Abstract

Die Erfindung betrifft eine Betonbrücke mit einem als Kastenträger ausgebildeten Tragkörper (6, 7, 8), welcher mittels im Inneren des Kastenträgers vorgesehenen freiliegenden Abspannungen (14 bis 20) vorgespannt ist, wobei zumindest jeweils ein Ende der Abspannungen (14 bis 20) an innerhalb des Tragkörpers (6, 7, 8) mit diesem fest verbundenen Lisenen (11) befestigt ist. In einem oder mehreren Bereichen der Brücke sind mehrere Abspannungen (14 bis 17) in einem Fixier-und/oder Führungsbereich (9) innerhalb des betreffenden Bereichs der Brücke im Wesentlichen nebeneinander angeordnet. Dabei weist die überwiegende Anzahl der Abspannungen (14 bis 17) mit zunehmendem Abstand von einer der äußeren Seitenwände (8) des Tragkörpers jeweils eine größere Länge zwischen dem Fixier-und/oder Führungsbereich (9) und dem betreffenden Ende der Abspannungen auf als die jeweils in Richtung der betreffenden Seitenwand (8) benachbarte Abspannung. Die Lisenen (11) zur Befestigung der Enden der Abspannungen (14 bis 17) sind mit der betreffenden Seitenwand (8) verbunden oder zumindest nahe der betreffenden Seitenwand angeordnet.

Figure 00000001
The invention relates to a concrete bridge with a support body (6, 7, 8) designed as a box girder, which is prestressed by means of exposed guy lines (14 to 20) provided inside the box girder, at least one end of the guy lines (14 to 20) being inside of the supporting body (6, 7, 8) is fixed to this fixed pilaster strip (11). In one or more areas of the bridge, a plurality of guy lines (14 to 17) are arranged essentially next to one another in a fixing and / or guide area (9) within the relevant area of the bridge. The greater the number of guy lines (14 to 17), the greater the distance from one of the outer side walls (8) of the supporting body, is each of a greater length between the fixing and / or guide area (9) and the relevant end of the guy lines than each Bracing adjacent in the direction of the relevant side wall (8). The pilaster strips (11) for fastening the ends of the guy lines (14 to 17) are connected to the relevant side wall (8) or at least arranged close to the relevant side wall.
