Problems solved by technology

[0005] When the traditional measurement method is used to correct the plane position and verticality of the prefabricated column, the on-site operation is more complicated
However, the volume and mass of the column are relatively large, and it is time-consuming and labor-intensive to repeatedly adjust the plane position and verticality of the column, and there are certain safety risks.

Abstract

The invention belongs to the technical field of prefabricated bridge construction, and discloses a measuring and positioning device. The key points of the technical scheme include four sets of labels arranged on the side of the column, a longitudinal measuring instrument and a transverse measuring instrument erected on the bearing platform. A measurement and positioning method for the installation of bridge prefabricated columns, the key points of the technical solution include setting out the axis of the column and pasting labels, erecting a longitudinal measuring instrument, erecting a horizontal measuring instrument and a cylinder, adjusting the posture of the column according to the longitudinal monocular telescope, and using a support frame Limiting the position of the column and adjusting the posture of the column according to the horizontal monocular telescope can accurately measure and position the column, quickly correct the plane position and verticality of the column, and achieve high control accuracy.

Description

technical field [0001] The invention relates to the technical field of prefabricated bridge construction, in particular to a measuring and positioning device and a measuring and positioning method for installing bridge prefabricated columns. Background technique [0002] In the process of urban bridge construction, in order to achieve rapid construction and shorten the construction period, construction parties are increasingly using prefabricated columns and prefabricated box girders as the core prefabricated construction technology. [0003] The Chinese patent with the notification number CN105421222B discloses a bridge prefabricated pier column and cap socket connection structure and its assembly method. The structure includes a column and a cap, and the column includes an exposed end and an embedded end. The column installation hole, the cross-sectional shape and size of the column installation hole match the cross-sectional shape and size of the embedded end so that the ...
