Asso 500

Asso 500 is characterized by monolithic tubular flat intrados elements, arranged with a spacing of about 5.00 m to support concrete secondary elements inclined in such a way as to create a shed with a window frame height of about 105 cm.

The targeted selection of the tubular section, much stiffer than the open ones, ensures greater torsion resistance than roofs made completely of concrete with a high resistance to fire (up to R180′ for the entire system including vaults and metallic posts) for openings greater than 30 m.

Waterproofing is attained by using bituminous, synthetic and aluminum coverings. However, the standards in terms of walking resistance of the coverings are guaranteed, as required by the regulations, specifically when (photovoltaic and thermal) systems do exist. The anti-seismic connections to the primary beams take place by means of mechanical blocking systems.
