Description

BACKGROUND OF THE INVENTION
The present invention relates to a building board constituting an enclosure such as a roof or a wall, wherein the building board is long in the longitudinal direction and can be linear or curved along the longitudinal direction. The present invention relates to a building plate with a solar cell in which a flat plate-like hard solar cell is mounted on a plate, and a large roof, a wall and the like can be constructed.
[0002]
[Prior art]
Conventionally, there are architectural boards such as roof boards equipped with solar cells. Many of these are mounted on places such as a main plate of a building board that are most easily mounted and where sunlight is likely to hit efficiently. Moreover, the solar cell is mounted on the building board by various means. In addition, some of the building boards are formed of a metal material by a roll forming machine, and an extremely long board can be formed by this type of manufacturing means. Due to such long building boards, large-scale buildings on which roofs or walls are constructed are also increasing.
[0003]
Thus, an extremely long building board shall be a curved building board having a very large radius of curvature along its longitudinal direction, and construction of arched roofs, walls, etc. shall be performed with this building board. You can also. Assuming that a solar cell is mounted on such a long or arched building board, the curved surface of the building board can be deformed into a curved shape so as to have the same curvature. There is something that can be used, and it is used for long building boards. Most solar cells mounted on this type of building board are thin, flexible and deform with the deformation of the building board.
[0004]
By the way, as shown in the following patent document 1 or the like, some solar cells use tempered glass as a front cover. This is called a glass substrate solar cell, and the solar cell part is protected by the tempered glass, and sunlight can be sufficiently absorbed by the translucency of the tempered glass. By the way, since the tempered glass has a plate thickness, it is a hard member that is naturally flat and cannot be deformed at all. For this reason, there has been no long-standing building board equipped with a hard solar cell using the tempered glass as described above.
[0005]
[Patent Document 1]

[0006]
[Problems to be solved by the invention]
As in Patent Document 1, a solar cell using tempered glass has not only excellent durability but also extremely good sunlight absorption. However, this type of solar cell is used for a building plate having a flat surface, and to be used for an arched roof or the like, the tempered glass is flat and cannot be deformed. Can not. Therefore, conventionally, there is only a structure in which a rigid solar cell is mounted on a building plate that is relatively short and specifically has a length in the longitudinal direction of about 2 meters or less.
[0007]
Such short building boards must be connected in the longitudinal direction to construct large roofs and walls, etc., so the number of connection points between the building boards in the longitudinal direction increases, and the construction is troublesome. Not only that, but because the number of connection points increases, the risk of leakage of rainwater from the connection points also increases. The object of the present invention is to install a plurality of hard flat plate-like solar cells in which tempered glass is incorporated into a long building board, and to make the building board curved in the longitudinal direction as necessary. An object of the present invention is to provide a building board with a solar cell, which can efficiently construct an enclosure such as a large roof or wall.
[0008]

And a frame that supports the periphery of the solar cell, the frame is fixed to the main plate together with the solar cell, a recess for inserting a seal material is formed on the back side of the frame, and the seal material is inserted. Plate for solar cell construction in which a frame seal material is mounted between the main recess and the main plate, and a hard plate shape so A solar cell that is fixed to a building plate having a main plate having connecting bending portions formed on both sides in the width direction, and a frame that supports the periphery of the solar cell and is fixed to the main plate, By forming a recess for sealing material insertion on the back side of the frame, and a solar cell device in which the frame sealing material is mounted between the recess for inserting sealing material and the main plate, for long construction A plurality of hard flat plate-like solar cells with tempered glass incorporated into the plate are attached at predetermined intervals, and the building plate can be bent in the longitudinal direction without difficulty, as required.
