Abstract

The application relates to the field of fabricated foundation construction, in particular to a positioning device for installing a stand column on a cup mouth foundation and a construction method. The positioning device for installing the stand column on the cup mouth foundation comprises a positioning frame and a hoop. The positioning frame is provided with a first positioning surface and a second positioning surface, the first positioning surface and the second positioning surface are perpendicular to each other, the first positioning surface and the second positioning surface are used for respectively abutting with adjacent two side surfaces of a stand column to be installed, and the positioning frame can be fixed on the top surface of the cup mouth foundation; a supporting table is arranged on the positioning frame; the hoop is used for being installed on the stand column to be installed, the hoop is provided with a positioning plate, and the positioning plate can be supported on the supporting table. The application can quickly realize the horizontal positioning of the stand column to be installed, the installation operation of the design elevation determination and the perpendicularity adjustment, and further improves the construction efficiency in the process of installing the stand column to be installed on the cup mouth foundation, and significantly shortens the overall construction period.
