Description

Steher für ein Fahrzeugrückhaltesystem  Stand for a vehicle restraint system
Die Erfindung betrifft einen Steher für ein Fahrzeugrückhaltesystem gemäß dem Oberbegriff des Patentanspruches 1. The invention relates to an upright for a vehicle restraint system according to the preamble of patent claim 1.
Herkömmliche Fahrzeugrückhaltesysteme weisen in der Regel mehrere, in konstanten Abständen neben der Fahrbahn in den Untergrund gerammte Steher auf, an denen Schutzplanken, meist aus Stahl, befestigt sind. Bei einem Conventional vehicle restraint systems generally have several uprights, rammed into the ground at constant intervals next to the road surface, to which guard rails, usually made of steel, are attached. At a
Anprallereignis, insbesondere bei einem Fahrzeuganprall, verformt sich die Impact event, particularly in the event of a vehicle impact, deforms
Schutzplanke und stützt sich an den Stehern ab, mit denen sie verbunden ist, wodurch sich wiederum die Steher verformen, beginnend im Erdreich, über einen Großteil ihrer Länge. Bei einem starken Anprallereignis löst sich meist auch die Schutzplanke vom Steher, nachdem sich der Steher über einen gewissen Winkel verformt hat. Das Maß für den Widerstand, den eine Schutzplanke dem Anprall eines Fahrzeuges entgegenbringt, ist vor allem vom Abstand der Steher zueinander und von der Biege- und Torsionssteifigkeit der jeweiligen Steher abhängig. Guardrail and is supported on the uprights to which it is connected, which in turn causes the uprights to deform over a large part of their length, starting in the ground. In the event of a strong impact, the crash barrier usually also comes off the post after the post has deformed over a certain angle. The measure of the resistance that a guardrail brings against the impact of a vehicle depends primarily on the distance between the uprights and the bending and torsional rigidity of the respective uprights.
In der Regel wird zur Erhöhung der Widerstandskraft der Schutzplanke auf ein Anprallereignis der Abstand zwischen den einzelnen Stehern verringert und es werden Steher mit Vollprofilen oder mit zumindest geschlossenen Profilen von höherer Stahlgüte verwendet. As a rule, to increase the resistance of the guardrail to an impact event, the distance between the individual uprights is reduced and uprights with full profiles or with at least closed profiles of higher steel quality are used.
Nachteilig daran sind der hohe Materialaufwand und die damit einhergehenden erhöhten Materialkosten sowie deutliche Nachteile bei der Befestigung der Steher im Untergrund, da eine hohe Kraft aufgewendet werden muss, um die Steher in eine gewisse Tiefe in den Boden zu rammen. Vor allem Vollprofile bedingen weiters eine umständliche Montage der Schutzplanke an den Stehern. Disadvantages of this are the high cost of materials and the associated increased material costs, as well as significant disadvantages when fastening the upright to the ground, since a great deal of force has to be used to ram the upright into the ground to a certain depth. Above all, full profiles also require laborious assembly of the guardrail on the uprights.
Aufgabe der Erfindung ist es daher einen Steher der eingangs genannten Art anzugeben, mit welchem die genannten Nachteile vermieden werden können, mit welchem die Widerstandskraft einer Schutzplanke gegen Anprallereignisse bei niedrigem Materialaufwand erhöht wird, sowie eine einfache Befestigung der Steher im Untergrund und eine einfache Montage der Schutzplanke an einem oder an mehreren Stehern zu ermöglichen. The object of the invention is therefore to provide an upright of the type mentioned at the outset, with which the disadvantages mentioned can be avoided, with which the resistance of a guardrail against impact events is increased with a low cost of materials, as well as a simple fastening of the upright in the subsurface and a simple assembly of the To enable guardrail on one or more uprights.
Erfindungsgemäß wird dies durch die Merkmale des Patentanspruches 1 erreicht. Dadurch ergibt sich der Vorteil, dass Materialkosten eingespart werden können, da einerseits keine Profilträger mit Vollprofil benötigt werden, um die According to the invention this is achieved by the features of claim 1. This has the advantage that material costs can be saved since, on the one hand, no profile beams with a full profile are required in order to
Widerstandskraft des Stehers auf Anprallereignisse zu erhöhen und andererseits der Abstand der Steher zueinander nicht verringert werden muss, um die Resistance of the post to impact events and on the other hand the distance between the posts does not need to be reduced in order to
Widerstandskraft der Schutzplanke auf Anprallereignisse zu erhöhen. Der To increase the resistance of the crash barrier to impact events. The
Versteifungsträger kann dann getrennt eingerammt werden. Weiters ist vorteilhaft, dass der zusammengesetzte Querschnitt des Stehers im komplexen dynamischen mehrachsigen und über die Zeitachse richtungsveränderlichen Belastungsvorgang signifikante Vorteile gegenüber einem Steher mit einem Vollprofil bietet. Stiffening beams can then be driven in separately. It is also advantageous that the composite cross section of the upright in the complex dynamic multi-axis loading process that changes direction over the time axis offers significant advantages over an upright with a full profile.

Profilträgers 5 und/oder des Versteifungsträgers 6 ergeben sich vielfältige Profile support 5 and / or the stiffening support 6 are diverse
Anordnungsmöglichkeiten des Versteifungsträgers 6 im Profilträger 5, wie in den Fig.5 bis 10 beispielhaft gezeigt ist. Es kann auch vorgesehen sein, dass der Arrangement possibilities of the stiffening beam 6 in the profile beam 5, as shown by way of example in FIGS. 5 to 10. It can also be provided that the
Profilträger 5 und/oder der Versteifungsträger 6 ein G-Profil aufweisen. Wenn der Profilträger 5 ein U-Profil aufweist, dann kann der Versteifungsträger 6 bei der Öffnung des U-Profils seitlich in den Profilträger 5 eingeschoben werden. Wenn der Profilträger 5 ein C-Profil aufweist, dann kann der Versteifungsträger 6 stirnseitig in den Profilträger 5 eingeschoben werden. Durch die Geometrie des C-Profils des Profilträgers 5 wird der Versteifungsträger 6 im Profilträger 5 gehalten, wodurch sich eine gute Widerstandskraft beziehungsweise eine gute Steifigkeit des Stehers 1 gegen Verdrehungen ergibt. Profile support 5 and / or the stiffening support 6 have a G-profile. If the profile beam 5 has a U-profile, the stiffening beam 6 can be pushed laterally into the profile beam 5 when the U-profile opens. If the profile beam 5 has a C-profile, then the stiffening beam 6 can be inserted into the profile beam 5 on the end face. Due to the geometry of the C-profile of the profile carrier 5, the stiffening carrier 6 is held in the profile carrier 5, which results in a good resistance or a good stiffness of the post 1 against twisting.
Durch das offene Profil des Profilträgers 5 kann der Profilträger 5 einfach in den Untergrund gerammt werden, da im Gegensatz zu einem Vollprofil oder zu einem geschlossenen Profil weniger Fläche des Profilträgers 5 einen Widerstand gegen das Einrammen in den Untergrund leistet. Weiters kann aufgrund des offenen Profils des Profilträgers 5, insbesondere des Stehers 1 , eine Schutzplanke 4 einfach und ohne großen Aufwand an demselben montiert werden. Due to the open profile of the profile carrier 5, the profile carrier 5 can simply be rammed into the ground, since, in contrast to a full profile or to a closed profile, less area of the profile carrier 5 provides resistance to being driven into the ground. Furthermore, due to the open profile of the profile carrier 5, in particular the post 1, a protective barrier 4 can be mounted on the latter simply and without great effort.
Vorzugsweise befindet sich die Öffnung des Profils des Profilträgers 5 an einer der Breitseiten 8 des Profilträgers 5. Dadurch wird im Fall eines Anprallereignisses ein geradliniges und weitgehend verwindungsarmes Verbiegen des Profilträgers 5 erreicht, wodurch sich die Schraube kontrolliert aus der Befestigungsöffnung 12 und somit auch die Schutzplanke 4 kontrolliert vom Steher 1 löst. Preferably, the opening of the profile of the profile carrier 5 is located on one of the broad sides 8 of the profile carrier 5. In the event of an impact, a straightforward and largely torsion-free bending of the profile carrier 5 is achieved, as a result of which the screw is controlled from the fastening opening 12 and thus also the protective barrier 4 controlled from the upright 1 releases.
Es kann weiters bevorzugt vorgesehen sein, dass ein Bereich des Profilträgers 5, in dem die Befestigungseinrichtung 3 angeordnet ist, frei von dem Versteifungsträger 6 ist. Frei bedeutet hierbei, dass sich der Versteifungsträger 6 nicht bis in den Bereich des Profilträgers 5, in dem die Befestigungseinrichtung 3 angeordnet ist, erstreckt. Die Schraube oder der Gewindebolzen kann durch die It can furthermore preferably be provided that an area of the profile support 5, in which the fastening device 3 is arranged, is free of the stiffening support 6. Free here means that the stiffening support 6 does not extend into the area of the profile support 5 in which the fastening device 3 is arranged. The screw or the threaded bolt can be through the
Befestigungseinrichtung 3, insbesondere Befestigungsöffnung 12, des Profilträgers 5 geführt werden und die Mutter kann innerhalb des Profils des Profilträgers 5 verschraubt werden. Vorteilhaft ist hierbei, dass die Schutzplanke 4 einfach am Profilträger 5 montiert werden kann. Die Befestigungsöffnung 12 weist hierbei vorzugsweise einen Aufweitungsbereich auf, in dem die Schraube vorgebbar gelöst werden kann. Vorzugsweise befindet sich der Bereich des Profilträgers 5, der frei von dem Versteifungsträger 6 ist, im, oder wenigstens in der Nähe des Endbereichs 9 des Profilträgers 5. Durch das offene Profil des Profilträgers 5 und den Bereich der Befestigungsöffnung 12, der frei vom Versteifungsträger 6 ist, ergibt sich ein Synergieeffekt, nämlich, dass die Schutzplanke 4 besonders einfach am Profilträger 5 montiert werden kann. Fastening device 3, in particular fastening opening 12, of the profile carrier 5 can be guided and the nut can be screwed within the profile of the profile carrier 5. It is advantageous here that the guardrail 4 simply on Profile carrier 5 can be mounted. The fastening opening 12 preferably has an expansion area in which the screw can be loosened in a predefinable manner. The area of the profile beam 5, which is free of the stiffening beam 6, is preferably located in, or at least in the vicinity of, the end area 9 of the profile beam 5. The open profile of the profile beam 5 and the area of the fastening opening 12, which is free of the stiffening beam 6 there is a synergy effect, namely that the guardrail 4 can be mounted on the profile support 5 in a particularly simple manner.
Es kann bevorzugt vorgesehen sein, dass wenigstens eine Wandfläche des It can preferably be provided that at least one wall surface of the
Versteifungsträgers 6 eine durch das offene Profil bedingte Öffnung des Stiffening girder 6 a due to the open profile opening
Profilträgers 5 abdeckt. Hierdurch ergibt sich der Vorteil, dass Schmutz und weitere Umwelteinflüsse die Innenwandungen des Profilträgers 5 und des Profile carrier 5 covers. This has the advantage that dirt and other environmental influences the inner walls of the profile beam 5 and
Versteifungsträgers 6 an den abgedeckten Stellen nur erschwert und nicht direkt erreichen können, was sich auf die Haltbarkeit, insbesondere durch verminderte Korrosion, der Steher 1 positiv auswirkt.
