The invention discloses an external tower crane alternate conversion attachment system and a construction method. A tower crane structure comprises a tower crane, a temporary attachment system and a formal attachment system; the temporary attachment system and the formal attachment system are both arranged on the tower crane; the formal attachment system is located below the temporary attachment system; the two ends of the temporary attachment system are connected to the tower crane and a core tube correspondingly; and the two ends of the formal attachment system are connected to the tower crane and an outer frame column correspondingly. For a super high-rise building constructed by adopting a core tube first-moving and outer frame following method, when the height difference between the working surfaces of the core tube and the outer frame is too large, a temporary attachment system is adopted firstly, so that the phenomenon that the tower crane cannot be effectively attached to cause idleness of the tower crane due to the too large height difference between the working surfaces; and when the outer frame column is constructed above the temporary attachment position, temporary attachment is converted into formal attachment, so that the influence of a tower crane attachment rod piece on subsequent decoration and curtain wall construction of a building is avoided, and the overall construction progress of a project is facilitated.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to an alternate conversion attachment system of an external tower crane and a construction method. Background technique [0002] Super high-rise building construction has a lot of intersections among different disciplines, material hoisting height is high, and vertical transportation and construction organization are difficult. In the super high-rise vertical transportation construction, the tower crane, as the main heavy component and material hoisting machine, its plane layout and quantity will play an important role in the smooth progress of the entire project construction. Externally attached tower cranes are widely used in the vertical transportation construction of super high-rise buildings because of their convenient installation and disassembly and their ability to cover a large area of construction materials. [0003] The attached tower is set on the outsid...
