Abstract

The invention concerns a protective mesh, in particular for securing slopes, which is laid on an earth surface (12) and secured thereon by a number of mutually spaced-apart securing means (20). These securing means comprise longitudinal elements (15) anchored in the ground and spike plates (25) which can be laid on the protective mesh (10). These spike plates (25) are dimensioned and designed such that the number of securing means (20) per unit of area can be reduced and the rigidity of the laid-on protective mesh (10) increased.

Protective mesh, in particular for securing slopes, and . associated spike plate Py D »
The invention relates to a protective mesh, in particular for securing siopes = and to an associated spike plate according to the preamble to Claims 1 and 2. eo i
Such protective meshes are fixed to earth surfaces which are at risk due to o instabilities, such as erosion, falling stones or rocks or parts of the ground that oO become detached. One thus achieves extremely environmentally friendly - securing of these surfaces. Such protective meshes have also proved to be of © particular value because with the latter, green coverage with natural growth, . such as grass, plants etc., can be achieved once again only a short time after - laying.
According to publication A-0 979 329 a wire mesh is sometimes provided for securing slopes, for example on a steep hillside. This slope securing consists of the wire mesh laid over a desired slope region and of the securing elements sunk into the ground with spike plates pushing the mesh onto the earth surface. Soil or rock nails, known in their own right, and which are preferably secured regular distances apart in the slope, are used as securing elements. The spike plate is respectively produced from a round, oval or differently shaped metal sheet with downwardly projecting, bent spikes which are respectively wedge-shaped. In the secured state a respective spike plate is pushed by the securing element onto the wire mesh and it brings about permanent securing of the slope by means of the wire mesh acting over the entire contact surface. The spikes extending through the mesh bring about wedging with the wire mesh due to their wedge shapes.
The object underlying the invention is to devise a protective mesh, in particular for securing slopes, wherein with sufficient stability of the slope to be protected simpler installation, and so a reduction in cost and increased rigidity of this type of protective mesh installation is achieved.
Cg
According to the invention this object is achieved in that the spike plates are dimensioned and designed such that it is made possible to reduce the number of securing means per unit of area and to increase the rigidity of the laid-on + protective mesh. =
Very advantageously, the spike plates are respectively provided with an - elongate outer form, preferably with a number of reinforcement ribs, at least along this elongate outer form. os +
Thus, in a decisive manner it is achievable for these spike plates to not bend = when there is an exceptional load thrust, for example if a lump of rock within = the slope covered by the protective mesh becomes detached, and so greater fd forces can be transferred from the mesh onto the longitudinal elements anchored in the ground than is possible with the known spike plates.
The invention and additional advantages of the latter are explained in more detail below by means of exemplary embodiments with reference to the drawings. These show as follows:
Fig. 1 a perspective partial view of a protective mesh according to the invention and of a fixed spike plate;
Fig. 2 a version of a spike plate according to the invention;
Fig. 3 another version of a spike plate; and
Fig. 4 a diagrammatic view of slope securing with a number of securing means.
Fig. 1 shows a partially illustrated protective mesh 10 which is laid over an earth surface 12 in order to secure the slope and is pressed on by securing means 20. These securing means 20 consist of spike plates 25 and longitudinal elements 15 secured in the ground, these longitudinal elements being made in the form of screws, at least at the end projecting from the ground, and being used as so-called soil or rock nails. The spike plate 25 can be pressed onto the mesh by means of a nut 16.
This protective mesh 10 is made in the form of a wire mesh with rhomboidal meshes 11 and it consists of individual, helically bent wires 13, 14 which are twisted together. The individual wires are preferably produced from high- strength steel with nominal strengths of 1,000 to approx. 2,700 N/mmZ.
Needless to say, wire strands or similar could also respectively be used instead of wires 13, 14.
According to the invention the spike plates 25 are dimensioned and designed such that it is made possible to reduce the number of securing means 20 per unit of area and to increase the rigidity of the laid-on protective mesh 10.
For this purpose the spike plates 25 are respectively provided with an elongate outer form with a reinforcement rib 26, 27 on each of the two sides and a cross bar 28 connecting the latter. At the two ends of the narrow sides these reinforcement ribs 26, 27 are arranged so as to converge and form a blunt point and are each formed on the outside with a downwardly bent spike (not detailed). The spike plates 25 each cover a specific number of meshes 11 of the wire mesh, and they engage in these meshes with their bent spikes.
The outer form of the plate is respectively also in the form of a rhomboid, these being able to be provided in different forms.
An opening for receiving the longitudinal element 15 projecting over the ground is provided in the cross bar 28 in the centre of the spike plate 25. In addition, a cavity 29 is allocated between the reinforcement ribs 26, 27, through which cavity the vegetation can also grow, and so over time these spike plates also become invisible.
Furthermore, another textile mesh 17 with smaller meshes than in the protective mesh 10 is disposed between the latter and the ground. By means of this textile mesh it is ensured that smaller stones or pieces of earth can not fall down.
.
The spike plate 21 according to Fig. 2 is designed similarly to that according to Fig. 1. Once again it has an elongate outer form and at the two narrow = ends 22 converges to form a blunt point. On the outside it is provided ~ respectively with a bent spike 23, and the reinforcement ribs 24 are made in ow the form of elongate reshaped grooves in the plate 21 in the form of a sheet. »
On either side of the central opening 19 additional bent over spikes 23’ are = formed. = ;
In the spike plate 31 according to Fig. 3, which is also made in the form of a co sheet, a number of star-shaped reinforcement ribs 33, 34 passing from the © central opening 32 are provided. In addition, this opening 32 is formed by a i! bent reinforcement ring 36. Therefore, according to the invention this spike = plate 31 is made with reinforcement and it fulfils the requirement of increased wo flexural strength.
Fig. 4 shows diagrammatically an installed protective mesh 10 for securing the slope on a hillside which, for example, needs to be secured against erosion. Spike plates 21 (or 31) according to the invention are held by these longitudinal elements 15 distributed in rows over the protective mesh 10. The distances 36, 37 between these securing elements 20 and spike plates can be increased by this measure according to the invention of reinforcing and enlarging the spike plates.
The invention is sufficiently displayed by the exemplary embodiments that have been explained. It could, however, be illustrated by other embodiments.
Thus, the protective mesh could also be used for other purposes in the area of mudflow or rockfall protection.
