[0002] With the continued popularity of steel structure construction, the scale of various steel structure construction projects is expanding. Steel columns are typically connected to foundations using pre-buried anchor bolts for secure connection. Accurate anchor positioning is crucial during this process. Misalignment during anchor embedment can also lead to misalignment of the steel columns after installation, compromising the quality of the steel structure. Furthermore, the steel columns may not be properly aligned with the anchor bolts. This requires on-site hole enlargement of the column footings to ensure accurate alignment, impacting the quality of the steel columns.
