Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a house outer surface structure and a solar structure in which a plurality of solar energy modules (solar cell modules, solar water heater modules, etc.) are installed on the outer surface of a roof or outer wall of a house. The present invention relates to a cell roof structure and a solar cell roof construction method for obtaining this solar cell roof structure. In particular, the present invention relates to measures for ensuring a good external appearance of a house.

2. Description of the Related Art Unlike conventional thermal power generation that burns fossil fuels such as petroleum and nuclear power generation that is difficult to dispose of waste, it uses clean solar energy that has very little impact on the global environment. A solar cell that does is known.
In recent years, this solar cell is being used in general houses as the price decreases. By providing such an in-house power generation facility using solar cells, it becomes possible to obtain electric power during the day without requiring power transmission from an electric power company. Moreover, when surplus power is generated during daytime power generation, it is possible to sell this surplus power to a power company.

Further, conventionally, when a solar cell is provided on a roof of a house, it has been generally practiced to install the solar cell on a roof tile. This is because the conventional solar cells do not have sufficient fire resistance, and thus roof tiles are required to secure the fire resistance of the roof portion of the house.

However, in recent years, with the improvement of the fire resistance of the solar cell, it has become possible to directly sew the solar cell as a roofing material without using a roof tile. For example, Japanese Patent Application Laid-Open No. 11-100962 discloses a configuration in which a support rail is installed on a waterproof sheet of a roof and a solar cell is fixed on the support rail. As a result, roof tiles are not required in the roofing portion of the solar cell, the construction cost of the house can be reduced, and the construction period can be shortened.

[0005]

By the way, in the case where the solar cells are directly roofed as the roofing material as described above, a plurality of solar cell modules are arranged in order on the roof frame. The optimum roof structure and roof construction method in that case have not been proposed yet.

The inventors of the present invention have considered the optimization of a roof structure and a roof construction method when a solar cell module of this type is installed. Then, in particular, the caving structure of the solar cell module located closest to the ridge among the plurality of solar cell modules arranged on the roof is considered.

When a plurality of solar cell modules are arranged in the roof inclination direction, in a solar cell module other than the solar cell module located closest to the ridge, another solar cell module is adjacent to the ridge side. There is. for that reason,
The ridge-side edge of this solar cell module can be locked or fixed to the eave-side edge of the ridge-side solar cell module. For example, when the peripheral edge of each solar cell module is made of a frame material, the frame materials of the solar cell modules can be connected to each other. Thereby, each solar cell module can be installed with a feeling of continuity, and each solar cell module can be stably installed while obtaining a good appearance.

However, in the solar cell module located closest to the ridge, the solar cell module is not adjacent to the ridge side. Therefore, the boundary between the ridge-side edge of this solar cell module and the field plate is exposed, and a good appearance cannot be obtained. In addition, there is still room for improvement in the structure for stably installing the edge of the solar cell module on the ridge side on the roof frame.

Further, the above-mentioned problems are also caused when not only the solar cell module but also the solar water heater module is installed. Further, the solar cell module and the solar water heater module are not only installed on the roof part of the house but also attached to the outer wall of the house in some cases.

The present invention has been made in view of the above points, and an object thereof is to provide a plurality of solar energy modules (solar cell modules or solar water heater modules) on the roof of a house or on the outer wall of a house. On the occasion of
Structure for stably installing this solar energy module while ensuring good appearance of the peripheral part of the solar energy module located on the uppermost side (ridge side on the roof) and construction method for obtaining the structure To provide.

[0011]

Means for Solving the Problems-Outline of the Invention-To achieve the above object, the present invention provides a plurality of solar energy modules (solar cell modules or solar water heater modules) on the roof of a house or on the outer wall of a house. At the time of providing, the upper edge of the solar energy module located at the uppermost side is covered with another member, and the upper edge of this solar energy module is fixed to the outer surface of the house by utilizing this other member.

[0012]

[0013] - SOLUTION - Specifically, first solving means taken by the invention, assume a solar cell roof structure formed by installing a plurality of solar cell modules on the Koyagumi of houses. With respect to this solar cell roof structure, the ridge-side edge of the solar cell module located closest to the ridge among the solar cell modules is covered with a cover plate supported by the roof frame. Further, a connection member that forms an insertion space that opens to the eaves side between the cover plate and the eaves side edge of the cover plate is attached. Further, by narrowing the gap between the cover plate and the connecting member in a state where the ridge-side edge of the solar cell module located closest to the ridge is inserted in the direction from the eaves to the ridge with respect to the insertion space, The ridge-side edge of the solar cell module is sandwiched by this cover plate and the connecting member.

Due to these particulars, the upper edge of the uppermost solar energy module is covered by the cover plate. That is, since the boundary portion between the upper edge of the solar energy module and the outer surface of the house becomes invisible, the appearance of the outer surface of the house is favorably secured.
The cover plate is supported on the outer surface of the house and holds the upper edge of the solar energy module. Therefore, the upper edge of the solar energy module is supported on the outer surface of the house through the cover plate. Therefore, with this cover plate, it is possible to improve the appearance of the outer surface of the house and secure a stable installation state of the solar energy module. Also, for the cover plate
When locking the ridge-side edge of the solar cell module, in advance,
Widen the insertion space between the cover plate and the connecting member.
Keep it. In this state, the edge of the solar cell module on the ridge side
Insert it into the insertion space and connect the cover plate to the connecting member.
Close the space. As a result, the ridge side edge of the solar cell module
The rim is sandwiched between the cover plate and the connecting member,
Do not hold the battery module on the cover plate.
It In this way, keep the distance between the cover plate and the connecting member.
Located relatively to the ridge, with a relatively simple work such as narrowing
The solar cell module is installed through the cover plate
Can only support you.

The second solution is to specify the shape of the cover plate. That is, in the first solution, the cover plate is formed in a shape that smoothly connects the ridge-side edge of the solar cell module and the ridge of the house.

[0016] Due to this specific matter, the ridge-side edge of the solar cell module located closest to the ridge and the ridge of the house are smoothly connected by the cover plate, and the appearance of the ridge of the roof is better secured. it can.

[0017]

[0018]

The third means for solving the problem is to specifically specify the structure for supporting the cover plate on the roof frame. That is, in the first or second solving means, a plurality of cover plates are joined together in the house girder direction. A connecting plate for connecting the cover plates to each other is provided in the connecting portion so as to straddle the cover plates adjacent to each other. Then, this connecting plate is fixed to the roof frame.

Due to this particular matter, the connecting plate has not only the function of connecting the cover plates adjacent to each other, but also the function of supporting these cover plates on the roof frame. That is, it is possible to obtain both of these functions with one member.

A fourth solving means relates to a construction method for obtaining the above solar cell roof structure. In other words, it is premised on a method of constructing a solar cell roof, which is constructed by installing a plurality of solar cell modules on the roof of a house. A cover plate supported by the cottage is disposed on the ridge of the cottage, and a connecting member is attached to the eave side end of the cover plate. This connecting member forms an insertion space that opens to the eaves side with the cover plate.
Then, the inserting operation is performed in which the ridge-side edge of the solar cell module located closest to the ridge is inserted into the inserting space in the direction from the eaves toward the ridge. After that, by narrowing the gap between the cover plate and the connecting member, the ridge-side edge of the solar cell module is clamped by the cover plate and the connecting member.

Due to these specific matters, it is possible to obtain a method of constructing a solar cell roof that can improve the appearance of the ridge and ensure a stable installation state of the solar cell module . A fifth solution means is a house having a roof having a solar cell roof structure according to any one of the first to third solution means. A sixth solving means is a house having a roof constructed by the solar cell roof construction method according to the fourth solving means.
