Steel-concrete structure for floor slabs

摘要

The ceiling support is a steel girder (3) with local concrete part encased in concrete with the storey ceiling. To transfer bending movements between the girder and upright support (2) there is at least one tensile stressed reinforcement element (12) on one side anchored in the upright and guided through same into the adjoining ceiling girder, and on the other side embedded in the compound concrete part. Shear teeth are provided in the connecting seam between the upright and concrete part of the girder to transfer the transverse forces at least in the event of a fire. The reinforcement elements pass through tubular sleeves which have a setting material such as concrete inside.
