摘要：设计对象为交通信息楼。建筑高度为72.45m，设计使用年限为50年。本次设计的主要内容包括：火灾危险性分析；存在的问题；总平面防火设计；防排烟设计；安全疏散设计；灭火器配置；消火栓给水系统设计；自动喷水灭火系统设计；自动报警系统设计。本次设计对象为一类高层建筑，耐火等级为一级。设计对象与裙房9m的间隔满足要求。交通信息楼每层的面积都不超过1500㎡，所以将每层可划分为一个防火分区。该项目属于一类办公楼建筑，所以顶棚采用A级材料，固定家具采用B2级材料，其他采用B1级材料。根据规范得知，交通信息楼危险等级为严重危险级，火灾类型主要为A类火灾。设计配置磷酸铵盐干粉手提式灭火器（MF/ABC5），将该建筑每层作为一个计算单元，计算单元的最小需配灭火级别为11.29A，计算单元中每个设置点的灭火级别为3.9A，每具灭火器最小配置灭火级别为3A。每个计算单元中有3个配置点，每个配置点设置两支灭火器。设置方式均采用嵌入式。消火栓保护半径为28.1m，经计算，立管布置根数为4根。消防水泵扬程为85m，流量为43.2L/s，同时设置有一个消防水池，一个消防水箱。自动喷水灭火系统采用湿式自动喷水灭火系统。按照规范，确定其属于中危险级I级。设计采用正方形喷头布置。喷头保护面积为9.42㎡，喷头数为15个。该建筑每层划分为4个防烟分区，排烟方式采用机械排烟，其最大排烟量为58200m³/h。该项目采用控制中心报警系统，每层定为1个报警区域，4个探测区域，每层探测器数量为13个。61961

Traffic Information Design House Fire

Abstract：Building design objects for the traffic information. Building height of 72.45m, the design life of 50 years. The design of the main contents include: fire hazard analysis; the problems; general plane fire protection design; Design of Smoke; safe evacuation design; fire extinguishers configuration; fire hydrant water supply system design; automatic sprinkler system design; automatic alarm system design . The design of the object as a class high-rise buildings, fire-resistant grade level. Design objects and podium 9m intervals to meet the requirements. Travel information each floor area of no more than 1,500 square meters, so that each layer can be pided into a fire district. The project belongs to a class office building, the roof adopts A-grade material, the use of fixed furniture material class B2, B1 level using other materials. According to the specification that traffic information is a serious risk hazard level floor level, the main types of fire Class A fires. Design configuration ammonium phosphate dry powder portable fire extinguisher (MF / ABC5), the construction of each layer as a computing unit, a computing unit to be equipped with a minimum level of fire 11.29A, extinguishing level calculating unit in each set-point is 3.9A each fire extinguisher minimum configuration level 3A. Each cell has three configuration points, each point configuration settings two fire extinguishers. Setting mode are embedded. Fire hydrant protection radius of 28.1m, was calculated as the number of risers arranged four. Fire pump head is 85m, flow rate of 43.2L / s, at the same time provided with a fire-fighting, a fire water tank. Automatic sprinkler system wet automatic sprinkler system. In accordance with the specification, it is determined which belongs to the dangerous level I level. Designed with square nozzle arrangement. Head protection area 9.42㎡, nozzle number 15. The building is pided into four each smoke partition, mechanical smoke exhaust mode, the maximum amount of smoke 58200m³ / h. The project uses the alarm system control center, each as an alarm area, four detection areas, each detector number is 13. 交通信息楼消防设计:http://www.751com.cn/gongcheng/lunwen_67958.html
