Description

Die Erfindung betrifft ein Drahtseilnetz für Steinschlag-, Holzschlag- oder Lawinenverbauungen sowie ein Verfahren zur Herstellung desselben.The invention relates to a wire rope network for rockfall, logging or avalanche barriers and a method for producing the same.

Solche Drahtseilnetze, auch Auffangnetze genannt, werden üblicherweise zwischen im Boden verankerten, aufrecht stehenden Trägern angeordnet und über Drahtseile mit den Trägern verbunden. Dabei können diese Drahtseile mit Federgliedern ausgerüstet oder durch Seilbremsen hindurch geführt sein, um einen Teil der Energie des auf das Netz aufprallenden Gutes aufzunehmen. Weiter sind Drahtseilnetze bekannt, die aus Ringen aufgebaut sind.Such wire rope nets, also called safety nets, are usually arranged between upright beams anchored in the ground and connected to the beams via wire cables. These wire ropes can be equipped with spring links or can be guided through rope brakes in order to absorb part of the energy of the material hitting the net. Furthermore, wire rope nets are known which are made up of rings.

Die bekannten Drahtseilnetze weisen ein beträchtliches Gewicht auf und bedingen einen beträchtlichen Aufwand zur Fertigung.The known wire rope nets have a considerable weight and involve a considerable amount of production.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, ein Drahtseilnetz für Steinschlag-, Holzschlag- und Lawinenverbauungen sowie ein Verfahren zur Herstellung derselben zu schaffen, welches eine Ersparnis an der Menge der dazu notwendigen Drahtseile erlaubt und mit wenig Aufwand herstellbar ist.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of creating a wire rope network for rockfall, logging and avalanche barriers and a method for producing the same, which allows a saving in the amount of the necessary wire ropes and can be produced with little effort is.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass im Vergleich mit einem aus Ringen aufgebauten Netz derselben Maschenweite zur Herstellung eines gemäss der Erfindung aufgebauten Drahtseilnetzes ungefähr 20 % weniger Seil benötigt wird, was zu erheblich kleineren Kosten für das Material führt. Weiter kann die Fertigung viel einfacher sein.The advantages achieved by the invention are essentially to be seen in the fact that compared to a network of the same mesh size made up of rings, approximately 20% less rope is required to produce a wire rope network constructed according to the invention, which leads to considerably lower costs for the material. Manufacturing can also be much easier.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert.

  • Abbildung 1 zeigt einen Teil eines Drahtseilnetzes,
  • Abbildung 2 zeigt zwei wellenförmig verformte Drahtseile zur Illustration des Herstellungsverfahrens, und
  • Abbildung 3 zeigt ein wellenförmig verformtes Drahtseil zur Illustration der geometrischen Form der Maschen.
The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment.
  • Figure 1 shows part of a wire rope network,
  • Figure 2 shows two wavy wire ropes to illustrate the manufacturing process, and
  • Figure 3 shows a wavy wire rope to illustrate the geometric shape of the mesh.

Abbildung 1 zeigt einen Ausschnitt aus einem Drahtseilnetz, das aus mehreren miteinander in Form von Maschen verbundenen Drahtseilen 1,2,3,... zusammengesetzt ist. Bei ihren Enden sind die Drahtseile 1,2,3,... durch herkömmliche Verbindungsteile, Schlaufen, Klemmen, etc. die mit den Bezugsziffern 4 und 5 angedeutet sind, miteinander verbunden. Die an sich bekannten Drahtseile zur Verbindung des Drahtnetzes mit Stützen können, wie aus der Abbildung 1 deutlich ersichtlich ist, durch die Schlaufen 6,7,8,9 des obersten Drahtseiles 1, durch die Schlaufen des untersten (nicht sichtbaren) Drahtseiles des vollständigen Netzes, und durch die äussersten Schlaufen 6,10,11 links und rechts (nicht sichtbar) geführt werden.Figure 1 shows a section of a wire rope net, which is composed of several wire ropes 1, 2, 3, ... connected together in the form of meshes. At their ends, the wire ropes 1, 2, 3, ... are connected to one another by conventional connecting parts, loops, clamps, etc., which are indicated by the reference numbers 4 and 5. The wire ropes known per se for connecting the wire mesh with supports can, as can be clearly seen in FIG. 1, through the loops 6, 7, 8, 9 of the uppermost wire rope 1, through the loops of the lowest (not visible) wire rope of the complete mesh , and through the outermost loops 6, 10, 11 on the left and right (not visible).

Die Drahtseile 1,2,3 können unterschiedlich gewellt sein, d.h. die einzelnen Maschen können unterschiedliche Formen aufweisen. Die bevorzugte Form ist in Abbildung 3 dargestellt. Es ist ersichtlich, dass die Form der Maschen von einer Kreisform abgeleitet ist. Das Drahtseil 1 ist ausgezogen gezeichnet und der ergänzende, geometrische Kreisbogenteil ist punktiert angedeutet und mit der Bezugsziffer 12 bezeichnet. Es ist ersichtlich, dass der Kopf 13 jeder Masche 14 einen Kreisbogen mit einem Zentrierwinkel von mehr als 180° beschreibt. Weiter ist ersichtlich, dass die Maschen grundsätzlich nur einen Maschenkopf, jedoch keine Maschenschenkel aufweisen. Benachbarte Maschen 14 schliessen somit mit ihren Köpfen 13 unmittelbar aneinander an, wobei die Köpfe 13 jeweils in entgegengesetzten Richtungen weisen.The wire ropes 1, 2, 3 can be corrugated differently, ie the individual meshes can have different shapes. The preferred form is shown in Figure 3. It can be seen that the shape of the mesh is derived from a circular shape. The wire rope 1 is drawn in solid lines and the supplementary, geometric circular arc part is indicated by dotted lines and is designated by the reference number 12. It can be seen that the head 13 of each stitch 14 describes an arc with a centering angle of more than 180 °. It can also be seen that the stitches basically have only one stitch head, but no stitch legs. Neighbors Stitches 14 thus directly adjoin one another with their heads 13, the heads 13 each pointing in opposite directions.

Die Herstellung des Drahtseilnetzes ist denkbar einfach und wird nun insbesondere unter Bezugnahme auf die Abbildung 2 erläutert.The manufacture of the wire rope network is very simple and will now be explained in particular with reference to Figure 2.

Ein erstes Drahtseil 2 wird mittels einer Formvorrichtung zur in der Abbildung 2 gezeigten Wellenform umgeformt, derart, dass die gezeichneten Köpfe 10,16, 17,18,... entstehen. Danach wird ein zweites Drahtseil 1 in derselben Weise geformt, so dass die Köpfe 6,7,8,9,... gebildet werden. Danach wird das Drahtseil 1 gegen das Drahtseil 2 geschoben und alle Köpfe 6,7,8,9,... relativ zur Zeichnungsebene der Abbildung 2 von oben her durch die Köpfe 10,16,17,18,... hindurchgesteckt, so dass die in Abbildung 1 gezeichnete Anordnung der zwei Drahtseile 1,2 erreicht wird. Ein nachfolgendes Drahtseil wird dann mit den Köpfen durch die Köpfe 6,7,8,9,... hindurchgesteckt, und diese Vorgänge werden mit weiteren Drahtseilen wiederholt, bis das vollständige Drahtseilnetz gebildet ist.A first wire rope 2 is shaped by means of a shaping device to form the waveform shown in FIG. 2 in such a way that the drawn heads 10, 16, 17, 18,... Are formed. Then a second wire rope 1 is formed in the same way so that the heads 6, 7, 8, 9, ... are formed. Then the wire rope 1 is pushed against the wire rope 2 and all heads 6, 7, 8, 9, ... are inserted through the heads 10, 16, 17, 18, ... from above relative to the plane of the drawing in Figure 2, see above that the arrangement of the two wire cables 1, 2 drawn in Figure 1 is achieved. A subsequent wire rope is then inserted with the heads through the heads 6, 7, 8, 9, ..., and these processes are repeated with further wire ropes until the complete wire rope network is formed.
