The office has the fire spread rapidly, the rapid development; personnel density, evacuation is difficult; many kinds of dangerous chemicals, easy to produce large amounts of toxic gas; the internal structure of the building complex, the characteristics of fire fighting difficult. If the improper design will fire hazards exist very large.
This project is to determine the fire resistance rating of two. The building is arranged around the ring fire lane, Lane - net width is 4.00m, headroom for 5.00m, 5.00m from the exterior wall of the building, the fire lane connectivity in the northeast and other buildings. Two lane is also provided with a net width and clearance height of 5.00m and a fire truck corridor. The fire in the office building of the climbing surface Book West. Each floor pision of this project is a fire zone. This project has 6 exits, Front Gate exit width is 10.8m, the rest of the exit width is 2.4m. and its internal design 2 open stairwell. The width of the staircase is 3.0m.
The combustion performance of grade parts of the decoration materials within the project according to the interior decoration materials classification sequence: A B1 ceiling, metope, ground B1, B1 partition, B2 B2 fixed furniture, curtains, curtain and other decoration materials B3, B2, and a "double". This project is on the ground floor of four buildings. The first floor is equipped with 8 fire extinguishers set, each set point configuration of 2 fire extinguishers, the need to configure 16 5kg MF/ABC5 portable fire extinguisher, which is MF/ABC5 * 16; second, third, four layers are equipped with 4 fire extinguishers set, each set point configuration of 1 fire extinguishers, the need to configure 4.5Kg portable MF/ABC5 extinguisher, MF/ABC5 * 4.
The fire danger rating of this project for the intermediate grade, the wet sprinkler system. Water supply pipeline layout system. A ring of water distribution pipe with side center type water supply arrangement, and alarm control device. Set the end water test in the most unfavorable sprinkler system device. The automatic sprinkler system water density for 6L/min, M2, 160m2. area of influence is the most disadvantageous sprinkler working pressure for nozzle P0=0.08MPa. design in the area of the flow rate is 56.6L/min, 12.25m2 protected area of each nozzle, nozzle spacing is 3.5M. system design total flow 22.56L/s.
This project adopts the natural smoke exhaust way to carry out smoke control, and directly uses the room window to carry out smoke prevention and exhaust inside the room
In the office of books the first floor set fire duty room, and the fire accident in the duty room telephone set, radio, alarm controller, fire door control, fire control, smoke control and fire control water valve. All rooms are equipped with fire detectors for elevator, each layer, stair room set up before the manual alarm button, all the stairs to the floor lamp, important room is arranged in the water fire extinguishing system, each channel is provided with a safety public accident evacuation lights, each floor to set alarm system. This project uses the control center alarm system. This project set up a smoke detector, smoke detector protection area for A=60m2, protection radius R=5.8m., each floor smoke detection installation distance, a and b values are 6m and 8m, one floor needs to install 19 smoke detectors, and the remaining floors need to install 11 smoke detectors.
