The invention discloses a tower crane standard section structure in an upper introduction mode. An introduction beam (2) is provided with an introduction bolt hole and connected with a transition steel plate block (4), and a steel channel block (3) is connected with the lower end of the transition steel plate block (4) and located under the introduction bolt hole. The structure can meet the requirement for introducing addition-subtraction sections in a pre-tightening mode with a suspender matched with a bolt and the requirement for introducing the addition-subtraction sections in a mode that an introduction chainlet is matched with a positioning block; classified management expense brought by the two different standard sections is saved, the applicability of the standard section to different introduction modes of upper introduction is improved, and the application range of the standard section is enlarged.
