The fire system design of Haley ground building
General description of the design: The design of the building  is Haley underground building fire design.The project is located in Pudong New Area, the base range east by West Camp Road, West linpu Jing Building, north Yaohua Road.The total construction area of approximately 24,481.97 square meters,Main function is office and ancillary commercial buildings,Story underground garage (and civil air defense) construction area of 3641.0 square meters including civil air defense construction area of 1833.2 square meters.Area of 1686 square meters use civil air defense, personnel concealed area of 1200 square meters, masking 1200 personnel.
   Total height of 73.4 m main building, one class of high-rise, fire resistance rating of one class, underground garage (and civil air defense) fire resistance rating of one.
Graduation design of this task are: complete Puheli building calculations and early spread of fire control system design of underground building, including building fire protection design of general layout, architectural design of smoke control, safe evacuation design, room design, inside and outside the fire hydrant, design of automatic sprinkler system, fire extinguisher configuration design and related calculations and notes.
   First determine the level of the building. the one class of high-rise buildings. According to "High regulation"3.0.4 1 class of high-rise buildings should be one class fire resistance rating,Type II high-rise building fire resistance rating should not fall below two.Skirt building of the fire resistance rating should not fall below two.the basement of High-rise building fire resistance rating should be 1. So i determine of the fire resistance rating of 1 class building.Determine the fire resistance rating, you can follow-up design.
   When the building caught fire and fire inside the building in the thermal convection and thermal radiation and spread and. Outside of the building due to severe thermal radiation effect on the surrounding buildings pose a threat.So The building should maintain a certain fire distance.Then calculation and look-up table and determine the building fire spacing 13m.This building large area building length of more than 150m. At the appropriate place to set into the backyard through the high-rise building fire road.Set fire road can quickly cross the buildings,Achieve rapid extinguishing effect.According to high regulation and norms,Through the buildings fire road are its clear height and clear width of not less than 4m;between the Gate Boules clear width of not less than 3.5m.
   Through the look-up table i know the basement of fire district is not greater than 500m2.  This can be a double self-doubling. Each of fire district is set to 1000m2. So underground layer set up three fire district,underground floors Set up 4 fire district.Because the smoke partition can not cross fire district.so the underground construction the smoke partition is not greater than 400m2,So there are nine  smoke partition in the underground layer,There are 12 underground floors in the second underground  layer. Setting fire district can effectively prevent the spread of fire.  
Feasibility of underground buildings generally through natural smoke is unlikely, because underground ventilation difficult, the basic method of mechanical ventilation. So this design to choose smoke. Smoke sets the closed smoke vents, while the use of remote-controlled smoke fire dampers. After evaluation, reach maximum air volume is 48000m3/h. 大厦地下建筑消防系统设计+CAD图纸(2):http://www.751com.cn/gongcheng/lunwen_8978.html
