Description

Technical Field

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

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete, which is widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures. However, during house construction, the steel bars used for construction are piled up for a long time. The steel bars are easily rusted during transportation due to the friction between the steel bars, causing the anti-rust layer on the surface of the steel bars to fall off. When a large amount of rust occurs on the surface of the steel bars, it will affect the adhesion between the steel bars and the concrete. Therefore, the steel bars need to be derusted before use. However, the derusting of the steel bars needs to be considered in relation to the diameter of the steel bars. It is not very convenient to derust steel bars of various specifications during construction. Utility Model Content
