Construction method of large-size elastic sliding plate support structure arranged on column

The invention discloses a construction method of a large-size elastic sliding plate support structure arranged on a column, which overcomes the defects that the height of a lower buttress is insufficient and the size of a lower supporting column is insufficient for supporting the lower buttress by improving the pre-embedded arrangement of a lower pre-embedded anchor bar assembly, and ensures the structural stability of the elastic sliding plate support structure. The shock insulation requirement of a building is guaranteed, the pouring quality of the lower buttress is guaranteed in a secondary grouting and secondary vibrating mode, and then the safety and stability of the shock insulation support are guaranteed; the damaged sliding face is replaced by jacking the upper buttress and adopting a translation dragging mode, the convenience of the sliding face replacement process is guaranteed, meanwhile, it is guaranteed that the sliding face is free of damage in the sliding face replacement process, the method ha
