Description

Die Erfindung betrifft eine Leitschwellenanordnung gemäß den Merkmalen im Oberbegriff des Anspruchs 1.The invention relates to a Leitschwellenanordnung according to the features in the preamble of claim 1.

Es bildet ein in der Praxis einen immer größer werdenden Anteil nehmendes Problem, dass die Unfallhäufigkeit, insbesondere aber die Schwere der Unfälle, auf von Bäumen oder vergleichbaren Hindernissen gesäumten Straßen stark zunimmt. Es ist gar nicht so selten, dass diese Unfälle tödlich enden.It is an increasing problem in practice that the frequency of accidents, and in particular the severity of accidents, increases greatly on roads lined by trees or similar obstacles. It is not at all so rare that these accidents end in death.

Da in der Regel die Bäume unmittelbar am Rande einer Fahrbahn stehen und sie aus diversen Gründen, insbesondere aber des Umwelt- und Naturschutzes, nicht entfernt werden dürfen, ist es in den meisten Fällen nicht möglich, Leitschwellenanordnungen mit einer höheren Aufhaltestufe vor den Bäumen anzuordnen. Es wird dann meistens nur eine einfache Leitschwellenanordnung vorgesehen, die am Boden festgelegte Pfosten und einen sich fahrbahnseitig entlang der oberen Enden der Pfosten erstreckenden Leitplankenstrang aus schussweise miteinander lösbar verbundenen Leitplanken mit einem W-förmigen Querschnitt aufweist. Eine derartige Leitschwellenanordnung bietet aber keinen ausreichenden Schutz, da die zur Energie umformenden Umlenkung eines aufprallenden Kraftfahrzeugs notwendige Ausbeulung des Leitplankenstrangs nicht stattfinden kann. Vielmehr entsteht in dem Leitplankenstrang vor einem Baum ein sogenannter Sack mit der Folge, dass das Kraftfahrzeug mit seiner gesamten Wucht auf den Baum prallt. Die Schwere des Unfalls ist damit vorprogrammiert.Since the trees are usually located directly on the edge of a roadway and they may not be removed for various reasons, but in particular the environmental and nature protection, it is not possible in most cases, to arrange guard rail assemblies with a higher containment level in front of the trees. It is then usually only a simple Leitschwellenanordnung provided, the fixed to the ground posts and a road side along the upper ends of the post extending guardrail of weftwise releasably connected guardrails having a W-shaped cross-section. However, such a Leitschwellenanordnung does not provide adequate protection, since the energy deforming deflection of an impacting motor vehicle necessary bulging of the guardrail strand can not take place. Rather, in the guardrail strand in front of a tree, a so-called bag with the result that the motor vehicle collides with its entire force on the tree. The severity of the accident is thus inevitable.

Der Erfindung liegt - ausgehend vom Stand der Technik - die Aufgabe zugrunde, eine Leitschwellenanordnung entlang von mit Hindernissen, wie insbesondere Bäumen, besäumten Straßen zu schaffen, die ein aufprallendes Kraftfahrzeug sicher umlenkt.The invention is - based on the prior art - the object of providing a Leitschwellenanordnung along with obstacles, such as trees in particular, trimmed roads that deflects an impacting motor vehicle safely.

Diese Aufgabe wird mit den im Anspruch 1 angegebenen Merkmalen gelöst.This object is achieved with the features specified in claim 1.

Dort, wo sich im Verlauf einer Leitschwellenanordnung ein Hindernis befindet, wie insbesondere ein Baum, das im Falle eines Aufpralls durch ein Kraftfahrzeug die gewünschte Ausbeulung des Leitplankenstrangs verhindert und statt dessen vor dem Hindernis eine gefährliche Sackbildung erlaubt, wird nunmehr der Leitplankenstrang gezielt versteift. Dazu wird der Freiraum zwischen dem Leitplankenstrang und den ihn tragenden Pfosten genutzt. In diesen Freiraum wird in Abhängigkeit von dem Leitplankentyp mindestens ein zu dem Leitplankenstrang hin offener U- oder trapezförmiger Stützholm eingegliedert. Dieser Stützholm liegt mit seinem Steg an den Pfosten und greift mit den Längskanten seiner Schenkel in zu den Pfosten konkav gekrümmte Längsmulden der Leitplanken ein. Auf diese Weise werden die gegenüber den zentralen Stegen der Leitplanken nach oben und unten ragenden Schenkel der Leitplanken verstärkt, der gesamte Leitplankenstrang ausgesteift und ein Einknicken mit der Gefahr einer Sackbildung erheblich erschwert. Wie viele Stützholme im Verlauf eines Leitplankenstrangs integriert werden, hängt von der Anzahl der Hindernisse und/oder dem Abstand der Hindernisse voneinander ab.Where there is an obstacle in the course of a Leitschwellenanordnung, in particular a tree that prevents the event of an impact by a motor vehicle, the desired bulging of the guardrail and instead allows dangerous bag formation before the obstacle, now the guardrail strand is stiffened targeted. For this purpose, the space between the guard rail and the post carrying it is used. In this free space, depending on the guard rail type, at least one U-shaped or trapezoidal support spar open to the guard rail is incorporated. This support beam lies with its web on the posts and engages with the longitudinal edges of his legs in concave to the posts longitudinal recesses of the guardrails. In this way, compared to the central webs of the guardrails upwardly and downwardly projecting legs of the guardrails are reinforced, the entire guardrail strand stiffened and buckling with the risk of bagging considerably more difficult. How many support spars are integrated in the course of a guardrail strand depends on the number of obstacles and / or the distance of the obstacles from each other.

Diese Maßnahme kann sowohl bei der Erstinstallation einer Leitschwellenanordnung als auch bei einem bereits vorhandenen einfachen Leitschwellenstrang vorgenommen werden. Optisch ändert sich von der Fahrbahn her gesehen nichts an dem installiert gewesenen Leitplankenstrang.This measure can be made both in the initial installation of a Leitschwellenanordnung as well as an existing simple Leitschwellenstrang. Visually changes seen from the roadway ago nothing s.den installed installed guard rail.

Der Betrachter sieht keinen Unterschied. Er akzeptiert das für ihn gewohnte Bild. Auch brauchen bei einer Nachrüstung keine umfangreichen Montagearbeiten durchgeführt zu werden. Es müssen lediglich die Verbindungen zwischen dem Leitplankenstrang und den Pfosten gelöst, dann die Stützholme eingeführt und zum Schluss die Verbindungen wieder hergestellt zu werden.The viewer sees no difference. He accepts the picture he is used to. Also need to be carried out at a retrofit no extensive installation work. It only needs the connections between the guardrail strand and the posts solved, then introduced the support bars and finally the compounds to be restored.

Weisen die Leitplanken einen Querschnitt mit zwei zur Fahrbahn hin ragenden Wulsten auf (A-Profil), so gelangt ein im Querschnitt U-förmiger Stützholm zum Einsatz, bei dem die Längskanten seiner Schenkel in die durch die Wulste gebildeten rückseitigen Längsmulden fassen. Bei einer Leitplanke, die neben dem zur Fahrbahn hin offenen zentralen Kanal nach oben und unten ragende, sich in einer Ebene erstreckende flächige Bereiche aufweist (B-Profil), wird ein im Querschnitt trapezförmiger Stützholm verwendet, bei welchem die Längskanten seiner schräg nach oben und unten gerichteten Schenkel in die Längsmulden fassen, welche durch die Übergänge zwischen den flächigen Bereichen und den sich daran anschließenden, zu den Pfosten hin weisenden Randstreifen gebildet werden.If the crash barriers have a cross section with two beads projecting towards the roadway (A-profile), then a U-shaped support spar is used, in which the longitudinal edges of its legs grip into the rear longitudinal depressions formed by the beads. In a guardrail, which in addition to the road towards open central channel upwardly and downwardly projecting, extending in a plane planar areas (B-profile), a trapezoidal in cross-section support spar is used, in which the longitudinal edges of its obliquely upwards and directed down legs in the longitudinal troughs, which are formed by the transitions between the flat areas and the adjoining, pointing to the posts edge strips.

Die Montage eines Stützholms wird gemäß den Merkmalen des Anspruchs 2 dadurch erleichtert, dass der Stützholm zusammen mit den Leitplanken durch Schraubbolzen und Muttern an den im Standardabstand von 2 m oder 4 m aufeinander folgenden Pfosten festgelegt ist.The assembly of a support beam is facilitated by the features of claim 2, characterized in that the support beam is fixed together with the crash barriers by bolts and nuts to the standard distance of 2 m or 4 m consecutive post.

Entsprechend den Merkmalen des Anspruchs 3 ist im Stoßbereich zweier Leitplanken der Steg des Stützholms mit Montageöffnungen versehen. Da der Stützholm oder die Stützholme vor den Leitplanken an den Pfosten festgelegt werden, müssen die Schraubverbindungen der Überlappungsbereiche der Leitplanken von der der Fahrbahn abgewandten Rückseite her erreichbar sein. Die Größe der Montageöffnungen ist an die zur Handhabung der Schraubverbindungen verwendeten Werkzeuge angepasst.According to the features of claim 3, the web of the support spar is provided with mounting holes in the joint area of two crash barriers. Since the support strut or the support struts are fixed to the posts in front of the crash barriers, the screw connections of the overlapping areas of the guardrails must be accessible from the rear side facing away from the roadway. The size of the mounting holes is adapted to the tools used to handle the screw.

Ausweislich der Merkmale des Anspruchs 4 ist der Steg des Stützholms mit einer Vielzahl von in einer Reihe angeordneten Bohrungen versehen. Auf diese Weise kann den Verhältnissen im Umfeld eines Hindernisses, insbesondere eines Baums, und hierbei dem Wurzelwerk, Rechnung getragen werden. Die Pfosten können dann jeweils dort am Boden festgelegt, insbesondere in den Boden gerammt werden, wo es das Wurzelwerk zulässt. Dies ist insbesondere bei einer Nachrüstung eines bestehenden Leitplankenstrangs mit Stützholmen von Vorteil. Außerdem ermöglicht die Vielzahl von Bohrungen, dass die Pfosten in der Nähe des Hindernisses in einem vergleichsweise geringen Abstand gesetzt werden können. Hierdurch wird die Steifheit der Leitschwellenanordnung zusätzlich heraufgesetzt.As shown in the features of claim 4, the web of the support beam is provided with a plurality of holes arranged in a row. In this way, the conditions in the environment of an obstacle, in particular a tree, and here the root system, are taken into account. The posts can then each set there on the ground, in particular rammed into the ground, where it allows the root system. This is particularly advantageous when retrofitting an existing guardrail strand with support bars. In addition, the plurality of holes allows the posts in the vicinity of the obstacle can be set in a relatively small distance. As a result, the rigidity of the Leitschwellenanordnung is additionally increased.

Im Hinblick darauf, dass bei den zusätzlichen Schraubverbindungen zwischen einem Stützholm und den Pfosten die Köpfe der Schraubbolzen in Richtung zur Fahrbahn vorstehen, ist nach den Merkmalen des Anspruchs 5 vorgesehen, dass im Bereich der Schraubverbindungen zwischen den Stegen der Leitplanken und dem Steg des Stützholms Distanzplatten vorgesehen sind. Diese Distanzplatten halten folglich die Stege der Leitplanken im Abstand zum Steg des Stützholms und berücksichtigen hierbei die horizontale Länge der Schraubbolzenköpfe.In view of the fact that protrude in the direction of the roadway in the additional screw between a support beam and the post, the heads of the bolts, according to the features of claim 5 that in the region of the screw between the webs of the crash barriers and the web of the support spar spacer plates are provided. Consequently, these spacer plates keep the webs of the crash barriers at a distance from the web of the support spar and take into account the horizontal length of the screw bolt heads.

Gelangen zwei oder mehrere Stützholme zum Einsatz, so ist es gemäß Anspruch 6 von Vorteil, dass zwei aufeinander folgende Stützholme durch die Enden ihrer Stege und ihrer Schenkel übergreifende, zu den Stützholmen hin kongruent ausgebildete Kuppelprofile sowie durch Schraubbolzen und Muttern lösbar verbunden sind.If two or more support beams are used, then it is advantageous according to claim 6 that two successive support beams are releasably connected by the ends of their webs and their legs, dome profiles which are congruent with the support struts and by bolts and nuts.

Mit 1 ist in der Figur 1 eine Leitschwellenanordnung bezeichnet, die sich entlang einer am Rand mit Bäumen 2 bestandenen Fahrbahn 3 erstreckt.1 designates in FIG. 1 a threshold barrier arrangement which extends along a roadway 3 that has been bordered by trees 2.

Wie bei gemeinsamer Betrachtung der Figuren 1 und 3 zu erkennen ist, weist die Leitschwellenanordnung 1 in den Boden 4 gerammte Pfosten 5 sigmaförmigen Querschnitts und einen sich fahrbahnseitig entlang der oberen Enden 6 der Pfosten 5 erstreckenden Leitplankenstrang 7 aus schussweise miteinander lösbar verbundenen Leitplanken 8 auf.As can be seen in a joint consideration of Figures 1 and 3, the Leitschwellenanordnung 1 rammed into the ground 4 posts 5 sigma-shaped cross-section and a roadway along the upper ends 6 of the post 5 extending guard rail 7 from each other in a detachable manner connected guardrails 8 on.

Die Leitplanken 8 besitzen einen W-förmigen Querschnitt, der sich aus einem zentralen Steg 9, daran nach oben und unten anschließenden V-förmigen Wulsten 10 mit zur Fahrbahn 3 hin konvex gekrümmten Stirnseiten 11 und an die Wulste 10 anschließenden, von der Fahrbahn 3 weg gerichteten Randstreifen 12 zusammensetzt.The guardrails 8 have a W-shaped cross section, which consists of a central web 9, up and down adjoining V-shaped beads 10 with the roadway 3 convexly curved end faces 11 and adjoining the beads 10, away from the roadway 3 away directed edge strip 12 composed.

Im Bereich eines Baums 2 (siehe Figuren 1 bis 4) sind zwischen die Leitplanken 8 und die Pfosten 5 zu den Leitplanken 8 hin offene U-förmige Stützholme 13 eingegliedert. Die Stützholme 13 liegen mit ihren Stegen 14 an den Pfosten 5 und greifen mit den Längskanten 15 ihrer Schenkel 16 in die durch die Wulste 10 gebildeten, zu den Pfosten 5 hin konkav gekrümmten Längsmulden 17 der Leitplanken 8 ein. Die Verbindungen zwischen den Leitplanken 8 und den Pfosten 5 bestehen aus Schraubbolzen 18 und Muttern 19, wobei die Schraubbolzen 18 von den zur Fahrbahn 3 hin offenen zentralen Kanälen 20 der Leitplanken 8 her durch Bohrungen in den Stegen 9 eingeführt werden. Dabei werden zwischen den Stegen 9 der Leitplanken 8 und den Stegen 14 der Stützholme 13 Distanzplatten 21 vorgesehen. Diese Distanzplatten 21 berücksichtigen gemäß der Darstellung der Figur 4 die axiale Länge der Köpfe 22 von Schraubbolzen 23, mit welchen die Stützholme 13 an den Pfosten 5 festgelegt werden, die sich zwischen den im Standardabstand A von 2 m oder 4 m (je nach Länge der Leitplanken) angeordneten Pfosten 5 befinden. Zu diesem Zweck sind in den Stegen 14 der Stützholme 13 eine Vielzahl von in einer Reihe angeordneten Bohrungen 24 vorgesehen. Auf diese Weise kann, wie insbesondere die Figuren 1 und 2 erkennen lassen, nicht nur dem Wurzelwerk 25 eines Baumes 2 Rechnung getragen werden, sondern es wird auch eine zusätzliche Versteifung der Leitschwellenanordnung 1 aufgrund weiterer in den Boden 4 gerammter Pfosten 5 erzielt.In the area of a tree 2 (see FIGS. 1 to 4), U-shaped support struts 13, which are open towards the crash barriers 8, are incorporated between the crash barriers 8 and the posts 5. The support struts 13 are with their webs 14 to the post 5 and engage with the longitudinal edges 15 of their legs 16 in the formed by the beads 10, to the post 5 concave longitudinal recesses 17 of the crash barriers 8 a. The connections between the guardrails 8 and the posts 5 consist of bolts 18 and nuts 19, wherein the bolts 18 are introduced from the roadway 3 towards the open central channels 20 of the crash barriers 8 forth through holes in the webs 9. In this case 13 spacer plates 21 are provided between the webs 9 of the crash barriers 8 and the webs 14 of the support bars. These spacer plates 21 take into account in the illustration of Figure 4, the axial length of the heads 22 of bolts 23, with which the support bars 13 are fixed to the post 5, which is between the standard spacing A of 2 m or 4 m (depending on the length of the guardrails) arranged posts 5 are. For this purpose, a plurality of bores 24 arranged in a row are provided in the webs 14 of the support bars 13. In this way, as can be seen in particular Figures 1 and 2, not only the root system 25 of a tree 2 are taken into account, but it is also an additional stiffening of the Leitschwellenanordnung 1 due to further rammed into the ground 4 posts 5 achieved.

Aus der Figur 2 ist zu erkennen, dass zwei aufeinander folgende Stützholme 13 durch die Enden ihrer Stege 14 und ihrer Schenkel 16 übergreifende, zu den Stützholmen 13 hin kongruent ausgebildete Kuppelprofile 26 sowie durch nicht näher dargestellte Schraubbolzen und Muttern lösbar verbunden sind.From Figure 2 it can be seen that two consecutive support members 13 by the ends of their webs 14 and their legs 16 cross, to the support bars 13 congruent trained dome profiles 26 and are detachably connected by bolts and nuts not shown.

Bei der Montage der Leitschwellenanordnung 1 im Bereich eines Baums 2 werden nach dem Einrammen der Pfosten 5 zunächst die gegebenenfalls vorab über die Kuppelprofile 26 miteinander verbundenen Stützholme 13 an den zwischen den im Standardabstand A zueinander vorgesehenen Pfosten 5 mit Hilfe von Schraubbolzen 23 und Muttern 27 festgelegt (Figuren 2 und 4). Im Anschluss daran werden die Leitplanken 8 fahrbahnseitig angesetzt und gemeinsam mit den Stützholmen 13 an den im Standardabstand A vorgesehenen Pfosten 5 unter Eingliederung der Distanzplatten 21, Schraubbolzen 18 und Muttern 19 fixiert. Zu diesem Zweck sind, wie die Figur 2 erkennen lässt, im Stoßbereich 28 zweier Leitplanken 8 die Stege 14 der Stützholme 13 mit Montageöffnungen 29 versehen.When mounting the Leitschwellenanordnung 1 in the area of a tree 2 after the ramming of the post 5, the optionally pre-connected via the dome profiles 26 support beams 13 at the between the standard spacing A mutually provided post 5 by means of bolts 23 and nuts 27 set (Figures 2 and 4). Following this, the crash barriers 8 are attached to the roadway side and fixed together with the support bars 13 to the provided at standard distance A post 5 under inclusion of the spacer plates 21, bolts 18 and nuts 19. For this purpose, as can be seen from FIG. 2, the webs 14 of the support struts 13 are provided with mounting openings 29 in the joint area 28 of two guard rails 8.

Die Anzahl der zwischen den im Standardabstand A eingerammten Pfosten 5 vorgesehenen Pfosten 5 hängt davon ab, welche Stabilität die Leitschwellenanordnung 1 im Bereich des Baums 2 aufweisen soll und auch davon, wie das Wurzelwerk 25 des Baums 2 beschaffen ist. Die in den Stegen 14 der Stützholme 13 angeordneten Bohrungen 24 erlauben hierbei eine große Variation des Abstands benachbarter Pfosten 5 und auch hinsichtlich ihrer Anzahl.The number of posts 5 provided between the posts 5 driven in the standard distance A depends on the stability which the guide sill assembly 1 should have in the area of the tree 2 and also on how the root system 25 of the tree 2 is arranged. The arranged in the webs 14 of the support bars 13 holes 24 allow this a large variation of the distance between adjacent posts 5 and also in terms of their number.

Bei der Ausführungsform der Figur 5 gelangt ein Leitplankenstrang 7a zur Anwendung, der sich ebenfalls aus schussweise lösbar zusammengesetzten W-förmigen Leitplanken 8a zusammensetzt. Bei diesen Leitplanken 8a sind jedoch neben dem zur Fahrbahn 3 hin offenen zentralen Kanal 20a nach oben und unten sich in einer Ebene erstreckende flächige Bereiche 30 vorhanden, die an ihren oberen und unteren Enden in zu den Pfosten 5 hin abgekantete Randstreifen 31 übergehen. Um dieser Bauform von Leitplanken 8a im Rahmen der Erfindung Rechnung zu tragen, werden trapezförmige Stützholme 13a verwendet. Deren nach oben und unten schräg gerichtete Schenkel 16a fassen mit ihren Längskanten 15a in die konkav gekrümmten Längsmulden 17a zwischen den flächigen Bereichen 30 und den Randstreifen 31 ein.In the embodiment of FIG. 5, a guardrail strand 7a is used, which is likewise composed of W-shaped guardrails 8a which are detachably assembled in a weft-wise manner. In these crash barriers 8a, however, in addition to the to the roadway 3 open towards the central channel 20a up and down in a plane extending planar areas 30 present, which merge at their upper and lower ends in to the post 5 folded edge strips 31. In order to take account of this design of crash barriers 8a in the context of the invention, trapezoidal support bars 13a are used. Their obliquely upwardly and downwardly directed legs 16a engage with their longitudinal edges 15a in the concave longitudinal recesses 17a between the flat areas 30 and the edge strips 31 a.

Ansonsten entspricht die Ausführungsform der Figur 5 derjenigen der Figuren 1 bis 4, so dass nähere Erläuterungen entbehrlich sind.Otherwise, the embodiment of Figure 5 corresponds to that of Figures 1 to 4, so that further explanations are unnecessary.
