玻璃幕墙，是指由支承结(jie)(jie)构(gou)体(ti)(ti)系可相对主体(ti)(ti)结(jie)(jie)构(gou)有(you)一(yi)定位移能力、不(bu)分担主体(ti)(ti)结(jie)(jie)构(gou)所受作用的(de)建(jian)筑外围护结(jie)(jie)构(gou)或装饰结(jie)(jie)构(gou)。墙(qiang)体(ti)(ti)有(you)单层和双层玻(bo)璃(li)两种(zhong)。玻(bo)璃(li)幕墙(qiang)是一(yi)种(zhong)美观新颖的(de)建(jian)筑墙(qiang)体(ti)(ti)装饰方法，是现代(dai)主义高层建(jian)筑时代(dai)的(de)显著(zhu)特征。

功能作用

现代化(hua)高(gao)层(ceng)(ceng)(ceng)(ceng)建筑的玻(bo)(bo)璃(li)(li)(li)(li)(li)(li)(li)幕(mu)墙采用了由镜面(mian)玻(bo)(bo)璃(li)(li)(li)(li)(li)(li)(li)与普通玻(bo)(bo)璃(li)(li)(li)(li)(li)(li)(li)组合，隔(ge)层(ceng)(ceng)(ceng)(ceng)充入(ru)干燥空(kong)(kong)(kong)气或惰性气体的中(zhong)空(kong)(kong)(kong)玻(bo)(bo)璃(li)(li)(li)(li)(li)(li)(li)。中(zhong)空(kong)(kong)(kong)玻(bo)(bo)璃(li)(li)(li)(li)(li)(li)(li)有(you)两(liang)层(ceng)(ceng)(ceng)(ceng)和(he)三层(ceng)(ceng)(ceng)(ceng)之分，两(liang)层(ceng)(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)璃(li)(li)(li)(li)(li)(li)(li)由两(liang)层(ceng)(ceng)(ceng)(ceng)玻(bo)(bo)璃(li)(li)(li)(li)(li)(li)(li)加密封框(kuang)架，形成一个夹(jia)层(ceng)(ceng)(ceng)(ceng)空(kong)(kong)(kong)间(jian)；三层(ceng)(ceng)(ceng)(ceng)玻(bo)(bo)璃(li)(li)(li)(li)(li)(li)(li)则是由三层(ceng)(ceng)(ceng)(ceng)玻(bo)(bo)璃(li)(li)(li)(li)(li)(li)(li)构(gou)成两(liang)个夹(jia)层(ceng)(ceng)(ceng)(ceng)空(kong)(kong)(kong)间(jian)。中(zhong)空(kong)(kong)(kong)玻(bo)(bo)璃(li)(li)(li)(li)(li)(li)(li)具有(you)隔(ge)音(yin)、隔(ge)热(re)、防结霜、防潮、抗风压强度(du)大等优点(dian)。据测量，当室(shi)外温(wen)度(du)为(wei)－10℃时，单层(ceng)(ceng)(ceng)(ceng)玻(bo)(bo)璃(li)(li)(li)(li)(li)(li)(li)窗前的温(wen)度(du)为(wei)－2℃，而使用三层(ceng)(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)璃(li)(li)(li)(li)(li)(li)(li)的室(shi)内温(wen)度(du)为(wei)13℃。而在(zai)炎热(re)夏天，双层(ceng)(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)(kong)玻(bo)(bo)璃(li)(li)(li)(li)(li)(li)(li)可以挡住(zhu)90的太阳(yang)(yang)辐射(she)热(re)。阳(yang)(yang)光依然可以透过玻(bo)(bo)璃(li)(li)(li)(li)(li)(li)(li)幕(mu)墙，但晒在(zai)身上大多不会感到炎热(re)。使用中(zhong)空(kong)(kong)(kong)玻(bo)(bo)璃(li)(li)(li)(li)(li)(li)(li)幕(mu)墙的房(fang)间(jian)可以做到冬暖夏凉，很大地改善了生(sheng)活环境。

基本分类

框(kuang)支(zhi)撑(cheng)玻(bo)璃幕(mu)墙是玻(bo)璃面板(ban)周边由金(jin)属框(kuang)架支(zhi)撑(cheng)的(de)玻(bo)璃幕(mu)墙，主要包括：

玻(bo)(bo)璃(li)(li)幕(mu)墙是(shi)金(jin)属框架(jia)构件显露在(zai)外表面(mian)的(de)玻(bo)(bo)璃(li)(li)幕(mu)墙。它以特殊断面(mian)的(de)铝(lv)合金(jin)型(xing)材(cai)(cai)为框架(jia)，玻(bo)(bo)璃(li)(li)面(mian)板(ban)全嵌入(ru)型(xing)材(cai)(cai)的(de)凹槽内(nei)。其特点在(zai)于(yu)铝(lv)合金(jin)型(xing)材(cai)(cai)本身兼有(you)骨架(jia)结构和固定玻(bo)(bo)璃(li)(li)的(de)双重(zhong)作(zuo)用。

玻(bo)璃幕墙是传统的形式(shi)，应用广泛，工(gong)作(zuo)性能可靠。相对于隐框玻(bo)璃幕墙，更易(yi)满足施工(gong)技术水平(ping)要求。
