Embodiment 1 of the Invention
Embodiment 1 of the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view conceptually showing the installation structure of the solar cell module according to the first embodiment.

  As shown in FIG. 1, a large number of roof tiles 110 and 111 are laid on a trapezoidal inclined roof 100. Here, the roof tile 110 is a normal roof tile, and the roof tile 111 is a roof tile for attaching the rail fixtures 120 and 130.

  The rail fixtures 120 and 130 are used to support and fix the rails 141 and 142. Here, the short rail 141 is supported and fixed by one rail fixture 120. On the other hand, the long rail 142 is supported and fixed by the two rail fixtures 130.

  A plurality of solar cells 150 are disposed on the rails 141 and 142. As shown in FIG. 1, in the first embodiment, a long side solar cell module 151 and a trapezoidal solar cell module 152 are combined to form a trapezoidal solar cell 150 as a whole.

  2 to 4 are views showing a rail fixing structure using the rail fixing tool 120. FIG. 2 is a perspective view, FIG. 3 is an exploded perspective view, and FIG. 4 is a cross-sectional view.

  As described above, the rail fixture 120 is fixed to the roof tile 111. As shown in FIGS. 2 to 4, the roof tile 111 includes a bolt through hole 111 a and four screw through holes 111 b.

  The rail fixture 120 includes a connecting material receiving bracket 121, a rail receiving connecting material 122, and two rail receiving portions 123. The two rail receiving portions 123 are arranged sufficiently apart from each other so that the rail 141 can be stably held. For this reason, the connecting material receiving bracket 121 also sets the length of the rail 141 in the longitudinal direction so that the two rail receiving portions 123 can be sufficiently separated from each other.

  The connecting material receiving bracket 121 has a convex bent shape, and the central portion 121a is higher than both end portions 121b. The central portion 121a can be appropriately inclined according to the set angle of the rail 141 (see FIG. 3). The central portion 121a is provided with an opening 121c for exposing the bolt through hole 111a of the roof tile 111 and a bolt through hole 121d. Moreover, the screw through-holes 121e are provided in the position corresponding to the screw through-hole 111b of the roof tile 111 in the both ends 121b, respectively. The connecting material receiving bracket 121 is fixed on the roof tile 111 by screwing screws 121f into the roof plate (not shown) via the screw through holes 121e and 111b.

  The rail receiving connecting member 122 has a concave bent shape and has a bottom surface 122a and a side surface 122b (see FIGS. 3 and 4). The bottom surface 122 a is provided with a bolt through hole 122 c corresponding to the bolt through hole 111 a of the roof tile 111, and a bolt through hole 122 d corresponding to the bolt through hole 121 d of the connecting material receiving bracket 121. The rail receiving connecting member 122 is fixed to the connecting member receiving bracket 121 using bolts 122e and nuts 122f, and is fixed to the roof tile 111 using bolts 122g and nuts 122h.

  Two rail receiving portions 123 are attached to the rail receiving connecting member 122 along the longitudinal direction of the rail 141 (see FIGS. 2 and 3). The rail receiving portion 123 includes a pair of leg portions 123a that come into contact with the side surface 122b of the rail receiving connecting member 122 from the outside. The leg portion 123a is fixed to the side surface 122b of the rail receiving joint member 122 using a bolt 122i and a nut 122j.

  Furthermore, the rail receiving portion 123 includes a support portion 123b (see FIGS. 3 and 4). The support portion 123b supports and fixes the rail 141 by pressing both side surfaces of the rail 141 from the outside with two bolts 123c. For this reason, the support part 123b is provided with the nut accommodating part 123d and the auxiliary | assistant material 123e so as to oppose the both sides | surfaces of the rail 141, respectively (refer FIG. 4). The nut accommodating portion 123d is formed integrally with the leg portion 123a, and accommodates the nut 123e in a non-rotatable manner. The auxiliary material 123e is formed to be substantially similar to the nut housing portion 123d, and is fitted into the nut housing portion 123d from the outside. The bolt 123c passes through a bolt through hole (not shown) provided in the nut housing portion 123d and the auxiliary member 123e and is screwed into the nut 123e.

  When the rail 141 is fitted into the rail receiving portion 123, the upper end portion of the nut accommodating portion 123d is fitted into the inverted L-shaped convex portion 141a of the rail 141 (see FIG. 4). Thereafter, when the bolt 123c is rotated, the auxiliary member 123e is fitted into the nut housing portion 123d and the inverted L-shaped convex portion 141a. When the bolt 123c is further rotated, the tip of the bolt 123c presses the side surface of the rail 141 from both sides, and the rail 141 is fixed to the rail receiving portion 123. With this configuration, the rail receiving portion 123 can hold the rail 141 at an arbitrary position in the longitudinal direction, and therefore, the position adjustment of the rail 141 is easy.

  FIG. 5 is a perspective view showing a rail fixing structure using the rail fixture 130. As described above, the rail fixture 130 is used when the long rail 142 is supported and fixed at two locations (that is, two rail fixtures) (see FIG. 1).

  Similar to the rail fixture 120, the rail fixture 130 is fixed to the roof tile 111. That is, in the first embodiment, the same roof tile 111 can be used to attach the rail fixtures 120 and 130.
