玻璃(li)幕墙(qiang)，是指(zhi)由(you)支承结构(gou)(gou)体(ti)(ti)(ti)系(xi)可相(xiang)对(dui)主体(ti)(ti)(ti)结构(gou)(gou)有(you)一定(ding)位移能力、不分担主体(ti)(ti)(ti)结构(gou)(gou)所受作用的(de)建筑外围(wei)护结构(gou)(gou)或装饰(shi)结构(gou)(gou)。墙(qiang)(qiang)体(ti)(ti)(ti)有(you)单(dan)层和双层玻璃两种。玻璃幕墙(qiang)(qiang)是一种美(mei)观(guan)新(xin)颖(ying)的(de)建筑墙(qiang)(qiang)体(ti)(ti)(ti)装饰(shi)方法(fa)，是现代主义(yi)高层建筑时代的(de)显(xian)著特(te)征。

功能作用

现代化高层(ceng)建筑的玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)幕墙(qiang)采用(yong)(yong)了(le)由镜面玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)与(yu)普(pu)通(tong)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)组合，隔层(ceng)充入干燥(zao)空(kong)(kong)气(qi)或惰(duo)性气(qi)体(ti)的中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)。中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)有(you)两(liang)层(ceng)和(he)三(san)层(ceng)之分(fen)，两(liang)层(ceng)中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)由两(liang)层(ceng)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)加密封(feng)框架，形(xing)成(cheng)一个夹层(ceng)空(kong)(kong)间；三(san)层(ceng)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)则是(shi)由三(san)层(ceng)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)构成(cheng)两(liang)个夹层(ceng)空(kong)(kong)间。中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)具有(you)隔音(yin)、隔热、防(fang)结霜、防(fang)潮、抗风压强度大(da)等优点。据测量(liang)，当室外温度为(wei)－10℃时，单层(ceng)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)窗前的温度为(wei)－2℃，而(er)使用(yong)(yong)三(san)层(ceng)中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)的室内温度为(wei)13℃。而(er)在(zai)炎热夏天，双层(ceng)中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)可(ke)以挡(dang)住(zhu)90的太阳辐射热。阳光依然可(ke)以透过玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)幕墙(qiang)，但晒(shai)在(zai)身上大(da)多不(bu)会感(gan)到(dao)炎热。使用(yong)(yong)中(zhong)(zhong)空(kong)(kong)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)(li)(li)幕墙(qiang)的房间可(ke)以做到(dao)冬(dong)暖夏凉，很大(da)地改(gai)善了(le)生活环(huan)境。

基本分类

框支(zhi)撑玻(bo)(bo)璃幕墙(qiang)是玻(bo)(bo)璃面(mian)板周边(bian)由金(jin)属框架支(zhi)撑的玻(bo)(bo)璃幕墙(qiang)，主(zhu)要(yao)包括：

玻(bo)璃幕墙(qiang)是金(jin)属(shu)框架(jia)构(gou)件(jian)显露(lu)在外表面的玻(bo)璃幕墙(qiang)。它(ta)以特殊(shu)断面的铝合(he)金(jin)型(xing)材为框架(jia)，玻(bo)璃面板全(quan)嵌入型(xing)材的凹槽(cao)内(nei)。其特点在于(yu)铝合(he)金(jin)型(xing)材本身兼有骨架(jia)结构(gou)和固定玻(bo)璃的双重(zhong)作用。

玻(bo)璃(li)幕(mu)墙(qiang)是(shi)传(chuan)统(tong)的形(xing)式，应用广泛(fan)，工作性能(neng)可靠。相对于隐框玻(bo)璃(li)幕(mu)墙(qiang)，更易满足施工技术水平要(yao)求。
