Description

  The present invention relates to a building material integrated module including a frame for laying a solar cell module main body on a roof on each side of the solar cell module main body.

  A conventional solar cell module includes a frame body on each side of the solar cell module body, and each frame body has a U-shaped cross section (or a substantially U-shaped cross section for sandwiching and holding the end portion of the solar cell module body). The holding part formed in the character shape is provided (for example, refer patent document 1).

  In the solar cell module having such a structure, the end of the solar cell module main body (laminated part or glass part) is inserted into the holding part of the frame, so that rainwater or the like passes through the gap of the holding part. There is a possibility of leaking to the back of the.

  Therefore, in the conventional solar cell module, waterproofness is enhanced by interposing a waterproof material such as hot butyl, silicon resin, gasket, foam, etc. between the holding portion and the end of the solar cell module body. It has a structure.

  In this case, the frame has the same structure even in the building material integrated module, but in the building material integrated module, since the module itself also serves as a roof tile, particularly high waterproof properties are required.

JP 2005-282053 A

  In the structure of the conventional solar cell module described above, waterproofness is enhanced by a technique in which a waterproof material is interposed in an insertion portion between the holding portion of the frame and the end portion of the solar cell module main body. In this case, for example, when a gap occurs in the silicon resin or a foam occurs over time, the rainwater wraps around the lower surface side of the solar cell module body through the insertion portion. There has been a problem that the waterproof property of the solar cell module itself cannot be secured due to falling.

  The present invention has been devised to solve such problems, and its purpose is to review the structure itself of inserting the end of the solar cell module body into the holding part of the frame body, and to eliminate the insertion part. An object of the present invention is to provide a building material integrated module in which the possibility of forming a gap is eliminated and the waterproofness of the solar cell module itself is improved.

  In order to solve the above problems, a building material integrated module of the present invention is a building material integrated module in which a frame is provided on at least a pair of sides facing a solar cell module body, and the solar cell module body is laid on a roof. The frame body located on the eave side includes a leg portion and a receiving portion for receiving the end portion of the solar cell module body from below, and the lower surface of the receiving portion and the end portion of the solar cell module body. Are bonded and fixed by an adhesive member.

  According to this configuration, rainwater or the like does not enter the lower surface side of the solar cell module body through the adhesive member.

  According to the building material-integrated module of the present invention, the frame body includes a contact piece that extends upward from the leg portion and contacts the end surface of the end portion of the solar cell module body. Also good.

  According to the building material-integrated module of the present invention, the frame body includes an abutting piece extending upward from the leg portion along an end surface of the end portion of the solar cell module body, and the abutting portion. It is good also as a structure provided with the upper pressing piece extended in the upper surface side of the said edge part of the said solar cell module main body from the extension front-end | tip part of a piece.

  Moreover, according to the building material integrated module of the present invention, a buffer member may be arranged between the upper pressing piece and the upper surface of the end portion of the solar cell module body.

  According to this configuration, the end portion of the solar cell module main body can be always pressed against the receiving portion side of the frame body by the buffer member, so that the adhesive force of the adhesive member can be assisted.

  Moreover, according to the building material integrated module of the present invention, the frame body may be arranged on a side facing the side of the solar cell module body located on the eaves side.

  According to this structure, the insertion part can be eliminated in the side located on the eave side of the solar cell module body and the side located on the ridge side.

  According to the present invention, since the receiving portion of the frame body located on the eave side and the lower surface of the end portion of the solar cell module main body are bonded and fixed by the adhesive member, rainwater or the like is transmitted through the adhesive member to the solar cell. It is possible to prevent the module body from entering the lower surface side.
