摘要
System for the ventilation and smoke-clearing of buildings with skylighting. The invention allows ventilation and smoke-clearing with skylighting by vertically lifting a large part of the structure. It consists in raising a glass roof frame 1 in order to form a space E of variable height h. The frame, consisting of a framework 7 and of a glazing 4, is equipped with screw jacks 33' fixed to the fixed part 2. The synchronisation takes place by means of a shaft 5 and bevel gears. The system is set into motion by an electric motor 6 controlled by a pulse box or if there is no current with operational priority in the event of a fire. IMAGE
