Super high-rise steel structure cantilever conversion construction method
The invention belongs to the technical field of super high-rise steel structure building construction, and particularly relates to a super high-rise steel structure cantilever conversion construction method. In order to solve the problems that the weight of a component at a cantilever conversion part is large, the requirement for component installation precision is high, high-altitude hoisting and cross operation are much in the installation process, and the construction period is tight, a cantilever conversion system is divided into a conversion inclined column, an inner side box type beam and an outer side box type beam, and a temporary support is arranged below the conversion incline column; the conversion incline column, the outer side box type beam and the inner side box type beam are hoisted to designated positions and temporarily fixed after being subjected to primary correction, retesting and correction are conducted again after the cantilever conversion system is integrally hoisted, and the splicing position is welded after correction is completed. According to the super high-rise steel structure cantilever conversion construction method, the cantilever conversion system is divided into the conversion inclined column and the box type beams on the inner side and the outer side, so that the mechanical cost and the transportation cost are reduced, and the construction difficulty is reduced.
本发明属于超高层钢结构建筑施工技术领域，具体涉及一种超高层钢结构悬挑转换施工方法；为了解决悬挑转换部位构件重量大，构件安装精度要求高，安装过程高空吊装、交叉作业多、施工工期紧的问题，将悬挑转换体系分割为转换斜柱与内、外侧箱型梁，在转换斜柱下设置临时支撑，转换斜柱、外侧箱型梁、内侧箱型梁吊入指定位置经初次校正后临时固定，悬挑转换体系整体吊装完成后，复测、再次校正，校正完成后焊接拼接处。本发明提供的一种超高层钢结构悬挑转换施工方法，将悬挑转换体系分为转换斜柱与内外两侧箱型梁，不仅降低了机械成本、运输成本，而且减少了施工难度。
