[0002] During construction on site, post-casting strips and construction joints are constructed. The construction time is often very long, which causes the steel bars to be exposed to the air for a long time and slowly rust after being exposed to the wind and sun. Therefore, a layer of rust inhibitor is often applied on the steel bars at the post-casting strips and construction joints to prevent the steel bars from rusting and protect them. This is the background of this invention.
[0003] The traditional construction process of steel bar anti-rust facilities is: the anti-rust agent uses epoxy resin, anti-rust water, anti-rust agent, cement slurry and other materials. Regardless of the type of anti-rust agent, it basically needs to be applied with a brush. Traditional brushing work uses tools such as brown brushes, roller brushes or brooms for construction. During the construction process, it can often only cover the steel bar area in front of the operator. The area where the steel bar is away from the operating surface cannot be painted in place, or the climbing tool is used again to paint the back area for a second time. This makes this process slow, wastes labor, has poor painting quality, and has dead corners for painting.
[0004] During the construction process, the existing painting tools can only cover the steel bar area in front of the operator. The area where the steel bar is away from the operating surface cannot be painted properly, or it is moved to the back area for a second painting. This makes this process slow, wastes labor, has poor painting quality, and has dead corners. Utility Model Content
