High-rise building fire protection structure

Abstract

The invention discloses a high-rise building fire protection structure comprising a fixed plate, a flue gas absorbing box and a plurality of pushing units arranged on the fixed plate. The fixed plateis connected with the flue gas absorbing box through the pushing units, and the pushing units comprise piston rods, piston chambers arranged in the flue gas absorbing box and two fire extinguishing tubes; racks and fixed tubes of a hollow structure are arranged at the upper and lower sides of the piston rods; one ends of the fixed tubes are fixed on the fixed plate, and the other ends of the fixedtubes are detachably connected with the racks; the fire extinguishing tubes are provided with spray nozzles located on the outer side of the flue gas absorbing box, and the fire extinguishing tubes are internally provided with aluminum sulfate solution tubes and sodium bicarbonate solution tubes; the aluminum sulfate solution tubes and the sodium bicarbonate solution tubes are symmetrically arranged, and movable blocks are arranged between the aluminum sulfate solution tubes and the sodium bicarbonate solution tubes; second compression springs connected to the inner walls of the fire extinguishing tubes are arranged at the upper ends of the movable blocks; and air bags are arranged on the inner walls of the piston chambers for pushing the movable blocks to move, the air bags are filled with nitrogen gas, and therefore fire spreading is prevented.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting facilities, in particular to a high-rise building fire-proof structure. Background technique [0002] According to the "Regulations on Fire Protection Design of High-rise Civil Buildings", high-rise civil buildings refer to residential buildings with ten floors or more (including residential buildings with commercial service outlets on the first floor) and public buildings with a building height of more than 24 meters. With the development of the national economy and society, the process of urbanization is getting faster and faster, and more and more people are flocking to the cities. In the cities where there are many high-rise buildings, the buildings are getting taller and taller. In the blink of an eye, in Beijing, Shanghai and other big cities In the middle of the city, tall buildings have sprung up like mushrooms after rain. High-rise buildings with cutting-edge appearance and luxurio...

Problems solved by technology

[0005] 2. Difficulty in evacuation

Ordinary elevators stop running due to power cuts and other reasons in the event of a fire. The safe evacuation of most high-rise buildings mainly relies on stairs, and once smoke enters the stairwell, it will seriously affect evacuation.

[0006] 3. It is difficult to save

For example, the fire-fighting water consumption of high-rise buildings is considered according to the current economic and technological level of our country and the general fire scale. When a large-scale fire occurs, the fire-fighting water consumption is obviously insufficient, and it is necessary to use fire trucks to supply water to high-rise buildings. If there is no fire elevator installed, the firefighters cannot reach the fire floor in time to fight the fire, and the fire fighting equipment cannot be replenished at any time, which will affect the fire fighting

[0007] 4. There are many fire hazards

Some high-rise comprehensive buildings have complex functions, many combustibles, and lax fire safety management

For example, some buildings have commercial business halls, combustible warehouses, restaurants, etc.; some office buildings are leased to many units for use, and the safety management is not uniform. Once a fire occurs, it is easy to cause a large area of ​​fire
