Description

Die Erfindung betrifft ein Trennelement für Verkehrsflächen, das bevorzugt aus Beton hergestellt ist.The invention relates to a separating element for traffic areas, which is preferably made of concrete.

Ein derartiges Trennelement ist beispielsweise aus der CH 443387 A und der EP 1 467028 A bekannt. Die dort beschriebenen Verbindungseinrichtungen weisen allerdings ebenso wie viele andere bekannte Verbindungseinrichtungen den Nachteil auf, dass sie keine ausreichende Sicherheit gegen ein Auseinanderreißen bieten. Der Grund liegt darin, dass die Verbindungselemente bzw. der Schenkel an Keilflächen aneinander anliegen, die so angeordnet sind, dass die Schenkel der Verbindungselemente auseinander gedrückt werden, wenn durch eine Kollision eines Fahrzeuges mit den über eine Verbindungseinrichtung miteinander verbundenen Trennelementen eine Kraft wirkt, welche die Verbindungselemente auseinander zieht. Die Schenkel werden zwar in einigen Konstruktionsvarianten wenigstens teilweise von Beton seitlich gestützt, um das Wegbiegen eines Schenkels zu verhindern, was aber tatsächlich nur einem sehr geringen Ausmaß möglich ist, da der Beton in diesem Eckbereich sehr leicht ausbricht.Such a separator is for example from the CH 443387 A and the EP 1 467028 A known. However, the connecting devices described there have, like many other known connection devices the disadvantage that they do not provide sufficient security against tearing apart. The reason is that the connecting elements or the leg abut against each other on wedge surfaces, which are arranged so that the legs of the connecting elements are pressed apart, when acting by a collision of a vehicle with the interconnected via a connecting means separating elements, a force pulls the fasteners apart. Although the legs are supported in some construction variants at least partially laterally by concrete to prevent the bending away of a leg, but this is actually possible only to a very small extent, since the concrete breaks out very easily in this corner.

Aus der EP 0 641 893 A und der DE 10 2007 006 746 A sind Trennelemente mit hackenförmig ineinander greifenden Verbindungselementen bekannt.From the EP 0 641 893 A and the DE 10 2007 006 746 A separators are known with chop-shaped interlocking fasteners.

Der Erfindung liegt daher die Aufgabe zu Grunde, ein Trennelement zu schaffen, bei dem die Gefahr des Auseinanderreißens bei einer Fahrzeugkollision geringer ist.The invention is therefore based on the object to provide a separating element in which the risk of tearing apart in a vehicle collision is lower.

Bei einem Trennelement der eingangs genannten Art wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst.In a separating element of the type mentioned, this object is achieved by the features of claim 1.

Durch die erfindungsgemäß ausgeführte Verbindungseinrichtung wird erreicht, dass die Schenkel durch den hakenförmig gestalteten Verbindungsbereich bei einer auf die Verbindungselemente wirkenden Zugkraft nicht auseinander gedrückt sondern im Gegenteil aneinander gehalten oder zueinander gezogen werden. Dies bewirkt in weiterer Folge, dass die auf die Schenkel wirkenden Biegemomente geringer sind, wodurch die Schenkel nicht so massiv wie im Stand der Technik ausgeführt werden müssen. Vielmehr wirken nun auf die Vorsprünge Biegekräfte, welche aber mit wesentlich geringerem Materialaufwand aufgenommen werden können, da die Biegemomente durch die wesentlich kürzeren Vorsprünge wesentlich geringer sind. Außerdem treten im Bereich der Vorsprünge Scherkräfte auf, welche ebenfalls viel leichter beherrschbar sind als die im Stand der Technik auf die Schenkel wirkenden großen Biegemomente.By means of the connecting device according to the invention, it is achieved that the legs are not pressed apart by the hook-shaped connection region when the tensile force acts on the connecting elements, but on the contrary they are held against each other or pulled towards each other. As a result, this causes the bending moments acting on the legs to be smaller, as a result of which the legs do not have to be made as solid as in the prior art. Rather, acting on the projections now bending forces, but which can be absorbed with much less material, since the bending moments are much lower due to the much shorter projections. In addition, shear forces occur in the region of the projections, which are also much easier to control than the large bending moments acting on the legs in the prior art.

Bevorzugte Ausführungsformen der erfindungsgemäßen Verbindungseinrichtung sind Gegenstand der Unteransprüche.Preferred embodiments of the connecting device according to the invention are the subject of the subclaims.

Weitere Merkmale und Vorteile der erfindungsgemäßen Verbindungseinrichtung und der erfindungsgemäßen Trennelemente ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsformen der Erfindung.Further features and advantages of the connecting device according to the invention and the separating elements according to the invention will become apparent from the following description of preferred embodiments of the invention.

In Fig. 1 ist ein erfindungsgemäßes Trennelement 1 dargestellt, das wie an sich bekannt mit weiteren Trennelementen 1 zum Trennen von Verkehrsflächen, beispielsweise Fahrbahnen von Straßen, aber auch beliebigen anderen Flächen verwendet werden kann. Wenn mehrere nebeneinander angeordnete Trennelemente 1 miteinander verbunden werden, können sie auch als Rückhaltesysteme, entweder zwischen Fahrbahnen oder am Straßenrand verwendet werden.In Fig. 1 an inventive separation element 1 is shown, which can be used as known per se with other separating elements 1 for separating traffic areas, such as roads, but also any other surfaces. If a plurality of juxtaposed separators 1 are connected together, they can also be used as restraint systems, either between lanes or at the roadside.

Zum Verbinden von nebeneinander angeordneten Trennelementen 1 wird eine erfindungsgemäße Verbindungseinrichtung 2 verwendet, welche in der in den Fig. 1 bis 4 dargestellten Ausführungsform aus zwei identischen Verbindungselementen 3 besteht. Diese Verbindungselemente 3 sind an Stirnflächen 4 der Trennelemente 1 angeordnet, wobei die an gegenüber liegenden Stirnflächen 4 angeordneten Verbindungselemente 3 um eine horizontale Achse um 180° verdreht sind, so dass sie die in Fig. 3 dargestellte Lage einnehmen.For connecting juxtaposed separating elements 1, a connecting device 2 according to the invention is used, which in the in the Fig. 1 to 4 illustrated embodiment consists of two identical connecting elements 3. These connecting elements 3 are arranged on end faces 4 of the separating elements 1, wherein the arranged at opposite end faces 4 connecting elements 3 are rotated about a horizontal axis by 180 °, so that they are in Fig. 3 take the position shown.

Die in den Fig. 1 bis 4 dargestellten Verbindungselemente 3 weisen zwei Schenkel 5 und 6 auf, die über einen Steg 7 mit einer plattenförmigen Halterung 8 verbunden sind. Ein Schenkel 5 weist an seinem von der Halterung 8 abgewandten Ende zwei Vorsprünge 9 und 10 auf, so dass eine insgesamt etwa T-förmige Querschnittsform entsteht. Der zweite Schenkel 6 weist an seinem von der Halterung 8 abgewandten Ende nur einen Vorsprung 11 auf, der zum anderen Schenkel 5 hin gewandt ist, so dass der Schenkel 6 mit seinem Vorsprung 11 insgesamt eine etwa L-förmige Querschnittsform aufweist.The in the Fig. 1 to 4 shown connecting elements 3 have two legs 5 and 6, which are connected via a web 7 with a plate-shaped holder 8. A leg 5 has at its end remote from the bracket 8 two projections 9 and 10, so that a total of approximately T-shaped cross-sectional shape is formed. The second leg 6 has at its end facing away from the holder 8 only one projection 11 which is turned to the other leg 5 out, so that the leg 6 with its projection 11 has a total of approximately L-shaped cross-sectional shape.

Die Vorsprünge 9, 10 und 11 weisen zur Halterung 8 gerichtete Kontaktflächen 12, 13, 14 auf, die in einem Winkel α kleiner 90° zu einer Mittelebene 17 der Halterung 8 ausgerichtet sind. Bevorzugt liegt Winkel α zwischen 60° und 95°, idealerweise zwischen 80° und 90°. Auf diese Weise sind die Vorsprünge 9, 10, 11 hakenartig an den Schenkeln 5, 6 angeordnet.The projections 9, 10 and 11 have to the holder 8 directed contact surfaces 12, 13, 14, which are aligned at an angle α less than 90 ° to a center plane 17 of the holder 8. Preferably, angle α is between 60 ° and 95 °, ideally between 80 ° and 90 °. In this way, the projections 9, 10, 11 are hook-like arranged on the legs 5, 6.

Werden, wie in Fig. 3 dargestellt, zwei Verbindungselemente 3 formschlüssig ineinander gesteckt, dann verhaken sich die Schenkel 5, 6 mit ihren Vorsprüngen 9, 10, 11 ineinander. Trifft ein Fahrzeug beispielsweise in der durch den Pfeil 15 symbolisierten Richtung auf ein Trennelement 1, dann verschieben sich die mit Hilfe der Verbindungseinrichtung 2 miteinander verbundenen Trennelemente 1 zunächst so weit, dass sie im Bereich ihrer Ecken 16 aneinander anstoßen. In weiterer Folge stellen die beiden Ecken 16 einen Drehpunkt dar, um den sich die Trennelemente 1 drehen wollen, wenn die durch das Fahrzeug aufgebrachte Kollisionskraft noch weiter auf eines der beiden Trennelemente 1 wirkt. Dadurch wird die Verbindungseinrichtung 2 durch eine Zugkraft belastet, welche hauptsächlich in Richtung der Ebene 17, in der die Halterung 8 liegt, auf die Verbindungseinrichtung 2 wirkt. Diese Zugkraft versucht, die Schenkel 5 der Verbindungselemente 3 zwischen den Schenkeln 5 und 6 des jeweils anderen Verbindungselementes 3 heraus zu ziehen. Dazu müssen die Schenkel 5, 6 zur Seite gebogen werden, wobei gleichzeitig die Übergänge zwischen den Vorsprüngen 9, 10, 11 und den Schenkeln 5, 6 einer kombinierten Biege- und Scherkraft ausgesetzt werden. Da die Kontaktflächen 12, 13, 14 in einem Winkel kleiner 90° zur Zugrichtung geneigt sind, verhaken die Schenkel 5, 6 mit ihren Vorsprüngen 9, 10, 11 ineinander, so dass ein größeres Biegemoment auf die Schenkel 5, 6 erst auftritt, wenn die Vorsprünge 9, 10, 11 so weit verformt wurden, dass der Winkel α der Kontaktfläche 12, 13,14 gleich oder größer 90° geworden ist.Be as in Fig. 3 shown, two connecting elements 3 positively inserted into one another, then the legs 5, 6 hooked with their projections 9, 10, 11 into each other. If a vehicle encounters a separating element 1, for example, in the direction symbolized by the arrow 15, the separating elements 1 connected to one another with the aid of the connecting device 2 initially move so far that they abut one another in the region of their corners 16. Subsequently, the two corners 16 constitute a pivot point about which the separating elements 1 want to rotate when the collision force applied by the vehicle acts even more on one of the two separating elements 1. As a result, the connecting device 2 is loaded by a tensile force, which acts mainly on the connecting device 2 in the direction of the plane 17 in which the holder 8 lies. This tensile force tries to pull the legs 5 of the connecting elements 3 between the legs 5 and 6 of the other connecting element 3 out. For this purpose, the legs 5, 6 must be bent to the side, at the same time the transitions between the projections 9, 10, 11 and the legs 5, 6 are subjected to a combined bending and shearing force. Since the contact surfaces 12, 13, 14 are inclined at an angle of less than 90 ° to the pulling direction, the legs 5, 6 engage with their projections 9, 10, 11 into one another, so that a larger bending moment on the legs 5, 6 occurs only when the projections 9, 10, 11 so were deformed far that the angle α of the contact surface 12, 13,14 has become equal to or greater than 90 °.

Da die Schenkel 5, 6 mit ihren Vorsprüngen 9, 10, 11 sehr massiv ausgeführt werden können (bei gleichzeitig relativ geringem Materialeinsatz aufgrund der geringen Länge der Schenkel 5, 6 und der Vorsprünge 9, 10, 11), kann ein maßgeblicher Teil der Verformungskraft und Verformungsenergie bereits von den Vorsprüngen 9, 10, 11 bzw. deren Verbindung mit den Schenkeln 5, 6 aufgenommen werden, noch bevor die Schenkel 5, 6 nennenswert verbogen werden. Da die Schenkel 5, 6, wie die Zeichnungen zeigen, ebenfalls relativ kurz und bei gleichzeitig relativ geringem Materialeinsatz massiv ausgeführt werden können, weisen auch diese einen sehr hohen Biegewiderstand auf und sind in der Lage, hohe Querkräfte aufzunehmen.Since the legs 5, 6 with their projections 9, 10, 11 can be performed very solid (at the same time relatively low use of material due to the small length of the legs 5, 6 and the projections 9, 10, 11), can be a significant part of the deformation force and deformation energy already from the projections 9, 10, 11 and their connection with the legs 5, 6 are taken before the legs 5, 6 are bent significantly. Since the legs 5, 6, as the drawings show, can also be made relatively short and at the same time relatively low use of material massive, these also have a very high bending resistance and are able to absorb high lateral forces.

Zusammenfassend wird durch diese Konstruktion der Verbindungselemente 3 eine Verbindungseinrichtung 2 geschaffen, die einen sehr hohen Widerstand gegen ein Auseinanderziehen der Verbindungselemente 3 im Falle eines Aufpralls eines Fahrzeuges aufweist.In summary, this construction of the connecting elements 3, a connecting device 2 is provided which has a very high resistance to pulling apart of the connecting elements 3 in the event of a collision of a vehicle.

Die Halterungen 8 sind über Stege 7 mit den Schenkeln 5 und 6 verbunden. Um eine möglichst symmetrische Belastung bzw. Kraftverteilung auf die Verbindungselemente 3 wirken zu lassen, sind die Halterungen 8 so an den Stegen 7 angeordnet, dass deren Mittelebene 17 im Bereich der Kontaktflächen 13 der beiden in der Mitte der Verbindungseinrichtung 2 liegenden Schenkel 5 liegt.The brackets 8 are connected via webs 7 with the legs 5 and 6. In order to have the most symmetrical load or force distribution on the connecting elements 3, the brackets 8 are arranged on the webs 7, that the center plane 17 is in the region of the contact surfaces 13 of the two lying in the middle of the connecting device 2 leg 5.

Die Schenkel 5, 6 und deren Vorsprünge 9, 10, 11 sind mit stark abgerundeten Kanten und Ecken ausgeführt, so dass sich die Verbindungselemente 3 leicht ineinander schieben lassen. Außerdem erleichtert dies deren Herstellung und reduziert im Bereich der Ecken die mechanischen Spannungen im Fall einer Kollision eines Fahrzeuges mit einem Trennelement 1. Die Längenverhältnisse der Schenkel 5, 6 und der Vorsprünge 9, 10, 11 sind bevorzugt so gewählt, dass das Verhältnis der Länge X der Schenkel 5, 6 und der Länge Y der Vorsprünge 9, 10, 11 zwischen 0,5 und 2,0 liegt.The legs 5, 6 and their projections 9, 10, 11 are designed with strongly rounded edges and corners, so that the connecting elements 3 can easily slide into one another. In addition, this facilitates their manufacture and reduces the mechanical stresses in the region of the corners in the event of a collision of a vehicle with a separating element 1. The length ratios of the legs 5, 6 and the projections 9, 10, 11 are preferably selected such that the ratio of the length X of the legs 5, 6 and the length Y of the projections 9, 10, 11 is between 0.5 and 2.0.

Wie Fig. 1 und 4 zeigen, sind an der Oberseite 18 und der Unterseite 19 der Halterungen 8 Verbindungsstäbe 20 befestigt, vorzugsweise angeschweißt. Die Verbindungsstäbe 20 können beispielsweise aus im Bauwesen üblicherweise verwendetem Rippentorstahl hergestellt sein und ein Verbindungselement 3 an einer Stirnseite 4 eines Trennelementes 1 mit dem anderen Verbindungselement 3 an der anderen Stirnseite 4 verbinden. Es ist aber auch denkbar, dass die Verbindungsstäbe 20 nicht von einem zum anderen Verbindungselement 3 durchgehen, sondern nach einer gewissen Länge im Inneren des Trennelementes 1 enden. Diese Verbindungsstäbe 20 können natürlich auch zwei- oder mehrfach an den Seitenflächen der Halterungen 8 angeordnet sein.As Fig. 1 and 4 show, 8 connecting rods 20 are attached to the top 18 and the bottom 19 of the brackets, preferably welded. The connecting rods 20 may, for example, be made of rib-gate steel commonly used in construction and connect a connecting element 3 on one end face 4 of a separating element 1 to the other connecting element 3 on the other end face 4. But it is also conceivable that the connecting rods 20 do not pass from one to the other connecting element 3, but after a certain length in the interior of the separating element 1 ends. These connecting rods 20 can of course also two or be arranged several times on the side surfaces of the brackets 8.

Aus den Fig. 1 bis 3 ist ebenfalls ersichtlich, dass im Bereich der Verbindungselemente 3 an den Stirnseite 4 vertikale Nuten 21 verlaufen, die einen Freiraum für den Schenkel 6 des am anschließenden Trennelemente 1 angeordneten Verbindungselementes 3 schaffen.From the Fig. 1 to 3 is also seen that in the region of the connecting elements 3 on the front side 4 vertical grooves 21 extend, which provide a free space for the leg 6 of the adjoining separating elements 1 arranged connecting element 3.

In Fig. 5 ist ein Kupplungselement 22 dargestellt, bei dem zwei Verbindungselemente 3 direkt miteinander verbunden sind. Das heißt, dass sie entweder unmittelbar im Anschluss an ihre Stege 7 oder über einen kurzen Halterungsteil 8 miteinander verbunden sind. Derartige Kupplungselemente können dafür verwendet werden, einen etwas größeren Abstand zwischen zwei Trennelementen 1 zu schaffen, beispielsweise um leichter Trennelemente 1 in Kurven mit kleinerem Kurvenradius aufstellen zu können, als dies bei direkt miteinander verbundenen Trennelementen möglich wäre.In Fig. 5 a coupling element 22 is shown in which two connecting elements 3 are connected directly to each other. This means that they are connected to each other either immediately after their webs 7 or via a short support member 8. Such coupling elements can be used to provide a slightly greater distance between two separating elements 1, for example, to be able to set up lighter dividing elements 1 in curves with a smaller radius of curvature than would be possible with directly interconnected separating elements.

In den Fig. 6 und 7 ist eine weitere Ausführungsform einer erfindungsgemäßen Verbindungseinrichtung dargestellt, welche der in den Fig. 1 bis 4 dargestellten Ausführungsform ähnlich ist, wobei der zwischen den Schenkeln 5 und 6 und dem Steg 3 vorhandene Raum für die Aufnahme des Schenkels 5 mit den Vorsprüngen 10, 11 etwas größer ist, um das Einhaken der Verbindungselemente zu erleichtern. Insbesondere in Fig. 6 ist gut zu erkennen, dass der Verbindungsbereich zwischen den Vorsprüngen 10 der Schenkel 5 in Form der Kontaktflächen 13 genau in der Verlängerung der Mittelebenen 17 der Halterungen 8 liegt, wodurch eine möglichst symmetrische Belastung bzw. Kraftverteilung auf die Verbindungselemente 3 erfolgt. Außerdem liegen bei dieser bevorzugten Ausführungsform der Erfindung alle Kontaktbereiche zwischen den Flächen 12, 13, 14 der Vorsprünge 9, 10, 11 der Schenkel 5,6 in einer Ebene 38, welche im rechten Winkel zu den Ebenen 17 der Halterungen 8 liegt.In the 6 and 7 a further embodiment of a connecting device according to the invention is shown, which in the Fig. 1 to 4 illustrated embodiment is similar, wherein the existing between the legs 5 and 6 and the web 3 space for receiving the leg 5 with the projections 10, 11 is slightly larger in order to facilitate the hooking of the connecting elements. In particular in Fig. 6 is good to see that the connection region between the projections 10 of the legs 5 in the form of the contact surfaces 13 exactly in the extension of the center planes 17 of the brackets 8, whereby a possible symmetrical load or force distribution takes place on the connecting elements 3. In addition, in this preferred embodiment of the invention, all contact areas between the surfaces 12, 13, 14 of the projections 9, 10, 11 of the legs 5, 6 lie in a plane 38 which lies at right angles to the planes 17 of the holders 8.
