Large-span overhanging scaffold foundation free of back-jacking and construction method of large-span overhanging scaffold foundation
The invention relates to the technical field of suspension scaffold supporting, in particular to a back-jacking-free large-span cantilever scaffold foundation and a construction method thereof.The back-jacking-free large-span cantilever scaffold foundation comprises a cantilever structural plate, the cantilever structural plate is poured on the outer side of a building stand column, and a connecting structural plate is arranged at the connecting position of the cantilever structural plate and the building stand column; the reinforcing reinforcement cage is fixed to one end of the built-in I-shaped steel and located on the edge of the cantilever structural slab. One end of the scaffold overhanging I-shaped steel extends to the outer side of the overhanging structural plate; the building stand column has the beneficial effects that the built-in I-shaped steel and the reinforcing cross beam are arranged in the cantilever structural plate in advance, and the scaffold cantilever I-shaped steel arranged on the upper surface of the cantilever structural plate is fixed to the reinforcing cross beam and the reinforcing reinforcement cage through the two positioning assemblies correspondingly, so that the building stand column can share the supporting force of the cantilever structural plate; therefore, deformation and damage of the cantilever structural plate can be avoided without arranging a back-jacking support, the erecting cost of the scaffold is reduced, and meanwhile the construction period is shortened.
本发明涉及悬吊脚手架支撑技术领域，具体为一种免回顶大跨度悬挑脚手架基础及其施工方法，包括：悬挑结构板，悬挑结构板浇筑于建筑立柱的外侧，悬挑结构板与建筑立柱的连接处设置有连接结构板；加固钢筋笼固定于内置工字钢的一端并位于悬挑结构板的边缘；脚手架悬挑工字钢的一端伸出至悬挑结构板的外侧；有益效果为：通过在悬挑结构板的内部预设置内置工字钢和加固横梁，悬挑结构板上表面设置的脚手架悬挑工字钢通过两个定位组件分别与加固横梁和加固钢筋笼进行固定，使得建筑立柱能够分担悬挑结构板的支撑力，进而无需设置回顶支撑也能够避免悬挑结构板发生变形损坏，降低了脚手架的支设成本，同时缩短施工周期。
