Abstract (en)
Door structure and method for eliminating excess pressure caused by a fire and the concomitant force that holds an inner door shut in connection with a double-leaf door structure (100) in a fire situation.In the method according to the invention, excess pressure is equalized between the room interior (H1) and the intermediate space (V) between the inner door (T1) and the outer door by equipping the inner door (T1) with a pressure-equalizing channel (O1), by means of which the air space in the room interior (H1) and the air space in the intermediate space (V) are joined, whereupon the opening of the inner door (T1) is facilitated and the force holding the door shut resulting from the pressure difference is significantly reduced.
