[0002] As a special arch rib structure form, the hexagonal A-shaped steel arch rib has unique advantages and characteristics in bridge engineering. During the traditional assembly process of the hexagonal A-shaped steel arch rib, after installing the partition plates and stiffening plates on the bottom plate, the installation of the side and upper side wall plates is still required. Before the box-shaped member forms an integral body, due to the inclined angle and the influence of gravity during the positioning of the side wall plates, the phenomena of slipping and displacement are likely to occur, thus affecting the assembly accuracy and efficiency of the members. Especially for the assembly of the side wall plates contained in the curved section of the steel arch rib, the difficulty is greater. Using the traditional method relying only on manual assistance for positioning, it is necessary to continuously move and position by manpower during the installation and positioning process, wasting manpower and having an inaccurate placement position. During the welding process, the phenomenon of component movement is likely to occur. Summary of the Invention
