Modular formwork TOTI

TOTI 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. SINGLE: 16 – 20 – 25 – 30 cm DOUBLE: 32 – 36 – 40 – 41 – 45 – 46 – 50 – 55 – 60 cm 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.
