Description

The utility model relates to the field of construction and can be used to block protected objects, in particular military, warehouses, industrial enterprises, etc.

A lattice fence of rolled metal is known, containing a frame and a lattice fastened to it, which includes a combination of curved cells formed by cross-laying at the transition points between cells of the same rod and located at a certain step relative to the frame, characterized in that the cells are formed by plastic bending a bar of mild steel with a simple profile and the cell spacing in the grid is equal to or greater than the characteristic size of the closed cell, while the final dimensions of the grid are obtained by stretching it then closed cells in the lattice are located on different sides from the axis of symmetry of the lattice by 180 ° plastic twisting of the rolled bar at the points of transition between the closed cells, closed cells in the lattice are oppositely to each other, the step of changing the direction of the plastic bending of the rolled bar and the plastic twisting step the rolled bar is a multiple of one or more closed lattice cells, the lattice is formed by the superposition of two rolled bars with their cross superposition in places of plastic twisting, (analog ). (see. Lattice fencing from rolled metal and the method of its production, description to the patent of the Russian Federation No. 2107792, IPC Е04Н 17/04 dated 12.27.95., publ. 1996.03.27., auth. Khloponin V.N., Romantsev B.A. ., Galkin S.P., Kishkin I.V.).

Disadvantages: there are no piercing and cutting elements of the wire, both in the frame itself and around the perimeter.

The closest in combination of essential features and technical result achieved is the fencing description to copyright certificate No. 5686266, IPC E04H 17/04 dated 10.11.75., Publ. in bull. No. 48 12.30.77., Ed. Belokone A.A., Zinkovsky B.D. (prototype) which

made of interconnected blocks having racks, connecting rigid elements and barbed wire strands, where the blocks are made folding in the form of paired sections having a common rack located in the middle of the block, while the rigid connecting element of one of the sections is made in the form of a cross member uniting block racks, and the rigid element of the other section is in the form of a bar combining strands of barbed wire attached to the middle rack, while the latter is attached to a common rack with the possibility of rotation around it.

Disadvantages: there are no stitching, cutting elements of the wire along the upper and lower borders of the fences, which facilitates their overcoming, both from above and underneath from below.

Technical result: increasing the insufficiency of the fence for not authorizing access to the territory of the object, due to its high piercing and cutting properties, reducing metal consumption, which is achieved due to the fact that in the known device the blocks are made in the form of a volume spiral made of reinforced barbed tape (AKL), in which the planes of the barbed tape are located to each other at an obtuse angle relative to the reinforcing wire and the adjacent spiral coils are staggered to each other with brackets from a strip of steel, with the ends along wasps overlap over the other end of the strip, and the number of rows of staples equidistant along the arc of the spiral circle can be from a series of odd numbers, for example at least 3, and the upper and lower parts of the spiral turns have cutting and piercing elements of reinforced barbed tape with cutting planes at an obtuse angle this creates the greatest insuperability of the fence, both from above and from below due to prickly-cutting properties. They do not allow objects to slide along the plane of the barbed tape and increase the exciting and wounding effect of the AKL spiral. The spiral made of reinforcing spring steel wire does not sag due to the stapling of adjacent turns in a checkerboard pattern. This implementation gives minimal use.

reinforced barbed tape with a maximum coverage of the block area, i.e. reduced metal consumption of the structure. Barbed tape is saved with this design of the fence.

Statics.

Volumetric fencing made of AKL is made in the form of blocks of a volumetric spiral 1 of reinforced barbed tape 2, in which the planes of barbed tape 3 of Figure 3 are located to each other at an obtuse angle "A" of Figure 3, relative to the reinforcing wire 10 of Figure 3. and adjacent coils 4 of FIG. 1 are staggered to each other by brackets 5 from a steel strip 6 of FIG. 4, the ends of the strip 7 overlapping the other end of the strip 8 of FIG. 4, and the number of rows of brackets 5 of FIG. 2 equidistant along the arc of the circle of the spiral 9 can be from a row odd numbers, for example at least 3.

An example of the operation of the device.

In Fig. 1, the enclosure made of AKL is made in the form of volumetric spiral blocks 1 made of reinforced barbed tape 2 (in transport mode), in which the planes of the barbed tape 3 are located at an obtuse angle "A" to each other, Fig. 3 relative to the reinforcing wire 10 .3, and adjacent turns of the spiral 4 of Figure 1 are connected in a checkerboard pattern to each other with brackets 5 from the steel strip 6 of Figure 4, the ends of the strip 7 overlapping the other end of the strip 8 of Figure 4, and the number of rows of brackets 5 of Figure 2 spiral 9 equally spaced along the arc of a circle may be from a series of odd numbers, for example not less than 3.

The upper and lower parts of the coils of the spiral have prickly cutting elements and do not allow to overcome the spiral both from below and from above. The fence is installed both directly on the ground and not on the fence, and when installed, the spiral from the transport view is pulled into the working position (not shown in Fig.).

The implementation of a bulk enclosure made of AKL in the form of a three-dimensional spiral can significantly reduce the consumption of barbed wire, which makes the fence less metal-intensive, due to its high stitching and cutting properties, insurmountability increases.

Prototypes of bulk enclosures made of AKL were made.

The height of the fence (spiral diameter): 0.5 meters; 0.6 meters; 0.9 meters; 1.2 meters. The length of the fence is from 6 to 50 meters (in the extended position) in one transport bay.

The spiral was made of AKL (reinforced barbed tape) at the rate of 56 turns per 20 linear meters. The number of staples in the rows is 3 rows for a spiral diameter of 500 mm, and 5 rows for a diameter of over 600 mm, 7 rows for a diameter of over 900 mm. The diameter of the reinforcing spring wire is 2.4 mm or 2.5 mm. Barbed tape is made of steel strip 0.55 mm thick. The staples are made of galvanized steel with a thickness of 1.2 mm. Staple width 10 mm.

AKL cannot be eaten with ordinary locksmiths.

Technical and economic indicators.

The greatest effectiveness of the insuperability of the fence compared with the prototype is multiple. The cost of the product is lower by an order of magnitude.
