Description

  The present invention relates to a solar cell module mounting structure on, for example, an inclined roof.

  2. Description of the Related Art Conventionally, as a structure for attaching a solar cell module to a roof, an attachment structure for fixing a solar cell module in order from an eave side to a ridge side on a sloped roof base plate or a frame laid on the roof is known. For example, after fixing a suspension made of a metal plate to a ground plate of an inclined roof with a screw or the like, hook the integrated steel plate tile to which the solar cell module body is attached to the suspension, and the upper end of the integrated steel plate tile (ridge side) Attach another hanging element to the side of the ridge with a high slope, fix the hanging element with a screw or the like, and attach the integrated steel roof tile on the eaves side. Next, hook the lower end of the next integrated steel plate tile on the hanging element, hook another hanging element on the upper end of the integrated steel sheet tile and pull it toward the ridge, and fix the hanging element with a screw or the like, Install the steel plate roof tile on the building side. Hereinafter, by repeating such construction, there is known a method of sequentially attaching integrated steel plate tiles from the eave side to the ridge side of an inclined roof (for example, see Patent Document 1).

  The mounting structure described in Patent Document 1 is a structure in which an integrated steel plate tile in which a frame that uses a frame to hold a solar cell module body is attached to a tile material is attached in order from the eave side to the ridge side of the inclined roof. The solar cell module with the integrated frame can be attached in order from the eave side to the ridge side of the inclined roof in the same manner as described above.

  In addition, in the structure in which the solar cell modules are attached in order from the eave side to the ridge side, on the landscape, the eave side tip of the eave side solar cell module or the gap between the eave side solar cell module and the ridge side solar cell module It is necessary to devise such as covering with a cover.

  Conventionally, a support fitting integrally provided with a positioning piece of a solar cell and a decorative cover mounting piece is fixed to the tip of a mount for mounting the solar cell module, and the eaves side end of the solar cell module is brought into contact with the positioning piece, There is known a solar cell module support device in which a screw inserted from the outside of a cover is screwed into a screw hole of a decorative cover mounting piece so that the front end of the gantry and the end of the solar cell module are covered with the decorative cover (for example, , See Patent Document 2).

  Further, as a structure in which the gap between the eave-side solar cell module and the ridge-side solar cell module is covered with a closing cover, the fixing portion of the fixing member fixed to the closing cover is mounted on the roof material together with the fixing bracket of the solar cell module. An arrangement is known which is fixed to the roof side with a fixing tool such as a nail (see, for example, Patent Document 3).
