PREFABRICATED STAIRS PELDAÑEADA OF CONCRETE CONCRETE LIGHTED WITH EXPANDED POLYSTYRENE AND REINFORCED WITH ANGULAR.

摘要

Prefabricated staircase made of reinforced concrete lightened with expanded polystyrene and reinforced with angles. Prefabricated staircase volumetrically solid but lightened, easy to handle, cheaper price and easy to adapt to different projects, with two parallel reinforced concrete stringed beams that at the top have concrete steps of the same width as the beams, said rungs being joined by angles arranged transversely and fixed to these rungs of the beams, and under which and between the stringers beams are styrofoam blocks, the assembly being ready to receive the screed above and the plaster of plaster underneath and on the sides, directly without construction fillings or false ceilings. The beam can additionally have transverse joints at the bottom, and the highest and lowest part of the beams at their supports can be joined by transverse secondary strips. It is applicable to stairs with compensated rung.
