某大厦地下建筑通风防排烟方案设计 摘要：建筑发生火灾，烟雾是阻碍人们逃生和进行灭火行动、导致人员死亡的主要原因之一。本次设计以地下建筑为素材，结合土建资料，对地下综合体的通风与防排烟方案进行了设计。文章首先论述了建筑防排烟的重要性，阐述了国内外地下建筑防排烟的发展状况，并重点对一下方面进行设计计算： 建筑的通风；建筑的机械排烟方案设计计算；建筑的防烟系统设置，机械加压送风的设计计算；排烟口的设计；排烟风机的计算与选型；排烟管道的布置等。 关键词：地下建筑 通风 机械排烟 机械加压送风防烟 排烟口 排烟风机 排烟风道 The Scheme Design of Ventilation, Smoke Prevention and Smoke Discharge of a Buildings Underground Construction Abstract: When fires happen in a building, smoke is main disadvantage reason for people to escape from the fire-ground, for firefighters to put out the fire and is also the main causes of death. The design, combined with the construction of underground engineering, give the ventilation, smoke prevention and smoke discharge scheme of the building. This article first discusses the importance of smoke prevention and discharge, then expounds history of the underground architectural smoke at home and abroad. The most important aspects of design calculation as follow: Building ventilation, mechanical smoke calculation and design of architecture, The system of smoke prevention design of architecture, design and calculation of the mechanical pressure air, The design of Exhaust port, Exhaust fan calculation and selection, Exhaust pipe arrangement, etc. Keywords: Underground building Ventilation Mechanical smoke Mechanical pressure to prevent smoke Air exhaust Smoke exhaust fan Exhaust pipe 目录 1 绪论 ………………………………………………………………………………1 1.1 地下建筑防排烟的意义 ……………………………………………………1 1.2目前地下建筑防排烟的通用方法及其优缺点 ……………………………6 1.2.1地下建筑的防烟措施 ……………………………………………………6 1.2.2地下建筑的排烟措施 ……………………………………………………6 1.3地下建筑防排烟的研究现状及发展趋势 …………………………………7 2 工程概况及设计范围 ……………………………………………………………8 2.1 工程概况 …………………………………………………………………8 2.2 存在的消防火灾隐患 ……………………………………………………8 2.3 设计范围 …………………………………………………………………8 3 设计依据及规范 ………………………………………………………………9 3.1 依据 ………………………………………………………………………9 3.2 规范…………………………………………………………………………9 3.3 防排烟设计程序……………………………………………………………9 3.4 防排烟方式的确定…………………………………………………………9 3.4.1 防烟方式 …………
