Abstract

The invention discloses a prefabricated box girder prestress advanced positioning device, the prefabricated box girder prestress advanced positioning device comprises a corrugated pipe positioning ribwelding positioner, a web stirrup classifying storage support and a bottom web plate steel bar binding positioner, a steel bar positioning pin is arranged on the base steel plate according to the coordinates of the corrugated pipe positioning rib, welding the machined corrugated pipe positioning ribs on the web stirrup, the corrugated pipe positioning ribs are classified and stored on a profile steel support according to the numbers, the bottom web plate steel bar is installed and positioned on the bottom web plate steel bar binding positioner, the corresponding corrugated pipe coordinates can be checked in the installation process, and the installation position of the corrugated pipe locating rib is ensured. When the invention is used, after welding of the corrugated pipe positioning ribis completed, the corrugated pipe positioning ribs are stored in a classified mode on the stirrup storage support according to corresponding serial numbers, the web stirrup is installed on the binding positioner, the operation personnel sequentially install the web stirrup which are welded with the positioning ribs in advance according to the corresponding serial numbers, machining, positioning and installation of steel bars in the whole process form digitalization, modularization and batch production and line production, the installation efficiency, and precision are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of bridge building construction, and in particular relates to a prefabricated box girder prestressed advance positioning device and an implementation method thereof. Background technique [0002] In recent years, with the continuous development of bridge engineering, bridge construction technology has become increasingly mature and diversified. For the prestressed construction of prefabricated box girders, welding positioning ribs on the formed steel skeleton is often used for bellows positioning. The installation speed of this method is slow. , low machining accuracy, can not meet the requirements of mass production. In order to solve the above problems, a prestressed advanced positioning device is invented to improve the installation efficiency and accuracy of the prestressed channel positioning ribs, and to meet the batch processing and production of prefabricated beam fields. Contents of the invention ...
