2. Description of the Related Art In recent years, it has become popular to use a solar cell as a power source for the purpose of energy saving. In this case, in order to reduce the construction cost, it is desirable to finish the construction simply and in a short period of time.

The technology of the installation device to achieve this is
For example, JP-A-5-222807 and JP-A6-1-1.
It is proposed in Japanese Patent No. 36895. The former is configured such that a stepwise roof plate material is provided, and a solar cell panel is assembled to the roof plate material of each step from below.
In the latter, a holding rail is provided on the roof so as to be orthogonal to the water flow direction, and the solar cell panel can be mounted on the holding rail from both the underwater side and the waterside. It is a thing.

[0004]

However, in the installation devices of the above-mentioned publications, the solar cell panels are assembled from the upper side or the lower side of the roof. Therefore, at the time of assembling the solar cell panel, a holding component for opening the upper part or the lower part of the assembling position and closing the part after assembling to hold the solar cell panel is required. Therefore, in the techniques of both publications, the above-mentioned holding component that is separate from the component that supports the bottom surface of the solar cell panel is required, and the number of components is large, the configuration is complicated, and the weight is heavy.

Moreover, since the direction of assembling or removing the solar cell panel is the vertical direction, it is necessary to perform the work while resisting the weight of the solar cell panel, which compels the difficult work. .

Therefore, when assembling the installation device having the conventional structure or installing the solar cell panel, heavy equipment such as a scaffold or a crane may be required in some cases, and there is a problem that the construction is large and the construction is prolonged.

Moreover, it is to provide a device for installing a solar cell panel having excellent resistance to wind.

[0008]

In order to achieve the above object, in the invention according to claim 1, a bracket fixed to the outer surface of the building is provided, and the bracket includes:
A holding portion for holding the solar cell panel was provided, and the holding portion was opened laterally.

Therefore, the solar cell panel can be assembled and removed while sliding it from the lateral direction of the installation device. Therefore, in this installation device, there is no need for a component that opens or closes the upper part or the lower part of the mounting portion of the solar cell. In addition, since the moving direction when the solar cell panel is attached and detached is the lateral direction, it is not necessary to perform the work while resisting the weight of the solar cell panel. Further, the angle and height of the solar cell panel can be optimized by appropriately selecting the bracket.

According to a second aspect of the present invention, in the first aspect, a frame fixed to the outer surface of the building is provided, and the bracket is attached to the frame. Therefore, the brackets can be arranged at desired positions, for example, at regular intervals without being disturbed by the reinforcing bars of the building. Further, the load of the bracket, on which the weight of the solar cell panel is concentrated, can be dispersed by the frame, and it is possible to eliminate the need for reinforcement work or the like.

According to the invention described in claim 3, in claim 1 or 2, the bracket supports the solar cell panel from above and below. According to a fourth aspect of the present invention, in the third aspect, the bracket is configured to include one that supports the lower portion of the solar cell panel and one that supports the upper portion.

Therefore, by changing the installation intervals of the brackets, appropriately changing the angle of the holding portion, and selecting the required height, it is possible to cope with solar cell panels of different sizes. In addition, the optimum tilt angle can be secured.

According to a fifth aspect of the present invention, in any one of the second to fourth aspects, one of the frame and the bracket is formed with an opening, and the other is formed with a projecting piece that enters into the opening. An engaging piece that engages with the projecting piece is formed at the edge of the opening.

Therefore, the frame and the bracket can be temporarily assembled by the engagement of the projecting piece and the engaging piece, and the number of screwing points can be reduced to facilitate the construction.

The frame 11 and the first and second brackets 21 and 31 are made of a corrosion resistant material such as stainless steel or aluminum alloy.

In order to install the solar cell panel P on the roof using the solar cell panel holding device constructed as described above, first, the frames 11 are installed on the roof at equal intervals and fixed by the screws 13. Next, the first and second brackets 21 and 31 are alternately installed in the installation portions 22 and 32 so as to correspond to the openings 15, respectively. In this installed state, the projection pieces 23 and 34 elastically engage with the engagement piece 16 of the opening 15 to prevent rattling. The first and second brackets 21 and 31 are fixed by screws 33.

Then, the solar cell panels P are sequentially inserted laterally from the holding portion 41 at one end opened laterally to form a gap L between the adjacent solar cell panels P. Form a row. Therefore, both ends of the row of the solar cell panels P are closed and fixed by the end blocks 51, and the lateral movement is blocked.

When replacing the solar cell panel P, the existing solar cell panel P may be extracted laterally and a new solar cell panel P may be mounted in the same manner as described above. In this embodiment configured as described above, the following effects are exhibited. (1) While fixing the frame 11 to the roof of the building,
By assembling the brackets 21 and 31 on the frame 11, the installation device of the solar cell panel P can be extremely easily assembled to the building. Then, when assembling the solar cell panel P, it is extremely easy because the solar cell panel P is only inserted from the lateral direction of the holding portion 41 opened to the side. (2) The main parts for assembling the solar cell panel P are only the frame 11 and the brackets 21 and 31, and there is no need to open or close the top and bottom of the solar cell panel P. The number of points is small, the configuration is simple, and parts management is easy. Further, since the main parts are only the frame 11 and the brackets 21 and 31, the weight can be reduced. (3) Due to the effects of (1) and (2), heavy equipment such as a scaffold and a crane is not necessary when installing the installation device and the solar cell panel P. Therefore, the construction does not become large-scale and the construction period can be shortened. (4) Height of brackets 21, 31 and grips 24, 3
By appropriately selecting the angle of 5, the inclination angle of the light receiving surface Pa of the solar cell panel P can be freely set. Therefore, the optimum inclination angle can be secured according to the region and location conditions, and highly efficient power generation can be performed. (5) If the spacing between the openings 15 of the frame 11 is appropriately changed to change the spacing between the brackets 21 and 31, and if the brackets 21 and 31 having the gripping portions 24 and 35 at appropriate angles are selected, various types can be obtained. It is possible to correspond to the solar cell panel P having the size of. (6) Since the air vent gap L is formed between the adjacent solar cell panels P, it is possible to secure sufficient proof strength against strong wind. (7) By arranging the rows of the solar cell panels P in parallel at predetermined inclination angles,
Even if the height of the roof is lowered, the maximum light receiving area can be secured by effectively utilizing the rooftop area. That is, it is necessary to provide a space corresponding to the height of the solar cell panel in the front row between the solar cell panel and the rear solar cell panel when viewed from the sunlight irradiation direction so that no shadow is formed on the rear solar cell panel. Therefore, unlike the above-described embodiment, when the solar cell panel is raised to increase the light receiving area, the number of panels that can be installed is reduced, which is meaningless, and the wind receiving area is increased to prevent wind. The yield strength decreases. In the above embodiment, such a problem does not occur. (8) Since the brackets 21 and 31 are assembled to the building B via the frame 11, even if the reinforcing bars pass through the positions where the brackets 21 and 31 are installed, the brackets 21 and 3
1 can be placed in the required position. Therefore, the rows of the solar cell panels P can be set at equal intervals or arbitrarily, which can contribute to high-efficiency power generation and improvement of the appearance of the building.

4 and the engaging piece 16 on the side of the frame 11 engage with each other so that the frame 4 is held and temporarily assembled. Therefore, not only the positioning of the brackets 21 and 31 and the fixing by the screw 33 become easy, but also the screw 33
It is possible to reduce the number of steps, which facilitates construction and contributes to shortening the construction period. (10) Since the brackets 21 and 31 are assembled to the building B via the frame 11 as described above, the load of the brackets 21 and 31 receiving the weight of the solar cell panel P is dispersedly supported via the frame 11. Therefore, no reinforcement work is required and the construction period can be shortened.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIGS. In this embodiment, the solar cell panel P is mounted on the outer wall of the building.

That is, the frame 11 is fixed to the outer wall of the building so as to extend in the vertical direction.
