To relate to the following standard: GBJ50016-2006《Code for fire protection design of buildings》， GB50116-9《Code of design for automatic fire alarm system》， GB50084-2001 《Code of design for sprinkler systems》， GB50015-2003《Code of design for architectural water drainage 》and so on.
The main body of this design is a fire system of three layer restaurant, the restaurant belongs to multi-storey buildings. The three layer restaurant standard layer of 38.1 m long, 21.3 m wide, the height of 3.3 m. Set up three layers on the ground, one under the ground, the floor area of each layer is 811.53 m3, underground area is 749.76 m2. Mainly in the construction total plane design is the determination of fire prevention span and fire lane design. The fire resistance rating for the secondary design object, according to the specification requirements, and adjacent buildings fire separation must be at least 6 m. Fire lane design USES annular fire lane, the net width of the fire lanes and headroom shall not be less than 4.0 m, roundabouts are connected with other lanes in two places, and set up 12 m x 12 m in the lanes at the end of back to the yard. Mainly in the fire zone of fire zone pision, main classification principles: at the request of the specification, the pision of economic and reasonable fire zone. One of the biggest protection partition is 2500 m2, and equipped with automatic sprinkler system, so in theory a biggest fire zone is 5000 m2, follow the principle of fire zone pision at the same time, according to the fire zone's maximum allowable surface integral, horizontal direction each layer as one fire compartment, the fire resistance of not less than 0.75 h room partition space; Vertical fireproof partition for each floor area. Outdoor fire hydrant system design is based on building fire resistance rating and size, determine an outdoor water to put out a fire is 20 l/s, calculated for outdoor fire hydrant number is 2. First of all, Indoor fire hydrant fire extinguishing system design should establish hoses to enrich the height of the water column, thus calculate the radius of each fire hydrant protection, according to draw each layer of the protection radius of hydrant, each layer of a total of three fire hydrant, mapped the indoor hydrant system diagram, determine the most unfavorable point three fire hydrant, carries on the head and flow of the hydraulic calculation to determine the fire pump. According to the calculated head and flow rate to choose fire water pumps, pump models for IR100-65 - j - 250 - a single stage single suction centrifugal pump, its head is 40 mh2o, flow rate of 25 l/s, and set up with a case. Calculating one hundred people width and design of evacuation route in the safe evacuation. Automatic sprinkler system design due to the influence of temperature factor is chosen wet automatic sprinkler system, establish the fire danger rating for dangerous light level, according to the fire danger rating to determine the role of sprinkler spray intensity, the system work area, nozzle pressure, select the square nozzle arrangement, mapped the automatic sprinkler system layout. In automatic fire alarm system, determine the restaurant belongs to a level 2 protection object, the alarm system is suitable for the area, according to the different height and function selection of room type fire extinguisher. Make sure the protection area and the protection of detector radius R, the calculated number of probes required, again through the limit curve for checking. Finally make sure all room number of detectors.
