Fences: Where is it installed?

Barbed wire fences can often be seen on top of fences around summer cottages, a country house, or even a city house. But it is still actively used for fences around pastures, corrals. 

And also the barbed wire is mounted:

  • around prisons;
  • at military facilities;
  • at train stations and stations;
  • at airports;
  • at service aerodromes;
  • in warehouses;
  • at retail facilities;
  • at industrial enterprises;
  • in ports.

Installation rules

Fastening of vertical supports dug into the ground, is carried out in increments of no more than 3 m. These supports are quite enough for mounting the wire itself, nothing else is required. But an increase in the degree of security is possible only with additional tension of the wire in the transverse plane with respect to the main strip. The barbed thread can be used in addition to the already created protective structures. In this case, it is mounted on top of fences and gates.

Reinforced tape is much more difficult to assemble. To install it you will need:

  • scissors for cutting metal reinforcement;
  • Grinder;
  • some other tools, depending on how the wire is attached to the anchor points.

Wire installation will be simplified by using special brackets. For flat and spiral models, the same type of brackets can be used. It is permissible to mount them in a variety of places. Now they sell crumbs of different formats:

  • direct;
  • L-shaped;
  • Y-shaped.

The fence should be prepared independently with a step between the brackets of no more than 2.5-3 m. You need to work not only in protective gloves but also in tight clothing. Sometimes it makes sense to even wear safety glasses. The shape of the bracket is selected taking into account the ease of installation. Before starting work, the area should be marked out.

Anchor points are fixed using bolts or by welding. Then a spiral is mounted on top of the crumbs using special brackets. The next step is to pull the double string along the entire length of the spiral. The spiral itself is aligned, and it is fixed using twists of a special pattern.

Finally, the individual parts of the wire fence are connected using mounting brackets. If the fence will be energized, you must warn about this by hanging special signs around the perimeter with a clear warning text.

Main types

Galvanized

For all the external similarities, modern barbed wire is not exactly the one that was patented at the end of the 19th century. By now, about 450 patents have been issued for it. Collectors of wire fences (there are, it turns out, such) number up to 2 thousand different types and samples. In the catalogs of manufacturers, only 2 dozen main varieties are often mentioned. The simplest option is a single-core corrugated construction with spikes throughout.

The thickness of such a product is most often 2.8 mm. It is this option that is usually used in summer cottages and fences around private houses.

Reinforced

Coating with a protective zinc layer does not always help to solve the assigned tasks. Sometimes a more significant strengthening of the enclosing structure is required.

A typical barbed wire texture looks like this.

Products operating under-voltage must be rated for a current of 2-10 kV. They are mainly produced for livestock and penitentiary purposes. Returning to tape structures, it is worth pointing out that they can damage significant areas of soft tissue. They are used to protect structures, including those mounted on frames and supports.

However, over time, such a fence weakens and begins to sag intensively. This disadvantage is especially pronounced with a significant length of spans. The problem is not too significant if you mount the wire in small areas. In addition, technologists distinguish piercing-cutting tape and reinforced “twist” in a special category. All the rest, experts consider them to be the only subspecies of the three main types of barbed wire.
