Landscape of international settlements 57 - b floor building fire protection design
Design Notes： Design objects for the Regency International Settlements 57-b building, a project for the Anhui Properties Limited development of integrated real estate projects. 5 floors, some of which 1 to 3 layers of business, as part of a five-layer business. Height 21.60m, construction area 3831.01m². Design life of 50 years.
The main contents of this design include:  multi-building fire safety status analysis and abroad; the design focus;  the total commercial floor flat fire protection design; commercial building smoke control design; Business building safe evacuation design;  office extinguisher configuration design; commercial building fire hydrant water supply system design;Commercial building sprinkler systems; automatic commercial building fire alarm system.
This design object is a class of public buildings, fire resistance rating of 2. Design objects from the surrounding buildings and 9m, distance 6m, set fire road building around the ring between the multi-storey building within the project.
Building plan according to the structure and use of fire-resistant design and construction of the corresponding norms, the building on each floor is pided into a fire district, and the smoke is pided into three partitions each.
Safe evacuation route for the room before the room hallway stairwell. Each fire district is located in two evacuation ports, aisle width of 1.5m, two emergency exit distances greater than 5m, safe evacuation distance of 3.0m. The design provided three stairwell, a fire lift each layer.
Hazard level design objects for serious risk level, fire main types of Class A fires. Design configuration ammonium phosphate dry powder portable fire extinguishers (MF / ABC5), each carried a minimum configuration extinguishing level 3A, maximum protection distance of 15m. Determining a first set point 9 extinguisher layer 9.The second layer have 6 . The third layer 6, The fourth set point 3 extinguisher layer 3.The fifth set point 3 extinguisher layer 3.
Design calculations Fire Hydrant system includes outdoor and indoor fire hydrant system two parts. Outdoor fire hydrant water for the 20L/s, set two outdoor low-voltage ground Hydrant. Fire hydrant water for the 40L / s, hydrant protection radius 28m, layout spacing 19m, buildings were set five risers. Total head loss 0.12932MPa, the elevation difference between the most negative point of fire hydrant and fire pond lowest water level is 1.0335MPa, the most unfavorable point hydrant working pressure 0.20309MPa, the required fire pump head is 150m, traffic 45.22L / s, Selection XBD5.0 / 75-200 × 8 model fire pump, one Taiwan, one with a prepared, fire pump adapter 4. Designed to set up a fire-fighting, the effective volume of 435m3, set the effective volume of fire water tank 28m3, and no booster facilities.
Automatic sprinkler systems use wet automatic sprinkler system. In accordance with the specifications, determine its belonging to the dangerous level of Ⅰ grade risk rating. Use square nozzle arrangement designed to determine the position and shape after the most unfavorable point action area is calculated at a point within the area of the most unfavorable effect of several nozzles 14, active area 161.84m2, the most unfavorable point nozzle of the flow 69.36L / (min • m2). Pipeline total loss 0.51708MPa, the elevation difference between the most negative point of the nozzle and the lowest level of fire water 1.0545MPa, the most unfavorable point nozzle working pressure 0.08MPa, spray pump head is required to 165m, traffic 29.76L/s, Selection XBD18/40-150 × 9 type fire sprinkler pump, one Taiwan, one with a prepared, fire pump adapter three. Designed to set up a fire-fighting, the effective volume of 108m3, set the effective volume of fire water tank 18m3. 房地产建筑商业楼总平面防火设计(2):http://www.751com.cn/gongcheng/lunwen_27845.html
