Abstract

The utility model relates to the field of construction and public utilities, in particular to the design of an anti-icing cornice for a pitched steel or slate roof.

The anti-icing cornice of the pitched roof is made of heat-conducting sheet material attached to the roof. At the same time, the part of the eaves protruding from under the roof is made more than 120 mm wide and bent down along the edge of the roof at an angle of 10÷30 degrees from the vertical plane passing through the edge of the roof, and covered with matte black paint. Additionally, between the roof and the eaves, a gasket made of non-thermal conductive material can be installed.

The technical result consists in preventing the formation of ice on the eaves of a pitched roof. 1 z.p. f-ly, 2 ill.

Description

The utility model relates to the field of construction and public utilities, in particular to the design of an anti-icing cornice for a pitched steel or slate roof, which is exposed to sunlight during the day.

Closest to the proposed device in terms of technical solution is anti-icing eaves of a pitched roof, equipped with electric heating elements and made of heat-conducting sheet material attached to the roof (see US Pat. US 5391858 C, 1995).

The disadvantages of this solution are the complexity of the design, the high cost of structural elements, high energy costs, fire hazard.

The technical task of the proposed solution is to simplify the device, reduce the cost of manufacturing, installation and maintenance, expand the arsenal of technical means, and increase security.

For this purpose, an anti-icing cornice of a pitched roof is proposed, made of a heat-conducting sheet material attached to the roof, and the part of the cornice protruding from under the roof is more than 120 mm wide and is bent along the edge of the roof down at an angle of 10-30 degrees from the vertical plane passing through the edge of the roof and covered with matte black paint.

A distinctive feature of the proposed device is that the part of the eaves protruding from under the roof is more than 120 mm wide and is bent along the edge of the roof down at an angle of 10-30 degrees from the vertical plane passing through the edge of the roof and covered with matte black paint.

The essence of the proposed device is illustrated by the drawing, where in Fig. 1 shows a section of the proposed device, Fig. 2 view of a prototype anti-icing eaves.

The anti-icing cornice of a pitched roof is made of heat-conducting sheet material attached to the roof 1. Part 2 of the cornice protruding from under the roof is made with a width L of more than 120 mm and is bent along the edge 3 of the roof down at an angle a equal to 10÷30 degrees from the vertical plane 4 extending over the edge of the roof away from the edge of the roof and finished in matt black. Between the roof 1 and the cornice 2 there are gaskets 5 made of non-thermal-conductive material (asbestos or fiberglass). The cornice is attached to the roof 1 with rivets.

The proposed device works as follows.

At positive air temperatures, under a layer of snow lying on the roof, melt water appears, which rolls down the roof 1 and along the cornice 2. When it gets cold, the water freezes at the lower edge of the cornice, forming an icicle germ. In the proposed device, under the action of sunlight, the surface of part 2 of the cornice is heated to a positive temperature, since the cornice is made of a heat-conducting material and its plane is inclined at an angle of 10 ÷ 30 degrees, then the heating from the sun's rays is more intense. The inclination at an angle of 10-30 degrees allows the sun's rays to be closer to the part of the eaves 2 perpendicular to the plane. With a cornice width of more than 120 mm, the heat from the sun's rays is enough for the icicle embryo to break away from the cornice without gaining a large mass or not formed at all. The melting rate is increased by painting the eaves with matt black paint. Thus, the claimed design independently gets rid of small icicles. In addition, to exclude the process of cooling part 2 of the cornice from snow located on the roof, gaskets made of non-heat-conducting material can be installed between the roof and the cornice. The absence of heating devices ensures the safety of the structure.

The absence of massive icicles on the anti-icing cornice prevents the formation of ice on the edge of the cornice, to which melted wet snow usually sticks. This prevents the formation of icy blocks of snow, which often hang on the edge of the roof with a conventional cornice and cause an avalanche of ice from the roof.

Tests of a prototype device showed the simplicity and efficiency of the proposed design. In the prototype of the device for painting, universal enamel KUDO black matte (RAL 9005) 1/12KU-1102 was used.
