超高层施工电梯基础免支撑设计施工

Design and Construction of Super High-rise Construction Elevator Foundation without Support

通过将施工电梯基础设置在新增框架梁、板上,依靠原结构顶板梁、地下室外墙板承受电梯基础及使用时相关荷载。施工电梯基础通过新增框架梁架空在地下室顶板上方,新增框架梁两端依靠地下室外墙墙板和主楼框架结构将受力传递下去,使得地下室顶板免支撑,避免了施工电梯基础范围的地下室后续施工受到影响。

By setting the construction elevator foundation on the newly added frame beam and slab,relying on the original structure roof beam and basement exterior wall slab to bear the elevator foundation and relevant loads in use.The foundation of the construction elevator is overhead above the basement roof by adding frame beams.The two ends of the new frame beams rely on the basement exterior wall panel and the main building frame structure to transfer the stress,making the basement roof free of support,avoiding the influence of the subsequent construction of the basement within the scope of the construction elevator foundation.
