Problems solved by technology

[0004] When using ordinary prisms for deformation monitoring, due to the difficulty in placing the prisms at the deformation monitoring point, it is necessary to pre-weld the prism installation base on the steel components before splicing and positioning the steel components, which will cause structural damage to the steel components. Destroy the shape of the steel member
When using a special target patch to measure the accuracy, the measurement accuracy will be reduced by 50%, and the special target patch cannot be used on round steel members
At the same time, the structural forms of complex steel structure projects are diverse, and the measurement angles are changeable. Ordinary prisms cannot meet the requirements of angle transformation.

Description

technical field [0001] The invention relates to the technical field of deformation measurement and positioning of steel components, in particular to a monitoring device and a monitoring method for deformation points of steel components. Background technique [0002] Due to its short construction period, small structural section, light weight and good seismic performance, steel structure engineering has developed rapidly in my country. This makes the monitoring of steel structure deformation more and more important, which directly affects the safety of the building itself and the safety of people's lives and properties. [0003] At present, domestic steel structure building deformation monitoring methods often use: precision triangulation method, distance or angle intersection method, total station polar coordinate method and GPS method, etc. In the deformation monitoring of large-span complex steel structure engineering, the polar coordinate measurement of total station com...
