[0010]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment according to the solar power roof tile of the present invention will be described with reference to FIGS.
The structure of the photovoltaic power generation roof of the present invention is substantially the same as that of the prior application illustrated in FIGS. That is, first, a housing recess 3 that can accommodate the entire solar cell unit 2 having a rectangular flat plate surface is formed on the surface of the tile body 1, and is accommodated in two locations on the head side edge 31 of the housing recess 3. A locking recess 4 that fits and locks the head side edge 22 of the solar cell unit 2 so as not to fall off is formed integrally with the roof tile body 1.
[0011]
Next, in the present invention, as shown in FIGS. 5 (A) and 5 (B), a cover panel 7 that covers the entire bottom edge 23 of the solar cell unit 2 and the subsequent tile bottom of the roof tile body 1 is attached. It is. The cover panel 7 is provided with a nail hole 71 at a position corresponding to a tile fixing nail hole (not shown) on the tile side, and the roof panel 7 and the tile body 1 are fixed by the fixing nail when roofing. It is attached and fixed integrally.
[0012]
By using such a panel cover 7, as described above, it covers the bottom side of the tile body 1 including the output cable housing concave groove of the photovoltaic power generation unit 2, so that it is difficult for rainwater to enter and the internal output terminal In addition to protecting the box (not shown) and the output cable (not shown), the head side edge 73 is superimposed on the entire bottom edge 23 of the solar cell unit 2, so that the solar cell unit 2 is attached. Is to ensure.
[0013]
The most characteristic feature of the present invention is that the bottom edge 23 of the solar cell unit has a bottom side as shown in FIG. with the edge 23 comprises a housing capable U-shaped recess 74b, is inserted between the trailing edge 23 and the trailing edge wall 11 of the housing recess 3, the tip portion 74a is on the trailing wall 11 A preferred embodiment will be described below in that at least one locking metal fitting 74 that can be locked in the provided locking recess 11a is disposed in accordance with the set strength. Note that FIG. 1B corresponds to FIG.
[0014]
(First embodiment)
A first embodiment of the locking metal fitting 74 will be described with reference to FIG. This locking metal fitting 74 is an appropriately wide metal member. First, the metal member is formed with a U-shaped recess 74b bent into a U-shaped cross section, and the U-shaped recess 74b is attached to the roof tile body. The solar cell unit 2 has a concave shape that can be accommodated with the bottom edge 23 interposed therebetween. In this case, it is preferable to protect the bottom edge 23 by interposing the cushioning material 8.
[0015]
Next, a spring portion 74c that continuously hangs down from the U-shaped recess 74b is formed, and its end is folded back to reach the tip 74a. The distal end portion 74a can be locked while being urged by the elastic force of the spring portion 74c to the locking recess 11a provided on the bottom side surface 11 of the housing recess 3. Thus, according to this locking metal fitting 74, the photovoltaic power generation unit 2 can be fitted into the recess 74b and can be held more stably, and by the locking action of the tip end portion 74a, the bottom side of the solar cell unit 2 can be held. The fixing of the edge portion 23 is strengthened, and the advantage that the wind pressure resistance performance is further improved is obtained.
[0016]
According to this embodiment, after fitting the locking metal fitting 74 obtained by molding as described above with the bottom edge 23 of the solar cell unit 2 interposed therebetween, the entire photovoltaic power generation unit 2 is accommodated in the housing recess 3. If pushed in, the front end 74a of the locking metal fitting 74 is locked to the locking recess 11a provided on the bottom side surface 11 and can be easily fitted and finished. FIG. 3 shows an example in which the locking metal piece 74 is formed integrally with the cover panel 7. In this case, the photovoltaic power generation unit 2 is more reliably held, and the cover panel 7 is attached at the same time. There is an advantage that can be done.
[0017]
(Second Embodiment)
FIG. 4 illustrates the second embodiment. The locking metal member 74 is a metal member welded and joined to the back surface of the cover panel 7 by a welded portion 74d, and a bent portion 74e is formed by bending the suspended portion forward. It is formed in the recessed part which can be accommodated on both sides of the bottom edge part 23 of the said solar cell unit 2 between the head side edge parts 73. FIG. Next, the point of providing the spring part 74c and the tip part 74a is the same as that of the first embodiment, and the effect of the locking metal fitting 74 is substantially the same as that of the first embodiment. In addition, although the cushion material 8 of the bottom side edge part 23 of the solar cell unit 2 is provided here, this is not an essential requirement.
[0018]
Both locking bracket in each of these embodiments, bending stainless sheet width 10~20mm thickness 0.3 to 1.0 mm, intended to be manufactured in such鎔接, the solar battery unit 2 trailing edge While holding the locking function to the portion 23, the tip 74a is locked to the locking recess 11a while being urged by the elastic force of the spring portion 74c, so that the cover panel 7 is effectively prevented from being lifted. Therefore, it is possible to reliably prevent the solar cell unit 2 from floating and falling off during strong winds. Furthermore, since the shape of this locking metal fitting is not complicated, it is easy to manufacture. To attach it, it can be easily fitted by simply pressing it from above by bending the locking metal itself. There is an advantage that it is easy to handle.
[0019]
【The invention's effect】
Since the solar power generation roof tile of the present invention is configured as described above, it is possible to enhance the wind pressure resistance function so that the solar cell unit does not float up and fall off from the roof tile body even in strong winds such as typhoons. Therefore, it has an excellent effect of contributing to the popularization of photovoltaic power generation tiles as a safety enhancement. Therefore, the present invention has a very large industrial value as a photovoltaic power generation tile that has solved the conventional problems.
