In order to deeply solve the conflict problem caused by the inconsistency between the climbing rhythm of formwork equipment construction and the self-lifting process of tower crane,based on the concept of multi-machine collaboration,on the basis of the independent work of unit steel platform and tower crane,through the integration of various collaborative equipment,the stepped climbing of tower crane is realized.The optimal construction mode is analyzed theoretically by using the established digital dynamic interactive mirror model,and a variety of stair climbing efficient construction modes suitable for tower cranes with different power systems are obtained,which are applied to specific high-rise projects.The engineering application results show that the multi-machine coordinated tower crane stepped climbing efficient construction technology is suitable for different types of super high-rise projects,and is conducive to reducing cost and increasing efficiency of super high-rise projects,enhancing construction safety,and improving the level of intelligent construction.
