Prefabricated truss floor slabs are a prominent choice in lightweight prefabrication due to their construction advantages.
The truss beams for the floor slab are made of a triangular truss of B450C or B450A steel connected to clay blocks (with a base of 12 cm) by vibrated concrete with a characteristic strength of Rck≥ 30 N/mm².
The standard height truss of 12.5 cm consists of 3 bars (2 ø 5 mm lower and 1 ø 7 mm upper) connected with ø 5 mm welded stirrups.
The weight of the finished product is approximately 10 kg per metre.
Based on the span, slab height, applied loads, and constraints of the slab, additional B450C steel reinforcement is added according to the calculation results.
