[0003] In the related art, the grid shell structure is spherical and is assembled from wooden components. After the grid shell structure is constructed, the curtain wall structure needs to be further installed on the grid shell structure. As the curtain wall structure is installed, the load of the grid shell structure will gradually increase, which may cause displacement and deformation at the joints of the wooden components on the grid shell structure. In severe cases, the grid shell structure may expand and deform outward as a whole, affecting the overall stability of the grid shell structure and the installation and construction of the glass curtain wall. Therefore, there is room for improvement. Summary of the invention

[0018] By adopting the above technical solution, after the adjacent ends of the adjacent cable segments are connected and fixed by the ring cable anchor, the clamping block can be used to release the clamping of the cable segment through the clamping drive component, and at the same time, the lifting drive component is used to drive the cable clamping groove downward until the cable clamping groove is separated from the cable segment, so as to limit the interference of the clamping part with the ring cable when the ring cable is subsequently tensioned.
