Description
Pneumatischer wasserdichter Fahrbahnübergang für Brücken Die Erfindung betrifft einen Fahrbahnübergang für Brücken, mit welchem der Spalt zwischen Widerlager und Brücke abgedeckt wird. Solche Fahrbahnübergänge sind in mannigfaltiger Form bekannt, meist bestehen sie aus Abdeckplatten oder einem Rost. In jedem Falle snd sie ganz oder zum größten Teil aus Stahl.Pneumatic watertight deck crossing for bridges The invention relates to a road crossing for bridges, with which the gap between the abutment and bridge is covered. Such road crossings are in various forms known, they usually consist of cover plates or a grate. In any case snd all or most of them made of steel.
Bei der neuen Erfindung handelt es sich um einen starkwandigen Gummikörper. Er wird am brücken- bzw. widerlagerseitigen Ende in im Querschnitt rechteckigen Aussparungen gehalten und ist von wechselseitig an Brücke und Widerlager angeordneten Konsolen unterstützt. Im Querschnitt ist der Körper so ausgebildet, daß er sich um das gewünschte Maß zusammendrücken läßt.The new invention is a thick-walled rubber body. It is at the bridge or abutment-side end in a rectangular cross-section Recesses held and is arranged alternately on the bridge and abutment Consoles supported. In cross-section, the body is designed so that it is can be compressed to the desired extent.
Die Tragfähigkeit des Körpers wird erreicht entweder durch Verwendung eines Materials mit entsprechenden Wandstärken, welches nicht nur ausreicht, den normal erforderlichen Luftdruck, sondern auch den sich durch das Zusammendrücken vergrößernden Luftdruck auszuhalten oder der erforderliche Luftdruck wird durch ein Druckausgleichgefäß und einem berdruckventil auf die erforderliche Höhe gehalten. Darüber hinaus besteht vielleicht die Möglichkeit, mit der Brückenbewegung Luft einzudrücken oder herauszulassen.The carrying capacity of the body is achieved through either use of a material with appropriate wall thicknesses, which is not only sufficient for the normally required air pressure, but also the pressure exerted by the compression withstand increasing air pressure or the required air pressure is achieved by a pressure equalization vessel and a pressure relief valve are kept at the required height. In addition, there may be the possibility of air with the bridge movement to push in or let out.
Damit der Gummikörper sich in der höhe durch den Luftdruck nicht verändern kann, sind, falls erforderlich, die Rippen durch dünne Stahleinlagen bewehrt (Pos. 4).So that the rubber body does not change in height due to the air pressure If necessary, the ribs are reinforced with thin steel inserts (pos. 4).
Der Körper ist im Querschnitt symmetrisch ausgebildet, damit er wegen der Abnutzung durch einfaches Umdrehen beidseitig verwendet werden kann. Zusätzlici könnten die durch das tJberfahren dem Verschleiß ausgesetzten Köpfe der lippen so ausgebildet werden, daß sie leicht ausgewechselt werden können.The body is symmetrical in cross section so that it is due to wear and tear can be used on both sides by simply turning it over. Additionally The heads of the lips, which are exposed to wear as a result of being run over, could do this be designed so that they can be easily replaced.
Der !:ahrbahntibergaflg hat gegenüber allen anderen Konstruktionen nicht nur de Vorzug unkomPliziert sondern auch absolut wasserdicht und niciitrosten zu sein.The!: Ahrbahntibergaflg has a different structure than any other not only the advantage of uncomplicated but also absolutely watertight and non-rusting to be.
