Formwork and dome for hollow core slab

Aerated flooring system for heights up to 250 cm constituted by Cupolex Rialto dome, pipes and base that quickly connected the one to the other compose a structure suitable for receiving poured concrete. Cupolex Rialto is a forming system for providing an easy, efficient and fast solution for constructing an aerated floor with heights from 50 cm to 250 cm. This forming system comprises of Cupolex Rialto domes, pipes and bases that quickly interlock and connect to each other composing a self bearing structure ready for the placement of a concrete slab. The elevated Cupolex Rialto slab supported by thematrix of columns, formed by the pipes, allows thesystem for high load-bearing capacities and the elevated Cupolex Rialto structure creates a hollow space for a ventilation under the floor. The recycle ofair, that is formed below the slab, convoys the humidity and any radon gas outside the buildings. With Cupolex Rialto the living is healthier and brings benefits for the duration of the building. Cupolex Rialto is an ideal product to be used for renovation instead of using gravel material for raising the deck.

Technical data
Materials required for 1 m²
• 3 Rialto Bases;
• 3 Rialto Pipes of 125 mm in diameter;
• 3 Cupolex Rialto units;
• 0,035 m³ of concrete consumption for each linear metre of the height of the pipe;
• 0,022 m³ of concrete consumption top of dome;
• welded wire mesh type as to design specifications;
• 0,01 m³/m² of concrete for each cm of concrete above the Cupolex Rialto domes.
1. Assemble the base with the two elements as shown on picture 1;
2. connect the assembled bases in order to obtain the alignment grid;
3. assemble the bases on the prepared subbase horizontally in rows starting from left to right and top to bottom, with the arrows on the bases pointing up and to the right;
4. put the pipes into the cup of the bases till they are completely inserted;
5. place the Rialto domes on pipes horizontally in rows starting from left to right and top to bottom;
6. cut the element cupolex all along the perimeter and take care that it sits on the edge of a temporary wooden strip fixed to the foundation or perimeter wall. Check whether the Cupolex Rialto domes lean correctly against the containment walls and the dome flooring system is ready;
7. Reinforce, if necessary, part of the hanging slab with additional reinforcement placed on top of the slab;
8. Pay attention when walking on Cupolex Rialto especially along the edge.

Cupolex Rialto slab for tanks and drough-beating rainwater storage
Once optional, rainwater harvesting is now a necessity and choosing a Cupolex Rialto system is a major step in securing water for your
building site. They are discreet and do not encroach on living areas.
Cupolex Rialto slab tanks and cisterns offer drought-beating rainwater storage that’s out of sight and doesn’t take up valuable real estate. Available in almost any capacity, Cupolex Rialto slab tanks and cisterns are hidden within the slab of the building, under parking areas or beneath landscape areas, allowing you to harvest, store and use your rainwater around the home or building without restriction. Cupolex Rialto slab tanks and cisterns are economical, fast and simple to construct. Cupolex Rialto slab tanks don’t require deep holes or shoring which can be costly and messy, or cause interruptions or risk workplace safety on the building site.
Structural Resistance
Slabs structed with Cupolex Rialto have been tested in collaboration with the CNR and the University of Padova and the results implemented in the code of calculation “Easy Cupolex”. Please enquire it to our technical office, free of charge.
Walking Support
The elements Cupolex have been tested to support a load of 150 daN applied on plate of 5x5 cm set on the top of the element.
