The lower fixing bracket 10 is fixed to the slope 200 (the portion with the rafter) by wood screws 81 and 82 which are fixing means inserted into through holes 11a and 11b formed in the base 11. The fixing means for fixing the lower fixing bracket 10 to the inclined surface 200 is not limited to the wood screws 81 and 82 but may be other means (for example, an adhesive).

  The upper fixing bracket 20 has a substantially L-shaped cross section, and includes a leg portion 21 that extends in parallel with the slope 200 and a trunk portion 22 that rises upward from below the slope of the leg portion 21. In the leg portion 21, a fastened portion 25 to be fastened to the fastening portion 14 is formed on the upper side of the slope, and a trunk portion 22 is erected on the lower side of the slope. The trunk portion 22 extends upward in a space between the lower solar cell module 100A and the upper (ridge side) solar cell module 100B.

  The head portion 23 at the top of the body portion 22 has a downward engagement portion 23a that engages with the flange 8Cb of the lower solar cell module 100A and an upward engagement portion 23b that engages with the flange 8Ab of the upper solar cell module 100B. Is formed. An upper module mounting portion 24 is provided which is provided on the wall surface on the upper side of the slope of the middle portion of the trunk portion 22 and mounts the lower surface of the upper solar cell module 100B.

  The fastened portion 25 and the fastened portion 14 include a through hole 25 a (FIG. 7) formed in the fastened portion 25 and a through hole 14 a formed in the fastened portion 14 in the nut 84 disposed on the back surface of the fastened portion 14. A bolt 83 passing through (FIG. 6) is screwed and fastened. A detent 14 b is erected so as to come into contact with the nut 84 from the base 11, and the workability of fastening of the fastened part 25 and the fastening part 14 is improved.

  The upper fixing metal fitting 20 and the lower fixing metal fitting 10 fasten the fastened portion 25 and the fastening portion 14, thereby lowering the lower solar cell module between the downward engaging portion 23 a and the lower module mounting portion 12. Hold 100A tightly. That is, the upper fixing bracket 20 and the lower fixing bracket 10 sandwich the upper edge portion of the lower solar cell module 100A. Thereby, the upper edge portion of the lower solar cell module 100A is firmly fixed in the X, Y, and Z3 directions.

  On the other hand, the upper fixing fitting 20 loosely fits the lower edge portion of the upper solar cell module 100B between the upward engagement portion 23b and the upper module placement portion 24. In other words, it fits with some play. Actually, as shown by a dotted line in FIG. 8, the upper solar cell module 100B is approached from diagonally upward, and the flange 8Ab is engaged with the upward engagement portion 23b provided at the upper portion, and this engagement is made. Using the position as a fulcrum, the lower end of the frame 8A is placed on the upper module placement portion 24 by rotating as indicated by the white arrow in FIG. In order to perform laying in such connection work, the lower edge portion of the upper solar cell module 100B fits loosely between the upward engagement portion 23b and the upper module placement portion 24, and movement in the X and Z2 directions is not performed. Although it is almost regulated, the movement in the Y direction is regulated to the extent of friction.

  Here, when the lower solar cell module 100 </ b> A and the upper solar cell module 100 </ b> B are fixed, the relationship between the support portions and the solar cell module frame height is as follows: the downward engaging portion 23 a and the lower module mounting portion 12. , H1 is the height between the upper engaging portion 23b and the upper module mounting portion 24, and H0 is the height of the frame of the solar cell module, the symmetry relationship is H1 < The relationship is H0 <H2. That is, the solar cell module is firmly fixed at the upper side edge and is loosely supported at the lower side edge.

Returning to FIG. 1, the procedure for attaching the solar cell module is performed as follows.
(A) The lower fixing bracket 10 of all stages is fixed to the slope 200 with wood screws 81 and 82.
(A) The upper fixing bracket 20 is fastened to the lower fixing bracket 10 on the most eaves side with a bolt 83.
(C) The lower edge portion of the solar cell module 100A is fitted with the upper fixing bracket 20 and attached. (Do not use screws or other fastening structures).
(D) After assembling the upper fixing bracket 20 at the upper edge of the solar cell module 100A, the upper fixing bracket 20 is fastened to the lower fixing bracket 10 with bolts 83, so that the solar cell module 100A is attached to the inclined surface 200. Fix it.
(E) The lower edge portion of the solar cell module 100B is fitted to the upper fixing fitting 20 and attached.

  According to the fixing bracket of the solar cell module having such a configuration, the bolt for fastening the upper fixing bracket and the lower fixing bracket is in a position overlapping the upper solar cell module in a direction perpendicular to the inclined surface. And the bolt for fastening does not exist between a lower side solar cell module and an upper side solar cell module. Therefore, the space | interval between a lower side solar cell module and an upper side solar cell module can be narrowed.

  Further, the upper edge portion of the solar cell module is strongly sandwiched between the downward engaging portion 23a and the lower module mounting portion 12 by the fastening force for fastening the fastened portion 25 and the fastening portion 14, and the solar cell. Since the lower edge of the module does not require a fastening means, it has a structure in which the upper module placement portion 24 is loosely fitted between the upper engagement portion 23b and the upper module placement portion 24. Although the bolts for fastening the upper fixing bracket and the lower fixing bracket are positioned so as to overlap the upper solar cell module, the solar cell module can be easily and reliably laid.

  Further, since the lower fixing bracket and the upper fixing bracket are separable, the solar cell module can be easily removed simply by loosening the bracket connecting portion (bolt) during maintenance. That is, it is not necessary to remove the lower fixing bracket from the installation structure such as a roof. In order to remove the lower fixing bracket from the roof, it is necessary to remove the rafters of the roof or the wood screws that are struck on the base plate portion, which may cause insufficient strength and rain leakage when reattaching.

  Furthermore, the lower edge of all the solar cell modules are tightened with bolts so that the frame of the solar cell module is sandwiched between the lower fixing bracket and the upper fixing bracket. Fixing becomes strong. On the other hand, since the frame of the upper fixing fitting is fitted and installed on the upper edge of the solar cell module, there is no screw tightening work and the workability is good.

FIG. 10 is a cross-sectional view of only the lower fixing bracket of the fixing bracket of the second embodiment. FIG. 11 is a cross-sectional view of only the upper fixture of the fixture of the second embodiment. In the upper fixing bracket 20B of the present embodiment, the downward engaging portion 23a and the upward engaging portion 23b formed on the head 23 are formed so as to overlap in a direction perpendicular to the inclined surface 200, and are different. It is at a height. That is, as shown in FIGS. 9 and 10, the head portion 23 has an approximately S-shaped cross section, and the upward relationship that engages the flange 8Ab of the upper solar cell module 100B with the curved portion at the top of the S-shape. A joining portion 23b is formed, and a downward engaging portion 23a that engages with the flange 8Cb of the lower solar cell module 100A is formed in the central curved portion of the S-shape. Utility spaces (in FIG. 9) S1 and S2 for arranging cables and connectors are formed between the downward engaging portion 23a and the leg portion 21 and between the upper module mounting portion 24 and the leg portion 21. ing. Other configurations are the same as those of the first embodiment.

  FIG. 12 is a perspective view showing a state in which solar cell modules are laid in stages using the fixing bracket according to the present invention. In the present embodiment, since the fixing bracket has the structure as described above, the upper solar cell module 100B forms a step that is one step higher at the fixing position by the fixing bracket. FIG. 12 also shows the state of the eaves-side tips of the solar cell modules that form a row. The side facing the eaves of the solar cell module 100A at the eaves side tip is covered with an eaves end cover 85 over the entire length.

  In the fixing bracket of the present embodiment, the upper solar cell module is raised by one step at the portion where the solar cell modules provided in the inclined direction are connected. When more solar cell modules are connected, they are installed in a staircase shape (stepped shape), and the eaves side solar cell panel and the eave side frame of the eaves side solar cell panel are identical. Due to the overlapping structure, the solar cell panel installation area on the roof can be further reduced (the number of solar cell panels that can be installed on the roof can be further increased).

  Further, utility spaces (S1 and S2) are formed between the downward engaging portion 23a and the leg portion 21 and between the upper module mounting portion 24 and the leg portion 21, and a cable is connected to this space. By wiring the cable, it is possible to prevent contact (rubbing) between the cable and the roofing material over time and to prevent deterioration of the cable. In addition, by disposing the connector in this space, even if there is a fire between the connectors, the connector portion is surrounded by the metal fixing bracket, so that it is possible to prevent the spread of fire.

  Furthermore, in the present embodiment, the angle of the light receiving surface of the solar cell module can be arbitrarily changed by adjusting the heights of the upward engaging portion 23b and the upper module placement portion 24. By changing the light receiving surface to an optimum angle, the actual amount of solar radiation can be increased, which contributes to an improvement in the amount of power generation.

  FIG. 13: is a side view which makes a cross section a part which shows the other example of Embodiment 2 of the fixing metal fitting concerning this invention. In the upper fixing metal fitting shown in FIG. 13, the leg portion 21 and the upper module mounting portion 24 are coupled by the connecting portion 28 at the tip, and the inside has a hollow structure, so that the rigidity is enhanced. In order to perform the screw fastening operation of the bolt 83, the connecting portion 28 is formed with a through hole 28a. In this example, since the distance (D in FIG. 13) between the bolt tightening position by the bolt 83 and the downward engagement portion 23a (module tightening position) is small, the tightening force of the lower solar cell module 100A is further increased. growing.
