Although this method is common, it also has some significant disadvantages. The drilling operation will cause damage to the formwork material, reduce the reuse rate of the formwork, increase construction costs, and the process is cumbersome and time-consuming, which affects the overall construction progress. Traditional fixing methods may have problems such as loose fixation and easy loosening, affecting the stability and safety of the formwork system. Traditional formwork systems are difficult to adapt to building structures of different sizes and shapes, which limits their application in diverse construction environments.

[0026] Preferably, multiple pulling mechanisms 4 can be positionally adjusted between multiple pulling holes 3 according to actual needs, which can not only connect multiple limiting plastic templates 1 more quickly and firmly, improve the installation efficiency of the limiting plastic templates 1, and reduce the installation difficulty, but also limit the limiting plastic template 1 without perforating the limiting plastic template 1, thereby improving the recovery rate of the limiting plastic template 1 and reducing the construction cost.

[0027] like Figure 3-Figure 5 As shown, a front telescopic sliding hole 5 is opened inside the outer side of the front end of the pulling hole 3, and an anti-loosening block 8 is slidably connected inside the front telescopic sliding hole 5. An anti-loosening telescopic groove 9 is opened inside the outer side of the rear end of the anti-loosening block 8, and an anti-loosening spring 10 is arranged inside the anti-loosening telescopic groove 9, and the anti-loosening spring 10 is located between the inner wall of the outer side of the rear end of the front telescopic sliding hole 5 and the inner wall of the front end of the anti-loosening telescopic groove 9. During the installation process of the pulling mechanism 4, when the pulling nut of the pulling mechanism 4 is tightened, the pulling nut presses the anti-loosening block 8 into the front telescopic sliding hole 5 until it can not be twisted. At this time, the anti-loosening block 8 always squeezes the pulling nut outward under the action of the anti-loosening spring 10 inside the anti-loosening telescopic groove 9, which can not only make the pulling nut more firmly fixed, but also prevent the pulling nut from loosening.

[0028] Preferably, the left and right sides of the rear end of the front telescopic slide hole 5 are connected with the rear telescopic slide hole 6, and the two rear telescopic slide holes 6 are opened inside the rear inner walls of the left and right ends of the pulling hole 3, the left and right rear sides of the front telescopic slide hole 5 are connected with the side slide grooves 7, and the two side slide grooves 7 are opened inside the connecting support mold strip 2, and are respectively connected with the two rear telescopic slide holes 6, the left and right rear sides of the anti-loosening block 8 are fixedly connected with the clamping block 11, and the two clamping blocks 11 are respectively slidably connected inside the two side slide grooves 7, the anti-loosening block 8 can be limited by the side slide grooves 7 and the clamping block 11 on both sides to prevent it from detaching from the front telescopic slide hole 5.

[0029] Preferably, the two rear telescopic sliding holes 6 are slidably connected with a clamping slider 12, and the front ends of the two clamping sliders 12 are provided with a clamping slot 13 inside the side away from the pulling hole 3. The two clamping abutments 11 are respectively located on the front ends of the two clamping slots 13 close to the pulling hole 3. The outer wall of the two clamping abutments 11 close to the pulling hole 3 and the inner wall of the two clamping slots 13 close to the pulling hole 3 are both inclined, and the two clamping abutments 11 can be slidably connected with the two clamping slots 13 through the inclined surfaces, and can slide smoothly into the clamping slots 13.

[0030] Preferably, a return groove 14 is provided inside the rear end of the clamping slide block 12 away from the side of the pulling hole 3, a return baffle 15 is provided inside the return groove 14 close to the pulling hole 3, and the return baffle 15 is fixedly connected to the inner wall of the rear telescopic slide hole 6, and a return expansion groove 16 is provided inside the center of the inner wall of the end of the return groove 14 away from the pulling hole 3, a return spring 17 is provided between the return expansion groove 16 and the return baffle 15, and the return spring 17 can be fully extended to the inside of the return expansion groove 16, During the removal of the tensioning mechanism 4, since the tensioning nut of the tensioning mechanism 4 no longer squeezes the anti-loosening block 8, the anti-loosening block 8 slides forward under the action of the anti-loosening spring 10, and makes the clamping block 11 slide out of the clamping slide groove 13. At this time, the clamping slider 12 slides to the side away from the tensioning hole 3 under the action of the return baffle 15 and the return telescopic groove 16, thereby sliding out of the tensioning hole 3 and contacting the clamping of the tensioning mechanism 4, so that the tensioning mechanism 4 can be smoothly taken out from the tensioning hole 3.
