[摘要]玻璃為脆性材料,其側(cè)面許用應力小于大面許用應力,約為大面許用應力的70%。大尺寸全玻璃幕墻通常采用吊掛玻璃結(jié)構(gòu),避免下端支承玻璃幕墻的側(cè)面擠壓受力方式,而是通過玻璃上方的吊夾構(gòu)件對其的擠壓夾緊,將玻璃吊掛在主體結(jié)構(gòu)上,玻璃的下方懸空不承受擠壓,玻璃承受吊夾的擠壓力和重力;因承受風壓,玻璃需作四邊支撐處理,受力都是通過其大面接觸面承受大面擠壓力。但是當玻璃幕墻上方結(jié)構(gòu)受限無法采用吊掛結(jié)構(gòu),以及當尺寸大到需要兩塊玻璃拼接而下方玻璃不宜采用吊掛結(jié)構(gòu),下端吊掛(反吊掛)玻璃結(jié)構(gòu)就是最佳選擇之一。因其強度、剛度計算與其他結(jié)構(gòu)的相同,只分析下端吊掛玻璃結(jié)構(gòu)在重力作用下的強度計算,舉例分析說明下端吊掛玻璃結(jié)構(gòu)的應用可靠易行。

Abstract: Glass is brittle material, its lateral allowable stress is less than the bedding face allowable stress, about 70% of the bedding face allowable stress. Large size full glass curtain wall usually adopts hanging glass structure, avoid the side of the bottom bearing glass curtain wall extrusion stress modes, but through the glass at the top of the suspension clamp component of the extrusion clamp, glass hanging in the main structure, the bottom of the glass dangling not bear extrusion, glass clamps under the extrusion pressure and gravity. Due to withstand wind pressure, the glass needs to make four edges supported processing, stress is through its bedding face contact bedding face under extrusion.But when the glass curtain wall structure limited cannot use hanging above the structure, and when the large size glass need two pieces of glass mosaics, the below galss should not be hanged, bottom hanging (reverse hanging) glass structure is one of the best choice. Because of its strength, it only analyzes the bottom hanging glass structure under the action of gravity is strong, for example analysis is given to illustrate the application of the bottom hanging glass structure is reliable and feasible.
Keywords: bottom hanging glass structure; full glass curtain wall; hanging glass structure
