Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to a structure for preventing snow accumulation on a roof.

(b) Prior Art Conventionally, in snowy regions, snow accumulates on roofs, and snow removal work is carried out regularly to prevent houses from being soaked in the snow.

Such snow shoveling work involves workers climbing onto the roof and using tools such as shovels to shovel the snow, which is extremely dangerous as workers may accidentally fall from the roof to the ground and be injured.

Therefore, in order to solve the above-mentioned drawbacks, a snow removal device is attached to the roof to remove snow from the roof.

Such a snow scraping device is configured such that a scraping plate is rotatably disposed on the roof, and the scraping plate is used to scrape off accumulated snow from the roof.

(c) Problems to be Solved by the Invention However, in the above-mentioned snow scraping device, the scraper is operated via a drive motor, and the scraper is not smoothly operated due to the weight of the snowfall or the freezing of the drive motor due to the snowfall. It had the disadvantage that it did not work properly.

In addition, since such a snow removal device is attached to the roof of a house, there is a risk that the exterior appearance of the house may be damaged.

(d) Means for Solving the Problems The present invention stores a heat pipe for melting snow along the slope of the roof of a house, and also supplies a heat medium from a heater to the lower end of the heat pipe. The present invention provides a snow and earth prevention structure in a roof portion characterized by a communication connection.

(E) Functions and Effects In the present invention, when snow falls on the roof of a house, a heating medium is supplied from the heater to a heat pipe stored in the roof, and the heat pipe heats the roof. This allows the snow on the roof to melt.

The snow melted by the heat pipe can easily slide along the slope of the roof and fall below the roof.

In addition, since the heat pipe is housed along the slope of the roof, the lower end of the pipe is heated by the heat medium from the heater, and the working fluid inside the heat pipe is circulated smoothly. This allows for efficient heat dissipation.

Moreover, since the heat pipe that melts snow is housed inside the roof, it does not damage the appearance of the house, and it also heats the roof of the house and releases as much heat as possible inside the house. It is possible to prevent this from occurring and also provide insulation for the house.

(F) Embodiment An embodiment of the present invention will be described in detail with reference to the drawings. In the sectional view of FIG. 1, A indicates a house according to the present invention, and the house A is constructed as follows.

That is, the roof part 1 constitutes a gable roof, and the girders 3 are attached to the upper ends of a large number of columns 2 erected at the foundation of the house A, and the land beams 4 are installed on the girders 3. A large number of main buildings 6 are erected in an inclined manner from the center of the land beam 4 to the left and right through bundles 5 at regular intervals.

Moreover, as shown in FIGS. 1 and 2, a large number of rafters 7 are installed at intervals on top of the main building 6.
A roof board 10 for attaching a roof member 9 such as a tile or iron plate is stretched over the same tarp 7.

In addition, 11 is a fascia attached to the lower end of the barrel 7;
2 is a ridgepole at the top of the roof portion 1, and 13 is a ridge bundle of the ridgepole 12.

As shown in FIG. 1 and FIG. 2, the present invention includes a heat panel 14 attached to the roof 1, and
4, the roof part 1 is heated to melt snow accumulation, and its structure will be explained in detail below.

That is, in the heat panel 14, as shown in FIGS. 2 and 3, a long rectangular panel main body 14a is filled with a heat insulating material C, and a heat pipe 15 is housed in the longitudinal direction.

The heat pipe 15, as shown in FIG. 2, is made of a long metal pipe body, which is kept in a vacuum state and is filled with a working fluid such as helium, ammonia, or water.

Further, a heat dissipating section 15a is formed on one side of the heat pipe 14, and a heat receiving section 15b is formed on the other side of the vibrator 14.
is formed.

When the heat pipe 15 heats its heat receiving part 15b, the gasified working fluid moves to the heat radiating part 15a,
Heat is radiated from the heat radiating portion t5a.

Further, the working fluid in the heat radiation section 15a is liquefied by heat radiation, and circulates within the heat pipe 15 along the inclined inner surface of the heat pipe 15 to the heat receiving section 15b.

In this embodiment, as shown in FIG. 2, the heat dissipating portions 15a of the two heat pipes 15 are arranged along the longitudinal direction of the panel body 14a, and the heat receiving portions 15b of the heat pipes 15 are arranged along the longitudinal direction of the panel body 14a. It sticks out at one end.

A heat sink 16 is housed in the heat panel 14 in contact with the heat sink 15a of the heat pipe 15. The heat sink 16 is made of a metal plate with excellent thermal conductivity, as shown in FIG. In addition, it is disposed over the entire upper surface of the panel body 14a.

Further, the heat dissipation plate 16 has curved recesses 16 on the left and right sides.
a, and the heat panel 14 is placed inside the curved recess 16a.
The heat dissipation plate 16 is housed therein, and the heat dissipation plate 16 is configured to smoothly conduct heat from the heat dissipation plate 16.

In this embodiment, as shown in FIGS. 1 and 2, the heat panel 14 is installed between the roof part 1 and the rafter 7, and the heat receiving part of the heat pipe 15 is attached along the rafter 7. 15b is attached in an inclined manner with the part facing downward.

Therefore, since the heat receiving portion 15b of the heat pipe 15 is directed downward, the heat panel 14 allows the working fluid to circulate smoothly and radiates heat efficiently.

Furthermore, a heat pipe 1 is provided at the lower end of the barrel 7.
A heat header 17 for connecting the heat receiving portions 15b of No. 5 is provided.

The heat header 17 is formed into a long length and is disposed along the edge of the roof portion 1. Furthermore, a communication hole is provided on the inner surface of the header 17, and a joint portion 17a is formed in the communication hole. The heat receiving portion 15b of the heat pipe 15 is connected via the heat pipe 15.

In addition, as shown in FIG. 4, the heat header 17 has
A boiler 20a, which serves as a heater 20, is connected through communication vias 18 and 19.

In addition, 21 is a pump provided in the communication vibrator 18,
The pump 21 circulates hot water from the boiler 20a to the heat header 17.

With this structure, hot water from the boiler 20a is supplied to the heat heater 17, the heat receiving part 15b of the heat pipe 15 is heated by the header 17, and the heat radiation part 15a of the vibrator 15 and the heat radiation plate 16 generate heat. It is configured to radiate heat from the entire surface of the panel 14 and efficiently heat the roof part 1.

In this embodiment of the present invention, the heat panel 14 is constructed of heat pipes 15 and is attached between the rafters 7 of the roof section l; however, as another embodiment, when the roof section 1 is constructed, In this case, it is also possible to install a heat insulating material C, a heat pipe 15, etc. between the rafters 7 to form the roof part l.

As described above, this embodiment has the following effects.

In the present invention, when snow falls on the roof 1 of the house A, hot water is supplied from the boiler 20a serving as the heater 20 to the heat pipe 15 in the heat panel 14 disposed on the roof 1 to heat the same. By heating the roof part 1 with the pipe 15 and the heat sink 16, snow accumulated on the roof part 1 can be melted.

The melted snow then slides down along the slope of the roof l, allowing the snow on the roof l to be removed.

In addition, since the heat panel 14 is installed along the sloped rafter 7 of the roof 1, when the heat receiving part 15b located at the lower part of the heat pipe 15 in the panel 14 is heated, the temperature inside the heat pipe 15 increases. By smoothly circulating the working fluid, heat can be dissipated more efficiently from the heat panel 14.

Moreover, since the heat panel 14 for melting snow is housed within the roof section 1, it heats the roof section 1 of the house A and prevents the release of heat inside the house A as much as possible. The insulation effect of house A can also be obtained.
