Description

The invention relates to the field of urban utilities, in particular to methods aimed at preventing the formation of ice and icicles on the roof of buildings.
The prior art device is used in the method of preventing the formation of icicles and ice on the roof of the building, selected as the closest analogue, providing for the installation along the perimeter of the roof of the heating element, combined with a drip, heated by passing electric current through the heating element, while the drip is made protruding beyond the edge of the pitched roof, the heating element is located inside the drip along its outer edge that extends beyond the pitched overhang effect, and the drip assembly carried on the inner side pitched roof (see. patent US №2699484, 1 Claim. (C1. 219-19), publ. 07 November, 1952 YG).
The tasks to be solved by the known device are: providing easy fastening to trim boards on the wall of the house, external accuracy, strengthening the roof structure, structural strength, ease of installation, structural simplicity and ease of manufacture, inexpensive to operate.
The upper part of the drip in the known device is located under the lower row of tiles, which is roofing material. In addition, the drip in the known device is positioned so that its angle of inclination coincides with the angle of inclination of the roof. The drip in the known device is fixed by flanging on edged boards that are attached to the side wall of the building. In addition, the heating element inside the drip is mounted on supporting elements to hold the heating element inside the drip at a distance from the walls of the drip. The material for the manufacture of the drip in the known device is galvanized iron, the thickness of which according to the standards is 0.5-2.5 mm.
The presence of elements such as flanging, edging boards, supporting elements, makes the known design is not simple enough, that is, complicates the design of the known device. And, at the same time, the presence of these elements complicates the installation of this device on a pitched roof and repair work. This is due to the fact that during the installation of a known device, many technological manipulations are required: installing a heating element on the supporting elements, attaching trim boards to the wall of the building, attaching the flanging to the trim boards. And when performing repair work, performing these manipulations in the reverse order. At the same time, the working space in which it is necessary to replace the heating element is insignificant, which makes it difficult to carry out repair work without removing the drip from the roof. In addition, if it is necessary to remove the drip from the roof, to replace it, it is necessary to remove the lower row of tiles fixed to the crate, for which it is necessary to provide an additional device to hold the upper rows of tiles, which were held by the lower row of tiles.
The implementation of the angle of the drip coincides with the angle of inclination of the roof, does not provide the ability to adjust the speed (frequency) of separation of the resulting drops of water when the roofs with different angles of inclination. This is due to the fact that it is well known that the greater the slope, the greater the speed of the water flow. Thus, the rate of water runoff on low-sloping (gently sloping) roofs is significantly lower than on high (steep) roofs. And since the separation of the droplet from the edge of the dropper directly depends on its mass (weight) (according to well-known information from the prior art), that is, on the amount and speed of water entering its formation, therefore, the frequency of separation of droplets from the edge of the dropper directly depends on the angle of inclination of the dropper . In this regard, the known device is advisable to apply only to steep roofs, that is, roofs with a large slope. Thus, the known device is ineffective for gently sloping roofs.
Use for the manufacture of a dropper of galvanized iron, the thickness of which is usually 0.5-2.5 mm, significantly reduces the thermal conductivity of the material of this device. It is well known that the heat transfer coefficient is inversely proportional to the wall thickness.
Thus, the technical result to which the claimed invention is directed is to create a method that uses to prevent the formation of icicles on the roof of a building a device that is much simpler in design and provides easier installation, more effective for any angle of inclination of the roof and has higher maintainability.
The specified technical result is achieved by the fact that in the method of preventing the formation of icicles on the edge of the pitched roof, the installation of a heating element along the perimeter of the roof, combined with a drip, heating when electric current is passed through the heating element, while the drip is made protruding beyond the edge of the pitched roof, heating the element is located inside the drip along its outer edge that extends beyond the pitched roof overhang, and the drip is mounted on the inside of the pitched roof, according to the invention, the installation of the drip is carried out by attaching it to the rafters, while the protruding part of the drip has an inclination angle different from the angle of inclination of the overhang of the roof, but not more than 30 degrees.
In this case, the drip is made of interconnected sheets of metal.
And for the manufacture of a drip metal is used with a thickness of 0.2 mm.
It is the installation of the drip by attaching it to the rafters and the protrusion of the drip with an angle different from the angle of inclination of the roof overhang, but not more than 30 degrees, as well as the implementation of the drip from interconnected sheets of metal or from a bent sheet of metal with a thickness of 0 , 2 mm allows to achieve the claimed technical result.
The design of the device used in the present method is much simpler than the device used in the closest analogue. This is due to the fact that the claimed method uses a device that excludes the presence of additional structural elements: trim boards, fasteners to these boards, flanging, support elements to keep the heating element at a distance from the dropper body.
It is the design of the device used in the claimed method, the installation of the drip by attaching it to the rafters, positioning it between the crate and the roof rafters of the building, helps to exclude these additional elements from the design. This is due to the fact that the attachment of the drip to the rafters provides it with sufficient holding power, without the need for additional fastenings to the wall.
It is the claimed design of the drip in the claimed invention and contributes to the simplification of its installation. This is due to the fact that the fastening of the drip on the rafters between the crate and the rafters in the claimed invention eliminates the need for additional technological transitions, it is enough to carry out one technological manipulation - fasten the drip on the rafters.
It is used in the claimed method, the device, its installation system and its design provide an improvement in its maintainability. Thus, the construction of the drip in the form of interconnected sheets of metal fastened together by any known method, makes it possible to simplify the repair of the drip on the roof and outside the roof. This is due to the fact that to remove the heating element from the cavity of the dropper, it is only necessary to disconnect the sheets of metal fastened together, access to which is not limited by anything, then insert a new heating element and re-fasten these sheets of metal to each other in any known manner. In this case, with such a drip, good accessibility to replaceable elements is ensured.
Mounting the drip at an angle different from the angle of inclination of the overhang of the roof, but not more than 30 degrees, contributes to a significant improvement in the efficiency of the method. It is this feature of the proposed method that allows you to select and set the angle of inclination of the protruding part of the drip, due to which it is possible to adjust the speed (frequency) of separation of the resulting water droplets taking into account the angle of inclination of the roof of the building. This is due to the fact that the greater the slope of the roof, the faster the water from melting snow will flow to the edge of the drip, where it will form into drops with a volume (weight) sufficient to detach from the edge of the drip. And since the separation of the droplet from the edge of the dropper directly depends on its mass (weight), that is, on the quantity and speed of water entering its formation, therefore, the frequency of separation of droplets from the edge of the dropper directly depends on the angle of inclination of the dropper.
The inventive method is illustrated by drawings. In FIG. 1 is a schematic diagram of the arrangement of the device used in the method. In FIG. 2 shows a diagram of the building structure and its pitched roof. In FIG. 3 is a schematic diagram of a drip structure (general top view and side view). In FIG. 4 is a cross section of a drip with a heating element placed inside it of two sheets of metal interconnected (Fig. 4). In FIG. 5 and 6 are possible cross-sectional views of a drip made of a bent sheet of metal, the use of which does not exclude the claimed method.
Along the perimeter of the edge of the pitched roof 1 of the building from the inner side of the eaves overhang of the roof, a drip 2 is installed. The drip 2 is a sheet of metal interconnected by any known method. The inventive method does not exclude the use of a dropper made of a bent sheet of metal. The cross section of the bend of the sheets can have a different configuration: U-shaped (Fig. 5), drop-shaped (Fig. 6), as well as V-shaped, C-shaped, U-shaped (not shown).
A heating element 3 is located inside the drip 2. The heating element 3 is located along the outer edge of the drip 2. The drip 2 is inserted between the crate 4 and the rafters 5 of the roof 1 of the building and attached to the rafters (rafters) so that it is located under the overhang of the roof covering material 1 on which there is snow cover or ice 6. When an electric current is passed through the heating element 2, the outer edge of the dropper 2 is also heated. The heated outer edge of the droplet 2 melts snow and ice and n in the form of drops 7 falls to the ground. The outer edge of drip 2 protrudes from under the overhang of the pitched roof beyond its limits by 5-200 mm.
The protruding part of the drip 2 has an angle of inclination different from the angle of inclination of the overhang of the roof 1, but not more than 30 degrees. The inventive method does not exclude its use and with the coincidence of the angle of inclination of the drip with the angle of inclination of the roof.
For the manufacture of drip 2 use a metal thickness of 0.2 mm As the heating element 3, a heating wire or cable of any known cross section is used.
On the drip 2 in the opposite side from the heating element 3 is a field “A” for attaching the drip 2 to the rafter system. Dropper 2 is equipped with leads for connection to a phase, zero 8 and ground wire 9. Protection from accidental or vandal interference with the electric heating element 3 is provided by the metal housing of the dropper 2. Bent or interconnected sheets of metal are connected using rivets 10 or bolts and nuts ( not indicated).
The device is connected to the mains through a residual current device (RCD) of 30 or 100 mA and galvanic isolation (not shown).
For greater aesthetics, drip 2 is painted to match the color of the roof.
Each drip 2 with a heating element 3 can be equipped with an electronic or mechanical temperature limiter to turn it off when the operating temperature limit is exceeded.
Used in the inventive method, the device is quite simply installed on existing objects using aerial platforms or crane means, without damaging the existing roof device. The installation of the device used in the claimed method does not require special skills and installation devices.
The method is as follows.
A voltage is applied to the heating element 3 placed by the inventive method, after which the heating surface, the edge of the protruding part of the drip 2, reaches a temperature higher than the ambient temperature by 20-50 °. Next, the heat is transferred by a contact method to the rest of the surface of the metal drip 2, and from it to the roof covering. Under the influence of heat, the snow begins to melt and slide to the edge of the cornice and then to the protruding part of the drip 2, on which it completely melts and flows down in the form of drops 7.
