Description

Technical Field

[0001] This utility model relates to the field of H-beam technology, specifically to a reinforcement structure for welding H-beams. Background Technology

[0002] H-beams are named for their parallel-flange design, where the flanges are parallel or nearly parallel on the inside and outside, and the flange ends form right angles. H-beams have a thinner web than ordinary I-beams of the same web height, but a wider flange, hence the name wide-flange I-beams. Due to their shape, H-beams have significantly better section modulus, moment of inertia, and corresponding strength than ordinary I-beams of the same weight. Used in metal structures with various requirements, H-beams demonstrate superior performance under bending moments, compressive loads, and eccentric loads, significantly increasing load-bearing capacity compared to ordinary I-beams and saving 10% to 40% of metal. The wide flanges, thin web, variety of specifications, and flexible application of H-beams allow for 15% to 20% metal savings in various truss structures. Because its flanges are parallel on the inside and outside and the flange ends are at right angles, it is easy to assemble into various components, thus saving about 25% of the welding and riveting work, which can greatly speed up the construction of the project and shorten the construction period; due to the above advantages, H-beams are widely used. However, the traditional splicing and assembly of H-beams is usually done by welding. In actual use, the welded joints of H-beams are prone to separation under stress, resulting in low stability of H-beams during use.

[0003] To address the aforementioned issues, this application proposes a reinforced structure for welding H-beams. Utility Model Content

[0004] This utility model aims to provide a reinforcement structure for welding H-beams, mainly to solve the problem that the splicing and assembly of traditional H-beam components is usually done by welding. In actual use, the welded joints of H-beam components are prone to separation under stress, resulting in low stability of H-beams during use.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A reinforced structure for welding H-beams includes an H-beam body, with positioning plates at each joint of the H-beam body. Fixing blocks are fixedly connected to both sides of the bottom of the inner wall of each positioning plate. A cavity is formed inside each fixing block, and symmetrical insert rods are slidably connected through and on each fixing block. One end of each insert rod extends out of the positioning plate. A drive assembly for synchronously sliding the two insert rods is provided inside the cavity. Slots matching the insert rods are formed on the inner wall of the H-beam body.

[0006] The working principle and beneficial effects of this utility model: 1. Working principle: After the two H-beams are welded, the positioning plate is clamped at the connection of the two H-beam bodies. By operating the drive component, the two insert rods located in the cavities of the fixed blocks on both sides are driven to move synchronously towards the inner wall of the H-beam body. The ends of the insert rods are finally inserted into the preset slots on the H-beam body, thereby firmly locking the positioning plate and the H-beam together to form a strong reinforcement node.

[0007] 2. Beneficial effects: By controlling the insertion of the plug rod into the slot through the drive component, the transformation from "external clamping" to "internal locking" is realized. The fixing force is much greater than that of ordinary clamps, which can effectively prevent deformation and misalignment at the weld of H-beam. Moreover, the drive component ensures that the plug rods on both sides move synchronously, so that the positioning plate is subjected to balanced force, avoiding the uneven load and inaccurate positioning that may be caused by unilateral locking, thus making the H-beam more stable during use.

[0008] Preferably, the bottom of the positioning plate is fixedly connected with symmetrical positioning posts, and the inner wall of the H-beam body is provided with positioning grooves that match the positioning posts. When the positioning plate is installed on the H-beam, the positioning posts are first aligned and inserted into the positioning grooves on the H-beam. This structure plays a "coarse positioning" role, which can quickly guide the positioning plate to the correct position, laying the foundation for the subsequent insertion rod to be accurately aligned with the slot, greatly improving the installation efficiency and centering accuracy. Moreover, after the positioning posts are inserted into the positioning grooves, they can withstand a certain shear force, further enhancing the stability of the connection node.

[0009] Preferably, a first magnet that attracts the positioning post is fixedly connected inside the positioning groove, and the first magnet is embedded in the positioning groove. When the positioning post (made of steel) approaches the positioning groove, it will be attracted by the first magnet. The magnetic force can generate a slight attraction force, making it difficult for the positioning post to fall out after it is fully inserted. It plays a temporary fixing role before final locking, which is particularly suitable for scenarios such as high-altitude operations where it is inconvenient to operate with both hands, thus improving safety and convenience.

[0010] Preferably, the corners of the inner wall of the positioning groove at the opening are all chamfered, forming a flared mouth. This allows the positioning post to be easily guided into the positioning groove even if there is a slight centering error, reducing the installation difficulty and improving the fault tolerance and installation efficiency.

[0011] Preferably, the inner wall of the positioning plate is fixedly connected with symmetrical reinforcing plates, and the reinforcing plates are triangular in shape, as the triangular structure has extremely high stability. The reinforcing plates can significantly enhance the rigidity and strength of the positioning plate itself, preventing it from bending or deforming when subjected to locking forces and welding stresses, thus ensuring the long-lasting and reliable reinforcement effect.

[0012] Preferably, the driving assembly includes a first bevel gear rotatably connected to the top of the inner wall of the cavity. A rotating rod is fixedly connected to the shaft at the top of the first bevel gear. A fixed block extends from the upper end of the rotating rod and is slidably connected to a knob. Symmetrical sliders are fixedly connected to the upper end of the outer wall of the rotating rod. A groove matching the slider is opened on the inner wall of the knob. A limiting component is provided at the bottom of the knob to prevent accidental rotation. Second bevel gears are provided on both sides of the first bevel gear inside the cavity. The second bevel gears mesh with the first bevel gear. A threaded rod is fixedly connected to the shaft on one side of each second bevel gear. The other end of each threaded rod extends into the interior of the insertion rod and is threadedly connected to the insertion rod. A fixing frame is fixedly connected to the bottom of the inner wall of the cavity on one side of the second bevel gear. The threaded rod passes through the fixing frame and is rotatably connected to it. Rotating the knob drives the rotating rod and the first bevel gear to rotate. The first bevel gear simultaneously drives the second bevel gears on both sides to rotate in opposite directions, thereby driving the two threaded rods to rotate synchronously. Since the insertion rod and the threaded rod are threadedly connected, the rotational motion is converted into the linear motion of the insertion rod, achieving synchronous extension or retraction.

[0013] Preferably, the limiting assembly includes multiple limiting posts fixedly connected to the bottom of the knob, and multiple limiting grooves matching the limiting posts are opened on the top of the fixing block. A second magnet that attracts the limiting posts is fixedly connected inside the limiting groove. When the knob is rotated to a specific position (such as when the plug is fully extended or retracted), pressing the knob causes the limiting post at its bottom to be inserted into the limiting groove. At the same time, the second magnet in the limiting groove will attract the limiting post. This can effectively prevent the knob from rotating under vibration or accidental collision, which would cause the plug to loosen, and greatly improve the reliability and safety of the entire locking mechanism.

[0016] 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.

[0017] Please see Figure 1-5 A reinforcement structure for welding H-beams includes an H-beam body 1. Positioning plates 2 are provided at the joints of the H-beam bodies 1. After two H-beams are welded, the positioning plates 2 are clamped at the joints of the two butt-jointed H-beam bodies 1, which can improve the stability of the H-beams after the connection. Fixing blocks 3 are fixedly connected to both sides of the bottom of the inner wall of the positioning plate 2. The fixing blocks 3 have cavities 4 inside. Symmetrical insert rods 5 are slidably connected through the fixing blocks 3. One end of the insert rods 5 extends out of the positioning plate 2. The cavity 4 is provided with a drive assembly for the two insert rods 5 to slide synchronously. The inner wall of the H-beam body 1 has slots 6 that match the insert rods 5. By operating the drive assembly, the two insert rods 5 located in the cavities 4 of the fixing blocks 3 on both sides are driven to move synchronously towards the inner wall of the H-beam body 1. The ends of the insert rods 5 are finally inserted into the preset slots 6 on the H-beam body 1, thereby firmly locking the positioning plate 2 and the H-beam together to form a strong reinforcement node. More specifically, the bottom of the positioning plate 2 is fixedly connected with symmetrical positioning posts 7. The inner wall of the H-beam body 1 is provided with a positioning groove 8 that matches the positioning post 7. The inside of the positioning groove 8 is fixedly connected with a first magnet 9 that attracts the positioning post 7. When the positioning plate 2 is installed on the H-beam, the positioning post 7 is first aligned and inserted into the positioning groove 8 on the H-beam. When the positioning post 7 (made of steel) approaches the positioning groove 8, it will be attracted by the first magnet 9. The magnetic force can generate a slight attraction force, making it difficult for the positioning post 7 to fall out after it is fully inserted. This structure plays a "coarse positioning" role, which can quickly guide the positioning plate 2 to the correct position, laying the foundation for the subsequent insertion rod 5 to be accurately aligned with the slot 6, greatly improving the installation efficiency and centering accuracy. Moreover, after the positioning post 7 is inserted into the positioning groove 8, it can withstand a certain shear force, further enhancing the stability of the connection node.

[0018] More specifically, the corners of the inner wall of the positioning groove 8 at the opening are all chamfered, forming a flared mouth. This allows the positioning post 7 to be easily guided into the positioning groove 8 even if there is a slight centering error, reducing the installation difficulty and improving the fault tolerance and installation efficiency.

[0019] More specifically, the inner wall of the positioning plate 2 is fixedly connected with symmetrical reinforcing plates 20, and the reinforcing plates 20 are triangular in shape. The triangular structure has extremely high stability. The reinforcing plates 20 can significantly enhance the rigidity and strength of the positioning plate 2 itself, preventing it from bending or deforming when subjected to locking force and welding stress, and ensuring the long-lasting and reliable reinforcement effect.

[0020] More specifically, the drive assembly includes a first bevel gear 14 rotatably connected to the top of the inner wall of the cavity 4. A rotating rod 10 is fixedly connected to the shaft at the top of the first bevel gear 14. A fixed block 3 extends from the upper end of the rotating rod 10 and is slidably connected to a knob 11. A symmetrical slider 12 is fixedly connected to the upper end of the outer wall of the rotating rod 10. A groove 13 matching the slider 12 is opened on the inner wall of the knob 11. A limiting component is provided at the bottom of the knob 11 to prevent it from turning accidentally. A second bevel gear 15 is provided on both sides of the first bevel gear 14 inside the cavity 4. The second bevel gear 15 meshes with the first bevel gear 14. A threaded rod 16 is fixedly connected to the shaft on one side of the second bevel gear 15. The other end of the threaded rod 16 extends into the interior of the insertion rod 5 and is threadedly connected to the insertion rod 5. A fixing frame 21 is fixedly connected to the bottom of the inner wall of the cavity 4 on one side of the second bevel gear 15. The threaded rod 16 passes through the fixing frame 21 and is rotatably connected to it. Rotating knob 11 causes the rotating rod 10 and the first bevel gear 14 to rotate. The first bevel gear 14 simultaneously drives the second bevel gears 15 on both sides to rotate in the opposite direction, thereby causing the two threaded rods 16 to rotate synchronously. Since the insertion rod 5 and the threaded rod 16 are threadedly connected, and the cross-section of the insertion rod 5 is rectangular, the insertion rod 5 can only move linearly inside the fixed block 3 and cannot rotate. This ensures that the rotational motion of the threaded rod 16 can be converted into the linear motion of the insertion rod 5, thereby achieving synchronous extension or retraction.

[0021] More specifically, the limiting assembly includes multiple limiting posts 17 fixedly connected to the bottom of the knob 11. The top of the fixing block 3 has multiple limiting grooves 18 that match the limiting posts 17. A second magnet 19 that attracts the limiting posts 17 is fixedly connected inside the limiting groove 18. When the knob 11 is rotated to a specific position (such as when the insertion rod 5 is fully extended or retracted), pressing the knob 11 causes the limiting posts 17 at its bottom to be inserted into the limiting grooves 18. At the same time, the second magnet 19 inside the limiting grooves 18 will attract the limiting posts 17. This effectively prevents the knob 11 from rotating under vibration or accidental collision, which would cause the insertion rod 5 to loosen. This greatly improves the reliability and safety of the entire locking mechanism.

[0022] As can be seen from the above, the specific embodiments of this utility model are as follows: After the two H-beams are welded, the positioning pin 7 is aligned and inserted into the positioning groove 8 on the H-beam. When the positioning pin 7 (made of steel) approaches the positioning groove 8, it will be attracted by the first magnet 9. The magnetic force can generate a slight attraction force, making it difficult for the positioning pin 7 to come out after it is fully inserted. Thus, the positioning plate 2 is locked at the connection of the two H-beam bodies 1. At this time, the knob 11 is turned to drive the rotating rod 10 and the first bevel gear 14 to rotate. The first bevel gear 14 simultaneously drives the second bevel gears 15 on both sides to rotate in the opposite direction, thereby driving the two threaded rods 16 to rotate synchronously. Since the insertion rod 5 and the threaded rod 16 are connected by a thread, the rotational motion is converted into the linear motion of the insertion rod 5, achieving synchronous extension or retraction. When the knob 11 is rotated to a specific position (such as when the insertion rod 5 is fully extended or retracted), pressing the knob 11 causes the bottom limiting post 17 to insert into the limiting groove 18. At the same time, the second magnet 19 in the limiting groove 18 will attract the limiting post 17. This effectively prevents the knob 11 from rotating under vibration or accidental collision, which would cause the insertion rod 5 to loosen. This greatly improves the reliability and safety of the entire locking mechanism.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
