Description

Technical Field

[0001] This utility model belongs to the field of building steel structure technology, and in particular relates to a reinforcement component for connecting steel beams and wedge plates in building steel structures. Background Technology

[0002] Steel beams are commonly used load-bearing components in steel structure buildings. Made of steel, they possess high strength, good plasticity, and convenient construction characteristics, making them widely used in building frames. Wedge plates, on the other hand, are steel plate components with trapezoidal or wedge-shaped cross-sections, often used in conjunction with steel beams. The reliability of their connection nodes directly affects the safety and stability of the overall structure. Therefore, we need to design a reinforcement component for connecting steel beams and wedge plates in steel structures. Wedge plate reinforcement can disperse stress, reduce fatigue risk, and is convenient to construct, saving construction time. It can also improve node stiffness and ductility, enhancing structural safety. Utility Model Content

[0003] The purpose of this utility model is to provide a reinforcement component for connecting steel beams and wedge plates in building steel structures. The wedge plate reinforcement can disperse stress, reduce fatigue risk, facilitate construction, save construction time, improve node stiffness and ductility, and enhance structural safety, thereby solving the above-mentioned technical problems.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A steel beam and wedge plate connection reinforcement component in a building steel structure, comprising a steel beam, wherein H-beams are provided on the left and right sides and the front side of the steel beam, and two symmetrical wedge plates are fixedly connected to the top and bottom of the three H-beams. Reinforcing members are fixedly connected to the top and bottom of the wedge plates on the left and right sides by bolts. An L-shaped plate is fixedly connected to the front side of the two H-beams by bolts. Two symmetrical node plates are fixedly connected to the opposite side of the two wedge plates on the front side. The two node plates are fixedly connected to the front H-beams by bolts. A reinforcing plate is fixedly connected to the opposite side of the two wedge plates on the front side. The reinforcing plate extends through the left and right sides of the steel beam and is fixedly connected to the wedge plates on both sides. Limiting end seats are fixedly connected to the bottom of the three H-beams. Reinforcing rods are fixedly connected to the central axis of the bottom of the three H-beams by bolts.

[0005] Preferably, a stiffening plate is fixedly connected to the inner side of the I-beam.

[0006] Preferably, a mounting plate is fixedly connected to the lower front side of the steel beam.

[0007] Preferably, the left and right sides of the steel beam are fixedly connected to the front side of the mounting plate with bottom hinge seats, and the limiting end seat and the side facing the bottom hinge seat are fixedly connected to the diagonal bracing rod by bolts.

[0008] Preferably, a stabilizing plate is fixedly connected to the bottom of each of the three reinforcing rods, and the stabilizing plate is fixedly connected to the diagonal brace connecting rod.

[0009] The beneficial effects of this utility model are:

[0010] 1. This utility model, through the combined use of reinforcement components, L-shaped plates and node plates, makes the position of the three I-beams more stable when connected to the two sides and the front side of the steel beam. In turn, it makes the connection between the multiple wedge plates and the steel beam and the I-beams more stable. This achieves the purpose of wedge plate reinforcement to disperse stress, reduce fatigue risk, facilitate construction, save construction time, improve node stiffness and ductility, and enhance structural safety.

[0011] 2. By setting stiffening plates, the longitudinal stiffening plates at the flange edge of the present invention can increase the lateral stiffness of the flange of the I-beam and suppress its out-of-plane bending deformation. For wide flange I-beams, the stiffening plates together with the web and flange of the I-beam form a "constraint system", which is equivalent to reducing the free length of the flange and increasing the buckling critical load.

[0012] 3. Through the setting of the stabilizing plate, the stabilizing plate plays a role in the stable connection and synergistic effect of the reinforcing rod. When subjected to external force, the stabilizing plate can effectively transfer and disperse the load, enhance the stability of the reinforcing rod, and prevent it from deforming or shifting due to uneven force. The combination of the two can also improve the rigidity and strength of the overall structure. Attached Figure Description

[0020] In the following description, embodiments of the steel beam and wedge plate connection reinforcement component in the building steel structure of this utility model will be described with reference to the accompanying drawings.

[0021] Figure 1-4 This invention illustrates a steel beam and wedge plate connection reinforcement assembly in a building steel structure according to an embodiment of the present invention. It includes a steel beam 1, with I-beams 2 on the left, right, and front sides of the beam 1. Two symmetrical wedge plates 3 are fixedly connected to the top and bottom of each of the three I-beams 2. Reinforcing members 4 are bolted to the top and bottom of the wedge plates 3 on the left and right sides. An L-shaped plate 5 is bolted to the front side of the two I-beams 2. Two symmetrical node plates 6 are fixedly connected to the facing side of the two front wedge plates 3, and the two node plates 6 are bolted to the front I-beams 2. A reinforcing plate 7 is fixedly connected to the facing side of the two front wedge plates 3, extending through the left and right sides of the steel beam 1 and fixedly connected to the wedge plates 3 on both sides. A stiffening plate 8 is fixedly connected to the inner side of the I-beams 2. By setting the stiffening plate 8, longitudinal stiffening plates 8 are provided at the flange edges, which can increase the lateral stiffness of the flanges of the I-beams 2 and suppress their out-of-plane bending deformation. For wide-flange I-beams... 2. The stiffening plate 8, together with the web and flanges of the I-beam 2, forms a "constraint system," which effectively reduces the free length of the flanges and increases the critical buckling load. A mounting plate 9 is fixedly connected to the lower front side of the steel beam 1. Bottom hinge seats 11 are fixedly connected to both sides of the steel beam 1 and the front side of the mounting plate 9. A diagonal bracing rod 12 is bolted to the side of the limiting end seat 10 facing the bottom hinge seat 11. Limiting end seats 10 are fixedly connected to the bottom of each of the three I-beams 2. Each of the three reinforcing rods 13 is fixed to the central axis of the structure with bolts. The bottom of each reinforcing rod 13 is fixedly connected to a stabilizing plate 14. The stabilizing plate 14 is fixedly connected to the diagonal brace 12. Through the setting of the stabilizing plate 14, the stabilizing plate 14 plays a role in stabilizing the connection and synergistic effect of the reinforcing rod 13. When subjected to external force, the stabilizing plate 14 can effectively transfer and distribute the load, enhance the stability of the reinforcing rod 13, and prevent it from deforming or shifting due to uneven force. The combination of the two can also improve the rigidity and strength of the overall structure.

[0022] Working principle: When using this utility model, the user fixes multiple wedge plates 3 to the top and bottom of three I-beams 2, and then the two node plates 6 are fixedly connected to the front I-beam 2 with bolts. The L-shaped plates 5 are fixed to the front and rear sides of the left and right I-beams 2 with bolts. Then the reinforcement 4 is fixedly connected to the top and bottom of the I-beams 2 and the wedge plates 3 with bolts. Next, the front bottom hinge seat 11 is fixed to the front side of the mounting plate 9. Then the two bottom hinge seats 11 are fixed to the lower sides of the steel beam 1 with bolts. The two ends of the diagonal brace 12 are fixed to the side of the limiting end seat 10 and the bottom hinge seat 11 facing each other with bolts. The stiffening plate 8 reinforces the I-beam 2. Then the stabilizing plate 14 is fixedly connected to the I-beam 2 with bolts. The reinforcing rod 13 is supported on the top of the diagonal brace 12.

[0023] In summary, the steel beam and wedge plate connection reinforcement components in this building steel structure, through the combined use of reinforcement components 4, L-shaped plates 5, and node plates 6, make the three I-beams 2 more stable when connected to the sides and front of the steel beam 1. This, in turn, stabilizes the connection between the multiple wedge plates 3 and the steel beam 1 and the I-beams 2. Thus, the wedge plate reinforcement can disperse stress, reduce fatigue risk, and is convenient to construct, save construction time, improve node stiffness and ductility, and enhance structural safety.
