The invention discloses a narrow core tube internal climbing type tower crane high turnover reinforcing method, and particularly relates to the technical field of building construction, the specific reinforcing steps are as follows: S1, tower crane climbing planning: determining and designing the number of climbing times of a tower crane according to the to-be-built height of a high-rise building and the height of an internal climbing type tower crane; s2, tower crane reinforcement adopts a working mode that shear walls and peripheral frame beams are cooperatively stressed; s2.1, tower crane reinforcement of the B1 layer: one end of a tower crane tool beam is connected with a shear wall of the building, and the other end of the tower crane tool beam is arranged on a peripheral frame beam; and S2.2, tower cranes from the B2 layer to the Bn layer are reinforced. The tower crane arrangement mode that the core tube shear wall and the peripheral structural beams are cooperatively stressed is provided, and based on the arrangement mode, it is found that an existing structure cannot bear tower crane loads and needs to be reinforced, so that the construction efficiency and economic benefits are comprehensively considered, and the construction cost is lowered. The reinforcing method that only one side of the shear wall needs to be reinforced, the structure on one side of the frame beam does not need to be reinforced, and high turnover of components is achieved is provided, and high operability and economical efficiency are achieved.
本发明公开了狭窄核心筒内爬式塔吊高周转加固方法,具体涉及建筑施工技术领域,具体加固步骤如下所示:S1、塔吊爬升规划:按照高层建筑的待建高度及内爬式塔吊高度确认设计塔吊爬升次数;S2、塔吊加固采用剪力墙与周边框架梁协同受力的工作方式;S2.1、B1层塔吊加固:将塔吊工具梁的一端与建筑的剪力墙相连,另一端置于周边框架梁上;S2.2、B2至Bn层塔吊加固。本发明通过提出了核心筒剪力墙与周边结构梁协同受力的塔吊布置方式,基于该布置方式,发现既有结构无法承受塔吊荷载,需要予以加固,因此,综合考虑施工工效和经济效益,提出了“仅需在剪力墙一侧加固而框架梁一侧结构免加固、构件高周转”的加固方法,具有很强的可操作性和经济性。
