Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a building outer wall panel used as a waist of a curtain wall or an outer wall of a house.

[0002]

[Prior art]

 It has been a common practice to install solar panels in buildings to use solar energy as electric power. For example, a solar cell panel may be mounted on a roof of a building or the like via a pedestal or a frame, or as shown in Japanese Utility Model Laid-Open No. 1-94590, a solar cell panel may be mounted in a shoji forming a sash. As shown in Japanese Patent No. 11261, a roof tile body is attached with a solar cell panel to form a roof tile.

[0003]

[Problems to be solved by the device]

 When a solar cell panel is mounted on a roof, the cost is high because a pedestal or frame is required, and the solar cell panel is visible from the outside, making the exterior design of the building difficult to see. When a solar cell panel is installed inside the shoji screen of a sash, the solar cell panel becomes small because the installation area is small, and solar energy cannot be effectively used. When a solar cell panel is attached to the roof tile, the roof can be constructed by simply attaching the roof tile, and at the same time the solar cell panel can be placed on the entire roof, but the roof tile itself is heated by sunlight and becomes hot. Therefore, the temperature of the solar cell panel also becomes high and the efficiency of converting solar energy into electric power deteriorates.

Therefore, an object of the present invention is to provide a panel for a building outer wall that can solve the above-mentioned problems.

[Work]

 Since the solar cell panel 4 can be mounted on the building by mounting the panel 1 for the outer wall of the building, no special mounting member is required, and the appearance design of the building is not unsightly. Moreover, since the fins 2 increase the heat dissipation area of the panel body 3, the panel body 3 is not sufficiently cooled and the temperature does not rise, and the solar cell panel 4 can efficiently convert solar energy into electric power. However, since the panel body 3 is reinforced by the fins 2 and has a large rigidity, the wind pressure resistance is improved, and the extrudability does not bend and the formability is improved. If the cooling gas / fluid is circulated in the flow passage cavity 24 of the panel body 3 to cool the panel body 3 sufficiently, the temperature of the panel body 3 does not rise and the solar cell panel 4 causes the solar cell panel 4 to cool. Energy can be efficiently converted into electric power, and the flow passage cavity 24 can increase the rigidity of the panel body 3.

【Example】

 FIG. 1 shows a part of a building outer wall, and the building outer wall A is constructed by arranging a plurality of building outer wall panels 1 vertically and horizontally. As shown in FIG. 2, the building exterior wall panel 1 is a panel body 3 having a plurality of fins 2 on the back surface, and a solar cell panel 4 attached to the surface thereof. It is installed diagonally so that the upper part is on the indoor side.

As described above, since the heat dissipation area of the panel body 3 is increased and the temperature rise of the panel body 3 due to the solar energy can be reduced, the solar cell panel 4 does not become a high temperature and the solar energy is efficiently emitted. Can be converted to electricity.

Next, a specific example of the building outer wall panel 1 will be described with reference to FIG. The panel body 3 is formed by aluminum extrusion molding, press molding, roll molding, or the like, and is provided integrally with a vertical plate 6 having fins 2 on the back surface and a concave portion 5 on the front surface, and an upper end portion of the vertical plate 6. A vertical plate 6 comprising an upper mounting plate 7, a horizontal plate 8 integrally provided at the lower end of the vertical plate 6, and a lower mounting plate 9 integrally downwardly provided at the end of the horizontal plate 8. The upper mounting plate 7 is at an angle smaller than 90 degrees with respect to the horizontal plate 8, that is, oblique to the vertical, the upper mounting plate 7 and the lower mounting plate 9 are parallel, and the lower mounting plate 9 is more than the upper mounting plate 7. Is located closer to the indoor side. The solar cell panel 4 is mounted in the recess 5 of the vertical plate 6 and covered with a transparent plate 10 such as a transparent resin plate or a glass plate.

Because of this, the building exterior wall panels 1 that are vertically adjacent to each other are connected by connecting the lower mounting plate 9 and the upper mounting plate 7 to each other, and the horizontal plate 8 is horizontally mounted to connect the solar panels. The battery panel 4 is inclined vertically so that it is on the indoor side, so that the solar cell panel 4 is efficiently irradiated with sunlight. Further, since the panel body 3 is reinforced by the fins 2 and becomes highly rigid, the wind pressure resistance is improved when the panel body 3 is attached to the building frame, and the extrusion moldability is improved without bending when the panel body 3 is extrusion-molded. To do.

To mount the building outer wall panel 1 to the building frame, for example, the lower mounting plate 9 of the lowermost building outer wall panel 1 is mounted to the building body via a fastener, and then the building outer wall panel 1 is sequentially mounted. The upper mounting plate 7 of the panel 1 for the outer wall of the uppermost building is connected to the upper part of the building with fasteners.

Next, a second embodiment will be described. As shown in FIG. 4, screw holes 20 are integrally formed in the corners of the upper mounting plate 7 and the fin pieces 2 and in the corners of the horizontal plate 8 and the vertical plate 6 in the longitudinal direction. By doing so, the wiring 21 for electric power can be arranged in the screw hole 20 and connected to the solar cell panel 4, so that the wiring 21 can be protected and the wiring 21 can be easily attached to the panel body 3. Can be installed.

Next, a third embodiment will be described. As shown in FIG. 5, an upward fitting groove 22 is formed in the lower part of the upper mounting plate 7, and the lower mounting plates 9 of the panel body 3 which are vertically adjacent to each other are fitted into the fitting groove 22 so as to be vertically adjacent. The panel body 3 is connected. In this way, the vertically adjacent panel bodies 3 can be connected easily and firmly.

Next, a fourth embodiment will be described. As shown in FIG. 6, a U-shaped plate 23 is integrally provided on the back surface of the vertical plate 6 to form a flow passage cavity 24 continuous in the longitudinal direction. By doing so, the panel body 3 can be sufficiently cooled by circulating the cooling gas and liquid in the flow passage cavity 24, so that the temperature of the panel body 3 does not rise and the solar cell panel 4 prevents The solar energy can be efficiently converted into electric power, and the rigidity of the panel body 3 can be increased.

[Effect of device]

 Since the solar cell panel 4 can be mounted on the building by mounting the panel 1 for the outer wall of the building, no special mounting member is required, and the appearance design of the building is not unsightly. Can be installed. Furthermore, since the fins 2 increase the heat radiation area of the panel body 3, the panel body 3 is sufficiently cooled and the temperature does not rise, and the solar cell panel 4 can efficiently convert solar energy into electric power. Moreover, the fins 2 increase the rigidity of the panel body 3 to improve wind pressure resistance, and the extrusion moldability is improved without bending during extrusion molding. In addition, the cooling gas / fluid can be circulated in the flow passage cavity 24 of the panel body 3 to sufficiently cool the panel body 3, so that the temperature of the panel body 3 does not rise and the solar cell panel 4 prevents the solar cell panel 4. Energy can be efficiently converted into electric power.
