Safety net and producing method thereof

Abstract

In a method for the production of a safety net consisting of intermeshing rings, a wire is inserted in approximately its axial direction and shaped by bending into a ring with several windings. While being fed through, the wire is passed through two elements each provided with a through-opening and fully enclosed, and bent more or less into a ring and, with each winding, is fed through these elements, until the through-opening of these elements is more or less filled with wires. This ring withstands loads better, while at the same time being simple to produce and the wire loops are additionally more consistently held together in a ring.

Description

technical field [0001] The invention relates to a safety net and a manufacturing method thereof, in particular to a safety net used for rock avalanche or landslide defense facility engineering and a manufacturing method thereof. Background technique [0002] Safety nets made of ring-shaped parts, such as safety nets for rockfall or landslide defense works, are disclosed in EP-B-0 597 457, and are described for making safety nets like this methods and equipment. After the individual ring parts are formed by forming loose coils of a single wire or wire, some C-shaped clamps are tied around the circumference of the ring, and the coils are fastened together by the clamps, so that by the closing members way to deform it. On the periphery of the ring, at least three such clamps are arranged. When the safety net is under a tensile load situation, such as when some ore blocks fall during a rockslide, it may happen that the safety net is loaded to the limit of its extension, with ...

AI Technical Summary

Problems solved by technology

When the safety net is under a tensile load situation, such as when some ore blocks fall during a rockslide, it may happen that the safety net is loaded to the limit of its extension, with the result that the C-clamps spring open and the rings the parts can no longer be fastened together

On the other hand, due to deformation or other influences, it may also happen that the corrosion protection of these C-shaped clamps is insufficient at the interface of each clamping end.
