Eine neue Bauweise für Verbundbrücken stellt die Brücke in Pöcking dar. Die seit einigen Jahren eingesetzte VFT ® -Bauweise und der Betondübel finden darin ihre Weiterentwicklung. Betondübel, die durch einen speziellen Trennschnitt des Walzträgers entstehen, verbinden das Betonfertigteil mit dem Stahl zu einem vorgefertigten Stahlverbundträger. Mit einem hohen Grad an Vereinheitlichung und Vorfertigung entsteht ein System mit wirtschaftlichem Materialeinsatz und sehr hoher Qualität. An der nun unter Verkehr stehenden Brücke in Pöcking werden statisch-konstruktive Details und Gesichtspunkte der Herstellung näher beleuchtet.The new road bridge over the railway line next to Pöcking applied to a new construction method for composite bridges. The VFT ® -construction method, which has been established in Germany within the last years combined with concrete dowel technology, generated a new type of prefabricated composite girders. Concrete dowels, which are manufactured by special steel web cuts connect rolled steel profiles with pre-cast concrete members. An increasing degree of standardisation and prefabrication enables the application with an economic use of resources and a high quality level. This article describes design and manufacturing aspects of the new bridge, which is already under traffic use.
