Description

Die Erfindung betrifft eine Fahrspurtrenneinrichtung zum Abbremsen, Zurückleiten oder Stoppen von von der Fahrbahn abkommenden Fahrzeugen, bestehend aus entlang der Fahrbahn oder zwischen deren Fahrspuren anzuordnenden, in Längsrichtung aneinandergereihten und miteinander in Verbindung stehenden Betonelementen von untereinander vorzugsweise gleicher Gestalt, die auf ihrer der von Fahrzeugen befahrenen Fahrbahn zugewandten Wandfläche eine schräg aufwärts verlaufende Anfahrfläche aufweisen und an ihren dazu senkrecht ausgerichteten Stirnflächen mit im Inneren des Betonelementes verankerten, als senkrecht angeordnete Platte ausgebildeten Verbindungsgliedern versehen sind, die bei stirnseitig dicht aneinandergestellten Betonelementen ineinandergreifen. The invention relates to a lane dividing device for Braking, returning or stopping from the road outgoing vehicles consisting of along the lane or to be arranged between their lanes, in Longitudinally lined up and with each other in Connected concrete elements from each other preferably of the same shape, based on that of A wall surface facing vehicles with a roadway have an inclined approach surface and on their vertically aligned end faces with in Anchored inside the concrete element as a vertically arranged plate trained links are provided, which at Concrete elements placed close together on the face mesh.

Eine derartige Fahrspurtrenneinrichtung ist beispielsweise aus der EP 0 589 073 bekannt. Gegenüber Fahrspurtrenneinrichtungen, die beispielsweise mit Hilfe von Gleitschalungen und Transportbeton vor Ort erstellt werden, besitzen solche aus einzelnen Betonelementen hergestellte Fahrspurtrenneinrichtungen den Vorteil, daß sie an geeigneten Fertigungsstätten unter günstigeren Bedingungen hergestellt und dann als fertige Teile zum Einsatzort transportiert werden können, wo sie mit Hilfe der Verbindungsglieder zu einem festem Verbund aneinander gereiht werden können. Die einzelnen Teile können auch in gewissen Fällen zusätzlich am Boden verankert werden, um den festen Verbund zu verbessern.Such a lane separator is for example known from EP 0 589 073. Across from Lane separation devices, for example with the help of sliding formwork and ready-mixed concrete created on site are made of individual concrete elements manufactured lane dividers the advantage that them at suitable manufacturing facilities under cheaper ones Conditions and then manufactured as finished parts Can be transported to where it is needed with the help of the connecting links together to form a firm bond can be ranked. The individual parts can also be in in certain cases to be additionally anchored to the ground to improve the firm bond.

Bei den bisher bekannten, aus einzelnen Betonelementen aufgebauten Fahrspurtrenneinrichtungen hat sich jedoch als nachteilig herausgestellt, daß beim Auffahren unter einem größeren Winkel erhebliche Seitenkräfte aufgenommen werden müssen, denen die Betonelemente unter Umständen nicht mehr Stand halten. Der Grund hierfür ist darin zu sehen, daß die von den Verbindungsgliedern ins Betonelement eingeleiteten Querkräfte zu Biege- und/oder Zugbelastungen im Beton führen, wodurch die Verbindungsglieder ausreißen können.In the previously known, from individual concrete elements built lane dividers has however proven to be disadvantageously pointed out that when opening under a larger angles significant lateral forces are absorbed which the concrete elements may no longer have Withstand. The reason for this is that that from the links into the concrete element initiated transverse forces for bending and / or tensile loads in the concrete, causing the links to tear can.

Der Erfindung liegt die Aufgabe zugrunde, eine Fahrspurtrenneinrichtung der eingangs genannten Art so auszubilden, daß sie in der Lage ist, auch größere Seitenkräfte ohne die Gefahr eines Ausreißens der Verbindungsglieder aufzunehmen, wie sie beim Auffahren unter größerem Winkel, insbesondere durch schwere Fahrzeuge auftreten können. The invention has for its object a Lane separation device of the type mentioned above train that she is able to handle even larger ones Lateral forces without the risk of tearing the Connect links as they do when opening at a larger angle, especially through heavy ones Vehicles can occur.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die Verbindungsglieder an einem Verankerungskorb angeschlossen sind, dessen senkrecht zur die Anfahrfläche aufweisenden Wandfläche sich erstreckende Breite und dessen Höhe wenigstens der Breite und Höhe des Verbindungsgliedes entspricht, wobei der Verankerungskorb von mehreren U-förmigen, übereinander mit gegenseitigem Abstand angeordneten Bügelteilen gebildet ist, die über senkrecht verlaufende Profilleisten miteinander verbunden und die Bügelteile an ihrem dem Verbindungsglied zugewandten Ende an einem gestreckt ovalförmigen Anschlußrahmen befestigt sind, wobei der Anschlußrahmen das Verbindungsglied umschließt und trägt.This object is achieved according to the invention in that the links on an anchoring basket are connected, its perpendicular to the approach area Wall surface itself extending width and its height at least the width and corresponds to the height of the connecting link, the Anchoring basket of several U-shaped, one on top of the other mutually spaced bracket parts formed is that over vertical profile strips connected together and the bracket parts on their the Link facing end stretched at one oval-shaped lead frames are attached, the Connection frame encloses and carries the connecting link.

Der durch die Erfindung erreichte Vorteil besteht im wesentlichen darin, daß der Verankerungskorb im Inneren des Betonelementes eine zusätzliche, die auftretenden Kräfte, insbesondere die Zug- und Scherkräfte aufnehmende Armierung bildet, so daß auch hohe, über die Verbindungsglieder in das Betonelement eingeleitete Querkräfte ohne Beschädigungen oder Zerstörungen des Betonelementes aufgenommen werden. Gleichzeitig wird die Betonqualität durch diese zusätzliche Armierung erhöht.The advantage achieved by the invention is essential in that the anchoring basket inside of the concrete element an additional, the occurring Forces, especially the tensile and shear forces Reinforcement forms, so that even high, over the Links introduced into the concrete element Transverse forces without damage or destruction of the Concrete element are included. At the same time, the Concrete quality increased through this additional reinforcement.

Günstig ist es hierbei weiter, wenn die Bügelteile untereinander gleichen Abstand aufweisen.It is also advantageous if the bracket parts have the same distance from each other.

Um das Auftreten lokaler Kräfte weiter zu vermindern, wird im Rahmen der Erfindung weiter vorgeschlagen, daß die Bügelteile im Bereich ihres Bügelrückens kreisbogenförmig verlaufen. Dadurch wird auch eine optimale Einbettung der zusätzlichen Armierung im Beton gewährleistet. In order to further reduce the occurrence of local forces, further proposed within the scope of the invention that the Temple parts in the area of their temple back in a circular arc run. This also ensures optimal embedding of the guaranteed additional reinforcement in the concrete.

Das Verbindungsglied kann zweckmäßigerweise aus einer im Querschnitt J-förmigen, dadurch einen Haken bildenden Verankerungsplatte bestehen, die auf ihrer den Haken aufweisenden Seite ein Winkelprofil trägt, wobei der Raum zwischen dem Winkelprofil und dem Haken eine Aufnahmekammer für das Verbindungsglied des angrenzenden Betonelements bildet. Der frei vorstehende Schenkel des Winkelprofils schließt dabei zweckmäßigerweise bündig mit der Stirnfläche des Betonelements ab.The connecting member can expediently from a Cross-section J-shaped, thereby forming a hook Anchor plate consist of the hook on it having side carries an angle profile, the space between the angle profile and the hook Admission chamber for the connecting link of the adjacent one Concrete element forms. The free protruding leg of the Angular profile expediently closes flush from the end face of the concrete element.

Schließlich ist im Rahmen der Erfindung vorgesehen, daß die beiden Verbindungsglieder eines Betonelements durch wenigstens eine Verbindungsstrebe miteinander verbunden sind. Auf diese Weise kann jedes Betonelement vergleichsweise hohe, auf die beiden Verbindungsglieder einwirkende Zugkräfte aufnehmen.Finally, the invention provides that through the two connecting links of a concrete element at least one connecting strut connected to each other are. In this way, any concrete element comparatively high, on the two links absorb acting tensile forces.

Im folgenden wird die Erfindung an einem in der Zeichnung dargestellten Ausführungsbeispiel näher erläutert; es zeigen:

The invention is explained in more detail below using an exemplary embodiment shown in the drawing; show it:

Die in der Zeichnung dagestellte Fahrspurtrenneinrichtung dient zum Abbremsen, Zurückleiten oder Stoppen von Fahrzeugen, die - aus welchen Gründen auch immer - von der vorgeschriebenen bzw. vorgesehenen Fahrbahn abkommen und damit Gefahr laufen, entweder beispielsweise über eine Böschung abzustürzen oder aber mit dem entgegenkommenden Verkehr zu kollidieren.The lane divider shown in the drawing is used for braking, returning or stopping Vehicles - for whatever reason - from the the prescribed or intended lane and thus run the risk, for example, via a Crash embankment or with the oncoming Traffic collide.

Dazu besteht die Fahrtspurtrenneinrichtung im einzelnen aus entlang der Fahrbahn oder zwischen deren Fahrspuren anzuordnenden Betonelementen 1 von untereinander vorzugsweise gleicher Gestalt, die in Längsrichtung aneinander gereiht werden und miteinander in Verbindung stehen. Die der von Fahrzeugen befahrenen Fahrbahn zugewandte Wandfläche 2 des Betonelements 1 weist, wie sich insbesondere aus den Fig. 2 und 3 ersehen läßt, eine schräg aufwärts verlaufende Anfahrfläche 3 auf, die einen harten Aufprall des Fahrzeugs an dem Betonelement aufnimmt.For this purpose, the lane separation device exists in detail from along the lane or between its lanes to be arranged concrete elements 1 of each other preferably of the same shape in the longitudinal direction to be strung together and in connection with each other stand. That of the lane used by vehicles facing wall surface 2 of the concrete element 1 has how can be seen in particular from FIGS. 2 and 3, a sloping upward approach surface 3, the one hard impact of the vehicle on the concrete element receives.

An ihren senkrecht zu den Wandflächen 2 ausgerichteten Stirnflächen 4 sind die Betonelemente 1 mit im Inneren verankerten Verbindungsgliedern 5 versehen, die bei stirnseitig dicht aneinander gestellten Betonelementen 1 ineinander greifen. On their perpendicular to the wall surfaces 2 End faces 4 are the concrete elements 1 with inside anchored links 5 provided at Concrete elements placed close together on the face 1 mesh.

Da beim Auffahren unter einem relativ großen Winkel hohe Seitenkräfte auftreten, die zunächst von den Verbindungsgliedern 5 aufgenommen und ins Innere der Betonelemente 1 geleitet werden, besteht durch das Auftreten hoher Zugbelastungen die Gefahr, daß Teile der Betonelemente 1 ausbrechen, möglicherweise sogar das Verbindungsglied sich vollständig löst. Um diese Gefahr zu beseitigen oder zumindest zu verkleinern, sind die Verbindungsglieder 5 an einen Verankerungskorb 6 angeschlossen. Dieser Verankerungskorb 6 ist so gestaltet, daß dessen senkrecht zur Wandfläche 2 sich erstreckende Breite und dessen Höhe wenigstens der Breite und der Höhe des Verbindungsgliedes 5 entspricht. Auf diese Weise wird jedenfalls ein erheblicher Teil der am Verbindungsglied 5 auftretenden Kräfte in den sich über ein größeres Volumen im Betonelement 1 erstreckenden Verankerungskorb 6 abgeleitet, wodurch insgesamt höhere Querkräfte aufgenommen werden können.Because when opening at a relatively large angle high Lateral forces occur, initially from the Links 5 added and inside the Concrete elements 1 are passed through Occurrence of high tensile loads the risk that parts of the Break out concrete elements 1, possibly even that Link completely detaches. To avoid this danger eliminate or at least reduce, they are Links 5 to an anchoring basket 6 connected. This anchoring basket 6 is designed that its perpendicular to the wall surface 2 extending Width and its height at least the width and the height of the link 5 corresponds. That way in any case a significant part of that on the connecting member 5 forces occurring in the over a larger volume in the concrete element 1 anchoring basket 6 derived, resulting in higher overall lateral forces can be included.

Wie sich insbesondere aus den Fig. 1 und 4 ersehen läßt, ist der Verankerungskorb 6 von mehreren U-förmigen, übereinander mit gegenseitigem Abstand angeordneten Bügelteilen 7 gebildet, die über senkrecht verlaufende Profilleisten 8 miteinander verbunden sind. Die Bügelteile 7 weisen dabei untereinander gleichen Abstand auf. Im Ausführungsbeispiel sind, wie Fig. 1 zeigt, insgesamt 6 derartige Bügelteile 7 vorgesehen, die über insgesamt fünf Profilleisten 8 miteinander verbunden sind. Im Bereich ihres Bügelrückens verlaufen die Bügelteile 7, wie sich aus Fig. 4 ersehen läßt, kreisbogenförmig, wodurch das Auftreten lokaler Kraftspitzen vermieden wird. Wie sich insbesondere aus den Fig. 2 und 3 ersehen läßt, sind die Bügelteile 7 an ihrem dem Verbindungsglied 5 zugewandten freien Ende an einem gestreckt ovalförmigen Anschlußnahmen 9 befestigt. Dieser Anschlußrahmen 9 umschließt und trägt dabei auch das Verbindungsglied 5. Das Verbindungsglied 5 kann dabei in nicht näher dargestellter Weise am Anschlußrahmen 9 beispielsweise angeschweißt sein.As can be seen in particular from FIGS. 1 and 4, is the anchoring basket 6 of several U-shaped, arranged one above the other at a mutual distance Bracket parts 7 formed, the vertical Profile strips 8 are interconnected. The Bracket parts 7 have the same distance from each other on. In the exemplary embodiment, as shown in FIG. 1, A total of 6 such bracket parts 7 are provided, which a total of five profile strips 8 are connected to each other. The temple parts 7, as can be seen from FIG. 4, in the shape of a circular arc, whereby the occurrence of local force peaks is avoided. As can be seen in particular from FIGS. 2 and 3, are the bracket parts 7 on their connecting link 5 facing free end on a stretched oval Connections 9 attached. This lead frame 9 encloses and also carries the connecting member 5. The connecting link 5 can not in more detail illustrated manner on the lead frame 9, for example be welded on.

Das Verbindungsglied 5 selbst ist von einer im Querschnitt J-förmigen Verankerungsplatte gebildet, die dadurch eine im Querschnitt hakenförmige Gestalt besitzt, wie sich dies gut aus der Figur 4 ersehen läßt. Um für das entsprechend hakenförmig ausgebildete Verbindungsglied 5 des benachbarten Betonelements eine geeignete Aufnahmekammer 11 zu bilden, trägt das Verbindungsglied 5 auf ihrer den Haken aufweisenden Seite ein Winkelprofil 10. Der Raum zwischen dem Winkelprofil 10 und dem Haken bildet damit die Aufnahmekammer 11. Der freivorstehende Schenkel des Winkelprofils 10 schließt dabei bündig mit der Stirnfläche des Betonelements 1 ab. Um im übrigen auch reine Zugkräfte ohne weiteres aufnehmen zu können, sind die beiden Verbindungsglieder 5 eines Betonelements 1 durch wenigstens eine Verbindungstrebe 12 miteinander verbunden, wie sich dies aus der Fig. 4 ergibt.The connecting link 5 itself is of a cross section J-shaped anchoring plate formed, which thereby a has a hook-like shape in cross-section, as is the case with this can be seen well from Figure 4. In order for that accordingly hook-shaped link 5 of the a suitable concrete element To form the receiving chamber 11 carries the link 5 on their hooked side Angle profile 10. The space between the angle profile 10 and the hook thus forms the receiving chamber 11. The protruding leg of the angle profile 10 closes thereby flush with the end face of the concrete element 1. In order to absorb pure tensile forces without further ado to be able to, the two connecting links 5 are one Concrete element 1 by at least one connecting strut 12 connected to one another, as can be seen in FIG. 4 results.
