Three elements of designing, installing and maintaining fire doors

In recent years, the quality of fire doors has shrunk. The design and composition materials of fire doors have been substandard. Regarding the current situation, Tongxiao Door Industry will give a brief introduction to the users. In terms of design Things that should be paid attention to during installation and use
1. Reasonable design and proper selection. Designers should design targeted fire doors based on the nature and type of different buildings. When designing, they should strictly follow the requirements of fire protection technical specifications and set up fire doors reasonably. Do not lower the grade of fire doors at will.
When designing fire doors in stairwells and front rooms with positive pressure air supply systems, it should be considered that the opening area of a single leaf of the fire door matches the positive pressure air supply volume. If the opening area of the fire door is too large, when a fire occurs, the fire door may not open smoothly due to the wind pressure when the positive pressure air supply system in the stairwell is operating, which is not conducive to the rapid evacuation of personnel.
In parts of the building where there is a large daily flow of people and fire doors are frequently used, priority should be given to the design of normally open fire doors. Since normally open fire doors rely on electromagnetic release valves or magnetic door closers and automatic control systems to achieve self-closing functions, they can quickly close themselves when a fire occurs, preventing the spread of fire and the spread of smoke. This design not only facilitates the evacuation of personnel in the event of a fire, but also avoids damage caused by frequent use of fire doors.
When designing fire doors for enclosed stairwells and front rooms of stairwells that do not use positive pressure air supply systems to prevent smoke, it should be considered that the distance between the fire doors and the ceiling should be at least as small as possible, so that in the event of a fire accident, personnel can be effectively prevented from Smoke entering the stairwell during evacuation can ensure the smoke prevention effect of the stairwell.
2. Manage it properly and maintain it on time. As an important fire-fighting facility and a commonly used fire-proof partition, fire doors are widely used in buildings. Damage caused by improper maintenance and improper use often occurs, so it must be strengthened. management and maintenance.
Put an end to the one-sided pursuit of decorative effect by the user unit, cancel the fireproof door frame and only install a door cover made of ordinary wood, replace the original frame of the door leaf with other materials, and add a decorative surface layer to a large area, thus destroying the fireproof coating. Layer, no fire protection effect
Normally open fire doors should be tested regularly to check whether their self-closing control system, door closer sequencer, release switch, etc. are easy to use, and whether they can reliably open in the event of a fire. to the self-closing function, and at the same time, resolutely prevent random stacking of items next to normally open fire doors.
It is forbidden to prevent the normally closed fire doors installed in the front room of the smoke-proof stairwell or the shared front room on the evacuation corridor from being artificially opened during use and become a normally open fire door. Once a fire occurs, such a normally closed fire door will Opening a fire door will not prevent smoke and fire
Check the integrity of the fire door frequently, check whether the door closer sequencer is easy to use, whether the fire door can close itself in sequence, and whether the screws on the hinges are If it is loose and damaged, repairs should be organized immediately
Three installation specifications and quality control When installing fire doors, qualified products must be selected, the grade of the fire door must not be reduced and installation must be carried out in strict accordance with the specifications.
Resolutely put an end to cutting corners, and it is best to check it yourself during installation.
You should not make your own door frames, but purchase regular fireproof door leaves for installation
When installing fireproof doors, you should pay attention to whether they have good airtightness
When installing double doors, ensure that the door leaves fit tightly
br/> When installing the door frame and door leaf, the door should be opened in the evacuation direction according to the opening direction of the door
The door frame should not be too far away from the surrounding walls. If necessary, it should be filled with cement mortar or rock wool for sealing
Avoid door frames If the distance from the ground is too large, if a threshold is formed, it will not be conducive to evacuation
