Description

[Detailed description of the invention] << Industrial application field >> The invention relates to an unwinding prevention device for preventing a building from being damaged by ice and snow lump with icicles hanging from an eave of the building in a snowy cold region.

<< Prior Art >> Snow on the roof of a cold region often causes a phenomenon of rolling as shown in FIG. The snow cover 2 of the sloping roof 1 slides on the roof surface, hangs downward from the tip of the eaves 3 in a tongue-like semi-frozen state (ice and snow mass including icicles), and further develops by bending inward (toward the building). This curl is more likely to have a north-facing roof than the southern side, and depending on the weather conditions, it can have a well-developed curl, eaves, gutters, windows, outer walls 4
May be damaged by unwinding.

In order to prevent the building from being damaged by the unwinding, Japanese Utility Model Laid-Open No. 55-31933 discloses the following ice melting structure. In this prior art, an electric heater is disposed in a vertical blast area located inside the tip of the eaves.

<< Problems to be Solved by the Invention >> In the related art in which the electric heater is provided in the gable part as described above, the icicles and unwinding itself are prevented directly under the tip of the roof. Therefore, it is difficult to melt the unwinding effectively with a small-scale electric heater.

The present invention has been made in view of the above-described conventional problems, and its purpose is to prevent icicles themselves from occurring to some extent, but to prevent them from developing and becoming untangled with small-scale equipment. .

<< Means for Solving the Problems >> In the present invention, therefore, a hanging plate extending substantially vertically downward is continuously provided at the tip of the eave, and the lower end edge of the hanging plate is bent inward and upward, and the valley of the bent portion is formed. The heating wire was arranged inside the.

<< Effect >> The icicles and undulations develop while the water gradually freezes at the tip of the eaves, but in the unwinding prevention device of the present invention, the hanging plate is provided continuously from the tip of the eaves. Therefore, the hanging plate becomes the icicle generation site, but the heating wire is provided at the lower end of this portion, and freezing of water does not occur here.

<< Embodiment >> FIG. 1 shows a schematic configuration of an unwind prevention device according to an embodiment of the present invention. In the figure, 1 is a sloping roof, 3
Is an eave that projects out of the outer wall 5 at the same inclination as the roof 1. The roof 1 and the eaves 3 have a double structure of a heat insulating material 6 and a waterproof material 7. In order to mount the unwinding prevention device of the present invention, sheet metal support plates 8 are attached to the outer wall 5 below the eaves along the eaves 3 at appropriate intervals, and the support plate 8 is used as a support to mount the unwind prevention plate 9 to the eaves. 3 and the whole is fixed with a stopper 10.

The unwinding prevention plate 9 is made of a stainless steel plate, and is steeply connected to the tip of the eaves 3 at the tip of the eaves 3 to steeply slope from the eaves 3. It has a plate 9b and a bent portion 9c formed by bending the lower edge of the hanging plate 9b inward and upward at an angle of about 45 degrees.
The heating wire 11 is provided in a valley-shaped portion formed by the hanging plate 9b and the bent portion 9c. The roof 1 and eaves 3
Of the waterproof material 7 extends to the steeply inclined plate 9a of the unwind prevention plate 9.

In the above configuration, the snow accumulated on the roof 1, the eaves 3, and the steeply inclined plate 9a is partially melted, and while the water slowly flows down along the hanging plate 9b, the ice freezes at the portion of the hanging plate 9b to cause icicles. However, a bent portion is formed inside the lower edge of the hanging plate 9b.
9c is formed, and the heating wire 11 is disposed inside the valley of the bent portion 9c, so if the heating wire 11 is energized, even a small amount of heat generation prevents the formation of unwinding And the occurrence of unwinding itself can be prevented.

In addition, since the bent portion 9c is directed upward, there is no possibility that the icicles are horizontally guided by the surface tension of the water and become undulated.

<< Effects of the Invention >> As described in detail above, in the unwinding prevention device according to the invention, a small amount of water supplied by melting a part of the snow on the roof is frozen again at the eaves, and the icicles generated by the icicles are generated. Can be prevented by the heating wire provided in the part that becomes unwound as it develops, so it is possible to effectively prevent the occurrence of unwinding itself with a small amount of heat generation, and part of the building by the unwinding No damage.
