Description

Die Erfindung betrifft eine Leitwand für Verkehrswege mit Beton-Wandelementen, die im Inneren verlaufende Zugbänder aufweisen, deren Enden mit stirnseitigen Eingriffselementen versehen sind, in welche Kupplungs-Zugglieder zur kraftschlüssigen Verbindung von jeweils benachbarten Beton-Wandelementen einsetzbar sind, wobei die Beton-Wandelemente durch wenigstens ein, vorzugsweise im wesentlichen L- oder U-förmiges, Klammerelement verbunden sind.The invention relates to a baffle for traffic routes with concrete wall elements having extending inside drawstrings whose ends are provided with frontal engagement elements, in which coupling tension members for non-positive connection of adjacent concrete wall elements can be used, wherein the concrete wall elements at least one, preferably substantially L- or U-shaped, clamping element are connected.

Mit Beton-Wandelementen der vorgenannten Art, wie in WO 98/19015 offenbart, kann eine wirkungsvolle Trennung von Verkehrsströmen vor allem im Gegenverkehrsbereich erreicht werden, die im Gegensatz zu einfachen Bodenmarkierungen auch eine mechanisch wirkende Begrenzung der Fahrbahnen darstellt, wobei die Beton-Wandelemente eine nur geringe wirksame Aufstellungsbreite in Anspruch nehmen.With concrete wall elements of the aforementioned type, as in WO 98/19015 discloses an effective separation of traffic flows, especially in the oncoming traffic area can be achieved, which also represents a mechanically acting boundary of the lanes, in contrast to simple ground markings, the concrete wall elements take only a small effective installation width to complete.

Nachteilig an diesen bekannten Beton-Wandelementen ist, dass bei einem Aufprall aufgrund der auftretenden Belastungen die Verankerungselemente versagen und sich die Abstützelemente vom Beton-Wandelement teilweise lösen können. Dabei kann es sein, dass nach dem Aufprall wenigstens ein Abstützelement in den Gegenverkehrsbereich ragt, wodurch dort die Unfallgefahr erhöht wird. Weiters ist es bei diesen Beton-Wandelementen nachteilig, dass nach dem Versagen der Verankerungselemente die Reibung des Beton-Wandelementes herabgesetzt ist, wodurch es zu größeren Verschiebungen der Beton-Wandelemente in den Gegenverkehrsbereich kommen kann. Bei dieser Verschiebung bilden sich an den Stoßstellen zweier Beton-Wandelemente Knickstellen aus.A disadvantage of these known concrete wall elements that fail in an impact due to the loads occurring anchoring elements and the support elements of the concrete wall element can partially solve. It may be that after impact at least one supporting element projects into the oncoming traffic area, whereby there the risk of accidents is increased. Furthermore, it is disadvantageous in these concrete wall elements that after the failure of the anchoring elements, the friction of the concrete wall element is reduced, which can lead to larger shifts of the concrete wall elements in the oncoming traffic area. During this displacement, kinks are formed at the joints of two concrete wall elements.

Bekannte Beton-Wandelemente aus Metall können relativ schmal ausgebildet werden, sie sind aber wesentlich geringfügig belastbarer als Beton-Wandelemente. Daher kann es bei Ihnen zu großen Verschiebungen bzw. Deformationen kommen, die in den Gegenverkehrsbereich ragen.Known concrete wall elements made of metal can be made relatively narrow, but they are significantly more resilient than concrete wall elements. Therefore, you may experience large displacements or deformations that protrude into the oncoming traffic.

Aufgabe der Erfindung ist es das Verschieben von Teilen der Leitwand in den Gegenverkehrsbereich, insbesondere das Ausbilden einer Knickstelle an der Stoßstelle zwischen zwei Beton-Wandelementen, zu verhindern.The object of the invention is to prevent the shifting of parts of the baffle in the oncoming traffic area, in particular the formation of a kink at the junction between two concrete wall elements.

Aufgabe ist es daher, die Leitwand der eingangs genannten Art anzugeben, die eine ausreichend stabile Aufstellung bei relativ geringer wirksamer Breite ermöglicht, sodass nach einem Aufprall der Gegenvcrkehrsbereich nicht behindert wird. Insbesondere soll das Abragen eines der Abstützelemente nach einem Aufprall verhindert werden. Erfindungsgemäß wird dies dadurch erreicht, dass die Klammerelemente im Bereich zwischen den Beton-Wandelementen Querstege aufweisen.The object is therefore to provide the baffle of the type mentioned, which allows a sufficiently stable installation at relatively low effective width, so that after an impact of Gegenvcrkehrsbereich is not hindered. In particular, the projecting of one of the support elements to be prevented after an impact. According to the invention this is achieved in that the clip elements have transverse webs in the region between the concrete wall elements.

Das Klammerelement verstärkt die Stoßstelle und verhindert dadurch ein Ausknicken der Beton-Wandelemente.The clamp element reinforces the joint and thereby prevents buckling of the concrete wall elements.

Durch die Querstege kann die Steifigkeit der Klaminerelemente weiter verbessert werden.The transverse webs, the stiffness of the Klaminerelemente can be further improved.

In Weiterbildung der Erfindung kann vorgesehen sein, dass die Beton-Wandelemente und die Klammerelemente Bohrungen aufweisen, wodurch sie mittels Befestigungselementen, insbesondere Schrauben od. dgl., verbindbar sind.In a further development of the invention can be provided that the concrete wall elements and the clip elements have holes, whereby they od by means of fastening elements, in particular screws. Like., Are connectable.

Durch diese lösbare Verbindung können die Beton-Wandelemente bei der Errichtung einer erfindungsgemäßen Leitwand schnell miteinander verbunden werden, wobei gewährleistet ist, dass die Verbindung auch bei einem Aufprall nicht gelöst wird.By means of this detachable connection, the concrete wall elements can be quickly connected to one another in the construction of a guide wall according to the invention, it being ensured that the connection is not released even in the event of an impact.

In weiterer Ausgestaltung der Erfindung kann vorgesehen sein, dass die Beton-Wandelemente und die Klammerelemente ein vorbestimmbares Spiel aufweisen.In a further embodiment of the invention can be provided that the concrete wall elements and the clip elements have a predeterminable game.

Durch das Vorhandensein eines Spiels kann die erfindungsgemäße Leitwand bei einem Aufprall mit niedriger oder mittlerer Energie, z.B. bei einem Aufprall eines PKW, als überwiegend nachgiebige Leitwand und bei einem Aufprall mit hoher Energie, z.B. bei einem Aufprall eines LKW, als überwiegend starre Leitwand ausgebildet werden.Due to the presence of a play, the baffle of the invention may be subject to a low or medium energy impact, e.g. in the event of a car impact, as a predominantly resilient baffle, and in a high energy impact, e.g. be formed in a collision of a truck as a predominantly rigid baffle.

In Weiterführung der Erfindung kann vorgesehen sein, dass die Klammerelemente im Kopfbereich und/oder im Fußbereich der Leitwand angeordnet sind/ist.In continuation of the invention can be provided that the clip elements are arranged in the head area and / or in the foot region of the baffle / is.

Durch die Anbringung der Klammerelemente im Kopf- und/oder Fußbereich kann der Auf- bzw. Abbau der erfindungsgemäßen Leitwand in kurzer Zeit erfolgen.By attaching the clip elements in the head and / or foot area of the construction or dismantling of the baffle according to the invention can be done in a short time.

Gemäß einer weiteren Ausbildung der Erfindung kann vorgesehen sein, dass im Bereich der Stoßstelle zwischen den Stirnseiten benachbarter Beton-Wandelemente jeweils zumindest ein flächiges, elastisches Druekausgleiehselement formschlüssig angeordnet ist.According to a further embodiment of the invention can be provided that in the region of the joint between the end faces of adjacent concrete wall elements in each case at least one flat, elastic Druekausgleiehselement is arranged positively.

Durch die Anbringung des Druckausgleichselements kann die Neigung zur Ausbildung einer Knickstelle an der Stoßstelle zwischen den Stirnseiten benachbarter Beton-Wandelemente weiter verringert werden.By attaching the pressure compensation element, the tendency to form a kink at the junction between the end faces of adjacent concrete wall elements can be further reduced.

In Weiterbildung kann vorgesehen sein, dass wenigstens jeweils eines der Abstützelemente benachbarter Beton-Wandelemente zusätzlich durch Kupplungs-Druckglieder aneinander abgestützt sind.In a further development, it can be provided that at least one of the support elements of adjacent concrete wall elements is additionally supported by coupling pressure members to one another.

Durch die seitliche Anbringung der Kupplungs-Druckglieder an den Abschlußelementen können auch Biegemomente übertragen werden, wodurch das Ausbilden einer Knickstelle an der Stoßstelle zwischen zwei Beton-Wandelementen erschwert wird. Weiters wird auch eine Querkraftübemagung durch die Kupplungs-Druckglieder gewährleistet.By the lateral attachment of the coupling-pressure members on the closure elements and bending moments can be transmitted, thereby forming a kink the joint between two concrete wall elements is difficult. Furthermore, a lateral force transfer is ensured by the coupling pressure members.

In den Fig. 1 bis 3 sind die Seitenansicht, die Draufsicht und die Stirnansicht einer Ausführungsform eines erfindungsgemäßen Beton-Wandelementes 1 dargestellt, wie sie für ein Rückhaltesystem auf Straßen verwendet werden kann. Das Beton-Wandelement 1 weist entlang seiner beiden Längsseiten Abstützelemente 2 auf. Die Abstützelemente 2 erstrecken sich bei dieser Ausführungsform über die gesamte Länge des Beton-Wandelementes 1. Bei anderen Ausführungsformen erstrecken sich die Abstützelemente 2 nur über einen Teil der Länge des Beton-Wandelementes 1, wobei es auch sein kann, dass mehrere Abstützelemente 2 an einer Längsseite des Beton-Wandelementes 1 angeordnet sind.In the Fig. 1 to 3 For example, the side view, the top view and the front view of an embodiment of a concrete wall element 1 according to the invention, as can be used for a road restraint system, are shown. The concrete wall element 1 has support elements 2 along its two longitudinal sides. The support elements 2 extend in this embodiment over the entire length of the concrete wall element 1. In other embodiments, the support elements 2 extend over only a portion of the length of the concrete wall element 1, wherein it may also be that a plurality of support elements 2 Longitudinal side of the concrete wall element 1 are arranged.

In Fig. 4, sind die Stirnseiten 11 benachbarter Beton-Wandelemente 1, die mittels Klammerelementen 5 verbunden sind, im Schnitt dargestellt. In Fig. 5 ist die Stirnansicht eines der Beton-Wandelemente 1 gemäß Fig. 4 dargestellt, wobei die Klammerelemente 5 geschnitten sind. Die Klammerelemente 5 weisen im wesentlichen ein U-Profil auf und erstrecken sich jeweils über einen Bereich der Stirnseiten 11 beider Beton-Wandelemente 1. Durch diese Ausbildung verhindern sie die Ausbildung einer Knickstelle an der Stoßstelle der benachbarten Beton-Wandelemente 1. Zur Versteifung der Klammerelemente 5 ist im Bereich zwischen den Beton-Wandelementen 1 ein Quersteg 54 angebracht. Die Klammerelemente 5 und die Beton-Wandelemente 1 weisen Bohrungen 51, 52 auf, wodurch sie mittels Befestigungselementen 53 verbindbar sind. Für eine lösbare Verbindung erscheinen insbesondere Schrauben 53 vorteilhaft zu sein. Die Bohrungen 52 des Beton-Wandelementes 1 sind durch eine Zusatzbewehrung 55 verstärkt, die mit der Bewehrung 16 verbunden ist.In Fig. 4 , The end faces 11 of adjacent concrete wall elements 1, which are connected by means of clamping elements 5, shown in section. In Fig. 5 is the front view of one of the concrete wall elements 1 according to Fig. 4 shown, wherein the clamping elements 5 are cut. The clip elements 5 have essentially a U-profile and each extend over a region of the end faces 11 of both concrete wall elements 1. By this training, they prevent the formation of a kink at the joint of the adjacent concrete wall elements 1. To stiffen the clip elements 5, a cross bar 54 is mounted in the area between the concrete wall elements 1. The clamp elements 5 and the concrete wall elements 1 have bores 51, 52, whereby they can be connected by means of fastening elements 53. For a detachable connection, in particular screws 53 appear to be advantageous. The holes 52 of the concrete wall element 1 are reinforced by an additional reinforcement 55, which is connected to the reinforcement 16.

Über die Länge des Klammerelementes 5 sind gemäß der gezeigten Ausführungsform keine Abstützelemente 2 vorgesehen. Ist nur an einer Seite der Beton-Wandelemente 1 eine Fahrbahn und ist daher nur von einer Seite mit einem Aufprall auf das Beton-Wandelement 1 zu rechnen, so können die Klammerelemente 5 ein L-Profil aufweisen, wobei die der Fahrbahn zugewandte Seite des Beton-Wandelementes 1 keine Ausnehmungen od. dgl. für das Klammerelement 5 aufweisen muß und über seine gesamte Länge ein Abstützelement 2 aufweisen kann.Over the length of the clamp element 5 no support elements 2 are provided according to the embodiment shown. Is only on one side of the concrete wall elements 1 a roadway and is therefore only on one side with an impact on the concrete wall element 1 to be expected, the clip elements 5 may have an L-profile, wherein the road side facing the concrete Wall element 1 no recesses od. Like. Must have for the clip element 5 and over its entire length a support element 2 may have.

Die Klammerelemente 5 können zur Reduktion der Gefahr der Ausbildung einer Knickstelle im Bereich der Stoßstelle benachbarter Beton-Wandelemente 1 einer Leitwand nicht nur bei Beton-Wandelementen 1 mit Abstützelementen 2, sondern bei einer Vielzahl verschiedener Beton-Wandelemente 1 verwendet werden.The clip elements 5 can be used to reduce the risk of forming a kink in the joint of adjacent concrete wall elements 1 a baffle not only in concrete wall elements 1 with support elements 2, but in a variety of concrete wall elements 1.

Die Beton-Wandelemente 1 weisen gegenüber den Klammerelementen 5 ein Spiel auf. Dadurch können sich die Beton-Wandelemente 1 bei einem Aufprall mit geringer bis mittlerer Energie (z.B. durch einen PKW) ungehindert verschieben und so die Wucht des Aufpralls abfangen, hingegen bei einem Aufprall mit hoher Energie (z.B. LKW) wird die Bewegung der Beton-Wandelemente 1 durch die Klammerelemente 5 begrenzt, sodass der Gegenverkehrsbereich nicht gefährdet werden kann. Diese Ausführung ermöglicht es somit, die Vorteile einer nachgiebigen Leitwand mit den Erfordernissen einer sicheren Rückhaltewirkung bei einer Begrenzung der Auslenkung der Leitwand zu verbinden.The concrete wall elements 1 have over the clip elements 5 on a game. As a result, the concrete wall elements 1 can move unhindered in an impact with low to medium energy (eg by a car) and thus absorb the force of impact, whereas in a high energy impact (eg trucks), the movement of the concrete wall elements 1 limited by the clip elements 5, so that the oncoming traffic can not be compromised. This embodiment thus makes it possible to combine the advantages of a resilient baffle with the requirements of a secure retention effect in limiting the deflection of the baffle.

Zum Schutz vor Beschädigungen des Beton-Wandelementes 1 können diese auf der Stirnseite 11 Schutzbleche 58 aufweisen, die mittels Ankerelementen 59 im Beton-Wandelement 1 verankert sind.To protect against damage to the concrete wall element 1, these may have on the front side 11 fenders 58, which are anchored by means of anchor elements 59 in the concrete wall element 1.

Die erfindungsgemäßen Beton-Wandelemente 1 eignen sich insbesondere zur Absicherung von Verkehrswegen durch die Ausbildung von Leitwänden, welche eine nur geringe Breite und/oder einen geringen zulässigen Verschiebungsweg aufweisen, wodurch sie insbesondere in Baustellenbereichen oder auf Brücken verwendet werden können.The concrete wall elements 1 according to the invention are particularly suitable for securing traffic routes by the formation of baffles, which have only a small width and / or a small permissible displacement path, whereby they can be used in particular in construction areas or on bridges.
