[0002] The steel structure in building construction is a common structural form, which is usually composed of steel and is used to support the weight of the building and provide structural stability. The application of steel structures in buildings is very extensive, and its advantages include high strength, good durability, fast construction speed, strong plasticity, etc., so it is widely used in various building types, such as commercial buildings, industrial factories, bridges, stadiums, etc. The steel structure is easily affected by oxidation and corrosion when exposed to the air, especially in humid or rainy environments. By spraying a suitable anti-corrosion paint, a protective layer can be formed to effectively isolate air and moisture, prevent the corrosion of the steel structure surface, and extend its service life.

[0003] Traditional steel structure surface painting devices usually include spraying guns, spraying pumps, compressed air systems, etc. The spraying gun sprays the paint onto the steel structure surface through compressed air, and the spraying pump is responsible for transporting the paint from the liquid storage container to the spraying gun. Usually, manual operation is required to ensure the painting quality and operation safety.

Especially for a large number of steel pipe painting tasks, more manpower and time are required. Therefore, a steel structure surface painting device for building construction is proposed to solve the above problems. Content of the Utility Model
