Description

The proposed utility model relates to technical means of protection, and can be used to construct temporary boundaries for the protection of perimeters of small objects by creating a security line in the form of a quick-erected, metal, trellis fence.

The design of the quick-erected, mobile fence “M500” (MANUEL ASSEMBLY Mobile Fence) of the company “Heras”, the leading European manufacturer of mobile fences designed for perimeter fencing, is known. The fence "M500" consists of trellised sections and support-bases. Each section consists of a strong frame (diameter of vertical pipes 42 mm, horizontal 30 mm) and a grid welded to the pipes with cells 35 × 150 mm from rods with a diameter of 4 mm. Adjacent sections are interconnected by high security clamps (patent 1022969). All sections are installed in the support base, size (770 × 250 × 160) mm, made of recycled PVC. To ensure the stability of the fence, special struts are used, fixed on the fence with clamps and pins in the ground. Racks of sections (vertical tubes of the frame) are fixed on the supports-bases with special brackets installed in the holes of the supports-bases and fixed on the racks of the sections with clamps.

Signs of an analogue that match the features of the proposed utility model:

1. The presence in the composition of the mobile fencing lattice sections mounted on the supports-bases.

2. Connections of adjacent sections to each other by clamps of a high degree of security.

3. The use of mechanical equipment when assembling the fence is not required.

The significant disadvantages of this prototype device include the following:

1. The presence in the composition of the frame section of vertical and horizontal pipes reduces the blocking ability of the fence. The reduced fencing ability of the fence is due to the possibility of overcoming the fence by a climbing method using improvised means, for example, a ladder resting on the frame of the fence. The presence in the composition of the frame section significantly increases the metal consumption of the section, its mass and the complexity of manufacturing due to the welded connection of the lattice to the frame. Instead of one rack to which lattices of adjacent sections could be fixed, two vertical pipes of the frames of adjacent sections connected by clamps are used, which also increases the metal consumption of the fence.

2. The connection of adjacent sections with clamps with a special screw connection increases the assembly time of the fence and requires the use of a special tool.

3. The base supports used to install the sections, when the elevation of the terrain is different in the cross section of the perimeter route, does not provide vertical installation of the fence, which requires engineering and preparatory work for the profiling of the perimeter route and certain earthwork.

4. To ensure the stability of the fence, special struts are used. Fixing the spacers on the fence using clamps, and pins in the ground increases the assembly time of the fence.

5. To fix the struts of the sections on the support-base, a special bracket is used, which is installed in the hole of the support-base and fixed on the racks of adjacent sections with a clamp, which increases the assembly time of the fence.

The technical result obtained by the implementation of the utility model is to increase the protective properties of the fence, reduce its metal consumption, reduce the assembly time of the fence, and reduce the complexity of its manufacture and installation.

The technical result is achieved by the fact that in a prefabricated, mobile fence, consisting of racks and trellised sections, the following difference is provided - the racks of the fence consist of three parts: racks, base supports and struts pivotally connected to each other, and are made with the ability to change the angle of inclination racks in a vertical plane in the cross section of the perimeter route, and the attachment of two adjacent lattice sections of the fence is carried out to one rack by eccentric clamps, and the tops of the racks of the fence are equipped with They are equipped with a spiral safety barrier made of reinforced barbed tape.

Between the set of essential features of the claimed object and the achieved technical result there is a causal relationship, namely:

1. Adjacent lattice sections of the fence are attached to one rack. The lattice section of the fence consists of horizontally oriented straight rods fastened together and curved vertical rods having straight vertically oriented sections. The bending of the vertical rods at the top and bottom of the section provides additional stiffness to the section. To protect against climbing, a spiral safety barrier is installed at the top of the sections. Thanks to its voluminous structure, significant cutting effect and spring properties, the spiral safety barrier is a particularly insurmountable physical obstacle, which increases the barrier properties. The absence of a frame made of metal pipes reduces the metal consumption of the fence. For the manufacture of sections of the fence requires less welding, which accordingly reduces the complexity of manufacturing fencing.

2. The fastening of the lattice sections of the fence to the uprights is carried out by eccentric clamps, which reduces the assembly time of the fence and does not require the use of a special tool.

3. The rack consists of three parts: a rack, support-base and struts, pivotally connected to each other. Holes are provided in the base support to which the lower part of the spacer is attached using a pin. A set of holes in the support-base allows you to move the lower part of the strut horizontally, which allows you to change the angle of inclination of the rack and to ensure vertical installation of the fence with a difference in elevation of the terrain in the cross section of the perimeter track without engineering and preparatory work in terms of profiling the perimeter track and earthwork . The rack provides convenience of transportation and installation.

4. The spacer is pivotally connected to the stand and is attached to the support base only in its lower part using a pin, which reduces the assembly time of the fence.

5. Adjacent sections of the fence are attached to the rack using eccentric clamps, providing a rigid connection of the sections with the rack. The base support is pivotally connected to the rack and additional devices are not required to fasten the rack to the base support, which reduces the assembly time of the fence.

The utility model can significantly increase the protective properties of the fence, reduce its metal consumption, reduce assembly time, and reduce the complexity of its manufacture.

sections - (50 × 200) mm. Section width - 2450 mm. Section height - 2300 mm.

The rack consists of three parts: rack 13, support-base 3 and struts 10, pivotally connected to each other.

The support base 3 of the fence is made of steel U-shaped profile. Holes are provided in the base support to which the lower part of the spacer 10 is attached using a pin 17.

The spiral safety barrier 14 is made of reinforced barbed tape.

The device described above is mounted on the ground in the following way:

Placed on the ground, according to the marking, racks and grilles of sections 2 of the fence. Racks are deployed and installed vertically on the ground according to the marking of the perimeter route. If there is a difference in elevation of the terrain in the cross-section of the perimeter track, the lower part of the strut strut 10 is moved on the base support 3 in a horizontal plane to ensure vertical installation of the fence and fixed to the base support 3 with a pin 17. Fastening the gratings of the fence sections 2 to the racks 13 made by clamps 7. Installation of the spiral safety barrier 14 is made on top of the fence. To attach the spiral safety barrier 14 to the tops of the racks 13 of the fence, two rows of steel, galvanized wire with a diameter of 3 mm are fixed, which holds the spiral security barrier 14 in a horizontal position between the tops of the racks 13 of the fence.

The spiral safety barrier 14 is attached to the wire with an inter-turn pitch using pieces of steel, galvanized wire with a diameter of 1 mm.

The dismantling of a quick-erected, mobile fence is carried out in the reverse order.
