According to the specification and calculation, the fire grade of the building is determined to be first class and the fire distance is 13m, because the total length of the street is 240m, so the fire lane that passes through the building is used.

According to the standard, the building fire zone and the smoke control partition are determined. The basement of the building is pided into one fire area, one layer, two layer, three layer, four layer and five layer are pided into 3 fire zones, 2 fire zones are pided in six layers, and a fireproof partition is pided on the roof layer. The location of smoke prevention zone is approximately the same as that of fire prevention zone.

The building's safety exit, evacuation distance and evacuation width are set up through building design specifications. By calculation, the evacuation exit width of the basement is 1.21m, the width of one layer is 13.7m, the width of two layers is 13.6m, the width of the three layer is 14.3m, the width of the four layer is 25.4m, the width of the five layer is 19.0m, the width of the six layer is 25.5m, the width of the roof layer is 3.1m. The number of safety exits should not be less than two, and the safe evacuation distance should not be less than 35m.

Determine the fire extinguisher's configuration, quantity, protection unit and model according to the specifications. The fire hazard grade of this building belongs to the light dangerous grade. After calculation, the design object uses the portable ammonium phosphate dry powder fire extinguisher, and each setting points 2 4kg portable MF/ABC4 extinguishers. The protection distance of the fire extinguisher is 25m, and the number of fire extinguishers is 8 in the basement; one or two layers and 15; three or four and five layers. 12; six layers and 7; 3 on the roof.

According to the specifications, the location of natural smoke exhaust, the amount of mechanical smoke and smoke and the choice of fans are determined. First, the part of the natural rehearsal is calculated, and the effective area of each room is calculated, and it is verified that the area of the smoke window is not less than 2% of the room.

After the calculation of the mechanical smoke exhaust part, the maximum smoke exhaust volume of the building is 155280m3/h, so finally choose Y200L2-2 type fan.

The fire alarm system is designed according to the specifications. According to the regulations, this building belongs to the first level protection object. The alarm area is roughly the same as the fire zone. The basement is a warning area; the first floor to five layers is 3 alarm areas; the six layer is 2 alarm areas; the roof layer is 1 alarm areas; each room is used as the detection area. The design object uses smoke detector. After calculation, the number of detector in the basement is 34; the number of one or two layers of detectors is 59; the number of three or four and five layers is 49; the number of the six layer detectors is 21; the number of the roof detector is 3.

The design of indoor and outdoor hydrant is carried out according to the standard. Outdoor fire hydrant is a water supply facility which is placed outside the building for fire water pipe network. It is mainly for fire extinguishing from municipal water supply network or outdoor fire water supply network. It can also directly connect water belt and water gun water to extinguish fire. It is one of the important fire fighting facilities to save fire. According to the regulations, the outdoor fire hydrant flow rate is 40L/S, and the quantity is not less than 3.

Indoor fire hydrant is the indoor pipe network to the fire field water supply, with the valve interface, for factories, warehouses, high-rise buildings, public buildings and ships and other indoor fixed fire facilities, usually installed in the fire hydrant box, with fire hose and water guns and other equipment. According to the specifications, the fire hydrant flow rate is 15L/S, and 3 water guns can be used at the same time. The minimum flow rate of each vertical pipe is 10L/S. The hydraulic calculation of the pipeline is completed, and the effective volume of the fire water tank and the fire pool is determined to be 21.132m3278.856m3. Finalize the lift and flow of the fire pump and select the XBD40-60-HY type pump.
