PLASTIC SYSTEMS FOR THE BUILDING INDUSTRY

TotiTOTI is a disposable recycled polypropylene formwork used as a modular element for the creation of foundation rafts and one-way or two-way slabs made of reinforced concrete.

TOTI is produced withrecycled plastic materialresulting from plastic scrap

post-consumer and industrial waste. The use of recycled materials saves a lot of emission, just think that for every kg of recycled plastic saves 1.5 kg of CO2.

Features and AdvantagesTOTI is a disposable recycled polypropylene formwork used as a modular element for the creation of foundation rafts and slabs made of reinforced concrete.

TOTI can be used single or double, by fitting two elements together. The side tabs allow the elements to be attached to the desired centre distance.

It can be used in the thickness of the floor with only the upper cap or, with the help of the tapered feet, floors can be made with top and bottom plates of reinforced concrete in various thicknesses.

By immersing the TOTI formworks in the concrete casting, a lattice of mutually orthogonal beams which are closed above and below by a flat plate is created. This will identify resistant “T” sections in the case of the top plate and “I” sections in the case of the top and bottom plate.

In the case of a double plate, there are two concrete laying phases to be carried out one after the other, to avoid the floating of the elements due to the counter-pressure of the self-compacting liquid concrete.

This solution of relief is highly competitive in structural solutions that necessitate a bidirectional plate behaviour and the ribs identified by the position of these products form a lattice of beams of the same geometry that greatly reduces stresses and strains. Furthermore, to simplify the reinforcement in the floor edge areas, by the pillars or walls, concrete filled areas are provided for to contrast negative moment stresses and shear stresses. In such a way, large span floors can be made which can withstand heavy loads while using smaller quantities of concrete and steel.

TOTI is available in the following sizes:- SINGLE: 16 - 20 - 25 - 30 cm- DOUBLE: 32 - 36 - 40 - 41 - 45 - 46 - 50 - 55 - 60 cm.

RAFT FOUNDATIONS: Used for the creation of raft foundations, TOTI enables a saving of concrete compared with the filled “plates” of same static performance. It is advantageous compared with plinth solutions as connecting beams between foundations and even flooring (replaced by TOTI itself) are no longer necessary.

TotiAdvantages• It enables building one-way or two-way floors.• Reduction of floor thickness.• Up to 40% reduction of the weight and consequent load

reduction on the foundations.• Reduction in the consumption of concrete and steel.• Reduction of the number and section of the pillars.• It does not require beams between the pillars, as it has a very similar

behaviour to that of the plate and a perimeter curb is usually sufficient.• Greater static performance and floors with greater spans (up to 20 metres).• Antiseismic: reduction of the seismic mass of the floor system.• Quick and easy to lay.• It can be walked on during construction (it supports a concentrated load > 200 kg).• Stackable and modular (the tapered feet are removable and easily replaced).• Architectural flexibility.

Applications• Civil and residential buildings• Offices, commercial and industrial buildings• School buildings• Hospitals• Car parks• Civil and industrial renovations

Antiseismic buildingsFLOORS and RAFT FOUNDATIONS made with the TOTI disposable formwork comply with the provisions of the new Technical Construction Standards (DM14/01/2008).FLOORS: The floors meet all general requirements for structures in reinforced concrete and those specific to floors (§ 4.1.9.2 for floors fully laid on site and § 4.1.9.3 for those which are partially prefabricated). Enable the design of floors with the necessary characteristics of ductility and deformation capacity, with good possibilities for the redistribution of seismic actions and rigidity in the plane.RAFT FOUNDATIONS: thanks to the excellent static performance, it helps overcome the limits and complications related to the isolated foundations required in earthquake zones. Indeed, the new law requires the necessity of connection between the plinths, whether in the case of superficial or deep foundations (moreover, the connection must be achieved at a distance of not over 1m from the laying level of the foundation plinth).

Laying methodTOTI can be laid single or double; without elevator feet, resting directly on the floor system, in the case of only the upper cap being present, or with elevator feet in the case of upper and lower caps being present.

If the double TOTI is used, two formworks must be coupled together. The assembly is quick and easy and the coupling system ensures a watertight seal.

• Creation of the formwork system of the floor soffit, either with traditional systems or with systems with early form stripping.

• Creation of lower reinforcement.

• Installation of TOTI formworks (there is no specific direction for installation).

• Coupling the formworks to each other at the desired distance using side tabs.

• Creation of upper reinforcement.

• Concrete casting and vibration (two laying phases are necessary, one after the other. The first layer should completely immerse the tapered feet to prevent the floating of the elements due to a counter-pressure of the concrete.

Once the concrete begins to take hold and lose fluidity, the final laying can be carried out).

• Levelling of the concrete layer.
