Definitions

• the invention relates to a protective net, in particular for stone chip protection or for securing embankments, according to the preamble of claim 1.
• a protective network of this type is disclosed in EP-B-0 979 329.
• the protective net is designed as a diagonal braid with rhomboid-shaped meshes and a three-dimensional mattress-like structure, which is braided from individual helically bent wires made of high-strength steel.
• the wires have a high tensile strength, so that the braid retains a three-dimensional mattress-shaped structure even when stretched and can serve as a support or stabilizer for vegetation layers when covering an earth surface.
• the wire mesh can be folded up and takes up little space for storage or transport. Thanks to the high flexural strength of the wires, the risk of a running stitch is reduced in the event of a broken wire.
• the present invention has for its object to further improve a protective network of the type mentioned and to significantly reduce the risk of breakage.
• the protective net according to the invention is braided from individual helically bent wire strands, wire ropes or wire bundles, which advantageously comprise two or more wires (or wire strands) made of high-strength steel, a protective net with high strength is created which practically does not allow any deformation under loads and does without mesh fixing elements (e.g. cross clamps).
• the diagonal braid according to the invention made of wire strands, wire ropes or wire bundles can be produced practically “endlessly” in rolls, with high-strength edge knots also advantageously being provided on the long sides of the rolls Form of loops formed on wire strand, wire rope or wire bundle ends are provided.
• FIG. 1 is a plan view of a mesh of a protective network according to the invention
• Fig. 3 is a partial side view of the protective network of FIG. 1, and
• Fig. 4 is a schematic view of a protective network system as slope protection on a slope.
• Fig. 1 and Fig. 2 each show a protective net for securing a layer of earth surface, such as a slope protection or a rock wall protection on a road or the like, which is designed as a, for example, square diagonal braid 10 with four or polygonal meshes 17.
• the diagonal braid 10 is braided from a number of helically bent wire strands, wire ropes or wire bundles 11, 12, 13, 14, each of which comprises two or more wires 22 made of a high-strength steel. These can be two or more wires twisted into a wire strand, two or more wires bundled into a wire bundle, wire strands twisted into a wire rope, or a combination of these elements.
• the wires have a nominal strength between 1000 and 2200 N / mm, for example one of 1770 N / mm.
• spring steel wires according to DIN standard 17223 could also be used. be used.
• the wire thickness depends on the required tensile strength and can be, for example, 3 mm.
• These wires 22 are usually galvanized, provided with a coating of zinc / aluminum and / or a plastic coating or made of a chromium alloy in order to achieve the required corrosion resistance.
• a galvanized coating with a basis weight between 100 and 250 g / m is provided.
• the wire strands or wire ropes or wire bundles 11, 12, 13, 14 are articulated to one another in pairs by loops 11 ", 12", these loops 11 ", 12” being connected by the wire strands bent at the ends or Wire ropes or wire bundles 11, 12, 13, 14 themselves are formed.
• the wire strands or wire ropes or wire bundles 11, 12, 13, 14, after they have been bent into loops, are additionally provided with a plurality of loops 19 which are wound around their own circumference and which, owing to the tensile load on these loops in the inserted state, are sufficient Ensure security against opening.
• the diagonal braid 10 is held on the ground in a defined tension by fastening elements 15 recessed in the ground.
• a wire or a rope 21 is looped into each of the helical bent edge wire rope or edge wire strand or edge wire bundle 11 located at the upper and lower ends of the braid 10, which wire is in turn tensioned by the fastening elements 15 on the floor or the like.
• the fastening elements 15 could also hold the loops 11 'directly.
• the individual helically bent wire strands, wire ropes or wire bundles 11, 12, 13, 14 have a pitch angle ⁇ and a length L between two bends, which determine the shape and size of the meshes 17 of the diagonal braid 10.
• the individual meshes 17 each form a rhomboid, the mesh size being, for example, 77 ⁇ 143 mm. This has the advantage that the braid 10 does not stretch significantly if it is laid out on a layer of earth's surface and is pretensioned by the cables 21 in its longitudinal extension. In addition, the individual meshes 17 thereby form a rhomboid with an elongated opening, which gives the advantage of a lower permeability of earth material.
• the individual wire strands, wire ropes or wire bundles 11, 12, 13, 14 are articulated to one another in the braided state, with the result that the diagonal braid 10 can be folded or rolled up like a mat. As a result, a small amount of space is required for the storage and transportation of such braids.
• the braid 10 has a three-dimensional, mattress-like structure, which in turn is made possible by the use of the high-strength steel wires.
• the individual wire strands, wire ropes or wire bundles 11, 12, 13, 14 are bent in a helical shape and then intertwined with one another in such a way that the cross-section of the resulting braid 10 forms an approximately rectangular outline.
• the wire strands, wire ropes or wire bundles therefore consist of curved parts 11 'and straight parts 91.
• This elongated rectangle has a thickness 10' of several wire rope or wire strands. Thick. This wire mesh 10 is therefore three-dimensional even in the prestressed state.
• this three-dimensional design additionally provides support or stabilization of the vegetation layers introduced into this network or of sprayed-on covers when covering a ground surface, for example an embankment.
• the protective net is braided according to the invention from individual helically bent wire strands, wire ropes or wire bundles which have two or more wires made of high-strength steel twisted together or combined to form a wire bundle or of two or more wire strands made of " high-strength steel " twisted to form a wire rope are formed, a high-strength protective net is created, which practically does not allow any deformation under loads and does not require mesh fixing elements (e.g. cross clamps).
• mesh fixing elements e.g. cross clamps

• the protective nets can also be made of wire strands, wire bundles, spiral ropes with thinner or thicker wires, which are not or only partially made of high-strength steel.
• 4 shows a system of a protective network 10 according to the invention, which in the present case is provided as slope protection 40, for example an slope 45 located on a steep slope, which forms the layer of earth surface to be secured.
• This slope protection 40 consists of the wire mesh 10 laid out over a desired slope area and of the fastening elements 15 sunk into the ground with claw plates or the like pressing the mesh 10 onto the earth's surface.
• Known ground or rock nails are used for the fastening elements 15, which are preferably fastened at regular intervals in the embankment 45.

• High-strength wires are advantageously used at least partially in the strands, wire bundles or wire ropes. However, wires with lower strength could also be used for this. Due to the fact that thicker wire bundles can be used compared to individual wires, the overall strength can be increased in this way.
