[0002] The three-wall formwork of a bridge refers to the precast formwork used for pouring parts such as the side wall, retaining wall, and protective wall of the bridge structure. It mainly includes three major parts: the A-wall formwork, the B-wall formwork, and the protective wall formwork. These formworks are usually made of high-strength and high-durability materials to ensure that they can withstand various complex environmental conditions and load requirements during use. When constructing the three walls of the bridge, vibration is used to remove the residual air bubbles in the concrete to prevent the air bubbles from affecting the protective effect of the wall.

[0003] However, in the process of implementing the related technical solutions, it is found that there are at least the following technical problems: When constructing the three walls of the bridge, concrete needs to be poured inside the formwork. After vibrating the concrete, some of the air bubbles in the concrete are not completely discharged and will adhere to the inner side of the formwork, thereby reducing the density and strength of the concrete wall and having a negative impact on the protective effect of the wall. Summary of the Utility Model

DETAILED DESCRIPTION

[0017] An embodiment of the present application discloses a device for removing residual bubbles on the surface of a concrete wall. By pulling the bubble outlet plate 21 up and down along the template in conjunction with the notches 22 and slots 23 on the bubble outlet plate 21, bubbles attached to the template can be brought out to the outside, thereby reducing the residual bubbles on the concrete wall and improving the protective effect of the wall.

[0018] To better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0019] Please refer to Figure 1 and Figure 2 , this embodiment provides a device for removing residual bubbles on the surface of a concrete wall, including a connecting vertical rod 10, a bubble removal end 20, and a handle 30. The bubble removal end 20 is detachably arranged at one end of the connecting vertical rod 10, and the handle 30 is detachably arranged at the other end of the connecting vertical rod 10. The bubble removal end 20 includes a bubble leading-out plate 21, a mounting seat 24, and a second mounting column 25. The bubble leading-out plate 21 is arranged at one end of the connecting vertical rod 10. The shape of the bubble leading-out plate 21 is arrow-shaped, and the bottom edge of the bubble leading-out plate 21 is sharpened. A plurality of notches 22 are formed on the side of the bubble leading-out plate 21 away from the connecting vertical rod 10, and a plurality of through holes 23 are symmetrically formed on the bubble leading-out plate 21. By driving the bubble leading-out plate 21 to move up and down along the formwork through the handle 30, the arrow-shaped and sharpened bubble leading-out plate 21 can be smoothly inserted into the concrete. Through the up and down movement of the bubble leading-out plate 21, the notches 22 and through holes 23 bring the bubbles attached to the inner wall of the formwork to the outside, reducing the residual bubbles on the concrete wall and improving the protection effect of the wall. When the bubble leading-out plate 21 moves up and down, the notches 22 accommodate the embedded parts on the formwork, so that the bubble leading-out plate 21 can remove the bubbles around the embedded parts of the formwork, improving the bubble removal effect.

[0020] Please refer to Figures 1 - 4 , the connecting vertical rod 10 includes a fixed column 11, a first mounting groove 12, and a threaded rod 14. The fixed column 11 is arranged between the bubble leading-out plate 21 and the handle 30. The size of the fixed column 11 matches the thickness of the bubble leading-out plate 21, so that when the fixed column 11 closely adheres to the formwork and extends into the concrete, the bubble leading-out plate 21 can closely adhere to the formwork, thereby removing the bubbles in the formwork. A threaded groove 13 is formed at one end of the fixed column 11, and the threaded rod 14 is threadedly connected to the inside of the threaded groove 13. The bubble leading-out plate 21 is detachably arranged at one end of the threaded rod 14. By rotating the threaded rod 14 in the threaded groove 13, the length of the threaded rod 14 extending from the fixed column 11 is changed, and the overall length of the bubble removal device is changed to adapt to formworks of different lengths. By observing whether the fixed column 11 closely adheres to the inner wall of the formwork, it can also be judged whether the bubble leading-out plate 21 inserted into the concrete closely adheres to the inner wall of the formwork for bubble removal work, improving the bubble removal effect.

[0021] Please refer to Figures 1 - 4, a first mounting post 40 is fixedly arranged near the middle of the handle 30 close to the fixed post 11. A first mounting groove 12 is formed at one end of the fixed post 11 close to the handle 30. The first mounting post 40 is threadedly connected to the inside of the first mounting groove 12. The mounting seat 24 is fixedly arranged on one side of the bubble lead-out plate 21 close to the fixed post 11. A second mounting post 25 is fixedly arranged at one end of the mounting seat 24. A second mounting groove 15 is formed at one end of the threaded rod 14. The second mounting post 25 is threadedly connected to the inside of the second mounting groove 15. By rotating the first mounting post 40 on the handle 30 in the first mounting groove 12, the handle 30 and the fixed post 11 can be disassembled, and the fixed post 11 can be replaced, so that the extendable lengths of the fixed post 11 and the threaded rod 14 are changed, improving the adaptability to the length of the template. By rotating the second mounting post 25 in the second mounting groove 15, the bubble lead-out plate 21 can be detached from the threaded rod 14, so as to change the size of the notch 22 on the bubble lead-out plate 21, enabling the notch 22 to accommodate embedded parts of different sizes and positions, thereby improving the applicability of the bubble removal device.

[0022] The functional principle of the present application can be elaborated through the following operation modes:

[0023] During use, select a suitable bubble extraction plate 21 according to the size of the embedded parts on the bubble removal template to be cleaned. Then, rotate the fixed column 11 within a suitable length range according to the height of the template. Screw the first mounting column 40 on the handle 30 into the first mounting groove 12 on the fixed column 11 so that the handle 30 is mounted on the fixed column 11. Screw the second mounting column 25 on the mounting seat 24 into the second mounting groove 15 on one side of the threaded rod 14 so that the bubble extraction plate 21 is mounted on the threaded rod 14. Rotate the threaded rod 14 according to the height of the template so that the threaded rod 14 screws out of the fixed column 11, so that the overall length of the fixed column 11 and the threaded rod 14 can adapt to the template height. Hold the handle 30 and insert the fixed column 11 and the bubble extraction plate 21 along the inner wall of the template into the vibrated concrete. The fixed column 11 is in close contact with the template so that the bubble extraction plate 21 extending into the concrete is in close contact with the template. Pull the bubble extraction plate 21 up and down, and the bubbles attached to the template are taken out of the outside through the up and down movement of the notch 22 and the slot hole 23 on the bubble extraction plate 21. The embedded parts on the template are accommodated in the notch 22 on the bubble extraction plate 21 when the bubble extraction plate 21 moves up and down, so that the bubble extraction plate 21 can perform bubble removal work on the template around the embedded parts, reduce the bubble residue on the concrete wall, and improve the protection effect of the wall. When cleaning the templates around embedded parts of different sizes and templates of different heights, the second mounting column 25 in the second mounting groove 15 can be screwed out, and the bubble extraction plate 21 with a suitable notch 22 size can be replaced to adapt to embedded parts of different sizes. Rotate the threaded rod 14 to change the overall length of the fixed column 11 and the threaded rod 14. When the length range of the fixed column 11 is inappropriate, screw the handle 30 out of the first mounting groove 12 and replace the fixed column 11 with a different length range to adapt to the bubble removal work of templates of different heights.
