Abstract

PURPOSE:To discharge water quickly after snow is melted by inclining the surface of snow melting panels which incorporate a heat generating pipe or a heat generator or the bottom face of a groove provided on the surface of the snow melting panel. CONSTITUTION:A plural number of snow melting panels 1 in which a heat generating pipe or a heat generator is embedded in the inside are installed on roadway and sidewalk in a region of heavy snowfall to melt snow by heat from the heat generating pipe or the heat generator. At this time, inclination is provided in advance on the surface of the snow melting panel 1 to make a slope. And, water produced after snow is melted travels along the inclined face and is discharged outside of the snow melting panel 1 from a lowermost end 5. Or, a drain ditch may be provided at the tip of the lowermost end 5 to collect water in the drain ditch and discharge water. Also, a groove whose bottom face is inclined may be provided on the snow melting panel having horizontal surface to discharge water produced after snow is melted. Consequently, it is unnecessary to provide a base itself on which the snow melting panels 1 are installed with inclination and it is possible to save labor of the construction.

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 used for snow melting on a road surface such as a roadway or a sidewalk in a snowy area, or at a level crossing.

[0002]

2. Description of the Related Art Conventionally, as a snow melting panel used for snow melting on road surfaces such as roads and sidewalks in heavy snowfall areas and at railroad crossings, for example, as shown in FIG. 10, hot water in a panel body 70 such as concrete or asphalt is used. A snow melting panel in which a pipe 71 and a reinforcing bar 72 are embedded is disclosed and known in JP-A-64-36803 and JP-A-64-36804.

Further, as shown in FIG. 11, when an insulated electric wire is passed through a steel pipe having a ferromagnetism without being fixed, and an alternating current is passed through this insulated electric wire, an alternating current near the inner skin of the steel pipe is a primary current. The secondary current to
Induction skin current heating pipe 80 configured so that the next current does not practically flow, or an insulated wire and a steel pipe are connected in series to an AC power source, and the current flows concentratedly only near the inner skin of the steel pipe. A concrete block with an electric snow melting device, in which a plurality of series skin current heating tubes configured so that current does not practically flow to the outside is arranged in a concrete block 82 reinforced by a reinforcing bar 81, is a concrete block with an electric snow melting device. -6002
It is disclosed and known in the publication.

By the way, in the above-described conventional snow melting panel, the surface 73, 83 and the back surface 74, 84 of the snow melting panel are parallel to each other, so that the snow melting panel is installed. If the foundation is horizontal, the surfaces 73, 83 of the snow melting panel will also be horizontal, water after snow melting is difficult to drain, and if you want to make a slope on the surface of the snow melting panel to improve drainage, install the snow melting panel There is a problem that it is necessary to make a slope on the foundation to be built, which requires time and labor for the foundation work. Also, if the drainage is poor and the melted water is left on the snow melting panel, it may obstruct traffic,
The melted water penetrates into the foundation through the gaps between the snow melting panels, softening the ground and causing the snow melting panels to slip.

The snow melting panel of the present invention has been made in view of the above problems, and it is an object of the present invention to provide a snow melting panel having a good drainage property capable of promptly draining water after snow melting.

[0006]

The snow melting panel of the present invention comprises:
A heating pipe for passing a heating medium for heating a road surface or a heating element for heating a road surface is a snow melting panel embedded therein, and the surface of this snow melting panel or the bottom surface of a groove provided on the surface. Is an inclined surface.

In the snow melting panel of the present invention, in order to make the surface of the snow melting panel or the bottom surface of the groove provided on the surface an inclined surface, a means such as making a slope on the surface or the bottom surface of the groove can be used.

[0008]

In the snow melting panel of the present invention, a heating pipe for passing a heating medium for heating a road surface or a heating element for heating a road surface is buried in the snow melting panel. Since the surface of or the bottom of the groove provided on the surface is an inclined surface, the snow melted water is immediately discharged from the snow melting panel from the surface of the inclined surface or the bottom of the groove provided on the surface, No snowmelt water remains on the snowmelt panel.

As a result, it is not necessary to make a slope on the foundation on which the snow melting panel is installed, and it is possible to reduce the time and labor required for foundation work, laying work, and the like. In addition, since the snow-melted water can be immediately discharged to the outside of the snow-melting panel, the snow-melted water does not hinder the passage of the snow and facilitates the passage on the snow-melting panel. Further, since the melted water does not permeate into the foundation through the gaps between the snow melting panels, the ground does not become soft, and it is possible to prevent the occurrence of defects such as the displacement of the snow melting panels.
