The fire resistance of the walls around the evacuation floor and the bulkheads in the evacuation floor shall not be less than 3.00h, and the bulkhead doors must be fire doors. Henan refuge bay door 2. As the equipment floor: 1) Gather various equipment and pipeline shafts into compartments. The flammable and combustible liquid or gas pipeline shall be located in the center, and the equipment pipeline area shall be separated from the fire prevention area and evacuation area. The fire prevention limit of the firewall is 3.00h or more. 2) The pipe shaft and machine room must be separated from the evacuation area, and the fire partition with a fire limit of 2.00h or more shall be used. Pipeline wells and equipment doors shall not be opened directly to the evacuation area. fire resistance steel door direct deal If you really need to enter the evacuation place, the distance from the entrance to the evacuation place must be at least 5m, and fire doors must be used in the evacuation room.

In order to protect life and property in time and effectively in case of fire, the fire door of Henan refuge room adopts double-sided fireproof board according to the fire protection design requirements of high-rise building refuge room, so as to achieve dual internal and external fire prevention treatment. The Class A 1.50h and Class B 1.00h fully meet the fire protection requirements, which can strive for greater rescue opportunities for people in case of fire, Make sure there is enough time for rescue. high quality fire resistance steel door The fire door of the refuge room is rarely noticed, but it is related to everyone's life safety. When a fire occurs, the fire protection of the refuge bay i] can play the role of fire isolation, isolating the highly toxic smoke and high temperature outside the refuge bay. Provide shelter for people in high-rise buildings and provide more opportunities for emergency rescue. For residential buildings with a building height of more than 54m, each household shall have a refuge room, and the door of the room shall be straight with Class B fireproof door, and the fire resistance integrity of the external window shall not be less than 1.00h. In terms of the current hardbound house configuration in China, a refuge room will be provided for high-rise buildings above 54 meters- The fire resistance limit of the fire door of the general refuge room is about 1h according to the fire control requirements, so that people can escape into the relatively safe environment of the refuge room within one hour of the fire. In recent years, with the growing development of high-rise buildings, skyscrapers have sprung up, and fire doors in shelters have gradually been recognized. fire resistance steel door direct deal In order to meet the requirements of high-end buildings for the fire door of refuge room and the surrounding decoration style. Fire doors in shelters are also new. Style panels are more diverse. It is no longer as rigid and dull as the old fire door.

Maintenance and cultivation of Henan fire rolling shutter All fire rolling shutters should be checked and tested once a week. The test content includes: fire rolling shutter escape function test. high quality fire resistance steel door After the fire roller shutter is in the linkage state and drops to the bottom, press any manual button on both sides of the fire roller shutter, and the fire roller shutter shall be able to rise to the limit position (or drop to the bottom again after a delay). The lifting, lowering and stopping test of the manual buttons on both sides of the fire shutter. The fire rolling shutter shall be able to operate according to the instructions, and the operation shall be stable without blocking, not to mention uneven running speed of the shutter, stacking of the shutter or derailment. Test of manual emergency device. The manual zipper is used to lift the fire shutter, and the manual quick release device is used to lower the fire shutter. The fire shutter shall be able to run smoothly. Simulate the fire signal for linkage test. It is required that the fire shutter should be able to descend according to the normal procedure, and the contents and parts displayed in the fire control room should be consistent with the actual situation. Check whether the sealing of fire shutter is intact and damaged. The inspection above Henan fire rolling shutter door shall be carefully recorded, and the problems found shall be solved in a timely manner without leaving hidden dangers. Check whether the appearance of the fire shutter is intact and whether the curtain surface is damaged. Henan fire shutter door The door leaf of Henan fire shutter door cannot move: sensor failure is the major cause of the fire shutter door leaf cannot move. When such a situation occurs, be sure to check whether the sensor signal light is normal. If it is not the fault of the sensor, it may be that the wire connector is loose, the belt falls off, the controller is burned, the foreign matter is stuck, the voltage is abnormal, and so on. Pay attention to check and eliminate them one by one. fire resistance steel door direct deal The door leaf of the fire rolling shutter jumps when opening and closing: the reason for this fault is very simple. If the track of the fire rolling shutter is jammed by foreign matters, it is necessary to check the tracks on both sides of the door leaf, remove the foreign matters, and the fault can be solved. The opening and closing speed of the fire shutter door leaf is too slow: customers often hear this situation. It may be that the speed adjustment of the national controller is too slow, or the belt is too loose, resulting in friction between the fire shutter door leaf and the guide rail. When handling, check these two parts. If the speed is too slow, adjust them faster. If the belt is too loose, tighten it in time.

Precautions for Henan fire doors There are many types of fire doors, such as glazed fire doors, stainless steel fire doors, and ordinary steel fire doors.
