Deviation analysis and factory correction guiding method of large-scale complicated special-shaped steel component

Abstract

The invention discloses a deviation analysis and factory correction guidance method for large complex special-shaped steel components, which analyzes and corrects the deviation of large complex special-shaped steel components based on comprehensive technologies (computer technology, reverse forming, virtual reality, and three-dimensional scanning technology). Including the following steps: create a steel member Tekla model; make steel members; make a 3D coordinate system for steel member visualization; reversely generate a 3D Test model; convert the Tekla model into a third-party Reference model; make a 3D deviation color difference map; and The deviation part is cut on any surface, and the two-dimensional view deviation analysis diagram is made; the deviation steel member is trimmed. The present invention digests the problems existing in on-site installation in the factory in advance, greatly improves the efficiency of on-site installation, shortens the installation period, and thereby improves the overall progress.

Description

Technical field [0001] The invention belongs to the field of building steel structures, and in particular relates to a method for deviation analysis of large, complex and special-shaped steel components and factory correction guidance. Background technique [0002] In a complex special-shaped steel component manufacturing plant, for the measurement of large and complex special-shaped steel components, traditional steel tapes and total stations have double errors of instruments and labor, and accumulated errors of equipment, resulting in low measurement efficiency and poor measurement accuracy. If there are deviations in the processing, the factory needs to be instructed to correct the deviation, and the deviation data analysis process is complicated. [0003] Due to the measurement error in the production stage of the factory, the measurement error in the on-site installation stage caused the installation error and even failed to install smoothly, which increased the installation ...

AI Technical Summary

Problems solved by technology

[0002] For the measurement of large and complex special-shaped steel components in complex special-shaped steel component manufacturing factories, traditional steel tapes and total stations have double errors of instruments and labor, and equipment accumulation errors, etc., resulting in low measurement efficiency and poor measurement accuracy.

If there is deviation in processing and production, it is necessary to instruct the factory to perform over-bias correction, and the deviation data analysis process is complicated

[0003] Due to the measurement error in the factory production stage, the measurement error in the on-site installation stage will cause installation errors or even fail to install smoothly, resulting in increased installation costs and delays in the installation period
