PLASTIC SYSTEMS FOR THE BUILDING INDUSTRY

Top 4S TOP 4S is a disposable formwork made from recycled polypropylene suitable to create ventilated crawl spaces, cavities and floors in all types of new construction or renovation. TOP 4S is produced with recycled plastic material resulting 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 k

eaturesdvantages TOP 4S is aninnovative 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 module there are directional arrows and an assembly diagram showing the correct direction of installation. With TOP 4S a safe platform which can be walked on is created and over this the concrete is cast. TOP 4S...

Top 4S Advantages • Speed and simplicity of installation (one person can lay up to 100 square meters per hour) • It can be walked on during the work phase • Reduces labour time by 80% • Saves concrete • Adaptation for out of square areas by cutting the elements • Natural or forced ventilation across the whole surface • Passage of the systems under the floor in all directions • Ability to create the foundation beams and slab with a single casting using the FERMOplast or TELEstop accessories. Applications • Crawl spaces, ventilated crawl spaces, cavities and floors in residential and...

Laying method The joining system of the TOP 4S allows it to be installed quickly and easily. Lay the elements from top to bottom and from left to right, ending one row at a time. The two arrows on each element should be directed upwards and to the right (see picture). Execution of a ventilated crawl space • Preparation of the rolled gravel subbase. • Creation of the lean concrete subbase, of variable thickness depending on the overloads and the capacity of the ground. • Placement of the rebar for the foundation beams • Creation of ventilation holes (for correct functioning the creation of a...

Top 4S Accessories Telestop Telestop is a modular system consisting of a stopper and a telescopic extension made polypropylene that closes the formwork and allows the simultaneous laying of of the slab and foundation beams thereby reducing costs. It can be used as a simple stopper or as an extension to avoid cutting the formwork, thereby reducing the laying time. Compared to similar products which are commercially available, it saves concrete, because the extension is the same height as the formwork to which it is coupled. The telestop system is available for Vespaio 4S H-13 → H-55....

Accessories TELESTOP

Accessories Fermoplast Is a polypropylene sheet that allows the closing of the formwork and enables the construction of the slab and foundation beams with a single laying of concrete (this product can also be used with MAGNUM). Quick and easy to lay, it can be cut with a normal cutter to fit it to the passage of tubes and systems. Compared with ordinary procedures, it can reduce the foundation construction time by up to 80%. compatible formworks

etv at work TOP 4S has been tested at the University of Trieste. Various tests have been carried out including the puching resistance test, to ensure the capacity of the formwork and therefore the safety on site. The Decree of the Ministry of Public Works of January 9, 1996, 7.2.4 - Resistance to punching says that: “In the absence of a continuous lower formwork during the phase of reinforcement and casting, blocks of any type must withstand a concentrated load, applied at the centre of the upper band of at least 1.5 kN (150 kg)." Therefore a formwork must withstand a punching load of 150...
