Plate of the formwork is not necessary for a floor in concrete serving as a finishing coating for the smooth ceilings

摘要

The present invention is a plate of the casing (1) formed with a plurality of similar plates to form a disposable formwork is used for the production of the floors of reinforced concrete poured in situ in the field of construction, and the - face (fig. 4) is used as a coating of the ceiling ready to be painted to the lower level. The device consists in using the plates of the formwork as a support for finishing, ceilings, with a smooth. The plates are nested and flush with the aid of bouvetages on the edges (2 and 3) and their lower face (fig. 4) is coated with an undercoat layer which is ready to receive the layer of finishing paint. The junction of the plates is processed by a strip to cracking and a coating which is adapted to the material applied in several layer by virtue of the tapered edge (5) present on the four edges of the plates. The fastening of the plates to the concrete slab and above - quality is ensured by the grooves (4) having a form of hooks, which makes it possible to fix the plate with the hardened concrete. The present invention provides a practical solution to problems of safety, in terms of ergonomics and of quality that it is found in the prior art method using plates of shuttering décoffrables and reusable.
