High-rise automatic fire prevention system

Abstract

The invention discloses an automatic fire prevention system for a high-rise building, which comprises multi-storey rooms distributed up and down, each room is divided into multiple rooms, and the two side walls of each room are load-bearing walls, and the other two side walls are front walls and partition walls , Windows are set in the middle of the front wall, doors are set in the middle and lower part of one side of the partition wall, the first wall cavity type flue is set in the partition wall, the first wall cavity type flue channels of multiple rooms are relatively connected, and the inside and outside of the partition wall are set The choke door, the second wall cavity type flue is located on both sides of the window in the front wall, the third wall cavity type flue connected to the second wall cavity type flue is set at the lower end of the front wall, and the fourth wall cavity type flue is set at the upper end of the front wall Cavity-type flue, the second-wall cavity-type flue of multiple rooms is connected correspondingly, and a choke door is set on the inside of the front wall, and the fourth-wall cavity-type flue of each room is connected with the third-wall cavity-type flue of the room above , The bottom of the fourth wall cavity type flue is provided with a choke door. The invention reduces the attack probability of the fire on the lower floor to the upper floor and surrounding rooms, and reduces casualties and property losses.

Description

technical field [0001] The invention relates to the technical field of construction and fire protection, in particular to an automatic fire protection system for high buildings. Background technique [0002] First, with the serious shortage of land and the accelerated pace of urbanization and industrialization, all kinds of houses in cities and factories are rapidly developing from low-rise bungalows to high-rise buildings. Chain-like and large-scale fires have become the biggest threat. The downstairs is caught on fire, and the upstairs suffers; secondly, with the rapid development of the tertiary industry, the lower floors have naturally become the most difficult place for them to survive and develop. The best choice, but a high-frequency fire birthplace was born in this way; third, with the rapid development of industrialization, building-like production workshops emerged overwhelmingly, and another high-frequency fire birthplace also came into being. [0003] A common c...

Problems solved by technology

[0003] A common characteristic of these fires is that if any room on a lower floor catches fire, the flames can ignite rapidly, floor by floor, and successively ignite the upper floor and the adjacent rooms on the left and right within a few minutes, and the thick smoke is even more enveloping. All of the above seriously threaten the safety of people's lives and property. In just a few minutes, the fire and thick smoke ruthlessly engulfed the people in all the rooms and stairs above. In the meantime, the fire brigade is still on its way. Objectively speaking, one is that foreign aid is always lagging behind, and it is impossible to save these unfortunate people in the most critical first time. and degree, the existing fire technology and strength can only be expected
