[0002] Bridge formwork is steel formwork used in bridge projects, mainly for highway bridges, viaducts, and overpasses. Bridge formwork can be divided into highway bridge formwork and railway bridge formwork according to different conditions, and further subdivided into single and double-cell box girders (large box girders and small box girders), pier columns, pier column formwork, abutments, cap beams, T-shaped bridge formwork, etc. These formworks play a role in fixing and shaping concrete during bridge construction. They are temporary structures when pouring concrete and are usually made of wood, steel plates, or plastic materials.
[0003] When building bridges, concrete needs to be poured into the bridge formwork to solidify into bridge columns. However, existing bridge formwork does not have the function of connection and locking, and its structure is relatively simple and its application range is relatively limited. As a result, it is impossible to adjust the connection and locking range according to the needs of use, and the stability of the bridge formwork is too poor, which makes it easy to loosen during concrete pouring.

[0006] The first reinforcement and adjustment mechanism includes arc-shaped reinforcement plates arranged around the template. A locking moving block is fixedly connected to one side of each of the four arc-shaped reinforcement plates, and a locking positioning plate is provided inside the locking moving block.
[0007] The first position fixing mechanism includes a square positioning block disposed inside the locking moving block. The square positioning block is internally threaded with a first bolt. The locking positioning plate is provided with multiple positioning square grooves that cooperate with the square positioning block at equal intervals. The locking positioning plate is provided with a first threaded hole inside the positioning square groove.
[0008] The second position fixing mechanism includes a second bolt that is internally threaded to the locking moving block, and the locking positioning plate has multiple second threaded holes that mate with the second bolt at equal intervals inside.
[0009] The second reinforcement adjustment mechanism includes two covering blocks located on the outside of the two locking positioning plates, and four third bolts are threadedly connected to the inside of the two covering blocks.
[0010] The docking mechanism includes four inner groove docking blocks that are fixedly connected to one side of one of the covering blocks, and a raised docking block that mates with the inner groove docking blocks that is fixedly connected to one side of another covering block. The third bolt is threadedly connected to both the inner groove docking blocks and the raised docking blocks.
[0011] Among them, two first limiting blocks are fixedly connected to the inner side of the locking moving block, and the locking positioning plate has a first limiting groove that cooperates with the first limiting blocks inside.
[0012] This utility model has at least the following beneficial effects:
[0013] By incorporating a first reinforcing adjustment mechanism, which can be positioned around the two formwork panels, a locking force can be applied to the perimeter of the two formwork panels to prevent loosening during concrete pouring and thus ensure the smooth progress of the pouring work. Furthermore, by incorporating a first position fixing mechanism, a second position fixing mechanism, a second reinforcing adjustment mechanism, and a docking mechanism, the position of the first reinforcing adjustment mechanism can be adjusted using the reinforcing mechanism after the two formwork panels are locked in place, thus achieving a secure connection. These features broaden the applicability of the device, diversify its structure, and ensure the effective locking and fixing of the connection. Attached Figure Description

In use, by providing the first reinforcing adjustment mechanism 2, it is possible to... The device is positioned around the two templates 1 to provide a locking force, preventing loosening during concrete pouring and ensuring the smooth progress of the pouring process. With a first position fixing mechanism 3, a second position fixing mechanism 4, a second reinforcement adjustment mechanism 5, and a docking mechanism 6, the first reinforcement adjustment mechanism 2 can be adjusted to connect and lock the two templates 1 after locking them in place. This design allows for wider application and more diverse structures while ensuring effective locking.
[0026] The first reinforcement adjustment mechanism 2 includes arc-shaped reinforcement plates 21 arranged around the template 1. A locking moving block 22 is fixedly connected to one side of each of the four arc-shaped reinforcement plates 21. A locking positioning plate 24 is provided inside the locking moving block 22. In use, the arc-shaped reinforcement plates 21 are pressed tightly against the outside of the template 1. When it is necessary to adjust the position of the arc-shaped reinforcement plates 21, the locking moving block 22 can be pulled to move to the desired position outside the locking positioning plate 24.
[0027] The first position fixing mechanism 3 includes a square positioning block 31 disposed inside the locking moving block 22. The square positioning block 31 is internally threaded with a first bolt 32. The locking positioning plate 24 has multiple positioning square grooves 33 equidistantly arranged inside, which cooperate with the square positioning block 31. The locking positioning plate 24 has a first threaded hole 34 inside the positioning square grooves 33. In use, the square positioning block 31 is inserted into the locking moving block 22, and the square positioning block 31 cooperates with the positioning square grooves 33 in the locking positioning plate 24 to fix the position of the locking moving block 22. Then, the first bolt 32 is used to cooperate with the first threaded hole 34 in the locking positioning plate 24 to reinforce the position of the arc-shaped reinforcing plate 21.
