Description

[Detailed description of the invention] [Industrial application field] The present invention relates to improvement of a roof structure, and particularly to a technique for efficiently and efficiently melting snow on a roof in a snowy area.

[Conventional technology]

As is well known, the roof structure of a building such as a prefabricated house is one in which a roof frame (main building) is fixed above a beam and a roofing material such as a color vest or a tile is laid above the roof frame. As the configuration of the intervening member interposed between the roofing material and the roof frame, for example, the following one has been put to practical use.

That is, a field board is fixed directly above the roof frame (main building), a waterproof asphalt roofing is pasted directly above the roof board, and a heat insulating material is further covered immediately above the roofing frame. A roofing material is laid directly above the building. Then, the roofing material is fixed by driving a nail or the like into the field board from above the roofing material.

On the other hand, in recent years, a long continuous formed plate material corresponding to the size of a plurality of ordinary tiles has been used as a roofing material, but this continuous formed plate material is usually formed by forming a steel sheet. It is obtained.

[Problems to be solved by the invention]

By the way, in the above-mentioned conventional roof structure, although the heat insulating material is arranged directly below the roofing material, only the method of using the heat insulating material in this manner merely obtains the heat retaining effect, and the positive effect is obtained. The heating action cannot, of course, be performed. For this reason, in a snowy area, a large amount of snow remains on the roof, and various troubles are caused unless troublesome and complicated snow removal work such as snow removal is performed.

Then, when the continuously formed plate material of the above example is used as a roofing material, there is a problem as to what measures should be optimally taken in order to eliminate snow on the roof reliably and efficiently.

The present invention has been made in view of the above circumstances, and by adding a new structure suitable for a roof structure, it is possible to optimally reduce snow cover on a roof when a continuously formed plate is used as a roofing material. The technical task is to make sure that it is possible to deal with it.

[Means for solving the problem]

A specific means for achieving the above technical problem is that in a roof structure using a long continuous formed plate material as a roofing material at least in a direction from the eaves part toward the ridge, the continuous formed plate material The heating element extending in a substantially horizontal direction is disposed below.

In this case, it is preferable to dispose the heating element more densely in the eaves part than in the ridge part.

[Action]

According to the above-described means, as a basic configuration, asphalt roofing or heat insulating material above the base plate at least in the direction from the eaves part toward the ridge, and more specifically, the asphalt roofing or heat insulating material and the continuous formed plate material A heating element extending in a substantially horizontal direction (a direction orthogonal to the direction from the eaves tip toward the ridge) is arranged between the heating element and the heating element. As a result, snow melting on the roof becomes possible, and the harmful effects of snow on the buildings in the heavy snow area are reduced as much as possible. In this case, the continuously formed plate is long in the direction from the eaves to the ridge, and the heating element is disposed so as to extend in a direction perpendicular to the eaves. The applied heat is surely conducted in the direction from the eaves to the ridge, so that suitable heat conduction is performed to the entire roof.

In addition, as an additional configuration, the heating elements are arranged closer to the eaves than the ridges, in other words, the heating elements are concentrated and arranged at the eaves. Or the air heated intensively by the action of the heating element at the eaves side of the continuous space existing between the heat insulating material and the continuously formed plate material floats up the continuous space toward the ridge side. Therefore, the continuously formed plate material is surely heated even on the ridge side, and the snow melting on the roof is performed efficiently and economically.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

First, a schematic configuration of a snow-melting roof structure according to the present invention will be described with reference to FIG. 1. In a roof 1 of the building, a plurality of continuously formed plate members 2... 2 are used as a roofing material. 2 are made of steel plate, and the size of one continuous formed plate 2 is a large number of tiles of a normal size in a direction (vertical direction) from the eaves to the ridge. The direction (lateral direction) in which the tiles are arranged and perpendicular to this corresponds to the size in which a small number of tiles of normal size are arranged, and is obtained by molding into a predetermined shape by molding or the like. Under these continuous formed plate members 2,..., Heating elements 3,... Formed by heating wires extending in a substantially horizontal direction (lateral direction) are arranged. The eaves are denser than the ridge. In other words, the heating elements 3... 3 are arranged in a concentrated manner at the tip of the eaves.

The above-mentioned roof structure will be described in more detail. As shown in FIG. 2, a roof frame (main building) 5 fixed to the climbing beam 4 is provided.
5, a field board 6 is fixedly mounted, and a heat insulating material 8 is attached above the field board 6 via an asphalt roofing 7, and the above-described continuous formed plate 2 is provided above the heat insulating material 8. 2 are laid, and a fixing member such as a nail is driven into the base plate 6 from above the continuous formed plate members 2 in this state, so that each of the constituent members is connected to the base plate 6 and the roof frame 5. 5 and thus firmly fastened to the climbing beam 4. In such a state, the heating elements 3... 3 are arranged in the gap between the continuously formed plate members 2.

In this case, as is clear from FIG. 3, a continuous space A... A communicating from the eaves to the ridge is formed between the continuous molded plate 2 and the heat insulating material 8.

In this embodiment (see FIG. 1), as described above, under the condition that the heating elements 3... 3 are arranged below the continuously formed plate members 2. 3 is unified without interruption, and a predetermined voltage from the power supply in the control unit 10 is applied between the terminals a and b of the heating elements 3 and 3 located at both ends of the eaves of the roof 1. (AC voltage) is applied. The control unit 10 has a built-in temperature adjusting means, which changes a voltage value (or a current value) applied between the terminals a and b, , b, this period is changed when a voltage is applied periodically.

The number and arrangement of the terminals a and b, the number of the control units 10, and the presence or absence of the temperature control means are not limited to those described above, and the design can be changed as appropriate. As an example, as shown in FIG. 5, power supply lines A and B are stretched along both edges of the roof 1 and each heating element 3... 3 is connected to the power supply lines A and B via a connector. The same control unit 1 as described above is connected between terminals a and b connected in parallel and attached to the power supply lines A and B.
Connect 0.

On the other hand, the heating element 3 does not have to use the above-described heating wire or the like, and as shown in FIG.
A so-called induction current heating tube formed by passing an insulated wire 12 through the inner hole of the steel tube 11, that is, a device that generates heat by using an induction current (for example, as described in the “Electrical Engineering Handbook” edited by the Institute of Electrical Engineers of Japan, 1978, page 1578, etc.) ) Can also be used.

The heating element 3 may be a tubular member through which a fluid heat medium (for example, hot air or hot water) flows through an inner hole.
In this case, it is necessary to separately provide a fluid heat medium supply unit in place of or together with the control unit 10 described above.

According to the above configuration, when a predetermined voltage is applied between the terminals a and b from the control unit 10 shown in FIG. 1 or FIG. 5, the heating elements 3.
Accordingly, the continuously formed plate members 2... 2 are loosened and conduct heat satisfactorily over a wide range, so that the entire surface of the roof 1 is reliably heated. Further, a continuous space A shown in FIG. 3 is provided between the heat-insulating material 8 and the continuous molded plate materials 2...
... A is formed, so that the air intensively heated by the action of the heating elements 3 ... 3 at the eaves of the continuous space A passes through the continuous space A and rises to the ridge side. Therefore, a suitable temperature rise due to the heated air occurs not only in the eaves portion but also in the ridge portion of the continuously formed plate members 2... 2 so that the continuously formed plate members 2. It is performed well, and various adverse effects due to snow are avoided. In addition, if the temperature adjustment means is incorporated in the control unit 10, it is possible to suitably cope with the difference in the amount of snow on the roof, the difference in the temperature, and the difference in the area.

[Effect of the invention]

Since the snow-melting roof structure according to the present invention is configured as described above, it has the following effects.

That is, according to the snow-melting roof structure of claim (1), a continuous molded plate that is long at least in the direction from the eaves to the ridge is used as the roofing material, and is substantially horizontal below the continuous molded plate. The heat applied to the continuously formed plate from the heat generator is reliably conducted in the direction from the eaves to the ridge, and suitable heat conduction is performed over the entire roof. Therefore, snow melting on the roof is performed well, and various adverse effects due to snow in a heavy snow area are effectively avoided.

Further, according to the snow melting roof structure according to claim (2), since the heating elements are arranged closer to the eaves than to the ridge, the action of the heating elements at the eaves of the continuous space below the continuously formed plate material. The air heated intensively floats in the continuous space toward the ridge side, whereby the heating action on the continuously formed plate material and, consequently, the snow melting on the roof can be performed efficiently and economically.
