In another solar cell panel construction method, in the next step S22, the low support metal fittings 23 and the high support metal fittings 24 that support only one long side of the metal frame 102 of the solar cell panel 10 are temporarily placed on the foundation 21. To.

Then, in the next step S23, first, the remaining low support metal fittings 23 and high support metal fittings 24 are temporarily assembled to the solar cell panel 10 by inserting the protrusions 233b and 243b into the support holes 102a. Will be done. Subsequently, these low support metal fittings 23 and high support metal fittings 24 are installed together with the solar cell panel 10.

FIG. 19 is a schematic view showing how a set of low support metal fittings and high support metal fittings are installed together with a solar cell panel in step S23 of the support metal fitting installation process shown in FIG. In FIG. 19, the installation of one solar cell panel 10 is shown by taking the high support metal fitting 24 as an example.

The installation of the solar cell panel 10 here is performed while the operator manually supports the temporarily assembled low support metal fittings 23 and high support metal fittings 24. First, the protrusion 243b of the high support metal fitting 24 and the protrusion 233b of the low support metal fitting 23 temporarily placed on the placement foundation 21 are inserted into the two support holes 102a of the solar cell panel 10 that are not subject to temporary assembly. .. Subsequently, the low support metal fittings 23 and the high support metal fittings 24 are lowered together with the solar cell panel 10 in the direction of arrow D16 with these protrusions 233b and 243b as rotation centers. As a result, the anchor bolts 211 of the placement foundation 21 are inserted into the through holes 231a (see FIG. 5) of the low support metal fittings 23 and the through holes 241a (see FIG. 6) of the high support metal fittings 24. At this stage, neither the low support metal fitting 23 nor the high support metal fitting 24 is fixed to the anchor bolt 211 yet. Therefore, when the low support metal fitting 23 and the high support metal fitting 24 are lowered together with the solar cell panel 10, the low support metal fitting 23 and the high support metal fitting 24 move to a position that naturally fits in. As a result, in the support metal fitting installation step in this alternative solar cell panel construction method, the relative positions of the protrusions 233b and 243b of the low support metal fitting 23 and the high support metal fitting 24 with respect to the four support holes 102a in the metal frame 102, respectively. Matching is done. After that, each of the low support metal fitting 23 and the high support metal fitting 24 is fixed to the foundation 21 by fastening the nut 213 to the anchor bolt 211.

Then, following the support metal fitting installation steps from step S21 to step S23 described above, the metal frame 102 of the already installed solar cell panel 10 is sandwiched between the low support metal fitting 23 and the high support metal fitting 24. The presser foot fitting installation process is performed. In this presser fitting installation step, the boundary presser fitting 25 described with reference to FIG. 9 and the end presser fitting 26 described with reference to FIG. 10 are installed. The above processing is performed for all the rows of the solar cell panel 10 shown in FIG. 1, and this alternative solar cell panel construction method is completed.

Needless to say, the solar cell panel 10 can be easily installed by the solar cell panel construction method of another example described above while suppressing the construction cost as in the solar cell panel construction method of the above-described embodiment.

Further, in another example of the solar cell panel construction method, in the support metal fitting installation process, the solar cell panel 10 is installed and each protrusion 233b, by temporarily assembling the low support metal fitting 23 and the high support metal fitting 24 to the solar cell panel 10. Alignment of 243b is performed together. Therefore, since the solar cell panel 10 is installed more efficiently, the construction cost can be further suppressed and the solar cell panel 10 can be easily installed.

Here, in any of the solar cell panel construction method of the embodiment described with reference to FIGS. 11 to 14, and the solar cell panel construction method of another example described with reference to FIGS. 18 and 19. The height of the low support metal fitting 23 and the high support metal fitting 24 can be adjusted as follows.

In the center thereof, a through hole 271 through which a bolt 254 for fixing the boundary holding metal fitting 25 and the end holding metal fitting 26 passes is provided. Further, in the vicinity of each short side, a notch 272 through which the protrusion 233b of the low support metal fitting 23 and the protrusion 243b of the high support metal fitting 24 pass is formed. As a result, the spacer 27 avoids the protrusions 233b and 243b, and does not interfere with the attachment of the bolt 254, and the support plate portion 233 of the low support bracket 23 and the high support bracket 24 shown in FIG. It is possible to place it on the support plate portion 243 of.

In the example of FIG. 20, there is a difference in the height of the high support metal fitting 24 due to a slight difference in the height of the upper surface between the plurality of placement foundations 21. In the example here, the high support metal fitting 24 on the right side in the figure is the highest, followed by the high support metal fitting 24 on the left side in the figure and the high support metal fitting 24 in the center, in that order. If the solar cell panel 10 is installed as it is, the pair of high support metal fittings 24 will be tilted from each other. In order to avoid such an inclination, the spacer 27 is placed on the high support metal fitting 24 on the left side in the figure and the high support metal fitting 24 in the center, and the height is higher than that of the high support metal fitting 24 on the right side in the figure. Matching is being done. The number of spacers 27 to be mounted is larger in the central high support metal fitting 24.

As described above, in the present embodiment and the above-mentioned alternative example, the height of the low support metal fitting 23 and the high support metal fitting 24 can be adjusted by using the spacer 27 shown in FIG.

Higher than H1 (Fig. 5). Further, the slope of the support plate portion 909c from the upper end edge of the standing plate portion 909b is a downward slope unlike the low support metal fittings 23 of the first to fifth embodiments. The gradient of the support plate portion 909c is determined by whether the support hole 102a of the solar cell panel 10 is located on the higher side or the lower side of the inclination when viewed from the standing plate portion 909b. In the example here, since the support hole 102a is located on the lower side of the standing plate portion 909b, the slope of the support plate portion 909c is a downward slope. Which side of the support plate portion 909b the support hole 102a is located is determined by the pitch of the support hole 102a in the solar cell panel 10, and therefore, depending on this pitch, the gradient of the support plate portion 909c is different from that of the present embodiment. It can be an uphill slope.

The high support metal fitting 910 has substantially the same shape as the above low support metal fitting 909 except for the height H903, and includes a mounting plate portion 910a, a standing plate portion 910b, and a support plate portion 910c. It is a sheet metal member formed in a substantially Z shape in a side view.

It will be located in the space between the 910a and the solar cell panel 10. When the low support metal fittings 909 and the high support metal fittings 910 are fixed at a higher position than the ground A901, the length of the portion penetrating the mounting plate portions 909a and 910a is short. On the other hand, when the low support metal fittings 909 and the high support metal fittings 910 are fixed at a lower position from the ground A901, the lengths of the portions penetrating the mounting plate portions 909a and 910a become long. In the present embodiment, even if the low support metal fitting 909 and the high support metal fitting 910 are fixed at the lowest possible positions, the low support metal fitting 909 has a low support metal fitting 909 so that the tip 904b of the vertical bolt 904 does not hit the solar cell panel 10. The height H901 and the height H903 of the high support metal fitting 910 are long.

Here, also in the third embodiment shown in FIGS. 24 and 25 and the fourth embodiment shown in FIGS. 26 to 28, the low support metal fittings 23 and the high support metal fittings 24 are installed lower. Occasionally, the amount of penetration of the anchor bolts 751 and 802 becomes large. However, in these embodiments, it is assumed that the installation location is a flat roof A701 with a relatively small height difference, and the penetration amount is not so large. In consideration of this point, the low support metal fitting 23 and the high support metal fitting 24 having the same shape as those of the first, second, and fifth embodiments are adopted. If the height difference of the flat roof A701 as the installation location is larger than expected and the penetration amount of the anchor bolts 751 and 802 is large and it is likely to hit the solar cell panel 10, the following structure is adopted. .. That is, in this case, by using the spacer 27 shown in FIGS. 20 and 21, the distance between the low support metal fitting 23 or the high support metal fitting 24 and the solar cell panel 10 is widened, and the anchor bolt is bolted. Contact with 751,802 is avoided.

On the other hand, in the sixth embodiment, since the lower end 904a of the erection bolt 904 is housed in the groove 903 of the long foundation 901, the erection bolt 904 itself has a constant height from the ground A901. There is no choice but to become. Therefore, in the present embodiment, the height H901 of the low support metal fitting 909 and the height H903 of the high support metal fitting 910 are increased to correspond to the length of the penetration amount of the erection bolt 904.

Needless to say, even with the sixth embodiment described above, the solar cell panel 10 can be easily installed while suppressing the construction cost, as in the first embodiment described above.

Further, according to the present embodiment, by adjusting the mounting height of each support metal fitting to the erection bolt 904, it is possible to absorb the height difference at each place on the ground A901 and install the solar panel 10 satisfactorily. ..
