Description

Technical Field

[0001] The present invention belongs to the technical field of steel structure spraying systems and spraying methods, and in particular relates to a steel structure spraying system and a method for spraying steel structures using the system. Background Art

[0002] With the increase in steel structure buildings, the use of steel components has also increased accordingly. The current production process of steel components first involves welding. In order to increase the corrosion resistance of steel components, it is necessary to spray anti-corrosion paint on the surface of the welded steel components. Due to the large size and heavy weight of steel components, the current method of spraying anti-corrosion paint on steel components is mainly the following: the steel component is lifted by a lifting mechanism, a pad is set underneath, and the steel component is placed on the pad. The surface of the steel component is then sprayed with a spray gun. After spraying, it is dried or baked, and then the sprayed steel component is lifted away by the lifting mechanism. The above method has the following defects: First, it takes up a large space. In order to improve production efficiency, multiple steel structures are arranged together for spraying, which requires a larger space for construction; second, due to the large space, the spray mist generated during the spraying process cannot be collected, causing air pollution; third, the contact area between the pad and the steel structure is large, and the area of ​​the bottom surface of the steel structure that is not sprayed is large, which makes subsequent processing difficult; fourth, the pad and the steel structure are not firmly fixed, and the steel structure is easy to fall over when hit or collided, causing safety accidents; fifth, if drying is used, it takes a long time and the work efficiency is low. If drying is used, the drying temperature is low, which wastes energy and also makes the temperature in the working environment high.
