Description

Die Erfindung betrifft einen Schutzplanken-Anpralldämpfer der im Oberbegriff des Hauptanspruchs genannten Art.The invention relates to a crash barrier crash barrier of the type mentioned in the preamble of the main claim.

Derartige Schutzplanken-Anpralldämpfer finden vor Hindernissen, beispielsweise Brückenpfeiler, Straßengabelungen mit darin aufgestellten Masten, etc. Verwendung und haben im Falle eines Anpralls im wesentlichen zweierlei Funktionen. Zum einen dämpfen sie den Aufprall eines auffahrenden Kraftfahrzeugs und bremsen das Unfallfahrzeug dadurch ab, daß sich die in dem Anpralldämpfer in Reihe hintereinander angeordneten Dämpfelemente, beispielsweise aufrecht stehende Rohrabschnitte mit relativ großem Durchmesser, verformen und dadurch die Fahrzeugenergie aufzehren, zum anderen soll das Fahrzeug von dem Hindernis abgelenkt oder abgewiesen werden, damit es nach dem Passieren des Hindernisses auf dem Verkehrsweg oder am Rande des Verkehrswegs zum Stillstand kommt.Such crash barrier crash absorbers find obstacles, for example bridge pillars, road fork with masts, etc. installed in them essentially two functions in the event of an impact. On the one hand, they dampen the impact of a collision Motor vehicle and brake the accident vehicle by that in the crash cushion in a row arranged damping elements, for example upright Deform pipe sections with a relatively large diameter and thereby deplete vehicle energy, on the other the vehicle should be distracted from the obstacle or rejected to be there after passing the obstacle on the traffic route or on the edge of the traffic route to Standstill comes.

Ein bekannter Schutzplanken-Anpralldämpfer der genannten Gattung weist als Abstützbock eine U-förmige Betonkonstruktion auf, bei der die Basis des U gegen die Fahrtrichtung zeigt und als Anlage für die Rohrabschnitte dient. Gleichzeitig dient dieses Betonfundament als Widerlager für die bei einem solchen Anpralldämpferaufbau verwendeten Spannseile.A known crash barrier crash barrier of the above Genus has a U-shaped concrete structure as a support frame on where the base of the U is against the direction of travel shows and serves as a system for the pipe sections. At the same time this concrete foundation serves as an abutment for the tension cables used in such an impact damper construction.

Wenn nun ein Fahrzeug schräg seitlich an dieses Anpralldämpfersystem heranfährt, kann es infolge der hohen Energie zu einem Verformen der seitlichen Leitplanken und zu einem Zusammendrücken der dahinter stehenden Rohrabschnitte kommen. Gleichzeitig wird das Fahrzeug an der Schutzplanke abgelenkt und bewegt sich auf den Abstützbock zu. Hatte das Fahrzeug eine hohe Aufprallgeschwindigkeit, so wird die Bewegung durch einen heftigen Anprall an dem nicht nachgebenden Abstützblock abgestoppt. Dies ist unerwünscht, da in jedem Fall ein ungedämpfter Anprall zu vermeiden ist, um Schaden an Menschenleben und Sachgütern zu verhindern.Now if a vehicle is slanted to the side of this crash cushion system approaching, it can be due to the high energy to deform the side guardrails and to one Compress the pipe sections behind it. At the same time, the vehicle is deflected on the crash barrier and moves towards the jack. Had this Vehicle a high impact speed, so the movement by a violent impact on the non-yielding Support block stopped. This is undesirable because in an undamped impact is to be avoided in every case To prevent damage to human life and property.

Die U.S. Patentschrift 4,815,565 offenbart einen Schutzplanken-Anpralldämpfer vor Hindernissen an Kraftfahrzeug-Verkehrswegen mit einem Kopfteil und einem Abstützbock sowie zwischen beiden in Reihe hintereinander angeordneten Dämpfelementen und daran seitliche, dem Verkehrsweg zugewandte Abweiseinrichtungen. Auch bei diesem bekannten Schutzplanken-Anpralldämpfer ist die Dämpfungswirkung bei einem schrägen Aufprall eines Fahrzeugs unbefriedigend.The U.S. Patent 4,815,565 discloses a crash barrier crash cushion from obstacles on motor vehicle traffic routes with a headboard and a support frame as well between the two arranged in a row Damping elements and on the side facing the traffic route Deflectors. Even with this well-known The crash barrier is the damping effect an oblique impact of a vehicle is unsatisfactory.

Weiterhin ist aus der U.S. Patentschrift 3,602,151 ein Anpralldämpfer für Züge bekannt, der einen eine im wesentlichen senkrecht stehende Rampenform mit sich gegen die Fahrtrichtung hin verjüngendem Aufbau aufweisenden Abstützbock enthält. Dieser bekannte Anpralldämpfer ist jedoch nur zur Dämpfung des Anpralls von schienengebundenen Fahrzeugen vorgesehen. Furthermore, from U.S. Patent 3,602,151 an impact damper known for trains, one essentially one vertical ramp shape with itself against the Support frame with tapering body contains. However, this known crash cushion is only to dampen the impact of rail-bound vehicles intended.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Schutzplanken-Anpralldämpfer der genannten Art so zu verbessern, daß die Aufprall- und Weiterleitungsfunktion auch im Bereich des Abstützbocks weitgehend erhalten bleiben.The invention is therefore based on the object To improve crash barrier crash dampers of the type mentioned so that the impact and forwarding function also in Area of the jack is largely preserved.

Die Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des unabhängigen Anspruchs angegebenen Merkmale gelöst.The object is achieved by the in the characterizing Part of the independent claim specified features solved.

Mit dieser Konstruktion ist es möglich, daß ein aufprallendes Fahrzeug im Bereich des Abstützblocks relativ weich aufgefangen wird. Infolge der Bewegbarkeit der Abstützeinrichtung kommt es auch zu einem Nachgeben gegenüber einem aufprallenden Kraftfahrzeug, ohne daß diesem ein besonders hoher Widerstand entgegengesetzt wird. Dabei stützt die Abstützeinrichtung zunächst das letzte Rohrsegment und wirkt dann selber bei Anprall eines Fahrzeugs als ein Dämpfelement. With this construction it is possible that an impacting Vehicle caught relatively softly in the area of the support block becomes. As a result of the mobility of the support device there is also a yielding to an impacting one Motor vehicle without this being a particularly high one Resistance is opposed. The support device supports this first the last pipe segment and acts then even when a vehicle collides as one Damping element.

Als ein günstiger Aufbau hat sich für die Abstützeinrichtung eine U-Form herausgestellt, wobei die Basis des U als Vorderwand quer zur Fahrtrichtung angeordnet ist und die freien Schenkel des U als Seitenwände jeweils an einem seitlichen Befestigungsabschnitt des Abstützbocks verschiebbar befestigt sind.Has proven to be a favorable structure for the support device highlighted a U shape, with the base of the U as the front wall is arranged transversely to the direction of travel and the free Legs of the U as side walls each on a side Fastening section of the support bracket slidably attached are.

Günstig ist dabei, daß die Vorderwand an einer am verjüngten Ende des Abstützbocks angeordneten Stirnwand verschiebbar befestigt ist. Die Verschiebbarkeit der Abstützeinrichtung am Ort der Befestigung wird vorteilhafterweise mittels einer Langlochverschraubung hergestellt, wobei die Langlöcher günstigerweise an der Abstützeinrichtung ausgebildet sind. Dadurch, daß die Befestigungsbolzen mit einem vorbestimmten Moment angezogen sind, ist eine Verschiebung einer bestimmten Krafteinwirkung gewährleistet. Diese Verschiebung endet dann, wenn das Ende des Langlochs am Befestigungsbolzen angekommen ist. In einem solchen Fall verformt sich die U-förmige Abstützeinrichtung und nimmt auf diese Weise die Bewegungsenergie des Kraftfahrzeugs auf.It is favorable that the front wall on a tapered End of the support bracket arranged end wall slidably is attached. The displaceability of the support device at the place of attachment is advantageously by means of a Elongated screw connection made, the elongated holes favorably are formed on the support device. Thereby, that the fastening bolts with a predetermined Moment is a shift of a certain one Force guaranteed. This shift ends when the end of the elongated hole has reached the fastening bolt is. In such a case, the U-shape deforms Support device and in this way takes the kinetic energy of the motor vehicle.

Der Abstützblock kann jede geeignete Keilform aufweisen, günstig hat sich jedoch eine in Draufsicht V-förmige Gestalt erwiesen, bei der die Stirnwand, die Ablenkwände und die seitlichen Befestigungswandabschnitte für die Schenkel der U-förmigen Abstützeinrichtung im wesentlichen ebene Außenflächen aufweisen.The support block can have any suitable wedge shape, However, a V-shaped shape in plan view is advantageous proven in which the bulkhead, the baffles and the lateral fastening wall sections for the legs of the U-shaped support device essentially flat outer surfaces exhibit.

Um eine Verformung der Abstützeinrichtung zu erleichtern ist die Vorderwand im Befestigungsbereich plateauähnlich zur Stirnwand vorspringend ausgebildet, wobei der Übergang aus der Vorderwandebene zum Plateau ausgerundet ist. Hierdurch wirkt die ausgerundete Kante wie ein Gelenk, so daß die Verformung nach einem gewissen Anfangswiderstand relativ leicht vonstatten geht. To facilitate deformation of the support device the front wall in the fastening area is similar to a plateau Protruding end wall, the transition from the front wall level is rounded to the plateau. Hereby the rounded edge acts like a hinge, causing the deformation relatively easy after a certain initial resistance takes place.

Bei einer günstigen Weiterbildung kann vorgesehen sein, daß die Abstützeinrichtung im Befestigungsbereich geteilt ist, wobei jedes Teil einen Befestigungsbereich mit Langlöchern aufweist und die Befestigungsbereiche sich überlappend an der Stirnwand festgelegt sind. Auf diese Weise kann verhindert werden, daß bei einem relativ leichten Anprall auf den Abstützbock die nicht am Unfall beteiligte gegenüberliegende Wand der Abstützeinrichtung beschädigt wird.In the case of a favorable further development, it can be provided that the support device is divided in the fastening area, each part has an attachment area with elongated holes and the attachment areas overlap the end wall are fixed. This can prevent it be that with a relatively light impact on the Outrigger the opposite one not involved in the accident Wall of the support device is damaged.

In den übrigen Unteransprüchen sind weitere vorteilhafte Ausgestaltungen der Erfindung angegeben.In the remaining subclaims there are further advantageous ones Embodiments of the invention specified.

Im folgenden wird die Erfindung anhand der in der Zeichnung dargestellten Ausführungsbeispiele näher erläutert. Es zeigen:

In Fig. 1 ist ein Schutzplanken-Anpralldämpfer 1 in Ansicht von oben dargestellt. Der Schutzplanken-Anpralldämpfer 1 weist ein Kopfteil 2, Dämpfelemente 3 und einen Abstützblock 4 auf. Die Dämpfelemente 3 sind paarweise in Reihe hinter dem Kopfteil 2 angeordnet, wobei als ein bevorzugtes Dämpfelement senkrecht stehende Rohrabschnitte verwendet werden. Diese Rohrabschnitte können mit geeigneten Materialien gefüllt sein.In Fig. 1, a crash barrier crash damper 1 is in view shown from above. The crash barrier 1 has a head part 2, damping elements 3 and a support block 4 on. The damping elements 3 are in pairs in a row behind the head part 2 arranged, being a preferred Damping element vertical pipe sections used become. These pipe sections can be made with suitable materials be filled.

Die Reihe der Dämpfelemente stützt sich an dem Abstützbock 4 ab. Der Abstützbock 4 weist eine stehende Rampenform auf, wobei im dargestellten Ausführungsbeispiel der Abstützbock eine V-förmige Gestalt besitzt. Das spitze Ende des V-förmigen Abstützbocks weist gegen die Fahrtrichtung. An dem Abstützbock 4 ist eine Abstützeinrichtung 8 verschiebbar befestigt. Die Abstützeinrichtung 8 weist im wesentlichen einen U-förmigen Aufbau 9 auf, wobei die Basis des U als Vorderwand 11 quer zur Fahrtrichtung angeordnet ist und unmittelbar gegen die paarweise aufgereihten Dämpfelemente 3 anstößt. Die freien Schenkel der U-förmigen Abstützeinrichtung 8 sind als Seitenwände 10 ausgebildet, die jeweils an seitlichen Befestigungswandabschnitten 7 des Abstützbocks 4 verschiebbar befestigt sind, sie können jedoch auch unbeweglich angeschraubt sein. Die Befestigungswandabschnitte 7 sind kurze, in Fahrtrichtung weisende Fortsetzungen der V-förmigen Schenkel des Abstützbocks 4.The row of damping elements is supported on the support frame 4 from. The support frame 4 has a standing ramp shape, in the illustrated embodiment, the support frame has a V-shaped shape. The pointed end of the V-shaped Outrigger points against the direction of travel. On the support frame 4, a support device 8 is slidably attached. The support device 8 essentially has one U-shaped structure 9, with the base of the U as a front wall 11 is arranged transversely to the direction of travel and immediately abuts the damping elements 3 lined up in pairs. The free legs of the U-shaped support device 8 are designed as side walls 10, each on the side Fastening wall sections 7 of the support frame 4 are displaceable are attached, but they can also be immobile be screwed on. The mounting wall sections 7 are short continuations of the V-shaped in the direction of travel Leg of the support frame 4.

Auch die Vorderwand 11 ist an einer am verjüngten Ende des Abstützbocks ausgebildeten Stirnwand 5 verschiebbar befestigt. Die Verschiebbarkeit der Abstützeinrichtung 8 gegenüber dem Abstützbock wird durch eine Langloch-Schraubenbolzenbefestigung 13,16 erreicht. Die Befestigungsbolzen 16 werden dabei mit einem vorbestimmten Anzugsmoment angezogen, so daß sie bis zu einem vorbestimmten Aufprall unbeweglich bleiben. Bei einem diese Grenze übersteigenden Aufprall jedoch eine Verschiebung der Vorderwand bzw. der Seitenwand bis zum Erreichen des Langlochendes ermöglichen. Nachdem eine solche Verschiebung stattgefunden hat, kann es bei einem starken Aufprall zu einer Verformung der Seitenwände bzw. Vorderwand kommen. Die Befestigung der Seitenwände 10 der Abstützeinrichtung an dem seitlichen Befestigungswandabschnitt 7 des Abstützbocks kann ebenfalls mittels einer Langlochbefestigung durchgeführt werden.The front wall 11 is at one at the tapered end of the Support bracket trained end wall 5 slidably attached. The displaceability of the support device 8 compared the support stand is attached by an elongated bolt bolt 13.16 reached. The fastening bolts 16 are tightened with a predetermined torque, so that it is immobile until a predetermined impact stay. However, if the impact exceeds this limit a displacement of the front wall or the side wall allow until reaching the slot end. After this such a shift may have occurred in one strong impact to a deformation of the side walls or front wall. The attachment of the side walls 10 the support device on the side fastening wall section 7 of the support frame can also be carried out by means of an elongated hole fastening.

Die geometrische Form der senkrecht stehenden Rampe kann anstatt wie bei der dargestellten Ausführungsform, bei der sämtliche Wände ebene Außenflächen aufweisen, auch von gerundeter Gestalt sein.The geometric shape of the vertical ramp can take place instead as in the illustrated embodiment in which all walls have flat outer surfaces, including rounded ones Be in shape.

In Fig. 2 ist eine vergrößerte Darstellung des in Fig. 1 dargestellten Details II wiedergegeben. Die Vorderwand 11 der Abstützeinrichtung 8 ist im Befestigungsbereich 12 plateauähnlich zum Stirnwand 5 des Abstützblocks 4 vorgezogen und bildet gegenüber der Vorderwandebene 11' quasi ein Plateau 12'. Der Übergang aus der Vorderwandebene 11' zu dem Plateau 12' ist ausgerundet, wodurch ein günstiges Verformungsverhalten erreicht wird.FIG. 2 is an enlarged illustration of that in FIG. 1 shown details II reproduced. The front wall 11 the support device 8 is plateau-like in the fastening area 12 advanced to the end wall 5 of the support block 4 and forms a plateau with respect to the front wall plane 11 ' 12 '. The transition from the front wall level 11 'to the Plateau 12 'is rounded, which results in a favorable deformation behavior is achieved.

Bei dem in Fig. 2 dargestellten Ausführungsbeispiel ist die Abstützeinrichtung 8 im Befestigungsbereich 12 geteilt, wobei jedes Teil einen Befestigungsbereich 12 mit Langlöchern 13 aufweist und die Befestigungsbereiche 12 einander überlappend an der Stirnwand 5 festgelegt sind.In the embodiment shown in Fig. 2 is the Support device 8 divided in the fastening area 12, wherein each part has a fastening area 12 with elongated holes 13 and the fastening areas 12 each other are fixed overlapping on the end wall 5.

Auch die Kante zwischen der Vorderwand 11 und der Seitenwand 10 der Abstützeinrichtung 8 ist, wie in Fig. 1 zu erkennen, ebenfalls ausgerundet.Also the edge between the front wall 11 and the side wall 10 of the support device 8, as can be seen in FIG. 1, also rounded out.

Es wird nun auf die Fig. 3 in Verbindung mit Fig. 2 Bezug genommen. Fig. 3 zeigt eine Vorderansicht auf die Vorderwand 11 der an dem Abstützblock 4 angeordneten Abstützeinrichtung 8. Seitlich der Seitenwände 12 sind die Schutzplanken 15 gestrichelt angedeutet. In der dargestellten Ausführungsform sind zwei übereinander angeordnete Langlöcher 13 mit je einem Befestigungsbolzen 16 im Befestigungsbereich 12 wiedergegeben.3 in conjunction with FIG. 2 taken. Fig. 3 shows a front view of the front wall 11 of the support device arranged on the support block 4 8. The side rails 12 are dashed 15 indicated. In the illustrated embodiment are two elongated holes 13 arranged one above the other, each with one Fastening bolt 16 shown in the fastening area 12.

Des weiteren sind Durchbrüche 14 für die Spannseile 20 vorgesehen, die, vergl. Fig. 2, durch weitere Durchbrüche 14' in der Ablenkwand 6 hindurchführen und je in einem Widerlager 19 (vergl. Fig. 4, Fig. 1) des Abstützblocks befestigt sind.Furthermore, openings 14 are provided for the tensioning cables 20, which, see FIG. 2, through further openings 14 ' pass through the baffle 6 and each in an abutment 19 (see Fig. 4, Fig. 1) of the support block attached are.

Die Widerlager 19 sind als Halteblock mit quer zur Zugrichtung der Spannseile angeordneter Spannplatte 23 ausgebildet. Die Spannseile sind in üblicher Weise an der Spannplatte nachspannbar. Zur Befestigung es Abstützblocks 4 ist eine Bodenplatte 17 an dem Abstützblock angeschweißt. Sie kann in geeigneter Weise mittels Schraubenbolzen an einem Fundament aufgeschraubt werden.The abutments 19 are a holding block with transverse to the direction of pull the tensioning cables arranged tensioning plate 23 is formed. The tensioning ropes are in the usual way on the tensioning plate retensionable. To attach it support block 4 is one Base plate 17 welded to the support block. You can in suitably using bolts on a foundation be screwed on.

Die Erfindung ist nicht auf die dargestellten Ausführungsbeispiele und geometrischen Formen beschränkt.The invention is not based on the illustrated embodiments and geometric shapes.

So kann beispielsweise die Form des Abstützbocks eine gerundete V-Form aufweisen oder es kann die Ablenkwand 6 waschbrettähnlich gewellt oder mit Stufen versehen sein, wodurch ein zusätzlicher Abbremseffekt erzielt wird. Auch ist es möglich, daß der Abstützbock mit konisch nach unten sich verjüngenden Ablenkwänden ausgerüstet ist, wobei um eine Verkeilung zu verhindern, diese Verjüngung lediglich bis zu einer Höhe von cirka einem Raddurchmesser eines Pkw heruntergezogen wird, wobei der untere Bereich dann wieder senkrecht stehend verläuft. For example, the shape of the support frame can be rounded V-shaped or the baffle 6 can be like a washboard be corrugated or provided with steps, whereby an additional braking effect is achieved. It is too possible that the jack with conical down tapered baffles is equipped with a To prevent wedging, this taper only up to about a wheel diameter of a car is pulled down, the lower area then again runs vertically.

Die Außenfläche der Ablenkwand 6 kann neben der oben erwähnten Abwandlung auch profiliert, mit Sicken oder Nocken versehen sein.The outer surface of the baffle 6 may be adjacent to that mentioned above Modification also profiled, with beads or cams be.

Auch die Vorderwand der Abstützung 8 kann, abweichend von der wiedergegebenen, im wesentlichen ebenen Gestalt, an jeder Seite einen im wesentlichen S-förmigen Aufbau aufweisen, wobei die Ausrundung des S dem Durchmesser des unmittelbar benachbarten Dämpfelements angepaßt sein kann. Hierdurch erfährt ein Fahrzeug bereits im Bereich vor dem Abstützbock eine etwas stärkere Abbremsung, so daß bei einer hohen Anfangsaufprallwucht vor Erreichen des starren Abstützbocks zusätzliche Bewegungsenergie aufgezehrt werden kann.The front wall of the support 8 can, deviating from the depicted, essentially flat shape, on each Side have an essentially S-shaped construction, where the fillet of the S is the diameter of the immediate adjacent damping element can be adapted. Learns about this a vehicle is already in the area in front of the jack a somewhat stronger braking, so that with a high initial impact force before reaching the rigid support frame additional kinetic energy can be consumed.

Die Abstützeinrichtung 8 kann jedoch statt einer U-förmigen Ausbildung eine im wesentlichen in Draufsicht T-förmige Gestalt aufweisen, wobei der Querbalken des T nach oben gerundet ist und in dieser Rundung ein Dämpfelement aufnimmt. Der Schenkel des T läuft auf die schräge Rampe zu und ist in geeigneter Weise an der Ablenkwand verschraubt.The support device 8 can, however, instead of a U-shaped Forming a substantially T-shaped shape in plan view have, with the crossbar of the T up is rounded and in this rounding a damping element records. The leg of the T runs towards the sloping ramp and is screwed to the baffle in a suitable manner.

Die Abstützeinrichtung 8 kann in den oben beschriebenen Ausführungsbeispielen von einer Stahlplattenkonstruktion gebildet sein, wobei in U-förmiger Ausführung diese Abstützeinrichtung aus einem Stück gebogen, jedoch auch aus einzelnen Platten zusammengesetzt sein kann.The support device 8 can be described in the above Embodiments of a steel plate construction be formed, these in a U-shaped design Support device bent from one piece, but also from individual plates can be composed.
