[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1 This utility model provides an embodiment of a steel strand mesh tensioning and fastening assembly for reinforcing building structures, comprising a support plate 1, a motor 2 fixedly connected to the outer wall of the support plate 1, the output end of the motor 2 penetrating the interior of the support plate 1 and fixedly mounted with a rotating arm 3, a fixing frame 4 fixedly connected to the outer wall of the rotating arm 3, a slider 5 slidably connected inside the fixing frame 4, a lead screw 6 threadedly connected inside the slider 5, the outer wall of the lead screw 6 rotatably connected to the interior of the fixing frame 4, a knob 7 fixedly connected to the top of the lead screw 6, a connecting rod 8 rotatably connected to the outer wall of the slider 5, a sliding groove 9 opened inside the support plate 1, a sliding frame 10 rotatably connected to the outer wall of the connecting rod 8, the outer wall of the sliding frame 10 slidably connected to the interior of the sliding groove 9, and a connecting assembly provided on the outer wall of the sliding frame 10 for connecting the steel strand mesh to be stretched.
[0026] Specifically, the support plate 1 can fix and support the motor 2. Starting the motor 2 drives the rotating arm 3 to rotate, and the rotating arm 3 drives the fixed frame 4 on the outer wall to rotate. The outer wall of the slider 5 is connected to the inside of the fixed frame 4. The rotation of the fixed frame 4 will drive the slider 5 to rotate. The slider 5 drives the sliding frame 10 to slide through the connecting rod 8. The outer wall of the support plate 1 has a sliding groove 9. The outer wall of the sliding frame 10 slides inside the sliding groove 9. The sliding groove 9 restricts the sliding direction of the sliding frame 10. The sliding distance of the sliding frame 10 can be adjusted by rotating the knob 7. Rotating the knob 7 drives the lead screw 6 to rotate. The inside of the fixed frame 4 has a sliding groove. The lead screw 6 drives the slider 5 to slide in the sliding groove of the fixed frame 4. When the slider 5 rises and slides, the sliding distance of the sliding frame 10 will become longer. When the slider 5 falls and approaches the output end of the motor 2, the sliding distance of the sliding frame 10 will become shorter. For steel strands that do not need to be stretched too long, it is easier to control precisely.
[0027] Reference Figure 1 The connecting assembly includes a connecting rod 11, one end of which is fixedly connected to the outer wall of the sliding frame 10, and the other end of which is fixedly connected to a connecting ring 12.
[0028] Specifically, the steel strand mesh to be tensioned can be connected to the connecting ring 12 first. When the sliding frame 10 slides, the sliding frame 10 transmits tension to the connecting ring 12 through the connecting rod 11, thereby tensioning the steel strand mesh.
[0029] Reference Figure 1 and Figure 2 The outer wall of the support plate 1 is provided with a fixing plate 13, and the front outer wall of the fixing plate 13 is provided with a mounting plate 14; the outer wall of the mounting plate 14 is rotatably connected with a positive and negative threaded rod 15, the outer wall of the positive and negative threaded rod 15 is threadedly connected with a fixing ring 16, the inner side of the fixing ring 16 is slidably connected with a slide rod 17, and the outer wall of the slide rod 17 is fixedly connected to the outer wall of the mounting plate 14.
[0030] Specifically, the tensioned steel strand mesh can be placed between the two fixing rings 16. By rotating the positive and negative screws 15, the two fixing rings 16 are driven to slide towards the center, and the sliding rod 17 supports the sliding of the fixing rings 16, thereby connecting the steel strand mesh to the mounting plate 14.
[0031] Reference Figures 2-4A button 18 is slidably connected inside the mounting plate 14. A first limiting pin 19 is fixedly connected to the outer wall of the button 18. A telescopic rod 20 is fixedly connected to the outer wall of the first limiting pin 19. A second limiting pin 22 is fixedly connected to the outer wall of the telescopic rod 20. The outer wall of the second limiting pin 22 is fixedly connected to the outer wall of the button 18. The front outer walls of both the second limiting pin 22 and the first limiting pin 19 are slidably connected inside the mounting plate 14. A spring 21 is fixedly connected to the outer wall of the first limiting pin 19. The spring 21 is located outside the telescopic rod 20. The outer wall of the spring 21 is fixedly connected to the outer wall of the second limiting pin 22. A limiting groove 23 is formed inside the fixing plate 13. The rear outer walls of both the first limiting pin 19 and the spring 21 are located inside the limiting groove 23.
[0032] Specifically, buttons 18 are slidably connected to both sides of the mounting plate 14. Buttons 18 are also connected to the first limiting pin 19 and the second limiting pin 22. When the mounting plate 14 is installed, the second limiting pin 22 and the first limiting pin 19 are inserted into the fixing plate 13. The tips of the second limiting pin 22 and the first limiting pin 19 slide against the fixing plate 13, thereby squeezing the second limiting pin 22 and the first limiting pin 19 to slide in the center. At this time, the telescopic rod 20 retracts and the spring 21 is compressed. When the first limiting pin 19 and the second limiting pin 22 are fully inserted into the fixing plate 13, the spring 21 rebounds, and the first limiting pin 19 and the second limiting pin 22 are fixed to the fixing plate 13. When disassembly is required, the buttons 18 are pressed actively in the center. At this time, the first limiting pin 19 and the second limiting pin 22 can be pulled out.
[0033] Working principle: When using this structure, first connect the steel strand mesh to the connecting ring 12. The sliding frame 10 transmits tension to the connecting ring 12 through the connecting rod 11. The starting motor 2 drives the rotating arm 3 at the output end to rotate. The fixed frame 4 is fixed to the outer wall of the rotating arm 3. The rotation of the rotating arm 3 drives the fixed frame 4 to rotate. The rotation of the fixed frame 4 drives one end of the lead screw 6 to rotate through the slider 5. The other end of the lead screw 6 drives the sliding frame 10 to slide. The sliding frame 10 slides inside the slide groove 9. The slide groove 9 restricts the sliding of the sliding frame 10. The sliding of the sliding frame 10 will pull the steel strand to stretch. When the knob 7 is turned, the knob 7 drives the lead screw 6 to rotate. The lead screw 6 drives the slider 5 to slide inside the fixed frame 4. After the slider 5 slides, the starting motor 2 drives the rotating arm 3 to rotate. At this time, the distance that the sliding frame 10 can slide will change. When connecting... When installing plate 14 and fixing plate 13, insert the first limiting pin 19 and the second limiting pin 22 into the fixing plate 13. The first limiting pin 19 and the second limiting pin 22 will be squeezed and converge towards the center. Then, the spring 21 rebounds and locks the tips of the second limiting pin 22 and the first limiting pin 19 into the fixing plate 13. The stretched steel strand is placed into the fixing ring 16. The steel strand is clamped by rotating the positive and negative screws 15, thus completing the fixing of the steel strand and the mounting plate 14 together. When it is necessary to remove the mounting plate 14, press the button 18 to slide the second limiting pin 22 and the first limiting pin 19 towards the center. At this time, the first limiting pin 19 and the second limiting pin 22 can be pulled out. This structure can adjust the sliding distance of the sliding frame 10 to accommodate a longer stretching distance, and also facilitates the installation and removal of the mounting plate 14, improving work efficiency.
