玻璃幕墙(qiang)，是(shi)指由支承结构(gou)(gou)(gou)体(ti)(ti)系(xi)可相(xiang)对主(zhu)体(ti)(ti)结构(gou)(gou)(gou)有一定位移(yi)能力(li)、不(bu)分担主(zhu)体(ti)(ti)结构(gou)(gou)(gou)所受作用(yong)的建筑外围护结构(gou)(gou)(gou)或装(zhuang)饰结构(gou)(gou)(gou)。墙体(ti)(ti)有单层(ceng)和双层(ceng)玻璃两种。玻璃幕墙是(shi)一种美观新(xin)颖的建筑墙体(ti)(ti)装(zhuang)饰方法，是(shi)现代主(zhu)义高(gao)层(ceng)建筑时代的显著特征。

功能作用

现代化高层(ceng)(ceng)(ceng)建筑的(de)玻(bo)(bo)璃(li)(li)幕(mu)墙采用(yong)了(le)由镜面玻(bo)(bo)璃(li)(li)与(yu)普通玻(bo)(bo)璃(li)(li)组(zu)合，隔(ge)(ge)层(ceng)(ceng)(ceng)充入干燥空(kong)(kong)(kong)气或惰性(xing)气体的(de)中(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)璃(li)(li)。中(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)璃(li)(li)有两层(ceng)(ceng)(ceng)和三层(ceng)(ceng)(ceng)之分，两层(ceng)(ceng)(ceng)中(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)璃(li)(li)由两层(ceng)(ceng)(ceng)玻(bo)(bo)璃(li)(li)加密封框(kuang)架，形成(cheng)一个夹层(ceng)(ceng)(ceng)空(kong)(kong)(kong)间；三层(ceng)(ceng)(ceng)玻(bo)(bo)璃(li)(li)则是由三层(ceng)(ceng)(ceng)玻(bo)(bo)璃(li)(li)构成(cheng)两个夹层(ceng)(ceng)(ceng)空(kong)(kong)(kong)间。中(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)璃(li)(li)具有隔(ge)(ge)音、隔(ge)(ge)热、防结霜、防潮、抗风(feng)压强度大等优点(dian)。据测量，当(dang)室外温度为－10℃时，单层(ceng)(ceng)(ceng)玻(bo)(bo)璃(li)(li)窗前的(de)温度为－2℃，而(er)使用(yong)三层(ceng)(ceng)(ceng)中(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)璃(li)(li)的(de)室内(nei)温度为13℃。而(er)在(zai)炎(yan)热夏(xia)天，双层(ceng)(ceng)(ceng)中(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)璃(li)(li)可(ke)以(yi)挡住(zhu)90的(de)太(tai)阳辐射热。阳光依然可(ke)以(yi)透过玻(bo)(bo)璃(li)(li)幕(mu)墙，但晒在(zai)身上(shang)大多不会感到炎(yan)热。使用(yong)中(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)璃(li)(li)幕(mu)墙的(de)房间可(ke)以(yi)做到冬暖夏(xia)凉(liang)，很(hen)大地改(gai)善了(le)生(sheng)活环境。

基本分类

框支撑玻(bo)璃幕(mu)墙是玻(bo)璃面(mian)板周边由金(jin)属(shu)框架(jia)支撑的(de)玻(bo)璃幕(mu)墙，主要包括(kuo)：

玻璃(li)(li)幕墙(qiang)是金(jin)属框架(jia)构件显露在外表面(mian)的玻璃(li)(li)幕墙(qiang)。它以特(te)殊(shu)断(duan)面(mian)的铝合金(jin)型(xing)(xing)材(cai)(cai)为(wei)框架(jia)，玻璃(li)(li)面(mian)板全嵌(qian)入(ru)型(xing)(xing)材(cai)(cai)的凹槽内。其特(te)点(dian)在于铝合金(jin)型(xing)(xing)材(cai)(cai)本身(shen)兼有骨架(jia)结构和固定(ding)玻璃(li)(li)的双重作用。

玻璃幕墙(qiang)是(shi)传统的(de)形式(shi)，应用广泛，工作性能可靠。相对于隐框玻璃幕墙(qiang)，更易(yi)满足施工技(ji)术水平要求。
