Experimental Research on Shear Performance of Stainless Steel Connectors in a New Type of Prefabricated Concrete Sandwich Insulation Wall Panels
Based on reducing the energy consumption of buildings and achieving the purpose of energy conservation and emission reduction,a set of stainless steel connectors suitable for a new type of precast concrete sandwich insulation wall panels was developed,which can realize the integrated prefabrication of external stone decoration and wall insulation.The shear performance tests of two stainless steel connectors were systematically carried out,and the results showed that the shear failure mode of the stone connection interface was brittle failure,the stone was separated from the concrete and the connector,the end of the connector was bent,and the vertical arrangement of fish-type connectors had a greater impact on the shear resistance of the connection interface than the horizontal arrangement,and the average measured shear bearing capacity was 22.2%greater.The shear failure mode of plate connectors was concrete cracking,the connector and anchor steel rebars deformed.In the specimens arranged with two or four plate connectors,the test values of shear bearing capacity of a single connector was 29.75 kN and 26.35 kN,respectively.Through theoretical calculation and comparative analysis of test data,it was found that the shear resistance of the two types of connectors were good,and both had large safety reserves.
