[0002] Construction projects refer to engineering entities formed through the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines and equipment. Steel bars refer to steel materials for reinforced concrete and prestressed reinforced concrete. Their cross-sections are circular, and sometimes square with rounded corners. They are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures.
[0003] When conducting steel bar quality inspection in construction projects, the steel bars are bent during inspection in order to measure the tensile strength, yield strength, elongation and other indicators of the steel bars. When in use, traditional steel bar bending devices can only bend in an arc and cannot directly perform circle bending. As a result, the inspection range of the steel bars is limited and the scope of application is narrow. Some bending devices require repeated adjustments before continuous bending, which reduces the practicality of the bending device. Summary of the invention
