Technical Field

[0001] This invention relates to the field of concrete construction technology, and in particular to a roughening device for processing precast concrete slabs. Background Technology

[0002] During the processing of precast concrete slabs, it is usually necessary to roughen their surface to enhance their roughness and provide better adhesion for the next construction process. Existing roughening equipment includes automated roughening machines for mass production of precast slabs, but due to their complex structure, high operating costs, and difficulty in controlling flexibility, they are inconvenient to use. Therefore, manual roughening tools are still widely used on some construction sites. However, manual roughening tools, due to their fixed structure, cannot adjust the roughening depth and cannot be flexibly adjusted to meet different needs, thus limiting their application.

[0022] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0023] like Figures 1 to 6 As shown, the present invention discloses a roughening device for processing precast concrete slabs, comprising a housing 1, the housing 1 having a hollow structure and an adjustable mounting plate 2 inside. A plurality of roughening rods 3 are evenly arranged at the bottom of the mounting plate 2. The bottom ends of the roughening rods 3 pass through the housing 1 and are located below the housing 1. By adjusting the position of the mounting plate 2, the length of the roughening rods 3 extending beyond the housing 1 can be adjusted, thereby adjusting the roughening depth. The device is simple to operate and highly practical. Preferably, the bottom end of the roughening rods 3 is designed with a smooth surface and a pointed tip to quickly penetrate the uncured concrete and avoid causing significant disturbance to the concrete surface of the precast slab. An adjustable operating rod 4 is hinged to one side of the housing 1 to adjust its length as needed.

[0024] Furthermore, a screw 5 is provided at the center of the top of the mounting plate 2. The top of the screw 5 extends to the top of the housing 1 and is threadedly connected to an adjusting screw 6 rotatably mounted on the top of the housing 1. By rotating the adjusting screw 6, the screw 5 can be raised or lowered, thereby driving the buffing rod 3 to rise or fall, thus adjusting the amount of the buffing rod 3 extending from the bottom of the housing 1 to meet different usage needs and enhance the flexibility of the invention. Guide rods 7 are provided at each of the four corners of the mounting plate 2. The top of the guide rods 7 extends movably from the top of the housing 1 and provides limiting guidance for the vertical movement of the mounting plate 2. A buffer rod 8 is provided at the top of the mounting plate 2. A buffer cavity 9 is opened at the bottom of the screw 5 extending upward. The buffer rod 8 is set in the buffer cavity 9 through a buffer spring 10. A pull rod 11 is provided between the two guide rods 7 on each side. By pulling the pull rod 11, the guide rod 7 is raised, and the buffer spring 10 is compressed under the upward movement of the buffer rod 8. The design allows the textured rod 3 to move up and down relative to the housing 1, facilitating the removal of concrete from the exterior of the textured rod 3 after use and enhancing the practicality of the invention. A through hole is provided at the bottom of the housing 1 opposite to the textured rod 3, and a cleaning sleeve 12 extends downward from the through hole, through which the textured rod 3 moves. The bottom of the cleaning sleeve 12, where it contacts the textured rod 3, is narrowed to allow for the removal of concrete adhering to the exterior of the textured rod 3 when the pull rod 11 is pulled up and down. Furthermore, a limiting block 28 is provided on the buffer rod 8, and a limiting groove 29 matching the limiting block is provided in the buffer cavity. The limiting block 28 is slidably disposed within the limiting groove 29. The limiting block 28 and the limiting groove 29 limit the movement of the buffer rod 8, ensuring its stability within the buffer cavity 9.

[0025] Furthermore, both sides of the housing 1 are provided with storage slots 13, and each storage slot 13 is movably provided with an installation rod 14. The housing 1 inside the storage slot 13 is provided with a slide for the installation rod 14 to slide. By pulling the installation rod 14 to slide it, the brushing roller 15 can be received or removed in the storage slot 13. A collar 16 is rotatably provided on the installation rod 14, and the brushing roller 15 is movably provided in the collar 16. The inner diameter of the collar 16 is larger than the outer diameter of the brushing roller, and the two do not contact each other. The brushing roller 15 is rotatably mounted on a mounting frame 17 that is open on one side. The mounting frame 17 can be U-shaped. The design can be either L-shaped or T-shaped; the collar 16 is detachably connected to the mounting bracket 17; the setting of the roughening roller 15 can meet the roughening operation of the side of the cement board, enhancing the practicality of the invention and expanding its application range; when it is necessary to roughen the side of the cement board, the roughening roller 15 can be pulled out from the storage groove 13, and then the collar 16 can be rotated so that the roughening roller 15 is perpendicular to the storage groove 13, and placed on one side of the cement board so that it contacts the side of the cement board, and the operation rod 4 can be pulled to move it to realize the roughening operation of the side of the cement board, enriching the function of the invention and enhancing its practicality. Preferably, a fixing frame 18 is provided on the collar 16, and sliders are symmetrically arranged inside the fixing frame 18. A groove 19 is provided on the mounting frame 17 opposite to the slider, and the slider slides within the groove 19. A locking bolt 20 is provided on one side of the fixing frame 18 to lock the mounting frame 17 and ensure the stability of the texturing roller 15 after adjustment. By sliding the mounting frame 17 and the fixing frame 18, the height of the texturing roller 15 can be adjusted to meet the side texturing operation of cement boards of different thicknesses, thereby improving the practicality of the present invention.

[0026] The mounting rod 14 has symmetrically arranged receiving cylinders 21 on its upper and lower sides. A positioning rod 23 is connected to the receiving cylinder 21 through a compression spring 22. A ball bearing 24 is movably arranged at the end of the positioning rod 23. A corresponding moving groove 25 is arranged on the receiving shell 1 inside the storage groove 13. Both ends of the moving groove 25 are provided with positioning grooves 26. When the brushing roller 15 is stored in the storage groove 13, the ball bearing 24 is located in the inner positioning groove 26. When the brushing roller 15 needs to be used, the ball bearing 24 of the brushing roller 15 is pulled out from the inner positioning groove 26 until it enters the outer positioning groove 26 for repositioning. At this time, the position of the brushing roller 15 can be adjusted by rotating. The operation is simple and the practicality is strong. In addition, each positioning groove 26 is provided with an inclined slope 27 connected to the moving groove 25. The inclined slope 27 facilitates the movement of the ball 24 out of the positioning groove 26 and provides a buffer for the movement of the ball 24 from the positioning groove 26 to the moving groove 25, thereby improving the convenience of the folding roller 15 storage operation.

[0027] When using this invention, if it is necessary to adjust the length of the grouting rod 3 extending out of the housing 1, simply rotate the adjusting screw 6. When it is necessary to use the grouting roller 15 to grout the side of the precast slab, the grouting roller 15 can be pulled out of the receiving groove 13. At this time, the ball bearing 24 on the positioning rod 23 will move out of the inner positioning groove 26 and into the outer positioning groove 26. Then, rotate the collar 16. Since the mounting bracket 17 of the grouting roller 15 is connected to the collar 16, it will drive the grouting roller 15 and the mounting bracket 17 to complete the position conversion operation synchronously. At this time, the position of the grouting roller 15 can be adjusted according to the thickness of the precast slab. The operation is simple and quick. After use, the pull rod 11 can be pulled up and down to drive the grouting rod 3 to pass through the cleaning sleeve 12 at the bottom of the housing 1 to complete the cleaning operation of the concrete adhering to the outside of the grouting rod 3. The operation is simple and practical.
