玻(bo)璃幕墙(qiang)，是指由支承(cheng)结(jie)构(gou)(gou)体(ti)系可相对主(zhu)体(ti)结(jie)构(gou)(gou)有一定位移能力、不分担主(zhu)体(ti)结(jie)构(gou)(gou)所受作用的(de)建(jian)(jian)筑外围护结(jie)构(gou)(gou)或装饰(shi)结(jie)构(gou)(gou)。墙体(ti)有单层和(he)双层玻璃两(liang)种。玻璃幕(mu)墙是一种美观(guan)新颖的(de)建(jian)(jian)筑墙体(ti)装饰(shi)方法，是现代主(zhu)义高层建(jian)(jian)筑时代的(de)显著特(te)征。

功能作用

现代(dai)化(hua)高(gao)层(ceng)(ceng)(ceng)建(jian)筑的(de)玻(bo)(bo)(bo)璃(li)(li)幕墙(qiang)采用了由(you)镜(jing)面玻(bo)(bo)(bo)璃(li)(li)与(yu)普(pu)通玻(bo)(bo)(bo)璃(li)(li)组合，隔层(ceng)(ceng)(ceng)充入干(gan)燥空(kong)(kong)(kong)气或惰性气体(ti)的(de)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)。中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)有(you)两层(ceng)(ceng)(ceng)和三层(ceng)(ceng)(ceng)之分，两层(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)由(you)两层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)璃(li)(li)加密封(feng)框架，形(xing)成(cheng)(cheng)一个夹(jia)层(ceng)(ceng)(ceng)空(kong)(kong)(kong)间；三层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)璃(li)(li)则是由(you)三层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)璃(li)(li)构成(cheng)(cheng)两个夹(jia)层(ceng)(ceng)(ceng)空(kong)(kong)(kong)间。中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)具有(you)隔音、隔热(re)(re)、防(fang)结霜、防(fang)潮、抗风压(ya)强度(du)大等优点。据测(ce)量，当室外温度(du)为－10℃时，单层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)璃(li)(li)窗前(qian)的(de)温度(du)为－2℃，而(er)使用三层(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)的(de)室内(nei)温度(du)为13℃。而(er)在炎热(re)(re)夏天，双层(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)可(ke)以(yi)挡(dang)住(zhu)90的(de)太阳(yang)(yang)辐射(she)热(re)(re)。阳(yang)(yang)光依然可(ke)以(yi)透过(guo)玻(bo)(bo)(bo)璃(li)(li)幕墙(qiang)，但(dan)晒在身上大多不会感到炎热(re)(re)。使用中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)幕墙(qiang)的(de)房间可(ke)以(yi)做到冬暖夏凉，很大地改善了生(sheng)活环境。

基本分类

框支撑(cheng)玻璃(li)幕(mu)墙(qiang)是玻璃(li)面板(ban)周(zhou)边(bian)由金属框架支撑(cheng)的(de)玻璃(li)幕(mu)墙(qiang)，主(zhu)要包括：

玻璃(li)(li)幕(mu)(mu)墙(qiang)是金属框架(jia)构(gou)(gou)件(jian)显(xian)露(lu)在外表面的(de)玻璃(li)(li)幕(mu)(mu)墙(qiang)。它(ta)以特(te)殊(shu)断面的(de)铝合金型(xing)(xing)材(cai)为框架(jia)，玻璃(li)(li)面板全嵌入(ru)型(xing)(xing)材(cai)的(de)凹槽(cao)内。其特(te)点在于铝合金型(xing)(xing)材(cai)本身兼有骨架(jia)结构(gou)(gou)和(he)固定玻璃(li)(li)的(de)双重作用。

玻璃幕墙是传统的形式，应用广泛(fan)，工作(zuo)性(xing)能(neng)可靠。相对于隐框玻璃幕墙，更易满足(zu)施工技术水平要求。
