AI Technical Summary
Technical Problem
During the lifting and docking process, the steel columns are unstable and easily misaligned, resulting in low docking accuracy.
Method used
The design of combining docking device and limiting device is adopted. Through the combination of connecting seat, threaded interspersed rod and fastening nut, the precise docking of cross steel columns is achieved, and the docking accuracy between the side plates is ensured through the rotating limiting plate and the elastic clamping mechanism.
Benefits of technology
The butt accuracy of steel columns in steel structure is improved, prevents misalignment, ensures accurate interspersion between the connecting seat and the threaded interspersion rod, and improves the overall accuracy of butt installation.

Abstract
The utility model discloses a hoisting butt-joint tool for steel columns of a high-rise steel structure, which comprises cross-shaped steel columns, and butt-joint devices are connected between the adjacent cross-shaped steel columns; a limiting device is connected to the inner side between every two adjacent cross-shaped steel columns, and the butt joint device comprises connecting bases which are installed at the ends between every two adjacent cross-shaped steel columns correspondingly; the threaded insertion rods are vertically inserted between the adjacent connecting seats; and fastening the nut. By means of the arrangement mode that the butt joint device is matched with the limiting device, after the ends of the two cross-shaped steel columns correspond to each other, the rotary limiting plate is rotated, the rotary limiting plate in the horizontal state is rotated to be in the vertical state, and therefore the rotary limiting plate can be transversely arranged between the side plates on the two cross-shaped steel columns; therefore, the butt joint precision between the side plates is guaranteed, dislocation during butt joint of the cross-shaped steel columns is prevented, the insertion precision between the connecting base and the threaded insertion rod is guaranteed, and the butt joint installation precision is higher.
