Consolidation of existing wooden floors
Old wooden floors often need to be strengthened and stiffened as they were designed to bear modest loads, with excessive deformation and vibration characteristics compared to current requirements.
Intervening with load-bearing concrete is an optimum solution as it allows the existing floor to be reused rather than replaced, with only a modest change in the existing floor thickness.
The interposition of dowels and crampons between the wooden beams and the concrete slab is necessary to allow the two materials to work together.
After laying the reinforcing irons we proceed with the casting of light structural pre-mixed concrete (Lecabeton type) which weighs 1,400 kg /cm on site, much lighter compared with the 2,400 kg / cm of traditional concrete.
The dynamic behaviour (vibrations), acoustic insulation and thermal inertia are thus improved.
Consolidation of existing girders and terracotta floors
The connectors are fastened to the beams with high-strength nails thanks to a special nail gun.
After laying the reinforcing irons we proceed with the casting of light structural pre-mixed concrete (Lecabeton type) which weighs 1,400 kg /mc on site, much lighter compared with the 2,400 kg /mc of traditional concrete.
This results in greater load-bearing capacity, lower total height, greater rigidity and better fire resistance.
Ditta Omnia Plastica - Busto Arsizio, Italy
Omnia Plastica is a company that produces semi-finished products and finished industrial parts. In November 2013 a fire broke out in a department causing the implosion of the prefabricated roof with no damage to third parties and people.
In a short time we were entrusted with the works that mainly consisted of:
- cladding with 4 cm thick fiber-reinforced concrete (HPFRC), effective for the reinforcement of existing damaged concrete pillars;
- creation of forks for supporting prefabricated beams, roof tiles and insulated aluminum sheet mantle new concrete flooring;
- partitioning of the spaces with fireproof Rei concrete blocks and Rei 120 plaster on the existing reinforced concrete structure with a Knauf company cycle.
