Description

Gegenstand der vorliegenden Erfindung ist ein abgestuftes Rückhaltesystem an Straßen aus Beton. Rückhaltesysteme an Straßen unterliegen der DIN EN 1317-2 vom April 1998, in der die Leistungsklassen und die Prüfverfahren festgelegt sind. Außer Rückhaltesystemen aus Metall haben sich auch solche aus Beton bewährt, wobei bisher die besten Ergebnisse erzielt werden mit solchen Rückhaltesystemen, die abgestuft sind.The subject of the present invention is a graduated restraint system Concrete streets. Restraint systems on roads are subject to DIN EN 1317-2 from April 1998, in which the performance classes and the test methods are defined are. In addition to metal restraint systems, there are also concrete ones proven, whereby the best results have been achieved with such Restraint systems that are graduated.

Rien van der Drift beschreibt in Straßenverkehrstechnik 3/99, Seiten 120 - 123, die in den Niederlanden entwickelte STEP-Schutzwand. Das Profil dieses Rückhaltesystems aus Beton weist eine untere Stufe mit circa 250 mm Höhe und einer Abweichung von der Senkrechten von circa 9 gon, eine mittlere Stufe von circa 50 mm Höhe und eine Abweichung von der Senkrechten von circa 50 gon und eine obere Stufe von circa 600 mm und eine Abweichung von der Senkrechten von circa 9 gon auf. Die obere Breite beträgt circa 200 mm. Die Gesamthöhe dieses Rückhaltesystems beträgt somit 900 mm. Dieses Rückhaltesystem ist gegenüber der New-Jersey-Schutzwand um 90 mm höher, so dass vor allen Dingen Fahrzeuge mit hoch gelegenem Schwerpunkt nicht mehr so leicht kippen können. Durch die Höhe von 90 mm wird der Lichtschein der Scheinwerfer von entgegenkommenden Fahrzeugen besser abgeschirmt. Die Testung dieser Schutzvorrichtung hat ergeben, dass sie die Anforderung H2 nach Euro Norm 1317-2 erreicht, nicht jedoch das hohe Aufhaltevermögen wie es die Aufhaltestufen H4a und H4b nach Euro Norm 1317-2 fordern.Rien van der Drift describes in traffic engineering 3/99, pages 120 - 123, the STEP protective wall developed in the Netherlands. The profile of this Restraint system made of concrete has a lower step with a height of approximately 250 mm and a deviation from the vertical of about 9 gon, a medium level of approximately 50 mm in height and a deviation from the vertical of approximately 50 gon and an upper step of approximately 600 mm and a deviation from the Vertical from about 9 gon on. The upper width is approximately 200 mm. The The total height of this restraint system is therefore 900 mm. This Restraint system is 90 mm higher than the New Jersey bulkhead, so above all, vehicles with a high center of gravity are not can tilt more easily. The light shines through the height of 90 mm the headlights are better shielded from oncoming vehicles. The Testing of this protection device has shown that it fulfills the requirement H2 achieved according to Euro Norm 1317-2, but not the high level of stamina like containment levels H4a and H4b in accordance with Euro Norm 1317-2 are required.

Die Erfindung hat sich die Aufgabe gestellt mit möglichst geringem Aufwand und möglichst wenigen Veränderungen der STEP-Schutzwand doch die Anforderung H4 zu erfüllen, d.h. auch Sattelzüge mit einer Gesamtmasse des Fahrzeugs von 38.000 kg zurückzuhalten. Dabei soll gleichzeitig das Rückhaltevermögen für leichte Pkw erhalten bleiben (TB 11 nach Euro Norm 1317-2). The invention has set itself the task with as little effort and as few changes to the STEP protective wall as possible To meet H4, i.e. also articulated lorries with a total mass of the vehicle of Withhold 38,000 kg. The retention capacity for light cars are retained (TB 11 according to Euro Norm 1317-2).

Diese Aufgabe wird jetzt gelöst durch ein Rückhaltesystem gemäß Patentanspruch, welches in Abänderung der STEP-Schutzwand eine um 200 mm höhere obere Stufe aufweist, so dass die Gesamthöhe circa 1100 mm beträgt. Durch Beibehaltung der unteren und mittlere Stufe und der Abweichungen von der Senkrechten ist gewährleistet, dass insbesondere schnellfahrende leichte Pkws weiterhin gut zurückgehalten werden. Da die obere Breite von circa 200 mm beibehalten wird, vergrößert sich die untere Breite des Fußes von 542 mm auf nur 598,6 mm. Sowohl der Raumbedarf als auch der Materialbedarf steigen somit nur unwesentlich. Dennoch hat sich gezeigt, dass die relativ geringfügige Vergrößerung bezüglich Gesamthöhe und Fußbreite zur wesentlichen Steigerung des Rückhaltevermögens führt. Während die Aufhaltestufe H2 nur die Abnahmeprüfungen TB51 und TB11 (EN 1317-2) erfüllen muss, fordert die Aufhaltestufe H4b die Abnahmeprüfung TB81. TB51 wird gefordert für Busse mit einer Gesamtmasse des Fahrzeuges von 13.000 kg, während TB81 die Rückhaltung von nahezu dem 3-fachen, nämlich 38.000 kg, fordert.This task is now solved by a restraint system according to Claim, which in modification of the STEP protective wall a by 200 mm has a higher upper step, so that the total height is approximately 1100 mm. By maintaining the lower and middle levels and the deviations from the vertical ensures that especially fast-moving light Cars continue to be held back well. Since the top width of about 200 mm is maintained, the lower width of the foot increases by 542 mm to only 598.6 mm. Both the space requirement and the material requirement increase therefore only insignificant. Nevertheless, it has been shown that the relatively minor Enlargement in terms of total height and foot width for a substantial increase of the retention capacity. While the containment level H2 only Acceptance tests TB51 and TB11 (EN 1317-2) must be met by the Holding level H4b the acceptance test TB81. TB51 is required for buses with a total mass of the vehicle of 13,000 kg, while TB81 the Restraint of almost 3 times, namely 38,000 kg, demands.

Von entscheidender Bedeutung sind bei dem erfindungsgemäßen Rückhaltesystem zum einen die spezielle Bewehrung aus 5 bis 10 in Abständen von 60 bis 100 mm ein- oder zweireihig übereinanderliegenden Reihen von endlosen Stahlstäben oder Stahlseilen mit 12 bis 16 mm Durchmesser. Diese Bewehrung ist in der Lage, auch die Energie eines Sattelzugs aufzunehmen und so zu verteilen, dass es nicht zu einem Reißen der Bewehrung oder Zerschneiden des Betons kommt. Weiterhin wird der Effekt dadurch verstärkt, dass der Fuß nicht wie bisher üblich in den Fahrbahnbelag eingebunden ist, so dass er im Falle des Anpralls sich geringfügig seitlich verschieben kann und damit weitere Energie des Aufpralls abfangen kann.Are of crucial importance in the invention Restraint system on the one hand the special reinforcement from 5 to 10 at intervals from 60 to 100 mm one or two rows of rows of endless steel rods or steel cables with a diameter of 12 to 16 mm. This Reinforcement is also able to absorb the energy of a tractor-trailer and to distribute so that there is no tearing of the reinforcement or The concrete is cut. The effect is further enhanced by that the foot is not integrated into the pavement as usual that it can move slightly sideways in the event of an impact, and so that more energy can absorb the impact.

Das erfindungsgemäße Rückhaltesystem ist dennoch im Wesentlichen starr, so dass bei ihm beim Fahrzeuganprall keine signifikanten elastischen oder bleibenden Deformationen auftreten. Die Energie wird beim Fahrzeuganprall im Wesentlichen durch die Deformation am Fahrzeug absorbiert. Ein weiterer Vorteil besteht darin, dass dieses System in Gleitschalung gefertigt werden kann und auf Schubbewehrung (Bügelbewehrung) verzichtet werden kann. Die Bewehrung durch Stahlseile oder Stahlstäbe erfolgt unmittelbar beim Betoniervorgang und führt zu einem direkten Verbund zum umgebenden Beton.The restraint system according to the invention is nevertheless essentially rigid, so that there are no significant elastic or permanent deformations occur. The energy is in the event of a vehicle impact Essentially absorbed by the deformation on the vehicle. Another The advantage is that this system can be manufactured using sliding formwork and shear reinforcement (stirrup reinforcement) can be dispensed with. The Reinforcement by steel cables or steel bars takes place immediately at Concreting process and leads to a direct bond to the surrounding concrete.

In der anliegenden Figur 1 ist eine neue und dabei bevorzugte Ausführungsform des neuen Rückhaltesystems dargestellt.In the attached Figure 1 is a new and preferred embodiment of the new restraint system.
