Description

Die Erfindung betrifft einen Schutzplankenanpralldämpfer zur Verwendung vor Hindernissen an Kraftfahrzeug-Verkehrswegen mit einer Vielzahl vor einer Betonabstützung angeordneten Dämpfelementen, die untereinander durch eine die Aufprallenergie absorbierende Vorrichtung verbunden sind.The invention relates to a crash barrier crash barrier for use in front of obstacles on motor vehicle traffic routes with a large number arranged in front of a concrete support Damping elements, which are caused by the impact energy absorbent device are connected.

Eine gattungsgemäße Vorrichtung zum Verbinden von Dämpfelementen ist aus der US-A-3,845,936 bekannt. Die Druckschrift zeigt mehrere Schutzplankenanpralldämpfer mit davor aufgereihten Dämpfelementen auf. Die Dämpfelemente sind in Verkehrsrichtung sowie quer zur Verkehrsrichtung miteinander verbunden. Direkt benachbarte Dämpfelemente sind an ihrer Ober- und Unterseite über ein aufgestecktes U, eine Schraube und ein keilförmiges Gegenstück fest miteinander verklemmt. Die Dämpfelemente, die senkrecht zur Verkehrsrichtung gesehen beabstandet sind, sind miteinander über zwei teleskopartig ineinander gleitende Profilstähle miteinander verbunden. Die Gleitbewegung wird durch eine Schraube und ein Gegenstück innerhalb der Profilstähle, welche durch die Schraube und durch eine Feder an eine Wand der ineinandergleitenden Profilstähle gepreßt werden, erschwert. Zusätzlich ist noch ein Anschlag gegen ein völliges Auseinanderziehen der beiden Profilstähle am umgebenden Profilstahl ausgebildet.A generic device for connecting damping elements is known from US-A-3,845,936. The publication shows several crash barrier crash absorbers with in front lined up damping elements. The damping elements are in Direction of traffic and with each other across the direction of traffic connected. Directly adjacent damping elements are on hers Top and bottom over an attached U, one Screw and a wedge-shaped counterpart firmly together jammed. The damping elements that are perpendicular to the direction of traffic seen spaced are over each other two profile steels that slide into each other telescopically connected. The sliding movement is controlled by a Screw and a counterpart within the section steels, which by a screw and by a spring on a wall the interlocking profile steels are pressed, difficult. In addition there is an attack against a complete one Pull apart the two section steels on the surrounding one Profile steel trained.

Durch die Verbindung zweier beabstandeter Dämpfelemente durch zwei ineinandergeschobene Profilstähle und durch Verklemmen der Profilstähle über eine Schraube unter einem innerhalb der Profilstähle liegenden Gegenstück wird eine nahezu steife Verbindung der Dämpfelemente geschaffen. Bei einem frontalen Aufprall eines Fahrzeugs auf den Schutzplankenanpralldämpfer weichen die Dämpfelemente speziell im Kopfbereich zur Seite aus. Über die beschriebene Verbindungsvorrichtung wird somit zusätzlich Aufprallenergie absorbiert. Um möglichst viel Aufprallenergie absorbieren zu können, müssen die beiden Profilstähle möglichst weit ineinandergeschoben sein.By connecting two spaced damping elements through two interlocking profile steels and by jamming the section steels over a screw under one inside of the profile steel lying counterpart is almost a stiff connection of the damping elements created. At a frontal impact of a vehicle on the crash barrier soft the damping elements especially in Head area to the side. About the connection device described impact energy is thus additionally absorbed. To absorb as much impact energy as possible the two section steels have to be pushed as far as possible be.

Bei einem seitlichen Aufprall hat diese Verbindungseinrichtung jedoch den Nachteil, daß die Profilstähle sofort auf Anschlag zusammengeschoben werden und somit eine sehr starre Verbindung der beiden Dämpfelemente entsteht. Ein weiterer Nachteil dieser Konstruktion ist, daß bei einem frontalen oder seitlichen Aufprall die Profilstähle leicht deformiert werden und sie infolge der Deformation die gewünschte energieabsorbierende Gleiteigenschaft nicht mehr aufweisen, sondern quasi fest miteinander verbunden sind. Weiter ist es ungünstig, daß die Verbindungseinrichtung nur auf zwei beabstandete Dämpfelemente und nicht auf direkt benachbarte bzw. auf mehr als zwei nebeneinanderliegende Dämpfelemente anwendbar ist.In the event of a side impact, this connection device has however, the disadvantage that the section steels immediately Stop pushed together and thus a very rigid Connection of the two damping elements is created. Another The disadvantage of this construction is that with a frontal or side impact the profile steels are slightly deformed and they become the desired ones due to the deformation no longer have energy-absorbing sliding properties, but are almost firmly connected. Is further it is unfavorable that the connecting device only on two spaced damping elements and not to directly adjacent or on more than two adjacent damping elements is applicable.

Die deutsche Offenlegungsschrift DE-A-2 816 487 offenbart einen Schutzplankenanpralldämpfer zur Verwendung von Hindernissen an Kraftfahrzeug-Verkehrswegen mit einer Vielzahl vor einer Betonabstützung angeordneten Dämpfelementen, die untereinander durch eine die Aufprallenergie absorbierende Vorrichtung verbunden sind, wobei die Vorrichtung ein quer zur Fahrtrichtung angeordnetes, mindestens zwei Dämpfelemente miteinander verbindendes Querseil umfaßt, das an den Dämpfelementen reibschlüssig festgelegt ist. Nachteilig an dem bekannten Anpralldämpfer ist jedoch die Tatsache, daß die über die Querseile miteinander verbundenen Dämpfelemente zueinander beabstandet sein müssen, um die Verbindung zu ermöglichen.The German patent application DE-A-2 816 487 discloses a crash barrier for the use of obstacles on motor vehicle traffic routes with a variety Damping elements arranged in front of a concrete support with each other by absorbing the impact energy Device are connected, the device being a transverse arranged to the direction of travel, at least two damping elements interconnecting cross rope, which to the Damping elements is fixed friction. Disadvantageous the known crash cushion is the fact that the damping elements connected to each other via the cross cables must be spaced from each other to make the connection to enable.

Demgemäß ist es Aufgabe der Erfindung, eine Vorrichtung zur Verbindung von Dämpfelementen der eingangs genannten Art derart weiterzubilden, daß zwei oder mehr direkt aneinanderliegende oder auch beabstandete Dämpfelemente durch die Verbindungseinrichtung des Schutzplankenanpralldämpfers so miteinander verbunden werden, daß die Aufprallenergie bei einem Frontalaufprall weitmöglichst absorbiert und die Energieabsorption bei einem Seitenaufprall nicht beeinträchtigt wird. Darüber hinaus soll es bei dem Anpralldämpfer auch möglich sein, unmittelbar benachbarte Dämpfelemente durch ein Querseil miteinander zu verbinden.Accordingly, it is an object of the invention to provide a device for Connection of damping elements of the type mentioned to further develop such that two or more are directly adjacent or spaced damping elements by the Connecting device of the crash barrier crash absorber are connected to each other so that the impact energy as much as possible in a frontal impact absorbed and energy absorption in the event of a side impact is not affected. In addition, it is said to the crash cushion may also be possible, immediately adjacent To connect damping elements to each other with a cross rope.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Schutzplankenanpralldämpfer eine Vorrichtung aufweist, welche ein quer zur Fahrtrichtung angeordnetes, mindestens zwei Dämpfelemente miteinander verbindendes Querseil umfaßt, das an den Dämpfelementen reib- und/oder formschlüssig festgelegt ist, wobei die Befestigung des Querseils jeweils innerhalb eines Dämpfelementes erfolgt.The object is achieved in that the crash barrier crash absorber has a device which has a transverse to the direction of travel, at least two damping elements connecting cross wire comprises, the friction elements on the damping and / or positive is fixed, the attachment of the cross rope each takes place within a damping element.

Der Vorteil der erfindungsgemäßen Ausbildung besteht darin, daß die miteinander zu verbindenden Dämpfelemente keinen Abstand voneinander aufweisen müssen, sondern auch direkt aneinander anliegen können. Ein weiterer Vorteil besteht darin, daß auch mehrere Dämpfelemente auf dem Querseil zwischen den beiden energieabsorbierenden Befestigungen des Querseils aufgereiht sein können. Die Dämpfelemente können dabei untereinander beabstandet und auch nicht beabstandet sein. Durch die erfindungsgemäße Verbindungsvorrichtung ergibt sich der weitere Vorteil, daß die Dämpfeigenschaften bei einem schrägen oder seitlichen Aufprall nicht durch eine auf Druck belastbare Verbindung beeinträchtigt werden.The advantage of the training according to the invention is that that the damping elements to be connected to each other none Must be at a distance from each other, but also directly can lie against each other. Another advantage is there in the fact that several damping elements on the cross rope between the two energy absorbing fastenings of the Can be lined up crosswise. The damping elements can spaced from each other and also not spaced be. Results from the connecting device according to the invention the further advantage is that the vapor properties in the event of an oblique or side impact, not through a pressure-resistant connection can be impaired.

Ein Vorteil der erfindungsgemäßen Ausbildung ergibt sich dadurch, daß die Befestigung des Querseils jeweils innerhalb eines Dämpfelements angeordnet ist. Durch diese Ausbildung ist es möglich, direkt aneinanderliegende Dämpfelemente miteinander zu verbinden.An advantage of the training according to the invention results yourself in that the attachment of the cross rope each is arranged within a damping element. Through this Training, it is possible to directly adjacent damping elements connect with each other.

Besonders günstig ist es, die Befestigung des Querseiles aus zwei zum anderen Ende des Querseils spitz zulaufende Klemmschienen auszubilden, zwischen denen das Klemmstück gehalten wird.It is particularly favorable to fasten the cross rope two clamping rails tapering to the other end of the cross rope train between which the clamping piece is held becomes.

Dabei ist es sehr günstig, die Klemmschienen als U-Profile auszubilden, die sich mit der Öffnung gegenüberliegen und Aussparungen zum Einsetzen des Klemmstücks aufweisen.It is very cheap to use the clamping rails as U-profiles to train who face each other with the opening and Have recesses for inserting the clamping piece.

Die Klemmschienen werden günstigerweise an ihren Stirnseiten über einen Flansch, welcher der Geometrie der Dämpfelemente angepaßt ist, mit den Dämpfelementen verbunden, wobei der innenseitige Flansch eine Durchgangsöffnung für das Querseil aufweist.The clamping rails are conveniently on their end faces via a flange, which corresponds to the geometry of the damping elements is adapted, connected to the damping elements, the inside flange an opening for the cross rope having.

Weiter ist es vorteilhaft, daß der außenseitige Flansch und der innenseitige Flansch mit dem Dämpfelement über Rundkopfschrauben verbunden werden. Speziell bei der Verschraubung des außenseitigen Flansches von außen ist es wichtig, daß der außenliegende Schraubenkopf keine scharfen Kanten aufweist, welche ein anprallendes Fahrzeug zusätzlich beschädigen oder eine anprallende Person verletzen könnten.It is also advantageous that the outside flange and the inside flange with the damping element via round-head screws get connected. Especially with the screw connection of the outside flange from the outside, it is important that the outside screw head has no sharp edges, which additionally damage an impacting vehicle or could injure an impacting person.

Weiter ist es vorteilhaft das Querseil zwischen den Klemmstücken durch Seilspannschrauben in den Klemmstücken zu fixieren. Die Ausbildung ist zum einen kostengünstig und zum anderen kann das Querseil durch Einschrauben der Seilspannschrauben in die Klemmstücke gespannt werden.It is also advantageous the cross rope between the Clamping pieces by means of rope tensioning screws in the clamping pieces fix. The training is inexpensive on the one hand and others can cross the rope by screwing in the rope tensioning screws be clamped into the clamping pieces.

Ebenso ist es vorteilhaft, im Querseil einen Seilspanner einzubauen. Dieser Seilspanner kann im Abstand zwischen zwei verbundenen Dämpfelementen bzw. bei mehreren verbundenen Dämpfelementen in einem mittleren Dämpfelement angeordnet sein.It is also advantageous to have a rope tensioner in the cross rope to install. This rope tensioner can be spaced between two connected damping elements or in the case of several connected Damping elements arranged in a central damping element be.

Weitere vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen definiert.Further advantageous developments of the invention are in the sub-claims defined.
