Fire protection design features of super high-rise buildings

Nowadays, there are more and more high-rise buildings in China. Today, when land resources are scarce, buildings are developing in the vertical direction. Especially the existence of super high-rise buildings, this fire protection work brings great challenges. If a fire breaks out in a super high-rise building, it is very difficult to evacuate the people in the building, and the development of fire fighting and rescue work is also limited. There is a fire fighting system in time, but the effect may not be the best, and the final loss is still relatively serious. Therefore, in order to avoid fire accidents, it is still necessary to improve the fire protection design of super high-rise buildings. So, what are the characteristics of the fire protection system of super high-rise buildings?

1. The fire water consumption is large.
2. The cause of the fire is complicated.
3. The losses caused are relatively large.
Compared with the ordinary building fire protection system, the water consumption of super high-rise buildings is much larger. Moreover, there are various causes of fire, such as short circuit, electric leakage and fire caused by human factors, all of which are possible. Once a fire breaks out in a super high-rise building, the loss will be immeasurable. This is mainly because the number of people living in super high-rise buildings is large and the floors are high, so it is difficult to evacuate people. Therefore, people’s Internet access is relatively serious. Moreover, super high-rise buildings are often high-end buildings, and the cost of various facilities and objects is high, so the loss in case of fire is great.
Although the fire protection system of high-rise buildings faces many problems, these are not insurmountable. The following methods are very effective.
First of all, improve the fire water supply system of high-rise buildings. In the fire water supply system of high-rise buildings, two aspects of water balance and water pressure of fire pipes should be considered. It is better to divide the water supply system of super high-rise buildings into more than three zones, and at the same time, there should be pressure stabilizing pressure reducing orifice plates and fire hydrant equipment, so as to achieve balanced water supply. In terms of pressurization, segmented water supply can be adopted.
Secondly, there should be automatic alarm system design. In the fire protection system of super high-rise buildings, the automatic alarm design is very meaningful. If there is an alarm device, the information can be fed back to the personnel on duty at the first time when a fire occurs, so that measures can be taken to extinguish the fire at the first time, and the loss can be reduced as much as possible.
Finally, the smoke exhaust design of the fire-fighting system of super high-rise buildings is also very important. Many casualties caused by fire are not killed by fire, but by smoke. Therefore, smoke exhaust measures must be taken.
