Description

Fireproof heat-resistant smoke shutter structure

The present invention relates to a fire-resistant heat-blocking smoke-curtain roller blind structure, in particular to a smoke-proof rubber strip in a door rail that tightly clamps a smoke-proof roller blind to effectively curb the spread of smoke, and the door rail can be actively removed. Solution, in order to facilitate the maintenance of smoke-proof rubber strips and other new fire-resistant heat-blocking smoke-proof roller blind structure.

According to the high-rise buildings in the metropolitan area, hot air, smoke and fire will spread along the corridors in the high-rise areas. According to fire statistics, most of the fires were caused by inhalation of excessive smoke, causing casualties. The rate of fire and casualties is low, so the prevention of heavy smoke turbulence in the event of a fire is an important factor in reducing fire casualties.

Most of the existing national fire protection regulations require buildings to be equipped with a smoke control system to separate the smoke when the fire occurs. The existing smoke control system mainly uses equipment such as smoke shutters. When the smoke-curtain roller blind is not in use, it is taken up in a cabinet installed in the ceiling. When the fire occurs, the smoke-curtain roller blinds are started to fall from the chassis to block the spread of smoke from the fire. However, the actual use is It is found that when the smoke roller blind is put down, the side edges of the smoke can not be attached to the door rail, and there is a gap between the smoke shutter and the door rail, especially when the front and back of the smoke shutter are often different due to the fire size. Different pressures, when the pressure is uneven before and after the windshield roll, it will cause the swaying of the smoke curtain, and the gap between the smoke curtain and the door rail will be enlarged, which will increase the spread of smoke. Even the smoke curtains are removed from the door rails, and the smoke curtains are ineffective.

The reason is that the creator has the above-mentioned shortcomings in view of the use of the existing smoke-proof roller blinds. It is the result of many years of manufacturing and design experience and knowledge in related fields, and through various ingenuity, research and creation of this creation.
