The lateral positioning of each solar cell module (1) can be easily performed.

In the fixture (4), a positioning portion (not shown) is provided at a portion on which the ridge-side lateral frame member (11) and the vertical frame member (13) are mounted, and the positioning portion allows the solar cell module ( You may make it prevent the position shift of 1) in the horizontal direction.

A second ventilation gap (6) is provided between the standing plate portion (23) of the tool (2) and the connector insertion portion (111) of the ridge-side horizontal frame member (11). The ventilation path (24), the second ventilation hole (123), the first ventilation gap (5) and the second ventilation gap (6) form a ventilation path for communicating the outside with the back side of the solar cell module (1). It is a formed structure.

In the example of FIG. 7, as described in the fourth embodiment, the bent tip portion (122) of the stopper piece (122) is attached to the load receiving portion (112) on the rear surface of the connector insertion portion (111).
The eaves side horizontal frame member (12)
A gap is formed between the lower surface of the connector and the upper surface of the connector insertion portion (111), and a ventilation path is secured between the second ventilation gap (6) and the second ventilation hole (123). ing.

Thus, the solar cell module is sequentially passed from the outside through the first ventilation gap (5), the first ventilation hole (24), the second ventilation gap (6) and the second ventilation hole (123). By the ventilation path communicating with the back side of (1),

Will be discharged to the outside through the ventilation path. Therefore, effective ventilation is achieved,
The solar cell module (1) has an effect of preventing a decrease in energy conversion efficiency due to a high temperature, and also has an effect of preventing the roof base material (100) from being corroded or deteriorated because the back side space is in an environment with little humidity.

The second ventilation gap (6) is shielded from the outside by the standing plate (23) of the connector (2), and as illustrated in FIG. 8 (for the explanation of the positional relationship). 1) the first vent (24)
Since the left and right positions of the and second ventilation holes (123) are alternately shifted, rainwater from the outside does not leak to the back side of the solar cell module (1), and the ventilation path is waterproof. Has become.

With such a ventilation structure, ventilation and ventilation can be performed in the solar cell module (1) itself equipped with the frame structure of the invention of this application, and the ventilation is provided separately from the solar cell module (1). Since it is not necessary to use a ventilation member such as a module or a building with ventilation function, the appearance of the roof is not impaired and the number of installed solar cell modules (1) need not be reduced.

[Embodiment 7] Now, Embodiments 1 to 6 described above
In the invention of this application, the various structures in 1 are related to the lateral frame member of the solar cell module (1).
The following structure is also provided for the vertical frame member of the solar cell module (1).

That is, as illustrated in FIGS. 9 and 10, a supporting leg (7) is attached to at least one of the left and right vertical frame members (13) of the solar cell module (1). Roof base material (10)
0) The vertical frame member (13) is supported above.

With this support structure, it becomes possible to effectively prevent the deflection of the solar cell module (1) under the load from the vertical frame member (13). In addition, as illustrated in FIG. 9, for example, in order to prevent the displacement of the support leg (7), a protrusion (7) is formed on the upper surface of the support leg (7).
1) is provided, and a recess (131) is provided in the lower surface of the vertical frame member (13) so that the projection (71) and the recess (131) fit together.

[Embodiment 8] Further, as illustrated in FIG. 11, for example, the storage member (1) is located at the left and right ends of the module group on the roof, that is, as described later.
10) A solar cell module (1) adjacent to the solar cell module (1)
The vertical frame member (13) includes a vertical frame member (1
It is also a preferable aspect that the cover body (8) covering the adjacent end of the partition member (110) is detachably attached together with 3).

More specifically, in the example of FIG. 11, water leakage between the roof tile (120) laid around the solar cell module (1) and the vertical frame member (13) of the solar cell module (1). In order to prevent this, a partition member (110) which is a drainer made of sheet metal is provided. In this case, the cover body (8) covers the upper surface portion of the vertical frame member (13) and the standing plate portion (110a) of the partition member (110),
It is attached to the vertical frame member (13). Also,
The vertical frame member (13) is provided with a vertical gutter part (132) extending from the ridge side to the eaves side along the longitudinal direction thereof for flowing rainwater and the like toward the eaves, and the cover body (8). Is slidably fitted on the vertical gutter (132) in a detachable manner.

Then, from the cover body (8) to the partition member (110), the vertical frame member (13) and the roof tile (1)
While the waterproof structure with respect to 20) is realized, since the cover body (8) can be attached / detached to / from the storage member (110) independently, the storage member (110) is not removed. By simply removing the cover body (8), the solar cell module (1) can be easily and arbitrarily attached and detached.

In the example of FIG. 11, the roof tile (130) covering the cut surface of the roof tile (120) is fixed with the fixing screw (140).
Is fixed to the cover body (8) by screws. [Embodiment 9] When the solar cell module (1) is stepped on the roof with the above various structures, for example, as shown in FIG.
And a sheet metal cover body (200) as illustrated in FIG.
The ridge side of the solar cell module (1) can be housed by the or dummy module (210).

In the example of FIG. 12, a sheet metal fixing base (not shown), a joint base mounted and fixed on the sheet metal fixing base, and a sheet metal are attached to the ridge side end of the solar cell module (1) located on the most ridge side. A sheet metal cover body (200) is arranged via a jump base or the like installed so as to cover the fixed base and the joint base.

On the other hand, in the example of FIG. 13, a dummy module (210) is arranged as the final stage further on the ridge side of the solar cell module (1) located on the most ridge side. This dummy module (210) As the module, a module having substantially the same shape as the solar cell module (1) and capable of being cut at an arbitrary position is used. By cutting according to the dimensions up to the ridge (220) formed of ridge members and the like, module stepping that continues to the ridge (220) is realized.

According to the ridge-side storage structure using this dummy module (210), a unified design up to the ridge (220) can be obtained and a roof structure can be obtained, as compared with the case where the sheet metal cover body (200) is used. It is possible to realize a better appearance, such as an improved sense of unity. In addition, the number of parts such as the projected corner that require separate treatment is reduced, which leads to a reduction in the total construction time.

Furthermore, when the sheet metal cover body (200) is used, it is necessary to lay a roof tile between the sheet metal cover body (200) and the ridge (220), and in that case, the solar cell module is naturally used. Roof tiles (1) laid around (100)
Although it is preferable to use the same thing as 20), depending on the space etc., roof tiles (120) of a type that is impossible or difficult to lay may be generated, and roof tiles (120) may not fit together. Dummy module (21
In 0), the solar cell module (1) and the ridge (220)
It is not necessary to lay a roof tile (120) between
No restrictions are imposed on the type of 0).

Further, since the sheet metal cover body (200) is normally not allowed to adjust the dimension in the flow length direction, unless there is a sufficient space between the sheet metal cover body (200) and the ridge (220). , Sheet metal cover body (200) and roof tile (1
There may be situations where even 20) cannot be installed. Even in this case, it is necessary to store the solar cell module (1) on the ridge side, so it is conceivable to reduce the solar cell module (1) by one step, but this will not achieve the desired mounting amount of the solar cell module (1). Will end up. On the other hand, if the dummy module (210) is used, the ridge-side storage can be realized by adjusting the cutting even in a small space, and the installation rate of the solar cell module (1) can be improved.

As described above, when laying the dummy module (210) which realizes excellent storage on the ridge side, the frame structure used for the solar cell module (1) described above can be applied as it is.

FIG. 14 and FIG. 15 show an example thereof, in which the eaves side horizontal frame member (12) is attached to the eaves side end of the dummy module (210), and the eaves side horizontal frame member (12) is attached. Are connected to the ridge-side horizontal frame member (11) of the solar cell module (1) on the outermost ridge side via the connecting tool (2) in a separable manner as described above.
After that, the ridge side end of the dummy module (210) is supported on the roof base material (100) by the support material (230),
A ventilation ridge member (25
0) etc. may be installed. As a result, not only is the external shape substantially the same as that of the solar cell module (1), but the eave-side lateral frame member (12) same as that of the solar cell module (1) can be used for laying the solar cell module (1). Module steps including the dummy module (210) can be performed in the construction procedure.

The dummy module (210) is made parallel to the surface of the solar cell module (1) by adjusting the height of the support member (230) (FIG. 14).
(See FIG. 15) or in parallel with the roof base material (100) such as a field board (see FIG. 15). As a result, in the sheet metal cover body (200), the inclination of the surface may become gentler than that of the roof surface and snow may be easily accumulated, whereas the inclination of the dummy module (210) does not become gentler than the roof surface. Therefore, concentrated snow accumulation does not occur, and application to snowy areas becomes easy. Also,
When the roof base material (100) is parallel to the roof base material (100), it is not affected by the flow length of the dummy module (210), and the cap sheet (240) or the building sheet metal (260) provided on the opposite side of the building.
It becomes possible to use etc. as a common member.

Of course, the present invention is not limited to the above examples, and various details can be made.
