Operating platform for pre-embedding construction of steel structure group column bolts

The utility model provides an operation platform for pre-embedding construction of bolts of a steel structure group column, which is characterized in that in coaxial group columns, one operation platform is arranged at the top of each column; in the operation platform, four vertical steel bars are vertically welded to main steel bars at the four corners of the column respectively, a horizontally-arranged horizontal steel bar is welded to the position, corresponding to the preset installation height of the positioning plate, between every two adjacent vertical steel bars, and corresponding axis points corresponding to the axis of the group column are marked on the horizontal steel bars with the axis pile as the benchmark; a plurality of horizontally arranged reinforcing steel bars are welded between one pair of parallel horizontal steel bars at intervals, and axis points on the horizontal steel bars are aligned with positioning axes at corresponding positions on the positioning plate one by one to position the
