Abstract

Closure element for connecting / connecting together meshes of wire mesh or wire nets, which closure element consists of a high-strength elastically deformable wire and in the use state as a basic structure has a substantially closed ring shape, characterized in that the wire in the original state of the closure element to a closed, annular Basic structure is bent, such that the ends of the bent to the annular base structure wire are touching each other, and that adjoin the two wire ends of the closed, annular basic structure wire sections (1.2), which extend crossing each relative to each other diverging.

Description

The invention relates to a closure element according to the preamble of claim 1.

Mesh nets and wire netting (wire mesh) are used to secure unstable slopes in rock and unconsolidated rock. To connect or to each other connecting individual network panels and / or tracks these net panels or tracks are sewn along the joint with wire ropes, looped or fixed with ferrules. For the transmission of power between the net panels and attached to the edge suspension ropes defined requirements for the tensile strength of these fasteners arise. Established has a value of about 5 kN. Known connection means or pressing clamps require the use of tools or a two-handed operation, e.g. when screwing the shackles, or require a lot of effort.

In the CH 699 050 B1 For example, a press claw for connecting meshes of wire mesh or wire nets and a device for closing the press jaw are described. This press claw consists of a corrosion-protected wire and has two of a rounded base projecting away from each other an opening angle enclosing legs, which are provided at their free end with a hook, the two hooks are directed against each other. The legs lie in two angles enclosing an angle, so that the two hooks are movable past each other when closing the press jaw. The press claw is opened in the original state, so that it can be hooked in a simple manner between adjacent, interconnected meshes of wire mesh or wire nets. After this hooking the two hooks of the presser jaw must be pressed together with great force and hooked together.

To meet the mechanical requirements of connecting mesh braids of wire mesh or wire nets, the press jaw consists of a high strength steel wire having a wire diameter of e.g. 3 mm. Even the term "press claw" used expresses the fact that this known connection element must be compressed, for which purpose a suitable device is described in this document. In conclusion, it should be noted to this known press jaw that it can be attached using two hands only with great effort, or by means of a corresponding tool to be joined together wire mesh or wire nets.

Comparable conditions are at a in the US 4,476,616 described claw or clip for connecting in particular wire-like structures before. This claw or staple has the form of an open ring in the original state, which consists of high-strength spring steel wire to withstand higher loads. At the ends of the open ring, two opposing hooks follow, which must be hooked together in the use state for connecting two wire elements or the like, for which purpose a suitable device is described in this document.

The invention has for its object to provide a closure element for connecting or connecting to each other of meshes of wire mesh or wire nets, which can also be brought without a tool and without much effort, preferably one-handed in the closed position.

To achieve this object, a closure element according to the invention with the features of the characterizing part of claim 1 is used

To tighten the closure element this is placed in the region of the diverging legs on the wire of the wire mesh or wire mesh, so that this wire then without much effort and one-handed sliding along this leg and the contact point between the two legs can be introduced into the annular base structure ,

After placing or attaching the connecting element to be connected to each other power supply or supporting cables sufficient rotation of the connecting element by hand, whereby the gap between the abutting wire sections opens, so that the connecting element substantially to the power supplies and / or ropes is screwed on. Subsequently, the gap closes again, and the stitches and / or supporting cables to be connected are located inside the basic structure.

• – bessere Handhabung bei der Montage durch einen vergrößerten Drehhebel;
• – lastoptimierte Formgebung;
• – ein seitlicher Versatz von Netzpaneelen kann durch die längliche Form besser ausgeglichen werden;
• – Einsatz unterschiedlichster Seil-/Drahtdurchmesser möglich;
• – Möglichkeit der Netzbefestigung an Tragseilen mit größeren Durchmessern bei kompakter Bauform.

According to a preferred embodiment of the invention, the wire is bent into an ellipsoidal basic structure, resulting in the following advantages:

• - Better handling during assembly by an enlarged rotary lever;
• - load-optimized shaping;
• - a lateral offset of net panels can be better compensated by the elongated shape;
• - Use of different rope / wire diameter possible;
• - Possibility of net attachment to support cables with larger diameters in a compact design.

The measures provided for in claim 3 hooks that get caught in a possible pulling apart of the annular base structure in the use state improve or increase the functionality of the connecting element.

As usual, the closure element consists of spring steel wire, which preferably has a tensile strength of> 1350 kN / mm ² . Usual wire diameters are between 2.5 and 5.0 mm. Variants may consist of fiber composite material or high-strength plastics, with diameter dimensions of about 60 mm are common.

• – sehr hohe Festigkeiten bei geringem Gewicht;
• – Resistenz gegenüber korrosiven Medien und keine Kontaktkorrosion;
• – erhöhte Zugfestigkeiten gegenüber Stahl;
• – lastoptimierte (freie) Formgebung;
• – nicht magnetisch und elektrisch isolierend.

Made of fiber composites and / or thermoplastics / thermosets fasteners are characterized by a variety of advantages, in particular

• - very high strength with low weight;
• - Resistance to corrosive media and no contact corrosion;
• - increased tensile strength compared to steel;
• - load-optimized (free) shaping;
• - non-magnetic and electrically insulating.

The invention will be described below with reference to the drawing:

1 shows in a schematic way two interconnected by means of the connecting element according to the invention network structures;

2 shows a side view of the connecting element;

3 shows an end view of the connecting element;

4 shows a plan view.

1 shows a schematic representation of two adjacent network structures A and B, by means of the closure elements according to the invention 1 are positively connected with each other.

According to 2 the wire used or spring steel wire is bent in the side view to a closed, annular, preferably ellipsoidal shape, ie it is an ellipsoidal basic structure 1.1 in front.

At the mutually contacting ends of the annular, preferably ellipsoidal basic structure 1.1 forming wire preferably close substantially rectilinear wire sections 1.2 which is different from the basic structure 1.1 extend to the outside and are crossing each other in a divergent relative to each other. The two thighs 1.2 lie against each other in the area of the crossing point.

At the ends of the legs close in the direction of the basic structure 1.1 arched bent hooks 1.3 at, the free legs converge to each other.
