Description

Technical Field

[0001] This invention relates to the field of building technology, specifically to a tie rod for assembling aluminum formwork for easy loading and unloading. Background Technology

[0002] Tie rods are a type of fixing device commonly used in the middle stage of building aluminum formwork. The common method is to fix the tie rods to the aluminum formwork. The surface of the aluminum formwork is grooved, one end of the tie rod is inserted into the groove and then fixed by fasteners. When disassembling later, the aluminum formwork is first disassembled, then the tie rods are broken off, and the remaining tie rods are stored inside the concrete.

[0003] However, traditional tie rods need to be broken after disassembly, and the broken ends are prone to water seepage. The breaking process is also quite troublesome, which reduces work efficiency. In addition, the tie rods connected to the aluminum template cannot be reused after each processing, resulting in resource waste. Therefore, a new tie rod is needed that can be quickly disassembled and reused multiple times. Summary of the Invention

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figure 1-4As shown, the present invention provides a technical solution: a tie rod for easy loading and unloading of building aluminum formwork assembly, comprising a plate body 1, a storage groove 5 inside the plate body 1, a double-threaded sleeve 2 rotatably connected inside the plate body 1, threaded rods 3 on both sides of the double-threaded sleeve 2, an adjustment groove 4 symmetrically opened on the upper surface of the plate body 1, a sleeve plate 7 slidably connected inside the adjustment groove 4 via a connecting block 6, a first gear 8 rotatably connected inside the storage groove 5, the first gear 8 meshing with the double-threaded sleeve 2, a first rack 9 slidably connected inside the storage groove 5, the first rack 9 being fixedly connected to the sleeve plate 7, the threaded rods 3 being rotatably connected to the connecting block 6, and guide plates 10 symmetrically detachably connected to opposite sides of the sleeve plate 7, the two sides of the plate body 1... Each side is provided with a fixing plate 11. A guide groove 12 is symmetrically opened on the left side of the fixing plate 11. A winding groove 13 is opened inside the fixing plate 11. The guide groove 12 and the winding groove 13 are connected. A winding rod 14 is rotatably connected inside the winding groove 13. A second gear 15 is fixedly connected to the middle of the outer side wall of the winding rod 14. A return spring 16 is fixedly connected to the inner wall of the winding groove 13. A second rack 17 is meshed with the outer side wall of the second gear 15. The return spring 16 and the second rack 17 are fixedly connected. An insertion rod 18 is fixedly connected to the outer end of the guide plate 10. The insertion rod 18 is adapted to the second rack 17. A winding rope 19 is wound around the outer side wall of the winding rod 14. An electromagnetic groove 20 is opened inside the fixing plate 11. An internal circuit board 21 is fixedly connected. An electromagnetic block 22 is provided inside the electromagnetic groove 20. A pulley body 23 is fixedly connected to the corner of the electromagnetic block 22. The pulley body 23 is slidably connected to the circuit board 21. Rotating blocks 24 are fixedly connected to the upper and lower surfaces of the guide plate 10. A limit plate 25 is rotatably connected inside the rotating block 24. An electromagnetic ball 26 is rotatably connected inside the limit plate 25. The electromagnetic ball 26 is electromagnetically connected to the electromagnetic block 22. In use, by pulling the collar 7, the first rack 9 is moved. Since the first rack 9 is meshed with the first gear 8, and the first gear 8 is meshed with the double-threaded sleeve 2, the double-threaded sleeve 2 is rotated. Since both ends of the double-threaded sleeve 2 are threadedly connected to screws... The threaded rod 3 is rotatably connected to the connecting block 6. The connecting block 6 and the adjusting groove 4 are engaged, so the sleeve plate 7 and the threaded rod 3 move synchronously to form a more stable support. Then the guide plate 10 and the sleeve plate 7 are disassembled by threads. After the guide plate 10 is installed, the fixing plate 11 is fixed in the middle of the aluminum template. Then the guide plate 10 is inserted into the fixing plate 11. The insert rod 18 in the guide plate 10 contacts the second rack 17, so that it squeezes the return spring 16, and then drives the second gear 15 to rotate, so that the winding rod 14 rotates, and then the winding rope 19 is wound up, which drives the electromagnetic block 22 to move in the circuit board 21. And due to the electromagnetic adsorption of the electromagnetic block 22 and the electromagnetic ball 26, the limiting plate 25 is unfolded and fixed.

[0025] Furthermore, each of the opposite sides of the fixing plate 11 is integrally formed with a plug-in plate 27. The upper and lower surfaces of the plug-in plate 27 are provided with positioning grooves 28. Positioning blocks 29 are slidably connected inside the positioning grooves 28. Locking springs 30 are fixedly connected to the opposite sides of the positioning blocks 29. The upper surface of the fixing plate 11 is provided with a control groove 31. A control rod 32 is rotatably connected inside the control groove 31. A third gear 33 is fixedly connected to the outer wall of the control rod 32. A control rope 34 is wound around the outer wall of the control rod 32. The control rope 34 is a three-headed rope. The two ends of the control rope 34 are respectively fixedly connected to the opposite sides of the two positioning blocks 29. Next, a slide plate 35 is fixedly connected inside the control groove 31. A slide bar 36 is slidably connected to the right side of the slide plate 35. The slide bar 36 is meshed with the third gear 33. A pressing rod 37 is slidably connected inside the control groove 31. The pressing rod 37 is fixedly connected to the slide bar 36. When the pressing rod 37 moves downward, it moves the slide bar 36 and meshes with the third gear 33, causing the control rod 32 to rotate. This causes the control rope 34 to wind up. The control rope 34 pulls the two positioning blocks 29 relative to each other, causing the positioning blocks 29 to retract into the positioning groove 28. This allows the plug-in plate 27 to be quickly inserted into the aluminum template to form a fixed installation, and it is easy to disassemble.

[0026] Furthermore, a top spring 38 is fixedly connected to the lower inner surface of the control groove 31. The top spring 38 is fixedly connected to the slide bar 36 to reset the slide bar 36.

[0027] Furthermore, a sealing ring 39 is fixedly connected to the outer wall of the sleeve 7, which forms a waterproof performance during the later fixing process.

[0028] Furthermore, the double-threaded sleeve 2 is threadedly connected to the threaded rod 3, which facilitates disassembly and installation and allows for multiple uses.

[0029] Furthermore, electromagnetic induction can be generated between the electromagnetic block 22 and the electromagnetic ball 26, forming an adsorption stability.

[0030] In summary, the workflow of this invention is as follows: the pressing rod 37 moves downward, thereby moving the slide bar 36, which meshes with the third gear 33, driving the control rod 32 to rotate, causing the control rope 34 to wind up. The control rope 34 pulls the two positioning blocks 29 relative to each other, thereby retracting the positioning blocks 29 into the positioning groove 28. This allows the plug plate 27 to be quickly inserted into the aluminum template to form a fixed installation. Then, the guide plate 10 and the sleeve plate 7 are threaded together, and the guide plate 10 is inserted into the fixing piece 11. The insert rod 18 in the guide plate 10 contacts the second rack 17, causing it to press against the reset spring 16. This drives the second gear 15 to rotate, causing the winding rod 14 to rotate, thereby causing the winding rope 19 to wind up. This causes the electromagnetic block 22 to move within the circuit board 21. Due to the electromagnetic adsorption between the electromagnetic block 22 and the electromagnetic ball 26, the limiting plate 25 unfolds and is fixedly limited.
