PULL-OUT EXPERIMENTAL STUDY ON NEW TYPE OF CHEMICAL ANCHORING BOLTS
-
摘要: 介绍一种新型化学锚栓。该化学锚栓的锚固剂由无机化学材料组成，具有优越的耐高温性能。通过在C30混凝土中进行M12新型化学锚栓的拉拔试验，对不同锚固长度下的破坏形态进行分析，得出M12新型化学锚栓在C30混凝土中的有效锚固长度，进一步得出M12新型化学锚栓的设计承载力，为新型化学锚栓的工程应用设计提供依据。Abstract: It is introduced a new type of chemical anchoring bolt,and the anchoring agent of the chemical anchoring bolt is composed of inorganic chemistry material,and it has good resistance to elevated temperatures.According to the pull-out test of the M12 new type of chemical anchoring bolts in C30 concrete,the failure mode in different anchorage length is analyzed and the effective anchorage length in C30 concrete is obtained and further the design capacity is also got,the result provides a basis for its engineering application design.
