gb-50016-2014-建筑設(shè)計(jì)防火規(guī)范(2015-5-1實(shí)施)

1、建筑設(shè)計(jì)防火規(guī)范GB500162014與《建筑設(shè)計(jì)防火規(guī)范》GB500162006和《高層民用建筑設(shè)計(jì)防火規(guī)范》GB5004595（2005年版）相比，本規(guī)范主要有以下變化：1.合并了《建筑設(shè)計(jì)防火規(guī)范》和《高層民用建筑設(shè)計(jì)防火規(guī)范》，調(diào)整了兩項(xiàng)標(biāo)準(zhǔn)間不協(xié)調(diào)的要求，將住宅建筑的高、多層分類統(tǒng)一按照建筑高度劃分；2.增加了滅火救援設(shè)施和木結(jié)構(gòu)建筑兩章，完善了有關(guān)滅火救援的要求，系統(tǒng)規(guī)定了木結(jié)構(gòu)建筑的防火要求；3.補(bǔ)充了建筑保溫系統(tǒng)的防火要

2、求；4.將消防設(shè)施的設(shè)置獨(dú)立成章并完善了有關(guān)內(nèi)容；取消了消防給水系統(tǒng)、室內(nèi)外消火栓系統(tǒng)和防煙排煙系統(tǒng)設(shè)計(jì)的要求，這些系統(tǒng)的設(shè)計(jì)要求分別由相應(yīng)的國(guó)家標(biāo)準(zhǔn)作出規(guī)定；5.適當(dāng)提高了高層住宅建筑和建筑高度大于100m的高層民用建筑的防火技術(shù)要求；6.補(bǔ)充了有頂商業(yè)步行街兩側(cè)的建筑利用該步行街進(jìn)行安全疏散時(shí)的防火要求；調(diào)整、補(bǔ)充了建材、家具、燈飾商店?duì)I業(yè)廳和展覽廳的設(shè)計(jì)疏散人員密度；7.補(bǔ)充了地下倉(cāng)庫(kù)、物流建筑、大型可燃?xì)怏w儲(chǔ)罐（區(qū)）、液氨儲(chǔ)罐、

3、液化天然氣儲(chǔ)罐的防火要求，調(diào)整了液氧儲(chǔ)罐等的防火間距；8.完善了防止建筑火災(zāi)豎向或水平蔓延的相關(guān)要求?！緱l文說(shuō)明】修訂后的《建筑設(shè)計(jì)防火規(guī)范》規(guī)定了廠房、倉(cāng)庫(kù)、堆場(chǎng)、儲(chǔ)罐、民用建筑、城市交通隧道，以及建筑構(gòu)造、消防救援、消防設(shè)施等的防火設(shè)計(jì)要求，在附錄中明確了建筑高度、層數(shù)、防火間距的計(jì)算方法。主要修訂內(nèi)容為：1、在“建筑構(gòu)造”一章中補(bǔ)充了建筑保溫系統(tǒng)的防火要求。2、為便于建筑分類，將住宅建筑原按層數(shù)劃分多層和高層住宅建筑，修改為按建筑

4、高度劃分，并與原規(guī)范規(guī)定相銜接；修改、完善了住宅建筑的防火要求，主要包括：1）住宅建筑與其他使用功能的建筑合建時(shí)，高層建筑中的住宅部分與非住宅部分防火分隔處的樓板耐火極限，從1.50h修改為2.50h；2）小于等于100m的高層住宅建筑套內(nèi)宜設(shè)置火災(zāi)自動(dòng)報(bào)警系統(tǒng)，并對(duì)公共部位火災(zāi)自動(dòng)報(bào)警系統(tǒng)的設(shè)置提出了要求；3）規(guī)定建筑高度大于54m的住宅建筑應(yīng)設(shè)置可兼具使用功能的避難房間，建筑高度大于100m的住宅建筑應(yīng)設(shè)置避難層；4）明確了住宅建筑

5、疏散樓梯間的前室與消防電梯前室合用的條件；5）規(guī)定高層住宅建筑的公共部位應(yīng)設(shè)置滅火器。3、適當(dāng)提高了高層公共建筑的防火要求：1）建筑高度大于100m的建筑樓板的耐火極限，從1.50h修改為2.00h；2）建筑高度大于100m的建筑與相鄰建筑的防火間距，不能按照有關(guān)要求減少；3）完善了公共建筑避難層（間）的防火要求，高層病房樓從第二層起，每層應(yīng)設(shè)置避難間；4）規(guī)定建筑高度大于100m的建筑應(yīng)設(shè)置消防軟管卷盤或輕便消防水龍；5）建筑高度大于

6、100m的建筑中消防應(yīng)急照明和疏散指示標(biāo)志的備用電源的連續(xù)供電時(shí)間，從30min修改為90min。4、補(bǔ)充、完善了幼兒園、托兒所和老年人建筑有關(guān)防火安全疏散距離的要求；對(duì)于醫(yī)療建筑，要求按3.6廠房和倉(cāng)庫(kù)的防爆...................................................................................................................
