Fire protection system design and management of a commercial b uilding
Abstract: The design objects 24m Siamese large commercial buildings, 24m height of the threshold between the multi-storey and high-rise buildings, the needs of the different parts in accordance with the actual situation, the GB 50016-2006 "building fire protection design specification GB50045-1995 The combination of high-rise buildings for fire protection design specifications, outdoor facilities such as places of fire climbing, climbing surface, fire road, fire spacing according to the "high regulation", in-room facilities such as fire and smoke partitions, fire water supply system, fire fighting system according to "build regulations. "
This works for public buildings, engineering grade two, the establishment of multi-layer vertical fire district building on the ground fire resistance rating of two underground construction fire resistance rating of a fire resistance rating of two, near the high-rise office in accordance with the norms, # 1 Louju the spacing of fire between there are 7,5 m> 6m, comply with the requirements. Along two streets in the construction peripheral annular fire road, three commercial buildings along the street a total length of 297.18m> 220m, the fire climbing area set in the # 1 entrance to the landlord and the east street, climbing area shall not be set green, overhead cable affect the climb things.As each floor is divided fire district, due to the largest fire district from 3000 to 5860m2 to 2500m2, but each floor is equipped with automatic sprinkler system and automatic alarm system, the fire district area can be expanded 1 times 5000m2 underground parking garage according to different functions, parking spaces and equipment room separate division of the fire district. Smoke partitions largest area of 500m2 over 500m2 set the smoke screen flue gas separator, atrium setting up of an independent smoke partitions. Automatic fire alarm system, underground parking garage flammable and explosive places JDXT-W-1 explosion-proof point type heat detectors HTSB-B21 explosion-proof manual fire alarm button and explosion-proof fire alarm; ground buildings and equipment engine room JTY-GM-GST9611 point type photoelectric smoke detectors, above and below ground evacuation routes should be set at the YB-2608 Fire broadcast, J-SJP-M-2 fire alarm button, Yae-fire alarm. The fire control room of the first floor has a fire alarm controller to monitor the situation of each layer, a fire in the control room telephone switchboard, alarm buttons and fire the important equipment room equipped with a telephone jack in each stairwell telephone extension. Hydrant water consumption 30L / s spacing of not less than 40m, placed three fire hydrant water consumption 20L / s ,1-2 layer protection radius of 24.69m, 3-layer protection radius 22.96M 5-layer protection radius 22.45m . Automatic sprinkler system underground garage deluge system, the use of open sprinkler water supply, building on the ground wet system, the use of closed nozzle water supply. Each water supply pipeline alone by the fire pump booster fire pump fire water from the side the water supply of the indoor fire water. 6-layer roof can be set to 20 tons of fire water tank, the fire hydrant water consumption 20L / s, fire water tank water storage 20m3, exhaust system, relying on the external walls of a closed stairwell open hopper windows with front room the stairwell establishment of the exhaust outlet, the maximum amount of smoke 60000m3 / h, due to the large amount of smoke on the roof to set up HTF (A) fire temperature exhaust axial fan. Each floor safe evacuation of persons is calculated about 2000, the evacuation of the partition between the walkway with shops shops operating room fire resistance 3h body does not burn, cut masonry to the floor at the end. Any of the shops to the evacuation exits straight line distance should not be greater than 15 meters, when the shops located between two security entrances, shops exports to the nearest safe exit maximum distance of 40 meters, when the shop is located on both sides of the bag-shaped walkway or the best end, shops evacuation exits to the recent security export a maximum distance of 22 meters. Set the place on fire extinguishers, commercial operating room to set a dangerous level, equipment room is set to light dangerous level. Power distribution room, freezer room dry powder MF/ABC1 extinguisher; parking the MP9, MP/AR9 foam fire extinguisher; pump room, chiller plant, power distribution control to use MF/ABC1 dry powder fire extinguishers; the distribution room MF/ABC1 dry powder fire extinguishers ; the bike library MS/Q3 water type fire extinguisher; the shops MS/T9 water type fire extinguisher. For the day-to-day security management between floors is very important, mall equipped with automatic fire-fighting facilities, regular inspection testing, maintenance system, and enhance fire control operator training and duty check mall customer traffic, there is no lack of customers smoking , free throw cigarette butts tend to cause a fire the mall should prepare the necessary time and part-time fire safety management personnel specifically do a good job the mall fire safety. Daily came from flammable liquids, to put in a closed container, as used with the open, unused returned to private warehouse shall be stored on-site.
