石材幕墙快挂背栓系统设计与计算OA

This research focuses on the complexity and safety hazards of traditional stone curtain walls,compiles the research and development status of back-bolted-type connected stone curtain walls,designs and strength calculations on back-bolted-type dry-hanging nodes,analyzes the popularization and application advantages of back-bolted-type dry-hanging,and studies the layout of back-bolted-type connection points.Through the shear performance test of back-bolted-type and short-slot type connected stone plates,and the connection performance test of back-bolted-type stone curtain walls panels,the connection mechanical performance of back-bolted-type stone curtain walls was studied.The research results provide a theoretical basis for the design of back-bolted joints and have guiding value for engineering practice.
