Fabricated building capable of conveniently controlling fire behavior, fabricating method and extinguishing method

Abstract

The invention discloses a fabricated building capable of conveniently controlling the fire behavior, a fabricating method and an extinguishing method. The fabricated building comprises a plurality ofbuilding units which are stacked, the building units comprise frame bodies and unit bodies, telescopic lifting devices are arranged on top plates of the frame bodies, and the telescopic lifting devices comprise a plurality of stretchable beams; all the stretchable beams are arranged in the top plates, the length directions of the stretchable beams are consistent with those of the frame bodies, andthe stretchable beams can stretch from ports in random ends of the frame bodies; the lower surfaces of all the stretchable beams are provided with hoisting mechanisms in the length directions of thestretchable beams; a plurality of hoisting positions are correspondingly arranged on the upper surfaces of top plates of the unit bodies and the hoisting mechanisms; the unit bodies are placed in an accommodating cavity enclosed by the frame bodies from the ports in the ends of the frame bodies. The units where the outbreak of fire occurs can be moved quickly to the ground from high positions, theheights of the units can be quickly reduced, fire extinguishing can be conveniently conducted on the ground, casualties are reduced, and it can be avoided that the fire damages the whole building.

Description

technical field [0001] The invention relates to a prefabricated building, in particular to a prefabricated building which is convenient for fire control, an assembly method and a fire extinguishing method, and belongs to the construction field. Background technique [0002] In recent years, my country is in a period of rapid economic development, and billions of square meters of buildings are built every year. Among them, reinforced concrete is still the most common construction method, and it is widely used in multi-storey buildings, high-rise buildings and super high-rise buildings. application. [0003] When a fire breaks out in a high-rise building, it will be difficult for fire trucks to extinguish it after it exceeds the fifteenth floor. Therefore, the fire protection and fire extinguishing of floors above the fifteenth floor have become the most critical issues in the design. Under fire conditions, on the one hand, it is difficult to quickly extinguish the fire from t...

AI Technical Summary

Problems solved by technology

Under fire conditions, on the one hand, it is difficult to quickly extinguish the fire from the ground to the fire point due to the high level of the fire, and the fire floor and above floors will be affected due to the spread of the fire; on the other hand, the reinforced concrete floor at the fire location and The building column directly bears the fire load. Due to the small thickness of the floor slab and the thin steel protective layer, the reinforced concrete floor is one of the components with the largest fire area and the most serious damage in the event of a fire, and is a relatively weak link in the fire resistance of the entire structure. At the same time, because the column is the main weighing component, once the temperature rises, its strength will decrease, and the component will be easily damaged. Once the column and floor slab are damaged, the superstructure will collapse and the lower floor will be impacted, causing the entire building to be damaged, causing Greater property and personal damage
