Abstract (en)
[origin: EP0548486A1] In this fire-proof shaft door, improved heat insulation towards the shaft side is achieved in the event of a fire on the floor side, as a result of which the elevator shaft in case of fire is retained as an escape route for the fire brigade. A door box (24) is arranged on the floor side on a frame (23) carried by a door suspension (14), made of profiled sheet and guided by a guide tongue (22). The door box (24) is filled with heat-insulating zones and heat-insulating mats. Horizontal ribs (28) provided with ventilation holes are arranged on the shaft side on the frame (23). On the shaft side, the ribs (28) carry heat-insulating boards (29) covering the front of the door. The first hollow space (30) formed by the heat-insulating boards (29) at a distance from the frame (23) acts as a natural chimney in which fresh air designated by A circulates. <IMAGE>
