Smoke or fire protection cover for forming escape corridor in transportation tunnel, has retainer with deflection device, which deflects fire protection element so that element forms roof and sections of corridor in protection arrangement

摘要

#CMT# #/CMT# The cover (10) has a retainer (14) automatically bringing a fire protection element (12) e.g. fire protection textile, from a storage arrangement into a protection arrangement. The protection element defines an escape corridor in the protection arrangement. The protection element includes segments, which overlap each other in pairs when the protection element is in the protection arrangement. The retainer includes a deflection device (22) deflecting the protection element such that the protection element forms a roof section and a side section of the corridor in the protection arrangement. #CMT# : #/CMT# An independent claim is also included for a tunnel. #CMT#USE : #/CMT# Smoke or fire protection cover for forming an escape corridor in a tunnel i.e. transportation tunnel (all claimed). #CMT#ADVANTAGE : #/CMT# The retainer includes the deflection device, which deflects the protection element such that the protection element forms the roof section and the side section of the escape corridor in the protection arrangement, thus protecting persons escaping through the escape corridor against effect e.g. large heat, from outside in a better manner, and hence reducing risk for the persons, and avoiding occurrence of damages in case of impact with the escaping persons. The cover is robust. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional view of a smoke or fire protection cover including a fire protection element in a storage arrangement. 10 : Smoke or fire protection cover 12 : Fire protection element 14 : Retainer 16 : Winding shaft 20 : Tunnel wall 22 : Deflection device.
