Description

[0001]
BACKGROUND OF THE INVENTION
INDUSTRIAL APPLICABILITY The present invention can be used, for example, in a ridge structure with a gradient roof provided with a solar cell panel that converts sunlight into electric power.
[0002]
[Background]
Conventionally, on a sloped roof such as a gable or a dormitory, a ridge structure is provided to cover a joint portion (hereinafter referred to as a ridge portion) between adjacent roof surfaces. In general, a wing member is formed by bending a material having a predetermined width at a substantially central position, and extends toward the roof surface from the ridge member main body disposed along the ridge portion. And legs. Such a ridged object has its ridges (folded portions) provided on the boundary between the roof bases.
[0003]
On the other hand, in recent years, there is solar energy as clean energy that does not adversely affect the environment and ecosystem. As a method of using solar energy at home, there is a roof with a solar cell in which a solar cell for converting solar energy into electric energy is installed on a roof surface.
Solar cells installed on roofs with solar cells need to prevent breakdowns such as leakage and short circuit due to ingress of moisture, so they are housed in a flat, completely waterproof case with a predetermined thickness. (Japanese Patent Laid-Open No. 2000-110310).
[0004]
[Problems to be solved by the invention]
By the way, when a solar cell panel is installed only on one of the sloped roof surfaces, for example, the south surface, the height from the roof base material of the roof surface on which the solar cell panel is installed to the surface of the solar cell panel and the solar cell panel are not installed. The height from the roof base material of the roof surface to the roof finishing material surface is different.
Therefore, if the ridge part is to be mounted on the boundary between the roof bases, the roof finishing material from the roof base material on both roof surfaces is different, so the roof on which the solar panel is installed. The difference between the height of the leg portion on the surface side and the height of the leg portion on the roof surface side where the solar cell panel is not installed may increase, resulting in a poor appearance.
[0005]
An object of the present invention is to provide a ridge structure of a sloped roof that can satisfactorily fit the appearance even if it is a sloped roof having a roof surface with a different height from the roof base material. .
[0006]

[0008]
In addition , since the roof surface with the lower height to the finishing material surface is extended to the roof surface with the higher height to the finishing material surface, the length in the width direction of the building main body can be adjusted freely. .
[0009]
The ridge structure of the sloped roof according to claim 2 is characterized in that, in the ridge structure of the sloped roof according to claim 1, the leg portion extends substantially vertically from the wing accessory main body.
According to this invention, since the leg portion is extended substantially vertically from the building body, the drainage of the leg surface can be improved and the adhesion of dust can be suppressed, so that waterproofness and durability can be improved. .
[0010]
The ridge structure of the sloped roof according to claim 3 is the ridge structure of the sloped roof according to claim 1 or 2 , wherein the length from the ridge part of the wing accessory main body to each of the leg parts is substantially equal. It is characterized by that.
According to this invention, since the length from the ridge part to each leg part of the building accessory main body is made substantially equal, the appearance of the building accessory can be improved in plan view.
[0011]
The ridge structure of the gradient roof according to claim 4 is the ridge structure of the gradient roof according to any one of claims 1 to 3 , wherein a roof surface having a higher height from the roof surface to the surface of the finishing material is selected. The finishing material to be formed is a solar cell panel.
According to the present invention, since the finishing material constituting the roof surface having a higher height to the surface of the finishing material is the solar cell panel, the solar energy is converted into the electric energy while suppressing the temperature rise of the roof surface due to solar heat. It can be effectively used by converting to, and energy saving can be achieved.
