玻璃幕墙，是(shi)指由支(zhi)承结(jie)(jie)构(gou)体(ti)系可相对(dui)主体(ti)结(jie)(jie)构(gou)有一定位(wei)移能力、不分(fen)担(dan)主体(ti)结(jie)(jie)构(gou)所受作用的建筑外(wai)围护结(jie)(jie)构(gou)或装饰(shi)结(jie)(jie)构(gou)。墙体(ti)有单层(ceng)和双(shuang)层(ceng)玻璃(li)两种。玻璃(li)幕墙是(shi)一种美观新颖的建筑墙体(ti)装饰(shi)方法(fa)，是(shi)现(xian)代主义高层(ceng)建筑时代的显著特征。

功能作用

现(xian)代(dai)化高层(ceng)(ceng)(ceng)(ceng)建筑的玻(bo)(bo)(bo)璃(li)(li)幕墙(qiang)(qiang)采用了由(you)镜面玻(bo)(bo)(bo)璃(li)(li)与普(pu)通玻(bo)(bo)(bo)璃(li)(li)组合(he)，隔(ge)(ge)层(ceng)(ceng)(ceng)(ceng)充入(ru)干(gan)燥空(kong)(kong)(kong)(kong)气(qi)或惰性(xing)气(qi)体的中空(kong)(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)。中空(kong)(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)有两(liang)层(ceng)(ceng)(ceng)(ceng)和三层(ceng)(ceng)(ceng)(ceng)之(zhi)分(fen)，两(liang)层(ceng)(ceng)(ceng)(ceng)中空(kong)(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)由(you)两(liang)层(ceng)(ceng)(ceng)(ceng)玻(bo)(bo)(bo)璃(li)(li)加密封框架(jia)，形成(cheng)一(yi)个(ge)夹层(ceng)(ceng)(ceng)(ceng)空(kong)(kong)(kong)(kong)间；三层(ceng)(ceng)(ceng)(ceng)玻(bo)(bo)(bo)璃(li)(li)则是由(you)三层(ceng)(ceng)(ceng)(ceng)玻(bo)(bo)(bo)璃(li)(li)构成(cheng)两(liang)个(ge)夹层(ceng)(ceng)(ceng)(ceng)空(kong)(kong)(kong)(kong)间。中空(kong)(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)具(ju)有隔(ge)(ge)音、隔(ge)(ge)热、防结霜、防潮、抗风压强度大等优(you)点。据测量(liang)，当室外温(wen)度为(wei)－10℃时(shi)，单层(ceng)(ceng)(ceng)(ceng)玻(bo)(bo)(bo)璃(li)(li)窗前的温(wen)度为(wei)－2℃，而(er)使用三层(ceng)(ceng)(ceng)(ceng)中空(kong)(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)的室内(nei)温(wen)度为(wei)13℃。而(er)在(zai)炎热夏天，双层(ceng)(ceng)(ceng)(ceng)中空(kong)(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)可以(yi)挡住90的太(tai)阳辐射热。阳光依然可以(yi)透过玻(bo)(bo)(bo)璃(li)(li)幕墙(qiang)(qiang)，但晒在(zai)身(shen)上大多(duo)不会感到炎热。使用中空(kong)(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)幕墙(qiang)(qiang)的房间可以(yi)做到冬暖夏凉，很大地改(gai)善了生活环境。

基本分类

框(kuang)支撑玻(bo)璃幕(mu)墙是玻(bo)璃面(mian)板周边由金(jin)属框(kuang)架支撑的玻(bo)璃幕(mu)墙，主要包括：

玻(bo)璃幕(mu)墙是金属框架构件显露在外表面(mian)(mian)的(de)玻(bo)璃幕(mu)墙。它以特殊(shu)断(duan)面(mian)(mian)的(de)铝合金型(xing)(xing)材为(wei)框架，玻(bo)璃面(mian)(mian)板全嵌入型(xing)(xing)材的(de)凹槽内(nei)。其特点(dian)在于(yu)铝合金型(xing)(xing)材本身兼有骨架结构和固定玻(bo)璃的(de)双重作用(yong)。

玻(bo)璃幕墙(qiang)是传统的形式，应用(yong)广泛(fan)，工作性能(neng)可靠。相对于(yu)隐框玻(bo)璃幕墙(qiang)，更易满足施工技术水平要求。
