Economic development, population growth, urban construction requires speeding up the construction of high-rise buildings, design and construction technology of high-rise buildings in China are entering the international advanced level. In addition to a large number of high-rise residential building outside, increasing public high-rise hotels.  Fire safety design of high-rise hotels have many special problems must be taken seriously. This project is a downtown high-rise hotel, located in the crossroads, activities and parking in front of hotel, hotel is a high-rise building, on the ground 22 with a total construction area of 30985m², hotel standard floor 1280 m², building height 80m. The ground a layer main using function for distribution room, and air conditioning room, and fire control room, and reception hall, and Office, and beauty salons, and Mall, and and bar, total accommodate number ceiling for 180 people; ground II layer main using function for Ballroom and restaurant of rooms, total accommodate number ceiling for 380 people: ground three layer main using function for restaurant and Cafe, total accommodate number ceiling for 280 people; ground four layer main using function for gym, and billiards room, and table tennis room, and bowling room and KTV rooms, Total capacity up to 150 people; five floors above the ground to 22 floors on the main function room, the capacity limit of 200 people.      The hotel is a class of buildings, the presence of a wide range of fire hazards in fire safety. Such as intensive in-room staff and a lot of liquidity, hotel, conference hall and a large number of shopping malls in the use of electrical appliances, such that a single fire fighting equipment can not do all things ready. More fuel chamber, small room space, and each room has windows, better ventilation, once the fire spread quickly and is easy to form a large area of combustion, increased fighting difficult.      The fire in a high-rise hotel is designed for the national fire protection design specifications and relevant industry standards as the basis, combined with the hotel's fire-related design features and layout of the building carried  out. This design is improving its fire resistance, reduce fire hazards, meet building fire safety purposes, conscientiously implement the "applicable, economic, security," that is safe application of advanced technology, reasonable and economic principles.  Specific design elements include: building fire resistance rating of determining total building layout, building layout, interior decoration, safe evacuation, indoor and outdoor fire water supply systems, automatic sprinkler systems, fire extinguishers configuration, automatic smoke control systems and fire alarm systems design.      Specific design programs are as follows:      A. rating of one of the engineering and construction, refractory grade level.      B.  of the project with the surrounding buildings  to maintain proper fire spacing, meet regulatory requirements. An annular fire road around the building.      C. this project a total of three fire district and three smoke partition.      D. The total project plane equipped with six emergency exits, including emergency exits smallest width of 1.5m; the main part of the hotel has a total of three emergency exit; were designed hotel has two stairwell; evacuation width, security evacuation distance, required evacuation time are in line with regulatory requirements.      E. Part of the project site and shopping malls all parts of decoration materials combustion performance levels are in line with "interior decoration of buildings for fire protection design" requirements.      F. The fire water supply project water for municipal water supply network and fire-fighting. Outdoor fire hydrant system design using linear distribution in the pipe-line arrangement of outdoor fire hydrant. Each with a floor-type low pressure fire hydrant in the Northeast, the South side of the building, outdoor fire water to 30 L / s.      G. The project with the fire hydrant system is a low-pressure pump and tank water supply system. The hotel part of its water for the fire hydrant 33.6L / s, fire water volume of 18m3, arranged a ground water pump adapter, and set a fire hydrant on the flat roof of the roof.      H. The project fire danger rating for Class I in danger. Wet automatic sprinkler system, the system of water pipes in a ring shape, with the sides of the center uses water pipes water supply arrangement. Independent of wet alarm valve, and equipped with alarm control device. Automatic sprinkler system sprinkler strength 6L / minm2, active area of 160m2, arranged nozzle spacing 3.6m. The most unfavorable point nozzle working pressure of P0 = 0.05MPa. Hotel sprinkler system Total system flow 30.78L / s.      I. place this project as a whole Extinguisher A fire danger rating as a serious risk level, each matching a fire extinguisher set point ammonium phosphate dry powder portable fire extinguisher.      J. This project uses natural combination of smoke and smoke way. Part of a hotel room can be opened outside the window, naturally smoke, equipped with mechanical exhaust stairwell.      K. automatic fire alarm system to protect this project grade level, the use of the fire alarm system control center form. System with the fire control room, fire emergency radio, manual fire alarm buttons. Smart smoke detector, which are used in the form of point-type fire detectors arranged. 高层宾馆火灾隐患分析与消防设计:http://www.751com.cn/gongcheng/lunwen_61752.html
