摘 要

由当代社会的快速发展所引起的现代化城市人口高度集中，高层、超高层和地下建筑量开发建设等的一系列社会现象,在让人感叹社会发展之快的同时，也不得不让人注意到由与现代公共建筑的极速发展所带来的一系列新的发展问题。这些问题具体表现在造价的不断提高 ,管理费用的快速增加,设备要求的日渐复杂,施工难度的快速增长,建设周期的加长,工作条件的越来越受到限制等方面, 随之而来的消防问题也更加难以解决 。除此之外，公共图书馆具有较大的结构耐火等级、较大的建筑火灾负荷、其所配置的消防设施较易缺乏或配置不当，火灾蔓延的速度极快、火灾的扑救难度大，而且引发其发生火灾的影响因素较多。本设计则主要从消防本质的安全角度对某公共图书馆进行消防给水的系统设计。

本工程为层高为26.5m的公共图书馆，建筑层数为地上五层。通过查阅相关消防设计规范，我们可以确定该建筑为危险级别为中危险Ⅰ级的一类高层公共建筑。此次设计的主要内容主要涉及到消火栓给水系统与自动喷水灭火系统的设计计算以及相关消防给水系统图纸的绘制。其基本步骤为在相关原理介绍，规范规定，以及了解实际工程情况的基础上，进行设计计算，并在最后绘制出符合实际的图纸。

Design of fire-extinguish system on A public library

ABSTRACT

The rapid economic and social development has caused a high concentration of modern urban population. A series of phenomena such as the development and construction of high-rise buildings, super high-rise buildings, and underground building volumes have caused people to sigh. They also have to be noticed by modern public buildings. Many uncontested new issues arising from the development, such as the continuous increase in cost, the rapid increase in management costs, the increasing complexity of equipment requirements, the rapid increase in construction difficulties, the lengthening of the construction period, and the increasingly limited working conditions, The fire safety problems that come are even more difficult to solve. In addition, public libraries have large structural fire resistance ratings, large building fire loads, and relatively easy or inadequately configured fire-fighting facilities. Fire propagation is extremely fast and fire fighting is difficult. There are many factors that cause fires. This design mainly focuses on the firefighting water supply system design of a public library from the angle of fire safety.

This project is a public library with a floor height of 26.5m. The number of buildings is five stories above the ground. By referring to the relevant fire design codes, we can determine that the building is a high-rise public building with a dangerous level of medium-risk class I. The main contents of this design mainly concern the design and calculation of fire hydrant water supply system and automatic sprinkler system and the drawing of relevant firefighting water supply system drawings. The basic steps are to carry out design calculations based on the introduction of relevant principles, specifications, and understanding of the actual project conditions. At the end, the actual drawings are drawn.
