Smoke-control And Analyse Of Big Space Buildings

This article introduced the big spatial construction classification, the fire survey and the fire fighting sprays the technological development. Has discussed the question which in the big spatial construction haze control design exists. The full text divides into five chapters, the first chapter of outline introduced the big spatial construction definition, the classified haze control research present situation; Second chapter introduces the big spatial construction fire protection technological development; Third chapter introduced Chongqing some can unfold the central performance design project the survey the analysis tool which uses with this research; Fourth chapter discussed three exhibition halls and the hall nature has discharged fume with the haze packing; Fifth chapter conclusion and suggestion.This article unifies Chongqing some to be able to unfold the central performance design project the project example, uses FDS and the PHOENICS software has analyzed with emphasis when the performance design big spatial construction haze control question, discussed the construction to surpass 12m highly the haze control mode.The analysis can unfold the central three exhibition hall smoke vent area 3% and 5% time nature discharges fume the situation for the ground, has proven in the Chongqing such summer climate burning hot condition, the natural smoke vent area takes the ground suitably 3%. Analyzed the hall haze to fill, thought but in the combustible substance few situations, might not adopt any discharges fume the measure only the way which filled naturally using the haze then to satisfy the safe scattered goal. The research indicated that,Surpasses 12m highly the big spatial construction, uses the haze packing and the nature discharges fume is the feasible haze control method, also the natural smoke vent area also may break through the standard stipulates"is not smaller than the area 5%"the stipulation. This meeting unfolds central the haze control plan to accept by the local fire prevention department.This article research indicated that,The performance design thought and the idea enter our country gradually, and receives day by day in our country construction fire prevention design takes. This article studied for the big spatial construction haze control put forward the beneficial proposal.
