DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The embodiment of this application discloses a tooling for controlling the joint of the bridge deck protective wall. Through the sliding of the movable plate 22 in the square groove 211, the steel bars can be accommodated in the groove 221 on the movable plate 22. Through the sliding of the slider 23 in the chute 212, the movement of the movable plate 22 is positioned, so that the movable plate 22 can move smoothly to a suitable position, thereby preventing the situation where the groove 221 cannot accommodate the steel bars.

[0018] In order 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 embodiments.

[0019] Please refer to Figure 1 and Figure 2, this embodiment provides a tool for controlling the discontinuous joint of the bridge deck protection wall, which includes a middle plate 10 and two side plates 20. The middle plate 10 and the two side plates 20 are arranged at the discontinuous joint. A first extraction hole 11 is opened at the top of the middle plate 10. The first extraction hole 11 is arranged at a position on the top of the middle plate 10 higher than the side plate 20. A vertical groove 12 is opened at the bottom of the middle plate 10. When the middle plate 10 is inserted from the top, the vertical groove 12 can accommodate the steel bars on the protection wall, so that the middle plate 10 can be smoothly inserted into the discontinuous joint position. A plurality of bolt holes 30 are opened on both the middle plate 10 and the side plates 20. The plurality of bolt holes 30 correspond to the threaded holes at both side edges of the side formwork. The middle plate 10 and the side plates 20 are connected to the side formwork through the bolts in the bolt holes 30, playing a role in strengthening the formwork. The two sides of the middle plate 10 need to be polished before installation to remove rust and sundries, and a release agent is applied to ensure that the middle plate 10 is smooth and free of sundries before installation, so that when the forklift pulls the first extraction hole 11, the middle plate 10 can be smoothly pulled out upward from between the two side plates 20, making the disassembly of the tool more convenient. Although the friction between the middle plate 10 and the side plates 20 is sliding friction, due to the extrusion of the concrete at both ends, the frictional force is still very large, and the middle plate 10 will not move randomly between the two side plates 20.

[0020] Please refer to Figures 1 - 4 , the side plate 20 includes a pulling plate 21, a movable plate 22, a slider 23, a positioning block 24, a handle 25, and a second extraction hole 26. The pulling plate 21 is arranged on one side of the middle plate 10. A plurality of bolt holes 30 are opened on the pulling plate 21, and the positions of the bolt holes 30 on the middle plate 10 and the pulling plate 21 are matched. A square groove 211 is opened in the middle of one side of the pulling plate 21. The movable plate 22 is slidably connected to the inside of the square groove 211, and the size of the movable plate 22 matches that of the square groove 211. Grooves 221 are opened at the top and bottom of the side of the movable plate 22 close to the pulling plate 21. The two grooves 221 communicate with the square groove 211. When the movable plate 22 slides in the square groove 211, when the movable plate 22 completely extends into the square groove 211 on the pulling plate 21, the steel bars on the protection wall can pass through the groove 221 at one end of the movable plate 22, so that the pulling plate 21 and the movable plate 22 wrap the steel bars to prevent the concrete from leaking from the notch during pouring.

[0021] Please refer to Figures 1 - 4, sliding grooves 212 are provided on the inner walls of the top and bottom of the square groove 211. Two sliders 23 are respectively arranged on the top and bottom of the movable plate 22. The movable plate 22 is slidably connected to the inside of the sliding groove 212. A positioning groove 213 is provided on the inner wall of the middle part of the square groove 211. A positioning block 24 is arranged on the side of the movable plate 22 close to the pull plate 21. The positioning block 24 is matched with the positioning groove 213 in size. Two handles 25 are respectively arranged on the pull plate 21 and the side of the movable plate 22 away from the middle of the pull plate 21. A second extraction hole 26 is provided in the middle of the handle 25. By sliding the slider 23 on the movable plate 22 in the sliding groove 212, the sliding of the movable plate 22 in the square groove 211 is limited. When the positioning block 24 on the movable plate 22 is inserted into the positioning groove 213 during the installation, the position of the movable plate 22 in the square groove 211 can be more accurate, so as to ensure that the position of the groove 221 can accurately accommodate the steel bars on the protective wall, preventing the situation that the steel bars cannot be accommodated due to the inaccurate position of the groove 221. Through the handles 25 and the second extraction holes 26 on the pull plate 21 and the movable plate 22, the pull plate 21 and the movable plate 22 can be pulled out from both sides during disassembly, making the disassembly of the tooling faster.

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

[0023] During use, the middle plate 10 is polished on both sides and coated with a release agent before installation to ensure smoothness. Then, the side mold, end face, and crack control tooling are installed. The vertical grooves 12 at the bottom of the middle plate 10 are aligned with the positions of the steel bars in the protective wall. The middle plate 10 is moved down from the top of the crack, so that the steel bars are accommodated inside the vertical grooves 12. The two pull plates 21 are placed on both sides of the middle plate 10 from the opening direction of the square groove 211, so that the two steel bars are accommodated inside the square groove 211. Then, the slider 23 on the top of the movable plate 22 is aligned with the sliding groove 212 on the square groove 211, so that the movable plate 22 can slide inside the square groove 211. The sliding of the slider 23 in the sliding groove 212 limits the movable plate 22. When the positioning block 24 on one side of the movable plate 22 is inserted into the positioning groove 213, the pull plate 21 and the movable plate 22 are installed together. Then, bolts are screwed into the bolt holes 30 on the middle plate 10 and the pull plate 21 to fix the middle plate 10 and the two pull plates 21 to the side mold. After the concrete is poured, the bolts are removed first, and then the middle plate 10 is pulled out upward from the first extraction hole 11 at the top of the middle plate 10 by a forklift, and the pull plate 21 and the movable plate 22 are pulled out from both sides from the second extraction holes 26 on the handles 25 on one side of the pull plate 21 and the movable plate 22 to complete the disassembly work, making the disassembly and turnover more convenient.

[0024] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these changes and modifications.

[0025] The above are only the preferred specific embodiments of the embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution and its concept of the present application, makes equivalent substitutions or changes, and should be covered by the protection scope of the present application.
