The building area of the fire compartment of stainless steel glass fire doors should be calculated by superimposing the building areas of the upper and lower floors connected. When using fireproof partition walls, their fire resistance limit should not be less than 1.00 hours; When using fire-resistant glass walls, their fire resistance insulation and fire integrity should not be less than 1.00 hours. When using non insulated fire-resistant glass walls with a fire integrity of not less than 1.00 hours, an automatic sprinkler system should be installed for protection.
The overlap size between the stainless steel glass fireproof door leaf and the door frame should not be less than 12mm. Stainless steel glass fireproof doors are generally installed at the entrance of safety passages. There is a type of normally closed fireproof swing door, and a door closer is required to be installed on this type of stainless steel glass fireproof door for fire protection.
In addition to installing a door closer on the stainless steel glass fireproof door, if it is a double opening stainless steel glass fireproof door, a sequencer, also known as a sequencer, needs to be installed. It means that there should be a certain order of closing the two door leaves of the stainless steel glass fireproof door to prevent the stainless steel glass fireproof door from being partially uncovered.
The opening direction does not meet the requirements and has not been opened towards the evacuation direction. The fire resistance limit of stainless steel glass fire doors does not meet the requirements. According to the design requirements, Class B stainless steel glass fire doors or Class C stainless steel glass fire doors were installed instead of armored grade stainless steel glass fire doors.
Stainless steel glass fireproof door
Less or no door closers are installed. Stainless steel glass fire doors located in passages and stairwells must be equipped with door closers. Without door closers, they cannot meet the requirement of being normally closed. Install fewer hardware accessories. According to the size of the stainless steel glass fire door, larger stainless steel glass fire doors should have three hinges installed on one door, some only have two hinges, some only have one hinge, and those with four screw holes on a single page only have two screws installed, which reduces the fixing strength.
The middle seam is large, the two sides are connected, and the separation is not strict, which makes it easy to pass smoke and does not play a role in fire separation. The distance from the ground is too high, and according to regulations, the distance between the inner door and the ground should be controlled within the range of 6-8mm, while some stainless steel glass fire doors can be as high as 30-40mm. Professional and excellent articles are all within the scope of the industry.
The door gap is specified as 1.5-2.5mm, with some up to 5mm. Stainless steel glass fireproof doors, together with the frame, can meet the requirements of stability, integrity, and thermal insulation within a certain period of time. In addition to serving as a regular door, it also has special functions to prevent the spread of fire and smoke.
Correctly installing stainless steel glass fire doors can effectively control the fire within a certain range in the event of a building fire, reduce fire losses, and create favorable conditions for personnel evacuation and firefighting.
