Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a demarcation and isolation device for painting edge protection railings at construction sites. Background Technology

[0002] Construction work involves numerous operations near edges, making edge protection a crucial safety measure for construction workers. Edge protection typically consists of guardrails, toe boards, and dense mesh netting. Red and white striped guardrails significantly improve the visibility of the protection, reinforce safety awareness among on-site workers, and enhance the overall appearance of the construction site. Therefore, they are widely used on construction sites.

[0003] However, when painting guardrails, workers first need to evenly apply paint to the guardrail, then stick masking tape on the painted surface, apply another type of paint, and then peel off the masking tape to form a clear dividing line. This process is tedious and prone to errors, and also consumes a lot of masking tape, increasing construction costs and causing environmental pollution. To solve the above problems, this utility model provides a painting boundary isolation device for edge protection guardrails on construction sites, aiming to achieve fast, accurate, and environmentally friendly painting boundary separation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides the following technical solution: a demarcation and isolation device for painting the edge protection railing at the construction site, comprising: two semi-cylindrical sleeves 10, the arc-shaped openings of the two semi-cylindrical sleeves 10 being arranged opposite each other, the two semi-cylindrical sleeves 10 being able to be connected together to form a cylindrical sleeve, and the two semi-cylindrical sleeves 10 being able to be fitted onto the railing.

[0023] The semi-cylindrical sleeve 10 has semi-circular fixed sleeves 21 installed at both ends. The semi-circular fixed sleeves 21 can be fitted onto the guardrail. Fixed blocks 22 are spaced apart on the outer circumference of the semi-circular fixed sleeve 21. Fasteners are provided on the fixed blocks 22. One of the fixed blocks 22 has a threaded hole, and the other fixed block 22 has a through hole. The fastener is a screw 23 with threads set in the threaded hole. A nut 231 is threaded onto one end of the screw 23 that passes through the through hole.

[0024] Please continue reading. Figure 1-5Two semi-circular fixing sleeves 21 are fitted onto the guardrail and tightened with screws 23 and nuts 231 to ensure the stability of the device. The arc-shaped openings of the semi-cylindrical sleeves 10 face each other to form a cylindrical sleeve, which is convenient to fit onto the guardrail and realize the separation of painting boundaries.

[0025] A through groove 11 is provided on the semi-cylindrical sleeve 10. A connecting post 13 is slidably provided inside the groove 11. A limiting groove 19 is provided inside the semi-cylindrical sleeve 10. A limiting block 20 is slidably provided inside the limiting groove 19. The limiting block 20 is connected to the outer circumferential surface of the connecting post 13. Through the cooperation of the limiting groove 19 and the limiting block 20, the connecting post 13 is ensured to move stably within the groove 11, preventing the device from shifting during the painting process.

[0026] Please see Figure 1-3 The connecting column 13 has a paint brush at one end that extends into the semi-cylindrical sleeve 10. The paint brush is used to paint the guardrail. Semi-circular sealing rings 12 are installed at both ends of the semi-cylindrical sleeve 10. The semi-circular sealing rings 12 are used to prevent the paint inside the semi-cylindrical sleeve 10 from leaking out, thereby isolating it from the external environment and ensuring that the painting process is efficient and clean.

[0027] The painting component is a semi-circular scraper 14 installed on one end of the connecting column 13 that extends into the semi-cylindrical sleeve 10. The end of the semi-circular scraper 14 away from the guardrail is in close contact with the inner wall of the semi-cylindrical sleeve 10. The side of the semi-circular scraper 14 facing the guardrail is provided with bristles 15, which are evenly distributed to ensure uniform painting.

[0028] The semi-circular scraper 14 has a receiving groove 16 for holding paint inside. The brush bristles 15 extend into the receiving groove 16. The connecting post 13 has a connecting groove 17 that runs from left to right inside. The connecting groove 17 is connected to the receiving groove 16. The connecting post 13 is provided with a cover plate 18. When the cover plate 18 is opened, paint can be injected into the connecting groove 17. The paint flows into the receiving groove 16 through the connecting groove 17. The brush bristles 15 pick up the paint, achieving efficient painting.

[0029] The inner wall of the cover plate 18 is provided with internal threads, and the outer circumferential surface of the connecting column 13 is provided with external threads. The internal threads and external threads are compatible. By rotating the cover plate 18, it is tightly screwed into the connecting column 13 to ensure that the paint does not leak out.

[0030] Please see Figure 1-5 Working principle: When using it, first apply paint to the guardrail. After the paint dries slightly, put the two semi-cylindrical sleeves 10 on the guardrail and tighten the screws 23 and nuts 231 to fix the device.

[0031] It is particularly important to note that at this time, the semi-circular sealing ring 12 is fitted onto the part of the guardrail that has already been painted, ensuring that the semi-circular sealing ring 12 fits tightly against the guardrail, while also ensuring that there are no gaps between the two types of paint, thus forming a clear dividing line.

[0032] Next, open the cover plate 18 and inject an appropriate amount of another type of paint. The paint enters the connecting groove 17 and flows into the receiving groove 16 through the connecting groove 17. After the brush bristles 15 are dipped in the paint, they push the connecting column 13 to move smoothly in the sliding groove 11. The brush bristles 15 are in close contact with the surface of the guardrail and the paint is applied evenly. Guided by the inner wall of the semi-cylindrical sleeve 10, the brush bristles 15 always maintain the contact area with the guardrail to ensure the painting effect.

[0033] The brush bristles 15 move along the inner wall of the semi-cylindrical sleeve 10 to the semi-circular sealing ring 12, creating a clear dividing line between the two paints, with no obvious blank areas between them. During the movement of the brush bristles 15, the tight fit of the semi-circular sealing ring 12 effectively prevents paint overflow and mixing, ensuring a clean and clear dividing line.

[0034] After the paint is applied, loosen nut 231 and remove the device. At this point, the surface of the guardrail will show a clear boundary between the two paints, which is neat and beautiful. Repeat the above steps to continuously complete the painting work of multiple sections of guardrail. The operation is simple and efficient, which greatly improves work efficiency and painting quality.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
