  As described above, the roof 3 with the solar power generation device according to the present embodiment has the roof materials 32, 32, 32, and 320 that are in contact with the upper surface of each rafter 31 as shown in FIG. 3 and FIG. The solar power generation device 33 was fixed to the upper surface of each rafter 31 while the ends 321 a and 321 a were being held by the solar power generation device 33. Thereby, it is not necessary to interpose an attachment member between the solar power generation device 33 and each roof material 32, 320 like a conventional roof with a solar power generation device, and the solar power generation device 33 is connected to each roof material 32, The number of parts when fixing to 320 is reduced. Therefore, the roof 3 with the solar power generation device of the present embodiment can reduce the manufacturing cost. Moreover, the carport 1 of this Embodiment can hold down manufacturing cost compared with the carport provided with the roof with the conventional solar power generation device by having provided the roof 3 with a solar power generation device.

  Further, the solar power generation device 33 is fixed to the upper surface of each rafter 31 while pressing the end portions 321 a and 321 a of the roof materials 32, 32, 32, and 320 onto the upper surface of each rafter 31 using the ground brackets 36 and 37. I did it. Therefore, since the earth brackets 36 and 37 are used as an attachment member to the rafter 31 in addition to grounding, it is possible to suppress the number of parts required for manufacturing the solar power generation device 33 as compared with the case where a new attachment member is provided. it can. Therefore, the manufacturing cost of the roof 3 with a solar power generation device can be further suppressed.

  Further, the solar power generation device 33 includes covers (intermediate cover 39, end cover 40, and ridge cover 41) that cover the ground brackets 36 and 37. Thereby, the ground brackets 36 and 37 can prevent an external impact. Therefore, durability of the roof 3 with a solar power generation device can be improved.

  In this embodiment, as shown in FIG. 4, the vibration absorbing material 34 is interposed between the roof materials 32 and 320 and the plurality of beams 22. Thereby, when the roof materials 32 and 320 vibrate due to wind or the like, the vibration is absorbed by the vibration absorbing material 34, so that it is possible to suppress generation of unpleasant noise due to vibration.

  Moreover, in this Embodiment, as shown in FIG. 2, the parapet 50 is couple | bonded with the rear side of each rafter 31, and the eaves 51 is couple | bonded with the front side.

  As shown in FIG. 9, the eaves 51 is formed so as to receive rainwater W that has entered the roof materials 32 and 320 from the upper surface of the photovoltaic power generation device 33. If it demonstrates concretely, the eaves bowl 51 will be comprised by integrating the parapet 51b in the outer side of the eaves bowl main body 51a. A vertical rod 52 is connected to the lower right side of the eaves main body 51a. The rainwater collected in the eaves 51 is discharged by this vertical shaft 52. Therefore, the roof 3 with the solar power generation device of the present embodiment can reliably discharge the rainwater W that has entered the roof materials 32 and 320 by the eaves fence 51 and the vertical fence 52.

  Further, a gap S is provided between the front end of the solar power generation device 33 and the eaves 51. For this reason, it becomes easy to flow the rain water W of the upper surface of the solar power generation device 33 into the eaves 51, and can improve the drainage efficiency of rain water. In addition, in order to improve discharge | emission efficiency, it is preferable to incline the gradient of the roof 3 with a solar power generation device toward the eaves 51 side (front side).

  As mentioned above, although embodiment concerning this invention was illustrated, this embodiment does not limit the content of this invention. Various modifications can be made without departing from the scope of the claims of the present invention.

  For example, in the present embodiment, the roof materials 32, 32, 32, and 320 that are in contact with the upper surface of each rafter 31 are all pressed by the solar power generation device 33. However, as shown in FIG. When the roof materials 32 and 32 (or 32 and 320) are not pressed by the solar power generation device 33, the pressing member 61 is preferably used. The pressing member 61 is formed in a cover shape so as to cover the upper portion of the rafter 31 from the upper side of the roof materials 32, 32, and an insertion hole 61a for the bolt 10 is formed on the upper surface thereof.

  When pressing the roof materials 32, 32 with the pressing member 61, the head of the bolt 10 is disposed in the mounting groove 31 a of the rafter 31. Next, the bolts 10 are passed through the insertion holes 61 a of the pressing member 61, and the end portions 321 a and 321 a of the roof materials 32 and 32 are pressed against the upper surface of the corresponding rafter 31 by the pressing member 61. Finally, the washer 10 b and the nut 10 a are fitted to the bolt 10 to fix the pressing member 61 to the rafter 31. By using this pressing member 61, it is possible to obtain the same durability as that of the roof 3 with a solar power generation device of the present embodiment.

  Moreover, by forming the pressing member 61 in a cover shape that covers the top of the rafter 31 from the upper side of the roof materials 32, 32, it is possible to prevent the pressing member 61 from inadvertently moving at the time of mounting. Installation workability can be improved. Further, it is possible to prevent rainwater from entering the mounting groove 31 a of the rafter 31 by the pressing member 61. In addition, the shape of the pressing member 61 does not need to be limited to a cover shape, and should just be formed so that the solar power generation apparatus 33 may hold | suppress the roof materials 32 and 32 which are not pressed down.

  Moreover, although this Embodiment demonstrated the case where the roof 3 with a solar power generation device of this invention was applied to the carport 1, the sunlight of this invention was applied to small buildings, such as a storeroom, besides the carport 1. A roof with a power generation device may be applied.

  As described above, the manufacturing cost of the roof with a solar power generation device and the carport of the present invention can be reduced. Therefore, this invention can fully be utilized in the technical field of the roof with a solar power generation device.
