Ring cable node connecting device for CFRP cable string support dome structure

The invention provides a ring cable joint connecting device for a CFRP cable string support dome structure. The ring cable joint connecting device comprises CFRP cable anchoring parts and universal transmission joints; the adjacent CFRP cable anchoring parts are connected through universal transmission joints. Each CFRP cable anchoring part comprises a CFRP ring cable, a first end, an anchoring sleeve and a second end; the first end and a second end are installed at the two ends of the anchoring sleeve respectively, and the anchoring sleeve is connected with the universal transmission joint through a connecting piece. The CFRP ring cable is anchored in the anchoring sleeve. Adjacent segmented CFRP ring cables are effectively connected together, smooth connection of connecting nodes and CFRP ring cable curves is achieved, bending internal force generated in the connecting process is avoided, and the defect of poor CFRP cable in shear capacity is overcome. 本发明提供了一种用于CFRP索弦支穹顶结构的环索节点连接装置，包括CFRP索锚固部分和万向传动节点；相邻的所述
