Description

Description: TECHNICAL FIELD The present invention relates to an improvement in a roof structure, and more particularly to a technique for satisfactorily 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 plate. 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 a troublesome and complicated snow removal operation such as snow removal is performed.

Further, when the above-described continuous molded plate material is used as a roofing material, the structure between the continuous molded plate material and the heat insulating material becomes peculiar. In order to ensure that the snow on the roof disappears without inviting the snow, it is important to consider what measures are best to take.

The present invention has been made in view of the above circumstances, and by effectively utilizing a space below a roofing material and laying a new structure, a roof structure can be surely provided without complicating the structure. It is a technical task to make it possible to cope with the snow cover of the city.

[Means for solving the problem]

A specific means for achieving the above technical problem is a roof structure using a vertically long continuous formed plate material as a roofing material at least from the eaves portion to the ridge portion, and a heat source and A blower for forcibly sending the air heated by the heat source as hot air to form hot air generating means, and an inner hole through which the warm air supplied from the hot air generating means flows, and A blower tube formed with a ventilation hole through which hot air is blown out from the hole is disposed in a space below the continuous molded plate material so that the eaves portion is denser than the ridge portion, and is blown out from the blower tube. There is an outlet on the roof ridge that discharges the heated air to the outside.

[Action]

According to the above means, as a basic configuration, the warm air generated by the warm air generating means is forcibly supplied to the blower tube and the warm air is blown from the blower tube into the space below the roofing material. Because of this configuration, the lower space is filled with air in a high-temperature state, and accordingly, the roofing material covering the lower space is heated, and snow melting on the roof is performed well. in this case,
The lower space described above is specifically a gap between the asphalt roofing or the heat insulating material and the roofing material above the base plate. In this way, by effectively utilizing the space under the roofing material, which is an existing preferred space, in the roof of a building as a place for blast pipes and a space for blowing hot air,
It is possible to efficiently melt snow on the roof without causing a space problem or the like, and the harmful effects of snow on buildings in a snowy area are reduced as much as possible.

In addition, a continuously formed plate material is used as a roofing material, and the hot air generating means is constituted by a heat source and a blower for forcibly supplying hot air heated by the heat source, and is provided below the continuous formed plate material. In the space, a ventilation pipe having an inner hole through which the warm air supplied from the warm air generating means flows and a ventilation hole for discharging the warm air is provided, so that the air heated by the action of the heat source is provided. Is forcibly supplied to the inner hole of the blower tube by the action of a blower (for example, a blower fan), and warm air is blown from the inner hole of the blower tube into the space below the continuously formed plate material through the ventilation hole. As a result, the continuously formed plate material is suitably heated, and this type of roof snow melting is favorably performed. In this case, since the blower tubes are densely arranged at the eaves portion compared to the ridge portion of the roof, in other words, since the blower tubes are concentrated at the eaves portion, continuous Warm air blown intensively at the eaves side of the lower space of the formed sheet material rises toward the ridge side, so the continuous formed sheet material is sure not only at the eaves part but also at the ridge part. As a result, the roof can be efficiently and economically melted.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

First, the schematic configuration of a snow-melting roof structure according to the present invention will be described with reference to FIG. 1. In the roof 1 of the building, a plurality of continuously formed plate members 2 are used as roofing members. 2 are formed of steel plates, and the size of one continuous formed plate 2 is such that a large number of tiles of normal size are arranged in the vertical direction from the eaves to the ridge, and The horizontal direction perpendicular to this is equivalent to the size of a small number of tiles of a normal size, and is obtained by molding into a predetermined shape by molding or the like. Below these continuous formed plate members 2, a plurality of blower tubes 3, 3 extending in the lateral direction are arranged. In this case, as is clear from the figure, the arrangement of the air ducts 3... 3 is arranged more densely at the eaves than at the ridge of the roof 1.

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. The fixing member such as a nail is driven into the base plate 6 from above the continuous formed plate member 2 in such a state, whereby the continuous formed plate member 2 is insulated through the heat insulating material 8 and the asphalt roofing 7. It is in a state where it is firmly fastened. Then, in such a state, the above-described blower tube 3 is disposed in a gap between the continuous molded plate 2 and the heat insulating material 8, that is, in a space A below the continuous molded plate 2. As is apparent from FIG. 3, a plurality of rows extending continuously from the eaves to the ridge below the raised portion 2a of the continuously formed plate 2 between the continuously formed plate 2 and the heat insulating material 8. Ax ... Ax are formed.

As shown in FIG. 4, a plurality of ventilation holes (small holes) 9... 9 are formed on the peripheral surface of the ventilation tube 3, and the ventilation holes 9 extend from the inner hole 3 a of the ventilation tube 3. The hot air is blown into the lower space A of the continuously formed plate material 2 through the hot plate 9.

On the other hand, for this embodiment (see FIG. 1), the heat source 10
Hot air generating means 12 comprising a fan and a blowing device (blowing fan) 11
On both sides of the ridge of the roof 1, there are vertically arranged communication pipes 13 and 13 that communicate with the air blow pipes 3... It is connected to the hot air generating means 12 via supply pipes 14,14. Therefore, the warm air generated by the warm air generating means 12 is supplied to the main feed pipes 14 and 1.
After being forcibly sent to the communication pipes 13 via the connection pipe 4, the delivery pipes 13 and 13 deliver the air to the inner holes 3a... 3a of the air blow pipes 3. The air is blown into the lower space A of the continuously formed plate 2 through the ventilation holes 9 of the pipes 3. In this case, by connecting the main return pipes 15 and 15 between the communication pipes 13 and 13 and the hot air generation means 12, a closed loop circulation system is adopted, and the hot air generation means 12 connects the communication pipes 13 and 13 with each other. The supplied residual air may be recovered by the hot air generating means 12 again, or as an open loop system without providing the main return pipes 15 and 15 as described above, the hot air generating means 1
A configuration may be adopted in which warm air is unilaterally supplied from 2 to the communication pipes 13 and 13 and the air blow pipes 3.

This hot air circulation route will be described in further detail. As shown in FIG. 2, a hot air generating means 12 is installed in the attic, and a communication pipe 13 is provided along the lower side of the base plate 6 to provide the communication. Each of the blower pipes 3... 3 is connected to each of the branch pipes 13 x and 13 x branched from the pipe 13 and penetrating the field board 6 and the heat insulating material 8.

In addition, the number and arrangement of the communication pipes 13, 13 and the main supply pipes 14, 14, and further, the number and location of the hot air generating means 12 are not limited to those described above. Various variations are possible.

Further, the heat source 10 of the hot air generating means 12 does not have to use an electric heater as in the above example, and may generate heat using coal, oil, firewood, or the like, or A configuration in which the main feed pipe 14 is connected to the chimney of the stove may be adopted, and further, geothermal (well) may be used.

According to the above configuration, the air heated by the action of the heat source 10 of the hot air generating means 12 shown in FIG. 1 or FIG.
Due to the action of the air blower 11, the air is forcibly fed from the main feed pipe 14 to the communication pipe 13.
, And then the ventilation holes 9 of each blower tube 3.
9 are jetted into the lower spaces A... A of the continuously formed plate material 2. Thus, the lower spaces A... A of the continuous formed plate 2 are filled with high-temperature air, and the continuous formed plate 2 covering the lower spaces A. As a result, snow melting on the roof in a snowy area is performed favorably. When the open loop method is adopted without providing the main return pipe 15, the warm air blown into the lower space A... Is discharged to the outside through a discharge port (not shown) provided in the printer.

In this case, in the above embodiment, the air ducts 3... 3 are arranged in the horizontal direction. However, the present invention is not limited to this, and the air ducts 3. Ax shown in the drawing may be arranged in the vertical direction.

〔The invention's effect〕

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

That is, at least a blower tube is arranged in a space below a vertically long continuous formed plate member extending from the eaves front portion to the ridge portion, and the warm air heated by the action of the heat source of the warm air generating means is provided by the blower. The air is forcibly supplied to the blower tube by the action, and the hot air is blown into the lower space of the continuously formed plate material through a ventilation hole formed in the blower tube. The action of the wind heats the continuously formed plate material, so that the snow on the roof is melted well, and the existing space below the continuously formed plate material is effectively used.

Furthermore, since the blower pipes are arranged closer to the eaves than to the ridge of the roof, the warm air intensively blown out at the eaves of the space below the continuous molded plate material moves the space to the ridge side. As a result, not only the eaves but also the ridge of the continuously formed sheet material are efficiently heated, and the snow melting on the roof is performed economically.
