[0002] Building is the physical structure that human constructs to meet the needs of living, working, entertainment and so on, covering residential buildings, office buildings, bridges and other types. Reinforcing steel bar is commonly used in construction to enhance the material, mainly made of carbon steel, with high strength and toughness. It is usually embedded in concrete in the form of strips or nets, forming reinforced concrete, significantly improving the tensile and compressive capacity of the structure, ensuring the stability and durability of the building. The use of reinforcing steel bar is an integral part of modern construction, widely used in various infrastructure and high-rise buildings.

[0003] In construction engineering, one end of part of reinforcing steel bar has been cast in concrete, while the other end is exposed outside, in a state of waiting for connection. In order to prevent rusting of reinforcing steel bar, the exposed part needs to be treated for rust prevention. Currently, the common rust prevention method is for workers to carry rust prevention liquid by hand and use a brush to manually apply it to the surface of reinforcing steel bar. This method not only has low efficiency, but also increases the labor intensity of workers. In some cases, due to the remote location of reinforcing steel bar or the long distance from the construction site, the operation difficulty is increased, and even safety hazards may be caused.
