Loop cable node connecting device for CFRP cable suspended dome structure

The utility model provides an endless cable node connecting device for a CFRP cable suspended dome structure. The endless cable node connecting device comprises a CFRP cable anchoring part and a universal transmission node, and the anchoring parts of the adjacent CFRP cables are connected through universal transmission nodes. The CFRP cable anchoring part comprises a CFRP ring cable, a first end,an anchoring sleeve and a second end; a 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. And the CFRP ring cable is anchored in the anchoring sleeve. According to the utility model, the adjacent subsections of CFRP ring cables are effectively connected together, so that smooth connection of the connecting node and the CFRP ring cable curve is realized, bending internal force generated during connection is avoided, and the defect of poor shear capacity of the CFRP ring ca
