Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow melting panel for melting snow accumulated on railroad crossings and roads in cold regions, and a snow melting device using this snow melting panel.

[0002]

2. Description of the Related Art Conventionally, a hot water pipe for snow melting is buried in a panel body, and the end of the hot water pipe is led out from a recess formed in the panel body to melt the snow in consideration of the connectivity between the snow melting panels. Panels are known (for example, JP-A-57-6).
002, JP-A-64-36803, and JP-A-64-36804).

Further, a plurality of snow melting panels and a heating circulator for circulating heated hot water in hot water pipes of these snow melting panels are connected by pipes to be used as a snow melting device. As the snow melting device, various types such as a header system, a branch system, and a reverse turn system have been proposed depending on the difference in the connection state between the snow melting panel and the heating circulator.

[0004]

However, in the case of the above-described conventional snow melting apparatus, when the snow melting panel and the heating circulator are connected by piping, the piping is exposed around the snow melting panel. Therefore, a U-shaped groove member or the like for shielding and protecting this exposed pipe must be separately installed around the snow melting panel, resulting in inconvenience that the number of construction steps and the construction cost are high. In particular, when the snow melting device is arranged at a railroad crossing, it must be constructed within a limited time period from the passage of the last train to the passage of the first generator car, which makes the construction troublesome.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a snow melting panel which is simple and quick in construction and excellent in workability, and a snow melting apparatus using the snow melting panel.

[0006]

A snow melting panel of the present invention for solving the above problems is a snow melting panel in which a hot water pipe for snow melting is embedded in a panel body, and the panel body has a hot water pipe. A pipe passage for passing the pipe to the is formed.

Further, a snow melting apparatus of the present invention for solving the above-mentioned problems is a snow melting apparatus comprising a snow melting panel and heating circulation means for circulating hot water heated in a hot water pipe of the snow melting panel. A plurality of panels are laid, and these snow melting panels or between the snow melting panel and the heating circulation means are connected via piping to a piping passage provided in the snow melting panel.

[0008]

According to the snow melting panel of the present invention, the pipe to the hot water pipe can be routed to the pipe passage provided in the panel body.

Further, according to the snow melting apparatus of the present invention, since the snow melting panels or between the snow melting panel and the heating circulation means are connected to the piping passage provided in the snow melting panel via piping, this piping passage This will shield and protect the piping.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the outline of the entire structure of the snow melting panel 1, and FIG. 2 shows various snow melting devices 10 constituted by the snow melting panel 1.

That is, the snow melting panel 1 comprises a hot water pipe 3 for snow melting buried in a panel body 2, and a pipe passage 2 for passing a pipe 4 to the hot water pipe 3 in the panel body 2.
0 is formed.

The panel body 2 is formed of concrete, asphalt, or the like into a plate shape having an appropriate thickness. In addition, for convenience of explanation, each side surface of the panel body 2 is separated by two.
1, 22, 23, and 24.

The hot water pipe 3 is formed of a metal pipe or the like having a high heat transfer coefficient. The panel body 2 is embedded in the panel body 2 so that the panel body 2 has a meandering shape parallel to the side surfaces 22 and 24 and folded back at the side surfaces 21 and 23. Further, in this buried state, both end portions 3 of the hot water pipe 3 are
The reference numerals 1 and 32 lead out from the side surface 21 of the panel body 2.

The piping passage 20 is provided so as to penetrate from the side surface 21 to the side surface 23 along the side surface 22 of the panel body 2. The pipe passage 20 has a quadrangular cross section, but is not particularly limited to a quadrangular cross section, and as shown in FIG. 3, has a circular cross section (see FIG. 3 (a)),
It may have an elliptical shape (see FIG. 3B) or the like. Further, although the pipe passage 20 is hollow, it is not particularly limited to a hollow one.
It may have a groove shape opened on the side surface 22 of the panel body 2 over the entire length (see FIG. 3 (c)) or a groove shape opened on the upper surface 25 (see FIG. 3 (d)). The lower surface 26
It may have a groove shape with an opening (see FIG. 3 (e)).

The pipe passage 20 is not particularly limited to the one extending along the side surface 22, but other side surfaces 21 and 21.
It may be provided along 3, 24, or may penetrate the central portion of the panel body 2. The piping passage 20 is not limited to one place along the side surface 22 of the panel body 2, and, for example, as shown in FIG.
It may be provided in two places along the side surfaces 2, 23, three places along the side surfaces 22, 23, 24, or in the entire side surfaces 21, 22, 23, 24.

Further, in this case, the hot water pipe 3 also has both ends 3
1, 32 are not limited to those derived from the side surface 21 of the panel body 2, and other side surfaces 22, 23, 24
The end portions 31 and 32 may be derived from the opposite side surfaces 21 and 23 or the adjacent side surfaces 21 and 23.
The end portions 31 and 32 may be led out from the pipe 22, respectively.
32 may be derived. However, when the ends 31, 32 of the hot water pipe 3 are directly led to the hollow pipe passage 20, the ends 31, 32 of the hot water pipe 3 are taken into consideration in consideration of the connectivity with the pipe 4. Is preferably led to the outlet of the pipe passage 20.

The snow melting panel 1 thus constructed
By passing the pipe 4 through the space 20, the pipe 4 can be freely routed around the snow melting panel 1. Therefore, as shown in FIG. 2, the snow melting panels 1 having the various spaces 20 described above are combined, and the hot water pipes 3 of these snow melting panels 1 are connected to the heating circulator 5 and the header 6 by the pipes 4. By this, the header method (see Fig. 2 (a)),
Branch method (see Figure 2 (b)), reverse turn method (Figure 2)
(See (c)) and other various types of snow melting devices 10. Further, when the snow melting device 10 is installed, the pipe 4 can be installed in the space 20 to conceal and protect the pipe 4, so that the snow melting device 10 can be installed easily and quickly. Therefore, in particular, even when these snow melting devices 10 are arranged at the level crossings, it is possible to carry out the construction within a limited time period from the passage of the last train to the passage of the first power generation vehicle. Further, in this case, as shown in FIG. 5, the groove portion 2 for arranging the line 7 in advance is provided.
When the snow melting panel 1 for railroad crossing laying formed with 7 is used, the construction can be performed more efficiently.

In addition to the railroad crossings, these snow melting devices 10 can be used for road surfaces such as roads and parking lots, and wall surfaces of buildings.

[0020]

As described above, according to the snow melting panel of the present invention, since the piping to the hot water pipe can be arranged in the space, the piping member required when constructing the snow melting panel. Can be omitted and the construction work can be performed easily and quickly. As a result, it is possible to simplify the construction, shorten the construction period, and reduce the construction cost.

Further, according to the snow melting apparatus of the present invention, since the pipe is shielded and protected by the space of the snow melting panel without using a member for piping, the construction can be simplified, the construction period can be shortened, and the construction cost can be reduced. It is possible to reduce the construction cost, and it can be effectively installed even in places such as railroad crossings where construction must be done within a limited time.
