External tower crane alternate conversion attachment system and construction method
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.
本发明公开了一种外附塔吊交替转换附着体系及施工方法，塔吊结构包括塔吊、临时附着体系和正式附着体系，所述临时附着体系和正式附着体系均设置在塔吊上，所述正式附着体系位于临时附着体系的下方，所述临时附着体系的两端分别连接在塔吊和核心筒上，所述正式附着体系的两端分别连接在塔吊和外框柱上。对于采用“核心筒先行，外框跟随”方法施工的超高层建筑，在核心筒和外框作业面高差过大时，先采用临时附着体系，避免了塔吊因作业面高差过大而无法有效附着，出现塔吊窝工的现象；当外框柱施工至临时附着位置以上时，将临时附着转换成正式附着，避免了塔吊附着杆件对建筑后续装修、幕墙施工的影响，有利于工程总体的施工进度。
