Description

Die Erfindung betrifft ein Anschlusssystem zwischen einer weiterführenden Schutzeinrichtung und einem davor angeordneten Anpralldämpfer.The invention relates to a connection system between a continuing protection device and an impact absorber arranged in front of it.

Anschlusssysteme zwischen zwei weiterführenden Schutzeinrichtungen unterschiedlicher Bau- und Konstruktionsart sind im Stand der Technik bekannt. Bei diesen Schutzeinrichtungen unterschiedlicher Bau- und Konstruktionsart handelt es sich zum einen um Leitplankenkonstruktionen aus Metall mit Zugbandeigenschaften und zum anderen um Konstruktionen aus Beton. Bei diesen Konstruktionen wurde ein Übergangsblech an die Betonkonstruktion angeformt und mit den Schutzplanken sowie der Betonwand verbunden. Die Zugband - Ausbildungen wurden lediglich aneinander angeschlossen.Connection systems between two further protective devices of different construction and construction types are known in the prior art. These guards of different construction and construction are on the one hand guard structures made of metal with Zugbandeigenschaften and on the other constructions made of concrete. In these constructions, a transition panel was molded to the concrete structure and connected to the crash barriers and the concrete wall. The tieback trainings were merely connected to each other.

Bei der vorliegenden Erfindung wird jedoch ein Anpralldämpfer an eine weiterführenden Schutzeinrichtung angeschlossen, wobei zwei Problem zu bewältigen sind: der Anpralldämpfer muss neben seiner Aufgabe, ein aufprallendes Fahrzeug soweit abzudämpfen, dass die Insassen keinen Schaden nehmen, auch ein seitlich auftreffende Fahrzeuge sicher ableiten. Gleichzeitig muss aber auch die weiterführende Schutzeinrichtung ihre Aufgabe als Zugband über ihre gesamte Länge hinweg erfüllen. Hierzu weist sie üblicher Weise an ihren Enden eine im Erdreich verankerte Absenkung auf, die die bei einem seitlichen Anprall auftretenden Zugkräfte in den Untergrund einleitet. Wenn jedoch ein Anpralldämpfer vor einer weiterführenden Schutzeinrichtung angeordnet ist, kann eine Absenkung nicht ausgeführt werden.In the present invention, however, a crash cushion is connected to a secondary protection device, with two problems to deal with: the impact damper in addition to its task to cushion an impacting vehicle so far that the occupants take no damage, safely divert a laterally impinging vehicles. At the same time, however, the secondary protection device must also do its job as a drawstring over its full length. For this purpose, it usually has at its ends an anchored in the ground subsidence, which initiates the tensile forces occurring in a lateral impact in the ground. However, if an impact absorber is placed in front of a secondary protection device, a lowering can not be carried out.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Anschlusssystem zu schaffen, bei dem die Zugbandfunktionen beider Einrichtungen, nämlich sowohl die der weiterführenden Schutzeinrichtung als auch die des Anpralldämpfers voll funktionsfähig sind.The invention is therefore based on the object to provide a connection system in which the Zugbandfunktionen both devices, namely both the continuing protection device and the impact absorber are fully functional.

Die Aufgabe wird bei einem Anschlusssystem zwischen einer weiterführenden Schutzeinrichtung und einem davor angeordneten Anpralldämpfer dadurch gelöst, dass an der Schutzeinrichtung eine Anschlussplanke angeordnet ist und ein formschlüssiges Verbindungselement zwischen der Anschluss-Planke der Schutzeinrichtung und dem letzten Anpralldämpferelement angeordnet ist und straßenseitlich der Anschlussplanke und zwischen dieser und dem formschlüssigen Verbindungselement mindestens ein Übergangsdämpfungselement angeordnet ist.The problem is solved in a connection system between a secondary protection device and an impact absorber disposed in front of it, that a connection plank is arranged on the protective device and a positive connection element between the connection plank of the protection device and the last crash cushion element is arranged and street side of the connection plank and between them and the positive connection element at least one transition damping element is arranged.

Dabei ist vorgesehen, dass an der weiterführenden Schutzeinrichtung zumindest eine Abspannung in Richtung Anpralldämpfer führt und im Endbereich des Anpralldämpfers im Boden verankert ist.It is provided that leads to the secondary protection device at least one bracing in the direction of impact absorbers and is anchored in the end of the crash cushion in the ground.

Der Anpralldämpfer steht auf einem Betonfundament und die mindestens eine Abspannung ist im Betonfundament verankert.The impact absorber stands on a concrete foundation and the at least one bracing is anchored in the concrete foundation.

Stellt die weiterführende Schutzeinrichtung ein höheres Rückhaltevermögen durch mindestens zwei Schutzplanken bereit, dann ist jede Schutzplanke mit einer eigenen Abspannung versehen.If the additional protective device provides a higher retention capacity through at least two protective barriers, then each protective barrier is provided with its own bracing.

Die Anschlussplanke ist eine Verlängerung einer unteren Schutzplanke der weiterführenden Schutzeinrichtung und im Endbereich letzterer straßenabgewandt abgebogen. Sie bildet mit dem Verbindungselement von oben gesehen einen Freiraum zur Aufnahme des mindestens einen Übergangsdämpfungselements.The connection plank is an extension of a lower guardrail of the secondary protection device and in the end area of the latter facing away from the road bent. It forms with the connecting element seen from above a space for receiving the at least one transition damping element.
