Guiyang elevator installation company tells you the problems existing in the fire elevator.
Fire elevator is an elevator for fire fighting and rescue use and has a certain function in the case of a building fire. Therefore, the fire elevator has high fire protection requirements, and its fire protection design is very important. According to the statistics of relevant departments, nearly five years in China, nearly 1 million 200 thousand fires have occurred in China. 12268 people have been killed and 15757 people have been injured, and the loss of direct property has reached 7 billion 560 million yuan. So, what are the problems that still exist in the fire elevator?
In the code for fire protection design of buildings, safety code for manufacture and installation of fire elevators and safety code for manufacture and installation of elevators, specific provisions for the setting and use of fire elevators in high-rise buildings are put forward. But at present, in many buildings, the setting of the elevator is very irregularities and is too random.
According to the provisions of the "standard" fire protection design of buildings, the other two types of public buildings for a class of public buildings, residential tower, apartment or corridor style residential, twelve floors above the height of over 32 meters shall be provided with fire elevator. The number is when each floor area of not more than 1500 square meters, 1 units should be set up; when more than 1500 square meters but not more than 4500 square meters, 2 units should be set up; when more than 4500 square meters, should be set to 3, and so on.
At present, the fire elevator and ordinary elevator is usually arranged in the same waiting hall, lack of access to the elevator front room, unable to prevent the fire from spreading to the elevator in case of fire, this practice is wrong.
Many buildings fail to meet the above requirements in the setting of fire elevators, which are quite different from the national standards. There is a serious threat to the safety of personnel in buildings. This is a cause for attention and remedial measures. The function of fire elevator is erroneously understood. During the elevator purchase, the "forced landing function" is mistaken for the fire function order to save cost and misunderstand the elevator fire function, or to be misled by others.
The use of functional requirements of fire elevator, fire elevator should be in the fire station on the elevator switch is arranged after the elevator immediately entered the state fire control work, the elevator at any position, what state the elevator shall immediately directly to the base station, which is the function of elevator landing". At the moment, the internal call and external call button switches of the elevator are both invalid and no longer respond. The elevator opens immediately after reaching the base station, and the original registered call signal is also automatically eliminated, and the photoelectric protection and safety touchpad of the door do not work.
At that time, the fire rescuers can quickly enter the elevator car with relevant rescue tools and immediately go to the fire floor to rescue and extinguish the fire. At this point, the elevator does not have the automatic response function. Only when responding to the selection signal in the car, and after answering the first signal, the rest of the selected signals will automatically disappear. Before the floor is selected, it can't open the door automatically, and the door must be pressed to open the door. Moreover, the sedan door will be closed again once the door is not fully opened. When the car door is fully open, the door can remain open. Only by holding the closing button can the door be closed. At this time, the elevator has been changed from automatic operation to manned operation. This is the real integrity function of fire elevator, and the function of "forced landing" is only part of the function of fire elevator, rather than all its functions, so we must not misunderstand the two.
Test of the original "elevator supervision and inspection rules" to lift fire function is not perfect the original "elevator supervision and inspection rules" in the inspection of the fire lift function requires only test the "landing function", "landing" after the firefighters entered the car after the rescue operation function is not perfect, at this time, the elevator can be external call at any time call of Ladder Fire Rescue work. This inspection does not conform to the requirements of the design specification for the elevator fire protection, and calls for the follow-up function.
