Abstract
Schutzverkleidung für Leitplanken (10), in der Form eines Körpers (18; 18') aus Kunststoff, der die der Straße zugewandte Seite der Leitplanke (10) bedeckt, dadurch gekennzeichnet, dass der Körper (18, 18') einen sich in seiner Längsrichtung erstreckenden Streifen (34) mit einem Wellenprofil aufweist, dessen Wellen vertikal verlaufen.Protective covering for crash barriers (10), in the form of a plastic body (18; 18 ') covering the side of the guardrail (10) facing the road, characterized in that the body (18, 18') extends in its direction Has longitudinally extending strip (34) with a wave profile whose waves are vertical.
Description
Die Erfindung betrifft eine Schutzverkleidung für Leitplanken, in der Form eines Körpers aus Kunststoff, der die der Straße zugewandte Seite der Leitplanke bedeckt. The invention relates to a protective covering for guardrails, in the form of a body made of plastic, which covers the side of the guardrail facing the road.

Aufgabe der Erfindung ist es, die Verkehrssicherheit von Leitplanken weiter zu verbessern. The object of the invention is to improve the traffic safety of crash barriers on.
Diese Aufgabe wird bei einer Schutzverkleidung der eingangs genannten Art dadurch gelöst, dass der Körper einen sich in seiner Längsrichtung ersteckenden Steifen mit einem Wellenprofil aufweist, dessen Wellen vertikal verlaufen. This object is achieved in a protective covering of the type mentioned above in that the body has a stiffening in its longitudinal direction stiffeners with a wave profile whose waves are vertical.
Auf diesen wellenförmig profilierten Streifen kann eine flexible reflektierende Folie aufgeklebt werden, so dass ähnlich wie bei dem oben diskutierten Stand der Technik die Sichtbarkeit der Leitplanke verbessert wird. Der Vorteil besteht darin, dass das Wellenprofil nicht durch den Reflektor gebildet zu werden braucht, sondern unmittelbar durch den Kunststoffkörper gebildet wird. Dadurch wird eine wesentlich kostengünstigere Herstellung des Reflektors ermöglicht. A flexible reflective film may be adhered to these undulating profiled strips so that the visibility of the guardrail is improved, similar to the prior art discussed above. The advantage is that the wave profile does not need to be formed by the reflector, but is formed directly by the plastic body. As a result, a much cheaper production of the reflector is made possible.
Zugleich hat der wellenförmig profilierte Streifen des Kunststoffkörpers die Funktion, die Steifigkeit und Bruchfestigkeit des Kunststoffkörpers zu erhöhen. Das ist insbesondere dann von Vorteil, wenn der Kunststoffkörper nach unten zu einer als Unterfahrschutz dienenden Schürze verlängert ist. Bei einem heftigen Aufprall auf diese Schürze wird der obere, an der Leitplanke gehaltene Teil des Kunststoffkörpers sehr stark auf Dehnung und Biegung beansprucht, so dass es leicht zu einem Bruch kommen kann, mit der Folge, dass die Schürze ihre Schutzfunktion nicht mehr erfüllen kann. Bei der erfindungsgemäßen Schutzverkleidung wird diese Gefahr durch das Wellenprofil erheblich verringert. At the same time, the wavy profiled strip of the plastic body has the function of increasing the rigidity and breaking strength of the plastic body. This is particularly advantageous if the plastic body is extended down to serving as an underrun apron. In a violent impact on this apron, the upper, held on the guardrail part of the plastic body is very much subjected to stretching and bending, so that it can easily come to a break, with the result that the apron can no longer fulfill their protective function. In the protective covering according to the invention, this danger is considerably reduced by the wave profile.
Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. Advantageous embodiments and further developments of the invention are specified in the subclaims.
Der Kunststoffkörper kann beispielsweise durch ein Strangprofil gebildet werden, bei dem unmittelbar nach der Extrusion mit Hilfe einer Zahnwalze die wellenförmigen Profilierungen in den noch plastischen Kunststoff eingeprägt werden. Alternativ kann es sich bei dem Kunststoffkörper um ein Tiefziehteil handeln. The plastic body can be formed for example by an extruded profile, in which immediately after the extrusion by means of a toothed roller, the wave-shaped profilings are embossed into the still plastic plastic. Alternatively, the plastic body may be a deep-drawn part.
In einer anderen Ausführungsform besteht die Schutzverkleidung aus aufeinanderfolgenden Segmenten, die jeweils als Hohlkörper ausgebildet sind und beispielsweise im Blasformverfahren oder im Schleudergussverfahren hergestellt werden. Die einzelnen Segmente können an ihren Enden mit vertikal verlaufenden Nuten und Federn versehen sein, so dass sie sich stabil miteinander verketten lassen. In another embodiment, the protective covering consists of successive segments which are each designed as hollow bodies and are produced, for example, by blow molding or by centrifugal casting. The individual segments may be provided at their ends with vertically extending grooves and springs, so that they can be stably linked together.
Im folgenden werden Ausführungsbeispiele anhand der Zeichnung näher erläutert. In the following embodiments are explained in detail with reference to the drawing.
