The floor is manufactured on the basis of filigran technology, i.e. on the bottom there is a 3-5 cm layer of concrete with hollow clay blocks or expanded clay blocks added at the precasting plant to a height of 7 cm above the hollow block bottom.

Advantages:

  • it is possible to adjust the entire geometry of precast elements to the floor plan – individual statics.
  • low assembly weight: between 1.51 and 3.03 kN/m2.
  • reduction of dead load from 25 to 40 % as compared to semi-precast filigran type floors / cast-in-situ floors
  • savings of materials used for assembly support – the first support should be 1.0 m from the wall, subsequent ones – 2.50-2,90 m – see the table.
  • steel consumption at the construction site equals ca. 30-35 % of the reinforcement used in the case of semi-precast filigran floors / cast-in-situ floors
  • the floor is constructed in time 70% shorter as compared to semi-precast filigran type floors and 80% shorter as compared to cast-in-situ floors.

total cost of the floor construction is 10-15 lower than the cost of cast-in-situ floor or semi-precast filigran type floor.

AT THE CONSTRUCTION SITE:

  • place the semi-precast elements
  • place the upper reinforcement
  • set in concrete

There is no reinforcement at the bottom of the slabs and the joints of precast elements are not reinforced – labour is reduced by 100%!!!
