Structural improvement of fire shutter device

The present invention provides a structural improvement of a fire shutter device, in particular, a soft guiding tube is arranged in the two side sleeve portions of the fire shutter, and a sleeve is pressed at the top end of the soft guiding tube. The reeling direction of the reel produces a relatively curved deformation of the retracting portion, and the reeling portion can be used to guide the fire shutter to smoothly close or open.

According to the current high-rise buildings in the metropolitan area of the society, no matter whether it is at home or office, public places, etc., a large number of decorative materials will be used for the design of the indoor environment, and the indoor environment will be beautifully decorated, but a large number of trenches will be installed. The material is extremely flammable. In the event of a fire, the decorating material is prone to strong smoke, blocking the escape route, and delaying the escape and rescue time, and found in the fire statistics, caused by the fire scene. Most of the casualties were caused by inhaling too much smoke, and the proportion of those who were directly burned by fire was lower.

Therefore, in the current architectural design and planning, it is necessary to consider the safety at the time of fire to prevent smoke from smashing. Therefore, most of the interior of the building will be equipped with a smoke control system to generate smoke from the fire. Separated, and the existing smoke control system mainly uses equipment such as smoke-proof fire shutters. The advantage of the smoke-proof fire shutter device is that when it is not used, the roller blind can be retracted by the reel.

Safety and evacuation routes to reduce damage and damage caused by fire.

Moreover, in order to prevent the fire shutter from being closed, the effect of preventing the smoke from being smashed can be achieved, and the fire shutter should be kept in a smooth manner during the hoisting or lifting process, and is arranged inside the sleeve of the two sides of the fire shutter. There is a rigid guiding tube to help keep the fire curtain rolling down or rising smoothly. However, since the top of the rigid guiding tube is mostly not in contact with the reel, the fire shutter is closed or raised. In the process, the fireproof roller blind is easy to connect with the rigid guiding tube, which causes the fireproof roller blind to be stuck inside the roller box, even damage, malfunction, etc., and, due to the burning phenomenon inside the fire area, a large amount is generated. The hot air flow, so the gas pressure inside the fire area is larger than the area where the fire is not spread, so that the two sides of the fire shutter are subject to different pressures, which may cause swaying, pulling, etc. When the phenomenon is too strong, the fire shutter is more difficult to connect to the rigid guiding tube, and the fire shutter device cannot exert its effect of blocking the turbulence of the smoke, thereby threatening the personnel.
