Abstract

(57) Abstract: The present invention relates to a snow melting device for a road surface or a roof eaves portion using a planar heating element sheet. A roof snow melting device characterized by laying a sheet-like heating element sheet (1) at intersections, stairs, or roof eaves part A, which prevents falling due to snow sweeping labor or slippage and stops at the eaves. Melt the ice blocks to prevent damage from falling.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a snow melting device for a sidewalk surface, stairs, and roof eaves using a sheet of sheet heating.

[0002]

[Prior art]

 In snowy regions, dangerous accidents such as sidewalks, stairs, and intersections, etc., and sloping curbs are frozen, slippery, and fractured.

In addition, the snow on the roof loosens due to the increase in warm air due to heating in the house and the sunlight during the day, and the snow on the ridge loosens and slides toward the eaves. Then, snow falls again at night, and the repeated snowfall causes the snow to stop in the eaves, forming large ice cubes, causing the ice cubes to fall, damaging the equipment under the eaves, and sometimes causing personal injury. In addition, such ice blocks may be rolled up under the eaves, which may damage the gutter or break the window glass.

[0004]

[Problems to be solved by the device]

 For this reason, snow is swept and removed every day in the early morning when it snows, but frozen ice is slippery and cannot be removed by hoki or snow dump.

For snow on the roof, various snow stopping devices and snow melting devices have been devised in order to prevent the snow from falling, but simply stopping the snow is not necessary when there is a lot of snow, and the snow is also on the sidewalks and stairs. However, it has a drawback that the cost is too high when snow is melted by using a heater because the roof area is large.

[0006]

[Means for Solving the Problems] The present invention was developed in order to solve such problems of conventional snow sweeping on the road and snow on the roof. Considering the sheet, this heating element sheet is applied to the germination and seedling system for agriculture.

This planar heating element sheet is one in which a conductive heating paint layer is provided on a resin base film, the electrode wires are connected and power is supplied from a power source to generate heat, and the entire sheet is inserted into a waterproof bag. The heat generating sheet is used as waterproof plywood and laminated board B, or as a single sheet A provided at the eaves of the roof. This not only helps to melt snow on the road surface and stairs, but also prevents snow on the roof. It is designed to melt snow by turning on electricity when the ice blocks have solidified at the eaves.

[0008]

[Embodiment of the invention]

 An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a sectional view showing a sheet-shaped heating element sheet (1) laid on the roof eaves. FIG. 2 is a plan view of the sheet heating element sheet (1). FIG. 3 shows a cross-sectional view of the sheet heating element B in which the sheet heating sheet (1) is laminated on the lower surface of the waterproof plywood (2). FIG. 4 is an enlarged view.

[0009]

【Example】

 In FIG. 1A, A indicates a roof eaves tip. This roof shows a flat reed roof, but any reed roof can be used, and the sheet heating element sheet (1) is laid on the lower surface of the tin plate at the eaves. Further, the water resistant plywood (2) provided on the upper surface of the planar heating element B shown in FIG. 3 is provided with a V-shaped groove (3) in the width direction, which not only prevents slippage when laid. As it is rolled up and stored, it is convenient to carry and can be installed easily by simply rotating it.

Then, this heating element sheet is connected to a power source E through a temperature control box having a built-in thermostat.

Although not shown in the drawing, the eaves edge A for laying the surface heating element sheet (1) of the present invention for snow melting of the roof does not need to be provided all around the roof of the house, and particularly faces the road. It is preferable to lay it on the eaves of such a place, at the entrance of a doorway where people come and go, or at the eaves adjacent to the next house, and when using it on the road surface, lay it on the curb surface such as stairs and intersections. Often, laying in this way promotes power consumption and is economical.

[0012]

[Effect of the invention]

 As described above, the snow melting device using the sheet heating element sheet of the present invention does not impair the appearance of the roof by using the sheet heating element device as the heating element, and the damage caused by falling ice blocks Since it is possible to install it at a place or on a slippery place such as a sloping curb such as a floor or an intersection, the laying area can be reduced and an economical and remarkable effect can be expected.
