Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a circulating roof snow melting device that uses a heat medium such as hot water or hot air.

[0002]

[Prior art]

The heat insulating material, 7 is a hot water circulation pipe for circulating hot water on the roof surface, and reference numeral 8 is a soaking plate that transfers the heat of the hot water circulation pipe 7 to the entire roof surface.

The heat insulating material 6 is attached to the entire roof so as to have a uniform thickness, and the heat insulating material 6 is provided with recesses 10 for burying the hot water circulation pipe 7 which are alternately bent toward the ridge and toward the eaves. Is formed. The heat equalizing plate 8 is attached to the surface of the heat insulating material 6, and the hot water circulation pipe 6 is continuously installed in the recess 9. The heat insulating material 6, the hot water circulation pipe 7 and the heat equalizing plate 8 are completely covered by the roofing material installed on the heat insulating material 6.

[0004]

[Problems to be solved by the device]

 The conventional snow melting device is configured as described above, but since the hot water circulation pipe 6 is formed as a continuous continuous circulation pipe for a considerable length of time, a temperature difference occurs on the pipe surface near the start point and the end point. In addition, since the hot water circulation pipe 6 is installed along the direction of the roof slope, air may accumulate near the ridge, which causes uneven temperature on the roof surface and uneven snow melting. There was a drawback that it would occur.

In addition, since most of the work is done on site, it is inevitable that the construction period will be lengthened. Furthermore, when repairing hot water circulation pipes, it is necessary to remove the roofing material, which is a drawback that large-scale construction is likely to occur.

The present invention has been proposed in order to solve the above-mentioned conventional problems, and provides a snow melting apparatus having extremely high snow melting efficiency and capable of being easily constructed and repaired. That is the purpose.

[0007]

Are installed so as to reciprocate in the direction of the roof slope, and the forward end and the return end of the heat radiation pipe are connected to the forward and return pipes of the main pipe, respectively.

According to a second aspect of the present invention, there is provided a circulation type roof snow melting apparatus, wherein a plurality of casings are arranged side by side in a lateral direction of the roof in a slope direction of the roof, and a heating medium is provided in a ridge portion inside each of the casings. The forward and return pipe units of the main pipe that circulate the heat are installed respectively, and the forward and return pipe units are connected to make a reciprocating main pipe, and the heat medium is circulated in each casing. The pipe is installed by reciprocating, and the outgoing pipe end and return pipe end of the heat radiation pipe are connected to the outgoing pipe and return pipe units of the main pipe, respectively.

[0009]

[Action]

 In the circulating snow melting device according to the first and second aspects of the present invention, the heat radiation pipe is heated by a heat medium such as hot water flowing through the heat radiation pipe, and the heat radiation pipe causes the heat radiation pipe to be evenly distributed over the entire roof surface. It is warmed and the snow melts.

【Example】

 FIG. 1 is a partial perspective view of an embodiment of the snow melting apparatus according to the present invention, and FIG. 2 is a sectional view thereof. In the figure, reference numerals 1 and 2 are a main pipe and a heat radiating pipe for circulating a heat medium such as hot water or hot air, 3 is a casing for housing the main pipe 1 and the radiating pipe 2, and 4 is hot water circulating in the main pipe 1 and the heat radiating pipe 2. A heating source for storing heat medium such as hot air and hot air, and reference numeral 5 is a roofing material.

The main pipe 1 is formed as a single circulation pipe that reciprocates from a forward pipe 1a and a return pipe 1b, and is piped along a roof ridge in a casing 3 of a roof ridge part, and its end is a heating source. Connected to 4. The forward pipe 1a and the return pipe 1b are unitized for each casing 3, and are connected to each unit to form a continuous forward pipe 1a and a return pipe 1b along the ridge.

The radiating pipe 2 is formed as a single reciprocating circulation pipe that is continuous in a U shape from the forward pipe 2a and the returning pipe 2b, and extends from the ridge to the eaves along the slope of the roof in each casing 3. Have been installed. Further, the end of the forward pipe 2a of each heat radiation pipe 2 is connected to the forward pipe 1a of the main pipe 1, and the end of the return pipe 2b is connected to the return pipe 1b of the main pipe 1.

It should be noted that the radiating pipe 2 may be installed separately in the casings 3 and 3 which are adjacent to each other, and the outward pipe 2a and the return pipe 2b may be installed separately so as to extend across the two casings 3 and 3 (see FIG. 5).

The casing 3 is formed of a metal plate or the like in the shape of an elongated rectangular box along the slope direction of the roof. A roofing material 5 is installed on the casing 3, and the roofing material 5 completely covers the main pipe 1, the heat radiation pipe 2 and the casing 3.

In such a configuration, when a heat medium such as hot water or hot air is circulated in the main pipe 1 and the heat radiating pipe 2, the roof surface is warmed and snow melting on the roof surface becomes possible.

It should be noted that, in the embodiment, the roof circulation type snow melting apparatus has been described, but it goes without saying that it can be applied as a snow melting apparatus for a floor portion such as a platform.

[0017]

EFFECTS OF THE INVENTION Since the circulating roof snow melting device according to the present invention is configured as described above, it has the following effects.

Since the radiating pipe is formed as a reciprocating pipe and the plurality of radiating pipes are installed at predetermined intervals according to the size of the roof, the moving distance of the heat medium such as hot water flowing in the radiating pipe. Is extremely short, and the temperatures near the start and end points of the heat dissipation pipe are almost the same. In addition, since the main pipe is installed in the roof ridge and the outward and return pipe ends of the heat radiating pipe are connected to this main pipe, the air inside the radiating pipe can be easily evacuated, so that heat is constantly radiated. It is possible to keep the heat medium in circulation in all parts of the pipe. Therefore, the surface temperature of the roof can be made uniform and efficient snow melting is possible.

Further, since the main pipe and the heat radiating pipe are installed in the casing and are unitized, the construction and the repair can be easily performed.
