Description

The solution relates to the field of construction, in particular to an anti-icing system for eaves of roofs and drainpipes, and is intended to prevent the formation of icicles on roofs and to save drainpipes from destruction when large pieces of ice fall in the pipe cavity.

Known invention, which relates to the field of construction, in particular to gutter systems. The technical result of the invention is to increase the rigidity of the drainage system. The gutter system contains gutters, each of which consists of a tray with sides curved inward, funnels for connecting the gutters to the drainpipes, and pressure clamps for fastening the pipes, as well as gutter suspension frames. Each of the frames includes mounting corners, lever holders, suspension arms, brackets and gutter holders. Moreover, each corner is made with holes on one shelf for installation on the roof rafters and with holes on the other shelf for bolting the flat lever holder, which is made with several groups of holes for interfacing with holes at one end and in the middle of the flat lever with the possibility of adjustment its angular position and the protrusion of the edge of the gutter beyond the roofing. At the other end of the lever there is a hole for connecting with a bolt with an elongated hole in the bracket having bent protrusions and holes for parallel mounting of the gutter holders made in the form of perforated L-shaped plates for interfacing with the sides of the gutter, while the gutters are made with a variable height of the tray, continuously changing along the length [1].

The invention relates to the construction, in particular, to the engineering equipment of buildings - to gutters equipped with anti-icing devices. The technical result of the invention is to reduce power consumption. The essence of the invention lies in the fact that a layer of heat-insulating material is applied to the drain funnel and drainpipe, and electric heating elements are placed directly on the outer surface of the drain funnel and drainpipe under a layer of heat-insulating material. In addition, at least one air valve is inserted into the drainpipe, overlapping the cross section of the drainpipe [2].

The invention is known, which relates to the field of construction, in particular to an anti-icing system for eaves of roofs and drainpipes, and is intended to prevent the formation of icicles on roofs and to save drainpipes from destruction when large pieces of ice fall in the pipe cavity. The technical result of the claimed invention is to ensure the safety of people by eliminating the conditions for the formation of ice and icicles of large mass that could cause injury, ensuring the safety of drainpipes from their separation and collapse as a result of freezing in cold weather and thawing (with a destructive fall of large fragments of ice) in thaw, as well as providing conditions for the impossibility of pasting announcements on the drainpipes and protection against hooligans, crushing pipes with blows of the feet. Prevention of the formation of icicles is achieved by using a garland with incandescent bulbs or with LEDs placed in a translucent sleeve mounted on the trajectory of falling drops of melt water. Instead of a garland, it is possible to use a double hose with a supply of warm air. It is proposed to use a reinforcing device to prevent the fall of large pieces of ice in order to preserve from destruction during the fall of large pieces of ice of drainpipes [3].

Known invention, which relates to the construction, in particular - to the gutters. The technical result of the invention is to prevent the formation of frost in the drainpipe in the winter-spring period. The drainage system contains sections connected to each other, in the upper part equipped with a water intake funnel, and in the lower part - with a drain tide. Inside the section along the entire length, a plastic sleeve made of a polymeric material is mounted, fixed with a bell. The narrow part of the bell is mounted on the sleeve, and the wide part is supported on the inner surface of the funnel, which is covered with waterproofing material [4].

The latest invention is closest to the claimed functionality and technical equipment.

However, the prototype, as well as the above analogues, has limitations in lightness, low adhesion with ice, elasticity and strength, fire safety. The objective of the proposed solution is to develop a drainage system designed for operation in any weather and climatic conditions, and the technical result is to increase the operational capabilities in terms of its lightness, low adhesion with ice, elasticity and strength, fire safety. A gutter system is proposed that contains sections connected to each other, equipped at the top with a water intake funnel, and at the bottom with a drain outlet, characterized in that it is made of at least one layer of wound or wrapped around the mandrel coating, contains made using the mandrel ( matrices) layers of fiberglass, on which a layer of the composition is applied as an impregnation, which is a mixture of resin and hardener, while the section, funnel, after curing and heat treatment is removed from the mandrel.

A method of manufacturing a gutter system, characterized in that the mandrel on which the sections are made and from which they are removed is made of an elastic and durable material, for example, an inflatable boat material, in the form of a hollow or solid cylindrical element or an element of a different section.

A method of manufacturing a gutter system, characterized in that the mandrel, on which the glass fabric is wound and from which the finished section or funnel is removed, is made of plastic or metal in the form of a hollow or solid cylindrical element or an element of a different section.

The section is wound on a mandrel, for example, with a diameter of 50 to 400 mm, a length of, for example, 2150 mm, onto which a glass cloth, for example, T-11 (92) silane, is applied by winding (on top of which a composite (mixture) is applied polyester resin, hardener, for example, butanox brand, colorant-pigment based on titanium, fire retardant paint, for example, the Terma-M brand. The specified composition at the rate of 1 running meter of the section contains: resin - 1.6 kg, pigment - 5 g, paint - 100 g, hardener - 16 ml. After drying the section blank for at least 20 minutes, granite crumb is applied in certain parts to it for anti-vandal performance. It should be noted that the mandrel, on which fiberglass is wound and from which the finished section is removed (possibly with a tint) or funnel, is made of plastic or metal mainly in the form of a hollow or solid cylindrical element; it is possible to use a mandrel of a different section, for example, square, depending on the task of manufacturing the pipe.

It is possible to apply the specified composition to the mandrel from an elastic material by pultrusion — continuous drawing of glass-material impregnated with resin through a forming die.

Figure 1 shows the deposition (mainly winding) on the mandrel (matrix) 1 of a fiberglass 2; after impregnation of the applied layers with resin with a hardener and, if necessary, other materials, curing and heat treatment and removal from the mandrel, section 3 is obtained. FIG. 2 shows sections of the drainage system 1800 mm and 900 mm and a width of 216 mm, respectively, in FIG. 3 branch section, bent at 135 degrees, figure 4 - section with ebb, bent at 135 degrees, figure 5 - adapter section with a funnel of 370 mm in the upper part and 216 mm in the lower part.

The mandrel can be made of inflatable boat material: rubberized fabric, PVC, elastic fabric, etc.

In relation to the drainage system, a section made of the specified composite material can meet the parameters according to GOST 7623-84 (Downpipes. Technical conditions): diameter 216 mm, section length 1250 mm, branch 45 degrees, funnel diameter 370 mm.

A gutter system made in this way has the following properties:

- lightness (4 times lighter than an analogue of steel, which allows mounting on the ground; an assembled system of 20 mp weighs no more than 15 kg; one-piece section connections allow one person to lift the entire system from the roof);

- reliability of the connection sections due to the installation of its components under the cone;

- to fasten the system to the 20-meter building facade, two times less anchors with clamps are required than the existing system (there, for each link, one clamp with one anchor for every 1250 mm is needed);

- ice does not build up on the inner walls of the sections, low adhesion to ice;

- the elasticity of the system (avoids jamming of both the lower section with the ebb and the funnel under mechanical action on them; the trunk of the drainage system has high compressive elasticity and is able to withstand repeated deformations without changing the original shape);

- visually the system looks absolutely straight, without joints and seams;

- the life of the system with exposure to mechanical stress and weather conditions more than 5 years;

- operating temperature range from -60 degrees Celsius to +120 degrees Celsius;

- maintainability: the system is easily repairable, without replacement with new sections, without dismantling the trunk;

- fire classification - self-extinguishing;

- the system is not subject to corrosion;

- reduction in transportation and installation costs; significantly reduces the risk of falling components and elements of the drain from a height, which leads to accidents and property damage;

- due to the impossibility of ice formation inside the drain, there is no need to use a heating cable; the trunk of the system always remains free, which leads to a decrease in the formation of icicles on the water intake funnel and on the overhangs of the roof in the autumn-winter period;

- along with the anti-vandal performance of the pipe by sprinkling it, for example, with marble or granite chips, with a fraction, for example, 0.2-5 mm, it is impossible to apply various stickers in the form of announcements, leaflets, etc.

- resistance to ultraviolet radiation.

The installation of the trunk of the drainage system is carried out as follows: the upper section descending onto the cone is inserted into the socket of the lower section, a strong connection is obtained with the possibility of one-piece connection; other sections may also be connected, for example by gluing, welding, riveting, etc. This solution seems possible to use in a number of industries where parameters and properties of the claimed solution are required.
