[0002] In the field of modern construction engineering, steel structures, with their significant advantages such as high strength, light weight, short construction period, and recyclability, have become the preferred structural form for major projects such as super high-rise buildings, long-span bridges, and large stadiums. Steel structures form a complete load-bearing system through the joint connections between various components. As key hubs for force transmission, the mechanical properties of these joints directly determine the overall load-bearing capacity, seismic performance, and service life of the structure. Related research indicates that over 60% of steel structure accidents are caused by joint connection failures; therefore, innovation in joint technology is crucial for promoting the development of the steel structure industry.

[0003] Traditional steel structure joint connection methods, such as welding and ordinary bolt connections, have certain limitations. Welding connections require on-site hot work, posing safety hazards, and the welding quality is greatly affected by the operator's skill level, making it prone to welding defects. Although ordinary bolt connections are convenient to install, during long-term use, factors such as vibration and load changes can cause the bolts to loosen, leading to joint failure and reducing the safety and stability of the steel structure.

[0025] 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.

[0026] like Figures 1 to 5As shown, this utility model provides a large-scale safety steel structure node component, including a main node connecting seat 1 and a vertical I-beam A11 inserted into slots at both ends of the main node connecting seat 1. The I-beam A11 is fixedly installed in the slots at both ends of the main node connecting seat 1 by bolts. Also included are I-beams B12 arranged laterally on the main node connecting seat 1. A connecting component 2 is provided at the connection point between the I-beam B12 and the main node connecting seat 1.

[0027] The connecting assembly 2 includes guide grooves 21 symmetrically formed on the side surface of the main node connecting seat 1. Each guide groove 21 has an adjusting bolt 24 inside. One end of the adjusting bolt 24 is inserted into the guide groove 21 and rotatably connected to the inner wall of the guide groove 21. The other end of the adjusting bolt 24 extends to the outside of the main node connecting seat 1 and connects to a rotating seat located on the outside of the main node connecting seat 1. The rotating seat has an internal hexagonal groove at its center and is equipped with a corresponding rotating tool. A moving block 22 is screwed onto the surface of the adjusting bolt 24. The moving block 22 slides inside the guide groove 21. A limiting block 23 is integrally formed on the surface of the moving block 22 and engages in a groove on the side surface of the I-beam B12. By rotating the adjusting bolt 24, the moving block 22 can be moved within the guide groove 21, thereby causing the limiting block 23 to engage or disengage the I-beam B12, achieving a quick and reliable connection between the I-beam B12 and the main node connecting seat 1.

[0028] It should be noted that the movable block 22 is designed with a convex shape and is adapted to the guide groove 21, which ensures that the movable block 22 slides stably in the guide groove 21 and improves the fixation of the I-beam.

[0029] It should be noted that a threaded rod is provided in the threaded hole on the surface of the limiting block 23. The threaded rod passes through the limiting block 23 and is inserted into the threaded hole on the surface of the I-beam B12, which further enhances the connection strength between the limiting block 23 and the I-beam B12.

[0030] like Figures 1 to 5As shown, the system also includes reinforcing components 3 at both ends of the main node connecting seat 1. Each reinforcing component 3 includes support rods 31 symmetrically arranged on both sides of the end of the main node connecting seat 1 via hinged seats. The other end of each support rod 31 is connected to a concave-shaped sleeve 32 via a hinged seat. The sleeve 32 is adapted to the I-beam B12. Both sides of the sleeve 32 have receiving grooves 34, and each receiving groove 34 contains an abutment block 35, which is adapted to the receiving groove 34. A threaded hole on the surface of the sleeve 32 is inserted into a lead screw 33. One end of the lead screw 33 passes through the sleeve 32 and is rotatably connected to the abutment block 35, which contacts the I-beam B12. By rotating the lead screw 33, the abutment block 35 can be pushed out of the receiving groove 34 and pressed against the I-beam B12, enhancing the connection stability between the main node connecting seat 1 and the I-beam B12.

[0031] To better fit with the I-beam B12, the abutment block 35 is adapted to the groove on the side surface of the I-beam B12, and an anti-slip pad is provided on the side surface of the abutment block 35 near the I-beam B12 to increase the friction between the abutment block 35 and the I-beam B12 and prevent the abutment block 35 from sliding.

[0032] To improve the corrosion resistance of the main node connector 1 and extend the service life of the steel structure node components, the surface of the main node connector 1 is coated with an anti-corrosion coating. The anti-corrosion coating adopts a composite coating structure of epoxy zinc-rich primer and polyurethane topcoat.

[0033] Working principle and process: Insert the vertical I-beam A11 into the slots at the top and bottom of the main node connector 1. Adjust the position of the I-beam A11 to align it with the slot. Use bolts to fix the I-beam A11 in the slots at the top and bottom of the main node connector 1. Tighten the bolts sequentially according to the specified torque to ensure a firm connection. During tightening, a symmetrical tightening method can be used to ensure even force distribution. Place the I-beam B12 in the lateral installation position of the main node connector 1, so that the groove on the side surface of the I-beam B12 corresponds to the guide groove 21 on the side surface of the main node connector 1. Use an Allen wrench to insert into the Allen groove of the rotating seat outside the adjusting bolt 24. Rotate the adjusting bolt 24 to drive the moving block 22 to slide in the guide groove 21, so that the limiting block 23 gradually engages in the groove on the side surface of the I-beam B12. When the limiting block 23 is fully engaged in the groove, use a screwdriver to screw the matching threaded rod into the limiting block 23 and the surface of the I-beam B12. Inside the threaded hole, the limiting block 23 and the I-beam B12 are further fixed to enhance the connection strength. The support rod 31 is symmetrically installed on both sides of the end of the main node connecting seat 1 through the hinge seat. The angle of the support rod 31 is adjusted to make it in a suitable support position. The concave structure sleeve 32 is connected to the other end of the support rod 31 through the hinge seat, and the sleeve 32 is put on the I-beam B12 to ensure that the sleeve 32 is compatible with the I-beam B12. The screw rod 33 is rotated with a screwdriver to push the abutment block 35 out of the receiving groove 34 so that the abutment block 35 is in close contact with the groove on the side surface of the I-beam B12 and abuts tightly. Continue rotating the lead screw 33 until the abutment block 35 firmly secures the I-beam B12, enhancing the connection stability between the main node connector 1 and the I-beam B12. After completing the installation of all components, conduct a comprehensive inspection of the entire steel structure node components, checking whether the connections of each component are secure, whether the bolts are tightened, and whether the adjusting bolts 24, lead screw 33, etc., are in the correct positions. Check whether the verticality, horizontality, and spacing of the main node connector 1, I-beam A11, and I-beam B12 meet the design requirements. If there are any deviations, adjust them promptly.
