玻璃幕墙(qiang)，是指(zhi)由支承(cheng)结构体(ti)系可相对(dui)主体(ti)结构有一定位移(yi)能力、不分担主体(ti)结构所受作用的建筑外围护结构或装饰(shi)结构。墙体(ti)有单层(ceng)和双(shuang)层(ceng)玻(bo)璃两种。玻(bo)璃幕墙是一种美观(guan)新颖的建筑墙体(ti)装饰(shi)方法(fa)，是现代(dai)主义高(gao)层(ceng)建筑时(shi)代(dai)的显著特征。

功能作用

现代化高层(ceng)(ceng)(ceng)建筑(zhu)的(de)玻(bo)(bo)(bo)(bo)璃(li)幕(mu)墙采(cai)用(yong)(yong)了(le)由(you)镜(jing)面玻(bo)(bo)(bo)(bo)璃(li)与(yu)普(pu)通玻(bo)(bo)(bo)(bo)璃(li)组合，隔层(ceng)(ceng)(ceng)充入干燥空(kong)(kong)气(qi)或惰性气(qi)体的(de)中(zhong)空(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)。中(zhong)空(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)有两(liang)(liang)层(ceng)(ceng)(ceng)和三层(ceng)(ceng)(ceng)之分，两(liang)(liang)层(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)由(you)两(liang)(liang)层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)加密封框架(jia)，形成(cheng)一(yi)个(ge)夹层(ceng)(ceng)(ceng)空(kong)(kong)间(jian)；三层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)则(ze)是由(you)三层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)构成(cheng)两(liang)(liang)个(ge)夹层(ceng)(ceng)(ceng)空(kong)(kong)间(jian)。中(zhong)空(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)具有隔音、隔热(re)(re)(re)、防结霜、防潮、抗风压强度(du)(du)大(da)等优点(dian)。据测(ce)量，当室外温(wen)(wen)度(du)(du)为(wei)－10℃时，单层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)窗前的(de)温(wen)(wen)度(du)(du)为(wei)－2℃，而(er)使(shi)用(yong)(yong)三层(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)的(de)室内温(wen)(wen)度(du)(du)为(wei)13℃。而(er)在炎热(re)(re)(re)夏(xia)天，双层(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)可以挡住90的(de)太阳辐射热(re)(re)(re)。阳光依(yi)然可以透(tou)过玻(bo)(bo)(bo)(bo)璃(li)幕(mu)墙，但(dan)晒在身上大(da)多不会(hui)感到炎热(re)(re)(re)。使(shi)用(yong)(yong)中(zhong)空(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)幕(mu)墙的(de)房间(jian)可以做到冬暖夏(xia)凉，很大(da)地改善了(le)生活环境。

基本分类

框(kuang)支撑玻(bo)璃幕(mu)墙(qiang)是玻(bo)璃面板周边由金属框(kuang)架支撑的玻(bo)璃幕(mu)墙(qiang)，主要包(bao)括：

玻(bo)璃幕墙是金(jin)属框架(jia)构件(jian)显露在外表面(mian)的(de)玻(bo)璃幕墙。它以(yi)特(te)殊断面(mian)的(de)铝合金(jin)型材(cai)为框架(jia)，玻(bo)璃面(mian)板全嵌入(ru)型材(cai)的(de)凹槽(cao)内。其(qi)特(te)点在于(yu)铝合金(jin)型材(cai)本身兼有骨架(jia)结(jie)构和(he)固定(ding)玻(bo)璃的(de)双重作用。

玻(bo)璃幕墙是传(chuan)统(tong)的形式(shi)，应用广泛，工作性能可(ke)靠。相对于隐框玻(bo)璃幕墙，更易满足(zu)施工技术水平要求。
