Description

Technical Field

[0001] This invention relates to the field of building engineering structural technology, and in particular to intelligent prefabricated steel beam-column rigid connection nodes. Background Technology

[0002] Intelligent prefabricated steel beam-column rigid connection nodes represent an innovative achievement in modern construction. They deeply integrate intelligent technology with prefabricated building concepts, achieving efficient and stable connections between steel beams and columns through precise design. These nodes employ standardized and modular designs, facilitating factory prefabrication and significantly improving construction efficiency and quality. On-site, these prefabricated nodes can be quickly and accurately assembled, effectively shortening the construction period and reducing costs. Furthermore, the application of intelligent construction technology makes the node installation process more precise and controllable, enhancing the overall safety and stability of the building structure. Intelligent prefabricated steel beam-column rigid connection nodes are leading the construction industry towards a more efficient, environmentally friendly, and intelligent direction.

[0003] In actual use, traditional construction relies on manual stringing and level calibration. Due to obstructed vision and varying levels of operator proficiency, positioning deviations are significant, easily leading to misalignment of nodes and difficulty in aligning bolt holes. This also requires repeated manual adjustments to the position of the I-beams, which is time-consuming and affects installation efficiency. Therefore, we propose an intelligent construction method for prefabricated steel beam-column rigid connection nodes. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the reliance on manual stringing and leveling in traditional construction, which is affected by obstructed vision and varying operator skill levels, resulting in large positioning deviations that can easily lead to misalignment of nodes and difficulty in aligning bolt holes. Furthermore, it requires repeated manual adjustments to the position of I-beams, which is time-consuming and affects installation efficiency. The invention proposes an intelligent prefabricated steel beam-column rigid connection node.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The intelligent prefabricated steel beam-column rigid connection node includes a connection node with I-beams connected to both sides. Guide housings are provided on both sides of the connection node. An adjustment mechanism is fixedly connected to the upper part of the guide housing, and a guide wheel is provided at the lower part of the adjustment mechanism. First transmission wheels are fixedly connected to both sides of the guide wheels. A transmission belt is driven by the first transmission wheels, and a second transmission wheel is driven by the transmission belt. A first gear is fixedly connected to the second transmission wheel. The first gear meshes with a second gear. A worm gear is fixedly connected to the second gear. A worm gear meshes with a worm wheel. A third gear is fixedly connected to the worm wheel. A positioning rack is meshed with the third gear. A positioning plate is fixedly connected to the positioning rack.

[0006] When connecting the connecting node and the I-beam, the I-beam is hoisted close to the connection point. The upper and lower sides of the I-beam are positioned by guide wheels set on the guide housing. As the I-beam moves closer to the connecting node, it drives the guide wheels to rotate. The rotation of the guide wheels drives the first transmission wheel to rotate, which in turn drives the third gear to rotate. The rotation of the third gear drives the positioning plate to move, thereby automatically pressing the positioning plate against both sides of the I-beam to achieve positioning of the left and right sides of the I-beam. This ensures the positioning effect when the I-beam is connected to the connecting node. The connecting node has connecting holes on both sides, similar to those for mounting bolts. The positioning plate is made of rubber, which serves as a guide and also provides shock absorption during the connection of the I-beam.

[0007] The above technical solution further includes: The second gear is rotatably connected to a positioning housing, which is fixedly connected to the lower part of the guide housing.

[0008] The positioning housing is fixedly connected to a limiting groove, and a positioning rack is slidably connected inside the limiting groove.

[0009] The adjustment mechanism includes an adjustment housing fixedly connected to the upper part of the guide housing, a servo motor is provided on the upper part of the adjustment housing, and an adjustment component is provided at the output end of the servo motor.

[0010] The adjustment assembly includes a threaded rod at the output end of a servo motor, an adjustment rod threadedly connected to the threaded rod, a sliding connection between the adjustment rod and the adjustment housing, a guide wheel rotatably connected to the bottom of the adjustment rod, and a sliding groove provided inside the adjustment housing for the second gear to slide through the sliding groove.

[0011] The bottom of the connection node is fixedly connected to a mounting flange, and the upper part of the connection node is connected to a beam or column.

[0012] Locking housings are fixedly connected to both sides of the connecting node, and a locking pin is provided on the upper part of the guide housing. The guide housing is installed and fixed by inserting the locking pin into the locking housing.

[0013] A piston is slidably connected inside the locking housing. A spring is fixedly connected to the bottom of the piston. A locking steel ball is provided on the upper part of the piston. The locking steel ball is slidably connected to the locking housing. The upper part of the piston and the locking housing can form an unlocking air chamber, while the lower part of the piston and the locking housing form a locking air chamber.

[0014] An air passage is fixedly connected to one side of the locking housing, and an air pump is provided on one side of the air passage. There are two air passages and two air pumps, which are respectively located on the locking air chamber and the unlocking air chamber.

[0015] The present invention has the following beneficial effects: 9. In this invention, during the connection process between the I-beam and the connecting node, the hoisting device controls the I-beam to gradually approach the connecting node. During this approach, the guide wheels on the upper part of the guide housing can position the upper and lower sides of the I-beam. During the positioning process, the movement of the I-beam can cause the guide wheels to rotate due to friction. The rotation of the guide wheels can drive the second gear to rotate, the rotation of the second gear can drive the third gear to move, and the rotation of the third gear can drive the positioning plate to move. Thus, as the I-beam approaches the connecting node, the positioning plate automatically presses against both sides of the I-beam, thereby limiting the movement of both sides of the I-beam and achieving horizontal positioning of the I-beam. Through the combined left and right movement of the guide wheels and the positioning plate, the positioning effect of the I-beam during installation is effectively guaranteed, and the installation efficiency is improved.

[0016] 10. In this invention, locking housings are provided on both sides of the connecting node. After the locking pin provided on the upper part of the guide housing is inserted into the locking housing, the air pump on one side of the locking air chamber is started to send air into the locking air chamber, thereby increasing the air pressure inside the locking air chamber. The piston can rise rapidly under the combined action of positive pressure and spring, thereby driving the locking steel ball to lock inward and lock the locking pin. This effectively improves the installation efficiency of the guide housing. After the I-beam is connected, the fixation of the guide housing can also be quickly released, which facilitates the installation and disassembly of the guide housing and improves the use effect of the device.

Detailed Implementation

[0019] 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.

[0020] Example 1 like Figures 1-7 As shown, the intelligent prefabricated steel beam-column rigid connection node includes a connection node 1. I-beams 3 are connected to both sides of the connection node 1. Guide housings 6 are set on both sides of the connection node 1. An adjustment mechanism is fixedly connected to the upper part of the guide housing 6. A guide wheel 9 is set at the lower part of the adjustment mechanism. A first transmission wheel 11 is fixedly connected to both sides of the guide wheel 9. The first transmission wheel 11 is driven by a transmission belt 12. The transmission belt 12 is driven by a second transmission wheel 21. The second transmission wheel 21 is fixedly connected to a first gear 13. The first gear 13 meshes with a second gear 14. The second gear 14 is fixedly connected to a worm 25. The worm 25 meshes with a worm wheel 26. The worm wheel 26 is fixedly connected to a third gear 27. The third gear 27 meshes with a positioning rack 28. The positioning rack 28 is fixedly connected to a positioning plate 20.

[0021] When connecting node 1 and I-beam 3, I-beam 3 is hoisted close to the connection point. The guide wheel 9 on the guide housing 6 is used to position the upper and lower sides of I-beam 3. As I-beam 3 moves closer to connecting node 1, it drives the guide wheel 9 to rotate. The rotation of the guide wheel 9 drives the first transmission wheel 11 to rotate. The rotation of the first transmission wheel 11 drives the third gear 27 to rotate. The rotation of the third gear 27 drives the positioning plate 20 to move, thereby automatically driving the positioning plate 20 to press the sides of I-beam 3, realizing the positioning of the left and right sides of I-beam 3, and ensuring the positioning effect when I-beam 3 is connected to connecting node 1. Connecting holes similar to mounting bolts are opened on both sides of connecting node 1. The positioning plate 20 is made of rubber, which not only plays a guiding role, but also provides shock absorption during the connection of I-beam 3.

[0022] The second gear 14 is rotatably connected to a positioning housing 7, which is fixedly connected to the lower part of the guide housing 6. A limit groove 29 is fixedly connected inside the positioning housing 7, and a positioning rack 28 is slidably connected inside the limit groove 29. The adjustment mechanism includes an adjustment housing 8 fixedly connected to the upper part of the guide housing 6. A servo motor 22 is provided on the upper part of the adjustment housing 8, and an adjustment component is provided at the output end of the servo motor 22. The adjustment component includes a threaded rod 23 provided at the output end of the servo motor 22, and an adjustment rod 24 is threadedly connected to the threaded rod 23. The adjustment rod 24 is slidably connected to the adjustment housing 8, and a guide wheel 9 is rotatably connected to the bottom of the adjustment rod 24. A sliding groove is provided inside the adjustment housing 8, through which the second gear 14 is slidably connected.

[0023] In this embodiment, during the connection process between the I-beam 3 and the connecting node 1, the hoisting device controls the I-beam 3 to gradually approach the connecting node 1. During the approach process, the guide wheel 9 set on the upper part of the guide housing 6 can position the upper and lower sides of the I-beam 3. Moreover, the servo motor 22 can drive the threaded rod 23 to rotate. The rotation of the threaded rod 23 drives the threaded adjustment rod 24 to move, which in turn drives the guide wheel 9 to move, thereby adjusting the positioning range according to the different specifications of the I-beam 3.

[0024] During the positioning process, the movement of the I-beam 3 causes the guide wheel 9 to rotate through friction. The rotation of the guide wheel 9 then causes the first transmission wheel 11 to rotate. The rotation of the first transmission wheel 11 causes the transmission belt 12 to rotate, which in turn causes the second transmission wheel 21 to rotate. The rotation of the second transmission wheel 21 causes the fixedly connected first gear 13 to rotate, which in turn causes the meshing second gear 14 to rotate. The rotation of the second gear 14 causes the fixedly connected worm gear 25 to move, which in turn causes the meshing worm wheel 26 to rotate. The rotation of the worm wheel 26 then causes the fixedly connected worm gear 25 to move. The rotation of the third gear 27 drives the meshing positioning rack 28 to move. During the movement of the positioning rack 28, the slidingly connected limiting groove 29 ensures the stability of the positioning rack 28. The movement of the positioning rack 28 drives the fixedly connected positioning plate 20 to move. As the I-shaped steel 3 approaches the connection node 1, the positioning plate 20 automatically presses against both sides of the I-shaped steel 3, thereby limiting the two sides of the I-shaped steel 3 and achieving horizontal positioning of the I-shaped steel 3. Through the combined left and right movement of the guide wheel 9 and the positioning plate 20, the positioning effect of the I-shaped steel 3 during installation is effectively guaranteed, and the installation efficiency is improved.

[0025] Example 2 like Figures 1-7As shown, a mounting flange 4 is fixedly connected to the bottom of the connecting node 1, a beam and column 2 are connected to the upper part of the connecting node 1, and locking housings 5 ​​are fixedly connected to both sides of the connecting node 1. A locking pin 10 is provided on the upper part of the guide housing 6. The guide housing 6 is installed and fixed by inserting the locking pin 10 into the locking housing 5.

[0026] A piston 16 is slidably connected inside the locking housing 5. A spring 18 is fixedly connected to the bottom of the piston 16. A locking steel ball 17 is provided on the upper part of the piston 16. The locking steel ball 17 is slidably connected to the locking housing 5. The upper part of the piston 16 and the locking housing 5 can form an unlocking air chamber, while the lower part of the piston 16 and the locking housing 5 form a locking air chamber. An air passage 19 is fixedly connected to one side of the locking housing 5. An air pump 15 is provided on one side of the air passage 19. There are two air passages 19 and two air pumps 15, which are respectively provided on one side of the locking air chamber and the unlocking air chamber.

[0027] In this embodiment, locking housings 5 ​​are provided on both sides of the connecting node 1. After the locking pin 10 provided on the upper part of the guide housing 6 is inserted into the locking housing 5, the air pump 15 on one side of the locking air chamber is activated to send air into the locking air chamber, thereby increasing the air pressure inside the locking air chamber. The piston 16 can rise rapidly under the combined action of positive pressure and spring 18, thereby driving the locking steel ball 17 to lock inward and lock the locking pin 10. This quickly realizes the installation and fixation of the guide housing 6, effectively improving the installation efficiency of the guide housing 6. After the I-shaped steel 3 is connected, air can be circulated into the unlocking air chamber through the air pump 15. The increased air pressure inside the unlocking air chamber can drive the piston 16 to move downward, thereby releasing the locking steel ball 17 from locking the locking pin 10, allowing the locking pin 10 to be reinserted and removed, facilitating the installation and disassembly of the guide housing 6, and improving the use effect of the device.
