Description

  The present invention relates to a photovoltaic roof and a mount. More specifically, the present invention relates to a single-flow solar roof and a gantry used therefor.

  Conventionally, a photovoltaic power generation roof in which a roof of a building and a photovoltaic power generation panel are integrally formed is known (see, for example, Patent Document 1). As for the solar power generation panel, the power generation efficiency decreases as the temperature rises. Therefore, in a photovoltaic roof, generally, a photovoltaic panel is arranged separately from a base material of a building. Thereby, an air passage is formed between the photovoltaic power generation panel and the base material of the building, and the air flows through the air passage, thereby suppressing the temperature rise of the photovoltaic power generation panel.

  By the way, although it is not a solar power roof, as a structure for ventilation inside the single-flow roof, along with the eaves-side vents, the ridge-side vents that are formed in the upper part of the decorative material arranged on the wing side and open to the eaves side There is known a roof formed with a ventilation passage having, for example, Patent Document 2.

JP 2013-76304 A Japanese Patent No. 3280657

  However, when the structure for ventilation of the roof described in Patent Document 2 is applied to a photovoltaic power generation roof, a step is generated between the surface of the photovoltaic power generation panel and the surface of the wing decorative material, The design of the appearance deteriorates. In addition, since both the eaves-side vent and the ridge-side vent that the vent has are open toward the eave, the wind blown from the ridge is not blown into the vent, but the The air blown into the air passage from the side vent is pushed back by the wind blown from the same eaves side at the wing side vent. Therefore, the air permeability of the air passage having such a structure is not fully satisfactory.

  It is an object of the present invention to provide a photovoltaic power roof capable of sufficiently increasing the air permeability of the air passage and improving the design, and a mount used for the roof.

  In order to achieve the above object, the present invention is a solar power roof (for example, a solar power roof 1 described later), and a frame (for example, a solar panel frame 4 described later) arranged from the building to the eaves. And a solar power generation panel (for example, a solar power generation panel 5 described later) that is disposed apart from the base material (for example, a base material 3 described later) and is fixed on the base. Are a gantry main body (for example, a gantry main body 40 described later) fixed to the base material, and a wing decorative material (for example, a wing side frame member 62 described later) disposed so as to cover the ridge side end of the gantry main body. ), And between the solar power generation panel and the base material, an eaves-side vent opening (e.g., eave-side vent 71 described later) and a ridge side opening to the ridge side are provided. A ventilation path (for example, a ridge side ventilation hole 72 described later), and a ventilation path (for example, The above-described ventilation path 7) is formed, and the wing decorative material communicates with the ventilation path via the ridge-side ventilation hole and is disposed on the opposite side of the ridge-side ventilation hole via the ridge. Provided is a photovoltaic roof that forms an exhaust passage (for example, an exhaust passage 8 described later) having an exhaust port (for example, an exhaust port 81 described later).

  Thereby, the air blown into the ventilation path from the eaves-side vent by the wind blown from the eaves side passes through the ventilation path and the exhaust path to the building side. On the contrary, the air blown into the exhaust passage from the exhaust port by the wind blown from the building side passes through the exhaust passage and the vent passage to the eave side from the eave side vent. Thus, the solar power roof has sufficiently high air permeability because the eaves-side vent and the exhaust passage are opened in opposite directions. Furthermore, since the roof on the photovoltaic power generation roof is not formed on the upper side of the ridge-side frame material, it is necessary to increase the level difference between the surface of the photovoltaic power generation panel and the surface of the ridge-side frame material. Therefore, it is possible to improve the design.

  In addition, the solar power roof is a single-flow type, and is erected on the ridge-side end of the single-flow roof in the exhaust path, and communicates with the vent path (for example, a vent-path-side exhaust described later). Path 82S), an exhaust port side exhaust path (for example, an exhaust port side exhaust path 83S described later) that communicates with the exhaust port, and a communication path (for example, a later described communication path 84S) that communicates these exhaust paths. It is preferable to further include a water return material (for example, a water return material 9S described later).

  In addition, the present invention provides a photovoltaic roof (for example, described later) provided with a photovoltaic panel (for example, a later-described solar panel mount 4) arranged separately from a foundation material (for example, a later-described foundation material 3). In the solar power generation panel 5), the solar power generation panel 5 is a gantry (for example, a solar panel gantry 4 described later) that is arranged from the ridge to the eaves and fixes the solar power generation panel, and is fixed to the base material. A gantry body (for example, a gantry body 40 to be described later) and a wing decorative material (for example, a wing side frame member 62 to be described later) disposed so as to cover an end of the gantry body on the ward side. Is an eaves side vent opening (e.g., eaves side vent 71 described later) between the solar power generation panel and the base material, and a ridge side vent opening (e.g. An air passage (for example, a wing side air vent 72) to be described later (for example, The above-described ventilation passage 7) is formed, and the wing decorative material communicates with the ventilation passage through the ridge-side vent and is disposed on the opposite side to the ridge-side vent through the ridge. A gantry for forming an exhaust path (for example, an exhaust path 8 described later) having an exhaust port (for example, an exhaust path 81 described later) is provided.

  According to the present invention, it is possible to provide a photovoltaic power roof capable of sufficiently increasing the air permeability of the air passage and improving the design, and a mount used for the roof.

Next, the ventilation path 7 between the photovoltaic power generation panel 5 and the base material 3 will be described in detail.
As shown in FIG. 4, the air passage 7 includes an eaves-side vent 71 that opens to the eaves side, and a ridge-side vent 72 that opens to the ridge side. Further, the ridge-side frame member 62 (the ridge cover 621) communicates with the ventilation path 7 via the ridge-side vent 72, and the exhaust port 81 disposed on the opposite side of the ridge-side vent 72 via the ridge. An exhaust path 8 having The exhaust port 81 opens downward on the ridge side.

  For example, air that has flowed into the ventilation path 7 from the eaves-side vent 71 passes through the ridge-side vent 72. As the air flows through the air passage 7, the photovoltaic power generation panel 5 is cooled from the back side. Then, the air that has passed through the building side vent 72 passes through the exhaust passage 8 and is discharged from the exhaust port 81. Air flowing into the exhaust path 8 from the exhaust port 81 flows in the reverse direction.

According to the solar power roof 1 according to the first embodiment, the following effects are produced.
In 1st Embodiment, in the photovoltaic roof 1 in which the ventilating path 7 which has the eaves side ventilation hole 71 opened on the eaves side, and the ridge side ventilation hole 72 opened on the ridge side was formed, the ridge side frame material 62 communicates with the ventilation path 7 via the ridge-side vent 72 and forms an exhaust path 8 having an exhaust port 81 disposed on the opposite side of the ridge-side vent 72 via the ridge. .
Thereby, the air blown into the ventilation path 7 from the eaves-side vent 71 by the wind blown from the eaves side passes through the ventilation path 7 and the exhaust path 8 and escapes from the exhaust port 81 to the ridge side. On the other hand, the air blown into the exhaust path 8 from the exhaust port 81 by the wind blown from the building side passes through the exhaust path 8 and the vent path 7 from the eave side vent hole 71 to the eave side. Thus, the solar power roof 1 has sufficiently high air permeability because the eaves-side vent 71 and the exhaust passage 8 are opened in opposite directions. Further, since the solar roof 1 is not formed on the ridge side frame 62 with the ridge side vent, a step between the surface of the photovoltaic panel 5 and the ridge side frame 62 is provided. Since it is not necessary to increase the size, it is possible to improve the design.

  Moreover, according to the solar panel mount 4 used for the solar power roof 1 in this embodiment, the same effect as the solar power roof 1 can be obtained.

Second Embodiment
Subsequently, a photovoltaic roof 1S according to a second embodiment of the present invention will be described.
In addition, about the photovoltaic roof 1S which concerns on 2nd Embodiment, the structure different from the photovoltaic roof 1 which concerns on 1st Embodiment is demonstrated, and description is abbreviate | omitted about the same structure.

FIG. 5 is an enlarged view of the ridge side in the longitudinal sectional view of the solar power roof 1S.
As shown in FIG. 5, the photovoltaic power generation roof 1 </ b> S further includes a water return member 9 </ b> S that is erected on the ridge side end of the single-flow roof in the exhaust path 8 </ b> S. The water return material 9S partitions the exhaust passage 8S into an air passage side exhaust passage 82S that communicates with the air passage 7S, an exhaust port side exhaust passage 83S that communicates with the exhaust port 81S, and a communication passage 84S that communicates these. The ridge cover 621S has a bent portion 624S that is bent from the eave side of the upper surface portion and extends downward. The bent portion 624S has a groove 625S formed by further bending the tip to the inside of the wing decorative material. The groove 625S is formed on the ridge side of the eaves-side end at the top of the water return material 9S. Even if rainwater blows into the exhaust path 8S from the exhaust port 81S and adheres to the tip of the water return member 9S and drops on the inner surface of the bent portion 624S by such an arrangement, the rainwater is accumulated in the groove 625S. The water collected in the groove 625S flows into the vertical rail 41 and is drained to the eaves side.

According to the photovoltaic roof 1S according to the second embodiment, in addition to the effects exhibited by the photovoltaic roof 1 according to the first embodiment, the following effects are exhibited.
In the second embodiment, there is provided a water return material that stands on the ridge side end of the single-flow roof and partitions the exhaust passage into a ventilation passage-side exhaust passage, an exhaust outlet-side exhaust passage, and a communication passage that connects these. .
Thereby, even if rainwater blows into the exhaust path 8S from the exhaust port 81S, rainwater can be prevented from entering the ventilation path 7S.

It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
In the first and second embodiments, the ridge cover 621 is screwed directly to the ridge attachment 622, but the present invention is not limited to this. For example, as shown in FIG. 6, the ridge-side frame member 62 may further include one or more adjustment members 624, and the ridge cover 621 may be connected to the ridge attachment 622 via the adjustment member 624. . Generally, the size of the photovoltaic power generation panel 5 is set to a specific size according to the standard for each product. On the other hand, the size of the roof varies by individual building and is not constant. Therefore, the distance of the gap between the photovoltaic power generation panel 5 and the surrounding frame is not constant. However, if the adjusting material 624 is disposed between the photovoltaic power generation panel 5 and the building side frame material 62 and the number and size of the adjusting materials 624 are further adjusted, the designability and the air permeability of the air passage 7 are impaired. And the gap between the adjusting material 624 and the surrounding frame can be filled.

  Moreover, in the said 1st and 2nd embodiment, although the single flow type photovoltaic power generation roof 1 and 1S were demonstrated, this invention is not limited to a single flow type roof, It is also possible to apply to a gable type roof. It is.
