Abstract

A method for digitally simulate pre-assembling construction of steel structure bridge includes detecting segment pre-assembly of steel structure beam segment and digital-analog pre-assembly of bridge,The method comprises the following steps: step a1: establishing an overall model of a steel structure bridge according to design data; step a2: extracting a segmented model and establishing a coordinate system; step a3: determining a control point of the segmented size and a coordinate value of the control point in the model, which relates to the technical field of construction. A digital analogpre-assembling construction method for steel structure bridges so that the total station can be used for measuring by simulating pre-assembling, the control points in the solid assembly are detected during the detection of a single component, including all the control points between adjacent components. The computer is used to process the data, and the coordinate value comparison and three-dimensional model fitting of the pre-assembled components are carried out at the same time.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a digital simulation pre-assembly construction method for a steel structure bridge. Background technique [0002] Due to the limitation of transportation or hoisting conditions, large steel structure bridges are generally fabricated and installed in sections. In order to test the integrity and accuracy of bridge fabrication and ensure the smooth implementation of on-site installation, the sectioned bridge body needs to be carried out before leaving the factory. Pre-assembled in the factory. The structural form of steel structure bridges is relatively complex, and there is a spatial correlation between components, which requires high manufacturing accuracy of the interface between components. Due to the influence of cumulative errors, sometimes it is impossible to meet the requirements of on-site installation only by controlling the manufacturing accuracy of individual compon...
