Description

Spannbetonbrücke mit 2 Hauptträgern und orthotroper Fahrbahnplatte Die Erfindung betrifft eine Spannbetonbrücke, die ebenso wie beim Hauptpatent zwei Hauptträger aufweist und über mehrere Öffnungen durchläuft, und die außerhalb der Endquerschnitte nur aus den Hauptträgern und der Fahrbahnplatte besteht. Der Zusatzorfindung liegt die Aufgabe zugrunde, eine Spannbetonbrücke der eingangs genannten Art zu schaffen, die geeignet ist, noch größere Stützweiten als bisher zu überbrücken.Prestressed concrete bridge with 2 main girders and orthotropic deck slab The invention relates to a prestressed concrete bridge, which as in the main patent two Has main beam and passes through several openings, and the outside of the End cross-sections consists only of the main girders and the deck. The additional arrangement The underlying task is to create a prestressed concrete bridge of the type mentioned at the beginning create that is suitable for bridging even larger spans than before.

Zu diesem Zweck wird die bei X der >en beschriebenen Konstruktion relativ sehr dicke Fahrbahntafel durch eine weniger schwere Fahrbahntafel aus Beton in orthotroper Bauweise ersetzt. Anstelle der isotropen Platte beim Hauptpatent tritt eine orthotrope Platte. Diese wird gebildet aus der Fahrbahnplatte, der man zwechmäßigerweise minimale Abmessungen gibt, und den Brückenquerrippen als Hauptträger der orthotropen Platte. Die Brückenquerrippen werden in beliebiger, zweckmäßigerweise aber in engen Abständen angeordnet, sie haben beliebige Höhe. Man wird die Höhe zweckmäßigerweise jedoch nicht so hoch wie diejenige der Hauptträger wählen.For this purpose, the construction described under X is used relatively very thick pavement slab due to a less heavy concrete pavement slab replaced in orthotropic construction. Instead of the isotropic plate in the main patent occurs an orthotropic plate. This is formed from the deck slab, which one There are appropriately minimal dimensions, and the bridge transverse ribs as the main girder the orthotropic plate. The bridge cross ribs are in any, expedient but closely spaced, they have any height. One becomes the height expediently, however, not as high as that of the main beam.

Die Fahrbahnplatte sowohl wie die Brückenquerrippen werden vorgespannt.The deck as well as the bridge cross ribs are pre-stressed.

In Abb. 1 ist der Querschnitt, in Abb. 2 ein Stück des Längsschnittes der Brücke nach der Erfindung dargestellt. In den Abbildungen sind in # die Hauptträger, # die Fahrbahnplatte, # die Rippen der Brückenquerträger der orthotropen Platte, # die Punktkipplager und # die Pfeiler dargestellt.In Fig. 1 the cross section, in Fig. 2 a piece of the longitudinal section shown the bridge according to the invention. In the figures, # are the main beams, # the carriageway slab, # the ribs of the bridge cross girders of the orthotropic slab, # the point tilting bearings and # the pillars are shown.
