[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the case where the present invention is applied to a platform according to a first embodiment will be described with reference to FIG.
Since the train getting on and off point 1a of the platform 1 is not completely covered with the roof, it is easy to carry snow. In addition, the train passes at a high speed in the immediate vicinity, which is very dangerous. In particular, even if the amount of snow is small, a large accident due to falling easily occurs.

Therefore, the snow melting device A according to the present invention is mounted on the entire lower surface 1b of the platform 1 on the lower surface 1b (normally opened as shown in FIG. 1) of the train getting on / off point 1a. Partial attachment may be used, but the entire lower surface 1b is desirable to avoid heat radiation from the lower surface 1b. Due to the heat from the snow melting device A, the support plate of the platform 1 at the platform 1a is warmed from below, and the snow melts immediately even when the snow falls on the support plate at the platform 1a.

[0103] Train Platform 1a of Normal Platform 1
The thermal conductivity of the support plate is low because concrete is often used. Therefore, in snow melting experiments using the device of the present invention,
According to this, it is desirable to start the heating by supplying electricity about eight hours before the snowfall start time .

Next, the snow melting apparatus A will be described. FIG.
Shows a state in which the snow melting device A is mounted on the lower surface 1b of the platform 1, and the support plate lower surface 1 of the train getting on / off point 1a is shown.
b, and a foam board 5 from below.
And is fixed to the support plate by fixing pins 6 via. In the case where the foam board 5 has a gap opened even after the side face thereof is fixed by the pin 6 and there is a risk of heat leakage, a sealing rising portion (not shown) may be formed on the peripheral face of the side face. Good.

If the fixing pin 6 can be detached from the lower surface 1b of the support plate at the place 1a for getting on and off the train, it is convenient for maintenance of the heater 4 and the foam board 5. Further, the pin 6 may be fixed by an adhesive instead of the pin 6. In this case, since high heat is generated from the heater 4,
A thermosetting and heat-resistant material must be selected. In this case, it is desirable that the volume change due to heat is small.

FIG. 3 shows a state in which another type of snow melting apparatus A is also mounted on the lower surface of the platform 1. A heater 4 is disposed on a lower surface 1b of a support plate of a train getting on / off place 1a. After the heater 4 is supported by the heater supporting net 7, the fixing pins 8 are used to fix the heater 4 together with the heater supporting net 7.
Is fixed to the lower surface 1b of the support plate at the place 1a of getting on and off the train. Then, the foam 9 is sprayed from below to a certain thickness to form a heat insulating layer.

The snow melting apparatus A shown in FIGS.
Means for integrally fixing the lower surface 1b of the snow-covered portion has been described. For example, the heater 4 is previously mounted and fixed on the upper surface of the foam board 5, or the heater 4 is embedded in the foam board 5 in advance. Then, the integrated body (heating plate A) of the heater 4 and the foam board 5 may be firmly fixed integrally with the lower surface 1b of the snow-covered portion by the fixing pin 8 or the like.
In this case, if you attach it detachably by means of bullets,
This is convenient for subsequent maintenance management.

Next, a case where the present invention is applied to a roof according to a second embodiment will be described with reference to FIG. Naturally, in a house in a snowy area, snow easily accumulates on the roof 2. Particularly, the snow may remain forever on the eaves portion 2a of the roof, in combination with the falling snow from the upper part of the roof. The eaves portion 2a has a problem that it is easily affected by the weight of snow since its support is in a cantilever state, and the eaves portion 2a of the roof is easily damaged due to the weight of the icicles during the remaining snow season. . The present invention
This problem has been solved by installing a snow melting device A on the lower surface 2b of the eaves tip 2a of the roof. The structure and mounting means of the snow melting apparatus A are the same as in the first embodiment (in the case of a platform). The capacity, size, and the like of the snow melting apparatus A are design matters.

Since the eaves portion 2a of the roof is heated from the lower surface by this groove formation, it is possible to avoid snow at least at the eaves end. In this case, it is not particularly necessary to energize the heater before the snowfall, and the snow melting device A may be operated in view of the snow cover on the roof.

Next, a case where the present invention is applied to a staircase according to a third embodiment will be described with reference to FIG. The stairs 3 installed outdoors are slippery, for example, the stairs at the station are long,
And because of the difference in height, snowy days are not only snowy,
It is very dangerous because it easily freezes. Therefore, as shown in FIG. 5, the snow melting device A of the present invention is provided on the lower surface 3a of the tread plate of the stairs 3.
Is installed. The structure and mounting means of the snow melting apparatus A are basically the same as those of the first embodiment. With this structure, the tread of the stairs 3 is warmed from the lower surface 3a, and snow and freezing can be avoided.

[0021]

According to the present invention, in a snow melting apparatus for a building, all the disadvantages of the snow melting apparatus in a conventional building can be solved. (1) It is possible to provide a relatively simple cost snow melting apparatus, and even if it is an existing building, additional and necessary
This is a highly versatile technology because a snow melting device can be provided only at a specific location . (2) When the installation operation of the snow melting apparatus, installation location is the product
Since it is the lower surface via the structural member of the snow part, the workability is improved without being affected by weather conditions. Moreover, since it can be constructed separately from concrete construction using heavy materials such as gravel and water, there is no need to consider quality control during construction of the snow melting apparatus. (3) Since the installation location of the snow melting device is on the lower surface of the snow covered portion, it is hardly affected by the water after snow melting and the external weather conditions, and therefore, the durability is improved. (4) Even where a person stands on a platform or a staircase, there is no need to consider from the viewpoint of safety, and the design is easy.

(5) Since the snow-melting device is not provided as an internal structure, it is not necessary to consider the installation of the snow-melting device from the beginning of the design, and there is no need to consider the applied mechanical properties of the structure. A significant increase can be avoided. (6) Even if the concrete physically and scientifically changes with time, since the heater and the like are not provided as an internal structure, the heat transfer efficiency and durability of the heater and the like are not affected. (7) By unitizing the snow melting device, the main parts or all can be manufactured in advance by factory production instead of construction at the site, so that the quality of the snow melting device and installation work can be advanced and uniformed.
