration in which the elastic member 27 is attached to the upper edge 25b1, the breakage of the back glass 11c is ensured. Can be prevented.

  Then, by lowering the entire subunit 10 in this state, as shown in FIGS. 11C to 11D, the installation end 12 e of the support rail 12 on the upper side of the inclination is moved to the upper side plate 25 b of the receiving part 25 on the upper side of the inclination. The subunit 10 is rotated in the descending direction with the contacting portion Q (see FIG. 12) as a fulcrum. At this time, as shown in FIG. 12, in the descending process, the support rail 12 on the upper side of the slope slides on the upper plate 25 b and slides onto the installation plate 25 a and is fitted into the receiving portion 25.

  As a result, as shown in FIG. 13, the support rail 12 on the inclined lower side fixed to the back surface of the subunit 10 is also lowered toward the receiving portion 25 attached to the inclined lower side of the mounting inclined surface 23 a, Finally, it is mounted on the installation plate 25a.

  As described above, the upper-side subunit 10 is installed on the vertical beam 23 of the gantry 20.

  Thereafter, the forklift 100 is further lowered (see FIG. 11E), and then the forklift 100 is retracted (see FIG. 11F), so that the forklift 100 is clawed from under the subunit 10 placed on the upper stage side of the gantry 20. Is extracted. As described above, since the upper-side subunit 10 is installed, the next subunit 10 is then lifted by the forklift 100, and the lower-side subunit 10 is moved to the lower-stage side of the vertical rail 23 of the gantry 20 in the same manner as described above. Install in.

  Furthermore, in the present embodiment, since (n + 1) gantry 20 are arranged in the horizontal direction, a number of subunits 10 can be moved up and down by performing the same processing as described above while sequentially moving in the horizontal direction. In a two-stage state, n pieces are continuously placed in the horizontal direction.

  Thereafter, the installation end portion 12e of the subunit 10 placed on the receiving portion 25 is fixed to the receiving portion 25 of the vertical beam 23 using a fixture 24 described later.

  According to the installation method of the present invention, the installation end 12e can be received simply by bringing the installation end 12e of the support rail 12 of the subunit 10 into contact with the upper side plate 25b of the reception unit 25 attached to the vertical rail 23. Since the positioning for fitting on the installation plate 25a of the portion 25 can be performed, the operation of installing the subunit 10 on the gantry 20 can be performed smoothly.

<Description of structure for fixing subunit 10 to mount 20>
Finally, a structure for fixing the subunit 10 installed on the gantry 20 as described above to the gantry 20 using the fixture 24 will be described. That is, a joining structure for joining the installation end portions 12e and 12e of the support rails 12 and 12 of the subunits 10 and 10 adjacent in the left and right direction X to the receiving portion 25 attached to the vertical rail 23 of the gantry 20 is shown in FIG. This will be described below with reference to FIG.

  FIG. 14 is a schematic perspective view of a state in which the receiving portion 25 is attached and fixed to the vertical rail 23 as viewed obliquely from above. Note that a plurality of (four in this case) receiving portions 25 are provided in one vertical cross 23, and the mounting configuration of the vertical cross 23 and the receiving portion 25 is substantially the same. Therefore, in FIG. 14 and FIGS. 15 to 18 to be described later, a single vertical rail 23 and a receiving portion 25 are shown as a representative configuration.

  FIG. 15 is a schematic perspective view of a state in which the receiving portion 25 is attached and fixed to the vertical rail 23 as viewed obliquely from below. 16 is a schematic cross-sectional view taken along the line H1-H1 in FIGS. 14 and 15 showing a state in which the receiving portion 25 is attached and fixed to the vertical rail 23. FIG. FIG. 17 shows a state in which the installation end portions 12e and 12e of the support rails 12 and 12 adjacent to each other in the left and right direction X face each other and are fixed by the fixture 24 with respect to the receiving portion 25 fixed to the vertical beam 23. It is the general | schematic disassembled perspective view seen from the top. 18 shows a state in which the installation end portions 12e and 12e of the support rails 12 and 12 adjacent to each other in the left and right direction X face each other with respect to the receiving portion 25 fixed to the vertical beam 23 and are fixed by the fixture 24. It is a schematic sectional drawing in alignment with the H2-H2 line | wire of FIG.14 and FIG.15 which shows this.

  As shown in FIGS. 14 to 18, a through hole 23c through which the male screw S1 passes is provided at a position where the receiving portion 25 of the upper side plate 23b constituting the mounting inclined surface 23a of the vertical rail 23 is provided.

  As described above, the receiving portion 25 includes the installation plate 25a, the upper side plate 25b, and the lower side plate 25c. The installation plate 25a is provided with a female screw hole 25e for screwing the screw portion S1a of the male screw S1. The through hole 23c of the vertical beam 23 is larger than the size of the female screw hole 25e of the receiving portion 25 screwed with the male screw S1, and smaller than the size of the head S1b of the male screw S1. According to this configuration, the receiving portion 25 is disposed on the mounting inclined surface 23a of the upper side plate 23b of the vertical rail 23, and the male screw S1 passes through the through hole 23c from the lower side of the side plate 23b to receive the receiving portion 25. By being screwed into the female screw hole 25e, it is securely fixed to the side plate 23b on the upper side of the vertical beam 23.

  More specifically, the bottom surface 25a1 (see FIGS. 15, 16, and 18) of the installation plate 25a allows the movement of the receiving portion 25 in the inclined direction W while restricting the movement of the receiving portion 25 in the left-right direction X. A regulating rib 25d (see FIGS. 15, 16, and 18) is provided. The restricting ribs 25d are provided in the left-right direction X at an interval approximately equal to the width in the left-right direction X of the upper side plate 23b of the vertical rail 23. The female screw hole 25e is located between the regulating ribs 25d to 25d provided at intervals in the left-right direction X. According to this configuration, the receiving portion 25 is disposed on the upper side plate 23b of the vertical rail 23 and is restricted from moving in the left-right direction X by the restriction ribs 25d to 25d, and the male screw S1 is located below the side plate 23d. And through the through hole 23c of the side plate 23d and screwed into the female screw hole 25e of the receiving portion 25, the upper side plate 23b of the vertical rail 23 (more precisely, on the mounting inclined surface 23a of the side plate 23b) Fixed to. Specifically, the regulation ribs 25d to 25d are also provided at intervals in the tilt direction W. Here, the restriction ribs 25d to 25d are provided in a total of four places, two places in the left-right direction X and two places in the inclined direction W. The female screw hole 25e is located at the center of the intersection of diagonal lines passing through the four regulating ribs 25d to 25d. By doing so, it is possible to easily align the through hole 23c in the side plate 23b on the upper side plate 23b of the vertical rail 23 and the female screw hole 25e in the installation plate 25a of the receiving portion 25, thereby improving the mounting workability. It becomes possible.

  As shown in FIGS. 17 and 18, the fixture 24 includes a bottom plate 24a, inclined plates 24b and 24b that are bent obliquely upward and outward at two opposite sides of the bottom plate 24a in the inclined direction W, and each inclined plate 24b, Each side plate 24d, 24d is bent downward at the upper sides 24c, 24c of 24b. The fixture 24 having such a configuration can be formed by punching and bending a steel plate and plating the surface thereof. In the present embodiment, the lower ends 24e of the side plates 24d, 24d are formed in a number of triangular mountain shapes (triangular teeth) along the left-right direction X. By doing so, the installation end portions 12e and 12e of the support rails 12 and 12 can be securely held and fixed to the receiving portion 25.

  Further, the bottom plate 24a of the fixture 24 is provided with a through hole 24f through which the screw portion S1a of the male screw S1 passes. Further, two female screw holes 24g and 24g respectively screwed into the two male screws S2 and S2 at the symmetrical positions on both sides in the left-right direction X through the through holes 24f in the bottom plate 24a of the fixture 24 (see FIG. 17). Is provided.

  On the other hand, the receiving portion 25 has two through holes 25h and 25h through which the screw portions S2a and S2a of the two male screws S2 and S2 respectively screwed into the two female screw holes 24g and 24g provided in the fixture 24 are passed. (See FIG. 17) are provided at symmetrical positions on both sides in the left-right direction X via the female screw holes 25e. The two through holes 25h and 25h are larger than the sizes of the two female screw holes 24g and 24g, respectively, and smaller than the sizes of the heads S2b and S2b of the two male screws S2 and S2. According to this configuration, the fixture 24 is placed on the installation end portions 12e and 12e of the support rails 12 and 12 adjacent to each other in the left-right direction X, which is placed on the installation plate 25a of the receiving portion 25 and is abutted against each other. In this state, the two male screws S2 and S2 pass through the two through holes 25h and 25h of the receiving portion 25 and are screwed into the two female screw holes 24g and 24g of the fixture 24, thereby fixing the receiving portion 25 to the receiving portion 25. The installed end portions 12e and 12e of the support rails 12 and 12 adjacent to each other in the left-right direction X can be reliably fixed to the receiving portion 25 by the fixing tool 24 thus made.

  More specifically, the two female screw holes 24g and 24g have virtual centers passing through the center β parallel to the left-right direction X on both sides of the left-right direction X with the center between the centers β (see FIG. 17) of the through-hole 24f. It is located on a straight line γ (see FIG. 17). The distance between one female screw hole 24g and the center β of the through hole 24f and the distance between the other female screw hole 24g and the center β of the through hole 24f are the same distance.

  In this Embodiment, the some solar cell module main body 11 is connected in parallel, and the support rails 12 and 12 are adhere | attached through the adhesive agents 30-30 on the back surface of the some solar cell module main body 11-11. ing. This makes it possible to increase the size of the subunit 10 with a simple configuration.

  And in installing the subunits 10 to 10, the adjacent subunits 10 and 10 are arranged so as to be adjacent to each other with almost no gap between the installation plate 25a of the receiving portion 25 and the solar cell module main bodies 11 to 11. An operation for fixing the installation end portions 12e and 12e of the support rails 12 to 12 to the gantry 20 by the fixture 24 can be performed through a gap provided between the back surface and the back surface. Thereby, the subunits 10 and 10 can be reliably fixed in a state where the adjacent subunits 10 and 10 are arranged so as to be adjacent to each other with almost no gap. Therefore, it is possible to increase the power generation efficiency while reducing the space between the adjacent subunits 10 and 10. In addition, on the back side of each of the subunits 10 and 10, the strength of the fixture 24 and the gantry 20 can be maintained without particularly restricting the size of the fixture 24 and the gantry 20, and thereby The stable support structure and support strength of the units 10 to 10 can be ensured.
