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]

SUMMARY OF THE INVENTION An object of the present invention is to solve these problems. The gist of the present invention is to mount a base material on a roof constituent member of a building and to which a roof material can be mounted and fixed. The base material is a cement-based panel material, and the base material is formed by forming a plurality of passages that are continuous with the attic space of the building and that allow heat exchange through the roof material. And the roof structure provided with the same.

[0007]

[Function] A base material made of a cement-based panel material is placed on a roof constituent member of a building, and the roof material is placed on the base material,
Connect the attic space of the building to the passage formed in the base material,
Through the passages, the entire surface of the roofing material will perform heat exchange.

Reference numeral 2 is a roof material, which has a metal sheet roof structure in this case.

Reference numeral 3 is a base material, which is made of cement-based panel material or the like, and a plurality of concave groove-shaped passages 4 are formed on the upper surface of the base material 3, and in this case, the lower surface of the base material 3 is also recessed. A plurality of grooved channels 5 are formed.

Reference numeral 6 denotes a roof constituent member of the building 1, in this case a ground plate, which is arranged on the rafters 7 arranged in parallel.

Reference numeral 8 denotes a ceiling material. In this case, the attic space R above the ceiling material 8 has a highly airtight and highly heat-insulating structure, and the ceiling material 8 is formed with a vent hole 9 for communicating the attic space R with the room M.
An intake port 11 is formed on the wall of the building 1 to connect the room M to the outside.

Reference numeral 12 denotes a fan as an intake / exhaust means, which is arranged above the attic space R and sends the air in the attic space R into the passage 4 of the base material 3 by the air a.

A heat exchanger 13 is disposed in the attic space R, has an air suction pipe 14 connected to one opening of the passage 4 of the base material 2, and the heat exchanger 13 has a hot water supply pipe connected to the boiler 15. 16 are connected.

Since the first embodiment has the above-mentioned structure, as shown in FIG. 1, the roof boards as the roof constituting members 6 are mounted in parallel on the barrel 7 in this case, and the waterproof material 1 is mounted on the roof boards.
7 is laid, the base material 3 is attached on the waterproof material 17, and the metal roof material 2 is laid on the base material 3 to construct a roof structure.

However, at the time of snow melting, as shown in FIG.
The air warmed by the heating device N etc. in the room M is vented 9
And the like into the attic space R, and the attic space R is in a warm state, and this warm air is sent to a plurality of passages 4 of the base material 3 by a fan as the intake / exhaust means 12, and the passage 4 The warm air inside passes through and is released to the outside from, for example, the eaves portion, and the heat of the warm air exchanges heat with the snow S through the roof material 2 at the time of this passage, so that the snow melting action is performed. become.

When using solar heat, as shown in FIG. 4, the air in the plurality of passages 4 of the base material 3 is heated by the solar heat through the roof material 2, and the heated air is sucked by the air suction pipe 14. Enters the heat exchanger 13 and the heat exchanger 1

The roof structure is suitable for snow melting, snowfall roof, water sprinkling type roof structure and roof ventilation, and a roof structure with high versatility in living comfort can be obtained and nailing is possible because of cement panel material. Therefore, roof construction becomes easier.

At this time, the air in the room M enters the attic space R through the ventilation holes 9 of the ceiling material 8 and the like, and when the snow melts, the base material 3 is used.
Is discharged to the outside through the passage 4 of the above, and when using solar heat, an outside air port or an air suction pipe 14 not shown formed on the outer wall of the attic or the like.
Since the air is exhausted to the outside through the passage 4 of the base material 3 which is not connected to the above, the ventilation effect of the room M can be obtained.

The concave groove 5 on the lower surface of the base material 3 serves as a ventilation effect between the waterproof material 17 and the base material 3.

The second embodiment of FIG. 5 shows another structure. In this case, the pipes 18 are internally provided in the passages 4 of the base material 3 at predetermined intervals to obtain the same effect as that of the first embodiment. At the time of snow melting, warm water or the like is forced to warm the air in the passage 4 when the snow is melted, and when the solar heat is used, water is passed through the pipe 18 to heat the water. The pipe 18 may be a heat pipe.

The third embodiment of FIG. 6 shows another structure, in which the passages 4 and the grooves 5 of the base material 3 are formed into a mountain shape and a wave shape.
