【摘要】：高层建筑火灾发生的特点决定了在建筑物内部必须设计消防给水设施并且积极地采取自救,该方法因为在火灾扑灭初期形成的较高成功率而被广泛应用。在高层建筑消防灭火系统中消防给水系统是主要组成内容,也是一项不可或缺的建筑安装项目。本文主要的研究内容如下:(1)本文分析了高层建筑消防给水系统,包括:高层建筑消防给水的形式、高层建筑消防给水系统超压与泄压问题、高层建筑消防给水系统可靠性。此外还提出了高层建筑消防给水系统存在问题与解决对策。(2)本文对广州广晟国际大厦消防给水系统进行了设计,分析了广州广晟国际大厦消防给水系统类型:消防给水系统、气体灭火装置。研究了广州广晟国际大厦消防给水系统技术:确定建筑类型以及火灾危险级别、火灾在同一时间内的次数、计算广州广晟国际大厦消防给水系统用水量的原则、延续火灾时间、消防用水量标准。明确了消防给水系统分类与分区。设计了广州广晟国际大厦消火栓给水系统:消火栓给水系统组成、消火栓布置给水管网、布置消火栓、消火栓给水系统安全设置、计算消火栓给水系统的水力。最后研究分析了自动喷水灭火系统设计。(3)本文中广州广晟国际大厦主要的供水设备是利用供水泵为高层建筑直接加压供水,可是假如供水泵出现问题或者停电就会终止供水。随着超高层建筑的运用一种重力式供水消防系统的新型供水消防系统正在逐步发展。本文简单介绍了广州广晟国际大厦重力供水消防系统,阐述了广州广晟国际大厦重力供水消防系统的基本原理,并且分析了在广州广晟国际大厦中重力供水消防系统的应用,总结了其所体现出的优势。
[Abstract]:The characteristics of fire in high-rise buildings decide that it is necessary to design fire water supply facilities and take active self-rescue in the building. This method has been widely used because of the high success rate formed in the early stage of fire extinguishing. In the fire extinguishing system of high-rise building, the fire water supply system is the main content and an indispensable building installation project. The main contents of this paper are as follows: (1) this paper analyzes the fire water supply system of high-rise building, including: the form of fire water supply in high-rise building, the overpressure and pressure release problem of fire water supply system in high-rise building, Reliability of fire water supply system for high-rise buildings. In addition, the problems and solutions of fire water supply system in high-rise building are put forward. (2) the fire water supply system of Guangzhou Guang Sheng International Building is designed in this paper. The types of fire water supply system of Guangzhou Guang Sheng International Building are analyzed: fire water supply system and gas extinguishing device. This paper studies the fire water supply system technology of Guangzhou Guang Sheng International Building, including the determination of building type and fire hazard grade, the times of fire at the same time, the principle of calculating the water consumption of the fire water supply system of Guangzhou Guangsheng International Building, and the duration of the fire. Fire water consumption standard. The classification and partition of fire water supply system are defined. The water supply system of fire hydrant in Guangzhou Guang Sheng International Building is designed. The water supply system of hydrant is composed of water supply system, water supply pipe network is arranged, fire hydrant is arranged, water supply system of hydrant is safely set up, and the hydraulic power of water supply system of fire hydrant is calculated. Finally, the design of automatic sprinkler fire extinguishing system is analyzed. (3) the main water supply equipment of Guangzhou Guang Sheng International Building is to use water supply pump to supply water directly for high-rise building. However, if water pump problems or power failure will terminate the water supply. With the application of super-high-rise buildings, a new type of water-supply and fire-fighting system with gravity water supply and fire control system is developing step by step. This paper briefly introduces the gravity water supply and fire fighting system of Guangzhou Guang Sheng International Building, expounds the basic principle of the gravity water supply fire control system of Guangzhou Guangsheng International Building, and analyzes the application of gravity water supply fire control system in Guangzhou Guang Sheng International Building. The advantages are summarized.
