Description
Die Erfindung betrifft ein Rückhaltesystem, welches am Boden befestigte Pfosten und an den Pfosten, unter Eingliederung von Distanzelementen, Leitplankenholme aufweist, gemäß dem Oberbegriff des Anspruchs 1, wie aus dem Dokument
Basierend auf den Vergaben des BMV (RPS, RIZ etc.) werden derzeit an Schnellstraßen, Autobahnen und insbesondere auf Brückenbauwerken Stahlschutzplanken und Geländer eingebaut. Durch die Einführung der DIN EN 1317 müssen diese Systeme entsprechend geprüft werden. Herkömmliche Geländerkonstruktionen halten den Prüfbedingungen nicht Stand, so daß diese verstärkt werden müssen und somit auch eine Schutzplanken-Funktion erfüllen, was zur Folge hat, daß separate Schutzplankenkonstruktionen bei bestimmten Bauwerken, insbesondere Überführungen, entbehrlich werden. An den Pfosten sind fahrwegseitig Deformationsprofile sowie Längsholme angebracht. Wenn ein Fahrzeug gegen das Rückhaltesystem fährt, wird zunächst das Deformationsprofil eingedrückt, ohne dass der dahinter liegende Pfosten in Mitleidenschaft gezogen wird. Wenn aufgrund des Anpralls das Deformationsprofil im unteren Bereich vollständig eingedrückt ist, geht die Krafteinwirkung auf den dahinter liegenden Pfosten über.
Diese bekannten Rückhaltesysteme sind kostenintensiv, schwer und genügen nicht den hohen Sicherheitsanforderungen.
Der Erfindung liegt daher, ausgehend vom Stand der Technik, die Aufgabe zugrunde, ein leichtes und kostengünstiges Rückhaltesystem zu schaffen, das die hohen Sicherheitsanforderungen erfüllt.
Die Lösung dieser Aufgabe besteht in der Erfindung eines Rückhaltesystems gemäß Anspruch 1.Based on the award of the BMV (RPS, RIZ etc.) steel barriers and railings are currently being installed on highways, highways and especially on bridge structures. Due to the introduction of DIN EN 1317, these systems must be tested accordingly. Conventional railing constructions do not withstand the test conditions, so that they must be reinforced and thus also fulfill a guard rail function, with the result that separate guard rail structures in certain structures, especially overpasses, are unnecessary. On the posts deformation profiles and longitudinal beams are attached on the way. When a vehicle drives against the restraint system, the deformation profile is first pressed in without the post behind it being affected. If, due to the impact, the deformation profile in the lower area is completely depressed, the force on the post behind goes over.
These known restraint systems are costly, heavy and do not meet the high security requirements.
The invention is therefore, starting from the prior art, the object of the invention to provide a lightweight and cost-effective restraint system that meets the high security requirements.
The solution to this problem consists in the invention of a restraint system according to claim 1.
Dieses Rückhaltesystem besteht aus senkrechten Pfosten mit Fußplatte, welche auf den Bauwerken befestigt werden. Waagerechte Sicherheitselemente als Handlauf sind mit den Pfosten verbunden. Die Leitplankenholme sind über Distanz- oder Dämpfungselemente jeweils mit den Pfosten verbunden. Zwischen den Pfosten sind auch noch Geländerfüllungen angebracht. Auch wenn die Distanz- oder Dämpfungselemente auf unterschiedlichste Art mit den Pfosten bzw. den Leitplankenholmen verbunden sein können, wird eine vorteilhafte Verbindung in einer schraubbaren Verbindung gesehen. Die Befestigung mittels Schrauben ist einfach, zuverlässig und montage- sowie reparaturfreundlich.This restraint system consists of vertical posts with foot plate, which are fixed on the structures. Horizontal security elements as a handrail are connected to the posts. The guard rail spars are connected via spacer or damping elements in each case with the posts. Between the posts are also Geländerfüllungen attached. Even if the spacer or damping elements can be connected in a variety of ways with the posts or the guard rail spars, an advantageous connection is seen in a threaded connection. The fastening by means of screws is simple, reliable and easy to assemble and repair.
Die oberen Dämpfungselemente bestehen aus einem Stahlprofil in Form einer innen offenen '8'. Diese einmal an den Pfosten und zum anderen an den inneren Schenkeln der Leitplankenholme befestigt.
Dieser grundsätzliche Aufbau ist so konzipiert, dass er auf einfache Weise entsprechend der örtlich jeweils geforderten Aufhaltestufe modifiziert werden kann.
Besonders vorteilhaft ist es jedoch, dass dieses Rückhaltesystem sowohl auf einem Mittelstreifen zwischen zwei Fahrwegen als auch randseitig eines Fahrwegs zum Einsatz gelangen kann.The upper damping elements consist of a steel profile in the form of an inside open '8'. These are fastened to the posts once and to the inner thighs of the guardrail bars.
This basic structure is designed so that it can be easily modified according to the locally required retention level.
It is particularly advantageous, however, that this restraint system can be used both on a median strip between two driveways as well as the edge of a guideway.
Der Aufbau des Rückhaltesystems ist einfach und wirtschaftlich. Die zum Einsatz gelangenden Dämpfungselemente erfühlen ihre Funktion zuverlässig. Die Stahlprofile der Dämpfungselemente können rationell in hohen Stückzahlen kostengünstig hergestellt werden. In praktischen Versuchen wurde ein sehr gutes Anfahrverhalten erreicht.The construction of the restraint system is simple and economical. The used damping elements feel their function reliably. The steel profiles of the damping elements can be efficiently produced in large quantities at low cost. In practical experiments, a very good start-up behavior was achieved.
Beim Anprall eines Fahrzeugs wird zunächst mindestens ein Dämpfungselement eingedrückt, ohne dass zugleich der dahinter liegende Pfosten beschädigt wird. Bereits ein großer Teil der Stossenergie kann so durch die Deformation des Dämpfungselements kompensiert werden, ohne daß das Rückhaltesystem durchbrochen wird. Das Unfallfahrzeug wird entlang des Rückhaltesystem geführt. Erst nachdem das Dämpfungselement des unteren Leitplankenstrangs vollständig eingedrückt ist, geht die Krafteinwirkung auf den oberen Leitplankenstrang und den Pfosten über.When a vehicle collides, at least one damping element is first pressed in, without at the same time damaging the post lying behind it. Already a large part of the impact energy can be compensated by the deformation of the damping element, without the restraint system is broken. The accident vehicle is guided along the restraint system. Only after the damping element of the lower guard rail is completely depressed, the force is applied to the upper guard rail and the post over.
Eine vorteilhafte Ausführungsform der erfindungsgemäßen Rückhaltesystem wird entsprechend den Merkmalen des Anspruchs 2 darin gesehen, daß unterhalb der Leitplankenholmes ein zweiter Holm angeordnet ist. Diese Ausführungsform kommt vorzugsweise dann zum Einsatz, wenn zusätzlich ein Unterfahrschutz gefordert ist.An advantageous embodiment of the restraint system according to the invention is seen according to the features of claim 2 in that below the guard rail Holmes, a second spar is arranged. This embodiment is preferably used when an underrun protection is required in addition.
Zur Absorption der Anprallenergie sind in einer weiteren Ausführungsform am Unterfahrschutz des Rückhaltesystem d.h. am unteren Leitplankenholm Distanzelemente, die auch Dämpfungselemente ein können, vorgesehen, die einmal an den Pfosten und zum anderen an den inneren Schenkeln des Leitplankenholmes befestigt sind.For absorbing the impact energy, in another embodiment, the underrun protection of the restraint system, i. at the lower Leitplankenholm spacer elements, which can also a damping elements, provided, which are fixed once to the posts and the other to the inner legs of the guard rail Holmes.
Die oberen Leitplankenholme können sinnvoll in einer mittleren Höhe Ho von 500 mm bis 800 mm zum Fahrweg befestigt werden, vorzugsweise sind sie in einer mittleren Höhe Ho von 600 mm bis 700 mm angebracht.The upper guide rail spars can be usefully attached at a mean height Ho of 500 mm to 800 mm to the driveway, preferably they are mounted at a mean height Ho of 600 mm to 700 mm.
Die unteren Leitplankenholme können sinnvoll in einer mittleren Höhe Hu von 130 mm bis 370 mm zum Fahrweg befestigt werden, vorzugsweise sind sie in einer mittleren Höhe Hu von 200 mm bis 300 mm angebracht.The lower guard rail spars can be usefully attached in a mean height Hu of 130 mm to 370 mm to the track, preferably they are mounted in a mean height Hu from 200 mm to 300 mm.
Ist entlang der Fahrbahn unter anderem ein weiterer Weg vorgesehen, beispielsweise an für Personen besonders gefährlichen Stellen, kann am Rückhaltesystem gemäss Anspruch 6 ein Handlauf, der mit den oberen Enden der Pfosten ist, vorgesehen werden.If, inter alia, another route is provided along the roadway, for example to places which are particularly dangerous for persons, a handrail provided with the upper ends of the posts may be provided on the restraint system according to claim 6.
Dieser Handlauf kann in einer weiteren Ausführungsform ein innenliegendes Stahlseil aufweisen, daß an jedem Pfosten fixiert wird, um ein besseres Zusammenwirken der Pfosten im Falle eines Aufpralls zu bewirken.This handrail, in another embodiment, may include an internal steel cable that is fixed to each post to provide a better interaction of the posts in the event of an impact.
Die Dämpfungselemente können unter anderem aus einem Sonderhohlprofil aus Stahl oder ähnlichem Material bestehen.The damping elements may consist inter alia of a special hollow profile made of steel or similar material.
Die Form des Sonderhohlprofils kann dabei z.B. die einer innen offenen 8 bzw. 6-oder 8-eckig bzw. und oder dieser Formen ähnliche Profile sein.The shape of the special hollow profile may be e.g. which are profiles which are open on the inside or 8 or 6 or 8 and / or of these shapes.

An den Pfosten ( 4 ) sind fahrbahnseitig, unter Eingliederung von Distanz- oder Dämpfungselementen (3a, 3b ) in zwei verschiedenen Höhen Ho, Hu, Leitplankenholme ( 2a, 2b ) festgelegt, wobei der oberen Leitplankenholm ( 2b ) näher zur Fahrbahn hin liegt als der obere Leitplankenholm ( 2a ).That in the
At the posts (4) roadway side, with inclusion of distance or damping elements (3a, 3b) in two different heights Ho, Hu, Leitplankenholme (2a, 2b) set, the upper guard rail spar (2b) closer to the roadway than the upper guard rail spar (2a).
Die Leitplankenholme ( 2a, 2b ) sind aus schussweise aneinander gesetzten Leitplanken (Schüsse) gebildet, welche im Querschnitt eine U-, W-förmige oder ähnliche Konfiguration besitzen.The guard rail spars (2 a, 2 b) are formed from guard rails (shots) which are placed against each other in a weft-like manner, which have a U, W or similar configuration in cross section.
Die Distanz- oder Dämpfungselemente ( 3a, 3b ) sind in ihrer Wirkrichtung waagerecht (siehe
Jeder Pfosten (4) besteht aus einem I-, C-förmigen oder ähnlichen Profil ( z. B. geschlossen ). Der Mittelsteg des Profils erstreckt sich quer zu den Leitplankenholmen ( 2a, 2b ). An den fahrbahnseitigen Steg sind die Distanz- oder Dämpfungselemente angeschraubt oder mit anderen Befestigungsmitteln angebracht.Each post (4) consists of an I, C or similar profile (eg closed). The middle web of the profile extends transversely to the guard rail spars (2a, 2b). At the roadway-side web, the spacer or damping elements are screwed or attached with other fasteners.
Die Leitplankenholme ( 2a, 2b ) sind, wie zuvor beschrieben, in zwei verschiedenen Höhen Ho, Hu festgelegt. Vorzugsweise liegt der obere Leitplankenholm ( 2b ) näher zum Fahrweg als der untere Leitplankenholm (2a). Die Leitplankenholme ( 2a, 2b ) können jedoch auch im gleichen Abstand zur Fahrbahn angebracht werden und der untere Leitplankenholm ( 2a ) kann näher zum Fahrweg als der obere Leitplankenholm ( 2b ) liegen. Vorzugsweise liegt das Verhältnis des Abstands Ao der Vorderseite des oberen Leitplankenstrangs ( 2b ) vom Pfosten ( 4 ) zum Abstand Au der Vorderseite des unteren Leitplankenstrangs 2a zum Pfosten 4 in einem Bereich zwischen 3,0:1 bis 2,0:1, vorzugsweise 2,57:1.The guide rail spars (2a, 2b) are, as previously described, set at two different heights Ho, Hu. Preferably, the upper guard rail spar (2b) is closer to the track than the lower guard rail spar (2a). However, the guide rail spars (2a, 2b) can also be mounted at the same distance from the roadway and the lower guard rail spar (2a) can be closer to the track than the upper guard rail spar (2b). Preferably, the ratio of the distance Ao of the front of the upper guardrail (2b) from the post (4) to the distance Au of the front of the lower guardrail 2a to the
Die an den oberen und unteren Leitplankenholmen ( 2a, 2b ) verwendeten obere und untere Dämpfungselemente (3a, 3b ) können sich hinsichtlich Form, Größe und Steifigkeit sowohl gleichen als auch unterschiedlich sein.The upper and lower damping elements (3a, 3b) used on the upper and lower guard rail spars (2a, 2b) may be the same or different in shape, size and rigidity.
Beim Aufprallvorgang eines Fahrzeugs wird zunächst jeweils der obere Leitplankenholm (2b) kontaktiert. Hierbei werden in Abhängigkeit von der Anprallenergie als erstes Dämpfungselemente (3b) des oberen Leitplankenholms ( 2b ) deformiert, wodurch Stossenergie abgebaut wird. Die Pfosten ( 4 ) bleiben in dieser Deformationsphase weitgehend unbelastet. Der obere Leitplankenholm wird dabei so weit in Richtung zu den Pfosten ( 4 ) verlagert, bis die vom Fahrweg abweisende Rückseite/-fläche am Pfosten ( 4 ) anliegt oder das Dämpfungselement vollständig zusammengedrückt ist. Auf diese Weise bleibt der Pfosten ( 4 ) bis dahin weitgehend ohne großen Krafteinfluß. Erst in einer zweiten Deformationsphase geht die Krafteinwirkung auf den Pfosten ( 4 ) über. Die Leitplankenfunktion bleibt jedoch trotz einer starken Auffahrbelastung nach wie vor erhalten.During the collision process of a vehicle, the upper guard rail spar (2b) is first contacted in each case. In this case, depending on the impact energy, the first damping elements (3b) of the upper guard rail spar (2b) are deformed, as a result of which impact energy is dissipated. The posts (4) remain largely unencumbered in this deformation phase. The upper guard rail spar is displaced so far in the direction of the posts (4) until the repellent away from the track back / surface on the post (4) is applied or the damping element is completely compressed. In this way, the post (4) until then largely without large force influence. Only in a second deformation phase, the force on the post (4) goes over. However, the guardrail function is still maintained despite a strong Auffahrbelastung.
