The invention discloses a tower crane foundation on an existing structure and a construction method of the tower crane foundation. The construction method on the existing structure comprises the steps that a construction area of the tower crane foundation is measured and positioned above an existing structural plate; a plurality of existing structural columns which are located below the existing structural slab and arranged around the construction area are selected, all the existing structural columns extend upwards, and the top ends of the existing structural columns extend to the position above the existing structural slab to form connecting ends; binding reinforcing steel bars of a bearing platform above the existing structural slab; laying a template of the bearing platform; and concrete is poured into the formwork of the bearing platform, the bearing platform is formed, and the tower crane foundation is jointly formed by the bearing platform, the existing structural plate and the multiple existing structural columns. According to the invention, the load of the tower crane is dispersed on the existing structural plate and the existing structural column, so that the bearing capacity of the existing structural plate is improved, and the tower crane can be directly arranged on the existing structural plate of the existing structure.

    本发明公开了一种既有结构上的塔吊基础及其施工方法,既有结构上的施工方法包括:在所述既有结构板上方测量并定位出所述塔吊基础的施工区域;选取多根位于所述既有结构板下方且环绕所述施工区域设置的既有结构柱,并将各所述既有结构柱向上延伸,使其顶端伸至所述既有结构板的上方形成连接端;在所述既有结构板的上方绑扎承台的钢筋;铺设所述承台的模板;向所述承台的模板内浇筑混凝土,成型出所述承台,以使所述承台、所述既有结构板及多根所述既有结构柱共同形成所述塔吊基础。本发明将塔吊的荷载分散作用在既有结构板和既有结构柱上,提高了既有结构板的承载能力,使得塔吊可以直接设置于既有结构的既有结构板上。
