Mounting construction technology of steel structure steel column

The invention discloses a mounting construction technology of a steel structure steel column. The technology comprises steps as follows: the elevation of the bracket surface of the steel column is measured, the elevation of the column foot and a foundation support surface is determined, and the support surface is adjusted; a foundation bolt is embedded; a truck crane hangs the top end of the steel column, the top end of the steel column rises and rotates until the steel column is in the vertical state, lifting is stopped, the truck crane moves downwards, and the bottom of the steel column aligns to the foundation bolt; after the steel column is hung by the truck crane in place, a bottom plate of the steel column penetrates through the foundation bolt to be placed on a nut, the column foot is adjusted, center lines of four sides of the steel column align to a base reticle, the perpendicularity of the body of the steel column is measured by an instrument, and the bolt is tightened and welding fixation is performed after the steel column is corrected. The mounting construction technology of the steel structure steel column has reasonable steps and is simple to operate, high in mounting speed, high in mounting accuracy and safe and reliable in project quality.
