玻璃幕墙，是指(zhi)由(you)支承结构体(ti)系(xi)可相(xiang)对主(zhu)体(ti)结构有一定位移能力、不分担主(zhu)体(ti)结构所受作用的(de)建筑外(wai)围护结构或装饰结构。墙(qiang)体(ti)有单层(ceng)和双(shuang)层(ceng)玻璃两种。玻璃幕墙(qiang)是一种美观新颖的(de)建筑墙(qiang)体(ti)装饰方法，是现代(dai)主(zhu)义高层(ceng)建筑时代(dai)的(de)显著特征。

功能作用

现代化高层(ceng)(ceng)(ceng)(ceng)(ceng)建筑(zhu)的(de)(de)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)(li)幕墙(qiang)采用(yong)了由镜面玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)(li)与普通玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)(li)组合，隔(ge)层(ceng)(ceng)(ceng)(ceng)(ceng)充入干燥空(kong)(kong)(kong)气(qi)或(huo)惰(duo)性气(qi)体(ti)的(de)(de)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)(li)。中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)(li)有两(liang)层(ceng)(ceng)(ceng)(ceng)(ceng)和三(san)(san)(san)层(ceng)(ceng)(ceng)(ceng)(ceng)之分，两(liang)层(ceng)(ceng)(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)(li)由两(liang)层(ceng)(ceng)(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)(li)加(jia)密封框(kuang)架，形成一个(ge)夹层(ceng)(ceng)(ceng)(ceng)(ceng)空(kong)(kong)(kong)间；三(san)(san)(san)层(ceng)(ceng)(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)(li)则是(shi)由三(san)(san)(san)层(ceng)(ceng)(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)(li)构成两(liang)个(ge)夹层(ceng)(ceng)(ceng)(ceng)(ceng)空(kong)(kong)(kong)间。中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)(li)具有隔(ge)音(yin)、隔(ge)热(re)、防结霜、防潮、抗(kang)风压强度(du)大(da)等(deng)优点。据测量，当室外温度(du)为(wei)－10℃时(shi)，单层(ceng)(ceng)(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)(li)窗前的(de)(de)温度(du)为(wei)－2℃，而使用(yong)三(san)(san)(san)层(ceng)(ceng)(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)(li)的(de)(de)室内温度(du)为(wei)13℃。而在炎热(re)夏(xia)天，双(shuang)层(ceng)(ceng)(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)(li)可(ke)以挡住90的(de)(de)太阳辐射热(re)。阳光(guang)依(yi)然可(ke)以透过(guo)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)(li)幕墙(qiang)，但晒在身上大(da)多(duo)不会(hui)感到炎热(re)。使用(yong)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)(li)幕墙(qiang)的(de)(de)房间可(ke)以做到冬暖夏(xia)凉，很大(da)地改(gai)善了生活环境。

基本分类

框(kuang)支撑玻(bo)璃(li)幕(mu)墙是(shi)玻(bo)璃(li)面板(ban)周边由金属框(kuang)架支撑的玻(bo)璃(li)幕(mu)墙，主要包(bao)括：

玻(bo)(bo)璃(li)幕墙是金(jin)(jin)属框架(jia)(jia)构件显露在外表(biao)面(mian)的玻(bo)(bo)璃(li)幕墙。它(ta)以(yi)特殊断面(mian)的铝(lv)合金(jin)(jin)型(xing)材(cai)(cai)为框架(jia)(jia)，玻(bo)(bo)璃(li)面(mian)板(ban)全嵌入型(xing)材(cai)(cai)的凹(ao)槽内。其特点在于铝(lv)合金(jin)(jin)型(xing)材(cai)(cai)本(ben)身兼有骨架(jia)(jia)结构和固(gu)定玻(bo)(bo)璃(li)的双重作用。

玻(bo)璃幕墙是传统的形(xing)式，应用广泛，工(gong)作性(xing)能(neng)可(ke)靠。相对于隐(yin)框玻(bo)璃幕墙，更(geng)易满足施工(gong)技术水平要求。
