功能作用

现代化(hua)高层(ceng)(ceng)(ceng)(ceng)(ceng)建(jian)筑(zhu)的(de)(de)(de)(de)玻璃(li)(li)(li)(li)幕(mu)(mu)墙采用了由镜面(mian)玻璃(li)(li)(li)(li)与(yu)普通(tong)玻璃(li)(li)(li)(li)组合，隔(ge)层(ceng)(ceng)(ceng)(ceng)(ceng)充入干燥空(kong)(kong)(kong)气或惰性气体的(de)(de)(de)(de)中(zhong)空(kong)(kong)(kong)玻璃(li)(li)(li)(li)。中(zhong)空(kong)(kong)(kong)玻璃(li)(li)(li)(li)有两(liang)层(ceng)(ceng)(ceng)(ceng)(ceng)和(he)三层(ceng)(ceng)(ceng)(ceng)(ceng)之分，两(liang)层(ceng)(ceng)(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)(kong)玻璃(li)(li)(li)(li)由两(liang)层(ceng)(ceng)(ceng)(ceng)(ceng)玻璃(li)(li)(li)(li)加密封(feng)框架，形成一(yi)个夹层(ceng)(ceng)(ceng)(ceng)(ceng)空(kong)(kong)(kong)间；三层(ceng)(ceng)(ceng)(ceng)(ceng)玻璃(li)(li)(li)(li)则(ze)是由三层(ceng)(ceng)(ceng)(ceng)(ceng)玻璃(li)(li)(li)(li)构成两(liang)个夹层(ceng)(ceng)(ceng)(ceng)(ceng)空(kong)(kong)(kong)间。中(zhong)空(kong)(kong)(kong)玻璃(li)(li)(li)(li)具有隔(ge)音、隔(ge)热(re)、防(fang)结霜、防(fang)潮、抗风压强(qiang)度大等优点(dian)。据测量，当(dang)室外温(wen)(wen)度为(wei)－10℃时，单(dan)层(ceng)(ceng)(ceng)(ceng)(ceng)玻璃(li)(li)(li)(li)窗前的(de)(de)(de)(de)温(wen)(wen)度为(wei)－2℃，而使用三层(ceng)(ceng)(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)(kong)玻璃(li)(li)(li)(li)的(de)(de)(de)(de)室内温(wen)(wen)度为(wei)13℃。而在(zai)(zai)炎热(re)夏(xia)天，双层(ceng)(ceng)(ceng)(ceng)(ceng)中(zhong)空(kong)(kong)(kong)玻璃(li)(li)(li)(li)可(ke)以挡住90的(de)(de)(de)(de)太阳辐射热(re)。阳光依然可(ke)以透过玻璃(li)(li)(li)(li)幕(mu)(mu)墙，但晒在(zai)(zai)身上(shang)大多不(bu)会(hui)感到炎热(re)。使用中(zhong)空(kong)(kong)(kong)玻璃(li)(li)(li)(li)幕(mu)(mu)墙的(de)(de)(de)(de)房(fang)间可(ke)以做到冬暖夏(xia)凉，很(hen)大地改善(shan)了生活环境。

基本分类

框支撑玻(bo)(bo)璃(li)幕墙是玻(bo)(bo)璃(li)面板周边由(you)金属(shu)框架支撑的(de)玻(bo)(bo)璃(li)幕墙，主(zhu)要包括(kuo)：

玻(bo)璃幕(mu)墙(qiang)(qiang)是金(jin)属框架(jia)构件显(xian)露在外表(biao)面(mian)的玻(bo)璃幕(mu)墙(qiang)(qiang)。它以(yi)特殊断(duan)面(mian)的铝(lv)合金(jin)型(xing)材(cai)(cai)为框架(jia)，玻(bo)璃面(mian)板全嵌入型(xing)材(cai)(cai)的凹槽内。其特点在于铝(lv)合金(jin)型(xing)材(cai)(cai)本身(shen)兼有骨架(jia)结构和固(gu)定玻(bo)璃的双重作用。

玻璃幕(mu)(mu)墙(qiang)是传统的(de)形(xing)式，应用(yong)广泛，工(gong)作性能可靠。相(xiang)对(dui)于隐框玻璃幕(mu)(mu)墙(qiang)，更易(yi)满足(zu)施工(gong)技术水平(ping)要(yao)求。
