Description

Technical Field

[0001] The utility model relates to the technical field of cleaning concrete on the surface of steel bars, in particular to a concrete residue cleaning device. Background Art

[0002] A rebar cleaning device is a specialized tool or device designed to remove dirt, rust, loose concrete, and other impurities from the surface of rebar. Its primary purpose is to ensure a good bond between the rebar and concrete, thereby improving the stability and durability of the structure.

[0003] In practice, once concrete begins to harden, its bond strength increases, making traditional cleaning methods like vibration and brushes less effective. Due to the higher hardness of hardened concrete, cleaning requires greater force and longer time, which undoubtedly increases the difficulty and complexity of cleaning.

[0004] While vibrating and brushing can partially remove slightly hardened concrete, this process can damage the surface of the rebar, which can weaken the bond between the rebar and concrete, affecting the overall stability of the structure.

[0005] Due to the strong adhesive properties of hardened concrete, even methods like vibration and brush cleaning may not be able to completely remove it. This can cause concrete residue to form a film on the rebar surface, affecting bonding. Cleaning slightly hardened concrete is not only difficult but also requires more manpower, material resources, and time, increasing cleaning costs and reducing construction efficiency. Furthermore, the longer cleaning time required for slightly hardened concrete can negatively impact the overall construction schedule, leading to extended construction periods. Utility Model Content

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] Example 1

[0027] In this embodiment, a device for cleaning concrete residue is shown, and its structure is as follows: Figures 1 to 4 The device consists of three core components: a bracket 1, an adjustment bracket 2, and a high-pressure nozzle 4. The adjustment bracket 2 is mounted in the middle of the upper end of the bracket 1, while the high-pressure nozzle 4 is fixed to the adjustment bracket 2 to perform high-pressure washing on the concrete surface of the steel bars.

[0028] Bracket 1 is provided with a sleeve 7 at each end, each housing a rotating rod 6. Each rotating rod 6 is fitted with a retaining nut 8. One rotating rod 6 is connected to a first clamp 9 via a connector 5, while the other rotating rod 6 is connected to a second clamp 10 via a connector 5. Rebar with concrete residue can be passed through these two clamps and cleaned by a high-pressure nozzle 4. The angles of the first and second clamps 9, 10 can be adjusted by rotating the rotating rods 6 to accommodate rebar of varying sizes.

[0029] Two semi-circular connecting covers 11 are installed inside each of the first and second clamps 9, 10. A cleaning brush 13 is mounted on the connecting cover 11 of the first clamp 9, while a cleaning wire brush 14 is mounted on the connecting cover 11 of the second clamp 10. When rebar with concrete residue passes through these two sets of connecting covers 11, the rebar surface comes into contact with the cleaning brushes 13 and 14, thereby cleaning the rebar surface.

[0030] The rotating rod 6 and connector 5 are integrated into one design, consisting of three sections: an externally threaded portion, a smooth middle portion, and an internally threaded portion. Two limit nuts 8 are fitted over the externally threaded and internally threaded portions, respectively, while the smooth middle portion is positioned within the opening of the sleeve 7. The first and second clamps 9 and 10 are identical in structure, and the two connecting covers 11 are combined to form a complete annular cover, secured to the respective clamps by bolts. The two connecting covers 11 position or release the rebar containing concrete debris as the clamps open and close.

[0031] A blocking block 12 is provided at the opening of the connecting cover 11 to limit the interlaced movement of the two connecting covers 11. A plurality of cleaning wire brushes 14 are welded equidistantly on one of the connecting covers 11, while a plurality of cleaning brushes 13 are equidistantly arranged and connected to the other connecting cover 11 by hot melt.

[0032] Example 2

[0033] In another embodiment, the adjustment frame 2 is made of a bendable metal material, with multiple mounting holes 3 formed on its end surface. The high-pressure nozzle 4 is fixed to the adjustment frame 2 via nuts. The adjustment frame 2 and the bracket 1 are perpendicular to each other and are fixed together with bolts to ensure the stability of the device and the convenience of operation.

[0034] The usage process is as follows: Pass the steel bar with concrete residue through the first clamp 9 and the second clamp 10. Adjust the angle of the first clamp 9 and the second clamp 10 to adapt to the size of the steel bar. This can be achieved by rotating the connector 5 and the rotating rod 6. Ensure that the steel bar is firmly fixed in the clamp for cleaning operation. Start the high-pressure nozzle 4 and perform high-pressure flushing on the surface of the steel bar to remove concrete residue. During the flushing process, the surface of the steel bar will come into contact with the cleaning brush 13 and the cleaning wire brush 14, further cleaning the surface of the steel bar. The rotation of the rotating rod 6 is controlled by the limit nut 8 to ensure the appropriate rotation range. The blocking block 12 limits the staggered movement of the connecting cover 11 to ensure the smooth progress of the cleaning process. In another embodiment, the adjustment frame 2 is fixed to the bracket 1 by bolts to ensure the stability of the device and the convenience of operation. The entire process is achieved through the coordinated work of the bracket 1, the adjustment frame 2 and the high-pressure nozzle 4 to effectively clean the concrete residue on the surface of the steel bar.
