[0029] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figure 1 , Figure 4 and Figure 5 A concrete formwork clamp, as shown, includes: a support frame, an upper connector 2, and a lower connector 3. The support frame includes a first vertical rod 1 and a second vertical rod 4 arranged in parallel. The upper connector 2 and the lower connector 3 are arranged in parallel. The upper connector 2 includes a first screw 211, a first spiral buckle 21 with positive and negative threads, a second screw 212, and a first horizontal rod 22 connected in a horizontal sequence. The first screw 211 is connected to the first vertical rod 1. The second vertical rod 4 is slidably mounted on the first horizontal rod 22. The first horizontal rod 22 has multiple second pin holes 221, and a first pin 5 is fitted into each of the second pin holes 221. The lower connector 3 includes a third screw 311 connected in a horizontal sequence. 1. A second spiral buckle 31, a fourth screw 313, and a second horizontal rod 32. A first vertical rod 1 has multiple first connecting holes 12. A third screw 3111 is installed in the first connecting hole 12. A second vertical rod 4 has multiple second connecting holes 41. A second horizontal rod 32 is slidably disposed on the second connecting hole 41. A second horizontal rod 32 has multiple third pin holes 321. A second pin 6 is fitted on the third pin hole 321. The two ends of the first spiral buckle 21 are threadedly connected to the first screw 211 and the second screw 212, respectively. The two ends of the second spiral buckle 31 are threadedly connected to the third screw 3111 and the fourth screw 313, respectively.

[0031] The aforementioned concrete formwork clamp, through the movable and adjustable second vertical rod 4, first horizontal rod 22 and second horizontal rod 32, in conjunction with the first screw 211, first positive and negative threaded screw buckle 21, second screw 212, third screw 3111, second positive and negative threaded screw buckle 31, fourth screw 313 and second horizontal rod 32, can be moved and adjusted simultaneously to achieve clamping and fixing of different concrete formwork. At the same time, after using the first pin 5 and second pin 6 for limiting, tightening the first positive and negative threaded screw buckle 21 and the second positive and negative threaded screw buckle 31 further achieves clamping and fixing of the concrete formwork. Moreover, the overall structure of the clamp is simple, the cost is low, it is easy to assemble, and the installation and disassembly process is convenient, making it easy to reuse, saving construction time, and improving the work efficiency of concrete formwork erection.

[0032] like Figure 1 and Figure 5As shown, in this embodiment, a plurality of first pin holes 11 are evenly provided on the first vertical rod 1, and a pin hole 311 is provided on the third screw 3111 near the first vertical rod 1. The clamp also includes a third pin 7, which is connected to the first pin holes 11 and the pin hole 311. By evenly providing a plurality of first pin holes 11, the clamping and fixing of concrete formwork of different sizes can be satisfied, improving the flexibility and practicality of the clamp. At the same time, the third pin 7 is used to fix and limit the third screw 3111 by connecting with the first pin holes 11 and the pin hole 311, thereby improving the stability of the clamp.

[0033] like Figure 1 As shown in this embodiment, the cross-sections of the first vertical rod 1 and the second vertical rod 4 are both rectangular. The rectangular design helps to increase the contact area between the first vertical rod 1 and the second vertical rod 4 and the concrete formwork, thereby enabling the inner sides of the first vertical rod 1 and the second vertical rod 4 to fit well and tightly with the concrete formwork, and improving the stability of the clamp.

[0034] like Figure 1 and Figure 2 As shown, in this embodiment, the cross-sections of the first horizontal bar 22 and the second horizontal bar 32 are both rectangular. The rectangular design of the first horizontal bar 22 and the second horizontal bar 32 helps to increase the contact area with the concrete formwork, thereby ensuring a good and tight fit between the inner sides of the first horizontal bar 22 and the second horizontal bar 32 and the concrete formwork, improving the stability of the clamp. Simultaneously, the cross-section of the second connecting hole 41 is rectangular. The rectangular design of the first horizontal bar 22 and the second horizontal bar 32 connects with the second connecting hole 41, allowing adjustment of the distance between the first vertical bar 1 and the second vertical bar 4, thus enabling the clamping of concrete formwork of different sizes. Furthermore, the first horizontal bar 22 and the second horizontal bar 32 have identical structures. The second pin holes 221 are evenly distributed on the first horizontal bar 22, and the third pin holes 321 are evenly distributed on the second horizontal bar 32. This even distribution helps to avoid stress concentration and also ensures the strength and rigidity of the first horizontal bar 22 and the second horizontal bar 32. Figure 2 The hole on the side of the first horizontal rod 22 is welded to the second screw 212. Similarly, the fourth screw 313 is welded to the second horizontal rod 32. The welding ensures the stability of the connection.

[0035] like Figure 1 and Figure 3 As shown, in this embodiment, the first pin 5, the second pin 6, and the third pin 7 are all T-shaped. The T-shaped design ensures the effectiveness of the pin limiting. Taking the first pin 5 as an example, the first pin 5 cooperates with the second pin hole 221 to achieve limiting, ensuring that the first horizontal rod 22 and the second vertical rod 4 are in a relatively fixed position. At the same time, the first pin 5 will not fall off in the horizontal direction, ensuring the effectiveness of the limiting connection of the first pin 5. The second pin 6 and the third pin 7 are based on the same principle as the first pin 5, so they will not be described in detail here.

[0036] like Figure 4 and Figure 5 As shown in this embodiment, the surfaces of the first screw 211, the second screw 212, the third screw 3111, and the fourth screw 313 are not all threaded. Only the parts that are connected to the second positive and negative threaded screw thread 31 or the first positive and negative threaded screw thread 21 are threaded, while the rest are smooth. The smooth design facilitates the connection between the first screw 211 and the third screw 3111 and the first vertical rod 1, and also facilitates the welding of the second screw 212 to the first horizontal rod 22 and the welding of the fourth screw 313 to the second horizontal rod 32.

[0037] like Figure 6 As shown, in this embodiment, during the reinforcement of the concrete formwork for raising the interior window sill of a building project, the positions of the lower connector 3 and the first vertical rod 1 are adjusted according to the actual site conditions. The third pin 7 is installed in conjunction with the pin hole 311. The two ends of the first positive and negative threaded spiral buckle 21 are respectively threaded to the first screw 211 and the second screw 212. The two ends of the second positive and negative threaded spiral buckle 31 are respectively threaded to the third screw 3111 and the fourth screw 313. Then, the formwork on both sides of the window sill is installed, the clamping device is placed above the formwork, and the second vertical rod is adjusted. 4. Align the first horizontal bar 22 and the second horizontal bar 32 with the second connecting hole 41. Then, use the first pin 5 to align with the second pin hole 221 for installation and fixation, and the second pin 6 to align with the third pin hole 321 for installation and fixation. Finally, tighten the first and second spiral buckles 21 and 31 to complete the formwork support and clamping reinforcement. After the concrete is poured and the conditions for removing the formwork are met, loosen the first and second spiral buckles 21 and 31, and pull out the first pin 5, the second pin 6 and the third pin 7 to remove the clamp.

[0038] like Figure 7 As shown, in this embodiment, when the clamp is applied to the indoor structural column formwork support and reinforcement scenario, the position of the lower connecting piece 3 and the first vertical rod 1 is adjusted according to the actual site conditions. The third pin 7 is installed in conjunction with the pin hole 311. The two ends of the first positive and negative threaded spiral buckle 21 are respectively threaded to the first screw 211 and the second screw 212. The two ends of the second positive and negative threaded spiral buckle 31 are respectively threaded to the third screw 3111 and the fourth screw 313. Then, the structural column formwork is installed, and the clamp is used to wrap around the formwork. The second vertical rod 4 is adjusted to make... The first horizontal bar 22 and the second horizontal bar 32 are engaged with the second connecting hole 41. Then, the first pin 5 is engaged with the second pin hole 221 for installation and fixation, and the second pin 6 is engaged with the third pin hole 321 for installation and fixation. Finally, the first and second spiral buckles 21 and 31 are tightened to complete the formwork support and clamping reinforcement. After the concrete is poured, when the conditions for removing the formwork are met, the first and second spiral buckles 21 and 31 are loosened, and the first pin 5, the second pin 6 and the third pin 7 are pulled out to remove the clamp.

[0039] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
