[提要] 雙錐面膨脹錨栓（SZM建筑錨栓）是在研究現(xiàn)有各類膨脹錨栓的基礎上，結(jié)合力學試驗結(jié)果和工程應用經(jīng)驗，設計開發(fā)出的高性能錨栓新產(chǎn)品。詳細介紹了這種錨栓的構(gòu)造特征、工作原理、使用方法、性能指標和應用條件，并將其與HILTI（喜利得）和fischer(慧魚)的同類產(chǎn)品進行了比較。
[關鍵詞] 膨脹錨栓 混凝土基材 后連接 后續(xù)膨脹 抗拉拔承載力 抗剪切承載力Based on research about the same kind of expansion anchors which are widely used in construction, combined with the results of necessary mechanical experiments and experiences, a new type of double-cone expansion anchor( SZM expansion anchor)is designed and introduced about the structural characteristic, working principle, using method, performance quota and using condition of the anchor in detail. The bearing capacity of SZM anchor is larger than that of the similar products of famous HILTI and fischer in main targets.
Keywords: expansion; anchor; concrete anchoring base; steel-concrete connection; tension; shear; strength
