This fence contains supporting racks for installation around the perimeter of the enclosed area and a metal mesh cloth installed on the racks, as well as connecting elements and safety equipment, while the mesh cloth is made in the form of mesh panels connected from each other and sequentially stretched along the perimeter of galvanized steel wire whose intersecting rods are welded together.

The disadvantages of this technical solution:

1. The high cost of fencing mesh due to the hardening of its wire. At the same time, any hardening of the wire does not prevent its destruction by modern means: scissors with a hydraulic booster or a gas cutter.

2. Poor quality of galvanized coating due to improper choice of its thickness (maximum thickness is not limited) and a large percentage of unregulated impurities that impair the physical properties of the zinc coating.

3. The high cost of installation due to the tension of the nets.

The task of creating a utility model is to accelerate and simplify the installation process of the fence.

Achieved technical result: providing acceleration and simplification of the installation process of the fence due to the simplification of the design of the connecting elements, the refusal to weld and the ability to perform installation by one person.

The solution of these problems was achieved in a fence containing racks for installing a mesh fence around the perimeter of the enclosed area, consisting of mesh panels made of steel wire mounted on racks, as well as connecting elements, while the mesh panels are made in the form of interconnected intersecting rods, which are welded together while the connection of the mesh panels is made on racks by connecting elements, in that the connecting elements are made in the form of a wire or of wines comrade, under which the pressure plates are installed. The guard may be provided with an external anti-climbing device. The fence can be equipped with an external antirelapse and internal antirelapse devices. Wire spirals can be installed between the external and internal anti-climbing devices. Welded seams of the mesh panels can be facing the outside of the fence. The racks of the fence can be installed on the outside of the fence. Racks can be made of cold rolled sheet steel with a longitudinal weld. Racks can be made round in cross section. Racks can be made rectangular in cross section. Mesh panels can be installed directly on the ground. Mesh panels may be partially buried in the ground. With mesh clips, a protopod digging device can be attached to the mesh panels in the form of an additional mesh web partially buried in the ground. The undermining device can be made "G" -shaped in cross section. Reinforced concrete structures can be installed between the mesh panels and the ground.

The fence (Fig. 1 ... 20) is designed to protect the protected area 1 and contains mesh panels 2 mounted on racks 3 for installation around the perimeter of the protected area 1. Mesh panels 2 are made of steel wire, intersecting rods horizontal 2 and vertical 5 of which are welded between by means of welds 6 (Fig. 2). Mesh panels 2 are interconnected by connecting elements 7. Supports 3 are buried in the ground 8.

The cells of the mesh panels (Fig. 2) are vertical with the aspect ratio a / b = 2 ... 3. This range is optimal, since it allows you to reduce the weight of the mesh panel by 25% ... 30% and does not reduce its strength compared to a square cell.

After welding, the mesh panels 2 are galvanized by hot-dip galvanizing with an alloy containing from 97 to 99.5 zinc and the rest are additives that improve the physical properties of zinc. As such additives can be used copper, tin, etc. It is proved (Appendix 1) that some impurities in an amount of from 0.5% to 3% significantly improve the physical properties of zinc, mainly strength. The most effective supplements are magnesium and copper. The addition of 3% magnesium increases the strength of the coating by 3 times. The use of less than 0.5% of additives is ineffective.

The coating thickness is a value that provides the density of the zinc coating from 0.29 to 0.58 kg / m2. The large thickness of the zinc coating unnecessarily increases the cost of the mesh panel and does not increase its resource. The guaranteed resource of mesh panels 2 with the specified coating is more than 50 years. Racks 3 can be made in three versions (Fig. 4 ... 6).

In FIG. 4 shows a straight strut 3, in Fig. 5, a strut 3 has an extension 15 made at an angle from 100 to 170 degrees to the strut 3, and Fig. 6 shows a variant with a V-shaped extension 9.

Racks 3 are concreted in a concrete base 10 in the soil 9 (Fig. 7).

The fence can be equipped with an external anti-climbing device 11 (Fig. 7), or an internal anti-climbing device 11 (Fig. 8), or simultaneously with an external and internal anti-climbing device 11 with a spiral 12 installed between them (Fig. 9) or an Egoza tape. The mesh panel 2 may be equipped with an anti-trench device 13. (FIGS. 10 and 11). The undermining device 13 can be made in the form of a vertical additional grid (Fig. 10) or in the form of a "G" -shaped cross-section of the grid (Fig. 11).

Mesh panel 2 can be mounted on racks 3 using wire loops 14 (Fig. 11). In FIG. 13 shows the design of the plate clamp 19. In FIG. 14 shows a diagram of the fastening of the mesh panel 2 to the rack 3. In the rack 3, a plug 16 is installed (Fig. 14). The plug 16 may be made of plastic and hollow with a cavity 17 inside (Fig. 15)

The mesh panel 2 can be connected to the posts 3 by clamps 18 having bolts 19 and nuts 20 (Figs. 16 and 17

Welds 6 of the mesh panel 2 are facing the outside of the fence. Racks 3 fencing installed on the outside of the fence.

The coating of the mesh panel 2, as indicated earlier, is made with a density of zinc coating from 0.29 to 0.58 kg / m ² .

Racks 3 are made of cold rolled sheet steel with a longitudinal weld. Racks 3 are hot-dip galvanized with a zinc coating density of at least 0.29 to 0.58 kg / m ² and a zinc content of 97% to 99.5%.

The mesh panel 2 can be installed directly on the soil 8, or it can be partially buried in the soil 8, or to the mesh panel 2 with the help of the connecting brackets 24 an undermining device 21 is attached in the form of an additional mesh cloth partially buried in the soil 17. At the same time, the anti-aging device 21 may be attached to the mesh web 2 by means of connecting brackets 24 (FIG. 14)

The guard may be provided with an external anti-climbing device 18, as shown in FIG. 6 and 7, or the guard may be provided with an external anti-climbing device 11 and an internal anti-climbing device 11, as shown in FIG. 8 and also equipped with a spiral 13.

The fence can be equipped with safety equipment that responds to vibration and / or a video surveillance system.

Between the mesh panels 2 and the soil 8 can be installed reinforced concrete structures 23 (Fig. 20). This is usually not done on purpose, but the proposed fence is installed on top of an existing concrete fence.

The fence is mounted and operated as follows.

The marking of the site for the installation of fencing in straight sections of the perimeter is carried out using a conventional cord, stretched between the proposed installation points of the extreme racks of the site.

To determine the installation points of the racks 3, the entire rectilinear section is divided into segments 2.5 meters long, equal in length to one mesh panel 2 of the fence. The installation locations of the racks 3 are marked by 8 pegs driven into the ground.

In the places where the racks 3 are installed, using a drilling device with a diameter of 30 cm, soil is selected to a depth of at least 90 cm. Gravel must be added to the bottom of the pits so that the upper point of the rack 3 installed on it is at a distance of about 3 m from the ground.

The racks 3 mounted on gravel are poured with concrete mortar. Prior to the complete hardening of concrete, it is necessary to monitor the vertical position of the uprights 3 using a level with magnetic fastening, as well as the location of the uprights 3 strictly in one line in accordance with the marking.

Prior to the installation of the mesh panels 2 on the racks 3, it is necessary to first connect the mesh sections 2. using the fastening elements 7. The connection is overlapped by the size of two cells.

The mesh panels 2 are not stretched, as kA is used for fencing of large diameter wires from 3 to 9 mm and the pulling operation increases the cost of installation work.

In the same sequence, the entire fence is installed. In the case of fencing equipment with an anti-climbing device 11 and a spiral 13, they are mounted.

Reinforced concrete panels 23 or blocks of a previously installed concrete (reinforced concrete) fence can be installed under the mesh panels 2.

Small bumps in the terrain that could not be removed at the time of preparing the perimeter section can be compensated by trimming the mesh panel 2 from the bottom with a special cutting tool.

A properly installed fence should not have freely moving components relative to each other. Gusts of wind and light blows on the fence should not cause rattling of structural elements.

On the anti-climbing device 1, instead of a spiral 12, a reinforced barbed tape (of the “Egoza” type) can be installed.

Installation on the fence means of detecting the impact on the fence of the system elements that are part of the perimeter security alarm is carried out in accordance with the installation instructions of the system after the completion of the installation of the fence.

An external mesh sectional fence is designed to protect objects of various purposes from intruders, vehicles, domestic and wild animals.

Sectional fencing can be used in various options for constructing the physical strength system of an object, such as:

- external physical enclosure;

- a physical fence separating the exclusion zone from the inside or outside of the facility;

- a physical fence separating the internal regime zones from the rest of the facility;

- a physical fence equipped with perimeter detection equipment for any of the perimeter security lines.

Section fence can be used in different versions:

- external fence without anti-climbing device,

- external fence with anti-climbing device,

- external fence with anti-climbing device and a spiral,

- external fence with anti-trench device;

- external fencing with anti-climbing and anti-mine devices;

The option of the fence is selected based on the requirements of the customer and the possible directions for overcoming it by the likely intruder, the terrain and the location of the fence on the ground.

Installation of fencing can be carried out both directly on the ground, and on reinforced concrete structures that impede an attempt to undermine in order to penetrate the object.

The mounted guard that is put into operation consists of a structure 2.5–3.5 m high, consisting of a vertical part, and an anti-climbing V-shaped extension 9 from a spiral 11. To counter penetration of an object by digging under the guard, an anti-digging device 13 is used A distinctive feature of this type of fence due to the large thickness of the wire mesh fence - 3 ... 9 mm is the absence of the need for tension. This reduces installation time and cost of work.

To ensure the long-term operation of mesh panel fencing, all structural elements are galvanized with hot zinc.

During galvanizing, the mesh panel 2 is completely immersed in a bath of molten zinc. This operation is performed after welding the wire into a single mesh of section 2, as a result of the reaction, a zinc alloy is formed on the entire surface of the product, consisting of zinc 97 ... 99.5% and the rest is an impurity that improves the physical properties of zinc. This structure of the hot-dip galvanized surface provides excellent adhesion between steel and zinc, which no other paint, varnish, or metallized coating can provide, and at the same time, the relatively low cost of the galvanizing process.

The uniqueness of such a zinc coating lies in the fact that it creates not only an anti-corrosion barrier, but also provides electrochemical protection of steel. The specified thickness of the protective zinc layer being created significantly exceeds the parameters of other manufacturers.

Steel with such a thickness of the protective zinc layer can serve more than 50 ... 70 years without visible corrosion damage and renewal of the zinc coating.

The main characteristics of the welded mesh panels 2 fencing:

- The diameter of the wire mesh is 4.5 mm.

- The cell size is 50 × 200 mm.

- The density of the zinc coating is 0, kg / m ² .

- Zinc purity - 97 ... 99.5%.

- The tensile strength of the wire is not less than 800 MPa.

- The strength of the weld is 3200 N.

The strength of the bar, from which the welded mesh fence is made, does not allow biting the fence using improvised means.

The linear part of the fence during installation is stretched and overlapped on racks 3 or outside the racks 3. Welded lattice structures are facing the intruder, which makes it impossible to support for descent from the fence. Racks 3 are installed on the outside of the trellised fence to create additional obstacles for the intruder during the operation of the fence.

This fence is easier to install, reliable in operation, both from the point of view of its long-term readiness and from the point of view of functional reliability, since it eliminates the possibility of any quick overcoming of the fence and penetration into the protected area.

Application of the utility model allowed:

1. To provide acceleration and simplify the installation process of the fence due to the simplification of the design of the connecting elements, the rejection of welding and the ability to perform installation by one person.

2. Create a low-cost effective fencing and expanded the capabilities of the security system, which made it possible to detect the intruder.

3. To simplify the design of the racks, the accuracy of detecting effects on the grid is improved even with a single damage, the cost is reduced,

4. To simplify maintenance during its repair through the use of a collapsible joint.

5. Eliminate the variation in the parameters of the coverage of the grid and racks, which is due to the increased durability in difficult climatic conditions.

CJSC "INTEGRA-S" has developed a fencing scheme with elements of a security system in the form of a video surveillance system and software for a video surveillance system. The software is registered in FIPS.
