Motorway bridge for fly-over of e.g. foot path, has super structure placed in prefabricated longitudinal supports extending in bridge longitudinal direction, and concrete slab concreted on prefabricated longitudinal supports

摘要

The bridge has a super structure placed in prefabricated longitudinal supports extending in bridge longitudinal direction. The prefabricated longitudinal supports are closely arranged next to each other transverse to the bridge longitudinal direction. A concrete slab (2) is concreted on the prefabricated longitudinal supports, where the prefabricated longitudinal supports are prestressed in longitudinal direction by using clamping elements.
