Description

Technical Field

[0001] This utility model relates to the field of steel structure node reinforcement technology, and more specifically, to a steel structure wind-resistant node reinforcement connection component. Background Technology

[0002] With the development of modern construction technology, steel structures are widely used in important projects such as high-rise buildings and long-span bridges due to their high strength and good ductility. However, when facing natural disasters such as strong winds or earthquakes, the stability of steel structure nodes becomes one of the key factors to ensure the safety of the overall structure. The traditional connection between H-shaped steel beams and crossbeams usually uses right-angle brackets and is fixed with a large number of bolts. In addition, diagonal beams are often used to reinforce the crossbeams. During construction and installation, welding, on-site grooving, and opening are usually required depending on the actual situation. The construction is relatively complex and costly. Moreover, the right-angle brackets combined with diagonal beams are difficult to adapt to and withstand the damage to the nodes caused by natural disasters such as strong winds or earthquakes. The connection stability is still insufficient, and bolt loosening and crossbeam deformation are prone to occur. It is difficult to meet the needs of different working conditions. In view of this, we propose a steel structure wind-resistant node reinforcement connection component. Utility Model Content

[0003] The purpose of this utility model is to provide a steel structure wind-resistant node reinforcement connection component, which solves the technical problems in the background art mentioned above. This node reinforcement connection component significantly improves the connection strength and wind resistance of steel structure nodes. Through the synergistic effect of the elastic compression plate and the reinforcement mechanism, it effectively prevents relative displacement caused by wind force, enhances the stability of the structure, and simplifies the installation process and improves construction efficiency by modular assembly design, while also facilitating later maintenance.

[0004] This utility model provides a steel structure wind-resistant node reinforcement connection component, including: an I-shaped vertical beam and transverse square tubes symmetrically installed on both sides of the I-shaped vertical beam. A reinforcement structure is threadedly fixed to both sides of the web of the I-shaped vertical beam. The reinforcement structure includes an isosceles trapezoidal block and a long plate, which are integrally fixedly connected. Multiple bolts are threadedly fixed between the isosceles trapezoidal blocks. An elastic compression plate is provided on both sides of the web of the I-shaped vertical beam at the location of the isosceles trapezoidal block. A positioning element is connected between the end of the transverse square tube near the I-shaped vertical beam and the elastic compression plate and the flange of the I-shaped vertical beam. A rectangular plate is welded and fixed to the upper surface of the end of the transverse square tube away from the I-shaped vertical beam. Two arc-shaped support plates are detachably connected to the transverse square tube through the rectangular plates. The bottom end of the arc-shaped support plate penetrates through the flange of the I-shaped vertical beam and is limited by a rectangular block installed between it and the long plate.

[0005] Optionally, two rectangular slots are provided on the flange of the I-shaped vertical beam and on both sides of the web. Two plug-in blocks are fixed at the bottom of the arc-shaped support plate. The plug-in blocks movably pass through the corresponding rectangular slots on the I-shaped vertical beam and abut against the elongated plate. The rectangular blocks are welded and fixed to the elongated plate. The rectangular blocks are close to the outside of the plug-in blocks. Four bolts are threaded between the rectangular blocks and the four bolts pass through the web of the I-shaped vertical beam.

[0006] Optionally, the two arc-shaped support plates at the bottom of the horizontal square tube are arranged at the same center and bend away from the horizontal square tube. A connecting plate is fixed at the upper end of each arc-shaped support plate. Bolts are threaded between the two ends of the rectangular plate and the connecting plate, and bolts penetrate the horizontal square tube.

[0007] Optionally, the positioning component includes a square sleeve fitted over the end of the transverse square tube and a positioning plate welded to the port of the square sleeve. The square sleeve is threadedly fixed to the transverse square tube with multiple bolts. Two inclined bracing plates are welded to the bottom surface of the square sleeve. The inclined bracing plates are threadedly fixed to two arc-shaped support plates installed on the corresponding transverse square tube with bolts. The positioning plate is attached to the wing plate surface of the I-shaped vertical beam, and both ends are bent to form U-shaped buckles, which are fastened to the wing plate of the I-shaped vertical beam. Both ends of the elastic compression plate are integrally fixed with barbed plates, and the barbed plate part is tightly inserted between the wing plate of the I-shaped vertical beam and the U-shaped buckle, and is threadedly fixed with multiple bolts.

[0008] Optionally, the web, isosceles trapezoidal block, and elastic compression plate of the I-shaped vertical beam are each provided with three screw holes, which are provided one-to-one for threaded installation of bolt five. Bolt five is a tightening bolt structure. When bolt five is tightened, the elastic compression plate elastically deforms, and the barbed plates at both ends laterally compress the corresponding bolt three.

[0009] Optionally, the elastic extrusion plate is an isosceles trapezoidal plate structure, and combined with the barbed plates at both ends, it generally forms a ∑-shaped structure. The trapezoidal inclined surface of the elastic extrusion plate abuts against the isosceles trapezoidal block, and the barbed plates abut against the web surface of the I-shaped vertical beam.

[0010] One or more technical solutions provided in this utility model have at least the following technical effects or advantages: 1. By setting up elastic compression plates and barbed plates, the connection between the I-shaped vertical beam and the horizontal square tube can be tightly fixed with the positioning components. Multiple bolts are used to firmly install the square sleeve at the end of the horizontal square tube, and the U-shaped buckle plate is fastened to the flange of the I-shaped vertical beam. By locking bolt five, the elastic compression plate compresses the isosceles trapezoidal block, increasing the frictional resistance and preventing slippage. The elastic deformation trend allows the barbed plate to compress and limit the bolt three used to fix the U-shaped buckle plate and the I-shaped vertical beam in the horizontal direction, achieving the anti-loosening effect. This makes the connection between the positioning plate and the main beam more stable and reliable. In addition, a reinforcement mechanism composed of isosceles trapezoidal blocks, long plates and rectangular blocks is specially set to help bear additional tensile stress, ensuring that sufficient load-bearing capacity can be maintained even under extreme conditions without failure. This significantly improves the stiffness and stability of the entire structure. Especially when facing external wind forces, this design can effectively prevent relative displacement caused by shear force and bending moment load. 2. The square sleeve is fixedly welded with diagonal bracing plates and then fixed with bolts to two corresponding arc-shaped support plates. This allows each transverse square tube to be effectively supported and reinforced with two arc-shaped support plates. By combining various reinforcing structural components, the reinforced connection components of this node can achieve the purpose of prefabricated assembly. Standardized parts and easy-to-operate threaded connection methods are used to replace traditional welding processes, which greatly reduces labor intensity and improves work efficiency. The assembly efficiency is high and the construction is convenient. Without affecting the aesthetics, it effectively improves the ability of the steel structure node area to resist the impact of severe weather. Attached Figure Description

[0012] The present invention will be further described in detail below with reference to the accompanying drawings.

[0013] Reference Figures 1 to 3 This utility model embodiment provides a steel structure wind-resistant node reinforcement connection component, including: an I-shaped vertical beam 1 and transverse square tubes 3 symmetrically installed on both sides of the I-shaped vertical beam 1. A reinforcement structure 5 is threadedly fixed to both sides of the web of the I-shaped vertical beam 1. The reinforcement structure 5 includes isosceles trapezoidal blocks 51 and elongated plates 52, which are integrally fixedly connected. Multiple bolts 55 are threadedly fixed between the isosceles trapezoidal blocks 51. The web of the I-shaped vertical beam 1... An elastic extrusion plate 4 is provided on both sides and at the isosceles trapezoidal block 51. A positioning element 2 is connected between the end of the transverse square tube 3 near the I-shaped vertical beam 1 and the elastic extrusion plate 4 and the wing plate of the I-shaped vertical beam 1. A rectangular plate 7 is welded and fixed to the upper surface of the end of the transverse square tube 3 away from the I-shaped vertical beam 1. Two arc-shaped support plates 6 are detachably connected to the transverse square tube 3 through the rectangular plate 7. The bottom end of the arc-shaped support plate 6 passes through the wing plate of the I-shaped vertical beam 1 and a rectangular block 53 is installed between it and the elongated plate 52 for limiting.

[0014] By adopting the above technical solution, a transverse square tube 3 is installed on each side of the I-shaped vertical beam 1. A reinforcing structure 5, composed of an isosceles trapezoidal block 51, a long plate 52, and a rectangular block 53, is installed on both sides of the web of the I-shaped vertical beam 1. These three components are integrally formed and firmly fixed to the web of the I-shaped vertical beam 1 with multiple bolts 55 to enhance the tensile strength of the I-shaped vertical beam 1. Elastic compression plates 4 are installed on both sides of the web of the I-shaped vertical beam 1 at the isosceles trapezoidal block 51, which can generate appropriate preload to ensure sufficient friction between the contact surfaces to prevent slippage. This, combined with positioning... The horizontal square tube 3 is securely installed in component 2. Two arc-shaped support plates 6 are also connected between the horizontal square tube 3 and the I-shaped vertical beam 1. The bottom of the arc-shaped support plate 6 can penetrate through the I-shaped vertical beam 1, and the through-section structure can limit and fix the rectangular plate 7 and the I-shaped vertical beam 1. The arc-shaped support plate 6 is also connected to the positioning component 2, so that the I-shaped vertical beam 1 and the horizontal square tube 3 form a very stable support structure. The design of the arc-shaped support plate 6 increases the resistance of the horizontal square tube 3, and the deformation buffering capacity of the arc-shaped support plate 6 effectively protects the horizontal square tube 3 from bending and deformation, thus ensuring the reliability of long-term use.

[0015] Reference Figure 1 and Figure 2Two rectangular slots 11 are provided on the flange of the I-shaped vertical beam 1 and on both sides of the web. Two plug-in blocks 62 are fixed at the bottom of the arc-shaped support plate 6. The plug-in blocks 62 movably pass through the corresponding rectangular slots 11 on the I-shaped vertical beam 1 and abut against the elongated plate 52. The rectangular blocks 53 are welded and fixed to the elongated plate 52. The rectangular blocks 53 are close to the plug-in blocks 62. Bolts 54 are threaded between the rectangular blocks 53 and the bolts 54 pass through the web of the I-shaped vertical beam 1.

[0016] By adopting the above technical solution, the plug block 62 fixed at the bottom of the arc-shaped support plate 6 moves through the rectangular slot 11 corresponding to the I-shaped vertical beam 1 and abuts against the elongated plate 52. Then, bolts 54 that penetrate the web of the I-shaped vertical beam 1 are installed between the rectangular blocks 53 to achieve a more stable fixing effect.

[0017] Reference Figure 1 and Figure 2 The two arc-shaped support plates 6 at the bottom of the horizontal square tube 3 are arranged at the same center and bend away from the horizontal square tube 3. The upper end of each arc-shaped support plate 6 is fixed with a connecting plate 61. The two ends of the rectangular plate 7 are threadedly fixed with bolts 71 between the connecting plate 61 and the bolts 71, which penetrate the horizontal square tube 3.

[0018] By adopting the above technical solution, the two arc-shaped support plates 6 below the horizontal square tube 3 are arranged to bend outward based on the same center. The arc-shaped structure of the arc-shaped support plate 6 effectively absorbs the deformation impact energy of the horizontal square tube 3 and realizes the reset function of the horizontal square tube 3. The top of the arc-shaped support plate 6 is connected to the rectangular plate 7 above through the connecting plate 61 and bolt 71, which helps to evenly distribute the pressure load and also facilitates disassembly and maintenance.

[0019] Reference Figure 2 and Figure 3 The positioning component 2 includes a square sleeve 21 sleeved on the outside of the end of the transverse square tube 3 and a positioning plate 22 welded to the port of the square sleeve 21. The square sleeve 21 and the transverse square tube 3 are threadedly fixed with multiple bolts 24. Two inclined plates 23 are welded and fixed to the bottom surface of the square sleeve 21. The inclined plates 23 and the two arc-shaped support plates 6 installed on the corresponding transverse square tube 3 are threadedly fixed with bolts 25. The positioning plate 22 is attached to the wing plate surface of the I-shaped vertical beam 1, and the two ends are bent to form U-shaped buckle plates 221, which are fastened to the wing plate of the I-shaped vertical beam 1. The elastic compression plate 4 has barbed plates 41 integrally fixed at both ends, and the barbed plates 41 are partially inserted tightly between the wing plate of the I-shaped vertical beam 1 and the U-shaped buckle plates 221, and are threadedly fixed with multiple bolts 26.

[0020] By adopting the above technical solution, the positioning component 2 is composed of a square sleeve 21 that wraps around the end of the transverse square tube 3, a positioning plate 22, and a diagonal brace 23. The two diagonal braces 23 extending from the bottom of the square sleeve 21 are also connected to the corresponding arc-shaped support plates 6 to enhance the connection strength of the arc-shaped support plates 6. The U-shaped buckles 221 at both ends of the positioning plate 22 can lock the flange edge of the I-shaped vertical beam 1 to prevent it from moving up and down. At the same time, the mechanical locking effect formed by the barbed plate 41 inserted into the U-shaped buckle 221 and the flange of the I-shaped vertical beam 1 further enhances the ability to resist deformation.

[0021] Reference Figure 1 and Figure 2 The web, isosceles trapezoidal block 51, and elastic compression plate 4 of the I-shaped upright beam 1 are each provided with three screw holes, which are provided one-to-one for threaded installation of bolt 55. Bolt 55 is a tightening bolt structure. When bolt 55 is tightened, the elastic compression plate 4 elastically deforms, and the barbed plates 41 at both ends laterally compress the corresponding bolt 26.

[0022] By adopting the above technical solution, a corresponding number of small holes are reserved in the web area of ​​the I-shaped upright beam 1 itself, the surface of the isosceles trapezoidal block 51 for reinforcement, and the elastic compression plate 4. They are arranged neatly in correspondence with each other. Each time a standard bolt 55 is screwed in, a moderate pressure difference can be forced between adjacent parts, thereby achieving the purpose of locking.

[0023] Reference Figure 1 and Figure 2 The elastic extrusion plate 4 is an isosceles trapezoidal plate structure, and is generally ∑-shaped with the hook plates 41 set at both ends. The trapezoidal inclined surface of the elastic extrusion plate 4 abuts against the isosceles trapezoidal block 51, and the hook plates 41 abut against the web surface of the I-shaped vertical beam 1.

[0024] By adopting the above technical solution, the elastic compression plate 4 includes an isosceles trapezoidal plate structure and barbed plates 41 at both ends. The overall integrated structure forms a ∑-shaped structure with the opening facing outward, so that even under strong impact, the entire structure can still remain stable and undeformed.

[0025] Working principle: When external wind force acts on the steel structure, the joints of the steel structure will bear large shear force and bending moment loads. The transverse square tubes 3 installed on both sides of the I-shaped vertical beam 1 will attempt to displace relative to the main beam. The ends of the transverse square tubes 3 are fixedly installed with square sleeves 21 using multiple bolts 24. The square sleeves 21 are integrally fixedly connected to the positioning plates 22. The two ends of the positioning plates 22 are bent into U-shaped buckle plates 221 and fastened to the flanges of the I-shaped vertical beam 1. By tightening the bolts 55 between the elastic compression plates 4, the displacement is achieved. The trapezoidal surface of the elastic compression plate 4 compresses the isosceles trapezoidal block 51, exhibiting a certain elastic deformation tendency. This allows the barbed plates 41 at both ends to compress and limit the bolts 26 used to fix the U-shaped buckle plate 221 and the flange of the I-shaped upright beam 1 in the horizontal direction. This enables the bolts 26 to exert lateral pressure, preventing them from loosening and greatly improving the connection strength between the positioning plate 22 and the I-shaped upright beam 1. A reinforcement mechanism consisting of an isosceles trapezoidal block 51, a long plate 52, and a rectangular block 53 is respectively set on both sides of the web of the I-shaped upright beam 1. 5. The reinforced I-beam 1 can be reinforced to help bear additional tensile stress, ensuring sufficient load-bearing capacity even under extreme conditions without failure. In addition, two concentric arc-shaped support plates 6 are connected between the transverse square tube 3 and the I-beam 1. The bottom of the arc-shaped support plate 6 passes through the flange of the I-beam 1 through the plug block 62, and the rectangular block 53, the plug block 62 and the web of the I-beam 1 are locked and limited by bolts 4 54. The upper end of the arc-shaped support plate 6 is fixed to the transverse square tube 3 by the connecting plate 61 and the bolts 6 71. The diagonal bracing plate 23 fixedly welded to the square sleeve 21 is fixed to the corresponding two arc-shaped support plates 6 by bolts 25. This allows each transverse square tube 3 and the I-beam 1 to be effectively supported and reinforced by two arc-shaped support plates 6. By combining the synergistic effect of various reinforcement structural components, the reinforcement connection component of this node can achieve the purpose of prefabricated assembly, which has high assembly efficiency and convenient construction. Without affecting the aesthetics, it effectively improves the ability of the steel structure node area to resist the impact of severe weather.
