建筑外墙保温系统及防火对策的研究A

建筑外墙保温系统及防火对策的研究摘要随着我国国民经济的快速增长，能源短缺问题日益严重。节能工作已成为可持续发展的重要保证。本文介绍了我国建筑能耗的基本状况，论述了推进建筑节能的紧迫性和必要性，发展外墙保温技术及节能材料是建筑节能的主要实现方式，重点介绍了目前我国建筑外墙保温的类型及其特点，结合我国实际情况，着重论述了因建筑外墙保温系统施工管理混乱导致的火灾事故及我国目前常用的保温材料的火灾危险性，提出了贯彻落实法律法规，加强消防监督审核，提高材料耐火性能，规范施工管理，开展消防教育等方面的防范对策，从而对工程中的质量问题起到预防的作用。关键词建筑节能外墙保温防火对策1ExteriorinsulationsystemandfirepreventioncountermeasuresstudyABSTRACTAlongwithourcountrytherapidgrowthofthenationaleconomy,energyshortageproblemisgettingworse.Energyconservationworkhasbecomeanimportantguaranteeofsustainabledevelopment.ThispaperintroducesthebasicsituationofbuildingenergyconsumptioninChina,discussesthepromotingenergyefficiencyofbuildings,urgencyandthenecessityofexteriorwallthermalinsulationtechnologyandthedevelopmentofbuildingenergysavingenergymaterialismainrealization,mainlyintroducescurrentexteriorinsulationofstylesandcharacteristics,combiningtheactualsituationinourcountry,thisarticlediscussesforexteriorinsulationsystemconstructionmanagementconfusionleadstofireaccidentinChinaandnowcommonlyusedheatpreservationmaterialfirehazard,putsforwardtheimplementationoflawsandregulations,strengthensupervisionandaudit,improvematerialfire,thestandardconstructionfireproofpropertymanagement,conductfireeducationetc,thusthecountermeasuresofengineeringqualityissuesinplayapreventiverole.KeywordBuildingenergyefficiencyExternalwallthermalinsulationFirepreventionMeasures2目录1绪论.............................................................................................................................................11.1本文研究的背景...............................................................................................................11.2本文研究的意义...............................................................................................................21.3本文研究的主要内容、方法...........................................................................................31.3.1本文的研究内容.....................................................................................................31.3.2本文研究的方法.....................................................................................................32建筑节能.....................................................................................................................................42.1建筑节能的基本概念.......................................................................................................42.2我国建筑用能现状...........................................................................................................42.3建筑节能的重要性...........................................................................................................53建筑外墙保温系统的构成.........................................................................................................73.1建筑外墙保温技术的起源和现状...................................................................................73.2建筑外墙保温系统的类型及其做法...............................................................................73.2.1建筑外墙内保温...................................................................................................73.2.2建筑外墙夹芯保温...............................................................................................83.2.3建筑外墙外保温...................................................................................................93.3建筑外墙保温系统的优缺点...........................................................................................94建筑外墙保温材料...................................................................................................................114.1保温材料的种类及特点.................................................................................................114.1.1有机类保温材料.................................................................................................114.1.2无机保温材料.....................................................................................................114.1.3复合型材料.........................................................................................................114.2.建筑外墙常用的保温材料及其特点...........................................................................125外墙保温体系的火灾隐患.......................................................................................................135.1外保温材料乱象丛生，缺乏行业标准及技术规范.....................................................135.2结构设计及防火构造不合理.........................................................................................145.3建筑施工周期长，交叉作业多.....................................................................................145.4中国八成以上新建建筑使用“易燃材料”.................................................................145.5外墙保温材料给火灾扑救带来困难.............................................................................155.6现有城市消防警力不足、装备落后、一些设备技术水平低.....................................156国内、外建筑外墙保温系统防火技术现状...........................................................................176.1国外建筑外墙保温防火技术现状.................................................................................176.2国内建筑外墙保温防火技术现状.................................................................................177建筑外墙保温防火安全对策的研究...........
