Synchronous construction method for steel structure frame and reinforced concrete core tube

The invention relates to the technical field of steel structure building engineering construction, in particular to a synchronous construction method for a steel structure frame and a reinforced concrete core tube. By adjusting the construction sequence, the steel frame columns and the steel frame beams except for the connecting span part in the mixed structure are independently constructed, and construction of components at the connecting span part is delayed, so that the situation that the overall progress of a steel structure frame is lagged due to the fact that core tube concrete does not reach the design strength, and an outer frame occupies the operation space is avoided. According to the construction method, the overall construction period of a project can be effectively shortened, the construction progress of the steel structure frame part is accelerated, a favorable environment is created for subsequent secondary structure and decoration project construction, and the construction method is particular
