[0002] In the field of modern architecture, special-shaped reticulated shell steel structures are widely used due to their unique spatial shapes and mechanical properties. However, there are significant technical bottlenecks in the traditional assembly process. Existing methods rely on manual measurement and positioning, which are not only inefficient but also difficult to guarantee accuracy. Especially in the assembly of complex curved surface structures, component size deviations and spatial position errors can lead to instability of the overall structure.

[0003] Traditional jigs are mostly in fixed forms and are difficult to adapt to the complex contours of special-shaped components, resulting in insecure clamping or local stress concentration, affecting construction quality and safety. Moreover, when dealing with components with different curvature radii, it is necessary to frequently replace the jig models, resulting in reduced processing efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent assembly positioning device for special-shaped reticulated shell steel structures and its construction method. By setting a special-shaped clamping mechanism, the three-level arc disk nested structure can automatically fit the complex curved surface of the component through the flexible cooperation of the limit card slot and the sliding block, realizing all-round wrapping and clamping, effectively dispersing stress and avoiding local deformation, improving clamping safety. The modular clamping components can quickly adapt to components with different curvature radii, reducing the frequency of jig replacement, so as to solve the problems raised in the above background art.
