Fire exit integrated with fire exit

摘要

The content of this study is that one side of the shutter plate, which is set to rise and fall freely along the guide rail in a fire, is provided with an emergency exit integrated fire shutter.Such a study.The shutter plate (20) is divided into the upper section with the shutter function and the lower section formed by the emergency exit (40),In the lower part of the guide rail (30), the auxiliary rail (32) is narrowed to form a smaller width due to the inward mandible (31) of the guide rail (30),The inner lower jaw part (31) of the guide rail (30) is provided with a protective device (35) to prevent the shutter (21) from being excessively close to the ground,At the bottom of the shutter member (21), in order to insert the hanging ring (21a), a fixed replacement (23) of the bypass (23a) is arranged on the top,At the opening end of the emergency door (40), a certain width opening wing (60) which is elastically inserted can be arranged on the guide rail (30),In case of fire, it not only cuts off the inflow of external air,Effectively prevent the discharge of flame and toxic gas to the outside,That is to say, in a closed space, it provides people with fast escape routes.
