Technical Field
[0001] This utility model relates to the technical field of reinforcing cage lifting bars, and in particular to a novel reusable reinforcing cage lifting bar. Background Technology
[0002] Reinforcing cage hangers are a common construction tool, also known as reinforcing cage hangers or reinforcing cage support frames. During the construction of bored piles, hangers are used to connect the reinforcing cage and the casing, fixing the cage to the casing at the borehole opening. This serves two purposes: firstly, it transfers concentrated loads (such as impact forces during construction) to the casing or pile cap, enhancing structural stability; secondly, it prevents the reinforcing cage from sinking or shifting, ensuring pile positioning accuracy.
[0003] The lifting bars are usually welded to the connecting bars of the reinforcing cage. The connecting bars of the reinforcing cage are located within the over-grouting range of the bored pile. After the pile is completed, they will be removed to expose the connecting bars and lap them with the pile cap reinforcement. Traditional lifting bars usually need to be customized according to the depth of each pile, which has the disadvantages of high production cost, low reuse rate and poor environmental performance. Utility Model Content
[0004] To reduce the cost of using rebar cage lifting bars, this application provides a novel reusable rebar cage lifting bar.
[0005] This application provides a novel reusable reinforcing cage support bar, which adopts the following technical solution: A novel reusable steel cage lifting bar includes a load-bearing column, with a cylindrical part threadedly connected to the end of the load-bearing column away from the foundation. The cylindrical part has oppositely symmetrical lifting hooks on both sides, and the cylindrical part is provided with a fixing member for fixing the lifting hooks.
[0006] By adopting the above technical solution, in the actual construction process, the load-bearing column is fixed to the connecting bar of the steel cage through the hook. The connection between the hook and the steel cage is detachable, which facilitates the recycling of the hook and reduces the cost of using the hook to a certain extent.
[0007] Preferably, the end face of the hook that contacts the connecting rib is provided with a friction-enhancing part.
[0008] By adopting the above technical solution and setting the friction-enhancing part, the friction between the hook and the connecting bar of the steel cage is effectively increased, making it less likely for the hook to detach from the steel cage and ensuring the effectiveness of the lifting bar device.
[0009] Preferably, it also includes a crossbeam mounted on the support platform, the crossbeam having a through-hole for the load-bearing column to pass through, and the crossbeam having a positioning nut that is threaded into the load-bearing column, the positioning nut being located on the side of the crossbeam away from the hook.

The hook of different sizes can be adjusted according to the thickness of the connecting bar of the steel cage, thereby ensuring the reliability of fixing the steel cage by the lifting bar. In addition, it is also easy to replace the damaged hook, further saving the cost of using the lifting bar.
[0015] Preferably, the fastening part is provided with a countersunk hole for accommodating the head of the fixing bolt.
[0016] By adopting the above technical solution, the setting of the fixed countersunk hole can effectively protect the fixing bolt, thus facilitating the removal of the fixing bolt after long-term use to a certain extent.
[0017] Preferably, the fastening part is detachably connected to a sealing block for sealing the connection between the fixed countersunk hole and the outside. The sealing block is provided with a sealing ring, and the end of the sealing ring away from the sealing block abuts against the inner wall of the fixed countersunk hole.
[0018] By adopting the above technical solution and setting the sealing block, the service life of the fixing bolts is further guaranteed.

[0026] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.
[0027] Example 1: This application discloses a novel reusable reinforcing cage lifting bar, referring to... Figure 1 The embodiment includes a load-bearing column 1. In this application embodiment, the load-bearing column 1 is a precision-rolled threaded steel bar. The precision-rolled threaded steel bar is processed by precision rolling and special technology. The surface of the precision-rolled threaded steel bar forms a uniform thread, which not only improves the mechanical properties of the steel itself, but also enhances the synergistic effect with concrete. Its high strength, corrosion resistance and other characteristics make it perform well in complex engineering environments.
[0028] Reference Figure 1 and Figure 3It also includes a crossbeam 2 mounted on the support platform. The crossbeam 2 can be fixed to the support platform by welding to form a solid connection 21. The crossbeam 2 is provided with a load-bearing through hole 22 for the load-bearing column 1 to pass through. There are two solid connections 21 on the crossbeam 2, which are symmetrically arranged on both sides of the load-bearing through hole 22. The crossbeam 2 is provided with a positioning nut 23 that is threaded to the load-bearing column 1. The positioning nut 23 is located on the side of the crossbeam 2 away from the hook 4. The relative position between the load-bearing column 1 and the crossbeam 2 is determined by the positioning nut 23.
[0029] Reference Figure 1 and Figure 2 The end of the load-bearing column 1 furthest from the foundation is threadedly connected to a cylindrical part 3. The cylindrical part 3 has oppositely symmetrical hooks 4 on both sides. The cylindrical part 3 is equipped with a fixing component for securing the hooks 4. In this embodiment, the fixing component includes a connecting part 41 welded to the side of the cylindrical part 3. The connecting part 41 is welded to the hooks 4. Through the threaded connection between the cylindrical part 3 and the load-bearing column 1, in actual construction, one end of the load-bearing column 1 is fixed to the foundation by cooperating with the crossbeam 2 through a positioning nut 23, and the other end of the load-bearing column 1 is fixed to the connecting bar of the reinforcing cage through the hooks 4. The entire connecting bar is detachably connected to the foundation and the reinforcing cage, facilitating the recycling of the connecting bar and thus reducing the cost of using the connecting bar to a certain extent.
[0030] Reference Figure 2 and Figure 4 The end face of the hook 4 that contacts the connecting bar is provided with a friction-enhancing part 42. By setting the friction-enhancing part 42, the friction between the hook 4 and the connecting bar of the steel cage is effectively increased, making it difficult for the hook 4 to detach from the steel cage and ensuring the effectiveness of the lifting bar device.
[0031] The implementation principle of a reusable novel rebar cage lifting bar in this application embodiment is as follows: In actual application, the crossbeam 2 is first fixed on the bearing platform. Then, one end of the load-bearing column 1 is passed through the corresponding load-bearing through hole 22, and the cylinder part 3 is tightened on that end to complete the installation of the hook 4. Then, the operator needs to position the connecting bar from the bottom of the load-bearing column 1 to the rebar cage between the hooks 4 on both sides of the cylinder part 3. Then, the load-bearing column 1 is rotated so that the connecting bar of the rebar cage aligns with the friction-enhancing part 42 of the hook 4. The load-bearing column 1 is then lifted so that the connecting bar and the friction-enhancing part 42 are pressed together. Then, the positioning bolts are tightened to complete the installation of the lifting bar. When the bored pile is finished, the positioning nut 23 is removed, and the load-bearing column 1 is moved to the bottom of the connecting bar. Then, the load-bearing column 1 is rotated to release the engagement between the hook 4 and the connecting bar. Subsequently, the load-bearing column 1 can be lifted to complete the dismantling.
[0032] Example 2 differs from Example 1 in that, referring to... Figure 5The fasteners include a fastening part 5 welded to the hook 4, and a fixing part 51 corresponding to the fastening part 5 welded to the side of the cylindrical part 3. A fixing through hole 511 is provided through the fixing part 51. A fixing block 52 that mates with the fixing through hole 511 is provided on the side of the fastening part 5 facing the cylindrical part 3. The fixing block 52 is embedded in the fixing through hole 511. A fixing bolt 53 is provided on the cylindrical part 3, and a fixing threaded hole 531 that mates with the fixing bolt 53 is provided on the cylindrical part 3. The fastening part 5 and the fixing part 51... The fixing block 52 has a through hole 532 for the fixing bolt 53 to pass through. In the actual installation process, after the fixing part 51 is inserted into the fixing through hole 511, the hook 4 is fixed to the cylinder part 3 by bolts. This makes the hook 4 and the cylinder part 3 detachably connected. The hook 4 of different sizes can be adjusted according to the thickness of the connecting bar of the steel cage, thereby ensuring the reliability of fixing the steel cage by the lifting bar. In addition, it is easy to replace the damaged hook 4, further saving the cost of using the lifting bar.
[0033] Reference Figure 5 The fastening part 5 is provided with a countersunk hole 54 for accommodating the head of the fixing bolt 53. The countersunk hole 54 effectively protects the fixing bolt 53, thus facilitating its removal after long-term use. A sealing block 541 is detachably connected to the fastening part 5 to block the connection between the countersunk hole 54 and the outside. The sealing block 541 is provided with a sealing ring 542. The sealing block 541 with the sealing ring 542 is press-fitted with the countersunk hole 54. Therefore, the end of the sealing ring 542 away from the sealing block 541 abuts against the inner wall of the countersunk hole 54. The sealing block 541 further ensures the service life of the fixing bolt 53.
[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
