六层办公楼消防设计(2)
The six-story office building before major engineering design are: office building area of 6731.9 m², all aerial parts, a total of six layers, Housing height of 24.3m, belongs to the multi-storey building. The building is one of the business office of public buildings, the main building mainly for office, conference room, one to six for the office building. No other commercial uses in buildings, which are mostly used for office, conference room, in addition to stairways, bathrooms and other necessary facilities. The design of the main building height of 24.3m, the side skirt width 50.1m. The office building designed for two types of public buildings, fire resistance rating of 2. Set a ring around the building fire road.
The design is mainly based on the design of "architectural design code for fire protection" GB 50016-2006, "fire protection design of tall buildings" GB50045-95 (2005 edition), "automatic fire alarm system design specifications" GB50116-98, "sprinkler system design specifications "GB50084-2001 (2005 edition)," Architectural extinguisher configuration design specifications "GB50140-2005," office building design "JGJ67-2006.
The design of the building by fire hazards analysis, to make a general plan office building fire district fire district building pision, smoke partitions, fire road, etc., according to the structure and purpose as well as the corresponding specifications of the building, the building per layer is pided into a fire district, and the smoke each pided into two partitions.
Design of Fire Hydrant system includes an outdoor fire hydrant and hydrant system. Determine the number of outdoor fire hydrant and water for fire hydrant system design are made of fire hydrant 65mm diameter, 19mm gun nozzle diameter 65mm rubber lined hose length of 20m. And its full of water, fire hydrant protection radius, fire hydrant spacing.
Automatic sprinkler systems use wet automatic sprinkler system. The design uses a rectangular nozzle arrangement, the first protected area in accordance with calculations performed sprinklers, after the actual area of each room will be the number of calculations and nozzle design for each room. Then determine its location sprinklers in each room according to its length and width and the number of nozzles.
Automatic fire alarm system design is the building fire protection is an important aspect, for early fire detection and fighting extremely important. It relates to an automatic fire alarm system type selection, determine the method of fire detection, fire detectors, and several other aspects of the selection. Automatic fire alarm system according to the characteristics of commercial building construction, all the layers of the reasons for higher selection of smoke detectors, and that the distance between each of the probe according to the mounting pitch limit graph search map to determine the layout principles. Design choice smoke detectors, each layer is pided into two detection unit, the detector protection area A = 80m2, protection radius R = 6.7m. Number detector arrangement, the standard layer 18, the top eight.
And the office building to make fire extinguishing systems, automatic sprinkler system design, smoke control design and automatic fire alarm system design, then we look for a more conducive seek effective fire prevention measures and design more relatively reasonable fire protection system . Through this approach the fire from spreading to grasp design, will help us more effectively make a series of fire safety measures. Fire-depth study of the system we are only building a fire hazard, so as to take preventive measures, but also according to the future use of the security risks that may arise to design more scientific, more in line with the requirements and reasonable to a greater extent mitigate such building fire to the whole society and the environment with a great loss.
