Next, a procedure for installing the solar cell power generator 15 on the roof 11 using the jig 41 will be described.

First, the required number of mounts 21 of the module fixing devices 16 and 17 (in this embodiment, two
Two pedestals 21 and one pedestal 21) for the intermediate rail are prepared, they are arranged on the roof 11 in parallel with each other, and
Wood screw 19 screwed into roof 11 through opening 24b
Fix each using.

FIG. 3 shows how the gantry 21 is installed on the roof 11. The installation operation is performed using a jig 41. That is, first, the end rail mount 21 of one module fixing device 16 arranged on the eave side is positioned and fixed to the roof 11 with the wood screw 19. Thereafter, the plurality of intermediate rail mounts 21 of the module fixing device 17 and the plurality of end rail mounts 21 of the other module fixing device 16 disposed on the ridge side, for example, 3 Positioning is performed by the book jig 41. For details, refer to the existing end rail stand 21 on the eaves side.
The positioning grooves, for example, grooves 42 at one end of each jig 41 provided at intervals in the longitudinal direction of the jig 41 are fitted into the module supports 24 of the existing end rail base 21, respectively. Are arranged so as to intersect at right angles with the existing end rail stand 21. Next, in this state, the module support 2 is held while the intermediate rail base 21 intersects each jig 41 at a right angle.
The positioning grooves 43 at the intermediate positions in the longitudinal direction of the three jigs 41 are fitted into the three locations 4 respectively. As a result, the intermediate rail mount 21 is replaced with the existing end rail mount 21 on the eaves side.
Are positioned parallel to and at a predetermined arrangement interval E. Similarly, while the other end rail mount 21 arranged on the ridge side intersects at right angles with each jig 41, the positioning grooves 44 of the three jigs 41 are provided at three places of the module support 24. Are fitted respectively. As a result, the ridge-side end rail mount 21 becomes the intermediate rail mount 2
1 and are positioned at a predetermined arrangement interval E in parallel.

In the positioning state of the gantry 21 for the intermediate rail and the gantry 21 for the ridge end rail, the opposing groove edges 47 of the positioning grooves 42 to 44 of the jigs 41
Since each of the bases 21 is in contact with the outer surface of both side walls 24f of the module support 24, these mounts 21 are in the width direction, that is,
Each jig 41 is prevented from moving in the longitudinal direction. Therefore, the arrangement interval E between the pedestals 21 adjacent to each other in the direction of the eaves of the roof 11 can be determined as neither narrow nor wide.

Then, under such a positioning state, each of the pedestal 21 for the intermediate rail and the pedestal 21 for the ridge end rail is fixed to the roof 11 with the wood screw 19. For this reason, the work to be newly installed, that is, the work for installing these mounts 21 while holding them by hand so that the intermediate rail mount 21 and the ridge end rail mount 21 are not accidentally displaced and moved, is performed. Is eliminated, and the three gantry 21 can be easily installed on the roof 11 at a predetermined arrangement interval E. (First Step) Next, the solar cell module 18 is temporarily placed between the pedestals 21 adjacent to the roof 11 in the eaves direction. In this temporary placing operation, the pair of frames 63 of the solar cell module 18 are positioned on the ridge side, and these are placed on the adjacent pedestal 2.
It can be carried out by placing it on the module supporting portion of the first ceiling wall 24a. FIG. 6 shows a state immediately before the solar cell module 18 is to be arranged between the adjacent frames 21. (Second Step) Thereafter, the nut plate 28 is screwed into the connecting bolt 29 already passed through the holding member 27 in the eaves-side pedestal 21 corresponding to the installation position of the temporarily placed solar cell module 18. For example, two assembled connection units 23 are set.
These units 23 are inserted through the end surface openings of the gantry 21 with the spigot projections 27a of the holding members 27 fitted in the openings 24b of the gantry 21, and are slid to the tightening position using the openings 24b as guides. In the tightening position, the nut plate 28 is located between the ridges 24d of the gantry 21 so as to be prevented from rotating.
7 is confirmed to cover the bottom wall 36 of the frame 33, the connection bolt 29 is lightly tightened, and each connection unit 2
3 is temporarily fixed to the tightening position. (Third Step) Next, after confirming the position of the solar cell module 18 that has been temporarily placed, the connection bolts 29 of the two connection units 23 are fully tightened, and the solar cell module 18
Is fixed to the gantry 21. This fixing is performed by the pressing member 27 and the nut plate 28
Between the holding member 27 and the bottom wall 36 of the eaves-side frame 33.
Is realized by being pinched. (Fourth Step) Then, the solar cell module 18 disposed adjacent to the ridge side with respect to the solar cell module 18 is mounted on the intermediate rail mount 21 by the same procedure as the second step. And the ridge-side (end-side) rail mount 21, the two connecting units 23 are set on the intermediate rail mount 21 at the tightening position in the same procedure as in the third step, and then these are connected. The connection unit 23 is fully tightened in the same procedure as in the fourth step, and the eave-side frame 3 of the solar cell module 18 is mounted on the intermediate rail base 21.
At the same time, the eaves-side frame 33 of the solar cell module 18 is fixed. The installation of the solar cell modules 18 in a row in the eaves ridge direction is repeated until a plurality of rows (for example, two rows) are reached.

Thereafter, the gantry cover 22 having only one cover protruding edge 22a is attached to the eave-side and ridge-side gantry 21 for the end rail, respectively, and a pair of covers 22a is provided.
Is attached to the intermediate rail mount 21. These attaching operations are performed by using a gantry cover 22 prepared in advance according to the total width of the two rows of solar cell modules 18.
Are positioned so that both ends thereof are aligned with both ends of the two rows of solar cell modules 18, and these covers 22 are lightly tapped from above, so that the pair of hook claws 22
b is hooked on the claw receiving portion 27b of each connecting unit 23. Also, even if the position of the gantry cover 22 is slightly displaced in this operation, the cover 22 is gently tapped in the axial direction from the end face side to cause slippage at the claw engagement portion, and the cover 22 is properly positioned. It is possible to move. The state in which the gantry cover 22 is attached in this manner is shown by the already installed solar cell modules 18 in FIGS. (The above is the fifth step) Then, by repeating the first to fifth steps described above for the installation of the solar cell modules 18 in only the necessary columns, the solar cell power generation on the roof 11 as shown in FIG. Device 15 can be installed. The photovoltaic power generator 15 installed in this manner positions the arrangement intervals E between the pedestals 21 in a predetermined manner that is neither narrow nor wide, and reliably assembles the plurality of pedestals 21 at a predetermined arrangement interval E. Since the construction is performed using the above-described construction jig 41 which can be easily set and placed, the workability of the entire solar cell power generation device 15 can be improved, and a plurality of the solar cell power generators 15 can be installed on the gantry 21 installed with high accuracy. The installation accuracy of the module 18 can be improved by fixing the solar cell module 18 in the above. The description of the installation procedure has been omitted, but each solar cell module 18

When a solar cell power generation device is installed on a roof using the jigs 41 of the second to fourth embodiments, the arrangement between the adjacent pedestals 21 is the same as in the jig of the first embodiment. The interval E is neither narrow nor wide, and is positioned as determined, so that the plurality of pedestals 21 can be easily installed at a predetermined interval E. Therefore, by using these construction jigs 41, it is possible to improve the workability of construction of the entire solar cell power generation device on the roof 11, and to install a plurality of solar cell modules on the gantry 21 installed with high accuracy. The fixing accuracy of these modules can be improved by fixing.

FIGS. 10 and 11 show a fifth embodiment of the present invention. This embodiment is different from the first embodiment in the configuration of a construction jig 41, and other configurations are the same as those in the first embodiment including portions not shown in FIGS. 10 and 11.

Since the groove edges of the fittings 44 are fitted respectively, it is possible to more reliably control the rail-shaped pedestal 21 to be installed, which prevents it from moving in the width direction. In addition, by fitting the groove edges of the two pieces 45 and 46 separated in the longitudinal direction of the gantry 21 into the module supports 24, the jig 41 itself crosses the gantry 21 obliquely. Since the movement can be prevented, it is possible to suppress the predetermined arrangement interval E between the plurality of gantry 21 from being impaired. Therefore, a plurality of frames 2
1 can be reliably installed at a predetermined arrangement interval E with high accuracy, and the mounting accuracy of these modules can be improved by fixing a plurality of solar cell modules on the pedestal 21.
