Bridge and method for building a bridge

A bridge which is designed as a multi-span bridge having two or more spans, the bridge comprising a bridge superstructure comprising:

• two or more bridge superstructure sections each of which traverse one span of the multi-span bridge, each of the two or more bridge superstructure sections comprising,
• a plurality of longitudinal beams which are arranged adjacent to one another transversely with respect to their longitudinal direction, each of the plurality of longitudinal beams comprising a main beam section and anchor blocks which are arranged laterally on the main beam section, and
• transverse beams which are configured to connect the plurality of longitudinal beams to one another, the transverse beams being created using in-situ concrete, the transverse beams comprising a central transverse beam,
• wherein,
• two bridge superstructure sections which are arranged one behind the other in a longitudinal direction are connected by the central transverse beam which is arranged therebetween;
• and
• at least one prestressing tendon which is configured to brace two of the bridge superstructure sections which are arranged directly one behind the other in the longitudinal direction against one another, the at least one prestressing tendon being fixed to at least one of the anchor blocks.

A method for erecting a bridge which is designed as a multi-span bridge having at least two spans, the bridge comprising a bridge superstructure comprising two or more bridge superstructure sections each of which each traverse one span of the multi-span bridge, the method comprising:

• providing longitudinal beams each of which comprise a main beam section, anchor blocks which are arranged laterally on the main beam section, and cladding tubes for prestressing tendons;
• providing transverse beams which are configured to connect the plurality of longitudinal beams to one another, the transverse beams being created using in-situ concrete;
• positioning the longitudinal beams adjacent with respect to one another transversely with respect to their longitudinal direction;
• connecting mutually adjacent longitudinal beams to one another in respective end regions via the transverse beams;
• supplementing the cladding tubes for the prestressing tendons to traverse one or more bridge piers;
• connecting two bridge superstructure sections which are arranged directly one behind the other in the longitudinal direction on the bridge substructure via a central transverse beam which is created via in-situ concrete, wherein the cladding tubes are arranged to emerge upwardly from the longitudinal beam adjacent to a region in which the central transverse beam is created using the in-situ concrete;
• guiding the prestressing tendons through the cladding tubes after the central transverse beam has been created using the in-situ concrete;
• bracing at least the bridge superstructure sections which are arranged directly one behind the other in the longitudinal direction against one another via the prestressing tendons;
• and
• fixing at least one of the prestressing tendons to one of the anchor blocks.
