In recent years, urban construction more and more high, high-rise building fire is also emerge in endlessly, and intensified. The update of the hardware of the fire is miss floor height increases, the speed of the high-rise building after the fire, the existing fire equipment is difficult to accurately on the fire extinguishing, causing the fire spread further relief difficulty increasing, casualties and property loss is also on the rise, high-rise building fire prevention and control has become a social problem.

And in the need of fire safety, high-rise building fire door basic installation is one of the essential things. Fire door and cheetos, Beijing branch into the dragon control system co., LTD., the scientific research experts specially in the simple introduction for everyone.

There are many types of fire door have coloured glaze fire doors, stainless steel fire door, ordinary steel fire door and fire door monitors and other related products, but is basically the same installation method according to the scene of the case may be, there are some common installation parameters must be careful.

A, the installation of fire door should be in accordance with the types of fire door, take appropriate installation method.

Second, the fire door frame can be fixed by bolts and wall body, can also be in masonry wall is embedded at the mouth of the cave iron, installed with welded frame fitting.

Three, door frames and wall body no matter adopt what kind of connection mode, each side all should not be less than three anchor point, and should be strong.

Four, installing a fire door, should first find straight, condole is, measured right after the temporary fixed, and correcting, adjust, and correct the rear can connect anchorage.

After five, required sliding door installation of push-pull flexible; Swing doors open, convenient and close close firmly.

Six, fire doors must be installed on the door closers, to open the door to the installation sequence.

The shake handshandle of seven, fire door, fire locks and other hardware accessories, must be complete;

Eight, requirements and the clearance between the ground plane should be not more than 5 mm.

Steel fire door price moderate, but its big, open more laborious and style is monotonous, is not beautiful, so much for the civil building of industrial architecture and general class, or construction of beautiful demand is low, the usual traffic small parts (such as computer room, garage, etc.); A wooden fire door, on the contrary, light weight, good opening and closing flexible and can be a decorative appearance, pattern is more, but the price is higher, more used in the civil building or construction of the top grade important occasions. General has grown two millimeters each fire door for the biggest hole size is about: 3.3 m, 1.1 m wide - single, double door 3.0 m. Engineering design in addition to strictly according to the specification requirements of the occasion, open area, width, level and direction set fire door outside, still should be paid attention to:

Fire doors are generally located in evacuation path (e.g., stair, front room, corridor, etc.), slightly do not pay attention to when building plane detail design could cause after the doors open shade evacuation path, reducing the effective width, in violation of the basic requirements for evacuation. In evacuation path turning point and the phenomenon is particularly prominent in high-rise residential, should be caused take seriously, to avoid them.

To the adjacent partition evacuation problems

Under certain conditions, when has the class a fire door to adjacent fire partition, each partition is allowed in the high-rise building is only set up a security exit. Should note that because of the fire door can only be one-way open, if the adjacent partition is only one exit, you should has grown two millimeters in the firewall set up two fire doors and respectively on both sides to open, to meet the needs of the each other between two partition evacuation.

The most commonly used is normally closed fire door, it has been in a closed state, the doors of personnel by manually opened, closed by a door leaf itself after; If push bolt installation hardware is more conducive to speed up the evacuation. In public channel, however, normally closed fire door at ordinary times when using influences ventilated daylighting, the shortcomings of buildings, traffic inconvenience, such as poor management, its door closers and open-close hardware is often destroyed, failure, cause potential safety hazard. A normally open fire door to solve the above problems, its door leaf is on the door at ordinary times is fixed in the open position, fire door device automatic release, recovery and normally closed fire doors the same function. Due to increased the automatic door opener and release system, sometimes with automatic alarm system linkage, the normally open fire door is bound to increase the building cost of projects. The current code for fire protection no way which open/close to the fire door is mandatory, but by the designers to comprehensively consider the standard of construction of high and low buildings, using the features of the occasion, management needs and economic factors.
