AI Technical Summary

Technical Problem

Existing steel profiles are prone to bending and deformation during manufacturing, transportation, and installation, resulting in poor construction quality. Furthermore, straightening requires returning the steel to the processing plant, increasing costs and reducing efficiency.

Method used

Design a steel profile straightening device, including a carbon steel base, a placement groove, a pressing component and a straightening cylinder, combined with a reinforcing rib structure of annular, vertical and inclined ribs, and using non-metallic pads to reduce wear and increase rigidity.

Benefits of technology

This technology enables on-site straightening of steel profiles, reduces base wear and self-weight, improves operational convenience and straightening efficiency, and ensures construction quality.
