Ceiling slab, has filling materials made from porous concrete, and cross beam arranged in quarter points related to longitudinal direction, where concrete slab is designed as porous concrete composite slab

摘要

The slab has filling materials made from porous concrete (2), and a cross beam (7) arranged in quarter points related to a longitudinal direction. The filling materials are arranged between truss reinforced ferroconcrete beams, and a circular beam is integrated into ceiling components in prefabrication. The ceiling components are deformed among each other with turnbuckles, where the slab is designed as a porous concrete composite slab. The filling materials are inserted into freshly mixed concrete of a concrete reflector (3).
