Description

Die Erfindung betrifft ein Auffangnetz, insbesondere für Steinschlagverbauungen, gemäss dem Oberbegriff des Anspruches 1.The invention relates to a safety net, in particular for rockfall barriers, according to the preamble of claim 1.

Ein Auffangnetz dieser Art ist beispielsweise aus der EP-A-1 205 603 bekannt. Dieses Auffangnetz weist ein aus ineinandergreifenden Ringen bestehendes Netz auf, dessen zwei Längsseiten an je einem Rand- bzw. Tragseil verschiebbar gehalten sind. Die Randseile sind an einer Anzahl von Stützkörpern befestigt, die in Abhängen, Felswänden etc. verankert sind. Zwischen dem Netz und den einzelnen Stützkörpern sind zusätzliche Verbindungselemente vorhanden, die vorzugsweise mit Bremsmitteln in Form von Bremsringen zum Absorbieren von dynamischen Energien versehen sind. Beim Hineinfallen eines Steines oder ähnlichem in das Netz werden vorerst die Ringbündel des Netzes wie bei einem Vorhang reihenweise auf den Randseilen in Richtung zu der Aufprallstelle hin verschoben und dabei ein Teil der dynamischen Energie absorbiert. Die Verbindungselemente wirken diesem Verschieben entgegen und bewirken ein Zurückhalten der Ringreihen, bis die Bremsringe gestreckt werden und in der Folge die Verbindungselemente reissen, wonach die nächsten Verbindungselemente zum Einsatz kommen, da die Ringreihen weitergezogen werden. Die gerissenen Verbindungselemente werden ausgewechselt.A safety net of this type is known, for example, from EP-A-1 205 603. This safety net has an intermeshing rings Net on, whose two long sides on a respective edge or suspension rope are held displaceable. The edge ropes are at a number of Attached support bodies that are anchored in slopes, rock walls, etc. Between the network and the individual support bodies are additional connecting elements present, preferably with braking means in the form provided by brake rings for absorbing dynamic energy are. When a stone or the like falls into the net initially the ring bundles of the net in rows like a curtain the edge ropes in the direction of the impact point shifted and thereby absorbed part of the dynamic energy. The connecting elements counteract this shift and cause a retention of the Ring rows until the brake rings are stretched and subsequently the fasteners tear, after which the next fasteners for Use come as the ring rows are moved on. The cracked Fasteners are replaced.

Ein solches Netz hat sich in der Praxis gut bewährt, da die durch den Aufprall des Steingutes entstehende Energie in hohem Masse absorbiert werden kann, ohne dass das Netz reisst und das zu stoppende Gestein durch das Netz hindurchfällt. Beim Aufprall des Steingutes ist jeweils die Ringnetzfläche zwischen den beiden der Aufprallstelle benachbarten Stützkörpern wirksam. Die Kräfte werden durch diesen Netzteil auf die beiden Stützkörper bzw. ihre Grundplatten sowie ihre in der Regel von Rückhalteseilen gehaltene Stützenköpfe übertragen.Such a network has been well proven in practice because of the impact the earthenware energy are absorbed to a high degree can, without the net breaks and the rock to be stopped by the net falls through. The impact of the earthenware is in each case the ring net surface between the two impact bodies adjacent to the impact point effective. The forces are transmitted through this power supply to the two Support body or its base plates and their usually of restraint ropes transfer held column heads.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Auffangnetz der eingangs genannten Art zu schaffen, das in seinem Aufbau und Unterhalt einfach und kostengünstig ist, und dennoch eine verbesserte Wirksamkeit zeigt. The present invention is based on the object, a safety net of the type mentioned above, in its construction and maintenance simple and inexpensive, yet improved efficacy shows.

Diese Aufgabe wird erfindungsgemäss durch ein Auffangnetz mit den Merkmalen des Anspruches 1 gelöst.This object is achieved by a safety net with the Characteristics of claim 1 solved.

Weitere bevorzugte Ausgestaltungen des erfindungsgemässen Auffangnetzes bilden den Gegenstand der abhängigen Ansprüche.Further preferred embodiments of the safety net according to the invention form the subject of the dependent claims.

Beim erfindungsgemässen Auffangnetz, bei dem die beiden Tragseile an den einzelnen Stützkörpern in ihrer Längsrichtung verschiebbar geführt und seitlich abgespannt sind und das Netz im Stützkörperbereich an an Stützkörpern vorbei verlaufenden, an den Tragseilen angebrachten Laufseilen verschiebbar gehalten ist, kann die Kräfte aufnehmende Ringnetzfläche gegenüber den herkömmlichen Auffangnetzen erheblich vergrössert werden. Das Auffangnetz gewährleistet eine optimale Lastverteilung sowie einen günstigeren Kräftefluss durch das Netz, und somit kleinere Kräfte im gesamten System. Auch die Ankerkräfte sind bedeutend kleiner, was kostengünstigere Fundamentierung ermöglicht. Zudem ist das Auffangnetz in der Montage und Unterhalt einfach.In the inventive safety net, in which the two support cables to the individual support bodies slidably guided in their longitudinal direction and are laterally guyed and the net in the support body area on Support bodies running past, attached to the suspension ropes Running cables is slidably held, the forces receiving ring mesh surface Significantly enlarged compared to conventional safety nets become. The safety net ensures optimum load distribution and a more favorable flow of forces through the network, and thus smaller Forces throughout the system. The anchor forces are also significant smaller, which allows more cost-effective foundation. Moreover, that is Safety net in the assembly and maintenance easy.

Dabei verlaufen die Laufseile 37, 38, 39, 40 bzw. 47, 48, 49, 50 frei an den Stützkörpern 7, 8, 9, 10 vorbei, und zwar vorzugsweise auf der dem Abhang oder der Felswand abgewandten Seite derselben, d.h. talseitig, wobei sie in Ausnahmefällen auch bergseitig angeordnet sein können.At the two support cables 3, 4 are each in the region of the support body 7, 8, 9, 10 running cables 37, 38, 39, 40 and 47, 48, 49, 50 attached, in such a way that - seen in the longitudinal direction of the network 2 - one end 37 a, 38a, 39a, 40a and 47a, 50a of the running rope 37, 38, 39, 40 and 47, 48, 49, 50 to one side of the respective support body 7, 8, 9, 10 and the other End 37b, 38b, 39b, 40b and 47b, 50b to the other side thereof. The running ropes 37, 38, 39, 40 and 47, 48, 49, 50 extend free on the support bodies 7, 8, 9, 10 over, preferably on the the slope or the rock face facing away from the same, i. valley side, and in exceptional cases they can also be arranged on the mountain side.

Das Netz 2 ist einerseits direkt an den Tragseilen 3, 4 verschiebbar gehalten, und zwar im Längsbereich zwischen Laufseilenden 37b, 38a; 38b, 39a; 39b, 40a zweier in Längsrichtung benachbarter Laufseile 37, 38, 39, 40 bzw. 47, 48, 49, 50, im Stützkörperbereich ist jedoch das Netz 2 an den jeweiligen Laufseilen 37, 38, 39, 40 bzw. 47, 48, 49, 50 verschiebbar gehalten und an den Stützkörpern 7, 8, 9, 10 vorbei geführt. Die verschiebbare Anordnung des Netzes 2 an den Tragseilen 3, 4 und auf den Laufseilen 37, 38, 39, 40 bzw. 47, 48, 49, 50, dank deren die Ringbündel des Netzes 2 wie bei einem Vorhang reihenweise auf den entsprechenden Seilen verschoben werden können, erfolgt mit Vorteil mittels um die randseitige Ringe und um das jeweilige Seil geschlaufter Gleitelemente 51.The network 2 is held on the one hand directly to the support cables 3, 4 slidably namely in the longitudinal region between running cable ends 37b, 38a; 38b, 39a; 39b, 40a of two longitudinally adjacent running cables 37, 38, 39, 40 and 47, 48, 49, 50, in the support body area, however, the network 2 to the respective running cables 37, 38, 39, 40 and 47, 48, 49, 50 slidably held and led to the support bodies 7, 8, 9, 10 over. The movable one Arrangement of the network 2 on the support cables 3, 4 and on the Running ropes 37, 38, 39, 40 and 47, 48, 49, 50, thanks to which the ring bundles of the network 2 like a curtain in rows on the corresponding Ropes can be moved, with advantage by means of the edge side Rings and around the respective rope looped sliding 51st

Die Laufseile 37, 38, 39, 40 bzw. 47, 48, 49, 50 sind an ihren Enden mit den Tragseilen 3, 4 mittels aus Fig. 1 und 2 nicht ersichtlicher Klemmelemente entweder fest verbunden oder an diesen gleitend angebracht, wobei die gleitende Bewegung der Laufseilenden auf den Tragseilen 3, 4 vorzugsweise ab einer definierten einstellbaren Belastung eingeleitet wird.The hoses 37, 38, 39, 40 and 47, 48, 49, 50 are at their ends with the support cables 3, 4 by means of Fig. 1 and 2 not apparent clamping elements either firmly connected or slidably attached to it, wherein the sliding movement of the cable ends on the support cables 3, 4 preferably is initiated from a defined adjustable load.

Wenn nun beispielsweise, wie in Fig. 1 dargestellt, ein Stein 15 in den sich zwischen den Stützkörpern 8, 9 befindenden Bereich des Netzes 2 fällt, werden vorerst die Ringbündel des Netzes 2 wie bei einem Vorhang auf den Tragseilen 3, 4 sowie auf den Laufseilen 38, 39, 48, 49 in Richtung zur Aufprallstelle hin geschoben, wodurch bereits ein Teil der dynamischen Energie absorbiert wird.If, for example, as shown in Fig. 1, a stone 15 in the between the support bodies 8, 9 located area of the network 2 falls, For the time being, the ring bundles of net 2 will be like a curtain the support cables 3, 4 and on the running cables 38, 39, 48, 49 in the direction pushed to the point of impact, which is already part of the dynamic Energy is absorbed.

Damit wird auch die mögliche Auslenkung des Netzes 2 begrenzt. Während dieser Phase kommen auch diejenigen Ringreihen zum Einsatz, die sich zuvor zu der anderen Seite der Stützkörper 8, 9 befanden und die nun an den Laufseilen 38, 39, 48, 49 ungehindert an den Stützkörpern 8, 9 vorbei bewegt werden können.But there are also on the supporting bodies 8, 9 slidably guided Support cables 3, 4 and thus also attached to the support cables 3, 4 Running ropes 38, 39, 48, 49 pulled down until the connection points the cable ends 38a, 39b on the support cable 3 and the corresponding connection points the running ropes 48, 49 with the supporting cable 4 to the supporting bodies 8, 9 arrive and at a fixed connection of the running cables 38, 39 or 48, 49 with the respective support cable 3 and 4, a further cable movement to stop. This also limits the possible deflection of the network 2. During this phase, also those rows of rings come to Insert, which were previously to the other side of the support body 8, 9 and now on the running ropes 38, 39, 48, 49 unhindered on the support bodies 8, 9 can be moved past.

Somit wird die mitwirkende Ringnetzfläche gegenüber den herkömmlichen Auffangnetzen mit fix an den Stützkörpern befestigten Tragseilen erheblich vergrössert. Befinden sich beispielsweise vor dem Aufprall, wie in Fig. 2 dargestellt, die Laufseilenden 38a, 38b bzw. 39a, 39b jeweils in einer Entfernung von 2 m zum Stützkörper 8 bzw. 9, so kommt bei 10m voneinander entfernten Stützkörpern 8, 9 beim Aufprall (Fig. 1) eine 14 m lange Ringnetzfläche zum Einsatz, d.h. eine um 40% grössere Ringnetzfläche als bei einem herkömmlichen Auffangnetz mit 10m voneinander entfernten Stützkörpern.Thus, the cooperating Ringnetzfläche compared to the conventional Safety nets with fixed fixed to the supporting bodies suspension cables considerably increased. Are for example, before the impact, as in Fig. 2, the running cable ends 38 a, 38 b and 39 a, 39 b respectively in one Distance of 2 m to the support body 8 or 9, so comes at 10m Support bodies 8, 9 remote from each other during impact (Fig. 1) a 14 m long ring net area is used, i. a 40% larger ring network area than in a conventional safety net with 10m apart Supporting bodies.

Durch die beim Aufprall auf das Netz 2 auf die Tragseile 3, 4 ausgeübten Zugkräfte werden die im seitlichen Bereich der Tragseile 3, 4 integrierten Bremsmittel 5, 6 wirksam, die weitere Energieabsorption bewirken. Die Anordnung der Bremsmittel 5, 6 im seitlichen Bereich, ausserhalb der Schutzzone, ist besonders vorteilhaft, da der Zugang zwecks Auswechselns besonders einfach ist.By the impact on the network 2 on the support cables 3, 4 exerted Tensile forces are integrated in the lateral area of the supporting cables 3, 4 Braking means 5, 6 effective, causing further energy absorption. The Arrangement of the braking means 5, 6 in the lateral region, outside the Protection zone, is particularly advantageous because access for replacement is particularly easy.

Das erfindungsgemässe Auffangnetz mit den beidseitig zu den Stützkörpern 7, 8, 9, 10 an längsbeweglichen Tragseilen 3, 4 angebrachten Laufseilen 37, 38, 39, 40 bzw. 47, 48, 49, 50 gewährleistet eine optimale Lastverteilung mit besserer Verteilung auf mehrere Stützkörper sowie einen günstigeren Kräftefluss durch das Netz 2, und somit kleinere Kräfte im gesamten System. Auch die Ankerkräfte sind bedeutend kleiner, was kürzere Ankerlängen und somit eine kostengünstigere Fundamentierung ermöglicht.The inventive safety net with the two sides of the support bodies 7, 8, 9, 10 attached to longitudinally movable carrying cables 3, 4 running ropes 37, 38, 39, 40 and 47, 48, 49, 50 ensures optimal load distribution with better distribution on several supporting bodies as well as a cheaper one Force flow through the network 2, and thus smaller forces throughout System. Also, the anchor forces are significantly smaller, which is shorter Anchor lengths and thus a more cost-effective foundation allows.

Werden - wie bereits erwähnt - die Laufseile 37, 38, 39, 40 bzw. 47, 48, 49, 50 nicht fest, sondern gleitend an den Tragseilen 3, 4 angebracht, derart, dass durch Reibung oder elastische und/oder plastische Verformung eine Art Bremswirkung erzeugt wird, so kann ab einer bestimmten Belastung während des Gleitens weitere Energie absorbiert werden.Are - as already mentioned - the running ropes 37, 38, 39, 40 and 47, 48, 49, 50 not fixed, but slidably attached to the support cables 3, 4, in such a way that by friction or elastic and / or plastic deformation a kind of braking effect is generated, so from a certain load while sliding more energy is absorbed.

In Fig. 3 ist der Aussenbereich eines annähernd vertikal ausgelegten Auffangnetzes 1' dargestellt, welches im Unterschied zu demjenigen nach Fig. 1 und 2 an einem Schräghang angeordnet ist und am Hang herunterstürzendes Material wie zum Beispiel Steine, auffängt. Es ist ein annähernd vertikal gerichteter äusserer Stützkörper 10' mit einem im Querschnitt runden Stützenkopf 10a' ersichtlich, an dem die Rückhalteseile 11' schonend gehalten sind.In Fig. 3 is the outside of an approximately vertically designed safety net 1 ', which differs from that of FIG. 1 and 2 is arranged on a slanted slope and falling down the slope Material such as stones, fields. It is an approximate vertically directed outer support body 10 'with a cross-section round support head 10a ', on which the retaining ropes 11' gentle are held.

Auf einer dem Hang zugewandten Seite des Stützenkopfes 10a' sind die bereits erwähnten Führungselemente für das obere, seitlich abgespannte Tragseil 3' angebracht, die mit 55 bezeichnet sind und die zum Schutze des verschiebbaren Tragseiles 3' rund sind. Ähnliche Führungselemente sind auch am unteren Ende des Stützkörpers 10' bei seiner Grundplatte für das untere Tragseil vorgesehen, die jedoch aus Fig. 3 nicht ersichtlich sind. Am Tragseil 3' ist mittels Klemmelementen 56, von denen lediglich eines ersichtlich ist, ein Laufseil 40' angebracht, welches im Gegensatz zum Tragseil 3' auf der anderen Seite des Stützkörpers 10' verläuft, so dass das mittels Gleitelementen 51' auf dem Laufseil 40' verschiebbar geführte Netz 2' auf der Talseite, vor dem Stützkörper 10', angeordnet ist. Das Netz 2' ist im übrigen im Bereich innerhalb des Laufseiles 40' mit einigen aussenseitigen Elementen via die Gleitelemente 51' direkt am Tragseil 3' befestigt. Damit wird eine Positionierung des Netzes 2' am oberen Ende beim Stützkörper 10' ermöglicht. Es ist damit verdeutlicht, dass im Bereich des Tragseiles 3', welches durch die beiden an ihm befestigten Enden des Laufseiles 40' begrenzt ist, das Netz mit einzelnen Gleitelementen 51' befestigt sein kann oder aber auch nicht, wie dies beim Netz gemäss Fig. 1 vorgesehen ist.On a side facing the slope of the column head 10a 'are the already mentioned guide elements for the upper, laterally untensioned Support cable 3 'attached, which are designated 55 and the protection of the displaceable support cable 3 'are round. Similar guide elements are also at the lower end of the support body 10 'at its base plate for provided the lower support cable, but not apparent from Fig. 3 are. On the support cable 3 'is by means of clamping elements 56, of which only one can be seen, a tether 40 'attached, which in contrast to the support cable 3 'on the other side of the support body 10', so that guided by sliding elements 51 'on the running cable 40' slidably Net 2 'on the valley side, in front of the support body 10', is arranged. The network 2 'is in the rest in the area within the running cable 40' with some outside elements via the sliding elements 51 'directly on Supporting cable 3 'attached. This is a positioning of the network 2 'on upper end of the support body 10 'allows. It makes it clear that in the region of the supporting cable 3 ', which by the two attached to him Ends of the tether 40 'is limited, the network with individual sliding elements 51 'may be attached or not, as in the network 1 is provided according to FIG.

Gemäss Fig.4 können die Laufseile 62 im Ausgangszustand aber auch durch als Sollbruchstellen gestaltete Führungselemente 60, die jeweils an der Unterseite 70' des Stützkörper-Endes 70 angebracht sind, gehalten sein. Als Führungselemente 60 sind vorliegend zwei mit Distanz zueinander am Stützkörper befestigte Elemente 63, 64 sowie ein von diesen gehaltener, die Sollbruchstelle bildender Bolzen 65 vorgesehen, auf welchem das Laufseil 62 aufliegt. Bei Erreichen einer bestimmten Sollbruchlast wird dieser Bolzen 65 abgebrochen und damit senkt sich das Laufseil 62 zu den Stützkörpern ab, derart, wie dies dann in Fig. 1 ersichtlich ist. Es ist ferner noch das an der Stirnseite des Stützkörpers 70 mittels Befestigungselementen 67, 68 gehaltene Tragseil 66 veranschaulicht.According to Figure 4, the running ropes 62 in the initial state but also by designed as predetermined breaking points guide elements 60, each at the underside 70 'of the support body end 70 are mounted be. As guide elements 60 are present two with distance from each other attached to the support body elements 63, 64 and a held by these, the predetermined breaking point forming bolt 65 is provided, on which the running rope 62 rests. Upon reaching a certain breaking load this bolt 65 is broken off and thus the running rope 62 lowers to the support bodies, so, as can be seen in Fig. 1 then. It is Furthermore, that still on the front side of the support body 70 by means of fastening elements 67, 68 held carrying cable 66 illustrated.

Die am Laufseil gleitenden Ringreihen des Netzes, die in Fig.4 nicht dargestellt sind, können sich erst nach dem Zerstören dieses Bolzens 65 ungehindert an dem jeweiligen Stützkörper 8, 9 vorbei bewegen. Solange der Bolzen 65 vom Laufseil 62 nicht durch Biegen zerstört worden ist, sind die Ringe von diesem Bolzen 65 zurückgehalten.The sliding on the cable ring rows of the network, not shown in Figure 4 are, can only after the destruction of this bolt 65 unhindered move past the respective support body 8, 9 over. As long as the Bolt 65 has not been destroyed by the running rope 62 by bending are the rings are retained by this bolt 65.

Selbstverständlich könnte für Systeme im höheren Energiebereich sowohl das Auffangnetz 1 nach Fig.2 und 3 als auch das Auffangnetz 1' nach Fig. 3 mit zusätzlichen, das Ringnetz und/oder die Laufseile mit den Stützkörpern verbindenden und mit Bremselementen versehenen Verbindungselementen, wie sie aus der EP-A-1 205 603 bekannt sind, ausgestattet sein.Of course, for higher energy systems both the safety net 1 according to Figures 2 and 3 and the safety net 1 'of FIG. 3 with additional, the ring network and / or the running cables with the supporting bodies connecting and provided with braking elements fasteners, as are known from EP-A-1 205 603, be equipped.

Für Systeme im niedrigen Energiebereich genügen jedoch beim erfindungsgemässen Auffangnetz die im seitlichen Bereich der Tragseile vorgesehenen Bremsringe aus, und zwar total nur acht Bremsringe pro ca. 40 bis 50 m Verbauung.For systems in the low energy range, however, suffice in the inventive Safety net provided in the lateral area of the suspension ropes Brake rings out, and totally only eight brake rings per about 40 up to 50 m of obstruction.

Die Erfindung ist mit den obigen Ausführungsbeispielen ausreichend dargetan. Sie könnte jedoch noch anders ausgestaltet sein. Anstelle des Laufseiles könnten im Prinzip auch Stangen oder Bänder verwendet werden. Der Begriff des Laufseiles ist daher entsprechend auch auf solche Ausführungen zu verstehen. Es könnten auch mehrere Laufseile an einer Stelle vorhanden sein.The invention is sufficiently demonstrated with the above embodiments. However, it could be designed differently. Instead of the running rope In principle, rods or ribbons could also be used. The term of the running rope is therefore correspondingly also to such embodiments to understand. There could also be several running ropes in one place to be available.

Das Netz, das Laufseil und das Tragseil liesse sich alternativ auch bergseitig anordnen. Es müsste dann einzig sichergestellt sein, dass sich das Netz und die Seile zu den Stützkörpern verschieben können. Selbstverständlich könnte auch nur ein Rückhalteseil 11 pro Stützkörper vorgesehen sein.The net, the running rope and the carrying rope could alternatively also be on the mountain side Arrange. It would then only have to be sure that the network and move the ropes to the supporting bodies. Of course could also be provided only one retaining rope 11 per support body.

Im Prinzip könnten beispielsweise bei dem Netz nach Fig. Laufseile auch nur bei den inneren Stützkörpern 8, 9 vorgesehen sein und nicht bei den äusseren Stützkörpern 7, 10. Die Laufseile könnten insbesondere endseitig auch mit Bremsringen oder Bremsmitteln ausgestattet sein.In principle, for example, in the network according to FIG be provided only at the inner support bodies 8, 9 and not in the outer support bodies 7, 10. The running cables could in particular end also be equipped with brake rings or braking means.
