Each set of connecting posts 18 has a left connecting block 19 at both ends, and a right connecting block 21 is engaged on one side of each left connecting block 19. The left connecting blocks 19 and right connecting blocks 21 engage with each other to form a connecting structure. Circular holes are formed on the left and right connecting blocks 19 and 21, and fixing posts 22 pass through these holes. The fixing posts 22 serve to penetrate and fix the left and right connecting blocks, enabling them to work together and jointly bear external forces. Nuts are fitted at both ends of the fixing posts 22, ensuring that they will not fall off and enhancing the reliability of the connection. A protective box 17 is fitted onto the upper card box 12 and the lower card box 11, effectively preventing the intrusion of dust, moisture, and other external substances. The protective box 17 can be connected to the upper clamping plate 15 and the lower clamping plate 16. Multiple sets of threaded posts 23 are provided between the upper clamping plate 15 and the lower clamping plate 16. These threaded posts 23 pass through the upper card box 12 and the lower card box 11 and are mounted on the upper clamping plate 15 and the lower clamping plate 16. The threaded posts 23 increase the connection strength between the clamping plate and the card box, allowing the clamping plate to be more firmly fixed to the card box. The multiple sets of upper clamping plates 15 and multiple sets of lower clamping plates 16 are all fixedly connected by bolts, ensuring that the clamping plates apply sufficient and uniform clamping force to the bridge formwork.

[0026] like Figures 2 to 5 As shown, when using this device, the user first uses the lower clamping box 11 as the bottom support structure of the entire device, bearing the main load-bearing task and providing a stable foundation for the components above. An upper clamping box 12 is mounted on the lower clamping box 11, and the upper clamping box 12 cooperates with the lower clamping box 11 to fix the bridge template. Grooves 13 are provided on both sides of the upper clamping box 12 and the lower clamping box 11 to facilitate operation and positioning during installation and disassembly. A limiting post 14 is provided between the upper clamping box 12 and the lower clamping box 11. The limiting post 14 restricts the relative position of the upper clamping box 12 and the lower clamping box 11, ensuring that they remain accurately aligned during use and do not shift. Multiple sets of upper clamping plates 15 are provided on the upper clamping box 12, and multiple sets of lower clamping plates 16 are provided at the bottom of the lower clamping box 11. The upper clamping plates 15 and the lower clamping plates 16 cooperate to apply a uniform and strong clamping force to the bridge template from both above and below, ensuring that the template is firmly fixed inside the device without loosening or displacement. Multiple sets of connecting components are provided on both sides of the upper card box 12 and the lower card box 11 to further enhance the stability of the connection between the upper card box 12 and the lower card box 11, thereby improving the overall load-bearing capacity and deformation resistance of the device.

[0027] The connecting assembly includes multiple sets of connecting posts 18, which pass through the upper card box 12 and the lower card box 11. Each set of connecting posts 18 has a left connecting block 19 at both ends, and a right connecting block 21 is engaged on one side of each left connecting block 19. The left connecting blocks 19 and right connecting blocks 21 engage to form a stable whole. Circular holes are formed on the left connecting blocks 19 and right connecting blocks 21, and fixing posts 22 pass through these holes. The fixing posts 22 play a crucial role in penetrating and fixing the left connecting blocks 19 and right connecting blocks 21, enabling them to work together and jointly withstand external forces from all directions. Nuts are fitted at both ends of the fixing posts 22. The tightening force of the nuts ensures that the fixing posts 22 will not fall off during use, enhancing the reliability and stability of the connection. The upper card box 12 and lower card box 11 are engaged for easy and rapid assembly on the construction site. Limiting posts 14 are inserted into the upper card box 12 and the lower card box 11 through corresponding holes, restricting the relative movement of the upper card box 12 and the lower card box 11 in the horizontal and vertical directions, ensuring the stability of the connection. A protective box 17 is fitted onto the upper card box 12 and the lower card box 11, effectively preventing the intrusion of external substances such as dust, moisture, and debris, providing comprehensive protection for the internal structure. The protective box 17 is connected to the upper clamping plate 15 and the lower clamping plate 16 by a snap-fit ​​mechanism. Multiple sets of threaded posts 23 are provided between the upper clamping plate 15 and the lower clamping plate 16, passing through the upper card box 12 and the lower card box 11 and onto the upper clamping plate 15 and the lower clamping plate 16. The threaded posts 23 increase the connection strength and stability between the clamping plate and the card box, allowing the clamping plate to be more firmly fixed to the card box, effectively preventing deformation or displacement of the clamping plate under stress. Multiple sets of upper clamping plates 15 and multiple sets of lower clamping plates 16 are all fixedly connected by bolts. By tightening the bolts, the clamping force on the template can be increased, ensuring that the template can be fixed in the device.

[0028] The specific usage and function of this embodiment are as follows:

[0029] When using this device, the user first places the lower clamping box 11 at the designated position on the bridge formwork. Then, the upper clamping box 12 is correspondingly engaged with the lower clamping box 11, and the limiting post 14 passes through the upper clamping box 12 and the lower clamping box 11 to provide initial positioning and prevent misalignment. Next, multiple sets of connecting posts 18 pass through the upper clamping box 12 and the lower clamping box 11, and left connecting blocks 19 are installed at both ends of the connecting posts 18. The right connecting block 21 is then engaged on the left connecting block 19. The fixing post 22 passes through the round holes on the left connecting block 19 and the right connecting block 21, and nuts are fitted onto both ends of the fixing post 22 and tightened to prevent the left connecting block 19 and the right connecting block 21 from misaligning or falling off under pressure. Multiple sets of upper clamping plates 15 and lower clamping plates 16 are fixed in their respective positions with bolts. Threaded posts 23 pass through the upper clamping box 12 and the lower clamping box 11 and connect with the upper clamping plates 15 and the lower clamping plates 16, further enhancing the clamping and fixing effect of the clamping plates on the formwork. The protective box 17 is fitted onto the upper card box 12 and the lower card box 11, and connected to the upper clamping plate 15 and the lower clamping plate 16. It protects the entire connection and locking device, reducing environmental erosion and damage. This device ensures a stable and reliable connection and locking of the bridge formwork. It effectively prevents loosening, displacement, and deformation of the formwork during construction, ensuring the quality of concrete pouring and improving the safety and efficiency of bridge construction. Furthermore, the device is detachable, facilitating installation, maintenance, and reuse, thus reducing construction costs.
