Description

Die Erfindung betrifft ein Fahrzeugrückhaltesystem umfassend wenigstens einen Steher gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a vehicle restraint system comprising at least one post 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 Anprallereignis, insbesondere bei einem Fahrzeuganprall, verformt sich die 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.Conventional vehicle restraint systems usually have several posts rammed into the ground at constant intervals next to the roadway, to which protective barriers, mostly made of steel, are attached. During a crash event, particularly a vehicle crash, the crash barrier deforms and bears against the posts to which it is connected, which in turn causes the posts to deform, beginning in the ground, for much of their length. In the event of a severe impact event, the crash barrier usually also detaches from the post after the post has deformed over a certain angle. The degree of resistance that a crash barrier offers to the impact of a vehicle depends above all on the distance between the posts and on the flexural and torsional rigidity of the respective posts.

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 crash barrier to an impact event, the distance between the individual uprights is reduced and uprights with solid profiles or at least closed profiles made of higher steel quality are used.

Die DE 20 2006 015 149 U1 offenbart eine Schutzplankenanordnung, umfassend Pfosten, in die Verstärkungsprofile eingefügt sind. Sowohl der Pfosten als auch das Verstärkungsprofil sind als offene Profile ausgestaltet.the DE 20 2006 015 149 U1 discloses a safety barrier assembly comprising posts into which reinforcing profiles are inserted. Both the post and the reinforcement profile are designed as open profiles.

Die FR 2 555 622 A1 zeigt einen Steher für eine Schutzplankenordnung, welcher ein Verstärkungselement für einen C-förmigen Profilträger aufweist.the FR 2 555 622 A1 shows a post for a crash barrier arrangement, which has a reinforcing element for a C-shaped profile beam.

Die KR 20 2012 0001028 U zeigt einen röhrenförmigen Steher zur höhenverstellbaren Montage einer Leitplanke, wobei der Steher einen runden Hauptpfeiler und wenigstens einen Verstärkungspfeiler aufweist.the KR 20 2012 0001028 U shows a tubular post for height-adjustable mounting of a crash barrier, the post having a circular main post and at least one reinforcing post.

Die US 2014/0145132 A1 zeigt ein Fahrzeugrückhaltesystem umfassend Steher, wobei jedoch keine Verstärkungsprofile in die Steher eingefügt sind.the U.S. 2014/0145132 A1 shows a vehicle restraint system including posts, but no reinforcement profiles are inserted into the posts.

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.The disadvantage of this is the high cost of materials and the associated increased material costs as well as significant disadvantages when attaching the posts to the ground, since a great deal of force is required to ram the posts into the ground to a certain depth. Above all, solid profiles also require a cumbersome assembly of the crash barrier on the uprights.

Aufgabe der Erfindung ist es daher ein Fahrzeugrückhaltesystem 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 specify a vehicle restraint system of the type mentioned at the beginning, with which the disadvantages mentioned can be avoided, with which the resistance of a protective barrier against impact events is increased with low material costs, as well as simple fastening of the uprights in the underground and simple assembly of the Allow crash barrier on one or more uprights.

Erfindungsgemäß wird dies durch die Merkmale des Patentanspruches 1 erreicht.According to the invention, this is achieved by the features of patent claim 1.

Dadurch ergibt sich der Vorteil, dass Materialkosten eingespart werden können, da einerseits keine Profilträger mit Vollprofil benötigt werden, um die Widerstandskraft des Stehers auf Anprallereignisse zu erhöhen und andererseits der Abstand der Steher zueinander nicht verringert werden muss, um die Widerstandskraft der Schutzplanke auf Anprallereignisse zu erhöhen. Der 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.This results in the advantage that material costs can be saved, since on the one hand no profile beams with a full profile are required to increase the resistance of the post to impact events and on the other hand the distance between the posts does not have to be reduced to increase the resistance of the crash barrier to impact events raise. The stiffening beam can then be rammed in separately. Furthermore, it is advantageous that the composite cross-section of the post offers significant advantages over a post with a solid profile in the complex, dynamic, multi-axial loading process that changes direction over the time axis.

Die Fig. 1 bis 10 zeigen zumindest Teile von bevorzugten Ausführungsformen eines Stehers 1 für ein Fahrzeugrückhaltesystem 2, wobei der Steher 1 wenigstens eine Befestigungseinrichtung 3 zur Befestigung einer Schutzplanke 4 des Fahrzeugrückhaltesystems 2 aufweist.the Figures 1 to 10 show at least parts of preferred embodiments of a post 1 for a vehicle restraint system 2, the post 1 having at least one fastening device 3 for fastening a protective barrier 4 of the vehicle restraint system 2.

Der Steher 1 ist dazu vorgesehen in einem Untergrund 11 befestigt zu werden, insbesondere in einen Boden gerammt oder geschlagen zu werden und dient dazu, eine Schutzplanke 4 zu halten beziehungsweise zu stützen. Ein Fahrzeugrückhaltesystem 2 weist in der Regel mehrere beabstandet voneinander angeordnete Steher 1 und eine oder mehrere Schutzplanken 4 auf und begrenzt räumlich Fahrbahnen, um schwere Unfälle zu vermindern oder zu vermeiden. Um wenigstens eine Schutzplanke 4 an einem Steher 1 zu befestigen, weist der Steher 1 wenigstens eine Befestigungseinrichtung 3, insbesondere eine Befestigungsöffnung 12, zur Aufnahme wenigstens einer Schraube oder eines Gewindebolzens auf. Die Schraube oder der Gewindebolzen werden durch die Schutzplanke 4 und durch die wenigstens eine Befestigungsöffnung 12 des Stehers 1 geführt und verschraubt, um die Schutzplanke 4 am Steher 1 zu befestigen. Es kann auch vorgesehen sein, dass die Schutzplanke 4 mittels eines Hakens oder einer Klammer am Steher 1 befestigt ist.The post 1 is intended to be fastened to a subsurface 11, in particular to be rammed or hit into the ground, and is used to hold or support a crash barrier 4. A vehicle restraint system 2 generally has a plurality of uprights 1 arranged at a distance from one another and one or more crash barriers 4 and spatially delimits roadways in order to reduce or avoid serious accidents. In order to attach at least one crash barrier 4 to a post 1, the post 1 has at least one fastening device 3, in particular a fastening opening 12, for receiving at least one screw or a threaded bolt. The screw or the threaded bolt is guided through the protective barrier 4 and through the at least one fastening opening 12 of the post 1 and screwed in order to fasten the protective barrier 4 to the post 1 . Provision can also be made for the protective barrier 4 to be fastened to the post 1 by means of a hook or a clamp.

Es ist vorgesehen, dass der Steher 1 einen Profilträger 5 und einen in dem Profilträger 5 angeordneten Versteifungsträger 6 umfasst, und dass die Längsachse des Versteifungsträgers 6 im Wesentlichen parallel zur Längsachse des Profilträgers 5 angeordnet ist.It is provided that the post 1 comprises a profiled beam 5 and a stiffening beam 6 arranged in the profiled beam 5 , and that the longitudinal axis of the stiffening beam 6 is arranged essentially parallel to the longitudinal axis of the profiled beam 5 .

Der Versteifungsträger 6 fungiert als Verstärkungselement für den Profilträger 5. Mit anderen Worten, der im Profilträger 5 angeordnete Versteifungsträger 6 erhöht das Widerstandsmoment beziehungsweise die Biege- und Torsionssteifigkeit des Stehers 1. Es ist bevorzugt vorgesehen, dass der Versteifungsträger 6 eine Breite aufweist, die nur unwesentlich kleiner als eine Breite des Profilträgers 5 ist. Es ist weiters bevorzugt vorgesehen, dass das Profil des Profilträgers 5 über dessen Länge gleich bleibt. Es kann auch bevorzugt vorgesehen sein, dass das Profil des Versteifungsträgers 6 über dessen Länge gleich bleibt.The stiffening beam 6 acts as a reinforcement element for the profile beam 5. In other words, the stiffening beam 6 arranged in the profile beam 5 increases the section modulus or the flexural and torsional rigidity of the post 1. It is preferably provided that the stiffening beam 6 has a width that is only is slightly smaller than a width of the profile beam 5. Provision is also preferably made for the profile of the profiled beam 5 to remain the same over its length. Provision can also preferably be made for the profile of the stiffening beam 6 to remain the same over its length.

Dadurch ergibt sich der Vorteil, dass Materialkosten eingespart werden können, da einerseits keine Profilträger mit Vollprofil benötigt werden, um die Widerstandskraft des Stehers auf Anprallereignisse zu erhöhen und andererseits der Abstand der Steher zueinander nicht verringert werden muss, um die Widerstandskraft der Schutzplanke auf Anprallereignisse zu erhöhen. Der 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.This results in the advantage that material costs can be saved, since on the one hand no profile beams with a full profile are required to increase the resistance of the post to impact events and on the other hand the distance between the posts does not have to be reduced to increase the resistance of the crash barrier to impact events raise. The stiffening beam can then be rammed in separately. Furthermore, it is advantageous that the composite cross-section of the post offers significant advantages over a post with a solid profile in the complex, dynamic, multi-axial loading process that changes direction over the time axis.

Weiters ist ein Fahrzeugrückhaltesystem 2 umfassend den wenigstens einen Steher 1 vorgesehen, wobei wenigstens eine Schutzplanke 4 an dem wenigstens einen Steher 1 mittels der Befestigungseinrichtung 3 befestigt ist.Furthermore, a vehicle restraint system 2 comprising the at least one post 1 is provided, with at least one crash barrier 4 being fastened to the at least one post 1 by means of the fastening device 3 .

Fig. 1 zeigt einen Ausschnitt einer bevorzugten Ausführungsform des Fahrzeugrückhaltesystems 2 in perspektivischer Ansicht, umfassend mehrere Steher 1, die jeweils aus einem Profilträger 5 und einem in dem Profilträger 5 angeordneten Versteifungsträger 6 bestehen, wobei die Steher 1 in einem Untergrund 11 befestigt sind, sowie Schutzplanken 4, die mittels Schrauben und entsprechenden Muttern an Befestigungseinrichtungen 3 am jeweiligen Endbereich 9 der Profilträger 5 der jeweiligen Steher 1 befestigt sind. Die Schrauben ragen durch die jeweiligen Schutzplanken 4 und durch die jeweiligen fluchtend angeordneten Befestigungseinrichtungen 3, insbesondere Befestigungsöffnungen 12, der Steher 1. 1 shows a section of a preferred embodiment of the vehicle restraint system 2 in a perspective view, comprising a plurality of uprights 1, each consisting of a profiled beam 5 and a stiffening beam 6 arranged in the profiled beam 5, the uprights 1 being fastened to a substrate 11, as well as crash barriers 4, which are fastened by means of screws and corresponding nuts to fastening devices 3 at the respective end region 9 of the profiled beam 5 of the respective post 1. The screws protrude through the respective protective barriers 4 and through the respective aligned fastening devices 3, in particular fastening openings 12, of the post 1.

Bevorzugt kann vorgesehen sein, dass sich in einem Montagezustand mehr als die Hälfte der Länge des Stehers 1 im Untergrund 11 befindet. Mit Untergrund 11 ist hierbei ein Boden, insbesondere ein Boden am Fahrbahnrand einer Straße, oder beispielsweise ein, zwei Fahrbahnen trennender Mittelstreifen, insbesondere bei einer mehrspurigen Autobahn mit Gegenverkehr, gemeint.Provision can preferably be made for more than half the length of the upright 1 to be located in the subsurface 11 in an assembled state. The subsurface 11 here means a floor, in particular a floor at the edge of a road, or for example a median strip separating two lanes, in particular in the case of a multi-lane motorway with oncoming traffic.

Es kann vorgesehen sein, dass Schutzplanken 4 mit beispielsweise einem A-Profil oder mit einem B-Profil an den Stehern 1 befestigt sind. Es kann auch vorgesehen sein, dass die Steher 1, insbesondere die Profilträger 5 der Steher 1 weitere Befestigungsöffnungen 12 aufweisen, an denen ein Unterfahrschutz befestigt werden kann. Ein Unterfahrschutz soll schwere Verletzungen von Motorradfahrern, die bei Unfällen unter die Schutzplanken 4 rutschen können, verhindern.Provision can be made for protective barriers 4 to be fastened to the uprights 1 with, for example, an A profile or a B profile. Provision can also be made for the uprights 1, in particular the profile supports 5 of the uprights 1, to have further fastening openings 12, to which an underrun protection is fastened can be. An underride protection is intended to prevent serious injuries to motorcyclists who could slip under the crash barriers 4 in the event of an accident.

Es kann auch vorgesehen sein, dass der Profilträger 5 und/oder der Versteifungsträger 6 mehr als eine Befestigungseinrichtung 3 zur Befestigung einer Schutzplanke 4 aufweist.It can also be provided that the profiled beam 5 and/or the stiffening beam 6 has more than one fastening device 3 for fastening a crash barrier 4 .

Das Verdrehen des Stehers 1 bei einem Anprallereignis kann ein Verkanten und Verhaken der Befestigungseinrichtung 3 in der Befestigungsöffnung 12 bewirken, wodurch sich die Schutzplanke 4 nicht vom Steher 1 löst. Um eine Verdrehung des Stehers 1 bei einer Biegebeanspruchung zu vermeiden, ist vorgesehen dass der Profilträger 5 zwei Schmalseiten 7 und zwei Breitseiten 8 aufweist, wobei an wenigstens einer der Schmalseiten 7 des Profilträgers 5 wenigstens eine Befestigungseinrichtung 3 angeordnet ist.The twisting of the post 1 in the event of an impact can cause the fastening device 3 to tilt and catch in the fastening opening 12, as a result of which the crash barrier 4 does not become detached from the post 1. In order to prevent the upright 1 from twisting under bending stress, the profile support 5 has two narrow sides 7 and two broad sides 8 , with at least one fastening device 3 being arranged on at least one of the narrow sides 7 of the profile support 5 .

Um die Wahrscheinlichkeit des Verdrehens des Stehers 1 bei einem Anprallereignis weiter zu minimieren ist vorgesehen, dass der Profilträger 5 und der Versteifungsträger 6 mittels einer Verbindungseinrichtung 10 lösbar miteinander befestigt sind. Somit ist es möglich, beide Träger 5, 6 einfach voneinander zu lösen und mit einer definierten Vorspannung, insbesondere mit einem definierten Anzugsdrehmoment, zu verbinden. Die Befestigungseinrichtung 3 und die Verbindungseinrichtung 10 sind somit unterschiedlich. Die lösbare Befestigung des Profilträgers 5 mit dem Versteifungsträger 6 bietet weiters den Vorteil, dass im Falle eines deformierten Profilträgers 5 und eines intakten Versteifungsträgers 6, der Versteifungsträger 6 in einem neuen Profilträger 5 befestigt werden kann. Als weiterer Vorteil ergibt sich, dass der Profilträger 5 und der Versteifungsträger 6 getrennt voneinander in den Boden eingerammt oder eingeschlagen werden können, wodurch weniger Kraft benötigt wird, als wenn beide Träger 5, 6 zusammen in den Boden eingerammt oder eingeschlagen werden. Die jeweiligen Profilträger 5 und Versteifungsträger 6 der jeweiligen Steher des Fahrzeugrückhaltesystems 2 sind jeweils mittels wenigstens einer Verbindungseinrichtung 10 miteinander verbunden beziehungsweise aneinander befestigt.In order to further minimize the probability of the upright 1 twisting in the event of an impact, provision is made for the profiled beam 5 and the stiffening beam 6 to be detachably fastened to one another by means of a connecting device 10 . It is thus possible to easily detach the two carriers 5, 6 from one another and to connect them with a defined preload, in particular with a defined tightening torque. The fastening device 3 and the connecting device 10 are therefore different. The detachable fastening of the profiled beam 5 to the stiffening beam 6 also offers the advantage that, in the case of a deformed profiled beam 5 and an intact stiffening beam 6, the stiffening beam 6 can be fastened in a new profiled beam 5. A further advantage is that the profile beam 5 and the stiffening beam 6 can be rammed or driven into the ground separately, which means that less force is required than if both beams 5, 6 are rammed or driven into the ground together. The respective profile supports 5 and stiffening supports 6 of the respective uprights of the vehicle restraint system 2 are each connected to one another or fastened to one another by means of at least one connecting device 10 .

Es kann bevorzugt vorgesehen sein, dass zwischen dem Profilträger 5 und dem Versteifungsträger 6 ein Spiel vorhanden ist, wobei der Versteifungsträger 6 mittels der Verbindungseinrichtung 10 im Profilträger 5 befestigt ist. Hierzu kann vorgesehen sein, dass der Versteifungsträger 6 ohne großen Kraftaufwand im Profilträger 5 anordenbar ist.Provision can preferably be made for there to be play between the profiled beam 5 and the stiffening beam 6 , with the stiffening beam 6 being fastened in the profiled beam 5 by means of the connecting device 10 . For this purpose, it can be provided that the stiffening support 6 can be arranged in the profile support 5 without great expenditure of force.

Besonders bevorzugt kann vorgesehen sein, dass die wenigstens eine Verbindungseinrichtung 10 den Versteifungsträger 6 und den Profilträger 5 formschlüssig miteinander verbindet. Hierzu kann vorgesehen sein, dass der Profilträger 5 eine Öffnung und der Versteifungsträger 6 einen Federstift aufweist, wobei der Federstift in der Öffnung einrastet.Provision can particularly preferably be made for the at least one connecting device 10 to connect the stiffening support 6 and the profile support 5 with one another in a form-fitting manner. For this purpose it can be provided that the profile support 5 has an opening and the stiffening support 6 has a spring pin, the spring pin snapping into the opening.

Durch die lösbare Befestigung der Träger 5, 6 aneinander mittels der Verbindungseinrichtung 10 wird der Widerstand der Träger 5, 6 und entsprechend der Widerstand des Stehers 1 auf Verbiegungen und Verdrehungen, insbesondere die Biegesteifigkeit des Stehers 1, signifikant erhöht, da eine schubsteife Verbindung zwischen den Trägern 5, 6 hergestellt wird, wodurch der Steher 1 bei einem Anprallereignis wesentlich stabiler ist, als ohne Verbindungseinrichtung 10.The detachable attachment of the beams 5, 6 to one another by means of the connecting device 10 significantly increases the resistance of the beams 5, 6 and, accordingly, the resistance of the post 1 to bending and twisting, in particular the flexural rigidity of the post 1, since a shear-resistant connection between the beams 5, 6, whereby the post 1 is significantly more stable in the event of an impact than without a connecting device 10.

Es kann weiters bevorzugt vorgesehen sein, dass der Versteifungsträger 6 und der Profilträger 5 fluchtend angeordnete Verbindungsöffnungen aufweisen und dass die Verbindungseinrichtung 10 beide Verbindungsöffnungen durchgreift, wie in Fig. 9 und 10 beispielhaft abgebildet ist. Es kann jedoch auch bevorzugt vorgesehen sein, dass der Profilträger 5 und der Versteifungsträger 6 an beiden Schmalseiten 7 fluchtend angeordnete Verbindungsöffnungen aufweisen und die Verbindungseinrichtung 10 durch alle vier Verbindungsöffnungen durchgreift, wie in Fig. 6 und 8 beispielhaft gezeigt ist. Es kann weiters vorgesehen sein, dass der Versteifungsträger 6 im Profilträger 5 beweglich anordenbar ist, um die wenigstens eine Verbindungsöffnung des Versteifungsträgers 6 mit der Verbindungsöffnung des Profilträger 5 fluchtend anzuordnen, um die Verbindungseinrichtung 10 durch beide Verbindungsöffnungen durchführen zu können. Mittels der Verbindungseinrichtung 10, insbesondere bei der Verschraubung der Verbindungseinrichtung 10, werden bei der Befestigung der Träger 5, 6 aneinander die Schmalseiten 7, insbesondere die Profilschenkel der Schmalseiten 7, des Profilträgers 5 gegen den Versteifungsträger 6 gedrückt, wodurch ein zusammengesetzter Träger, ein sogenannter Verbundträger, durch Formschluss geschaffen wird.Provision can also preferably be made for the stiffening beam 6 and the profiled beam 5 to have connecting openings which are arranged in alignment and for the connecting device 10 to pass through both connecting openings, as shown in FIG Figures 9 and 10 is shown as an example. However, it can also preferably be provided that the profiled beam 5 and the stiffening beam 6 have connecting openings arranged in alignment on both narrow sides 7 and that the connecting device 10 extends through all four connecting openings, as shown in FIG 6 and 8th is shown as an example. It can further be provided that the stiffening beam 6 can be arranged movably in the profiled beam 5 in order to arrange the at least one connection opening of the stiffening beam 6 flush with the connecting opening of the profiled beam 5 in order to be able to guide the connecting device 10 through both connecting openings. By means of the connecting device 10, in particular when the connecting device 10 is screwed together, the narrow sides 7, in particular the profile legs of the narrow sides 7, of the profiled beam 5 are pressed against the stiffening beam 6 when the beams 5, 6 are fastened to one another, whereby a composite beam, a so-called Composite beam is created by positive locking.

Es kann auch vorgesehen sein, dass der Versteifungsträger 6 und der Profilträger 5 jeweils mehrere Verbindungsöffnungen aufweisen, die fluchtend anordenbar sind und durch die mehrere Verbindungseinrichtungen 10 geführt werden können, um die Träger 5, 6 lösbar aneinander zu befestigen. Entsprechend können die Träger 5, 6 mittels zwei, drei oder mehr als drei Verbindungseinrichtungen 10 miteinander befestigt sein.It can also be provided that the stiffening beam 6 and the profiled beam 5 each have a plurality of connecting openings which can be arranged in alignment and through which a plurality of connecting devices 10 can be guided in order to fasten the beams 5, 6 to one another in a detachable manner. Correspondingly, the carriers 5, 6 can be fastened to one another by means of two, three or more than three connecting devices 10.

Es kann insbesondere vorgesehen sein, dass der Versteifungsträger 6 und der Profilträger 5 kraft- oder reibschlüssig miteinander verbunden sind. Hierbei liegen die Schmalseiten 7 und wenigstens Teile der Breitseiten 8 des Profilträgers 5 und des Versteifungsträgers 6 flächig aneinander, wie in Fig. 5 bis 10 beispielhaft veranschaulicht ist. Durch das flächige Anliegen von zumindest Teilen der Schmalseite 7 und/oder der Breitseite 8 der jeweiligen Träger 5, 6 wird die Reibung zwischen den Trägern 5, 6 und entsprechend die Stabilität des Stehers 1 erhöht.In particular, it can be provided that the stiffening support 6 and the profile support 5 are connected to one another in a non-positive or frictional manner. Here, the narrow sides 7 and at least parts of the broad sides 8 of the profiled beam 5 and the stiffening beam 6 lie flat against one another, as in Figures 5 to 10 is exemplified. The fact that at least parts of the narrow side 7 and/or the broad side 8 of the respective supports 5, 6 are in contact over a large area increases the friction between the supports 5, 6 and accordingly the stability of the post 1.

Weiters kann bevorzugt vorgesehen sein, dass der Versteifungsträger 6 mittels der Verbindungseinrichtung 10 in den Profilträger 5 vorgebbar eingeklemmt ist. Durch das Einklemmen des Versteifungsträgers 6 im Profilträger 5 wird die Reibung zwischen Versteifungsträger 6 und Profilträger 5 erhöht. Mittels der Verbindungseinrichtung 10 wird Kraft auf den Profilträger 5, insbesondere auf wenigstens einen Profilschenkel des Profilträgers 5 an wenigstens einer Schmalseite 7 des Profilträgers 5 ausgeübt. Hierzu wird insbesondere eine Schraube, die durch die entsprechenden Verbindungsöffnungen der Schmalseiten der Träger 5,6 reicht, mit einer entsprechenden Mutter, die sich außen auf einer Schmalseite des Profilträgers 5 befindet, verschraubt. Es kann auch vorgesehen sein, dass mittels einer Schraubklemme der Versteifungsträger 6 im Profilträger 5 eingeklemmt wird. Von einem oder von beiden Profilschenkeln des Profilträgers 5 wird letztendlich Druck auf den, im Profil des Profilträger 5 befindlichen, Versteifungsträger 6 ausgeübt und dieser somit im Profilträger 5 eingeklemmt.Furthermore, it can preferably be provided that the stiffening support 6 is clamped into the profile support 5 in a predetermined manner by means of the connecting device 10 . By clamping the stiffening beam 6 in the profile beam 5, the friction between the stiffening beam 6 and the profile beam 5 is increased. By means of the connecting device 10, force is exerted on the profile carrier 5, in particular on at least one profile leg of the profile carrier 5 on at least one narrow side 7 of the profile carrier 5. For this purpose, in particular, a screw that extends through the corresponding connection openings in the narrow sides of the carrier 5 , 6 is screwed to a corresponding nut that is located outside on a narrow side of the profile carrier 5 . Provision can also be made for the reinforcement beam 6 to be clamped in the profile beam 5 by means of a screw clamp. One or both profile legs of the profile carrier 5 ultimately exert pressure on the stiffening carrier 6 located in the profile of the profile carrier 5 and this is thus clamped in the profile carrier 5 .

Mittels der Verbindungseinrichtung 10 kann somit der Druck des Profilträgers 5 auf den Versteifungsträger 6 eingestellt werden, indem beispielsweise eine Schraube und die entsprechende Mutter oder beispielsweise eine Schraubklemme festgezogen wird.The pressure of the profiled beam 5 on the stiffening beam 6 can thus be adjusted by means of the connecting device 10, for example by a screw and the corresponding nut or, for example, a screw clamp is tightened.

Bevorzugt kann vorgesehen sein, dass die Länge des Versteifungsträgers 6 kürzer ist als die Länge des Profilträgers 5. Somit können einerseits Materialkosten eingespart werden und andererseits kann die Biege- und Torsionssteifigkeit des Stehers 1 aufgrund der Länge des Versteifungsträgers 6 selektiv eingestellt werden. In Fig. 2 ist ein Versteifungsträger 6, der dieselbe Länge wie der Profilträger 5 aufweist, beispielhaft abgebildet, wobei der Steher mit mehr als der Hälfte seiner Länge im Untergrund 11 befestigt ist.It can preferably be provided that the length of the stiffening beam 6 is shorter than the length of the profiled beam 5. Thus, on the one hand, material costs can be saved and, on the other hand, the flexural and torsional rigidity of the upright 1 can be selectively adjusted due to the length of the stiffening beam 6. In 2 a stiffening beam 6, which has the same length as the profile beam 5, is shown as an example, the upright being fastened to the ground 11 with more than half of its length.

Es kann weiters vorgesehen sein, dass der Profilträger 5 und/oder der Versteifungsträger 6 ein durchgehendes konstantes Profil aufweisen.Provision can also be made for the profiled beam 5 and/or the stiffening beam 6 to have a continuous, constant profile.

Um die Biegesteifigkeit des Stehers 1 im Untergrund 11 beziehungsweise in der Nähe des Untergrunds zu erhöhen, kann bevorzugt vorgesehen sein, dass sowohl der Profilträger 5 als auch der Versteifungsträger 6 im Untergrund 11 befestigt sind, was in Fig. 1 beispielhaft gezeigt ist. Diesbezüglich kann vorgesehen sein, dass mehr als die Hälfte der Länge des Profilträgers 5 und wenigstens ein Drittel, bevorzugt wenigstens die Hälfte der Länge des Versteifungsträgers 6 im Untergrund 11 befestigt sind. Es kann aber auch vorgesehen sein, dass maximal 50%, insbesondere maximal 30% und bevorzugt maximal 20% des Versteifungsträgers 6 im Untergrund 11 befestigt sind.In order to increase the flexural rigidity of the post 1 in the substructure 11 or in the vicinity of the substructure, it can preferably be provided that both the profile beam 5 and the stiffening beam 6 are fastened in the substructure 11, which is shown in 1 is shown as an example. In this regard, it can be provided that more than half the length of the profiled beam 5 and at least a third, preferably at least half, of the length of the stiffening beam 6 are fastened in the substructure 11 . However, it can also be provided that a maximum of 50%, in particular a maximum of 30% and preferably a maximum of 20% of the stiffening support 6 is fastened in the substructure 11 .

Überraschenderweise hat sich gezeigt, dass nicht die gesamte Länge des Profilträgers 5 mittels des Versteifungsträgers 6 verstärkt werden muss, um eine deutliche Erhöhung der Torsions- und Biegesteifigkeit des Stehers 1 zu erlangen. Bevorzugt ist der Profilträger 5 vor allem im oberen Bereich, also im Bereich über dem Untergrund 11 mit dem Versteifungsträger 6 verstärkt, wobei nur ein Teil des Versteifungsträgers 6 in den Untergrund 11 ragen muss. Um die Widerstandskraft des Stehers 1 auf Anprallereignisse weiter zu erhöhen, ragt der Profilträger 5 insbesondere über minimal 30%, bevorzugt über minimal 50%, besonders bevorzugt über minimal 70%,seiner Länge im Montagezustand in den Untergrund 11. Fig. 3 zeigt beispielhaft einen Versteifungsträger 6, der in einem Profilträger 5 angeordnet ist, wobei der Versteifungsträger 6 etwas länger als die Hälfte der Länge des Profilträgers 5 ist, wobei etwa weniger als ein Drittel der Länge des Versteifungsträgers 6 in den Untergrund 11 reichen.Surprisingly, it has been shown that the entire length of the profiled beam 5 does not have to be reinforced by means of the stiffening beam 6 in order to achieve a significant increase in the torsional and flexural rigidity of the post 1 . The profiled beam 5 is preferably reinforced with the stiffening beam 6 above all in the upper area, that is to say in the area above the base 11 , with only part of the stiffening beam 6 having to protrude into the base 11 . In order to further increase the resistance of the post 1 to impact events, the profile beam 5 protrudes in particular over a minimum of 30%, preferably over a minimum of 50%, particularly preferably over a minimum of 70% of its length in the installed state into the substructure 11. 3 shows an example of a stiffening beam 6, which is arranged in a profile beam 5, wherein the stiffening beam 6 is slightly longer than half of the Length of the profile beam 5 is, with about less than a third of the length of the stiffening beam 6 in the ground 11 rich.

Es kann bevorzugt vorgesehen sein, dass sich der Versteifungsträger 6 über maximal 50%, bevorzugt über maximal 70%, besonders bevorzugt über maximal 90%, der Länge des Profilträgers 5 erstreckt. Es kann auch vorgesehen sein, dass sich der Versteifungsträger 6 über minimal 40%, bevorzugt über minimal 60%, besonders bevorzugt über minimal 80% der Länge des Profilträgers 5 erstreckt.Provision can preferably be made for the stiffening beam 6 to extend over a maximum of 50%, preferably over a maximum of 70%, particularly preferably over a maximum of 90%, of the length of the profiled beam 5 . Provision can also be made for the stiffening beam 6 to extend over a minimum of 40%, preferably over a minimum of 60%, particularly preferably over a minimum of 80% of the length of the profiled beam 5 .

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. In Fig. 4 ist beispielhaft ein Steher 1 in Rückansicht, beziehungsweise eine Breitseite 8 des Profilträgers 5 und ein im Profilträger 5 angeordneter Versteifungsträger 6, abgebildet, wobei der Steher 1 in den Untergrund 11 eingerammt ist, wobei ein Bereich des Profilträgers 5, in dem die Befestigungseinrichtung 3 angeordnet ist, frei von dem Versteifungsträger 6 ist. Die Befestigungseinrichtung 3 ist in Fig. 4 insofern nicht abgebildet, da diese an einer oder an beiden Schmalseiten 7 des Profilträgers 5 angeordnet ist. Die Schraube oder der Gewindebolzen kann durch die 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.Provision can furthermore preferably be made for a region of the profiled beam 5 in which the fastening device 3 is arranged to be free of the stiffening beam 6 . In this context, free 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. In 4 shows an example of a post 1 in a rear view, or a broad side 8 of the profiled beam 5 and a stiffening beam 6 arranged in the profiled beam 5, with the post 1 being rammed into the substructure 11, with a region of the profiled beam 5 in which the fastening device 3 being arranged is, free from the stiffening beam 6 is. The fastening device 3 is in 4 not shown insofar as it is arranged on one or both narrow sides 7 of the profiled beam 5 . The screw or the threaded bolt can be guided through the fastening device 3, in particular the fastening opening 12, of the profile carrier 5 and the nut can be screwed inside the profile of the profile carrier 5. The advantage here is that the protective barrier 4 can be easily mounted on the profiled beam 5 . The fastening opening 12 preferably has a widened area in which the screw can be loosened in a predetermined manner. The area of the profiled beam 5 that is free of the stiffening beam 6 is preferably located in, or at least in the vicinity of, the end area 9 of the profiled beam 5.

Besonders bevorzugt kann vorgesehen sein, dass der Profilträger 5 ein offenes Profil, insbesondere ein C-Profil oder ein U-Profil, aufweist. Weiters kann bevorzugt vorgesehen sein, dass der Versteifungsträger 6 ein offenes Profil, insbesondere ein C-Profil oder ein U-Profil aufweist. Ein offenes Profil bedeutet hierbei, dass das Profil zumindest eine sich über die Länge des Profils erstreckende Öffnung aufweist. Bevorzugt kann hierzu vorgesehen sein, dass das offene Profil des Profilträgers 5 wenigstens abschnittsweise eine Aufnahme für den Versteifungsträger 6 ausbildet. Durch das C-Profil oder das U-Profil des Profilträgers 5 und/oder des Versteifungsträgers 6 ergeben sich vielfältige Anordnungsmöglichkeiten des Versteifungsträgers 6 im Profilträger 5, wie in den Fig.5 bis 10 beispielhaft gezeigt ist. Es kann auch vorgesehen sein, dass der 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.Particularly preferably, it can be provided that the profile carrier 5 has an open profile, in particular a C profile or a U profile. Furthermore, it can preferably be provided that the stiffening support 6 has an open profile, in particular a C-profile or a U-profile. An open profile here means that the profile has at least one opening extending over the length of the profile. It can preferably be provided for this that the open profile of the profiled beam 5 forms a receptacle for the stiffening beam 6 at least in sections. The C-profile or the U-profile of the profiled beam 5 and/or the stiffening beam 6 result in a wide range of possible arrangements for the stiffening beam 6 in the profiled beam 5, as in FIGS Figures 5 to 10 is shown as an example. It can also be provided that the profiled beam 5 and/or the stiffening beam 6 have a G-profile. If the profiled support 5 has a U-profile, then the stiffening support 6 can be pushed laterally into the profiled support 5 when the U-profile is opened. If the profile support 5 has a C-profile, then the stiffening support 6 can be pushed into the profile support 5 at the front. Due to the geometry of the C-profile of the profiled beam 5, the stiffening beam 6 is held in the profiled beam 5, resulting in good resistance or good rigidity 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 profiled beam 5, the profiled beam 5 can simply be rammed into the ground, since, in contrast to a full profile or a closed profile, less surface area of the profiled beam 5 offers resistance to being rammed into the ground. Furthermore, due to the open profile of the profiled beam 5, in particular the post 1, a crash barrier 4 can be mounted on the same easily 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.The opening in the profile of the profile support 5 is preferably located on one of the broad sides 8 of the profile support 5. In the event of an impact, this results in a straight and largely torsion-free bending of the profile support 5, which means that the screw escapes in a controlled manner from the fastening opening 12 and thus also the crash barrier 4 controlled by the stayer 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 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.Provision can furthermore preferably be made for a region of the profiled beam 5 in which the fastening device 3 is arranged to be free of the stiffening beam 6 . In this context, free 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 guided through the fastening device 3, in particular the fastening opening 12, of the profile carrier 5 and the nut can be screwed inside the profile of the profile carrier 5. The advantage here is that the crash barrier 4 simply on Profile carrier 5 can be mounted. The fastening opening 12 preferably has a widened area in which the screw can be loosened in a predetermined manner. The area of the profiled beam 5 that is free of the stiffening beam 6 is preferably located in or at least in the vicinity of the end area 9 of the profiled beam 5. The open profile of the profiled beam 5 and the area of the fastening opening 12 that is free of the stiffening beam 6 is, there is a synergy effect, namely that the crash barrier 4 can be mounted on the profile carrier 5 particularly easily.

Es kann bevorzugt vorgesehen sein, dass wenigstens eine Wandfläche des Versteifungsträgers 6 eine durch das offene Profil bedingte Öffnung des Profilträgers 5 abdeckt. Hierdurch ergibt sich der Vorteil, dass Schmutz und weitere Umwelteinflüsse die Innenwandungen des Profilträgers 5 und des 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. In Fig. 5 sind ein Profilträger 5 und ein Versteifungsträger 6 mit jeweils einem U-Profil beispielhaft dargestellt. Der Versteifungsträger 6 ist in Bezug auf den Profilträger 5 um 180° gedreht im Profil des Profilträgers 5 angeordnet, wobei der Versteifungsträger 6 die Öffnung des Profils Profilträgers 5 durch eine Wandfläche abdeckt.Provision can preferably be made for at least one wall surface of the stiffening support 6 to cover an opening in the profile support 5 caused by the open profile. This has the advantage that dirt and other environmental influences can only reach the inner walls of the profiled beam 5 and the stiffening beam 6 with difficulty and not directly at the covered points, which has a positive effect on the durability, in particular due to reduced corrosion, of the post 1 . In figure 5 a profile carrier 5 and a stiffening carrier 6, each with a U-profile, are shown as an example. The stiffening beam 6 is arranged rotated by 180° in relation to the profile beam 5 in the profile of the profile beam 5, with the stiffening beam 6 covering the opening of the profile of the profile beam 5 by a wall surface.

Fig. 6 zeigt beispielhaft einen Versteifungsträger 6 mit einem U-Profil, der in dem C-Profil eines Profilträgers 5 angeordnet ist. Der Profilträger 5 und der Versteifungsträger 6 weisen jeweils an beiden Schmalseiten 7 fluchtend angeordnete Verbindungsöffnungen auf und die Verbindungseinrichtung 10, insbesondere bestehend aus einer Schraube und einer Mutter, greift durch alle vier Verbindungsöffnungen hindurch. Die fluchtend angeordneten Verbindungsöffnungen sind in den Fig. 1 bis 10 nicht veranschaulicht. Der Versteifungsträger 6 ist in Bezug auf die Ausrichtung des Profilträgers 5 um 180° gedreht in demselben angeordnet, wobei der Versteifungsträger 6 die Öffnung des Profils des Profilträgers 5 durch wenigstens eine Wandfläche abdeckt. 6 shows an example of a stiffening beam 6 with a U-profile, which is arranged in the C-profile of a profile beam 5. The profiled beam 5 and the stiffening beam 6 each have connecting openings arranged in alignment on both narrow sides 7 and the connecting device 10, consisting in particular of a screw and a nut, extends through all four connecting openings. The aligned connecting openings are in the Figures 1 to 10 not illustrated. The stiffening support 6 is arranged in the profile support 5 rotated by 180° with respect to the orientation of the same, the stiffening support 6 covering the opening of the profile of the profile support 5 with at least one wall surface.

In Fig. 7 sind ein Profilträger 5 und ein Versteifungsträger 6 mit jeweils einem C-Profil beispielhaft abgebildet, wobei das Profil des Versteifungsträgers 6 formschlüssig und parallel zur Ausrichtung des Profilträgers 5 in demselben angeordnet ist. Die Öffnung des C-Profils des Versteifungsträgers 6 ist somit parallel zur Öffnung des C-Profils des Profilträgers 5.In 7 are a profile beam 5 and a stiffening beam 6, each with a C-profile shown as an example, the profile of the stiffening beam 6 positively and parallel to the alignment of the profile beam 5 in the same is arranged. The opening of the C-profile of the stiffening beam 6 is thus parallel to the opening of the C-profile of the profile beam 5.

Der Profilträger 5 und der Versteifungsträger 6 weisen jeweils an beiden Schmalseiten 7 fluchtend angeordnete Verbindungsöffnungen auf und die Verbindungseinrichtung 10, insbesondere bestehend aus einer Schraube und einer Mutter, greift durch alle vier Verbindungsöffnungen. Der Versteifungsträger 6 ist in Bezug auf den Profilträger 5 um 180° gedreht im Profil des Profilträgers 5 angeordnet, wobei der Versteifungsträger 6 die Öffnung des Profilträgers 5 durch eine Wandfläche abdeckt. 8 shows an example of a stiffening beam 6 with a C-profile, which is arranged in the U-profile of a profile beam 5. The profiled beam 5 and the stiffening beam 6 each have connecting openings arranged in alignment on both narrow sides 7 and the connecting device 10, consisting in particular of a screw and a nut, engages through all four connecting openings. The stiffening beam 6 is arranged rotated by 180° in relation to the profile beam 5 in the profile of the profile beam 5, with the stiffening beam 6 covering the opening of the profile beam 5 by a wall surface.

In Fig. 9 sind ein Profilträger 5 und ein Versteifungsträger 6 mit jeweils einem U-Profil beispielhaft abgebildet, wobei das Profil des Versteifungsträgers 6 formschlüssig und parallel zur Ausrichtung des Profilträgers 5 in demselben angeordnet ist. Die Öffnung des U-Profils des Versteifungsträgers 6 ist somit parallel zur Öffnung des U-Profils des Profilträgers 5. Der Profilträger 5 und der Versteifungsträger 6 weisen jeweils an einer ihrer Schmalseiten 7 fluchtend angeordnete Verbindungsöffnungen auf und die Verbindungseinrichtung 10, insbesondere bestehend aus einer Schraube und einer Mutter, greift durch die fluchtend angeordneten Verbindungsöffnungen der Träger 5, 6. Die Mutter ist innerhalb der Profile beider Träger 5, 6 verschraubt.In 9 a profiled beam 5 and a stiffening beam 6 are shown by way of example, each with a U-profile, the profile of the stiffening beam 6 being arranged in the same in a form-fitting manner and parallel to the alignment of the profiled beam 5 . The opening of the U-profile of the stiffening beam 6 is thus parallel to the opening of the U-profile of the profile beam 5. The profile beam 5 and the stiffening beam 6 each have on one of their narrow sides 7 aligned connecting openings and the connecting device 10, in particular consisting of a screw and a nut, engages through the aligned connection openings of the supports 5, 6. The nut is screwed inside the profiles of both supports 5, 6.

Fig. 10 zeigt beispielhaft einen Versteifungsträger 6 mit einem C-Profil, der in dem C-Profil eines Profilträgers 5 angeordnet ist. Der Profilträger 5 und der Versteifungsträger 6 weisen jeweils an beiden Schmalseiten 7 fluchtend angeordnete Verbindungsöffnungen auf. Der Versteifungsträger 6 ist in Bezug auf den Profilträger 5 um 180° gedreht im Profil des Profilträgers 5 angeordnet, wobei der Versteifungsträger 6 die Öffnung des Profils des Profilträgers 5 durch eine Wandfläche abdeckt. Durch die gegengleiche Anordnung der offenen Profile der Träger 5, 6 kann ein besonders geradliniges und verwindungsarmes Verbiegen der Träger 5, 6, insbesondere des Profilträgers 5, bei einem Anprallereignis erreicht werden. Der Profilträger 5 und der Versteifungsträger 6 weisen jeweils an einer ihrer Schmalseiten 7 fluchtend angeordnete Verbindungsöffnungen auf und die Verbindungseinrichtung 10, insbesondere bestehend aus einer Schraube und einer Mutter, greift durch die fluchtend angeordneten Verbindungsöffnungen der Träger 5, 6. 10 shows an example of a stiffening beam 6 with a C-profile, which is arranged in the C-profile of a profile beam 5. The profiled beam 5 and the stiffening beam 6 each have connecting openings arranged in alignment on both narrow sides 7 . The stiffening beam 6 is arranged rotated by 180° in relation to the profile beam 5 in the profile of the profile beam 5, with the stiffening beam 6 covering the opening of the profile of the profile beam 5 by a wall surface. Due to the opposite arrangement of the open profiles of the supports 5, 6, a particularly straight and low-torsion bending of the supports 5, 6, in particular of the profile support 5, can be achieved in the event of an impact. The profile beam 5 and the stiffening beam 6 each have on one of their narrow sides 7 aligned connecting openings and the Connecting device 10, consisting in particular of a screw and a nut, engages through the aligned connecting openings of the supports 5, 6.

Besonders bevorzugt kann vorgesehen sein, dass der Versteifungsträger 6 eine geringere Stahlgüte als der Profilträger 5 aufweist, wodurch Kosten gespart werden können. Beispielsweise kann vorgesehen sein, dass der Werkstoff des Versteifungsträgers 6 eine geringere Dehngrenze und/oder Zugfestigkeit als jener Werkstoff des Profilträgers 5 aufweist.Provision can particularly preferably be made for the stiffening beam 6 to have a lower steel grade than the profiled beam 5, as a result of which costs can be saved. For example, it can be provided that the material of the reinforcement beam 6 has a lower yield point and/or tensile strength than the material of the profile beam 5 .
