Method for achieving steel structure pre-assembling through computer simulation

Abstract

The invention relates to a method for achieving steel structure pre-assembling through computer simulation. The method includes the following steps: (1) obtaining assembled components according to a steel structure detail drawing model, and automatically compiling component splicing numbers, (2) extracting feature information of the assembled components in the detail drawing model, calculating actual coordinates of the assembled components according to extracted features, generating theoretical measurement and control point three-dimensional coordinates of the components, and automatically naming the numbers, (3) according to the theoretical measurement and control point numbers, positioning and marking the solid components, (4) conducting three-dimensional coordinate measurement on positioning marks through a three-dimensional coordinate measuring instrument, and obtaining actual measurement three-dimensional coordinates of positioning points, and (5) conducting contrastive analysis on theoretical coordinates and the actual measurement coordinates of control points, and providing a rectification report or a pre-assembling examining report according to national steel structure manufacturing technical regulations and technological requirements, the rectification report or the pre-assembling examining report serves as an evidence of the quality control link. The method has the advantages that the theoretical control points are intelligently and automatically generated, errors caused by manually drawing up the theoretical control points can be greatly reduced, and the machining and production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of steel structure pre-assembly, in particular to a computer simulation method for steel structure pre-assembly. Background technique [0002] At present, in the field of steel structure pre-assembly, the method of using computer to simulate pre-assembly is still a semi-manual method. The current two methods cannot be promoted on a large scale, and their disadvantages are: [0003] (1) Adopt the method based on laser scanning. Forming the physical component into a grating (point cloud model), converting the grating into a solid model on the computer, and then comparing it with the model in the computer, the manual workload is huge, the efficiency is low, and the manual error is large. (2) Use the method of manually specifying the measurement and control points. Manually designate the control points in the computer, and then compare them with the actual measurement. The manual workload is also very large, ...

Problems solved by technology

Manually designate the control points in the computer, and then compare them with the actual measurement. The manual workload is also very large, resulting in many missing points and wrong markings, which directly leads to production backlogs and low efficiency.
