AI Technical Summary

Technical Problem

The construction and painting of the integrated steel structure with suspended beams presents challenges such as high construction difficulty, low safety, poor construction reliability, and low painting efficiency. In particular, the flipping and hoisting operation is cumbersome and increases the workload of the workers.

Method used

An integrated steel structure for suspended beams and its prefabrication device were designed. Through a combination of a fixed mechanism, an intermittent mechanism, a ratchet and a pawl rack, and a reciprocating screw drives the moving frame to move the pawl rack and the painting mechanism, so as to realize the automatic flipping and painting of the suspended beams and reduce manual flipping operations.

Benefits of technology

The system enables automatic flipping and painting of suspended beams, reducing the workload of workers, improving painting efficiency, simplifying the construction process, and reducing construction risks.
