DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photovoltaic panel mounting roof structure having good waterproof, fireproof and workability.

[0002]

2. Description of the Related Art In recent years, solar power generation panels (a), which are clean energy, have been mounted on roofs or the like of houses due to increasing interest in the global environment such as energy saving and prevention of global warming. This solar panel (a)
For example, as shown in FIG.
The four sides of the photovoltaic power generation unit (b) formed by a number of amorphous condensing cells are reinforced with a metal frame (c) such as aluminum or stainless steel, the front surface is protected by tempered glass (d) and the back surface is protected. The above frame (c)
And has a back surface space (e) surrounded by.

[0003] The solar power generation panel (a) is mounted on a metal roofing plate such as a cement-based flat roofing plate or a galvanized iron plate which is constructed as a roof finishing material (g) on a field board (f). The vertical beam (h) is fixed, and the frame (c) of the photovoltaic power generation panel (a) is mounted on a stand formed by fixing the horizontal beam (i) on the vertical beam (h). ing.

[0004] However, the roof structure (A) to which such a conventional solar power generation panel (a) is attached is constructed by installing both the roof finishing material (g) and the photovoltaic power generation panel (a). Since it is formed, there is a problem that it takes much time for construction and is uneconomical.

For this reason, recently, after roofing is laid on the ground board, a gantry composed of the vertical rail (h) and the horizontal rail (i) is fixed directly on the roofing material (g) without applying the roof finishing material (g). In some cases, a photovoltaic power generation panel (a) is attached and fixed to the mount.

[0006]

In the former case, since the solar panel (a) is installed on the roof finishing material (g), the basic performance required for the roofing material such as fire resistance and waterproofness is required. However, there is a disadvantage that the above-mentioned double roof structure is provided.

[0007] In the latter case, the photovoltaic panel (a) which is a substitute for the roof finishing material (g) is mounted on the roof foundation without applying the roof finishing material (g). There is a problem that water and the like easily enter the space on the back surface of the power generation panel (a), and fire resistance and waterproofness are reduced.

In the former case as well, in the latter case, in particular, the temperature of the back space of the photovoltaic power generation panel (a) tends to rise, and the photovoltaic power generation part (b) is of a single crystal type or polycrystalline type. In the case of a light-collecting cell made of crystal-type silicon, there is a problem that the power generation efficiency is significantly reduced when the temperature is increased.

[0009]

In order to solve the above-mentioned problems, a roof structure according to the first aspect of the present invention has a roofing material having a nail hole sealing property mounted on a noncombustible ground plate, and the roofing material is provided with the roofing material. And a photovoltaic power generation panel with a four-circle frame was mounted on the back with a back space provided on the back.

Further, the roof structure according to the second aspect of the present invention is configured such that the back space communicates with the outside air through ventilation portions provided on at least two opposing frames of the four-circle frame of the photovoltaic panel. .

[0011]

According to the first aspect of the present invention, a roofing material having a nail hole sealing property is mounted on a non-combustible base plate.
Since it has both fire protection and waterproofness, and it is not necessary to construct a roof finishing material such as a cement-based flat shingle, it can be formed economically and with good workability.

According to the second aspect of the present invention, since the back surface space is formed so as to communicate with the outside air, especially when the condensing cell is formed of a silicon single crystal or polycrystal type, the hot air which accumulates in the back surface space is formed. Can be diffused to the outside, and a decrease in power generation efficiency due to a rise in temperature can be reduced.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a photovoltaic panel mounting roof structure according to an embodiment of the present invention.

In FIG. 1, (1) is a roof structure with a solar panel mounted thereon, and a non-combustible base plate (3) is fixed on a rafter (2) with nails or screws. A roofing material (4) having a nail hole sealing property is laid and constructed on 3), and a vertical rail (5) is fixed on the roofing material with nails or screws.
A horizontal rail (6) in a direction orthogonal to the vertical rail (5) is fixed with nails, screws, or the like, and a solar power generation panel (7) is mounted and fixed to the horizontal rail (6). ing.

Examples of the non-combustible base plate (3) include quasi-non-combustible materials such as ALC, calcium silicate plate, wood chip cement plate, and volcanic glassy multi-layer plate (trade name: Dailite, manufactured by Daiken Kogyo Co., Ltd.) or non-combustible materials. Materials can be used.

The roofing material (4) having a nail hole sealing property is an asphalt-based roofing material, particularly a rubber-asphalt-based roofing material or another polymer-modified asphalt-based roofing material. It is possible to use a material in which a part of the roofing material is deformed viscoelastically and seals around a nail or a screw that has been driven to exhibit watertightness.

The vertical bar (5) may be made of a wood material, or a metal material such as aluminum or stainless steel. In the case of a wood material, a narrow plate or a rod is used, and in the case of a metal material, Can be used, such as a C-shaped, B-shaped, or H-shaped bar.

As the cross rail (6), a rod-shaped cross section made of a metal material such as aluminum or stainless steel having a C-shaped, B-shaped or H-shaped cross section or a modified shape thereof can be used.

As shown in FIG. 2, a photovoltaic power generation panel (7) is a photovoltaic power generation section (FIG. 2) in which a predetermined number of light-collecting cells in which amorphous, monocrystalline, and polycrystalline silicon wafers are integrated are formed into a module. 8), a tempered glass (9) for transparently protecting the upper surface of the power generation unit (8), and a metal frame (10) for surrounding and protecting these four circumferences are used. be able to.

Since the frame portion (10) is formed to be thicker than the photovoltaic power generation portion (8), the frame portion (1) is provided on the back side of the photovoltaic power generation portion (8).
A back space (11a) surrounded by 0) is formed.
The back space (11a) is connected to the back space (11b) between the vertical bar (5) and the non-combustible base plate (3) on which the roofing material (4) is laid and constructed, and the back space is combined. Is formed.

FIG. 3 shows a photovoltaic panel (7 ') showing a modified example. A ventilation portion communicating with a back space (11a) is provided in a frame portion (10') of the photovoltaic panel (7 '). (12) is provided to prevent the temperature of the back surface space from excessively rising by communicating with the outside air, thereby preventing a decrease in power generation efficiency.

[0022]

As described above, in the roof structure for mounting a solar panel according to the present invention, since a roofing material having a nail hole sealing property is mounted on a non-combustible ground plate, heat in a fire or the like is reduced. Even if it enters the back space of the solar power panel, it can exhibit fire protection, and even if rainwater enters the space, the nail hole of the roofing material is sealed, so rainwater does not enter the roof interior It can exhibit waterproofness.

Since there is no need to construct a roofing material such as a cement flat roofing material or a metal roofing material,
The workability and economy can be formed well without the roof structure of heavy equipment. In addition, if a back surface space is provided on the back surface of the photovoltaic power generation panel, a rise in temperature can be suppressed, so a decrease in power generation efficiency can be suppressed, and the back space is formed so as to communicate with outside air. By doing so, it is possible to more favorably suppress a rise in temperature and suppress a decrease in power generation efficiency.
