Abstract

The structure has a supporting element (116) arranged between a set of profiled posts (112) and a continuous guard-rail line (114). An intermediate element (120) is arranged between the supporting element and the guard-rail line and designed such that the guard-rail line runs at an inclination angle to a longitudinal axis (L) of the posts. The supporting element is designed asymmetrically for adaptation to the angle between the guard-rail line and the axis and comprises limbs (122, 124) that project from a fastening portion (118) in direction of the guard-rail line.

Description

Die vorliegende Erfindung betrifft eine Schutzplankenkonstruktion gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a protective barrier construction according to the preamble of patent claim 1.

Derartige Konstruktionen sind aus dem Stand der Technik hinlänglich bekannt und beispielsweise in DE 20 2006 010 573 U1 offenbart. Die in diesem Dokument offenbarte Schutzplankenanordnung besteht aus einem Schutzplankenstrang aus vorzugsweise lösbar aneinandergesetzten Schutzplanken und den Schutzplankenstrang tragenden im Querschnitt sigmaförmigen Pfosten, die in einen Untergrund getrieben werden. Die Befestigung der Schutzplanken an dem Pfosten erfolgt unter Zwischenschaltung von U-förmigen Stützbügeln.Such constructions are well known in the art and, for example, in DE 20 2006 010 573 U1 disclosed. The guard rail arrangement disclosed in this document consists of a protective barrier string of preferably demarcated protective barriers and the protective barrier string carrying in cross-section sigmoidal posts, which are driven into a subsoil. The attachment of the guard rails to the post is done with the interposition of U-shaped support brackets.

Fig. 1 beschreibt das Verhalten einer derartigen aus dem Stand der Technik bekannten Schutzplankenanordnung im Fall eines Anpralls eines Kraftfahrzeugs. Bei einem Fahrzeuganprall werden zuerst die in den Boden U gerammten Pfosten 12 deformiert und von der Fahrbahn weg gebogen. Bei einer höheren Belastung löst sich der Schutzplankenstrang 14 von dem Pfosten 12, d.h. nachdem eine Verbindungsschraube zur Befestigung des Schutzplankenstrangs 14 an dem Pfosten 12 an einer Sollbruchstelle gebrochen ist. Durch die Sollbruchstelle kann sich der Schutzplankenstrang 14 getrennt von den Pfosten 12 deformieren, die weiter in Richtung des Untergrunds U gebogen werden. Der Schutzplankenstrang 14 wird weiter deformiert und kann mit Hilfe seiner Zugbandwirkung ein Fahrzeug umlenken. Fig. 1 describes the behavior of such known from the prior art guard rail assembly in the event of an impact of a motor vehicle. In a vehicle collision, first the pillars 12 rammed into the ground U are deformed and bent away from the roadway. At a higher load, the protective barrier 14 dissolves from the post 12, ie after a connecting screw for fixing the guard rail 14 is broken at the post 12 at a predetermined breaking point. Due to the predetermined breaking point, the protective barrier strand 14 can deform separately from the posts 12, which are bent further in the direction of the underground U. The protective barrier 14 is further deformed and can deflect a vehicle by means of its Zugbandwirkung.

Es kann jedoch bei einer derartigen Schutrplankenkonstruktion nicht verhindert werden, dass sich der Schutzplankenstrang 14 absenkt, was gerade bei größeren Fahrzeugen dazu führen kann, dass der Schutzplankenstrang 14 überfahren wird. Mit anderen Worten "durchbricht" oder "überwindet" das Fahrzeug die Schutzplankenanordnung 10, wodurch es zu schwerwiegenden Unfällen und Personenschäden kommen kann.However, it can not be prevented in such a Schutrplankenkonstruktion that the protective barrier 14 lowers, which may lead just in larger vehicles that the protective barrier 14 is run over. In other words, the vehicle "breaks" or "overcomes" the guardrail assembly 10, which can result in serious accidents and personal injury.

Die NL 6 612 923 A offenbart eine leitplankenkonstruktion, bei der an einem Pfosten Zwischenstücke angeschraubt sind, die einen Parallelogramm-Querschnitt aufweisen. Obere und untere Schenkel der Zwischenstücke erstrecken sich schräg in Richtung eines an dem Zwischenstück befestigten Holms. Das Zwischenstück besteht aus einem schiefwinklig O-förmig gebogenen Blechstreifen, wobei zwischen dessen beiden Schenkeln ein Steg eingeschweißt ist, an dem der Holm befestigt ist. Der Steg erstreckt sich parallel zu dem Holm.The NL 6 612 923 A discloses a guard rail construction in which are bolted to a post intermediate pieces, which have a parallelogram cross-section. Upper and lower legs of the intermediate pieces extend obliquely in the direction of a spar attached to the intermediate piece. The intermediate piece consists of an obliquely angled O-shaped sheet metal strip, wherein between the two legs of a web is welded, to which the spar is attached. The bridge extends parallel to the spar.

Die EP 2 088 246 A2 offenbart eine Schutzplankenkonstruktion, bei der an einem Pfosten ein Stützelement angeordnet ist, an dem wiederum der Schutzplankenstrang befestigt ist. Das Stützelement bzw. Distanzstück stellt einen Winkel des Schutzplankenstrangs zur Längsachse der Pfosten ein. Zwischen dem Schutzplankenstrang und dem Distanzstück ist ein Arm angeordnet, der sich ausgehend von dem Distanzstück in Richtung des Untergrundes erstreckt. An dem Arm kann unterhalb des Schutzplankenstrangs ein weiterer Schutzplankenstrang befestigt werden.The EP 2 088 246 A2 discloses a guard rail construction in which a support member is disposed on a post to which in turn the guard rail is attached. The support member or spacer adjusts an angle of the guardrail strand to the longitudinal axis of the posts. Between the protective barrier strand and the spacer, an arm is arranged, which extends starting from the spacer in the direction of the substrate. On the arm, another guard rail can be attached below the guard rail.

Die DE 12 76 678 A offenbart eine Leitplanke, die an Pfosten befestigte Holme aufweist. Zwischen den Holmen und dem Pfosten sind Zwischenstücke vorgesehen, die an dem Pfosten befestigt sind. Ein unterer Schenkel des Zwischenstücks ist dünnwandiger ausgebildet als ein Oberschenkel. Die Länge des unteren Schenkels wird kleiner gewählt als die Länge des oberen Schenkels, so dass der an dem Zwischenstück befestigte Holm in einem Winkel zur lotrechten Ebene verläuft. Durch die Schrägstellung des Holms wird eine nach unten gerichtete Abweiskomponente erreicht, die das Überspringen des Fahrzeugs über die Leitplanke verhindern soll.The DE 12 76 678 A discloses a guardrail having posts attached to spars. Between the spars and the post intermediate pieces are provided, which are attached to the post. A lower leg of the intermediate piece is formed thinner than a thigh. The length of the lower leg is chosen smaller than the length of the upper leg, so that the spar attached to the intermediate piece extends at an angle to the vertical plane. Due to the inclination of the spar, a downward deflection component is achieved, which is intended to prevent the vehicle from skipping over the guardrail.

Die EP 1 627 956 A1 wird als nächstliegender Stand der Technik angesehen und offenbart eine Leitschwellenanordnung, bei der sich ein Leitplankenstrang über Stützholme an dem Pfosten abstützt. Zwischen den Stützholmen und dem Leitplankenstrang sind Distanzstücke vorgesehen.The EP 1 627 956 A1 is considered as the closest prior art and discloses a Leitschwellenanordnung in which a guardrail strand supported on support posts on the post. Spacers are provided between the support bars and the guard rail.

Es ist eine Aufgabe der vorliegenden Erfindung, eine Schutzplankenkonstruktion der eingangs bezeichneten Art bereitzustellen, die ein verbessertes Deformationsverhalten bei einem Fahrzeuganprall und somit ein größeres Aufhaltevermögen aufweist.It is an object of the present invention to provide a guardrail structure of the type referred to, which has an improved deformation behavior in a vehicle impact and thus a greater retention capacity.

Diese Aufgabe wird durch eine Schutzplankenkonstruktion mit den Merkmalen des Patentanspruchs 1 gelöst.This object is achieved by a protective barrier construction having the features of patent claim 1.

Durch die Kombination eines asymmetrischen Stützelements mit einem Zwischenelement, das derart ausgebildet ist, dass der Schutzplankenstrang in einem Winkel zur Längsachse der Profilpfosten verläuft, kann das Deformationsverhalten der Schutzplankenkonstruktion erheblich verbessert werden, insbesondere wird das Absinken des Schutzplankenstrangs bei fortschreitender Deformierung der Schutzplankenkonstruktion verhindert. Somit kann sich auch ein schweres anprallendes Fahrzeug noch an dem Schutzplankenstrang abstützen und umgelenkt werden. Die Neigung des Schutzplankenstrangs in Richtung des Untergrunds wird durch das Stützelement unterstützt, das durch seinen asymmetrischen Aufbau und sein Deformationsverhalten den Neigungswinkel des Schutzplankenstrangs sogar vergrößern kann und somit wesentlich dazu beiträgt, dass der Schutzplankenstrang in einer erhöhten Position verbleibt und nicht von einem anprallenden Fahrzeug überfahren werden kann.By combining an asymmetric support element with an intermediate element, which is designed such that the protective barrier strand runs at an angle to the longitudinal axis of the profile posts, the deformation behavior of Guard rail construction can be significantly improved, in particular, the lowering of the guard rail is prevented with progressive deformation of the guard rail construction. Thus, even a heavy impacting vehicle can still be supported on the guard rail and deflected. The inclination of the protective barrier strand in the direction of the ground is supported by the support element, which can even increase the angle of inclination of the protective barrier by its asymmetric structure and its deformation behavior and thus contributes significantly to the fact that the protective barrier strand remains in an elevated position and not run over by an impacting vehicle can be.

Durch den Neigungswinkel wird nicht nur ein Absinken verhindert, sondern der Schutzplankenstrang wird bei fortschreitender Deformation aufgrund des Neigungswinkels in eine erhöhte Position verlagert. Dazu weist das Stützelement seine asymmetrische Gestalt auf, bei der obere in Richtung des Schutzplankenstrangs vorspringende Schenkel des Stützelements relativ steif ausgelegt ist und sich erst mit einer Verzögerung deformiert, wodurch der Neigungswinkel des Schutzplankenstrangs in Richtung des Untergrunds vergrößert wird und ein Absinken des Schutzplankenstrangs auch bei größeren auftretenden Anprallkräften unterbunden wird. Mit anderen Worten verbleibt der Schutzplankenstrang auch nach dem Lösen von dem Profilposten - verglichen mit dem Stand der Technik (Fig.1) - in einer erhöhten Position bzw. wird durch den Neigungswinkel zu dem Untergrund und das anprallende Fahrzeug weiter angehoben, wodurch sich relativ große Fahrzeuge an dem Schutzplankenstrang anlegen können und durch diesen umgelenkt werden.Due to the inclination angle not only a drop is prevented, but the protective barrier strand is displaced as the deformation progresses due to the inclination angle in an elevated position. For this purpose, the support element has its asymmetrical shape, is designed to be relatively stiff in the upper protruding in the direction of the protective barrier leg of the support element and deformed only with a delay, whereby the inclination angle of the protective barrier in the direction of the substrate is increased and a lowering of the protective barrier strand even at larger occurring impact forces is prevented. In other words, the protective barrier strand remains even after release from the profile post - compared with the prior art ( Fig.1 ) - in an elevated position or by the angle of inclination to the ground and the impacting Vehicle further raised, which can create relatively large vehicles on the protective barrier and are deflected by this.

Eine Weiterbildung der Erfindung sieht vor, dass der wenigstens eine Schenkel des Stützelements einen vorbestimmten Winkel zur Mittelachse der Profilpfosten aufweist. Durch den Winkel der Schenkel des Stützelements zur Längsachse der Profilpfosten kann das Deformationsverhalten des Stützelements beeinflusst werden, d.h. der zeitliche Ablauf einer Deformation des Stützelements wird festgelegt. Dies ist insbesondere für den kontrollierten Ablauf der Deformation bei einem Fahrzeuganprall von großer Bedeutung.A development of the invention provides that the at least one leg of the support element has a predetermined angle to the central axis of the profile posts. The angle of the legs of the support element to the longitudinal axis of the profile posts, the deformation behavior of the support element can be influenced, i. the timing of a deformation of the support element is determined. This is particularly important for the controlled course of deformation in a vehicle crash of great importance.

Das Stützelement weist gemäß einer bevorzugten Ausführungsform der Erfindung zwei von dem Befestigungsabschnitt vorspringende Schenkel auf, die sich jeweils in einem Winkel zur Längsachse der Profilpfosten erstrecken, wobei sich die Winkel der vorspringenden Schenkel zu dem Befestigungsabschnitt unterscheiden. Um bei einem Fahrzeuganprall eine Absenkung des Schutzplankenstrangs zu vermeiden bzw. eine Verlagerung des Schutzplankenstrangs nach oben weg von dem Untergrund bei fortschreitender Deformation zu erreichen, werden erfindungsgemäß die beiden Winkel zwischen den Schenkeln des Stützelements und dem Befestigungsabschnitt derart ausgelegt, dass sich der dem Untergrund nähere Schenkel des Stützelements zuerst deformiert, wodurch der Neigungswinkel des Schutzplankenstrangs zur Längsachse der Profilpfosten zumindest beibehalten wird.The support member according to a preferred embodiment of the invention comprises two legs projecting from the attachment portion, each extending at an angle to the longitudinal axis of the profile posts, the angles of the projecting legs differing from the attachment portion. In order to avoid a lowering of the protective barrier strand in a vehicle collision or to achieve a displacement of the protective barrier upwards away from the ground as the deformation progresses, the two angles between the legs of the support element and the fixing section are designed according to the invention such that it approaches the ground Leg of the support element first deformed, whereby the angle of inclination of the guard rail to the longitudinal axis of the profile posts is at least maintained.

Aus diesem Grund sieht eine bevorzugte Ausführungsform der Erfindung vor, dass der dem Untergrund nähere Schenkel des Stützelements einen größeren Winkel zur Längsachse der Profilpfosten aufweist, als der Winkel zwischen dem jeweils anderen Schenkel und der Längsachse der Profilpfosten. So wird sichergestellt, dass sich bei einem Fahrzeuganprall zuerst der untere Schenkel deformiert und die Neigung des Schutzplankenstrangs erhöht wird. Dadurch wird die Verlagerung des Schutzplankenstrangs nach oben bei einem Fahrzeuganprall unterstützt und das Aufhaltevermögen der Schutzplankenkonstruktion erhöht bzw. die das Überfahren des Schutzplankenstrangs durch ein anprallendes Fahrzeug wirksam verhindert. Bei dem Stützelement der erfindungsgemäßen Schutzplankenkonstruktion wird der den größeren Winkel zur Längsachse der Profilpfosten aufweisende Schenkel aufgrund des größeren Hebelarms für ein anprallendes Fahrzeug zuerst verformt, wodurch die Neigung des Schutzplankenstrangs zur Längsachse der Profilpfosten vergrößert wird und der Schutzplankenstrang aufgrund des anprallenden Fahrzeugs in eine erhöhte Position verlagert wird.For this reason, a preferred embodiment of the invention provides that the closer to the ground leg of the support member has a greater angle to the longitudinal axis of the profile posts, as the angle between the respective other leg and the longitudinal axis of the profile posts. This ensures that, in the event of a vehicle collision, the lower leg first deforms and the inclination of the guardrail strand is increased. As a result, the displacement of the guardrail strand is supported upwards in a vehicle collision and increases the stoppage of the guard rail construction or effectively prevents the collision of the guardrail strand by an impacting vehicle. In the support element of the guard rail construction according to the invention, the leg having the greater angle to the longitudinal axis of the profile posts is first deformed due to the larger lever arm for an impacting vehicle, thereby increasing the inclination of the guard rail to the longitudinal axis of the profile posts and the protective barrier strand is elevated to a raised position due to the impacting vehicle is relocated.

In diesem Zusammenhang ist festzuhalten, dass gemäß einer Weiterbildung der Erfindung der Winkel zwischen dem dem Untergrund näheren Schenkel des Stützelements und der Längsachse der Profilpfosten ungleich 90° ist.In this context, it should be noted that, according to one embodiment of the invention, the angle between the leg closer to the ground of the support element and the longitudinal axis of the profile posts is not equal to 90 °.

Ferner kann das Deformationsverhalten der Schutzplankenkonstruktion und insbesondere des Stützelements dadurch beeinflusst werden, dass gemäß einer Weiterbildung der Erfindung die beiden von dem Befestigungsabschnitt vorspringenden Schenkel des Stützelements unterschiedlich lang sind.Furthermore, the deformation behavior of the guard rail construction and in particular of the support element can be influenced by the fact that, according to an embodiment of the invention, the two legs of the support element projecting from the attachment section have different lengths.

Erfindungsgemäß ist das Zwischenelement derart ausgelegt, dass es sich mit einer Fläche an den Befestigungsabschnitt des Stützelements anlegt und die dieser Fläche gegenüberliegende Fläche abgeschrägt ist. Mit anderen Worten weist das Zwischenelement eine Keilform auf, die den Winkel des Schutzplankenstrangs zur Längsachse der Profilpfosten festlegt.According to the invention, the intermediate element is designed such that it rests with a surface on the attachment portion of the support member and the surface opposite this surface is chamfered. In other words, the intermediate element has a wedge shape, which defines the angle of the protective barrier strand to the longitudinal axis of the profile posts.

Die erfindungsgemäße Schutzplankenkonstruktion kann auch auf einem Streifenfundament, einer Brücke oder ähnlichen Bauwerken verwendet werden, wobei die Pfosten hier sehr viel starrer mit dem Untergrund, zumeist aus Beton, verbunden sind. Beispielsweise werden die Pfosten mit dem Untergrund verschraubt. Um den Anprall eines Fahrzeugs für die Insassen aufgrund der starren Verbindung zum Untergrund nicht zu hart werden zu lassen, d.h. einen möglichst großen Anteil der Anprallenergie über die Schutzplankenkonstruktion aufzunehmen, kann gemäß einer bevorzugten Ausführungsform der Erfindung zwischen dem Profilpfosten und dem Stützelement ein Deformationselement vorgesehen sein. So wird durch das Deformationselement bereits ein erheblicher Teil der Anprallenergie abgebaut, bevor das Fahrzeug überhaupt mit den starren Pfosten in Berührung kommt. Mit anderen Worten wird das Anschlagen des Fahrzeugs über die Deformationszeit des Deformationselements zeitlich gestreckt, wodurch die Verzögerung und somit die Belastung für die Insassen erheblich verringert werden kann.The guard rail construction according to the invention can also be used on a strip foundation, a bridge or similar structures, wherein the posts are much more rigidly connected to the ground, mostly made of concrete. For example, the posts are bolted to the ground. In order not to let the impact of a vehicle on the occupants due to the rigid connection to the ground be too hard, i. To absorb the largest possible proportion of the impact energy on the guard rail construction, according to a preferred embodiment of the invention between the profile post and the support member may be provided a deformation element. Thus, a considerable part of the impact energy is already dissipated by the deformation element before the vehicle ever comes into contact with the rigid posts. In other words, the impact of the vehicle on the deformation time of the deformation element is extended in time, whereby the delay and thus the load on the occupants can be significantly reduced.

Gemäß einer bevorzugten Ausführungsform legt sich das Stützelement mit seinem parallel zur Mittelachse der Profilpfosten erstreckenden Abschnitt an das Deformationselement oder den Profilpfosten an.According to a preferred embodiment, the support element engages with its parallel to the central axis of the profile post extending portion of the deformation element or the profile post.

Vorzugsweise liegt der Winkel zwischen dem Schutzplankenstrang und der Längsachse der Profilpfosten zwischen 1 und 10°.Preferably, the angle between the protective barrier strand and the longitudinal axis of the profile posts is between 1 and 10 °.

Gemäß einer Weiterbildung der Erfindung sind an den Profilpfosten zwei im Wesentlichen parallel verlaufende Schutzplankenstränge angeordnet, die jeweils über ein Stützelement und ein Zwischenelement mit den Profilpfosten in Verbindung stehen und jeweils in einem Winkel zur Längsachse der Profilpfosten verlaufen.According to one embodiment of the invention, two substantially parallel protective barrier strands are arranged on the profile post, which are in each case via a support member and an intermediate element with the profile post in connection and extend at an angle to the longitudinal axis of the profile posts.

Fig. 2 zeigt eine perspektivische Explosionsdarstellung der erfindungsgemäßen Schutzplankenkonstruktion, die allgemein mit 100 bezeichnet ist. Fig. 2 shows an exploded perspective view of the guard rail construction according to the invention, which is generally designated 100.

Aus Fig. 2 erkennt man die Profilpfosten 112, die in einen hier nicht gezeigten Untergrund zur Befestigung der Schutzplankenkonstruktion 100 gerammt werden. Neben den Profilpfosten 112 zeigt Fig. 2 den entlang einer Fahrbahn (nicht gezeigt) verlaufenden Schutzplankenstrang 114. Zwischen den Profilpfosten 112 und den Schutzplanken des Schutzplankenstrangs 114 sind Stützelemente 116 angeordnet. Die Stützelemente 116 legen sich direkt mit einem Befestigungsabschnitt 118 an die Profilpfosten 112 an, d.h. der Befestigungsabschnitt 118 der Stützelemente 116 erstreckt sich parallel zu einer Längsachse L der Profil pfosten 112. Durch die plane Anlage des Befestigungsabschnitt 118 an den Profilpfosten 112, kann sich das Stützelement 116 großflächig an den Profilposten 112 abstützen und einen relativ großen Anteil der Anprallkraft eines Fahrzeugs aufnehmen und so auf den Profilpfosten 112 übertragen. Die Stützelemente 116 weisen hier zwei von dem Befestigungsabschnitt 118 vorspringende Schenkel 122 und 124 auf, die den Schutzplankenstrang 114 abstützen.Out Fig. 2 one recognizes the profile posts 112, which are rammed into a substrate, not shown here for attachment of the guard rail construction 100. Next to the profile posts 112 shows Fig. 2 along a roadway (not shown) extending guard rail 114. Between the profile posts 112 and the protective barriers of the guard rail 114 support elements 116 are arranged. The support members 116 lie directly with a mounting portion 118 to the profile posts 112, ie, the mounting portion 118 of the support members 116 extends parallel to a longitudinal axis L of the profile post 112. By the planar contact of the mounting portion 118 to the profile post 112, the Support member 116 a large area on the profile post 112 and absorb a relatively large proportion of the impact force of a vehicle and so transferred to the profile post 112. The support members 116 here have two of the mounting portion 118 projecting legs 122 and 124 which support the protective barrier 114 strand.

Ferner sind aus Fig. 2 andeutungsweise die Zwischenelemente 120 ersichtlich, die derart ausgebildet sind, dass der Schutzplankenstrang 114 zur Längsachse L der Profilpfosten 112 geneigt verläuft. Die Zwischenelemente 120 werden im weiteren Verlauf dieser Beschreibung detailliert beschrieben. Die Zwischenelemente 120 können direkt an den Stützelementen 116 angeformt werden oder auch Einzelteile darstellen.Furthermore, are off Fig. 2 hint, the intermediate elements 120 can be seen, which are designed such that the protective barrier strand 114 to the longitudinal axis L of the profile posts 112 is inclined. The intermediate elements 120 will be described in detail later in this description. The intermediate elements 120 can be formed directly on the support members 116 or represent items.

Ferner zeigt Fig. 2, dass die Schutzplanken 114 und das Stützelement 116 über Schraubverbindungen an dem Profilpfosten 112 angebracht sind.Further shows Fig. 2 in that the guard rails 114 and the support element 116 are attached to the profile post 112 by screw connections.

Fig. 3 zeigt eine Seitenansicht der Schutzplankenkonstruktion 100. Man erkennt wiederum den Profilpfosten 112 und den Schutzplankenstrang 114 sowie das zwischen den Profilpfosten 112 und dem Schutzplankenstrang 114 angeordnete Stützelement 116. Das Stützelement 116 legt sich mit seinem parallel zu dem Profilpfosten 112 verlaufenden Befestigungsabschnitt 118 an den Profilpfosten 112 an. Das Zwischenelement 120 wiederum legt sich mit einer Fläche 120a an den Befestigungsabschnitt 118 des Stützelements 116 an und weist eine der Fläche 120 gegenüberliegende, abgeschrägte Fläche 120b auf, an die sich der Schutzplankenstrang 114 teilweise anlegt. Durch die Anlage des Schutzplankenstrangs 114 an die abgeschrägte Fläche 120b des Zwischenelements 120 verläuft der Schutzplankenstrang 114 abgewinkelt zu der Längsachse (hier nicht gezeigt) der Profilpfosten 112. Mit anderen Worten wird durch die abgeschrägte Fläche 120b des Zwischenelemente 120 der Neigungswinkel des Schutzplankenstrangs 114 zu der Längsachse L der Profilpfosten 112 eingestellt. Der Neigungswinkel des Schutzplankenstrangs 114 zur Längsachse L der Profil pfosten 112 kann auch durch die konstruktive Gestaltung des Stützelements 116 mit den Schenkeln 122 und 124 bzw. über die Länge der Schenkel 122 und 124 eingestellt werden. Fig. 3 shows a side view of the guard rail construction 100. It can be seen again the profile post 112 and the guard rail 114 and disposed between the profile post 112 and the guard rail 114 support member 116. The support member 116 lies down with its parallel to the profile post 112 extending mounting portion 118 to the profile post 112th at. The intermediate element 120 in turn abuts with a surface 120a on the mounting portion 118 of the support member 116 and has a surface 120 opposite, beveled surface 120b, to which the guard rail 114 partially applies. By the arrangement of the protective barrier strand 114 to the tapered surface 120 b of the intermediate member 120 of the guard rail 114 extends angled to the longitudinal axis (not shown here) of the profile post 112. In other words, by the tapered surface 120 b of the intermediate elements 120 of the inclination angle of the guard rail 114 to the Longitudinal axis L of the profile post 112 is set. The angle of inclination of the guard rail 114 to the longitudinal axis L of the profile post 112 can also be adjusted by the structural design of the support member 116 with the legs 122 and 124 and over the length of the legs 122 and 124.

Fig. 3 zeigt deutlich die asymmetrische Gestaltung des Stützelements 116, die notwendig ist, um das Stützelement 116 an den durch das Zwischenelement 120 festgelegten Winkel des Schutzplankenstrangs 114 zu der Längsachse L der Profilpfosten 112 anzupassen. Ein Winkel β des Schenkels 122 zu dem Profilpfosten 112 bzw. dessen Längsachse L ist kleiner als ein Winkel α zwischen der Längsachse L der Profilpfosten 112 und dem Schenkel 124, der dem Untergrund näher ist. Fig. 3 clearly shows the asymmetrical design of the support member 116, which is necessary to adjust the support member 116 at the angle defined by the intermediate member 120 angle of the protective barrier strand 114 to the longitudinal axis L of the profile posts 112. An angle β of the leg 122 to the profile post 112 or its longitudinal axis L is smaller than an angle α between the longitudinal axis L of the profile posts 112 and the leg 124, which is closer to the ground.

Durch eine derartige konstruktive Gestaltung der Stützelemente 116 kann das Deformationsverhalten der Schutzplankenkonstruktion 100 im Anprallfall eines Kraftfahrzeugs positiv beeinflusst werden, was im Folgenden dieser Beschreibung ausführlich beschrieben wird.By such a structural design of the support elements 116, the deformation behavior of the guard rail construction 100 can be positively influenced in the event of a collision of a motor vehicle, which will be described in detail in the following description.

Fig. 4a zeigt erneut eine Seitenansicht der Schutzplankenkonstruktion 100 mit einem ein B-Profil aufweisenden Schutzplankenstrang 114. Fig. 4a shows again a side view of the guard rail construction 100 with a B-profile having protective barrier 114th

Ferner zeigt Fig. 4b eine Einzelteildarstellung des Stützelements 116 mit dem daran angeordneten Zwischenelement 120 gemäß einem ersten Ausführungsbeispiel. Wie bereits erwähnt, ist das Zwischenelement 120 an dem Befestigungsabschnitt 118 des Stützelements 116 vorgesehen. Man erkennt ferner, dass der Winkel α des Schenkels 124 zu dem parallel zur Längsachse L der Profilpfosten 112 verlaufenden Befestigungsabschnitt 118 deutlich größer ist als der Winkel β des Schenkels 122 zu dem Befestigungsabschnitt 118. Dadurch wird erreicht, dass sich im Anprallfall eines Fahrzeugs zuerst der untere dem Untergrund nähere Schenkel 124 in Richtung des Profilpfostens 112 verformt. Durch die schnellere Verformung des unteren Schenkels 124 verglichen mit der Deformationszeit des oberen Schenkels 122 wird erreicht, dass der Schutzplankenstrang 114 im Anprallfall eines Fahrzeugs die Neigung zumindest beibehält und sich bei fortschreitender Deformation nach oben bewegt und auch ein schweres Fahrzeug oder ein Fahrzeug mit hoher Geschwindigkeit am Überfahren des Schutzplankenstrangs 114 gehindert werden kann. Anders ausgedrückt, hat die Kraft, die durch ein anprallendes Fahrzeug auf die Schutzplankenkonstruktion 100 ausgeübt wird, durch den größeren Winkel α des Schenkels 124 einen größeren Hebelarm von der Biegestelle, an der der Befestigungsabschnitt 118 in den Schenkel 124 übergeht, verglichen mit dem kleineren Winkel β des Schenkel 122, wodurch der Schenkel 124 deutlicher schneller deformiert wird, als der Schenkel 122.Further shows Fig. 4b an exploded view of the support member 116 with the intermediate member 120 disposed thereon according to a first embodiment. As already mentioned, the intermediate element 120 is provided on the attachment portion 118 of the support element 116. It can also be seen that the angle α of the leg 124 to the parallel to the longitudinal axis L of the profile posts 112 extending mounting portion 118 is significantly greater than the angle β of the leg 122 to the mounting portion 118. This ensures that deformed in the collision case of a vehicle, first lower leg closer to the ground 124 in the direction of the profile post 112. The faster deformation of the lower leg 124 compared to the deformation time of the upper leg 122 ensures that the crash barrier 114 at least retains the inclination in the event of a collision with a vehicle and moves upwards as the deformation progresses, and also a heavy vehicle or vehicle at high speed can be prevented from passing over the guard rail 114. In other words, the force exerted by an impacting vehicle on the guard rail construction 100 has, due to the larger angle α of the leg 124, a larger lever arm from the bend where the attachment portion 118 merges into the leg 124 compared to the smaller angle β of the leg 122, whereby the leg 124 is deformed much faster than the leg 122nd

Fig. 5a zeigt eine Seitenansicht der Schutzplankenkonstruktion 100 mit einem ein A-Profil aufweisenden Schutzplankenstrang 114 und Fig. 5b zeigt eine Einzelteildarstellung eines Stützelements 116 gemäß dem zweiten Ausführungsbeispiel. Fig. 5a shows a side view of the guard rail construction 100 with an A-profile guardrail 114 and Fig. 5b shows an exploded view of a support member 116 according to the second embodiment.

Wie man aus vergleichender Ansicht der Figuren 5a und 5b erkennt, verläuft bei dem Stützelement 116 gemäß diesem Ausführungsbeispiel der untere Schenkel 124 in einem Winkel α zu dem Befestigungsabschnitt 118, wohingegen der oberen Schenkel 122 senkrecht (Winkel β) zu dem Befestigungsabschnitt 118 verläuft. Um jedoch die voranstehend bereits beschriebene schnellere Deformation des unteren Schenkels 124 beizubehalten, weist dieser einen Winkel α von ungleich 90° zu dem Befestigungsabschnitt 118 des Stützelements 116 auf. Aus Fig. 5a wird zudem ersichtlich, dass das Zwischenelement 120 gemäß diesem Ausführungsbeispiel aufgrund des mit A-Profil ausgebildeten Schutzplankenstrangs 114 dicker ausgebildet werden muss.As you can see from the comparative view of FIGS. 5a and 5b detects, runs at the support member 116 according to this embodiment, the lower leg 124 at an angle α to the mounting portion 118, whereas the upper leg 122 perpendicular (angle β) to the mounting portion 118 extends. However, in order to maintain the earlier described faster deformation of the lower leg 124, this has an angle α of not equal to 90 ° to the mounting portion 118 of the support member 116. Out Fig. 5a In addition, it can be seen that the intermediate element 120 according to this exemplary embodiment has to be made thicker due to the guard rail strand 114 formed with the A-profile.

Fig. 6 zeigt eine perspektivische Ansicht und eine Seitenansicht des Stützelements 116 gemäß dem ersten Ausführungsbeispiel. Man erkennt erneut die beiden Schenkel 122 und 124, die jeweils einen anderen Winkel α,β zu dem Befestigungsabschnitt 118 aufweisen. Ferner erkennt man aus Fig. 6, dass der untere Schenkel 124 verglichen mit dem oberen Schenkel 122 verkürzt ausgebildet ist. Fig. 6 shows a perspective view and a side view of the support member 116 according to the first embodiment. It can be seen again the two legs 122 and 124, each having a different angle α, β to the mounting portion 118. Furthermore, one recognizes Fig. 6 in that the lower leg 124 is shortened compared to the upper leg 122.

Fig. 7 zeigt ein auf das Stützelement 116 gemäß dem ersten Ausführungsbeispiel abgestimmtes Zwischenelement 120. Das Zwischenelement 120 ist keilförmig ausgebildet und weist dazu eine vertikal verlaufende Fläche 120a auf, die sich an den Befestigungsabschnitt 118 des Stützelements 116 anlegen kann. Die zu der Fläche 120a gegenüberliegende Fläche 120b des Zwischenelements 120 verläuft abgeschrägt zur Fläche 120a, um den Neigungswinkel des Schutzplankenstrangs 114 (Fig. 1 bis 3) zur Längsachse der Profilpfosten 112 einzustellen. Fig. 7 shows an adapted to the support member 116 according to the first embodiment intermediate member 120. The intermediate member 120 is wedge-shaped and has for this purpose a vertically extending surface 120a, which is adjacent to the mounting portion 118 of the support member 116 can create. The surface 120b of the intermediate element 120 lying opposite the surface 120a is bevelled to the surface 120a in order to reduce the angle of inclination of the protective barrier strand 114 (FIG. Fig. 1 to 3 ) to the longitudinal axis of the profile posts 112.

Fig. 8 zeigt ein Stützelement 116 gemäß dem zweiten Ausführungsbeispiel und Fig. 9 zeigt verschiedene Ansichten eines auf das Stützelement 116 gemäß dem zweiten Ausführungsbeispiel abgestimmten Zwischenelements 120. Fig. 8 shows a support member 116 according to the second embodiment and Fig. 9 shows various views of an adapted to the support member 116 according to the second embodiment intermediate member 120th

Wie bereits voranstehend beschrieben ist das Zwischenelement 120 zur Anpassung an das A-Profil des Schutzplankenstrangs 114 verglichen mit dem voranstehend beschriebenen Ausführungsbeispiel verbreitert ausgebildet. Aufgrund der Unterschiede zwischen A- und B-Profil muss das keilförmige Zwischenelement 120 verbreitert ausgebildet werden, d.h. der Abstand zwischen den Flächen 120a und 120b ist größer als bei dem mit Bezug auf die Figur 7 beschriebenen Ausführungsbeispiel, da das A-Profil des Schutzplankenstrangs 114 bei der schrägen Anbringung durch das Zwischenelement 120 mit einem Ende an dem Pfosten 112 anliegen würde. Eine derartige Anlage könnte das Deformationsverhalten der Schutzplankenanordnung 100 bzw. des Stützelements 116 negativ beeinflussen.As already described above, the intermediate element 120 is designed widened to adapt to the A-profile of the protective barrier strand 114 compared to the embodiment described above. Due to the differences between the A and B profiles, the wedge-shaped intermediate member 120 must be made widened, that is, the distance between the surfaces 120a and 120b is larger than that with respect to FIG FIG. 7 described embodiment, since the A-profile of the protective barrier strand 114 would abut at the oblique attachment by the intermediate member 120 with one end to the post 112. Such a system could adversely affect the deformation behavior of the guard rail assembly 100 and the support member 116, respectively.

Die Fig. 10a und 10b zeigen ein drittes Ausführungsbeispiel des Stützelements 116. Das Stützelement 116 weist nur einen Schenkel 122 auf, der sich in Abhängigkeit von dem Profil des Schutzplankenstrangs 114 (A-Profil oder B-Profil) in einem vorbestimmten Winkel zu dem Befestigungsabschnitt 118 des Stützelements 116 erstreckt.The 10a and 10b show a third embodiment of the support member 116. The support member 116 has only one leg 122 which extends in dependence on the profile of the guard rail 114 (A-profile or B-profile) at a predetermined angle to the mounting portion 118 of the support member 116.

In Fig. 10a weist der Schutzplankenstrang 114 ein B-Profil auf und der Schenkel 122 springt einem vorbestimmten Winkel β von ungleich 90 Grad in Richtung des Befestigungsabschnitts 118 vor.In Fig. 10a the guard rail 114 has a B-profile and the leg 122 protrudes at a predetermined angle β of not equal to 90 degrees in the direction of the mounting portion 118.

Fig. 10b zeigt einen Schutzplankenstrang mit A-Profil. Der Schenkel 122 des Stützelements 116 erstreckt sich zur Anpassung an das A-Profil des Schutzplankenstrangs 114 senkrecht (Winkel β) zu dem Befestigungsabschnitt 118, wodurch der Schenkel 122 sehr steif ist und erst bei einer relativ großen Krafteinwirkung deformiert wird. Fig. 10b shows a protective barrier with A-profile. The leg 122 of the support member 116 extends perpendicularly (angle β) to the mounting portion 118 to conform to the A-profile of the guardrail strand 114, whereby the leg 122 is very stiff and is deformed only at a relatively large force.

Die Funktionsweise einer Schutzplankenkonstruktion 100 mit dem Stützelement 116 mit nur einem Schenkel 122 ist der Funktionsweise eines Stützelements 116 mit zwei Schenkeln 122 und 124 sehr ähnlich. Bei einem Stützelement 116 mit nur einem Schenkel 122 wird der Schutzplankenstrang 114 ohne Deformation eines zweiten Schenkels des Stützelements 116 sofort in Richtung des Profil pfostens 112 verlagert. Durch diese Deformation des Schutzplankenstrangs 114 in Richtung des Profilpfostens 112 wird der Neigungswinkel des Schutzplankenstrangs 114 vergrößert, was zur Erhöhung des Schutzplankenstrangs 114 während einer Deformation durch ein anprallendes Fahrzeug beiträgt und die Kraftaufnahmefähigkeit der Schutzplankenkonstruktion 100 erhöht.The operation of a protective barrier construction 100 with the support element 116 with only one leg 122 is very similar to the operation of a support element 116 with two legs 122 and 124. In a support member 116 with only one leg 122 of the guard rail 114 is without deformation of a second Leg of the support member 116 immediately post in the direction of the profile 112 moves. This deformation of guard rail 114 toward profile post 112 increases the angle of inclination of guard rail 114, which contributes to the increase of guard rail 114 during deformation by an impacting vehicle and increases the force absorbing capability of guard rail construction 100

Fig. 11 zeigt die Wirkungsweise der Schutzplankenkonstruktion 100 bei einem Anprall eines Kraftfahrzeugs. Die gepunkteten Linien stellen jeweils die Grundstellung der Schutzplankenanordnung 100 dar. Zuerst wird bei einem Anprall der untere Schenkel 124 des Stützelements 116 in Richtung des Profilpfostens 112 deformiert und der Schutzplankenstrang 114 neigt sich etwas mehr in Richtung des Untergrunds. Anschließend wird der Profilpfosten 112 aufgrund der Anprallkraft des Kraftfahrzeugs von einer Fahrbahn (nicht gezeigt) wegbogen. Das Stützelement 116 und der Schutzplankenstrang 114 lösen sich von dem Profilpfosten 112 ab, nachdem eine Verbindungsschraube (nicht gezeigt) an einer Sollbruchstelle gebrochen ist. Man erkennt aus Figur 9, dass auch bei der fortschreitenden Deformation des Schutzplankenstrangs 114 dieser immer in Richtung des Untergrunds U geneigt bleibt und gleichzeitig seine Höhe relativ zu dem Untergrund U beibehält. Verbiegt sich der Profilpfosten 112 weiter in Richtung des Untergrunds, d.h. das Fahrzeug wird bereits durch die Zugbandwirkung des Schutzplankenstrangs 114 abgelenkt, wird der Schutzplankenstrang 114 aufgrund seiner Neigung in eine erhöhte Position verlagert, wodurch das Fahrzeug sicher abgelenkt werden kann. Durch ein derartiges Anprallverhalten können auch größere Fahrzeuge bzw. schnellere Fahrzeuge aufgehalten bzw. abgelenkt werden, und ein Überfahren der Schutzplankenkonstruktion 100 wird wirksam verhindert . Fig. 11 shows the operation of the guard rail construction 100 in an impact of a motor vehicle. The dotted lines each represent the basic position of the guard rail assembly 100. First, in an impact, the lower leg 124 of the support member 116 is deformed in the direction of the profile post 112 and the guard rail 114 tilts slightly more towards the ground. Subsequently, the profile post 112 is due to the impact force of the motor vehicle of a roadway (not shown) wegbogen. The support member 116 and the guard rail 114 detach from the profile post 112 after a connecting bolt (not shown) is broken at a predetermined breaking point. One recognizes FIG. 9 in that, even with the progressive deformation of the guard rail 114, it always remains inclined in the direction of the ground U and at the same time maintains its height relative to the ground U. Bends the profile post 112 further in the direction of the ground, ie the vehicle is already deflected by the Zugbandwirkung the guard rail 114, the guard rail 114 is displaced due to its inclination in an elevated position, whereby the vehicle can be deflected safely. By such an impact behavior and larger vehicles or faster vehicles can be stopped or distracted, and overrunning the guard rail construction 100 is effectively prevented.

Fig. 12 zeigt Seitenansichten der Schutzplankenkonstruktion 100 bei einem Fahrzeuganprall, aus denen die schnelle Deformation des unteren Schenkels 124 und die Vergrößerung der Neigungswinkels ersichtlich wird. Aus diesen Ansichten erkennt man deutlich, wie der untere Schenkel 124 des Stützelements 116 in Richtung des Profilpfostens 112 deformiert wird und sich schließlich an den Profilpfosten 112 anlegt, wodurch sich der Neigungswinkel des Schutzplankenstrangs 114 zu dem Profilpfosten 112 vergrößert. Wie voranstehend bereits beschrieben, führt dies zu einem verbesserten Deformationsverhalten der gesamten Schutzplankenkonstruktion 100, wodurch größere Fahrzeuge oder Fahrzeuge mit einer höheren Geschwindigkeit mit der Schutzplankenkonstruktion 100 aufgehalten und abgelenkt werden können. Fig. 12 shows side views of the guard rail construction 100 in a vehicle collision, from which the rapid deformation of the lower leg 124 and the increase in the inclination angle is apparent. From these views it can be seen clearly how the lower leg 124 of the support member 116 is deformed in the direction of the profile post 112 and finally rests against the profile post 112, whereby the inclination angle of the guard rail 114 to the profile post 112 increases. As previously described, this results in an improved deformation behavior of the entire guard rail construction 100, whereby larger vehicles or vehicles can be stopped and deflected at a higher speed with the guard rail construction 100.

Fig. 13 zeigt eine Seitenansicht eines Stützelements 116 mit dem Zwischenelement 120 und einem an dem Stützelement 116 angebrachten Deformationselement 126. Das Stützelement 116 kann auch einstückig mit dem Deformationselement 126 ausgebildet werden. Fig. 13 shows a side view of a support member 116 with the intermediate member 120 and a mounted on the support member 116 deformation element 126. The support member 116 may also be integrally formed with the deformation element 126.

Die Fig. 14a bis 14c zeigen verschiedene Ansichten einer Schutzplankenkonstruktion 200, die beispielsweise auf einer Brücke angebracht ist. Die Profilpfosten 212 werden hier über Schrauben 228 mit dem Untergrund (hier nicht gezeigt) verschraubt. Ebenso wird das Deformationselement 226 mit dem daran angebrachten Stützelement 216 sowohl mit dem Profilpfosten 212 als auch mit dem Schutzplankenstrang 214 verschraubt. Man erkennt ferner aus den Figuren 14a und 14c, dass sich die Profilpfosten 212 vertikal deutlich weiter nach oben erstrecken und an dem oberen Ende der Profilpfosten 212 ist ein Handlauf 230 angebracht.The Fig. 14a to 14c show various views of a guard rail construction 200, which is for example mounted on a bridge. The profile posts 212 are screwed here via screws 228 with the substrate (not shown here). Likewise, the deformation element 226 is screwed with the attached support member 216 with both the profile post 212 and the guard rail 214. One recognizes further from the Figures 14a and 14c in that the profile posts 212 extend vertically further upwards and at the upper end of the profile posts 212 a handrail 230 is attached.

Fig. 15 zeigt eine Seitenansicht einer dritten Ausführungsform der Schutzplankenkonstruktion 300, mit zwei im Wesentlichen parallel verlaufenden Schutzplankensträngen 314. Fig. 15 shows a side view of a third embodiment of the guard rail construction 300, with two substantially parallel protective barrier strands 314th

Man erkennt aus Fig. 15 die beiderseits des Profilpfostens 312 angeordneten Stützelemente 316, die zusammen mit den Zwischenelementen 320 den Winkel der Schutzplankenstränge 314 zu der Längsachse L der Profilpfosten 312 einstellen. Es handelt sich bei den Stützelementen 316 um Stützelemente gemäß dem mit Bezug auf die Figuren 4a, 4b und 6 ausführlich beschriebenen ersten Ausführungsbeispiel.One recognizes Fig. 15 the support members 316 arranged on both sides of the profile post 312, which together with the intermediate elements 320 set the angle of the protective barrier strands 314 relative to the longitudinal axis L of the profile posts 312. It is at the support members 316 to support elements according to the with reference to the FIGS. 4a, 4b and 6 described in detail first embodiment.

Ferner wird aus Fig. 15 ersichtlich, dass die beiden Schutzplankenstränge 314 aufgrund des Zwischenelements 320 und der Stützelemente 316 entgegengesetzt abgewinkelt zur Längsachse L der Profilpfosten 312 bzw. zu dem Untergrund U verlaufen, um eine derartige Schutzplankenkonstruktion 300 beispielsweise als Mittelleitplanke zur Trennung zweier Fahrbahnen einsetzen und beidseitig die voranstehend ausführlich beschriebenen Vorteile einer derartigen Schutzplankenkonstruktion 300 nützen zu können. Mit anderen Worten können mit der Schutzplankenkonstruktion 300, die zwei im Wesentlichen parallel verlaufende Schutzplankenstränge 314 aufweist, von beiden Seiten anprallende Fahrzeuge am Überfahren der Schutzplankenstränge 314 gehindert werden und auch größere Fahrzeuge sicher umgelenkt werden.It also turns off Fig. 15 It can be seen that the two guard rail strands 314 due to the intermediate member 320 and the support members 316 opposite angled to the longitudinal axis L of the profile post 312 or to the substrate U run to use such a protective structure 300, for example, as a central barrier for the separation of two lanes and both sides described in detail above Benefits of such a protective barrier construction 300 to be able to use. In other words, with the guard rail construction 300 having two substantially parallel guardrail strands 314, vehicles bouncing off both sides can be prevented from passing over the guardrail strands 314 and even larger vehicles can be safely deflected.
