Prestressed floor with hollow floor slabs

摘要

The method for the manufacture of a prestressed flat slab floor (1) involves the laying of a number of cored floor slabs (2,3) in a X-Y modular grid. The one side of the cored floor slabs in each case is integrated in a prestressed girder section (4,5) manufactured from in-situ concrete. The unstressed reinforced cored floor slabs has an additional prestressed reinforcement extending in the vertical direction. For the prestressed reinforcement a tensioning cable is laid in the gap (32) between the abutting cored floor slabs. An independent claim is included for a prestressed flat slab floor with cored floor slabs laid in a X-Y modular grid.
