In modern buildings, fire shutter doors are important facilities for fire separation, and their implementation standards are crucial, which are related to the safety of life and property.
The design standards for fire shutter doors are strict and clear. In terms of materials, non-combustible or flame-retardant materials are mostly used. For example, steel requires a steel plate with a thickness of not less than 1.5mm, aluminum requires an aluminum plate with a thickness of not less than 2.0mm, and glass must use tempered glass or laminated glass to ensure basic fire resistance. In terms of fire resistance, the fire resistance limit is divided into three levels: A, B, and C according to the building conditions, which are 3 hours, 2 hours, and 1 hour respectively. Different levels are adapted to different building needs. At the same time, there are clear requirements for opening and closing speed and sealing performance. Generally, opening does not exceed 30 seconds and closing does not exceed 60 seconds, and it is necessary to ensure that smoke and flames in the partition do not leak out during a fire.
In the installation stage, there are standards for the location, method, and electrical control system of fire shutter doors. It should be installed in key parts of fire partitions, such as passages, corridors, elevator vestibules, etc., so as to quickly isolate the fire source in case of fire. There are two installation methods: ground and ceiling, and it is necessary to ensure that the connection with the surrounding is firm. The electrical control system needs to use fireproof modules and has multiple operation modes to cope with different situations. After the installation is completed, strict acceptance must be carried out, covering materials, specifications and other aspects. Only after the acceptance is qualified can it be put into use.
In terms of use and maintenance, standards must also be followed. Regular inspection and maintenance should be carried out during use to check whether the opening and closing are smooth, whether the control system and sealing performance are good, etc. It is strictly forbidden to change its structure and performance at will. When a fire occurs, the emergency button can be quickly pressed to close automatically. In addition, pulleys, chains and other components should be lubricated regularly, dust should be cleaned, and damaged parts should be replaced in time.
The implementation standards of fire shutter doors are comprehensive and detailed, and there are rules to follow in every link from design to use and maintenance. Only by strictly following these standards can the fire shutter doors play their due role in fire prevention, smoke isolation and fire resistance, and protect the safety of buildings at critical moments.
