The main element of this system is a barrel vault. This type of roofing forms a square structural framework of 7×7 metres. The support structure is protected on round columns with a diameter of 60 centimetres, complete with capitals to support the beams with arched intrados and flat extrados that support the vault. An effective on-ground infill wall organically completes the system, which, at the customer’s discretion, can be supplemented with a slab floor and prefabricated reinforced concrete barrel racks.
