BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar heat collector installation structure and can be used in a building such as a house equipped with a solar system.

[0002]

BACKGROUND ART Solar energy has conventionally been known as energy that does not adversely affect the environment and ecosystems, and solar cells such as solar cells and solar heat collectors that convert this solar energy into electricity and hot water can be used. There is an energy conversion device. Such a device is generally installed on the roof of a house or the like. Among them, the solar heat collector needs to prevent its components such as the heat ray absorbing plate and the heat transfer pipe from being directly exposed to the weather. is there. For this reason, the solar heat collector is housed inside a waterproof box and installed on the roof, or the solar heat collector is roofed by opening an opening in which a transparent plate is inserted into a roof plate that forms the structural surface of the roof. In-roof built-in method, etc.
A structure is adopted in which the solar heat collector is installed in a sealed state.

[0003]

However, in the box method, since the waterproof box projects from the upper surface of the roof and the pipes connected to the solar heat collector are exposed to the outside, the appearance of the building is impaired. There's a problem. On the other hand, the method with a built-in roof can solve the design problem. However, the built-in roof method requires a waterproof treatment using a wet sealant in order to close the gap between the structural surface of the roof and the transparent plate, so this waterproof treatment is time-consuming and complicated. There is a problem above. Moreover, with this built-in roof method, if the solar heat collector fails, repairing inside the roof requires working in a narrow space, and repairing outside the roof requires a transparent plate. Since it has to be removed, it is necessary to perform a complicated waterproofing process again, and in any case, there is a maintenance problem that maintenance work becomes difficult.

It is an object of the present invention to provide a solar heat collector installation structure that does not impair the appearance of the building and is easy to install and maintain.

[0005]

The present invention provides a solar heat collector installation structure for installing on a roof a solar heat collector that absorbs radiant heat of the sun and heats a heat medium that is circulated inside. A pair of rail-shaped support members are laid on the structural surface so as to be parallel to each other, a solar heat collector is arranged between these support members, and a transparent panel covering the solar heat collector is laid over the pair of support members. It is characterized by being installed.

In the above, it is preferable that each of the support members is laid along the inclination direction of the sloping roof. Further, as the support member, a trough portion having a U-shaped cross section having an opening at the upper side and the trough portion. It is possible to employ a pipe part having a quadrangular cross section that is integrally provided below the pipe.

[0007]

In the present invention as described above, since the solar heat collector is arranged on the structural surface and the solar heat collector is covered with the transparent panel to ensure the waterproof performance, it is not necessary to open an opening on the structural surface of the roof. . For this reason, a wet sealant is not required, and the transparent panel can be easily attached and detached by screwing the transparent panel to the support member or the like, which facilitates construction and maintenance. Further, if a roofing material that forms the surface of the roof is pasted through the supporting member or another spacing member, the roofing material and the transparent panel can be arranged on the same surface and protrude from the roof surface. In addition, since the pipe can be provided inside the transparent panel, the pipe and the like are not exposed, and the appearance of the building is improved, thereby achieving the above object.
