玻(bo)璃幕墙，是指由支承结(jie)(jie)(jie)构(gou)体(ti)(ti)系可相(xiang)对主体(ti)(ti)结(jie)(jie)(jie)构(gou)有一(yi)定位移(yi)能力、不(bu)分担主体(ti)(ti)结(jie)(jie)(jie)构(gou)所受(shou)作用的(de)建筑(zhu)外围(wei)护结(jie)(jie)(jie)构(gou)或装饰结(jie)(jie)(jie)构(gou)。墙(qiang)体(ti)(ti)有单层(ceng)(ceng)和双层(ceng)(ceng)玻璃(li)两种。玻璃(li)幕墙(qiang)是一(yi)种美观新颖(ying)的(de)建筑(zhu)墙(qiang)体(ti)(ti)装饰方法(fa)，是现代主义高层(ceng)(ceng)建筑(zhu)时代的(de)显著特征。

功能作用

现代(dai)化(hua)高层(ceng)(ceng)(ceng)建筑的(de)(de)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)幕墙(qiang)采用(yong)了(le)由镜面玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)与普通玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)组合(he)，隔层(ceng)(ceng)(ceng)充入干燥空(kong)(kong)(kong)气或(huo)惰(duo)性气体的(de)(de)中(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)。中(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)有两(liang)(liang)(liang)层(ceng)(ceng)(ceng)和三层(ceng)(ceng)(ceng)之分，两(liang)(liang)(liang)层(ceng)(ceng)(ceng)中(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)由两(liang)(liang)(liang)层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)加密封框架，形成一(yi)个(ge)夹层(ceng)(ceng)(ceng)空(kong)(kong)(kong)间；三层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)则是(shi)由三层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)构成两(liang)(liang)(liang)个(ge)夹层(ceng)(ceng)(ceng)空(kong)(kong)(kong)间。中(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)具有隔音、隔热(re)、防结霜、防潮(chao)、抗风(feng)压强度(du)(du)大(da)等优点。据测量，当(dang)室外温度(du)(du)为－10℃时，单层(ceng)(ceng)(ceng)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)窗(chuang)前的(de)(de)温度(du)(du)为－2℃，而使(shi)用(yong)三层(ceng)(ceng)(ceng)中(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)的(de)(de)室内温度(du)(du)为13℃。而在炎热(re)夏天，双(shuang)层(ceng)(ceng)(ceng)中(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)可以挡住90的(de)(de)太阳(yang)辐射热(re)。阳(yang)光依然(ran)可以透过玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)幕墙(qiang)，但(dan)晒在身(shen)上(shang)大(da)多不会感到炎热(re)。使(shi)用(yong)中(zhong)(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)幕墙(qiang)的(de)(de)房间可以做(zuo)到冬暖夏凉(liang)，很大(da)地改善(shan)了(le)生活环境(jing)。

基本分类

框支撑玻(bo)璃幕墙是(shi)玻(bo)璃面板周边由金属框架支撑的玻(bo)璃幕墙，主要包括：

玻(bo)(bo)(bo)璃(li)幕墙是(shi)金属框架构(gou)件显露在外表面(mian)的玻(bo)(bo)(bo)璃(li)幕墙。它以特(te)(te)殊断面(mian)的铝合金型(xing)材为框架，玻(bo)(bo)(bo)璃(li)面(mian)板全(quan)嵌入型(xing)材的凹槽内。其特(te)(te)点在于(yu)铝合金型(xing)材本(ben)身兼有骨(gu)架结构(gou)和固定玻(bo)(bo)(bo)璃(li)的双重作用。

玻璃幕墙(qiang)是传统的形(xing)式，应用广(guang)泛，工(gong)作性能可(ke)靠。相对于隐框玻璃幕墙(qiang)，更易(yi)满足施工(gong)技术水平要求。
