Description

TECHNICAL FIELD

[0001] The application belongs to the field of prefabricated building external wall fireproof and thermal insulation, and particularly relates to an ultrahigh-rise building external wall fireproof system and a construction method. BACKGROUND

[0002] The external wall thermal insulation technology is an important building energy-saving measure, which aims to improve the energy efficiency and living comfort of buildings. At present, China is in a rapid development stage, and the buildings are close and dense, and most of them are high-rise buildings. On the one hand, if the fireproof performance of the thermal insulation material does not meet the requirements, once a fire occurs, the fire spreading speed is extremely fast because the thermal insulation material penetrates the building external wall surface, and various vertical shafts help to spread the fire. In high-rise buildings, there are many residents and a large population, and the building height is high, so it is difficult to evacuate the personnel. The current fire-fighting technology in China has limited high-rise rescue capacity. This will cause immeasurable huge losses to the personal safety and property of residents. On the other hand, if rock wool is used as a high-rise thermal insulation material like in foreign countries, the rock wool production technology in China cannot fully meet the external thermal insulation requirements, and the rock wool resources in China are few and the production cost is high, which cannot meet the demand of the thermal insulation industry in China.

[0003] The fireproof performance of the external wall thermal insulation structure in the prior art is low, and there is a lack of separate modular area fireproof measures. Once a fire occurs, it will spread rapidly, causing casualties and property losses.
