Abstract

The invention provides a horizontal positioning device for a prefabricated stand column. The horizontal positioning device comprises a positioning frame (1), wherein the positioning frame (1) is defined by side walls on the periphery, and the center of the positioning frame (1) is of a hollow frame-shaped structure. The lower portion of the positioning frame (1) is connected to a horizontal position, where the prefabricated stand column needs to be positioned, of a bearing platform in a positioned mode. The shape of the inner edge of the positioning frame (1) is identical or approximately identical to the shape of the cross section of the prefabricated stand column. The area defined by the inner edge is identical or slightly larger than the cross sectional area of the prefabricated stand column. According to a steel bar jig frame manufactured through the horizontal positioning device, and precise positioning and positioning correction of the prefabricated stand column in the horizontal direction can be effectively achieved, so that when the prefabricated stand column and the bottom bearing platform are spliced, the positioning precision of the horizontal position of the prefabricated stand column is high, and control operation is easy and convenient. The invention further relates to a positioning and installing method of the horizontal position of the prefabricated stand column through the horizontal positioning device for the prefabricated stand column.

Description

technical field [0001] The invention belongs to the field of bridge substructure construction, and in particular relates to a horizontal positioning device for a prefabricated column in a bridge prefabricated assembly construction process and a method for positioning and installing the prefabricated column. Background technique [0002] With the promotion and popularization of prefabricated assembly construction technology in domestic urban bridge construction, the steel sleeve grouting connection technology has gradually been applied in the vertical connection of prefabricated concrete components such as prefabricated columns and prefabricated cover beams. However, the prefabricated columns using sleeve grouting technology have not been widely used in practice due to their complexity and high precision requirements. [0003] In the prefabricated assembly process of traditional building construction, the method of axis positioning can be used to control the splicing and posi...
