Spatial grid structure and grid enclosure structure are esthetic,reliable,safe and economic,so they have been well accepted.With comprehensive application and fast development,accident of grid structure often happens.After analysis on reasons causing accidents of grid structure,different measures,such as overall reconstruction,local reinforcement,reinforcement by node and reinforcement by support,etc.,are usually adopted respectively according to different damage degrees.A kind of displacing device for reinforcement of grid structure rod is successfully designed with references to existing documents and sufficient studies have been carried out on such device.%空间网架及网壳结构具有的美观性、可靠性、安全性和经济性已被世人所公认.在广泛应用和迅猛发展的同时,网架结构事故也时有发生.通过对网架结构事故的原因分析,对损坏程度不同的网架,通常分别采取拆除重建、局部加固、节点加固、托件加固等不同措施来处理.结合现有文献资料,设计出一种针对网架结构杆件加固的置换装置,并对此进行了分析研究.
