Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure for attaching a so-called roof-integrated solar heat collector to a roof, in which the solar heat collector also serves as a roof plate and is supported by a roof base.

The present inventor first proposed a structure for attaching a roof-integrated solar heat collector to a roof, which can ensure sufficient mounting strength and watertightness. A solar heat collector is supported on the support frame by fixing a support frame for the solar heat collector, and providing a flashing board that extends to the roof to cover the outer surface of the support frame. A structure in which the attached hanging plate is located outside the support frame was developed and applied for (Japanese Patent Application No. 56-203046,
56−203047).

The first invention of the present application further improves the mounting structure proposed earlier, and maintains sufficient watertightness even when a heat collecting medium such as water or rainwater leaks from the heat collector due to failure of the heat collector. The purpose is to provide a structure for attaching the heat collector to the roof, and its features are as follows.
The upper surface of the frame opening of the heat collector support frame is closed with a waterproof cover plate.

The second invention of the present application, in addition to the object of the first invention,
