[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0018] This embodiment includes a rectangular block 1, which can be made of a lightweight plastic block with a thickness between 3-6 cm. A cross-shaped groove A2 is provided in the middle of the front face of the rectangular block 1. The cross-shaped groove A2 does not penetrate the rectangular block 1. The horizontal and vertical lengths of the cross-shaped groove A2 are designed to be the horizontal and vertical lengths required for applying anti-rust paint to the weld joint of the keel. The weld joint is painted through the cross-shaped groove A2. The weld joint is the intersection of the horizontal keel 4 and the vertical keel 5. Generally, the horizontal and vertical lengths for applying anti-rust paint to the weld joint should not be less than 5 cm. The horizontal and vertical lengths of the cross-shaped groove A2 can be designed according to the construction requirements. A cross-shaped groove B3 is provided on the rear face of the rectangular block 1. The cross-shaped groove B3 penetrates the rectangular block 1 in both the horizontal and vertical directions, but does not penetrate the rectangular block 1 in the thickness direction. The cross-shaped groove B3 is connected to the cross-shaped groove A2. The transverse groove width of the cross groove B3 is equal to the transverse groove width of the cross groove A2, and the longitudinal groove width of the cross groove B3 is equal to the longitudinal groove width of the cross groove A2. Furthermore, the transverse groove width and longitudinal groove width of both are equal to the width of the welded transverse keel 4 and the width of the welded longitudinal keel 5, respectively.

[0019] In this embodiment, the rectangular block 1 can be designed as one piece or multiple pieces. Multiple rectangular blocks 1 are connected together as a whole, and the distance between the cross grooves A2 of adjacent rectangular blocks 1 is equal to the distance between the welding points of adjacent keels. That is, multiple rectangular blocks 1 can correspond to multiple welding points of keels respectively.

[0020] In use, align the cross-shaped groove B3 of rectangular block 1 with the intersection of the horizontal keel 4 and the vertical keel 5, and then secure rectangular block 1 at the keel weld. The horizontal and vertical grooves of cross-shaped groove B3 are respectively secured to the horizontal keel 4 and the vertical keel 5. At this time, the worker holds a spray painting tool and sprays paint into the cross-shaped groove A2 with the front end of rectangular block 1 facing it. The spray painting tool can be a spray gun, spray painting machine, etc. The anti-rust paint sprayed is limited to the cross-shaped groove A2, and finally a sprayed area of ​​cross-shaped groove A2 is formed at the keel weld. The size of cross-shaped groove A2 is designed according to the area required by the anti-rust paint, so the size of the anti-rust paint at the keel weld is standardized and uniform, ensuring the construction quality and the quality of the keel in the later stage. To expedite the painting of weld joints, multiple rectangular blocks 1 can be used simultaneously. For example, in this embodiment, three rectangular blocks 1 connected together are used. The three keel weld joints can be aligned at once, and then the paint can be applied to the three cross grooves A2 one by one, completing the painting of the three weld joints in one go, further improving efficiency. In addition to using multiple rectangular blocks 1 horizontally as in this embodiment, multiple rectangular blocks 1 can also be designed to match the longitudinal weld joints, completing the painting of multiple weld joints in one go in the longitudinal direction.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
