Kypse: the hollow core slab with flat intrados and contained sections
AN INNOVVATIVE AND EFFECTIVE SOLUTION
The Kypse hollow core slab is produced in 10 models with different sections ranging from 20 cm to 44 cm, depending on whether it is used continuously or simply as a support. Kypse can withstand loads up to 5200 kg / sqm. It is made of pre-stressed beloved cement, this guarantees excellent transmission of stresses in the plane and low values of deformability due to bending.
Kypse slabs are produced by extrusion with vibrated concrete type C45 / 55 with durability class XC3, in compliance with the new Technical Standards. A mixture of water and cement is used which ensures high resistance to compression and traction, allowing the use of Kypse floors even in the presence of large spans and high overloads.
Prestressing is achieved with the use of stabilized harmonic steel strands.
Kypse panels are equipped with milling on the extrados at the supports and are reinforced with harmonic steel in pretension. This allows easy connection with the supporting structures, without the need for further works.
In summary, therefore, the technical characteristics of Kypse prefabricated floors are:
- Concrete Rck = 55 N / sq mm
- Harmonic steel in stabilized strands fptk = 1860 N / mmq, fp (1) k = 1670 N / mmq
- Concrete for additional castings Rck = 30/35 N / m
