COMPLETE SYSTEM FOR BUILDING THE FLOOR

LIGHTENED IN WORK PREPARED FOR

CEILING PLATING IN PLASTERBOARD OR PLASTER

ON THE NET "

The invention is inherent in the field of construction and is related to the floor system.

On the market there are floors with beams cast in situ or prefabricated with interposed elements such as brick pignatte, various lightening elements or solid concrete slab. Floors with cast-in-situ and prefabricated joists have the disadvantage of a tiring and dangerous handling of the pignatte or prefabricated joists due to the weight, which causes the need for service bridges, long construction times and inaccuracy in positioning.

On the other hand, in floors with various lightening elements, the main drawback lies in the fixing of the latter, to prevent movement during the concrete casting.

The technical problem to be solved is to create a complete system to create a lightened slab cast on site with a reduction of at least 25% of the weight of the slab compared to traditional structures usually on the market, which guarantees resistance to noise and thermal shocks, simple and quick to assemble, economical in transport, storage and construction, which guarantees safety and stability during the concrete casting, which favors the positioning of systems and at the same time guarantees support for the finishing of the soffit of the floor in a very short time.

The invention consists in the realization of a light and modular ceiling system on site consisting of:

1 - 2.5 cm thick wooden boards hereinafter referred to as "boards / bottom" of variable width and length determined by the structural calculation, with standard center distance of 60 cm to which the reinforcements of the joists are mechanically fixed at the work site;

2 - dry-laid polystyrene panels with lightening and thermo-acoustic insulation and wedged between the "boards / base",

3 - reinforced concrete joists.

In the drawing (fig. A) which shows the cross section of the floor, you can see the fir wood planks (1), the metal brackets fixed on the wood planks (2), the reinforcement to complete the joists (3), the polystyrene lightening elements (4), the plasterboard screwed to the wooden boards or plaster-carrying mesh (5), the electro-welded mesh (6) and the concrete slabs cast on site to complete the floor (7). The components of the floor system, commonly available on the market, as designed, are delivered to the construction site on pallets

The metal brackets and reinforcements at the foot of the work are fixed to the boards / back with simple stapling or nailing to speed up the work.

These boards, completed with reinforcement, are raised and positioned on the provisional formwork which constitutes the plan orientation, normally spaced by 60 cm with appropriate crosspieces, one in correspondence with each head and one central in wood.

The interlocking polystyrene panels are inserted into the grid of the "boards / base", already complete with the reinforcement of the joists, to prevent them from moving during the casting phase.

1 polystyrene panels (Density = 15 kg / m3) have the primary function of lightening the floor (finished floor weight = 220 kg / m2), as well as good thermal and acoustic insulation due to the low density.

We then proceed with the laying of the metal mesh of the slab and with the casting of concrete.

After the decommissioning of the deck, the soffit at the intrados can accommodate electrical and mechanical systems with extreme simplicity; in particular, 1.2 cm thick plasterboard plating can be applied to the planks / base with a flush view at 60 cm distance by simply screwing onto the planks for ceiling finishing, without additional expensive and difficult to install supports, or anchored with door net stapling plaster.

This system is light, simple, cheap and fast as the assembly takes place with elements prepared to measure, any adaptations with respect to the standard steps are made through cuts on easily workable materials, such as wood and polystyrene, fast nailing of the brackets and interlocking of the polystyrene.
