玻(bo)璃(li)幕墻(qiang)(qiang)(ref1ecti0ng1asscurtainwa11),是(shi)(shi)指(zhi)由(you)支承結構(gou)(gou)體(ti)系與玻(bo)璃(li)組成的(de)、可相對(dui)主(zhu)體(ti)結構(gou)(gou)有(you)一(yi)定位移(yi)能力、不分擔主(zhu)體(ti)結構(gou)(gou)所受作(zuo)用的(de)建(jian)筑(zhu)外圍(wei)護結構(gou)(gou)或裝飾結構(gou)(gou).墻(qiang)(qiang)體(ti)有(you)單(dan)層(ceng)(ceng)和雙層(ceng)(ceng)玻(bo)璃(li)兩種(zhong)(zhong).玻(bo)璃(li)幕墻(qiang)(qiang)是(shi)(shi)一(yi)種(zhong)(zhong)美觀新(xin)穎的(de)建(jian)筑(zhu)墻(qiang)(qiang)體(ti)裝飾方(fang)法,是(shi)(shi)現代主(zhu)義(yi)高(gao)層(ceng)(ceng)建(jian)筑(zhu)時代的(de)顯著特征.2013年(nian)(nian)據鳥類保護志愿(yuan)者組織(zhi)F1AP(Fata11ightAwarenessPr0gram)統計,僅在多倫多一(yi)地,每年(nian)(nian)就有(you)一(yi)百萬到九百萬的(de)候(hou)鳥死于這些玻(bo)璃(li)幕墻(qiang)(qiang).現代化高(gao)層(ceng)(ceng)建(jian)筑(zhu)的(de)玻(bo)璃(li)幕墻(qiang)(qiang)采用了由(you)鏡面玻(bo)璃(li)與普通玻(bo)璃(li)組合(he),隔層(ceng)(ceng)充入干燥空氣或惰性氣體(ti)的(de)中(zhong)空玻(bo)璃(li).

    中(zhong)(zhong)空(kong)玻(bo)(bo)璃(li)(li)(li)有兩(liang)層(ceng)(ceng)(ceng)和三(san)(san)層(ceng)(ceng)(ceng)之分(fen),兩(liang)層(ceng)(ceng)(ceng)中(zhong)(zhong)空(kong)玻(bo)(bo)璃(li)(li)(li)由(you)(you)兩(liang)層(ceng)(ceng)(ceng)玻(bo)(bo)璃(li)(li)(li)加密封框(kuang)架(jia),形(xing)成一個(ge)夾(jia)(jia)層(ceng)(ceng)(ceng)空(kong)間.三(san)(san)層(ceng)(ceng)(ceng)玻(bo)(bo)璃(li)(li)(li)則是(shi)由(you)(you)三(san)(san)層(ceng)(ceng)(ceng)玻(bo)(bo)璃(li)(li)(li)構成兩(liang)個(ge)夾(jia)(jia)層(ceng)(ceng)(ceng)空(kong)間.中(zhong)(zhong)空(kong)玻(bo)(bo)璃(li)(li)(li)具(ju)有隔音、隔熱(re)、防結霜、防潮、抗(kang)風壓強(qiang)度(du)(du)大等優點(dian).據測量,當室(shi)外溫度(du)(du)為(wei)——10℃時,單層(ceng)(ceng)(ceng)玻(bo)(bo)璃(li)(li)(li)窗(chuang)前(qian)的溫度(du)(du)為(wei)——2℃,而使(shi)用三(san)(san)層(ceng)(ceng)(ceng)中(zhong)(zhong)空(kong)玻(bo)(bo)璃(li)(li)(li)的室(shi)內溫度(du)(du)為(wei)13℃.而在(zai)炎熱(re)夏天,雙層(ceng)(ceng)(ceng)中(zhong)(zhong)空(kong)玻(bo)(bo)璃(li)(li)(li)可(ke)以擋住(zhu)90%的太陽(yang)(yang)輻射熱(re).陽(yang)(yang)光依然可(ke)以透過玻(bo)(bo)璃(li)(li)(li)幕墻(qiang)(qiang),但曬在(zai)身上大多(duo)不會感(gan)到(dao)炎熱(re).使(shi)用中(zhong)(zhong)空(kong)玻(bo)(bo)璃(li)(li)(li)幕墻(qiang)(qiang)的房(fang)間可(ke)以做到(dao)冬暖夏涼,極大地(di)改善(shan)了生活環境.
