Formwork and dome for hollow core slab
VESPAIO 4S is an innovative system for building ventilated crawl spaces, floors and roofs and cavities in general. Is a square element 50 x 50 cm, equipped with a versatile joining system by which and element can be modularly overlapped to the next. in the heights H-35 H-40 H-45 H-50 H-55 there is a safety joint that prevents the legs from opening during casting. On each modulethere are directional arrows and an assembly diagram showing the correct direction of installation. With VESPAIO 4S a safe platform which can be walked on is created and over this the concrete is cast. VESPAIO 4S is generally installed on a foundation of lean concrete of varying thickness depending on the situation.After the laying of a suitable mesh, proceeding with the casting of concrete, many pillars are formed which, once the concrete is cured, determine the actual resistance of the floor, with the uniform distribution of loads over the entire surface. VESPAIO 4S is used in new constructions or in renovations of residential and industrial buildings. VESPAIO 4S creates a plumbing space with an appropriate steam barrier for the floor and, properly ventilated by pipes connected with the outside, a vehicle for the disposal of Radon gas.
