 Fire protection design of the Emergency Building

This project is a hospital emergency building, the building is a civilian multi-storey public buildings, underground, on the ground floor five. Total construction area of 953.52m2, of which the ground floor area of 935.37m2, underground construction area of 938.45m2. The fire spread quickly, the fire quickly developed; personnel density, evacuation more difficult; dangerous chemicals, and more, and easy to produce a large number of toxic smoke; building internal structure is complex, the difficulty of fire fighting and other characteristics. If the fire design is not properly, there will be a lot of fire hazards.

This design based on the national building fire protection design code and related industry standards, combined with the actual situation of the project to carry out related work. Through scientific and rational design, to meet the fire safety level of the building, and to ensure the safety of personnel in the building. The concrete design content includes: building fire-resistant design, general layout of buildings, fire compartment design, personnel safety evacuation design, fire extinguishing device configuration design, design of hydrant water supply system, automatic sprinkler fire extinguishing architectural design, anti smoke exhaust system design and automatic alarm system design.

The specific design scheme is as follows: 

(1) The project is a multi-storey civil public buildings, and its fire resistance rating is determined to be the first grade.

(2)The minimum fire distance between the emergency building and the surrounding buildings is also greater than 12M, which meets the requirements of the specification. The building is surrounded by a ring of fire lanes, the width of the ring fire lane 4m, fire lane center from the building exterior design for the 7m. Set the front square of the hospital to the car's return.

(3) The level of the project fire zone pision, the underground layer, the first layer, the two three four five layer, respectively, 1 fire partition. Vertical pipe hole, staircase, and other parts of the fire vertical spread of fire, pided into vertical fire zone. 

(4) According to the specification is pided into three safety evacuation zone. The first layer of a total of 3 security exports. Design of the safety evacuation, the evacuation distance to meet the requirements of the specification. Design between the two staircases, respectively 1# No., 2#, closed building, stair width 1.8m, and open to the staircase door adopts B fire door. Stairs 2# between belt in the antechamber of the anti smoke stair, stair width 1.1m, to the door of the vestibule and staircase were the class B fire door. 

(5)The construction of each fire extinguisher set point matching 5kg with 1-2 portable ammonium phosphate dry powder MF/ABC5 fire extinguisher, each unit should be equipped with a number of fire extinguishers: 6, the first floor of 6, 6, two three four five. 

(6) The engineering design of the outdoor fire hydrant system, using dendritic outdoor fire pipe network, from the municipal fire pipe network of water supply directly way, set up the two outdoor fire hydrant, the ground type fire hydrant, fire hydrant in the types of SS100/65 type fire hydrant. Indoor fire hydrant system set a fire water tank and the water pump of the temporary high pressure system indoor fire hydrant water supply system, for improving the water supply reliability, indoor fire hydrant pipe network design for the annular building vertical hydrostatic pressure no more than 1.0MPa. The set up gun full water column length above, nozzle caliber 19mm, pressure 170KPa, flow 5.2L/s, using 65mm diameter of hemp fabric hose. Fire hydrant layout spacing is 24.5m, the fire hydrant layout as a single row, 3 rows of fire hydrant, a total of 3 layers of fire hydrant. Water 10.4L/s design of fire hydrant system. The installation of indoor fire hydrant bolt from the ground height of 1.1m, plug the mouth of the direction of the water down and set the wall of fire hydrant in the vertical. The system adopts fire pump, water supply mode, select fire hydrant pump 2 sets of 1), model: 65MS * 7-11 type centrifugal pump two with (1,. The construction of indoor fire hydrant system three pump adapter settings, each pump adapter with DN175mm galvanized steel pipe connected to indoor fire hydrant pipe line. The calculation capacity of water supply fire pool is 98.8m3.
