玻璃(li)幕墙，是(shi)(shi)指由支(zhi)承结(jie)(jie)构(gou)体(ti)(ti)系可相对主(zhu)体(ti)(ti)结(jie)(jie)构(gou)有一(yi)定位(wei)移能力、不分担(dan)主(zhu)体(ti)(ti)结(jie)(jie)构(gou)所受作用的建(jian)(jian)(jian)筑外围护结(jie)(jie)构(gou)或(huo)装饰结(jie)(jie)构(gou)。墙(qiang)(qiang)体(ti)(ti)有单层和(he)双层玻璃(li)两(liang)种。玻璃(li)幕墙(qiang)(qiang)是(shi)(shi)一(yi)种美观新颖的建(jian)(jian)(jian)筑墙(qiang)(qiang)体(ti)(ti)装饰方法(fa)，是(shi)(shi)现(xian)代主(zhu)义(yi)高层建(jian)(jian)(jian)筑时代的显(xian)著(zhu)特征。

功能作用

现代化(hua)高层(ceng)(ceng)建(jian)筑的玻(bo)(bo)(bo)璃(li)(li)(li)幕墙(qiang)采(cai)用(yong)了(le)由(you)(you)镜面(mian)玻(bo)(bo)(bo)璃(li)(li)(li)与(yu)普通玻(bo)(bo)(bo)璃(li)(li)(li)组合，隔(ge)层(ceng)(ceng)充入干(gan)燥(zao)空(kong)(kong)(kong)气(qi)(qi)或惰性气(qi)(qi)体的中(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)(li)。中(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)(li)有两(liang)(liang)层(ceng)(ceng)和三层(ceng)(ceng)之分，两(liang)(liang)层(ceng)(ceng)中(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)(li)由(you)(you)两(liang)(liang)层(ceng)(ceng)玻(bo)(bo)(bo)璃(li)(li)(li)加密封(feng)框(kuang)架，形(xing)成一(yi)个(ge)夹层(ceng)(ceng)空(kong)(kong)(kong)间(jian)；三层(ceng)(ceng)玻(bo)(bo)(bo)璃(li)(li)(li)则是由(you)(you)三层(ceng)(ceng)玻(bo)(bo)(bo)璃(li)(li)(li)构成两(liang)(liang)个(ge)夹层(ceng)(ceng)空(kong)(kong)(kong)间(jian)。中(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)(li)具有隔(ge)音、隔(ge)热、防结霜、防潮、抗(kang)风压强(qiang)度(du)大(da)(da)等(deng)优点。据测量，当室外温(wen)(wen)度(du)为(wei)－10℃时，单层(ceng)(ceng)玻(bo)(bo)(bo)璃(li)(li)(li)窗前的温(wen)(wen)度(du)为(wei)－2℃，而使用(yong)三层(ceng)(ceng)中(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)(li)的室内温(wen)(wen)度(du)为(wei)13℃。而在炎(yan)热夏天(tian)，双层(ceng)(ceng)中(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)(li)可以挡住90的太(tai)阳辐射热。阳光依然可以透过玻(bo)(bo)(bo)璃(li)(li)(li)幕墙(qiang)，但晒(shai)在身上(shang)大(da)(da)多不会感到炎(yan)热。使用(yong)中(zhong)(zhong)空(kong)(kong)(kong)玻(bo)(bo)(bo)璃(li)(li)(li)幕墙(qiang)的房间(jian)可以做到冬(dong)暖夏凉(liang)，很大(da)(da)地改善了(le)生(sheng)活(huo)环境。

基本分类

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

玻(bo)璃(li)(li)幕墙(qiang)是金属框架构件(jian)显露在外表面(mian)的(de)玻(bo)璃(li)(li)幕墙(qiang)。它(ta)以特殊断(duan)面(mian)的(de)铝(lv)合金型材为框架，玻(bo)璃(li)(li)面(mian)板全嵌入型材的(de)凹槽内。其特点在于铝(lv)合金型材本身兼(jian)有骨架结构和固定(ding)玻(bo)璃(li)(li)的(de)双重作用。

玻璃幕墙是(shi)传统的形式(shi)，应用广泛(fan)，工作性能(neng)可(ke)靠。相(xiang)对于(yu)隐框玻璃幕墙，更易满足施工技(ji)术(shu)水平(ping)要求。
