玻(bo)璃幕墙，是(shi)指由(you)支(zhi)承(cheng)结构(gou)(gou)(gou)体系可相对主(zhu)体结构(gou)(gou)(gou)有(you)一定位移能(neng)力、不(bu)分(fen)担(dan)主(zhu)体结构(gou)(gou)(gou)所受作用(yong)的建(jian)(jian)筑(zhu)外围护(hu)结构(gou)(gou)(gou)或装饰结构(gou)(gou)(gou)。墙体有(you)单(dan)层(ceng)(ceng)和双(shuang)层(ceng)(ceng)玻璃两种。玻璃幕墙是(shi)一种美观新颖的建(jian)(jian)筑(zhu)墙体装饰方法，是(shi)现代(dai)主(zhu)义(yi)高(gao)层(ceng)(ceng)建(jian)(jian)筑(zhu)时(shi)代(dai)的显著特征。

功能作用

现代(dai)化高层(ceng)(ceng)(ceng)建筑的玻(bo)(bo)(bo)(bo)璃(li)(li)(li)幕(mu)墙采用(yong)(yong)了由(you)镜(jing)面玻(bo)(bo)(bo)(bo)璃(li)(li)(li)与(yu)普通玻(bo)(bo)(bo)(bo)璃(li)(li)(li)组合(he)，隔(ge)层(ceng)(ceng)(ceng)充入(ru)干燥空(kong)(kong)(kong)气(qi)或惰性气(qi)体(ti)的中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)。中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)有两(liang)层(ceng)(ceng)(ceng)和三(san)层(ceng)(ceng)(ceng)之(zhi)分，两(liang)层(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)由(you)两(liang)层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)加密封框架，形成一个(ge)夹层(ceng)(ceng)(ceng)空(kong)(kong)(kong)间(jian)(jian)；三(san)层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)则是由(you)三(san)层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)构成两(liang)个(ge)夹层(ceng)(ceng)(ceng)空(kong)(kong)(kong)间(jian)(jian)。中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)具有隔(ge)音、隔(ge)热(re)(re)、防结霜、防潮(chao)、抗风压强度大等优点(dian)。据测量(liang)，当室外温(wen)度为－10℃时，单层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)窗前的温(wen)度为－2℃，而使(shi)用(yong)(yong)三(san)层(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)的室内(nei)温(wen)度为13℃。而在炎热(re)(re)夏(xia)(xia)天，双层(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)可以(yi)挡住90的太阳辐射(she)热(re)(re)。阳光依(yi)然可以(yi)透过玻(bo)(bo)(bo)(bo)璃(li)(li)(li)幕(mu)墙，但晒在身上大多不会感(gan)到(dao)炎热(re)(re)。使(shi)用(yong)(yong)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)幕(mu)墙的房间(jian)(jian)可以(yi)做到(dao)冬暖夏(xia)(xia)凉，很大地改(gai)善了生(sheng)活环境。

基本分类

框(kuang)支撑(cheng)玻(bo)璃(li)幕(mu)墙是玻(bo)璃(li)面(mian)板周边由金属(shu)框(kuang)架(jia)支撑(cheng)的玻(bo)璃(li)幕(mu)墙，主要(yao)包括：

玻(bo)璃(li)幕(mu)墙是金属(shu)框(kuang)架(jia)构件显露在(zai)外表面的玻(bo)璃(li)幕(mu)墙。它以特殊断面的铝(lv)合金型(xing)(xing)材(cai)(cai)为框(kuang)架(jia)，玻(bo)璃(li)面板(ban)全嵌入型(xing)(xing)材(cai)(cai)的凹(ao)槽内。其(qi)特点在(zai)于铝(lv)合金型(xing)(xing)材(cai)(cai)本身兼有(you)骨(gu)架(jia)结构和固(gu)定玻(bo)璃(li)的双(shuang)重作(zuo)用(yong)。

玻(bo)璃(li)幕墙(qiang)是(shi)传统的形式(shi)，应用广泛，工作性能可(ke)靠。相对于隐框玻(bo)璃(li)幕墙(qiang)，更易满足施工技术水平(ping)要(yao)求。
