The lift as a means of transport within the city buildings, in normal use process, bring great convenience to people's life. But when some disaster, whether the elevator can be used as the escape of disaster and rescue tools, have been discussed and studied the elevator industry. Fireman lifts as fire emergency rescue tools, in reality there are many pitfalls in use process.

1 the installation of fire elevator

According to GB 50045-50045 "code for fire protection design of tall buildings" (2005 edition), the following: (1) type of high-rise building should be set the fire lift public buildings; (2) the residential tower, (3) more than 12 and 12 layer unit residential or general existent residential; (4) height more than 32 m other 2 kinds of public buildings.

Now I can see, the above most high-rise buildings are not strictly enforce the standards, will merely artificially label passenger elevator, becoming the fire elevator.

2 fire elevator manufacturing and installation requirements

Firefighters elevator is used for transporting passengers and cargo at ordinary times can double as in an emergency situation, to become a fireman lifts. In the process of manufacture and installation, not only conforms to the relevant requirement of ordinary passenger elevator, also put forward some of the other manufacturing and installation requirements.

2.1 fire elevator requirement for buildings

Manufacturing and installation of fire elevator buildings based on the following requirements: (1) the front room to production and lift shaft designed to prevent smoke from entering, (2) architectural design limited water into the elevator shaft, (3) is different from the staircase lights, fire elevator can not escape route I (4) the fire elevator in each room layer location before the arrival.

2.2 the basic requirement of the fire elevator

According to GB 26465-26465 "fire elevator manufacturing and installation safety rules, fire elevator should be in the service of each floor of the building, capsules net entry width is not less than 800 mm, the rated capacity of not less than 800 kg. Fire elevator in case of an emergency, can adapt to the high temperature range, and in the shaft and the electrical equipment on the capsules can effectively waterproof protection. When firefighters in the process of rescue trapped inside the capsules, can save themselves from capsules, or through contact means of communication to the relevant parties to request relief, from outside the car.

Three fire detection of the lift

Because of the fire elevator with ordinary passenger and cargo elevator has not been effectively distinguish, in the process of actual inspection examination organization for some inspection process is in accordance with the ordinary passenger and cargo ladder to detect. According to the general administration of quality supervision, inspection and quarantine issued TSG T7002-2011 "elevator inspection and regular inspection rules - firefighters elevator, to detect fire elevator has special requirements, must be taken seriously.

3.1 a fireman elevator inspection rules for the special requirements of unit using data

Units used in during operation and maintenance of elevator, the elevator operation management rules and regulations shall include the power supply maintenance duties, the fire service communication system of regular maintenance and test functions, etc., use the unit should also provide power supply, before the fire room, shaft fire, room fire, pit drainage facilities conform to the requirements of the relevant testimonial material.

3.2 a fireman elevator inspection rules for the special requirements of the elevator

Firefighters elevator in the building plays a fire evacuation and rescue effect, the building environment and equipment function has some special requirements. Firefighters elevator inspection gauge has special requirements of elevator the following: (1) the basic requirement of the fire elevator; (2) before the fire chamber; (3) power supply system; (4) power conversion; (5) the fire services communication system; (6) relevant identification; (7) room fire prevention; Special and protection; (8) of the shaft (9) shaft equipment protection; (10) shaft exit, the location of the access door; (11) protection and water level of the abyss; (12) to open the door the timeout alarm; (13) the fire service control function; (14). The above details in this no longer discussion.

4 conclusion

Fire elevator as an important part of modern building fire protection, the lack of its function is bound to cause a fire case of casualties and property losses. The application of the fire elevator, not only need to use the unit to carry out the requirements of relevant laws and regulations, the control of architectural design institute of architectural design and also need to lift production unit and test detection institutions to provide and guarantee for the equipment.
