Although not shown in the figure, the cross rail fixing tool 20k with the slide metal fitting 21 is fastened according to the marking line (see FIG. 3) engraved on the upper surface of the roof fixing metal fitting 10. At this time, the cross rail 15 is on the slide metal fitting 21.
After that, the cross rail fixing tool 20j on the eave side can be fastened to fix the cross rail 15.

In FIG. 6, the support and fixing structure on the eaves side of the lowermost stage is illustrated, and the lower corner portion of the edge portion of the module P is fitted to the right corner portion of the upper end portion 19 and the upper surface portion 19h of the cross rail 15. Can be made to.
A side cover 30 is fitted into the left corner portion, and the module fixing bracket 25 can be pressed from above together with the edge portion of the module P to fix the side cover 30.
The top eaves side is symmetrical with FIG. 6.

Here, the configuration of the side cover 30 will be described. The side cover 30 has a vertical surface along the module fixing bracket 25, and has a trapezoidal cross section including an upper surface, a lower surface, and a slope, and the side cover 30 has a trapezoidal cross section. It comprises a form having an extension portion 30e extending diagonally downward.
The upper surface and the lower surface each have protrusions 30t in the longitudinal direction, and these protrusions 30t are a groove portion 28m provided on the lower surface of the holding portion 28 of the module fixing bracket 25 and a groove portion 19m provided on the cross rail 15. Can be fitted.
As a result, the side cover 30 is appropriately fitted to the module fixing bracket 25 and the cross rail 15, and is positioned so as not to be displaced.

FIG. 7 is an exploded explanatory view showing the configuration of the middle portion of the support and fixing structure according to the above embodiment.
FIG. 8 is an assembly explanatory view showing the configuration of the middle stage portion of the support and fixing structure also according to the above embodiment.

In the configuration of the middle stage, the modules P are installed sequentially from the eaves side toward the upper stage, but the second and subsequent stages are the same, and the configuration of the uppermost stage on the ridge side is as described above, FIG. It has a symmetrical configuration.

In this middle stage portion, the cross rail fixing tool 20k in which the slide fitting 21 is incorporated is first fitted from the ridge side of the roof fixing metal fitting 10, and then the cross rail fixing tool 20j is fitted. That is, it is fitted in the opposite direction to the case of FIG.

After that, the upper module P can be placed, and both modules P and P can be fixed between the modules P and P located above and below in the flow direction by the module fixing bracket 25.
The module fixing bracket 25 has the nut member 27 at the lower end fitted in advance from the end thereof in the space under the groove portion of the cross rail 15.

Here, in the present invention, unlike the conventional support and fixing structure, when the position of the module P is displaced and a gap or the like is generated between the module P and the upright portion 19 of the cross rail 15, the bolt 7 is easily removed. The feature is that it can be loosened, adjusted, and easily fixed again.

FIG. 9 is an explanatory view illustrating a spacer used when fixing the roof fixing bracket according to the above embodiment on the slate roof.
As can be seen from these figures, two types of spacers are used.
That is, each of the spacers A and B is made of a plate-like one, and when the eaves side is formed thinner than the ridge side and these spacers A and B are arranged in the flow direction as shown in the A arrangement, Is such that both bottom surfaces are flush with each other.

Then, when the spacers A and B are arranged in reverse like the B arrangement, a step is formed on the bottom surface thereof, and this step can be adapted to the step of the slate roof.
That is, in the case of the A arrangement, it can be placed on the flat surface of the slate roof, and in the case of the B arrangement, it is placed on the stepped portion of the slate roof and the roof fixing bracket 10 is arranged flat. It will be possible to fix it.

Although the embodiments of the present invention have been described above, in the present invention, the embodiments can be variously redesigned as follows.
Although FIG. 1 illustrates an installation example of one minimum unit of the present invention, the minimum units can be installed in a plurality of rows in the horizontal direction and in a plurality of stages in the flow direction.

Similarly, the lower and upper tiers can be staggered by shifting the arrangement position to the side.
As described above, when a large number of rows are provided in the horizontal direction and a large number of stages are provided in the vertical direction, the horizontal rails may be continuously arranged in a single row in the horizontal direction, but they are arranged at intervals between the horizontal rails. You can also do it.
This is because, in the case of the present invention, the module can be placed and fixed on the cross rail. This can also contribute to resource saving.

It is also free to provide end face covers that cover both ends of the cross rail located at the bottom, both ends of the cross rail located at the middle, and both ends of the cross rail located at the top.
The length, width and height of the roof fixing bracket in the longitudinal direction can also be set as necessary.
The stopper portion can also adopt a structure other than cutting and raising. The point is that the fitted cross rail fixture does not come off downward.

The shape and size of the cross rail fixture can also be set according to the size of the roof fixing bracket.
The structure of the slide metal fittings can be freely changed in design, but in short, any structure may be used as long as it can be appropriately engaged with both sides of the groove portion provided in the longitudinal direction of the upper surface of the roof fixing metal fitting and can slide in the longitudinal direction.

The length, width, and height of the cross rail in the longitudinal direction can also be set as necessary. Actually, various types of cross rails of appropriate length can be manufactured, and one of them can be selected and used as needed.
The module fixing bracket that presses and fixes the module mounted on the cross rail is also usually fixed at two places on one cross rail, but the fixing position can be freely changed in design.
Similarly, the fixing position of the module fixing bracket for fixing the module mounted on the cross rail can be freely set as needed.

As described above, the present invention uses, for example, a roof fixing bracket having an appropriate length, a cross rail, a cross rail fixing tool for fixing the cross rail to the roof fixing bracket, and a module fixing bracket on a slate roof, and a solar cell. The module can be easily fixed by arranging it in a horizontal rail shape, and the horizontal rail fixing tool provides a support fixing structure, a support fixing method, and a horizontal rail of a solar cell module whose fixing position can be easily finely adjusted. It was possible to provide.
