Description

Technical Field

[0001] The utility model relates to the technical field of steel bar rust removal, in particular to a steel bar rust removal device. Background Art

[0002] During the construction of a building project, the steel bars stored at the construction site will inevitably rust due to long-term contact with the atmosphere. Steel bar corrosion will reduce the bonding strength between the steel bars and concrete, so that the tensile force on the steel bars cannot be effectively transferred to the concrete. At the same time, the corrosion products generated by the rust will accumulate between the concrete and the steel bars. The volume expansion and compression will cause the concrete protective layer to crack, bulge, and peel off, causing the bonding strength between the steel bars and the concrete interface to decrease rapidly.

[0003] At present, the rust removal of steel bars at construction sites is mainly done manually, that is, workers use wire brushes to repeatedly brush the surface of each steel bar. Manual rust removal is labor-intensive, inefficient, and requires a lot of manpower and time. In addition, the rust removal effect is not ideal and it is difficult to remove it completely. Steel bars that have not been completely rusted will still leave hidden dangers when used in concrete structures.

[0004] Therefore, it is necessary to propose a device for removing rust from steel bars to solve the above problems. Utility Model Content
