Description

Detailed Description of the Invention

[0001]

The present invention relates to, for example, snow melting, snowfall roofs,
The present invention relates to a water-repellent roof, a solar system, a roof base material effective for roof ventilation, and a roof structure including the same.

[0002]

2. Description of the Related Art Generally, as a roof structure of a building, for example, a plurality of base plates are arranged in parallel on a rafter tree, a waterproof material is put on the base plates, and a metal roof member such as a copper plate or a zinc iron plate is placed on the roof plate. In addition to light alloy plates, there are known flat plate roofs, single-character roofs, roof bar roofs, corrugated roof structures and tile roof structures that use various chemically treated steel plates.

In recent years, various roof structures having a snow melting function and a solar system function have been proposed in snowy areas.

As such a roof structure, for example, a urethane heat insulating material is placed on the above-mentioned base plate, a pipe is arranged in a concave groove portion of this heat insulating material, and an aluminum heat radiating plate is placed on the heat insulating material. However, it is constructed by laying the roofing material on the heat sink, and at the time of snowfall in the winter, hot water or antifreeze is passed through the pipe to transfer the heat of the hot water or antifreeze to the heat sink, The heat conducted to the roofing material is transmitted to the roofing material, and the snow on the top surface of the roofing material is melted by radiating heat from the top surface of the roofing material. Is heated by solar heat, and the heat of this hot water is exchanged by a heat exchanger to be used for hot water supply or the like.

[0005]

However, in the case of the above-mentioned conventional structure, when the number of the tubes is reduced, the temperature distribution of the heat from the hot water and the antifreeze during the snow melting is concentrated in the upper part of the passing tube, and the snow melting only near the tube. It is easy to cause a cavitation phenomenon due to the snowfall to reduce the snow melting efficiency, and the cavitation phenomenon tends to increase the running cost, and in the case of a water-sprinkling type roof, dew condensation may occur between the back surface of the roof material and the base plate or waterproof material. However, any roof structure may cause rain leaks, leaks, and roof defects, and when used as a solar system, the heat collection efficiency will be low and the construction and maintenance will be the same as in the case of snow melting. However, there is a problem that water leakage and rain leakage easily occur from the joint portion of the pipes.

[0006]

The base material and the roofing material, in which a mounting portion capable of mounting the roofing material on the base material is partially formed in a raised state, and the roofing material is mounted on the mounting portion. A flow passage through which a heat exchange medium such as air or liquid can pass, and the flow passage is formed such that the heat exchange medium passes continuously or intermittently while moving laterally. It is in a roof base material and a roof structure including the same.
