Description

The proposed utility model, hereinafter the device, relates to physical engineering barriers, namely, metal lattice barriers, and can be used in the national economy in the construction of mechanical barriers to protect objects from unauthorized access to their territory of individuals, equipment, animals.

Known engineering obstruction - the barrage of mods. "ZGR-125" BZHAK 425729.001 Research and Development Institute of Radio Engineering - NIKERET, Zarechny, Penza region. (a photocopy of the 17th sheet of the operating manual BZHAK425729.001RE - A4 format is attached), containing the supporting part, made in the form of uprights (supports) installed in the ground, and a canvas fixed to the supporting part. The racks are made integral, telescopic, the upper part enters the lower and is fixed in it. The canvas is made of welded galvanized wire mesh and also consists of two parts connected to each other by a rigid connection.

The known device has disadvantages.

The racks are made of components of different sizes of channel profiles with the use of fasteners, which reduces the reliability and rigidity of the bearing part of the device, since the joints during use for their intended purpose (fasteners) are loosened from various factors, including natural ones, backlashes and gaps are formed, and the whole fence can swing and creak.

The canvas, stretched on the bearing part of the device - on the racks and the supporting wire, during operation “sags”, that is, it receives plastic tensile deformations and lengthens under the influence of various factors -

winds, snowfall, fallen tree, own weight. In this case, the vibration amplitude of the web increases. The fence, including this device, loses rigidity, becomes easily overcome, therefore, its reliability is reduced. In addition, this drawback involves the systematic tension of the canvas in order to restore the original length, which is very time-consuming or even ruinous for long fence lengths.

The canvas is easily overcome, since it does not contain prickly elements, and, because of this, is also unreliable.

Known engineering barrage device manufactured by the company "DIRICKX" (France) - modification of Tigre, (see the catalog of the company "DIRICKX GROUPE", publ. DIRICKX sas - 53800 CONGRIER-FRANCE, July 2003, p. 100, photocopy of the page - 1 sheet of A4 format (attached), containing the supporting part and the canvas. The supporting part is made in the form of pipes from racks. Brackets are fixed on the racks, the threads of the carrying wire are stretched on them. The canvas consists of a combination of a flat component made of steel woven mesh installed on racks, and two spiral safety barriers mounted on the carrier part, with one barrier mounted on the brackets and the carrier wire on top of the device, the second is located on the outside of the fence and is connected to the uprights and the net.

However, the known device has disadvantages.

The presence of brackets and a supporting wire on them makes the structure heavier, requires fasteners for their fastening on the racks or welding the brackets themselves to the racks. The first leads to the appearance of gaps in the joints during operation, for example, from winds, loosening of the structure, which involves additional time spent on tightening the joints. The second - destroys the coating, requires additional costs for cleaning the welds, restoration of the coating.

Both that and another - the factors testifying to low reliability and rigidity of the known device.

The canvas is made of a simple mesh, and not of barbed tape, which significantly reduces the protective properties of the device.

In addition, the prickly and impregnable spiral security barrier on top of the fence is completely inadequate to the non-spiked canvas on the middle of the fence, which is most susceptible to attempts to overcome. At this point, the canvas is easily overcome with the help of a conventional staircase (or curbstone) and nippers. The specified feature also indicates the low reliability of the known solutions.

The safety barrier is spiral, located on the outside and at the bottom of the device, it is easy to dismantle it and leave the lower part of the barrier unprotected from outside penetration. This factor also indicates the low barrage qualities and low reliability of the known device.

A device of the company RABAN P.H.U. is known. (Poland), 61-558 Poznan ul. Wierzbiecice 37A \ 7, FAX: + 4861833-1999 - (two sheets of A4 format COCHRANE PRODUCTS brochure attached), consisting of a supporting part containing racks buried in the ground and canvas. At the same time, rows of carrier wire are stretched over the racks. The canvas is designed in the form of a rhombic grid of pieces (segments) of barbed reinforced tape (LCA), overlapped, rigidly fastened at their crosshairs with each other, and located by the plane of the tape along the front.

This device has disadvantages.

The canvas is mounted on the supporting part, uprights, directly without the frame. Because of this, its deflection is significant from the influence of natural factors and its own weight, low stiffness, excessive amplitude of the canvas vibrations. The barrier is made of a barbed tape reinforced in the form of a rhombic grid, which is located in the device with its plane along

front and is also connected along planes at the crosshairs of the overlap rows with rigid joints. Welding or plastic deformation (indentation) over the nodes destroys the coating, for example, it is extremely time-consuming to restore the coating after welding, especially zinc. The binding of strips of tape overlapping, nodes knitting wire or stapling instead of welding will not provide sufficient rigidity of the fabric. These features indicate the high complexity of manufacturing the device and its low reliability and rigidity. The device is easily overcome, since its spikes are directed inward, and the outer, front sides are devoid of protection.

The execution of the canvas with the arrangement of the parts of the tape with their planes parallel to the front is extremely difficult to manufacture. The canvas is stubborn - this drawback manifests itself especially when mounting the device on rough terrain, when it is necessary to compensate for deviations in the positioning of the racks with the blade - the blade swells, which worsens the appearance and requires restoration.

The result of the implementation of this utility model is the achievement of a technical result - increasing reliability and rigidity while reducing the cost of manufacturing and maintaining the device; at the same time - increase the barrage properties of the device.

The proposed device eliminates the listed disadvantages of the known solutions and allows to achieve the intended technical result. In addition, it applies to a whole group of similar devices having in their design a complete (or partial) set of significant differences characteristic of the claimed device, and allowing to achieve the claimed technical result.

In the proposed device, containing a bearing part, consisting of uprights, buried in the ground, and a canvas fixed to the bearing part, while the bearing part is equipped with an additional rigid rectangular

frames made of rolled steel, the sheet is made of a flat safety barrier “Acacia”, consisting of a barbed reinforced tape (LKA), located in it in the form of a rhombic grid, formed by stripes of tape in the form of a sinusoid, facing each other with vertices and rigidly connected in places touching adjacent strips, with the location of the common outer plane of the cutting part - the edges of the tape along the front, is fixedly mounted on the frames with the excess of their sizes on top and bottom and the formation of additional protective barriers and together with the frames mounted on racks.

Supplying the device with additional rigid rectangular frames with a web stretched over them - the Akatsia flat security barrier, consisting of reinforced barbed tape installed in it in the form of a rhombic grid with cells formed by stripes of tape, in the form of a sinusoid, with hard peaks facing each other communication in places of contact of neighboring peaks, increases its reliability and rigidity, reduces the complexity of manufacturing.

The location of the canvas on the framework with the ends of the barbed reinforced tape protruding at the top and bottom of the frame increases the protective properties of the device and makes it more reliable. Installing the canvas on the racks through the frames significantly increases the reliability and rigidity of the device. Rigid installation of frames with a cloth on the racks provides increased device resistance to the influence of force factors, improves its consumer qualities, improves appearance.

The use in the design of the device of a cloth made of a safety barrier flat “Acacia”, consisting of reinforced barbed tape located in it in the form of a rhombic grid, formed by stripes of tape in the form of a sinusoid and facing each other peaks with a rigid connection in places where the adjacent bands touch, the location of the strip of tape with its outer edge of the cutting part along the front, the location of the blade on the frame with the protruding ends of the tape

on top and bottom of the frame, - a set of features that can improve the reliability and rigidity of the device, its protective properties, resistance to external forces, give it properties that are not found in known devices. This allows us to conclude that the proposed device meets the criterion of "novelty."

Supply of the device’s bearing part with rigid rectangular frames, fabrication of the fabric from the Akacia flat security barrier, consisting of LCA woven in the form of a rhombic mesh, located in the barrier with the outer edges of its cutting parts along the front, installing the fabric on a rigid frame with the formation of additional protection barriers - of two rows of the ends of the barbed reinforced tape protruding from below and above and the rigid installation of the frames with the canvas on the racks by means of trims - indicates significant differences we offer oh device from the prototype, allowing to achieve the intended technical result.

In the proposed device, presented on one sheet f.A4, shows:

- Fig. 1 is a general view of the device, Fig. 2 is a side view of Fig. 1, Fig. 3 is a cross-section A-A in Fig. 1 on an enlarged scale (the scales are arbitrary), illustrating the scheme of binding adjacent bands (at the vertices sinusoids), the position of the tape when bonding along the plane - in and the common plane of the ribs - g, figure 4 - shows a fragment of a General view of the LCA, figure 5 is a side view of figure 4, indicating the planes b and g.

The device shown in the drawing covers all varieties of similar devices having similar properties in design and location on the supporting part.

The drawing shows the load-bearing part in the form of uprights 1, buried in the ground, and a web 2 installed on them. The canvas is made by interlacing from segments of a barbed reinforced tape 3 in the form of a sinusoid, the vertices 3a and 3b facing each other connected rigidly at the points of contact,

for example, knitting wire 4 and located on the frame 5 in the form of a rhombic grid. Thorny elements of the tape are directed by their outer ribs (g) to the frontal plane of the canvas. The canvas is located on the frame with the protruding ends 6 and 7 of the tape 3, respectively, on top and bottom of the frame. The canvas is fixed on the frame, for example, with brackets 8 and wire 4. The frames 5 together with the web 2 are rigidly mounted on the posts 1, for example, are welded by means of strips 9. The configuration of the “diamond” is conditional, since it only resembles this figure, in fact, its sides they have curvature at the vertices associated with the method of manufacturing the canvas and characteristic of the "sinusoid". The rhombus has dimensions - height H and length L. Thus, the step t of the rhombic web is equal to the length of the rhombus t = L. The geometric parameters of the safety barrier of the flat "Acacia" are characterized by the dimensions of the rhombus.

The intended use of the device (operation) occurs in the following order.

Sections of the device, each, for example, with a length of 3000 mm, are mounted in one circuit (chain) with a base length conventionally adopted 250,000 mm, is not shown in the drawing. (A section is a part of a device consisting of one rack and a web rigidly mounted on a frame, and, together with the frame on it, and an adjacent rack). Mounted on a fenced object device with their racks 1 is installed in the ground. Rigidly fixed to the frame 5, with a knitting wire 4 and brackets 8, the web 2 is installed together with the frame on the racks, for example, they are welded using strips 9 - by welded joints (the strips are welded with frames and racks).

In this state, the device is used for its intended purpose, exploiting in its work its potential ability to weave the strands of tape of the barbed reinforced safety barriers, their shape, as well as the ends of the barbed cloth protruding above the frame, to serve as an obstacle to overcome it.
