Description

Technical Field

[0001] This utility model relates to the field of steel structure building construction technology, and in particular to a quick-connect locking device for vertical outer ribs of steel structure beams and columns. Background Technology

[0002] Vertical outer ribs for steel structure beams and columns are reinforcing components welded or assembled to the outside of the joint between steel structure beams and columns. Their core purpose is to enhance the structural strength, stiffness, and stability of the vertical connection between beams and columns, distribute the stress at the connection, and prevent deformation or breakage due to load during long-term use. Because precise alignment and rapid fixing are required for beam-column connections during steel structure construction, a rapid connection and locking device for vertical outer ribs of steel structure beams and columns is necessary. The quick-connect locking device for vertical outer ribs of steel structure beams and columns is a special tooling for connecting steel structure beams and columns with vertical outer ribs. It can quickly achieve component positioning and initial fixation through mechanical structure. Previous connection devices mostly lacked efficient initial fixation function and relied on manual support for alignment, which was not only time-consuming and labor-intensive, but also prone to hole misalignment due to human shaking, reducing the overall connection efficiency and accuracy. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a quick-connect locking device for the vertical outer ribs of steel structure beams and columns, which aims to improve the problem of lacking efficient initial fixing function and relying on manual support for alignment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect locking device for vertical outer ribs of steel structure beams and columns, comprising a steel column and a steel beam. The outer wall of the steel column is fitted with the outer wall of the steel beam. The interior of the steel column is provided with a pin hole and a slot. A cylinder is fixedly connected to the outer wall of the steel beam. A connecting component is provided on the inner wall of the cylinder. A limiting cylinder is fixedly connected to the outer wall of the connecting component. The outer wall of the limiting cylinder is fixedly connected to the inner wall of the cylinder. A round-headed block is slidably connected to the inner wall of the limiting cylinder. The outer wall of the round-headed block is slidably connected through the interior of the cylinder. A spring is provided inside the limiting cylinder. One end of the spring is fixedly connected to the inner wall of the limiting cylinder, and the other end of the spring is fixedly connected to the outer wall of the round-headed block. The outer wall of the round-headed block is slidably connected to the inner walls of the pin hole and the slot.

[0005] Preferably, the connecting assembly includes a connecting column, both ends of which are fixedly connected to the inner wall of the cylinder, and a connecting plate is fixedly connected through the outer wall of the connecting column. The lower surface of the limiting cylinder is fixedly connected to the outer wall of the connecting plate.

[0006] Preferably, a magnet is fixedly connected inside the steel column, and an iron block is fixedly connected inside the steel beam.

[0007] Preferably, the outer wall of the steel beam is provided with reinforcing ribs, and the outer wall of the reinforcing ribs is in contact with the outer wall of the steel column.

[0008] Preferably, the reinforcing rib has a pre-drilled hole one inside, and the steel column has a pre-drilled hole two inside.

[0009] Preferably, bolts are slidably connected inside both the first and second reserved holes, and a washer is provided through the outer wall of the bolt.

[0010] Preferably, the outer wall of the gasket fits into the outer wall of the reinforcing rib, and the outer wall of the bolt is threaded with a thin nut and a thick nut respectively.

[0011] Preferably, the outer wall of the thin nut is in contact with the outer wall of the washer, and the outer wall of the thin nut is in contact with the outer wall of the thick nut.

[0012] This utility model has the following beneficial effects: 1. In this utility model, by pushing the cylinder into the pin hole, the round head block is continuously squeezed during the pushing process, causing it to slide smoothly inside the cylinder, the inner wall of the limiting cylinder, and the inner wall of the pin hole. During the sliding process, the round head block drives the spring to compress and store elastic potential energy. As the cylinder continues to go deeper, the round head block slides along the inner wall of the pin hole to align with the slot. When the round head block slides into the slot, the spring reaction force is quickly released, causing the round head block to reset and lock firmly, thereby playing a role in quickly and initially fixing the steel column and steel beam, effectively limiting the relative displacement between the two, and achieving the effect of establishing a precise benchmark for subsequent final fixing, thus improving the overall docking efficiency and accuracy.

[0013] 2. In this utility model, by placing the reinforcing rib on the steel beam and positioning the reinforcing rib by the mutual attraction between the magnet and the iron block, the first and second pre-reserved holes are ensured to correspond. Then, the bolt is passed through the two pre-reserved holes, the washer is installed, and the thin nut is screwed into the connecting column so that the washer fits against the thin nut. The thin nut drives the washer to press the reinforcing rib. After tightening the thin nut, the thick nut is tightened and fitted against the thin nut. This method achieves the functions of precise positioning and double locking of the steel structure beam-column joint, achieving the effects of quickly completing the joint assembly, enhancing the structural strength of the connection, preventing the nut from loosening, and ensuring the long-term stability of the connection.

[0016] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a quick-connect locking device for vertical outer ribs of steel structure beams and columns, including a steel column 1 and a steel beam 2. The outer wall of the steel column 1 is in contact with the outer wall of the steel beam 2. The steel column 1 is provided with a pin hole 3 and a slot 4. The outer wall of the steel beam 2 is fixedly connected to a cylinder 5. The inner wall of the cylinder 5 is provided with a connecting component. The outer wall of the connecting component is fixedly connected to a limiting cylinder 8. The outer wall of the limiting cylinder 8 is fixedly connected to the inner wall of the cylinder 5. The inner wall of the limiting cylinder 8 is slidably connected to a round head block 9. The outer wall of the round head block 9 is slidably connected through the inside of the cylinder 5. The inside of the limiting cylinder 8 is provided with a spring 10. One end of the spring 10 is fixedly connected to the inner wall of the limiting cylinder 8, and the other end of the spring 10 is fixedly connected to the outer wall of the round head block 9. The outer wall of the round head block 9 is slidably connected to the inner walls of the pin hole 3 and the slot 4. Specifically, the steel column 1 and steel beam 2, when fitted together, serve as the foundation for the steel structure frame, providing a fitting carrier for subsequent docking and locking, thus ensuring the stability of the structural connection. The pin hole 3 guides the insertion of the cylinder 5, allowing for precise positioning and installation, and provides a channel for the sliding of the round head block 9, achieving the effect of auxiliary component positioning and docking. The slot 4 engages with the round head block 9, providing a fixing point for it, achieving the initial fixation of the steel column 1 and steel beam 2. The cylinder 5 supports the connecting components, the limiting cylinder 8, and the round head block 9, driving the internal components to insert into the pin hole 3. The locking force is transmitted effectively. The limiting cylinder 8 guides the round head block 9 to slide and accommodates the spring 10, limiting the sliding trajectory of the round head block 9 and preventing deviation. This ensures the precise engagement of the round head block 9. The spring 10 provides elastic restoring force. After being compressed by the round head block 9, it releases its elastic force, causing the round head block 9 to reset and engage in the slot 4, achieving the effect of automatic initial locking. The round head block 9 transmits the elastic force of the spring 10 and engages in the fixing process. When sliding, it compresses the spring 10, and when resetting, it engages in the slot 4, causing the steel column 1 and steel beam 2 to be initially locked, thus establishing a precise benchmark for final fixing.

[0018] Reference Figure 3 The connecting assembly includes a connecting post 6, both ends of which are fixedly connected to the inner wall of the cylinder 5. A connecting plate 7 is fixedly connected through the outer wall of the connecting post 6, and the lower surface of the limiting cylinder 8 is fixedly connected to the outer wall of the connecting plate 7. Specifically, the connecting column 6 and connecting plate 7 of the connecting component work together to fix the limiting cylinder 8, and securely install the limiting cylinder 8 inside the cylinder 5, thus ensuring the stable installation of the limiting cylinder 8 and the round head block 9.

[0019] Reference Figure 1 , Figure 4 and Figure 5 A magnet 14 is fixedly connected inside the steel column 1, and an iron block 15 is fixedly connected inside the steel beam 2; a reinforcing rib 11 is provided on the outer wall of the steel beam 2, and the outer wall of the reinforcing rib 11 is in contact with the outer wall of the steel column 1; a reserved hole 12 is opened inside the reinforcing rib 11, and a reserved hole 23 is opened inside the steel column 1. Specifically, the magnet 14 and the iron block 15 attract each other, which helps to precisely position the reinforcing rib 11, allowing it to fit against the connection between the steel column 1 and the steel beam 2. This ensures that the first reserved hole 12 and the second reserved hole 13 are aligned, simplifying the positioning operation and ensuring accurate hole correspondence. The reinforcing rib 11 enhances the structural strength of the connection between the steel column 1 and the steel beam 2, distributing the stress at the connection and improving the load-bearing capacity of the connection. The first reserved hole 12 and the second reserved hole 13 guide the bolt 16 through, providing an installation channel for the bolt 16 and facilitating its precise assembly. The bolt 16 penetrates and fixes the steel column 1 and the reinforcing rib 11, connecting the components to form a stable connection and strengthening the locking effect. The washer 17 disperses the pressure of the nut, fitting against the reinforcing rib 11 and the thin nut 18, preventing damage to the component surface when the nut is tightened, thus protecting the component and enhancing the connection sealing.

[0020] Reference Figure 1 , Figure 4 and Figure 5 Both reserved holes 12 and 13 are slidably connected with bolts 16, and a washer 17 is provided through the outer wall of the bolt 16. The outer wall of the washer 17 fits against the outer wall of the reinforcing rib 11. A thin nut 18 and a thick nut 19 are threadedly connected to the outer wall of the bolt 16 respectively. The outer wall of the thin nut 18 fits against the outer wall of the washer 17, and the outer wall of the thin nut 18 fits against the outer wall of the thick nut 19. Specifically, the thin nut 18 serves as a preliminary locking mechanism. When tightened, it causes the washer 17 to press against the reinforcing rib 11, thus achieving the effect of initially fixing the various mating components. The thick nut 18 and the thin nut 19 fit together and are tightened to achieve a double locking effect. They fit together to form an anti-loosening fit, which prevents the nuts from loosening due to vibration and ensures the long-term stability of the connection. Together with the initial fixing structure, it completes the rapid mating and locking of the steel structure beams and columns.

[0021] Working principle: When the device is needed, first push the cylinder 5 into the pin hole 3, and then squeeze the round head block 9, so that it slides inside the cylinder 5 and the inner wall of the limiting cylinder 8 respectively. At the same time, the round head block 9 also slides inside the pin hole 3. The round head block 9 drives the spring 10 to be compressed. When the round head block 9 slides into the slot 4, under the reaction force of the spring 10, the round head block 9 is driven to reset and lock into the slot 4, thus playing the role of initial fixation of the steel column 1 and the steel beam 2, achieving the effect of establishing a benchmark for final fixation. Then, the reinforcing rib 11 is placed on the steel beam 2. The reinforcing rib 11 is positioned by the mutual attraction between the magnet 14 and the iron block 15, ensuring that the reserved hole 12 and the reserved hole 2 13 correspond. Then, the bolt 16 is passed through the reserved hole 12 and the reserved hole 2 13, and the washer 17 is passed through the outer wall of the bolt 16. Then, the thin nut 18 is screwed into the connecting column 6, so that the washer 17 and the thin nut 18 fit together. The thin nut 18 drives the washer 17 to fit together with the reinforcing rib 11. After tightening the thin nut 18, the thick nut 19 is tightened and made to fit together with the thin nut 18. The effect of the thin nut 18 and the thick nut 19 fitting together and tightening together achieves the effect of preventing the thin nut 18 and the thick nut 19 from loosening due to shaking.
