DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain roof structure of a solar cell roof between a solar cell roof constituted by a plurality of solar cell modules and a normal roof located on the eaves side.

[0002]

2. Description of the Related Art As a conventional rain-closing structure for a solar cell roof of this type, for example, a structure described in Japanese Patent Application Laid-Open No. 7-150718 is known. This solar cell roof has a plurality of vertical members fixed on a normal roof such as a slate roof or a tiled roof, and a plurality of solar cell modules are laid so as to be supported by the vertical members. On the side end,
A decorative cover is attached so as to be supported on the vertical member via a support fitting. The upper part of the decorative cover forms a roof surface contiguous with the upper surface of the solar cell module, and the lower part hangs down to cover the edge of the vertical member. A large number of ventilation holes are formed in the lower half of the decorative cover, so that the lower space of the solar cell module composed of the vertical members can be ventilated.

[0003]

In such a conventional solar cell roof, since a solar cell module is laid on a normal roof via a vertical member, a high waterproof performance is required for the solar cell roof itself. However, in the case of solar cell roofs that use solar cell modules as roofing materials, high waterproof performance is required for the solar cell roof itself, and high waterproofing is possible even in the event of rain between the roof and the ordinary roof located on the eaves side. Performance is required. In such a case, simply applying the above-mentioned conventional solar cell roof, for example, rainwater blows from the ventilation holes of the decorative cover, causing a problem such as water leakage on the roofing base. Insufficient ventilation of the lower space causes problems such as a decrease in the power generation efficiency of the solar cell module.

[0004] It is an object of the present invention to provide a rain break structure for a solar cell roof that can improve the waterproof performance and the ventilation performance at the eaves end of the solar cell roof using a solar cell module as a roofing material. And

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a solar cell roof with a rain roof structure comprising a plurality of solar cell modules as roofing members, which are formed on a common roofing base. In the rain-covered structure of the solar cell roof between the ordinary roof located on the eaves side, a covering member that covers the eaves-side end of the solar cell roof and guides rainwater from the solar cell roof to the ordinary roof, While being covered with
A ventilation member that closes the eaves-side ventilation opening of the ventilation space formed below the plurality of solar cell modules so that the ventilation and the water can be stopped; and the ventilation member includes a number of ventilation holes that communicate the outside of the roof and the ventilation space. It is characterized by being constituted by a continuous porous body having a passage.

According to this configuration, the rainwater flowing down the solar cell roof is smoothly guided from the roof surface of the solar cell roof to the roof surface of the ordinary roof by the covering member that covers the eave-side end of the solar cell roof. I will Also, as it is covered by the covering member,
Because the eaves side ventilation opening connected to the ventilation space of the solar cell module is equipped with a ventilation member that can vent and stop water,
Through this ventilation member, the ventilation space can be well ventilated. In this case, since the ventilation member is formed of a continuous porous body having a large number of ventilation passages, it allows the inflow of outside air through the ventilation passages, while suppressing the inflow of rainwater by the passage resistance. This allows the ventilation air to flow into the attic of the solar cell roof, and prevents rainwater and small animals from entering. In addition, it is preferable that each ventilation passage has a substantially tapered shape in which the side facing the outside has a large diameter and the side facing the ventilation space has a small diameter.

[0007] In this case, it is preferable that the ventilation member is arranged such that the direction of extension of the plurality of ventilation passages is along the roof slope.

[0008] According to this configuration, the ventilation member further suppresses the inflow of rainwater in a state where the inflow of outside air is allowed by the inclination of the roof in addition to the passage resistance of the ventilation passage.
In addition, the ventilation member smoothly drains water leakage and dew condensation generated on the attic of the solar cell roof to the roof side through the ventilation passage.

In these cases, the ventilation member is preferably sandwiched between a lower base material provided on the roofing base and an upper base material provided inside the covering member.

[0010] According to this configuration, the covering member can be appropriately supported by the upper base material, and the thickness of the lower base material is adjusted to the thickness of the roofing material of the ordinary roof.
The height position of the ventilation member can be adjusted to an appropriate position for various roofing materials.

In these cases, it is preferable that a drain plate is provided at least from the upper surface of the lower base material to the upper surface of the roofing material of a normal roof.

According to this configuration, even if rainwater enters from the lower surface of the ventilation member or the like due to a strong wind or the like, it is possible to prevent the rainwater entered by the drain plate from leaking onto the roofing base. In addition, if the ridge side end of the drain plate reaches the structural material such as the vertical frame, it is possible to appropriately guide the condensed water discharged through the structural material to the ordinary roof.

[0013] In this case, it is preferable that a water return portion is formed by bending at a ridge side end of the drainer plate.

According to this configuration, even if the rainwater that has flowed backward and enters the spill reaches the ridge side end of the drain plate, the backflow is prevented by the water return portion. Leakage to the ground can be reliably prevented.

According to these constructions, the seal member may be interposed between the eaves-side end of the lower base material and the roofing material of the ordinary roof, located below the drain plate. ,preferable.

According to this configuration, even if rainwater enters the roofing material from below the drain plate on the ordinary roof, the water is stopped by the seal member on the upstream side thereof, so that the roofing material of the ordinary roof can be removed. Rainwater can be prevented from leaking.

As described above, according to the solar cell roof rain closing structure of the present invention, the ventilation member connected to the ventilation space of the solar cell module is constituted by a continuous porous body having a large number of ventilation passages. In addition, while inflow of outside air is allowed through the ventilation passage, inflow of rainwater can be suppressed by resistance of the passage. For this reason, while being able to ventilate the attic of a solar cell roof satisfactorily, invasion of rainwater and small animals into the attic can be effectively prevented. Therefore, without impairing the waterproofness between the ordinary roof,
Waterproofness and drainage at the eaves-side end of the solar cell roof, and ventilation of the attic can be improved.
