MULTISPAN GIRDER

摘要

The invention relates to a multispan girder (1) consisting of concrete, especially reinforced concrete or prestressed concrete. The multispan girder (1) is provided with bearings which are located at each end of a span of sai d girder (1). The girder (1) is produced especially from at least one precast concrete part. At least one prestressing element is located on the girder (1 ), the position, course and/or prestressing force of said prestressing element producing a non-deformable pretension of the multispan girder (1). The multispan girder (1) is preferably provided for arranging a travel way of a railborne high speed vehicle, especially a magnetic levitation train.
