What are the requirements for the opening direction of the door of Henan Refuge Room? Fire doors play an important role in life. The opening direction of fire doors is very important. The Code for Fire Protection Design of Tall Buildings has clearly stipulated that the stairwell should be opened in the direction of evacuation, such as the stairwell should be opened in the direction of the staircase lobby, so as to facilitate the evacuation of people. major fire-resisting window In addition, the front room is generally a place of refuge and an evacuation passageway. In case of a fire, positive pressure air supply is required. If it is not installed in the above opening direction, the air pressure may open the fire door, causing fire and smoke leakage. 4.

The role of Henan fire doors in fire protection We often see on the ground of some large or local places that no one is allowed to stand under the fire facilities or shelves are placed. major fire-resisting window Then, the primary use of assembling fire doors is that if a fire occurs in a certain place, the rolling shutter door can stop the extension of the fire when it is put down. Usually, the fire doors in such large buildings have automatic central control systems. Once a fire occurs, you can automatically implement a series of behaviors, and the fire doors will automatically lower the fire. The following is the employment process of the automatic control system of the fire door. When a fire occurs, the smoke sensor installed on the roof receives the flag of the smoke and alarms to the central control system. After identification, the control system of the fire center connects the power supply of the fire door in the fire alarm location area, so that the fire shutter in the fire area will fall to the ground at the required rate. When the roller shutter passes to a position about 1.5 meters above the ground, stop the activity, so as to facilitate the evacuation and evacuation of employees on site. After the associated employees withdraw together, the fire door will continue to go down until it is closed. The descending rate of the fire door and the time of stay during the period can be adjusted according to the number of employees. fire-resisting window Manufacturer It is not only such places that are equipped with fire doors, but also in some staircases, corridors and other places. Since fire is rarely generated and some fire prevention settings are easy to use, the conditions must be inspected regularly by dedicated staff.

The classification and function of Henan fire rolling shutter door The fire rolling shutter door plays the same role as the firewall in horizontal fire separation.

Fire resisting rolling shutter door has been widely used in building engineering to make fire separation. fire-resisting window Manufacturer Fire resisting rolling shutter door is an indispensable fire prevention facility in modern high-rise buildings. In addition to the function of ordinary door, fire resisting door has special functions of fire prevention, smoke separation, suppression of fire spread, and protection of personnel evacuation. It is widely used in high-rise buildings, large shopping malls and other crowded venues. Classified fire rolling shutter doors mainly include composite steel fire rolling shutter (fire and smoke prevention), inorganic super grade fire rolling shutter (double track double shutter), steel composite water spray steam fog fire rolling shutter, steel composite lateral fire rolling shutter, steel composite horizontal fire rolling shutter, inorganic super grade folding fire rolling shutter and fire rolling shutter with various doors.
