Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to a snow eave prevention method that can prevent snow eaves, rolls, etc. formed by snow on a flat roof or a parapet on the leeward side of a building with a parapet. This relates to attached buildings.

[Conventional technology]

Buildings with parapet roofs in the Tohoku region simply formed a parapet, with a kasagi attached to the top. Furthermore, as a method of forcibly preventing snow eaves, there is a configuration using electric heating, but this method has the disadvantage of high running costs and lack of economic efficiency.

[Problem that the invention seeks to solve]

In buildings with this kind of structure, the snow in the Tohoku region is sticky, so a snow eave B is formed on the leeward side of the rosette A as shown in Figure 2, and large rolling sag occurs, causing this snow eave B to break. When it falls as a snow mass, it collides with the exterior wall C1 window, which has the disadvantage of destroying or deforming the exterior wall material and glass window.

In addition, this snow canopy could be life-threatening if it fell on a person passing by.

[Means for solving problems]

In order to eliminate these drawbacks, the present invention ventilates indoor warm air through at least the leeward side parapet, installs a mountain-shaped cap on the top surface, and furthermore covers the south side of the parapet with a heat insulating layer to create a snow eaves. In addition to preventing the destruction and deformation of exterior walls and windows, the building completely eliminates the danger to people passing by near the road, and it is also possible to utilize waste heat, which is highly economical. This provides a building with snow eaves protection.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a building with snow eaves prevention according to the present invention will be described in detail below with reference to the drawings. That is, the present invention directs indoor warm air to the cap through an insulated ventilation path formed in the rose bed, melts the snow that accumulates on the cap, and prevents large amounts of snow from blowing into the leeward side into large clumps (snow eaves). )
It is designed to cut off the snow eaves before it becomes so-called snow eaves. To explain specifically, in Figure 1,
1 is the roof, I is parabet, 4 is the ventilation path, 5 is the insulation material,
6 is an exterior material, 7 is a cap, 8 is a ceiling formed into a heat insulating structure, 9 is an indoor room, and 10 is a warm air. To explain further, the ventilation path 4 utilizes the rise of warm air 10 in the room 9 to blow it onto the cap 7 attached to the top surface 2a of the rose pet I, and uses this warm air 10 to melt the snow on the cap 7. be. Also,
The insulating material 5 covers the inside and outside of the rosette, prevents the temperature of the warm air 10 from decreasing, and melts snow more efficiently.The material is one or more of plastic foam, glass wool, rock wool, etc. It consists of Further, the exterior material 6 is made of one of metal plates, mortar walls, ceramic siding materials, ALC boards, bricks, plywood, etc., and can be made singly or with plastic foam integrally formed thereon. In addition, in FIG. 1, the inner and outer walls of the detacher l-2 are shown using a building material in which a heat insulating material 5, an exterior material 6, and an interior material 11 are integrally formed. In addition, Kasagi 7 has warm air 1 on the top surface 2a of parapet λ.
It is installed in a way that prevents too much snow from leaking, and it is also formed into a mountain shape so that snow can easily fall off.

Next, a comparison between Examples and Comparative Examples is as follows. The heat insulating material 5 is polyurethane foam (thickness: 25 cm, density: 30 kg/n?), the exterior material 6 is a gutter-like body with male and female connecting parts of colored steel plates (thickness: 0.27 mm), and the interior material 1
2, a sheet made of aluminum foil and asbestos paper is integrally formed and fixed onto the frame of the parapet 1 with nails (not shown). In addition, the Kasagi 7 is a colored steel plate (thickness 0.35 m5) formed with θ = 90°, the hollow part dimension of the ventilation passage 4 is t =], about Qcm,
The depth shall be the length of the rose pet. In addition, warm air 10 is 20°
Let it be C. On the other hand, in the comparative example, the parapet I has neither a heat insulation structure nor a ventilation passage, and the cap is simply a flat type with a slightly inclined structure. Therefore, if the snow accumulates around 50CI11 in one day and the wind is 15m/+im, there will be almost no snow on Kasagi 7 of Barapet 1 on the leeward side of the building shown in Figure 1, and there will be no snow on Kasagi 7 on the roof ■1. As shown by the dotted chain line, snow 12 had accumulated in the form of snowdrifts. On the other hand, in the comparative example, as shown in FIG. 2, the snow eaves B were gradually formed, and when the snow eaves broke, the above-mentioned drawbacks and disadvantages occurred.

〔Effect of the invention〕

As described above, according to the building with snow eaves prevention according to the present invention,
Snow eaves do not form on the paravets, they do not destroy or deform the exterior walls and windows of the building, and they do not pose a danger to people passing directly under the building, and are economically efficient. It also has the feature of requiring no running costs and making effective use of the warm air exhausted indoors.
