Description
Technical field
The present invention relates to a kind of building.
Background technology
In recent years, along with the quickening of expanding economy and Development of China's Urbanization, for solving urban population growth and land resources problem day by day in short supply, urban architecture constantly develops to high level.
Though highrise building brings comfortable, attractive in appearance, grand visual experience and superior dwelling environment to us, but the safety problem that highrise building causes, especially security against fire problem is severe also, the fire of high-rise building accident caused by a variety of causes happens occasionally, and the loss caused is very large.
During high-rise building with fire disaster, its fire spread mainly contains level and spreads and vertically spread two kinds and spread mode.Level spreads and is only limiting to fire bed, and vertically spreading in traditional highrise building of fire is mainly the various vertical shafts by inside, and the exterior window of Zhongting and building etc. spreads diffusion.During fire vertically spreads, at the buoyancy that hot flue gas causes, under the effect of stack effect, the equiprobable influence factor of extraneous wind-force, the speed that the speed that fire vertically spreads will spread much larger than its level.The investigation and analysis of fire of high-rise building accident are in the past also shown to vertically spreading of fire is to cause the last main cause out of control of fire of high-rise building.In recent years along with the development of energy-saving building technology and heat insulating material, in the fire of urban skyscraper, all formed the serious event of fire that fire vertically spreads rapidly and enlarges to building interior along facade, this has increased new way for vertically spreading of fire again.
Therefore, how according to the actual conditions of architectural construction, grasp the mechanism that the facade fire occurs, develops, determine suitable fireproofing technique requirement, and then exploitation can suppress the architectural construction technology of fiery overflow and vertical fire spread, guarantee the fire savety of highrise building, become current fire safety evaluating field and be badly in need of the key issue solved.
To sum up, existing high-rise building, in structure and use, obviously still has inconvenience and defect, and urgently is further improved.The design people is research and innovation in addition actively, to founding a kind of building of new structure, makes it can effectively stop vertically spreading of fire.
