Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a solar cell panel laid on a lower ground such as a roof or a wall, in which the workability at the time of mounting the solar cell panel is remarkably improved. It is easy to maintain.

[0002]

BACKGROUND OF THE INVENTION conventional, there is a lighting frame or the like of a roof of Japanese open flat No. 3-241157 as a solar cell panel and its mounting structure.

This lighting frame has a structure in which a translucent plate supporting bar is attached along the inner surfaces of a pair of left and right vertical bars, and a lower horizontal bar is installed between the front ends of the translucent plate supporting bars. An upper cross rail is installed between the rear ends of the light transmissive support rails, and a light transmissive plate is stretched inside the space formed by these translucent plate support rails and the upper horizontal rail and the lower horizontal rail. The horizontal rail has a fitting recess formed at the lower front end thereof to be fitted to the upper horizontal rail, and has a photovoltaic element for converting solar energy into electric energy at the lower portion.

The fitting recess of the lower horizontal rail and the upper horizontal rail are fitted to overlap the lighting frames, thereby closing the gap between the lighting frames adjacent to each other in the eaves direction and not reducing the area of the translucent plate. I am trying.

However, since the fitting recess of the lower horizontal rail and the upper horizontal rail are fitted to overlap the lighting frame, that is, the solar cell panel, the mounting direction of the solar cell panel is only from the underwater side. Since it is limited, there is a problem that it cannot respond to the situation at the construction site (due to the progress of other payments).

Moreover, after the construction of the solar cell panel, if some of the solar cell panels are damaged or malfunction, only the solar cell panel cannot be replaced. That is, in order to replace it, it is necessary to temporarily remove all the solar cell panels on the water side of the row of the corresponding solar cell panel, and then replace the corresponding solar cell panel, which is a significantly large task. There is. In addition, as a matter of course, there is a problem that the amount of power generation decreases in proportion to the number of removed solar cell panels, and in particular, the larger the laying surface of the solar cell panel, the greater the problem.

[0007]

The problem to be solved is that the mounting direction of the solar cell panel on the base is limited to only one direction from underwater to above water.
It is a point that the maintenance of the solar cell panel cannot be performed by detaching and attaching only the relevant panel individually.

[0008]

In order to solve the above-mentioned problems, the present invention has a structure in which a solar cell panel is attached to an exterior base of a building, in which a base is provided with a fixed portion and a water side is provided with an engaged portion. , The holding surface formed on the underwater side, the holding rail formed respectively, the engaging portion corresponding to the engaged portion on the back side near the underwater side end, slide the engaging portion to the underwater side. A rectangular solar cell panel provided so as to be engageable with the engaged portion, and a short width joint cover formed in substantially the same shape as the surface shape of the solar cell panel. Orthogonally to the solar cell panel, the solar cell panel is laid and fixed at an effective length interval, and the solar cell panel is detachably engaged with the engaged portion and is mounted on the mounting surface portion. Also, it can move to the water side along the mounting surface until the engaging part disengages from the engaged part. Such water under side of the solar cell panel water upper end on with polymerizing solar panel water lower end of the water side, the space between laterally adjacent solar panels,
It is characterized in that it is closed by the joint cover that is removably covered by a fixing tool over the side edges of the left and right solar cell panels.

Further, according to the present invention, the holding rail is formed with the sub-engaged portion relatively to the engaged portion and facing the mounting surface portion, and the solar cell panel is formed on the water side above the sub-engaged portion. A corresponding sub-engaging portion is provided so that the sub-engaging portion can be slid to the water side to engage with the sub-engaged portion, and the sub-engaging portion is detachably engaged with the sub-engaged portion. It is characterized by having done.

Further, according to the present invention, an abutting portion which comes into contact with the holding rail is formed on the water side of the joint cover,
The abutting portion is brought into contact with the holding rail to restrict movement of the solar cell panel to the water side.

Further, according to the present invention, an abutting portion which comes into contact with the holding rail is formed on the attachment body on the back side of the joint cover in the fixture, and the abutting portion is brought into abutment with the holding rail so that the solar cell panel above the water surface. It is characterized by restricting movement to the side.

The holding rail in the present invention is a long one made of a synthetic resin material or a metal material formed by press molding or extrusion molding. The solar cell panel is, for example, a translucent plate provided with a solar cell on the back surface and is formed by surrounding the periphery of the translucent plate with a frame, and the engaging portion and the sub-engaging portion, and the engaged portion and the sub-engagement portion. The joint portion may be a separate body or may be formed integrally with the frame body of the solar cell panel. Furthermore, an appropriate waterproofing means such as a gasket or a packing may be interposed between the frame body and the joint cover in the solar cell panel to prevent rainwater from entering the rear surface of the panel.

The fixture for the joint cover is selected from known appropriate elements capable of attaching the joint cover over the side edges of the left and right solar cell panels. For example, a screw for directly fixing the joint cover to the side edge of the frame body on the left and right solar cell panels, or a separate engaging portion and sub-engaged portion, and further sub-engagement on the frame side edge. The left and right extending portions formed by extending outward from the portion and the sub-engaged portion may be sandwiched between the joint cover and the mounting body and fixed by screws. Further, the extending portion may be formed by integrally extending from the frame body of the panel.

[0014]

[Function] By sliding the solar cell panel under the water with respect to the holding rail, the engaging portion on the underwater side of the panel engages with the engaged portion of the holding rail to hold the underwater side of the panel. Since the held panel water lower end holds the lower panel water upper end between the panel surface and the mounting surface, the mounting direction of the solar cell panel is changed from the lower water side to the upper water side. Or vice versa, from above water to below water,
It can be installed and installed from either.

If the mounting direction of the holding rail and the solar cell panel is, for example, from underwater side to overwater side, the holding rail can be used as a foothold for the mounting work. Therefore, even if the inclination of the base is steep, Work can be performed safely and efficiently.

The solar cell panels are individually engaged and fixed to the holding rails, and the space between the left and right adjacent solar cell panels can be appropriately removed over the side edges of the left and right solar cell panel surfaces with a fixing tool. Since it is closed with the covered joint cover, at the time of replacement or maintenance of the solar cell panel, it is possible to easily replace or maintain the panel by removing only the joint cover on the side edge of the panel. .

Since the panel is not tightly fixed to the holding rail by screwing or the like, and is engaged and fixed relatively with play by sliding, it is affected by thermal expansion and contraction or displacement such as earthquake. In addition, no stress is generated in each member and the member is not damaged.

The holding rail is formed by making the sub-engaged portion relatively to the engaged portion and facing the mounting surface portion, and the solar cell panel is on the water side and the sub-engaging portion corresponding to the sub-engaged portion. The sub-engaging portion is slidably provided on the water side so as to be engageable with the sub-engaged portion, and the sub-engaging portion is detachably engaged with the sub-engaged portion. The solar cell panel is engaged with both the water side and the water side of the holding rail, and the mounting strength is strong and excellent.

The joint cover has an abutting portion on the water side that abuts against the holding rail. By abutting the abutting portion on the holding rail, movement of the solar cell panel to the water side is restricted. Therefore, the engagement relationship between the engaged portion of the holding rail and the engaging portion of the solar cell panel is fixed, and the solar cell panel does not come off from the holding rail. Moreover, the locked state of the solar cell panel can be easily unlocked by removing the joint cover that covers the side edge of the panel.

By moving the solar cell panel to the water side by forming an abutting portion that abuts on the holding rail on the attachment body on the back side of the joint cover of the fixture, and abutting the abutting portion on the holding rail. Since the engagement is restricted, the engagement relationship between the engaged portion of the holding rail and the engaging portion of the solar cell panel is fixed, and the solar cell panel does not come off from the holding rail. Moreover, the locked state of the solar cell panel can be easily unlocked by removing the attachment body of the fixture that fixes the joint cover to the panel.
