DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow sliding device improved so that snow does not accumulate on a roof.

[0002]

2. Description of the Related Art Conventionally, as roofing materials for roofing, there are a roofing material formed by hardening clay in a certain shape and baking in a tile kiln and a metal roofing material made of various metals.

However, when the conventional roofing material as described above is used, for example, in a snowy country, snow is piled on it in winter and it cannot be expected that the snow will naturally slide.

[0004] For this reason, snow falling on the roofs of ordinary houses and large buildings must be removed, which requires a great deal of labor and cost, and the danger and damage to human property and property is thereby reduced. unfathomable. The measures to overcome the snowfall are also considered as important issues by the administrative authorities.

[0005] As a countermeasure against such a problem, a forced snow melting apparatus such as a boiler type roof snow melting apparatus, a heat pump snow melting apparatus, an electrothermal snow melting apparatus or the like is generally known. These have the advantage that there is no need for post-processing since the snow is melted and flowed, but there is a problem that equipment costs, heat sources, running costs such as maintenance are required, and the burden is large.

[0006] Therefore, as shown in Japanese Patent Application No. 4-333057, titanium is coated on the surface of a metal base material formed into a metal roofing material by an ion plating method to thereby provide excellent corrosion resistance. A metal roofing material having characteristics such as low thermal conductivity, high electrical resistivity and high hardness has been proposed, and the accumulated snow naturally slides due to these various characteristics, so that it is not necessary to perform operations such as snow removal.

[0007] In the metal roofing material coated with titanium as described above, in the case of snowy material containing much moisture, for example, snow falling in Niigata, Hokuriku region, etc., naturally snows even if the outside temperature is -1 ° C or less. .

[0008]

However, even in the case of a metal roofing material coated with titanium as described above, in the case of so-called powder snow, which has relatively little moisture, when the outside air temperature is -5.degree. C. to -2.degree. There was a problem that it was difficult.

In view of the above, the present invention has been made to solve the above-mentioned problem, and it is possible to surely slide snow on a roof by heating the metal roofing material even under weather conditions in which snow does not easily slide. It is an object of the present invention to provide a snow-sliding device capable of reducing the cost.

According to the present invention, even when powder snow is deposited on the roof, by heating the titanium-coated metal roof material, the roof material has excellent corrosion resistance, low thermal conductivity, and low hardness. Due to the synergistic effect of the high properties and the warming, natural snow sliding can be ensured.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of a snow sliding apparatus according to the present invention.

FIG. 1 is a schematic view showing one embodiment of a snow sliding apparatus according to the present invention, and FIG. 2 is an enlarged view of a cross section taken along line AA of FIG. Reference numeral 1 denotes a metal roofing material, which is obtained by rolling an aluminum material, a stainless steel material, or the like and cutting it to a predetermined size to form a metal base material 11 and coating the surface thereof with titanium 10 by an ion plating method. It is.

The method of coating titanium by the ion plating method is disclosed in Japanese Patent Application No. 4-333057, which is described in detail there.

Reference numerals 2a and 2b denote electrodes attached to the metal roofing material 1, reference numeral 4 denotes an electric wire, and reference numeral 3 denotes a transformer for applying an appropriate voltage to the metal roofing material 1.

Reference numeral 5 denotes an earth leakage breaker with overcurrent protection for preventing an earth leakage accident, and has a sensitivity current of 30 mA or less. Reference numeral 6 denotes a roofing base material.

Next, the construction will be described. Although not shown, a waterproof sheet is usually laid on the base material 6, and a metal roofing material 1 is used on the waterproof sheet in the same manner as in the usual case. The roof is covered with. At this time, the portions where the metal roofing materials 1 overlap each other are subjected to a waterproof treatment or the like with a conductive sealing agent.

The electrodes 2a, 2b are attached to the left and right ends of the metal roofing material 1 thus laid, and the electric wires 4 attached to the electrodes 2a, 2b are connected to the secondary side of the transformer 3. ing. The temporary side of the transformer 3 is connected to AC100V via an earth leakage breaker 5 with overcurrent protection. Further, a third-class grounding work is performed, and the ground wire is connected to the earth leakage breaker 5 with overcurrent protection so as to prevent an earth leakage accident.

When the power is turned on, the AC 100 V is reduced to an appropriate voltage by the transformer 3 and applied to the metal roofing material 1 via the electric wires 4 and the electrodes 2a and 2b. Due to its high electrical resistivity, it generates heat by itself and the entire metal roof is uniformly heated.

By inserting a thermostat or the like between the base material 6 and the metal roof material 1 and turning on and off the secondary side circuit by the output thereof, the surface temperature of the entire metal roof is reduced to 0 ° C. to 2 ° C. It can also be controlled so that

Therefore, even if powdered snow with little moisture is deposited on the metal-coated roofing material 1 coated with titanium by heating the metal-based roofing material 1 by the simple heat assisting means as described above, the metal-coated roofing material 1 can be applied to the titanium-coated surface. As the snow in contact with the metal roof material 1 is melted, the accumulated snow is surely successively slid down to fall down due to a synergistic effect with the above-mentioned various characteristics of the metal roofing material 1.
