2. Description of the Related Art Conventionally, as a roof structure with a solar cell,
It is known to have various structures such as mounting a solar cell on a roof tile, or mounting a solar cell panel in which the solar cell is mounted on a frame material on a pedestal provided on the roof. A structure is often adopted in which a plurality of battery panels are directly attached onto a roof base material. The roof structure with solar cells in which multiple solar panels are directly attached to the roof base material is convenient because it does not require a pedestal.
There is a problem that rainwater leaks between the adjacent solar cell panel and another solar cell panel and enters the roof substrate.

In order to solve such a problem, various attempts have been made to prevent rainwater from entering between the adjacent solar cell panel and another solar cell panel. For example, JP-A-7
In JP-180310, a rail-shaped support member that supports both sides of a solar cell panel and a rail-shaped support member that supports both sides of another solar cell panel adjacent to this solar cell panel are adjacent to each other. The waterproof structure of the solar cell panel seam is described in which the mounting and the packing member are interposed between the support member and the adjacent support member, and the waterproof tape is applied across both of the support members for waterproofing. There is. With the waterproof structure of this solar panel seam,
Since the double waterproof structure such as the waterproof tape and the packing material is provided, the waterproof structure is extremely excellent, and the rainwater does not leak between the adjacent solar cell panels, which is a preferable structure.

[0004]

However, with the waterproof structure of the solar cell panel joint described in the above publication, the following problems occur after a long period of time. That is, in the roof structure with a solar cell, a wind may blow on the solar cell panel or a person may rise on the solar cell panel in order to repair the solar cell panel during a long period of time. At that time, a large force is applied to the solar cell panel, and the solar cell panel often moves.

On the other hand, most of the supporting members are often aluminum molded products due to the problem of strength for supporting the solar cell panel, and have a low followability to deformation. Therefore, when the solar cell panel moves, the supporting member also moves at the same time, and the distortion of this movement concentrates on the waterproof tape. When the strain concentrated on the waterproof tape is repeated, the waterproof tape is destroyed.

Further, when the solar cell panel moves, a gap also occurs between the packing material and the support member interposed between the adjacent support members, and the watertightness between the two becomes poor. . In this way, both waterproof tape and packing material,
The watertightness becomes inferior over a long period of time, and there arises a problem that rainwater permeates the roof base material from between the adjacent support members.

Further, when the roof panel or the roof unit is manufactured in the factory and the solar cell panel is mounted on the roof where the roof panel or the roof unit is assembled at the construction site, in order to reduce the construction site man-hour, A method in which a solar cell panel is mounted on a roof panel or a roof unit and only installed at a construction site is preferable. Thus, when the solar cell panel is mounted on the roof panel or the roof unit in the factory, there are the following problems.

That is, usually, a roofing material is laid on the roof base material to improve the waterproof property, but in order to do so, it is necessary to lay the roofing material before mounting the solar cell panel in the factory. is there. Then, at the construction site, it is necessary to connect the roofing materials of the adjacent roof panels or roof units, but the roofing materials are connected in the narrow gap between the adjacent roof panels or the adjacent solar cell panels attached to the roof unit. It is extremely difficult to work together.

[0009] Therefore, an object of the present invention is to provide a roof structure with a solar cell capable of maintaining waterproofness even after a long period of time, and a construction method for the solar cell roof structure, particularly in a factory, a solar cell panel. It is intended to provide a roof structure with a solar cell suitable for manufacturing a roof panel or a roof unit attached with, and assembling the roof panel or the roof unit on the roof at a construction site, and a construction method thereof.

By performing the construction in this manner, the space between the rising portions of the adjacent metal plates is waterproofed with the waterproof tape.
At this time, the waterproof tape can be pulled out from between the solar cell panels and adhered. By doing so, the workability is further improved, and the close contact can be ensured, and the reliability is improved.

Further, the cover material is bridged between the upper surface of the frame material of the solar cell panel and the upper surface of the frame material of another solar cell panel attached to the adjacent roof panel or roof unit, and the adjacent roof is provided. Since the panel or the roof unit is installed in a state where it covers the gap between the solar cell panels, rainwater that falls between the adjacent solar cell panels is blocked by the cover material, and the roof is removed from between the adjacent solar cell panels. Does not penetrate above the base material.

Between adjacent solar cell panels in this way,
Since the waterproof structure is provided in double with the cover material and the waterproof tape, rainwater does not enter the roof base material from between the adjacent solar cell panels. In this way, rainwater does not enter between the adjacent solar cell panels, so it is not necessary to lay the roofing material on the roof base material. Therefore, even in the case of a roof panel or a roof unit in which a roofing material is laid on a roof panel or a roof base material of a roof unit and a solar cell panel is mounted thereon, it is not necessary to connect the roofing material, and construction is easy.

Further, since the solar panel is attached to the roof panel or the roof unit at the factory, it is possible to obtain a roof structure with a solar cell at the construction site simply by installing the roof panel or the roof unit. On-site construction man-hours are reduced.

Further, wind may be blown on the solar cell panel or a person may climb onto the solar cell during a long period of time. At that time, the solar cell panel is moved. Even if the solar cell panel moves due to force, the waterproof structure between the cover material and the solar cell panel does not change the relative position between the cover material and the solar cell panel. It covers the space between adjacent solar cell panels, and the waterproof structure with waterproof tape is that the protruding edges of both waterproof tapes are brought into close contact with and adhere to each other. There is play, and the metal plate to which the waterproof tape is attached is bent, so that the solar battery panel and the metal plate move due to the movement of the solar battery panel due to the play of the waterproof tape and the bending of the metal plate. Between Distortion that occurs is absorbed, waterproof tape is not damaged. Thus, even if it is used for a long period of time, since the double waterproof structure is not destroyed, rainwater does not leak from between the adjacent solar cell panels onto the roof base material.
