Nachteilig an den bekannten Systemen ist jedoch, dass der Einbau und Anschluss durch aufwendiges Einmessen an der Einbaustelle und die Zuordnung von vielen Parametern gekennzeichnet ist. Zusätzlich ist nachteilig, dass die Leitelemente bei einem Anprall im wesentlichen willkürlich um einen einzigen Drehpunkt umgebogen werden.A disadvantage of the known systems, however, is that the installation and connection is characterized by costly calibration at the installation site and the assignment of many parameters. In addition, it is disadvantageous that the guide elements are substantially arbitrarily bent around a single pivot point in an impact.
Der Erfindung liegt die Aufgabe zugrunde, eine Schutzeinrichtung für den Anfangs- bzw. Endbereich an bestehenden Fahrzeugrückhaltesystemen bereitzustellen, die leicht aufstellbar ist.The invention has for its object to provide a protective device for the beginning or end of existing vehicle restraint systems, which is easy to install.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Durch die erfindungsgemäße Merkmalskombination ist es möglich, dass durch eine gegenüber dem Stand der Technik kompakte Anfangs- und Endkonstruktion ein nach der Norm festgelegtes Anprallverhalten erreicht wird und frontal anprallende Fahrzeuge sicher auf die dem Verkehr abgewandte Seite geleitet werden. Ein Aufgleiten, Aufsitzen oder Unterfahren eines anprallenden Fahrzeugs wird sicher verhindert. Durch die erfindungsgemäße Anordnung von mindestens einem Abstützpfosten an der vorderen Anprallfläche und mindestens zwei Abstützpfosten an der hinteren Anprallfläche, wobei durch diese Abstützpfosten ein im wesentlichen polygone Fläche mit drei Ecken aufgespannt wird, kann der Einbau der Anfangs- und Endkonstruktion ohne aufwendiges Einmessen an der Einbaustelle, ohne Zuordnen von verschiedenen Parametern, ohne eine Hilfskonstruktion und ohne zusätzliche Bauteile erfolgen.This object is solved by the characterizing features of
Dabei ist es vorteilhaft, dass mindestens einer der Abstützpfosten mindestens eine Sollbruchstelle aufweist, wobei die mindestens eine Sollbruchstelle im Bodenbereich des Verkehrswegs angeordnet ist. Durch die Sollbruchstelle ist es bei einem Anprall möglich, dass die jeweiligen Pfosten mit der Anfangs- und Endkonstruktion verschoben werden und somit keine zusätzliche Gefährdung für das anprallende Fahrzeug darstellen. Die Art und Ausbildung der Sollbruchstelle kann gezielt die Biege- und Drehbewegung bzw. die Verformung beeinflussen.It is advantageous that at least one of the Abstützpfosten has at least one predetermined breaking point, wherein the at least one predetermined breaking point is arranged in the bottom region of the traffic route. Due to the predetermined breaking point, it is possible in the event of an impact that the respective posts are displaced with the start and end construction and thus do not represent any additional danger to the impacting vehicle. The type and design of the predetermined breaking point can specifically influence the bending and rotational movement or the deformation.
Vorteilhafterweise können die Abstützpfosten einen leicht lösbaren Schiebe-Klemmsitz aufweisen, durch den das Anprallelement einfach befestigbar und wieder lösbar ist. Über mindestens einen stabilen Tragepfosten kann das Anprallelement unmittelbar mit dem Rückhaltebereich verbunden sein und somit einen stufenlosen Übergang von dem Anprallelement auf den Rückhaltebereich sicherstellen.Advantageously, the Abstützpfosten can have an easily releasable sliding-clamping seat, through which the impact element is easy to attach and detach again. Via at least one stable support post, the impact element can be directly connected to the retention area and thus ensure a stepless transition from the impact element to the retention area.
Der Rückhaltebereich selbst ist vorzugsweise von einem, zwei, drei oder vier Tragepfosten getragen, durch den/die die Anfangs- und Endkonstruktion mit dem Boden verankert ist/sind. In einer bevorzugten Ausführung sind die Tragepfosten 1,75 Meter lang und einen Meter tief in den Boden gerammt. Auf diese Weise ist eine widerstandsfähige Verankerung des Rückhaltebereichs gegenüber anprallenden Fahrzeugen sichergestellt.The retention area itself is preferably carried by one, two, three or four support posts through which the initial and final construction is anchored to the floor. In a preferred embodiment, the support posts are 1.75 meters long and one meter deep rammed into the ground. In this way, a resilient anchoring of the retention area is ensured against impacting vehicles.
In einer alternativen Ausführungsform können im rückwärtigen Bereich des Rückhaltebereichs ersatzweise oder zusätzliche Dämpfelemente angeordnet sein, durch die der Rückhaltebereich zusätzlich zu den Tragepfosten getragen sein kann. Hierdurch ist eine zusätzliche Dämpfung des Anpralls im Rückhaltebereich ermöglicht.In an alternative embodiment, replacement or additional damping elements can be arranged in the rear region of the retention region, by means of which the retention region can be supported in addition to the support posts. This allows additional damping of the impact in the retention area.
In einer bevorzugten Ausführungsform ist das Verhältnis zwischen der Länge und der Tiefe des Anprallelements im wesentlichen 2:1, wobei besonders bevorzugt eine Länge von zwei Metern und eine Tiefe von einem Meter sind. Das Längenverhältnis des Anprallelements zu dem Rückhaltebereich kann vorteilhafterweise 1:2 sein, wobei insgesamt eine besonders günstige kompakte bauform der Anfangs- und Endkonstruktion erzielt werden kann.In a preferred embodiment, the ratio between the length and the depth of the impact element is substantially 2: 1, more preferably a length of two meters and a depth of one meter. The aspect ratio of the impact element to the retention area can advantageously be 1: 2, with a total of a particularly favorable compact design of the initial and final construction can be achieved.
Ein vorteilhaftes Merkmal der Erfindung ist, dass anprallende Fahrzeuge durch das Anprallelement verzöger- und umlenkbar und durch den Rückhaltebereich zurückhaltbar sind. Durch diese Ausbildung ist zu realisieren, dass gegen das Anprallelement prallende Fahrzeuge hinter die Anfangs- und Endkonstruktion und gegen den Rückhaltebereich anprallende Fahrzeuge zurück auf die Fahrbahn leitbar sind. Möglicherweise hinter dem Rückhaltebereich angeordnete Objekte können somit geschützt werden.An advantageous feature of the invention is that impacting vehicles can be delayed and deflected by the impact element and retained by the retention area are. With this design, it is possible to realize that vehicles bouncing against the impact element can be guided back onto the roadway behind the start and end construction and against the restraint area. Possibly located behind the retention area objects can thus be protected.
Auch ist es günstig, dass das Anprallelement bei einem Anprall vollständig deformierbar und zumindest um den Tragepfosten des Anprallelements schwenk- und biegbar ist, wobei mindestens ein Tragepfosten den Dreh- und Angelpunkt bildet und den Schwenkbereich des Anprallelements bestimmt. Durch die mögliche Deformation bzw. Biegung kann ein Großteil der kinetischen Energie des anprallenden Fahrzeugs umgewandelt und somit die Verletzungswahrscheinlichkeit verringert werden. Die Anordnung des Tragepfostens als Drehpunkt kann individuell nach den tatsächlichen Gegebenheiten variiert werden, z.B. je weiter vorne der Tragepfosten angeordnet ist, desto kürzer ist der Hebelarm zum Verbiegen der Anfangs- und Endkonstruktion und entsprechend größer der Widerstand zum Biegen bzw. Verformen dieser.It is also favorable that the impact element in a collision is completely deformable and at least pivotable about the support post of the impact element and bendable, wherein at least one support post forms the fulcrum and determines the pivoting range of the impact element. By the possible deformation or bending a large part of the kinetic energy of the impacting vehicle can be converted and thus the probability of injury can be reduced. The arrangement of the support post as a fulcrum can be varied individually according to the actual circumstances, e.g. the further the front of the support post is arranged, the shorter is the lever arm for bending the initial and final construction and correspondingly greater resistance to bending or deforming this.
Auch ist vorteilhaft, dass das Anprallelement sich im wesentlichem in einem Kreisbogen in Richtung der dem Verkehr abgewandten Seite erstreckt und dabei in der Draufsicht eine im wesentlichen geschlossene Schleifenform aufweist. Über seinen Verlauf kann das Anprallelement ferner gegenüber der Fahrtrichtung abschnittsweise unterschiedliche Winkel aufweisen. Durch diesen einzigartigen Aufbau ist eine individuelle Anpassung bezüglich des zu realisierenden Anprallwiderstands der Anfangs- und Endkonstruktion ermöglicht, wobei sich der Widerstand bei größeren Winkeln verringert und die Anfangs- und Endkonstruktion leichter umbiegen lässt.It is also advantageous that the impact element extends substantially in a circular arc in the direction of the side facing away from the traffic and thereby has a substantially closed loop shape in plan view. Over its course, the impact element can also have sections opposite the direction of travel different angles. This unique design allows for customization of the impact resistance of the initial and final design to be realized, reducing drag at larger angles and making it easier to bend the initial and final designs.
Es ist günstig, dass das Anprallelement eine vordere und eine hintere Anprallfläche aufweist, die jeweils durch eine Holmanordnung gebildet sind, wobei die Holmanordnung aus vorzugsweise zwei übereinander angeordneten Holmen besteht. Vorteilhaft dabei ist, dass das Anprallelement im vorderen Bereich mindestens einen Kopfbogen und im hinteren Bereich mindestens einen Abflussbügel aufweist. Durch diese spezielle Ausgestaltung ist eine Anpassung der Deformierbarkeit des Anprallelements in den verschiedenen Anschnitten in Längsrichtung und ein zusätzlicher Schutz für Kraftradfahrer möglich.It is favorable that the impact element has a front and a rear impact surface, which are each formed by a spar assembly, wherein the spar assembly consists of preferably two superposed spars. It is advantageous that the impact element has at least one head bow in the front region and at least one drainage bow in the rear region. This special embodiment makes it possible to adapt the deformability of the impact element in the various sections in the longitudinal direction and provide additional protection for motorcyclists.
Ebenfalls günstig ist, dass im Inneren des Anprallelements im wesentlichen rohrförmige und durch Längsstreben miteinander verbundene Dämpfungselemente angeordnet sind, die zur Energieabsorption des anprallenden Fahrzeugs beitragen. Mit den Längsstreben kann ein Kraftfluss von einem Dämpfungselement auf das jeweils nachfolgende Dämpfungselement erfolgen.It is also favorable that arranged in the interior of the impact element substantially tubular and interconnected by longitudinal struts damping elements are that contribute to the energy absorption of the impacting vehicle. With the longitudinal struts, a flow of force from one damping element to the respective subsequent damping element can take place.
In einer bevorzugten Ausführung kann der Rückhaltebereich durch zwei Holme gebildet sein, die an den Tragepfosten befestigt sind, wobei der untere Holm im Bereich des in Längsrichtung letzten Tragepfostens in einem Bogen um den Tragepfosten herumgeführt und rückseitig daran befestigt ist. Durch den Bogen und die rückseitige Befestigung wird ein scharfkantiges Hervorstehen von Metallteilen im Falle eines Anpralls insbesondere bei dem Anprall eines Zweiradfahrers sicher verhindert.In a preferred embodiment, the retaining portion may be formed by two spars which are attached to the support post, wherein the lower spar in the region of the last longitudinal support post in an arc around the support post led around and back attached thereto. The bow and the rear attachment a sharp-edged protrusion of metal parts in the event of an impact, especially in the impact of a two-wheeled driver safely prevented.
Auch ist für die Krafteinleitung in die Anfangs- und Endkonstruktion vorteilhaft, dass in Längsrichtung der Abstand der Abschnittspfosten geringer ist als der Abstand der Tragepfosten. Es ist auch günstig, dass die im rückwärtigen Bereich des Rückhaltebereichs angeordneten Dämpfelemente eine unter Last verformbare und/oder verschiebliche und/oder zerstörbare Anprallmasse sind, an der die Holme des Rückhaltebereichs befestigbar sind. Die Dämpfelemente können wesentlich zur Umwandlung der kinetischen Energie des Anprallfahrzeugs beitragen. Als bevorzugte Ausführungen können die Dämpfelemente die Bauart einer Gabione oder einer unter Last zerstörbaren Betonstruktur, z.B. Bröselbeton, aufweisen.It is also advantageous for the introduction of force into the initial and final construction that the distance of the section posts in the longitudinal direction is less than the distance of the support posts. It is also favorable that the damping elements arranged in the rear region of the retaining region are a compressible mass deformable under load and / or displaceable and / or destructible, on which the bars of the retaining region can be fastened. The damping elements can significantly contribute to the conversion of the kinetic energy of the impact vehicle. As preferred embodiments, the damping elements may be of the gabion type or load-destructible concrete structure, e.g. Bröselbeton, exhibit.
Zusätzlich kann die Anfangs- und Endkonstruktion einen zusätzlichen Anschlussbereich aufweisen, der mit dem Fahrzeugrückhaltesystem verbunden ist. Vorteilhafterweise erstreckt sich entlang des Anschlussbereichs mindestens ein Holm, der durch Pfosten getragen ist, wobei zwischen dem Pfosten und dem mindestens einen Holm ein Verformungselement mit Dämpfungseigenschaften angeordnet ist. Im rückwärtigen Bereich kann der Anschlussbereich eine Abspannung aufweisen. Der Anschlussbereich dient optional zum Anschluss des Rückhaltebereichs an ein bestehendes Fahrzeugrückhaltesystem.Additionally, the beginning and ending construction may include an additional connection area connected to the vehicle restraint system. Advantageously, extends along the connection area at least one spar, which is supported by posts, wherein between the post and the at least one spar a deformation element is arranged with damping properties. In the rear region, the connection region can have a bracing. The connection area is optionally used to connect the retention area to an existing vehicle restraint system.
Des weiteren ist es vorteilhaft, dass die Anfangs- und Endkonstruktion als Abschlussverankerung einer bestehenden Schutzeinrichtung verwendbar ist, wobei sie auch eine Abschlussausbildung der Schutzeinrichtung oder ein Objektschutz für einzeln stehende Hindernisse darstellen kann. Besonders von Vorteil ist dabei, dass durch die Anfangs-und Endkonstruktion ein stufenloser bzw. unmittelbarer und kraftschlüssiger Übergang zu der bestehenden Schutzeinrichtung an Straßen bzw. Verkehrswegen realisierbar ist.Furthermore, it is advantageous that the beginning and end construction can be used as a final anchorage of an existing protection device, wherein it can also represent a final training of the protection device or an object protection for isolated obstacles. It is particularly advantageous that a stepless or direct and non-positive transition to the existing protective device on roads or traffic routes can be realized by the initial and final construction.
Auch günstig ist, dass die Anfangs- und Endkonstruktion auch zum Anschluss an eine einfache Distanzschutzplanke, an eine einfache Schutzplanke, an eine Super-Rail oder eine Betonschutzwand verwendet werden kann.It is also favorable that the initial and final construction can also be used for connection to a simple distance protection plank, to a simple protective barrier, to a super-rail or concrete protection wall.

Die
Die Anfangs- und Endkonstruktion der Erfindung ist insbesondere als eine Abschlussverankerung eines bestehenden Fahrzeugrückhaltesystems verwendbar. Durch das Umleiten des Fahrzeuges auf die dem Verkehr abgewandte Seite ist neben der Abschlussausbildung auch eine Verwendung als Objektschutz möglich, wenn das zu schützende Objekt vorzugsweise hinter dem Rückhaltebereich angeordnet ist. Die Anfangs- und Endkonstruktion zeichnet sich insbesondere dadurch aus, dass mit ihr ein stufenloser, unmittelbarer und kraftschlüssiger Übergang zu bestehenden Fahrzeugrückhaltesystemen an Straßen oder Verkehrswegen realisierbar ist.The initial and final construction of the invention is particularly useful as a termination anchor of an existing vehicle restraint system. By redirecting the vehicle to the side facing away from traffic, in addition to the final training, use as object protection is also possible if the object to be protected is preferably arranged behind the retention area. The initial and final construction is characterized in particular by the fact that with it a stepless, direct and non-positive transition to existing vehicle restraint systems on roads or roads can be realized.
Es wird ausdrücklich darauf hingewiesen, dass alle verschiedenen Merkmalselemente der einzelnen Ausführungsbeispiele beliebig miteinander kombinierbar sind, soweit dies technisch möglich ist und kein Widerspruch besteht. So ist es zum Beispiel möglich, Dämpfelemente 12 in dem Rückhaltebereich 3 anzuordnen und die Anzahl der Tragepfosten 5' nicht zu reduzieren.It is expressly pointed out that all the different feature elements of the individual embodiments can be combined with one another as far as is technically possible and there is no contradiction. For example, it is possible to arrange damping
