JPH07217257A - Method for removing snow from roof - Google Patents

Abstract

PURPOSE:To allow separated snow to naturally slide down the slopes of a roof by its own weight to thus remove the snow from the roof at very low cost by attaching a heating element to the top of the roof, i.e., the joint between the slopes, melting the snow accumulating at the top with the heat of the heating element, and separating the snow to right and left. CONSTITUTION:A heating element 1 comprising a number of flattened insulators having heating wire or the like built in and joined together, is attached to the roof of a house. A current is passed through the heating element 1 to warm the insulator surface. The insulators are bonded to the top of the roof with an adhesive or the like. Also, one or several heating wires are attached directly to the top of the roof, or a pipe is installed in place of the heating wires and hot water or steam is allowed to pass through the pipe. Further, heating paint and insulating varnish are applied alternately to the top of the roof and a current is passed through the heating paint, or a material painted with the heating paint and the insulating varnish is affixed to the top of the roof.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for removing snow from a roof in a snowy area.

[0002]

2. Description of the Related Art Conventionally, the removal of snow from the roof of a house in a snowy area requires a lot of labor and is dangerous because the snow is mainly removed manually. Therefore, there is a method of melting the snow by installing heating equipment such as hot water on the entire roof, but this method is not practical because the equipment cost and maintenance cost are very high. Therefore, the applicant previously provided a triangular partition wall (2) projecting upward at the roof portion of the roof, that is, the joint portion between both slopes as shown in FIG. 5, to separate the snow accumulated on the roof portion. As a result, he later invented that the snow would naturally slide down the slope, and has already filed an application (Japanese Patent Application No. 2-55886).

[0003]

However, also in this method, since it is necessary to form a triangular partition wall and mount it on the roof, the mounting is difficult, the construction is troublesome, and the cost is high.

[0004]

[Means for Solving the Problems] If a heating element is installed in a strip shape on the roof of the roof, the snow accumulated on the roof can be melted and separated. , You can slide down the roof slope naturally due to the weight of snow. This method is much easier to install and less expensive than building a bulkhead and mounting it on the roof.

[0005]

[Operation] Next, the operation will be explained. The snow on the slope of the roof is relatively slippery, but the snow on the top is frozen and is difficult to separate right and left. And as it piles up, it becomes more and more frozen and hard to separate, so the snow on the entire roof will not fall. Therefore, if a triangular partition is provided on the top, the snow on the top will be separated into left and right parts, and as the weight of snow increases, it will naturally slide down the left and right slopes. Therefore, when snow falls to a certain extent, it naturally falls repeatedly, and it is not necessary to remove it. And, as a result of already implementing this, it has been confirmed that if the slope of the roof is 17 degrees or more, it will be effective by repeating natural fall with about 12 cm of snow.

Therefore, in the present invention, a heating element is provided instead of the partition wall. By arranging a heating element in the shape of a strip on the roof top, melting the snow accumulated on the top, separating the snow and sliding down the left and right slopes is exactly the same as when the partition wall was installed. Is.

[Embodiment] Here, the term "heating element" means, for example, a sheet made by incorporating a heating wire or the like into an insulator to form a belt by connecting a number of them and passing an electric current through it. Becomes warm. This may be attached to the roof top with an adhesive or the like. As another example, one to several heating wires,
It may be attached to the roof top as it is, or a pipe may be attached instead of the heating wire and hot water or steam may be passed through the pipe. Furthermore, the recently developed exothermic paint,
Insulation paint may be applied to the roof top and electric current may be applied to the heat-generating paint, or a product coated with heat-generating paint or insulating paint may be attached to the roof top.

As a first embodiment of the present invention, FIG. 1 shows a state in which a belt-shaped heating element (1) is attached to a roof of an ordinary house to form a belt by connecting a number of planar heating elements. As a second embodiment of the present invention, FIG. 2 shows a state in which a strip-shaped heating element (1) is also attached to the roof of the dormitory. Next, as a third embodiment of the present invention, a strip-shaped heating element may be attached to the kamaboko-shaped roof, but in FIG. 3, the strip-shaped heating element (1) is also attached to the top of the agricultural facility house. It shows the state of being. In this case, if a strip-shaped heating element is installed in the house on the back side of the top, it is possible to expect the effect of heat retention outside the snow and inside the house. If the band-shaped heating element (1) is shaped as shown in FIG. 4 in order to prevent the snowmelt water from flowing to the roof and freezing, the water will flow down through the gutter (3) to the ground. . In this case, a gutter may be separately attached to the belt-shaped heating element.

[0009]

INDUSTRIAL APPLICABILITY As described above, according to the present invention, roof snow removal work can be performed.
Since it was done manually by hand in the past, it required a lot of labor and there was a risk of falling, but by attaching a heating element to the roof top, the snow accumulated on the roof will melt and separate at the top part, As the slopes fall naturally, the snow can be removed from the roof at an extremely low cost.

Claims (1)

[Claims] 1. A roof top portion, that is, a joint portion of a slope,
A heating element (1) is attached, and the heat of the heating element melts the snow that accumulates on the top of the roof, separating the snow that has accumulated on the entire roof into left and right parts. The separated snow slides down the slope naturally due to its own weight. A method of removing snow from the roof, which is characterized by the above.
