The invention provides a construction method for changing the length of a cargo boom in the air of a tower crane and a supporting structure. The construction method comprises the following steps that S10, a supporting platform is erected on the current roof of a constructed tower; and S20, the cargo boom of the tower crane to be modified is moved to the supporting platform, and the length of the cargo boom is changed on the supporting platform. According to the technical scheme, the roof of the constructed tower building is used as the foundation, the supporting platform is erected on the top of the tower building, and the length of the cargo boom of the tower crane is changed through the supporting platform, so that the tower crane does not need to descend to the ground, secondary mounting and dismounting of standard knots and wall attaching rods are avoided, a large amount of construction period can be saved, and construction efficiency is improved. And the tower building can be continuously constructed on the premise of ensuring advanced operation of the podium building. In addition, the complicated process of descending dismantling and re-installation jacking is omitted, and the technical problem that the attachment rod cannot be installed in the later period due to deformation is solved due to the fact that the construction period is shortened.
本发明提供了一种塔吊空中变换起重臂长度的施工方法及支撑结构，所述施工方法包括以下步骤：S10：在所施工的塔楼当前的楼顶搭设支撑平台；S20：将待改装的塔吊的起重臂移动至所述支撑平台上，在所述支撑平台上对所述起重臂进行变换长度的操作。应用本发明的技术方案，通过利用所施工的塔楼的楼顶作为基础，在其顶部搭设支撑平台，通过支撑平台对塔吊的起重臂进行变换长度的操作，使塔吊无需下降至地面，免除二次安拆标准节以及附墙杆，可节省大量工期，可以在保证裙楼提前营业的前提下塔楼继续施工。另外，免去了下降拆除与重新安装顶升的繁杂过程，而且，由于工期缩短，也避免了附着杆变形后期无法安装的技术难题。
