Description

Technical Field

[0001] This utility model relates to the field of steel structure connection technology, and in particular to a quick connection component for steel structures. Background Technology

[0002] In the fields of building construction and steel structure construction, the connection between steel beams and columns is a crucial link in establishing the overall structural stability. With the development of prefabricated buildings and high-rise steel structures, higher requirements are placed on the installation efficiency, load-bearing capacity, and seismic and vibration resistance of connection nodes. Traditional connection methods mostly rely on bolts or welding, which are cumbersome to operate, difficult to meet the needs of rapid installation and repeated disassembly, and prone to loosening under vibration or dynamic loads, affecting structural safety.

[0003] Currently, some components for quick connection of steel structures are available on the market, which mainly use clamping structures to fix steel beams and columns. However, existing devices lack effective anti-loosening structures after clamping, making them prone to reduced clamping force or even loosening due to vibration or external forces. Furthermore, the alignment process between the clamping components and the steel beam is complex, requiring repeated manual adjustments, which affects installation efficiency. Therefore, there is an urgent need for a steel structure connection component that can achieve quick clamping, automatic alignment, and good anti-loosening performance to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-connect assembly for steel structures. This assembly achieves rapid clamping through a bidirectional lead screw and a slider clamping plate, and the screw is locked by a threaded rod driving the clamping block to prevent rotational failure. At the same time, the wedge block and wedge groove are automatically aligned, and the disc spring assembly provides preload, improving clamping stability and vibration resistance. The assembly is simple to operate, safe, and efficient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect assembly for steel structures, including a column, a support plate fixedly connected to the upper end of the column, a base fixedly connected to the upper end of the support plate, two side plates fixedly connected to the upper end of the base, a slider connected inside the base via a sliding assembly, a clamping plate fixedly connected to the upper end of the slider, a sliding rod slidably connected to the inner wall of the clamping plate, a disc spring assembly sleeved on the outer wall of the middle part of the sliding rod, a wedge block fixedly connected to one end of the sliding rod, a double-acting screw threadedly connected to the middle part of the slider, a handwheel fixedly connected to the right end of the double-acting screw, a lower clamping block provided on the inner wall of the left end of the base, an upper clamping block rotatably connected to the upper side of one end of the lower clamping block, a threaded rod threadedly connected to the other end of the lower clamping block, and a handle fixedly connected to the top end of the threaded rod.

[0006] Furthermore, the sliding assembly includes a sliding groove formed inside the base, a limiting block fixedly connected to the inner wall of the sliding groove, a limiting groove formed on the outer wall of the slider, and the outer wall of the limiting block slidably connected to the inner wall of the limiting groove.

[0007] Furthermore, the two ends of the bidirectional lead screw are rotatably connected to the inner wall of the base.

[0008] Furthermore, a steel beam is provided at the middle of the upper end of the base, and wedge-shaped grooves are provided on both sides of the steel beam.

[0009] Furthermore, the outer wall of the wedge block is slidably connected to the inner wall of the wedge groove, the threaded rod passes through the upper clamping block, and the two are connected for rotation and positioning through the waist hole structure.

[0010] Furthermore, the upper clamping block and the lower clamping block are sleeved on the outer wall of the right end of the bidirectional lead screw.

[0011] Furthermore, a groove is provided in the middle of the side plate, and the outer wall of the clamping plate is slidably connected to the inner wall of the groove.

[0012] Furthermore, a diagonal brace is fixedly connected to the lower end of the support plate, and one side of the diagonal brace is fixedly connected to the outer wall of the column.

[0013] This utility model has the following beneficial effects: In this invention, a bidirectional lead screw and slider clamping plate are used to achieve rapid clamping.

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.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a quick-connect steel structure assembly, including a column 1, a support plate 2 fixedly connected to the upper end of the column 1, a diagonal brace 18 fixedly connected to the lower end of the support plate 2, one side of the diagonal brace 18 fixedly connected to the outer wall of the column 1, a base 3 fixedly connected to the upper end of the support plate 2, two side plates 4 fixedly connected to the upper end of the base 3, a sliding groove opened inside the base 3, a limit block 7 fixedly connected to the inner wall of the sliding groove, a limit groove 6 opened on the outer wall of the slider 5, the outer wall of the limit block 7 slidably connected to the inner wall of the limit groove 6, a clamping plate 8 fixedly connected to the upper end of the slider 5, a groove opened in the middle of the side plate 4, the outer wall of the clamping plate 8 slidably connected to the inner wall of the groove, a sliding rod 10 slidably connected to the inner wall of the clamping plate 8, a disc spring assembly 11 sleeved on the outer wall of the middle of the sliding rod 10, and a sliding... A wedge block 12 is fixedly connected to one end of the rod 10. A steel beam 19 is set in the middle of the upper end of the base 3. Wedge grooves 20 are opened on both sides of the steel beam 19. The outer wall of the wedge block 12 is slidably connected to the inner wall of the wedge groove 20. A two-way screw rod 9 is threadedly connected to the middle of the slider 5. The two ends of the two-way screw rod 9 are rotatably connected to the inner wall of the base 3. A handwheel 13 is fixedly connected to the right end of the two-way screw rod 9. A lower clamping block 14 is set in the inner wall of the left end of the base 3. An upper clamping block 15 is rotatably connected to the upper side of one end of the lower clamping block 14. The upper clamping block 15 and the lower clamping block 14 are sleeved on the outer wall of the right end of the two-way screw rod 9. A threaded rod 16 is threadedly connected to the other end of the lower clamping block 14. The threaded rod 16 passes through the upper clamping block 15, and the two are connected to rotate and limit through the waist hole structure. A handle 17 is fixedly connected to the top of the threaded rod 16.

[0019] Specifically, when using this device, firstly, a support plate 2 is welded to the upper end of the column 1 and reinforced with diagonal braces 18 to enhance the stability of the overall structure. Then, the base 3 is fixedly connected to the upper end of the support plate 2 using bolts. The steel beam 19 to be connected is then placed stably on the base 3. Next, the handwheel 13 is turned, driving the bidirectional lead screw 9 to rotate, thereby driving the sliders 5 on both sides to move towards the center. The sliders 5 drive the clamping plates 8 to move closer together, and the wedge blocks 12 on the clamping plates 8 slide into the wedge grooves 20 at the ends of the steel beam 19. Because the wedge blocks 12 have a beveled design, they have an automatic guiding function during the sliding process, allowing for smooth insertion without precise hole alignment. When the wedge blocks 12 are fully inserted into the wedge grooves 20, they compress the disc spring assembly 11 on one side of the wedge blocks 12, causing elastic compression and storing a certain amount of elastic potential energy. This pre-tightening force effectively prevents loosening of the clamping due to external vibrations, thereby improving the reliability of the connection. A slotted hole is provided at the connection between the upper clamping block 15 and the threaded rod 16, allowing the threaded rod 16 to rotate and tilt at a certain angle within it. The bidirectional lead screw 9 has annular grooves at corresponding positions on the upper clamping block 15 and the lower clamping block 14. Once the clamping is stable, rotating the handle 17 rotates the threaded rod 16. Since the threaded rod 16 is only threaded to the lower end of the lower clamping block 14, it moves downwards during rotation, causing the upper clamping block 15 to move downwards as well. This causes the upper clamping block 15 and the lower clamping block 14 to be pressed together within the annular groove of the bidirectional lead screw 9, forming a locking structure to prevent the bidirectional lead screw 9 from rotating during operation, further enhancing the stability of the device. This device has a reasonable structural design, is easy to operate, achieves rapid connection between the column 1 and the steel beam 19, and maintains good clamping performance even under complex vibration environments, demonstrating high practicality and safety.

[0020] Working principle: When using this device, weld the support plate 2 to the upper end of the column 1 and reinforce it with the diagonal brace 18. Fix the base 3 to the upper end of the support plate 2 with bolts. Place the steel beam 19 to be connected on the upper end of the base 3. Rotate the handwheel 13 to drive the double-acting screw 9 to rotate, which drives the two sliders 5 to move closer to the middle. The two clamping plates 8 also move closer to the middle, so that the wedge block 12 slides into the inner wall of the wedge groove 20. Due to the guiding effect of the inclined surface of the wedge block 12, there is no need to deliberately align the hole. After the wedge block 12 slides into the wedge groove 20, it squeezes the disc spring assembly 11, which accumulates elastic potential energy and has a pre-tightening force on the wedge block 12 to prevent the clamping from loosening due to vibration, etc. A slotted hole is provided at the connection between the upper clamping block 15 and the threaded rod 16, allowing the threaded rod 16 to rotate and tilt at a certain angle within it. The bidirectional lead screw 9 has annular grooves at corresponding positions on the upper clamping block 15 and the lower clamping block 14. Once the clamping is stable, rotating the handle 17 rotates the threaded rod 16. Since the threaded rod 16 is only threaded to the lower end of the lower clamping block 14, it moves downwards during rotation, causing the upper clamping block 15 to move downwards as well. This causes the upper clamping block 15 and the lower clamping block 14 to be pressed together within the annular groove of the bidirectional lead screw 9, forming a locking structure to prevent the bidirectional lead screw 9 from rotating on its own. This device allows for faster connection between the column 1 and the steel beam 19 and prevents loosening under vibration.

[0021] Finally, it should be noted that the above description is only 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.
