Description

Technology area

The utility model relates to wire nets used for fencing nurseries, nature reserves, wildlife preserves, forestry areas, hunting grounds, agricultural areas, animal enclosures.

Prior art

Wire mesh is widely used in fencing. In particular, the known wire mesh with a fixed knot, widely represented on the Internet and disclosed in the patent of the Russian Federation No. 108706 from 27.09.2011.

At the same time, the use of corrugated mesh is known, see, for example, https://ru.wikipedia.org/wiki/Refleted_Grid, including in barriers, for example, https://protect-market.ru/blog/riflenaya- setka-dlya-zabora. Corrugated mesh is made from curved steel wire. Due to the presence of bends, which serve as stiffeners, the mesh receives additional strength.

The closest analogue of the claimed wire mesh is the wire mesh disclosed in RF patent No. 133862 dated October 27, 2013, used in barriers and consisting of longitudinal wires located along the fence and transverse wire sections fastened with wire clamps at the intersection with longitudinal wires, each clamp dressed on a transverse wire located at the intersection above the longitudinal wire, the ends of the clamp are separately, on opposite sides from the transverse wire, wound onto the longitudinal wire and coiled onto the transverse wire from the opposite side of the longitudinal wire in relation to the place where the clamp is worn on the transverse wire.

However, this known wire mesh has insufficient resistance to animal impacts, which has to be compensated for by increasing the diameter of the wire used, increasing the weight and weight of the wire mesh and the fence.

It should be noted that wire meshes with a curved transverse wire at the intersection with the longitudinal mesh are known, but these bends are not regulated in the production of the mesh and are of a random nature.

The claimed utility model is aimed at increasing the strength and resistance of the wire mesh to shock loads.

Disclosure of a utility model

The technical result achieved in the claimed wire mesh is to increase the resistance of the wire mesh to shock loads due to the bends of the transverse wires at the intersection with the longitudinal wires.

The specified technical result is achieved in a wire mesh used in fences and consisting of longitudinal wires located along the fence and transverse wire segments located at the intersection above the longitudinal wire and fastened with wire clamps at the intersection with longitudinal wires, each clamp is dressed on a transverse wire , the ends of the clamp are separately, on opposite sides from the transverse wire, wound onto the longitudinal wire and together are wound onto the transverse wire from the opposite side of the longitudinal wire in relation to the place where the clamp is put on the transverse wire, while the transverse wires are made with a bend at the intersections with longitudinal wires, and the points of contact of the clamp with the transverse wire are spaced from the intersection of the longitudinal and transverse wires (respectively, and from the longitudinal wire) at a greater distance than the points of contact of the clamp with the longitudinal wire are spaced from the transverse wire (respectively, and from the intersection of the longitudinal and transverse wires).

Implementation of the utility model

In the wire mesh shown in FIG. 1, at the intersection points 1, transverse wires 2 located vertically in the barrier and longitudinal wires 3 located horizontally along the barrier are connected to each other by wire clamps 4, see also FIG. 2. Each clamp 4 is put on a transverse wire 2, located at the intersection above the longitudinal wire 3, the ends 5 and 6 of the clamp, separately, on opposite sides of the transverse wire 2, are wound onto the longitudinal wire 3 and then coiled onto the transverse wire 2 from the opposite sides of the longitudinal wire 3 in relation to the place where the clamp 4 is put on the cross wire 2.

Clamp 4 contacts the transverse wire 2 on opposite sides of the longitudinal wire 3, in the place where the clamp 4 is put on the transverse wire 2, and in the place where the ends 5 and 6 of the clamp 4 are co-wound onto the transverse wire 2. The clamp 4 contacts the longitudinal wire 3 (as indicated above) also on opposite sides of the cross wire 2.

When installing the clamp, first, when winding the ends 5 and 6 of the clamp 4 onto the transverse wire 2, the clamp 4 presses on the transverse wire in the place where it is dressed, creating a moment of force relative to the intersection of the longitudinal and transverse wires and bending the transverse wire. Then, with the joint winding of the ends 5 and 6 of the clamp 4, another moment of force is created relative to the intersection of the longitudinal and transverse wires. Both moments of force provide plastic deformation of the transverse wire as it bends at the intersection with the longitudinal wire, as shown in FIG. 3. In this case, two moments of force act on the longitudinal wire relative to the intersection of the longitudinal and transverse wires. To prevent bending of the longitudinal wire, the moments of force acting on it are reduced in comparison with the moments of force acting on the transverse wire, due to the reduction of the arms - the distances from the transverse wire to the places where the ends 5 and 6 of the clamp 4 are wound onto the longitudinal wire in comparison with the arms of the moments of forces bending the cross wire.

The bends of the transverse wires at the points of intersection with the longitudinal wires serve as stiffeners that strengthen the wire mesh. The greatest increase in the resistance of the wire mesh to shock loads occurs when the distance between the bends of the transverse wires decreases. In wire nets intended, for example, for animal enclosures, the smallest distance between the bends of the transverse wires is realized at the bottom of the fence. Thus, the greatest resistance is ensured against impacts, in particular, by the hooves of animals.

It is also essential to be able to roll wire nets made in accordance with the claimed utility model and intended for use in long fences, since only transverse wires are bent at the intersection of the wires.
