Abstract
Die vorliegende Erfindung betrifft eine Schutzverbauung (23) mit einer Vorrichtung (1) zur Energiedissipation, die aufweist: ein Bremsprofil (2); und eine Schneideinheit (3), die zumindestens eine Schneide (4A, 4B) aufweist, die entlang der Längsachse (L) des Bremsprofils (2) durch dieses hindurchziehbar ist.The present invention relates to a protective barrier (23) having a device (1) for energy dissipation, comprising: a braking profile (2); and a cutting unit (3) having at least one cutting edge (4A, 4B) which is extendable therethrough along the longitudinal axis (L) of the braking profile (2).
Description
Die Erfindung betrifft eine Schutzverbauung gemäß Anspruch 1.The invention relates to a protective barrier according to
Eine gattungsgemäße Vorrichtung ist aus der
Der Nachteil dieser bekannten Vorrichtung ist zunächst in einem relativ hohen baulichen Aufwand zu sehen, der vor allem darin begründet ist, dass zur Energieaufnahme eine Umbiegung bzw. Umlenkung des Zwischenstückes über das Umlenkelement erfolgt, wobei zur Aufrechterhaltung des Umlenkwinkels eine besondere Vorrichtung vorgesehen sein muss, die beispielsweise aus zwei Führungszapfen bestehen kann. Des Weiteren haben im Rahmen der Erfindung durchgeführte Untersuchungen ergeben, dass trotz des Zieles der gattungsgemäßen Druckschrift, den Stoß-Dämpfungsverlauf besser zu definieren bzw. zu optimieren hier weiterer Verbesserungsbedarf insbesondere beim Eintrag hoher Lasten in das Seil gegeben ist.The disadvantage of this known device is initially to be seen in a relatively high structural complexity, which is mainly due to the fact that for energy absorption, a bend or deflection of the intermediate piece via the deflecting takes place, to maintain the deflection angle a special device must be provided which may for example consist of two guide pins. Furthermore, investigations carried out within the scope of the invention have shown that, despite the aim of the generic document, to better define or optimize the shock-damping curve, further improvement is required in particular when high loads are introduced into the cable.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Schutzverbauung gemäß dem Oberbegriff des Anspruches 1 zu schaffen, bei der eine zumindestens weitgehend lineare Energieaufnahme der in das Seil eingebrachten Lasten gewährleistet ist.It is therefore an object of the present invention to provide a protective barrier according to the preamble of
Die Lösung dieser Aufgabe erfolgt durch die Merkmale des Anspruches 1. Die Unteransprüche haben vorteilhafte Weiterbildungen der Erfindung zum Inhalt.The solution of this object is achieved by the features of
Zu den Vorteilen der Erfindung zählt der Umstand, dass die bauliche Ausgestaltung der erfindungsgemäßen Vorrichtung einfacher ausgeführt werden kann, da beispielsweise keine Einrichtungen zur Aufrechterhaltung eines Umlenkwinkels erforderlich sind, da die Schneideinheit geradlinig und damit umlenkungsfrei durch das Bremsprofil hindurchgeführt bzw. vom Seil bei Aufbringung einer Zugkraft hindurchgezogen wird.Among the advantages of the invention is the fact that the structural design of the device according to the invention can be made simpler, since, for example, no means for maintaining a deflection angle are required because the cutting unit straight and thus without deflection passed through the brake profile or the rope when applying a Traction is pulled through.
Die erfindungsgemäße Schutzverbauung kann gegen Steinschlag, Holzschlag, Lawinen oder Ähnlichem (wie z. B. auch als Fangzaun von Autorennstrecken), eingesetzt werden.The protective barrier according to the invention can be used against stone chipping, felling, avalanches or the like (such as, for example, as a safety fence of car racing tracks).
Eine derartige Schutzverbauung weist üblicherweise eine Stützstruktur auf, die je nach Verbaulänge eine Mehrzahl beabstandeter, an einem Hang fixierbarer, Stützen umfasst. An den Stützen ist ein Netz, das vorzugsweise mit einer Geflechtsauflage versehen sein kann, befestigt. Hierfür ist ein oberes und ein unteres Tragseil vorgesehen. Das obere Tragseil führt das Netz im Bereich von Stützenköpfen der Stützen und das untere Tragseil führt das Netz im Bereich des Stützenfußes. Seitlich des Netzes sind die oberen und unteren Tragseile über Felsanker im Untergrund befestigt, wobei in diesem Bereich sowie vorzugsweise auch im Bereich des Netzes, die erfindungsgemäßen Energiedissipationsvorrichtungen vorgesehen sein können. Vom Prinzip her ist es auch möglich, als Stützstruktur nur ein Seil oder mehrere Seile zu verwenden, das bzw. die das Netz aufspannt/aufspannen.Such a protective barrier usually has a support structure which, depending on the length of the installation, comprises a plurality of spaced pillars which can be fixed on a slope. On the supports, a network, which may be preferably provided with a braid, attached. For this purpose, an upper and a lower suspension cable is provided. The upper suspension cable carries the net in the area of column heads of the supports and the lower suspension cable guides the net in the area of the column foot. Laterally of the network, the upper and lower support cables are fastened by means of rock anchors in the ground, wherein in this area and preferably also in the region of the network, the invention Energiedissipationsvorrichtungen can be provided. In principle, it is also possible to use as a support structure only a rope or more ropes that spans or span the net.
Bei einer besonders bevorzugten Ausführungsform sind zwischen dem oberen Tragseil und dem unteren Tragseil ein oder mehrere Mittelseile vorhanden, die mit dem Netz, beispielsweise durch ein Hindurchschlaufen, verbunden sein können. Die Verbindung kann hierbei über die gesamte Verbaulänge durchgängig erfolgen oder im Bereich des Verlaufes der Mittelseile über die Träger der Stützstruktur ausgelassen sein, wobei also dann die beispielhaft genannte Durchschlaufung in diesen Bereichen nicht erfolgt.In a particularly preferred embodiment, one or more center ropes are provided between the upper support cable and the lower support cable, which can be connected to the net, for example by a loop through. In this case, the connection can be made continuously over the entire length of the connection or can be omitted in the region of the course of the middle ropes on the support of the support structure, in which case the example looping through in these areas does not occur.
Die Mittelseile verlaufen über die gesamte Verbaulänge und werden ebenfalls seitlich der äußersten Träger der Schutzverbauung im Untergrund fixiert, wobei hier wiederum vorzugsweise Felsanker vorgesehen sein können, in deren Bereich Energiedissipationvorrichtungen bzw. Seilbremsen vorgesehen sein können, die entsprechend den Prinzipien vorliegender Erfindung ausgebildet sind.The middle ropes run over the entire length of the installation and are also fixed laterally of the outermost support of Schutzverbauung in the ground, here again preferably rock anchors can be provided in the field energy dissipation devices or rope brakes can be provided, which are formed according to the principles of the present invention.

Die Einlaufbereiche 8A, 8B können hierbei sowohl spitz als auch stumpf zulaufend ausgebildet sein. Unter "spitz zulaufend" ist hierbei zu verstehen, dass ein Zulaufbereich, wie bei einem spitzen Winkel, geschaffen wird, während "stumpf zulaufend" bedeuten würde, dass der Zulaufbereich zumindest leicht gerundet ausgebildet sein kann.The above-described particularly preferred embodiment of the
