Description

Die Erfindung betrifft eine Stütze einer Steinschlagverbauung gemäß dem Oberbegriff des Anspruches 1.The invention relates to a support of a Steinschlagverbauung according to the preamble of claim 1.

Eine derartige Stütze ist aus der EP 1 911 884 A1 bekannt. Steinschlagverbauungen werden beispielsweise an Berghängen installiert und weisen neben einer Mehrzahl von gattungsgemäßen Stützen eine Fangnetzanordnung auf, die über Trag- und Mittelseile an den Stützen geführt ist.Such a support is from the EP 1 911 884 A1 known. Rockfall barriers are installed, for example, on mountain slopes and, in addition to a plurality of generic supports on a safety net arrangement, which is guided via support and center cables on the supports.

Um die auf die Steinschlagverbauung einwirkenden Kräfte aufzunehmen, sind die Stützen u.a. mittels bergseitiger Rückhalteseile gehalten, die an einem Ende am Stützenkopf angreifen und an ihrem anderen Ende beispielsweise über Bodenanker (Zuganker oder kombinierte Druck-/Zuganker) im Untergrund fixiert werden.In order to absorb the forces acting on the Steinschlagverbauung forces, the supports u.a. held by means of mountain-side restraint ropes which engage at one end on the column head and at its other end, for example, via ground anchors (tie rods or combined pressure / tension anchor) are fixed in the ground.

Es ist Aufgabe der vorliegenden Erfindung, eine Stütze der im Oberbegriff des Anspruches 1 angegebenen Art zu schaffen, die eine Minimierung bzw. zumindest Reduzierung der auftretenden Ankerkräfte ermöglicht.It is an object of the present invention to provide a support of the type specified in the preamble of claim 1, which enables minimization or at least reduction of the occurring armature forces.

Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruches 1.The solution of this object is achieved by the features of claim 1.

Dementsprechend ist erfindungsgemäß vorgesehen, dass am Stützenkopf eine Seilumlenkeinrichtung vorgesehen ist, über das bzw. die Seile einer Abspannseilanordnung geführt werden können. Ein Ende des Seile bzw. die Enden der Seile, falls die Abspannseilanordnung mehrere Seile aufweist, sind hierbei an einem ersten Bodenanker angebracht, der auf der Bergseite, also oberhalb der Stütze im Hang fixiert ist. Das andere über die Seilumlenkeinrichtung geführte Ende des Seile (bzw. der Seile) wird an einem zweiten Bodenanker angebracht, der je nach der Art der Ausführungsform, die nachfolgend im Einzelnen beschrieben werden, talseitig, also unterhalb der Stütze bzw. ebenfalls bergseitig, im Untergrund fixiert sind.Accordingly, the invention provides that on the column head a Seilumlenkeinrichtung is provided, via which or the ropes of a guy rope arrangement can be performed. One end of the rope or the ends of the ropes, if the guy rope arrangement has a plurality of cables, are in this case attached to a first ground anchor, which is fixed on the mountain side, ie above the support in the slope. The other guided over the Seilumlenkeinrichtung end of the rope (or ropes) is attached to a second ground anchor, depending on the type of embodiment, which will be described in detail below, the valley, ie below the support or also on the mountain side, in the underground are fixed.

Die Unteransprüche haben vorteilhafte Weiterbildungen der Erfindungen zum Inhalt.The dependent claims have advantageous developments of the inventions to the content.

Aus der EP 1 036 884 A2 ist zwar eine Schutzverbauung zum Schutz eines Objektes und zum Ableiten von sich zu Tal wälzenden Volumenmassen, insbesondere Schnee-Muren oder Geröllmassen oder Steinschlag, bekannt, bei welcher oberhalb des Schutzobjektes ein erster Ankerpunkt vorgesehen ist, von dem ausgehend zumindest ein, vorzugsweise zwei sich erhebende nachgiebige Flächenbereiche sich unter Verlängerung und Verbreiterung zu Tal gerichtet erstrecken und bei welcher ein Hauptseilbündel in einem Hochpunkt der Stütze umgelenkt und über weitere Seilbündel zu Rückverankerungspunkten geführt wird. Jedoch liegen diese Rückverankerungspunkte weit entfernt vom Stützenfuß. Diese Anordnung der Rückverankerungspunkte ist bei dieser Schutzverbauung aufgrund der zeltähnlichen Aufspannung der nachgiebigen Flächenbereiche zwingend erforderlich.From the EP 1 036 884 A2 Although a Schutzverbauung for the protection of an object and for deriving from rolling to Tal volume masses, especially snow-muds or boulders or rockfall, known, in which above the object to be protected, a first anchor point is provided, starting from which at least one, preferably two uplifting compliant areas extend under extension and widening directed to valley and in which a main rope bundle is deflected at a high point of the support and guided over other rope bundles to Rückverankerungspunkten. However, these anchoring points are far away from the column foot. This arrangement of the Rückverankerungspunkte is mandatory in this Schutzverbauung due to the tent-like clamping of the resilient surface areas.

Wie zuvor bereits erläutert, kann die Abspannseilanordnung lediglich ein Seil aufweisen, das vom bergseitigen Bodenanker (Zuganker) zum Stützenkopf und über die Seilumlenkeinrichtung zum Stützenfuß geführt wird. Bei einer Ausführungsform ist das fußseitige Ende des Seiles der Abspannseilanordnung mit einem Bodenanker verbindbar, der talseitig, also unterhalb der Stütze im Untergrund fixiert wird.As already explained above, the guy rope arrangement can only comprise a cable which is guided by the mountain-side ground anchor (tie rod) to the column head and via the cable deflection device to the column foot. In one embodiment, the foot-side end of the rope of the guy rope assembly is connectable to a ground anchor, which is fixed in the ground, so below the support in the ground.

Bei einer alternativen Ausführungsform weist die Abspannseilanordnung pro Stütze ebenfalls lediglich ein Seil auf, das bergseitig, also oberhalb der Stütze, mit seinem ersten Ende wiederum über einen Bodenanker im Untergrund fixiert ist, dann allerdings über die am Stützenkopf angeordnete Seilumlenkeinrichtung zum Stützenfuß auf der Bergseite der Stütze, also oberhalb der Stütze geführt und dort gegebenenfalls nochmals über eine zweite Umlenkeinrichtung zu einem Bodenanker geführt wird.In an alternative embodiment, the guy rope assembly per support also only a rope on the mountain side, so above the support, in turn fixed with its first end via a ground anchor in the ground, but then on the column head arranged Seilumlenkeinrichtung for Stützfußfuß on the mountain side of Support, that is guided above the support and there optionally again via a second deflection to a ground anchor is performed.

Bei einer weiteren denkbaren alternativen Ausführungsform ist es möglich, zwei Seile pro Stütze und Abspannseilanordnung vorzusehen, von denen eines mit seinem zweiten Ende talseitig und das andere im Bereich des Stützenfußes bergseitig, wie zuvor erläutert, angeordnet und fixiert wird.In a further conceivable alternative embodiment, it is possible to provide two ropes per support and guy rope arrangement, one of which is arranged and fixed at the valley side with its second end and the other in the region of the column foot, as explained above.

Bei einer weiteren denkbaren Ausführungsform ist es möglich, pro Stütze und Abspannseilanordnung zwei parallel auf gleicher Höhe geführte Seile vorzusehen, deren erste Enden wiederum bergseits der Stütze fixiert sind, während die zweiten Enden talseits der Stütze im Untergrund fixiert werden können. In diesem Falle weist die Seilumlemkeinrichtung zwei seitlich der Stütze am Stützenkopf angeordnete Umlenkrollen auf gleicher Höhe auf, über die die Seile geführt werden. In diesem Falle werden die jeweils zweiten Enden der beiden Seile beiderseits des Stützenfußes über Bodenanker und ggf. Energieabsorbierungseinrichtungen zumindest in etwa mittig des Stützenfußes im Untergrund fixiert.In a further conceivable embodiment, it is possible to provide per support and guy rope two parallel guided at the same height ropes, the first ends are in turn fixed on the mountain side of the support, while the second ends can be fixed tal talseits the support in the ground. In this case, the Seilumlemkeinrichtung two arranged laterally of the support on the column head deflection rollers at the same height over which the ropes are performed. In this case, the respective second ends of the two cables are fixed on both sides of the column foot via ground anchors and possibly energy absorbing devices at least approximately in the center of the column foot in the ground.

Die freien Enden dieser Seilanordnungen können zusammengefasst über einen Bodenanker oder getrennt über zwei Bodenanker fixiert werden.In the embodiments according to the FIGS. 3C to 3F Lashing cable assemblies 8 are provided, each comprising two ropes, which are accordingly deflected in each case via a Seilumlenkeinrichtung 11 with two deflection points, so for example two pulleys. The embodiments according to the Figures 3C and 3D correspond in principle to those of FIGS. 3A and 3B , wherein, as said, two ropes each form a guy rope arrangement. The free ends of these cable arrangements can be summarized via a ground anchor or separately fixed over two ground anchors.

Bei der Ausführungsform gemäß Figur 3E weist die Seilumlenkeinrichtung 11 zwei Umlenkpunkte auf, die seitlich der Stütze 1 bzw. des Stützenkopfes 2 vorgesehen sind.In the embodiment according to FIG. 3E has the Seilumlenkeinrichtung 11 two deflection points, which are provided laterally of the support 1 and the support head 2.

Bei der Ausführungsform gemäß Figur 3F ist eine Seilumlenkeinrichtung 11 auf der hangaufwärts weisenden Seite 7 und die andere auf der hangabwärts weisenden Seite 6 angeordnet, wie sich dies im einzelnen aus der zeichnerischen Darstellung ergibt.In the embodiment according to FIG. 3F a Seilumlenkeinrichtung 11 is arranged on the uphill side facing 7 and the other on the downhill side 6, as this results in detail from the drawing.

Bei den Ausführungsformen gemäß den Figuren 3G und 3H ist eine Abspannseilanordnung 8 vorgesehen, die von zwei im Wesentlichen v-förmigen geführten Seilen in einen Seilabschnitt 8C überführt wird, der dann jeweils über eine Seilumlenkeinrichtung 11 im einen Falle auf der hangaufwärts weisenden Seite 7 und im Falle der Figur 3H auf der hangabwärts weisenden Seite 6 der Stütze 1 umgelenkt wird.In the embodiments according to the Figures 3G and 3H a guy rope assembly 8 is provided, which is transferred from two substantially V-shaped guided ropes in a cable section 8C, which then in each case via a Seilumlenkeinrichtung 11 in a case on the uphill side 7 and in the case of FIG. 3H is deflected on the downhill side 6 of the support 1.

Die Figuren 3I und 3J stellen Ausführungsformen dar, bei denen die Abspannseilanordnung 8 zuerst v-förmig zusammenlaufende Seilabschnitte und dann parallel zueinander verlaufende Seilabschnitte aufweisen, jedoch über jeweils zwei Seilumlenkeinrichtungen bzw. zwei Umlenkrollen einmal auf der hangaufwärts weisenden Seite 7 und im Falle der Figur 3J auf der hangabwärts weisenden Seite 6 umgelenkt werden.The FIGS. 3I and 3J represent embodiments in which the guy rope assembly 8 have first V-shaped converging cable sections and then parallel to each other cable sections, but via two Seilumlenkeinrichtungen or two pulleys once on the uphill side facing 7 and in the case of FIG. 3J be redirected on the downhill side 6.

Bei der Ausführungsform gemäß Figur 3K weist die Abspannseilanordnung 8 ebenfalls zwei Seile auf, wobei das Seil 8E über eine auf der hangaufwärts weisenden Seite 7 angeordneten Seilumlenkeinrichtung 11 umgelenkt wird, während das Seil 8 der Abspannseilanordnung 8 auf der hangabwärts weisenden Seite 6 über eine Umlenkeinrichtung 11 umgelenkt wird.In the embodiment according to Figure 3K the guy rope assembly 8 also has two ropes, wherein the rope 8E is deflected over a cable guide 11 arranged on the uphill side 7, while the rope 8 of FIG Abspannseilanordnung 8 is deflected on the downhill side 6 via a deflecting device 11.

Die Ausführungsform gemäß der Figur 3L zeigt schließlich eine Abspannseilanordnung mit Seilen 8F bzw. 8G, die jeweils über Seilumlenkeinrichtungen 11 umgelenkt werden, die in etwa mittig der Stütze 1 neben dem Stützenkopf 2 angeordnet sind und von dort die Seile 8F und 8G in den Hang umleiten, die seitlich des Stützenfußes 4 im Untergrund münden.The embodiment according to the FIG. 3L Finally shows a guy rope arrangement with ropes 8F and 8G, which are respectively deflected by Seilumlenkeinrichtungen 11, which are arranged approximately in the middle of the support 1 next to the support head 2 and from there reroute the ropes 8F and 8G in the slope, the side of the column foot 4th in the underground.

In jedem Falle wird bei jeder der erläuterten Ausführungsformen eine Reduzierung der Ankerkräfte erreicht, da nicht nur ein bergseitiges Rückhalteseil (was den Seilabschnitten 8A bzw. 8'A entspräche) vorgesehen ist, sondern eine Abspannseilanordnung 8 mit Seilumlenkeinrichtung 11 und/oder 14, wie sie zuvor entsprechend den unterschiedlichen Ausführungsformen erläutert worden ist.In any case, in each of the illustrated embodiments, a reduction in the armature forces is achieved because not only a mountain-side restraining rope (which would correspond to the rope sections 8A and 8'A, respectively) is provided, but a guy rope assembly 8 with rope deflector 11 and / or 14, as they are previously explained according to the different embodiments.

Neben der voranstehenden schriftlichen Offenbarung der Erfindung wird hiermit explizit auf deren zeichnerische Darstellung in der einzigen Figur Bezug genommen.In addition to the above written disclosure of the invention, reference is hereby explicitly made to the drawings in the single figure.
