Description

Technical Field

[0001] This utility model belongs to the field of steel structure building technology, and in particular relates to a fixing component between H-beams and steel columns. Background Technology

[0002] H-beams are connected to steel columns via welding, high-strength bolts, or end plates to form rigid / semi-rigid joints, widely used in industrial plants, high-rise buildings, and large-span spatial frames. Their advantages are significant: ① High load-bearing capacity: The wide-flange design of H-beams combined with rigid joints efficiently transfers bending moment and shear force, supporting heavy loads; ② Convenient construction: Bolted connections facilitate modular prefabrication and rapid on-site assembly, while welded joints enhance overall integrity and adapt to complex stresses; ③ Space economy: Compact cross-sections reduce the impact on building height, optimizing space utilization; ④ Seismic advantages: Strengthening joints through stiffening ribs, extended flanges, or dog-bone weakening designs achieves a "strong column, weak beam" effect, guiding the formation of plastic hinges and improving the structure's energy dissipation capacity.

[0003] After the H-beams are fixed to the steel columns, they can jointly bear the loads of the structure, making the entire steel structure system a stable whole. In order to ensure the safety of the building, we need to design a fixing component between the H-beams and the steel columns, using a reinforcement structure and a support structure. The web flange reinforcement structure can increase the effective cross-sectional area of ​​the connection between the H-beams and the steel columns, enabling it to withstand greater axial force, bending moment and shear force. The reinforcement structure can restrain the deformation of the H-beams and steel columns under stress, limit their relative displacement, improve the stability of the connection node and the overall structure, provide a stable support foundation, and enhance the vertical bearing capacity of the connection node. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing component between H-beams and steel columns, which has the advantages of enabling it to withstand greater axial force, bending moment and shear force, the reinforcement structure can constrain the deformation of H-beams and steel columns under stress, limit their relative displacement, improve the stability of the connection node and the overall structure, provide a stable supporting foundation, and enhance the vertical bearing capacity of the connection node, so as to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A fixing component between an H-beam and a steel column includes a steel column. Two symmetrical H-beams are arranged at the central axis on both sides of the steel column. Two symmetrical node plates are fixedly connected to both sides of the steel column. Two symmetrical connecting plates are fixedly connected to the opposite side of the two node plates. The two connecting plates are fixedly connected to the H-beams by bolts. A seven-shaped plate is fixedly connected to the opposite side of the bottom of the two H-beams by bolts. An L-shaped plate is arranged at the bottom of both sides of the steel column. A connecting plate is fixedly connected to the opposite side of the two seven-shaped plates. A fixing plate is fixedly connected to the opposite side of the two L-shaped plates. A diagonal rod is fixedly connected to the opposite side of the connecting plate and the fixing plate by bolts. A lower base plate is fixedly connected to the bottom of the H-beam by bolts. A vertical support rod is fixedly connected to the bottom of the lower base plate. The vertical support rod is fixedly connected to the diagonal rod.

[0006] Preferably, the H-beam is provided with four reinforcing plates at both the top and bottom, and the reinforcing plates are fixedly connected to the left and right sides of the steel column.

[0007] Preferably, T-plates are provided at the top and bottom of the two node plates, and the four T-plates are fixedly connected to the steel column on opposite sides.

[0008] Preferably, four angle steels are fixedly connected to the left and right sides of the two T-plates by bolts, and the opposite sides of the four angle steels are fixedly connected to the steel column by bolts.

[0009] Preferably, a triangular plate is fixedly connected to the bottom of each of the two H-beams, and the opposite side of the triangular plate is fixedly connected to a T-plate. A diagonal brace is fixedly connected to the surface of the triangular plate by bolts, and the end of the diagonal brace away from the triangular plate is fixedly connected to a vertical support rod.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model fixes two H-beams using node plates and connecting clamps. Through the combined use of seven-shaped plates, diagonal braces, and triangular plates, the two vertical support rods support the bottom of the H-beams, ensuring the structural stability of the connection between the two H-beams and the steel column. This allows the H-beams to withstand greater axial force, bending moment, and shear force. The reinforced structure can constrain the deformation of the H-beams and steel columns under stress, limit their relative displacement, improve the stability of the connection node and the overall structure, provide a stable support foundation, and enhance the vertical bearing capacity of the connection node.

[0012] 2. By setting up a reinforcing plate, the flange plate of the steel column plays an important role in the structure. Increasing the thickness of the steel column can directly improve its load-bearing capacity, enabling it to withstand greater loads and reduce deformation and stress concentration caused by loads, thereby improving the strength and stability of the structure when the steel column and the two H-beams are connected.

[0013] 3. By using T-shaped plates, the cross-shaped section formed by the two T-shaped plates increases the moment of inertia and bending stiffness of the steel column. When subjected to axial pressure and bending moment, it can reduce the deformation of the steel column and improve the stability of the column, thus enabling it to withstand greater loads. This high stiffness characteristic reduces structural damage and safety hazards caused by excessive deformation in the structure reinforced by the two T-shaped plates during long-term use.

[0022] In the following description, embodiments of the fixing member between the H-beam and the steel column of this utility model will be described with reference to the accompanying drawings.

[0023] Figure 1-5This invention illustrates a fixing component between an H-beam and a steel column according to an embodiment of the present invention. It includes a steel column 1, with two symmetrical H-beams 2 positioned along the central axis on both sides of the steel column 1. Four reinforcing plates 3 are provided at the top and bottom of each H-beam 2. The reinforcing plates 3 are fixedly connected to the left and right sides of the steel column 1. Through the reinforcement plates 3, the flanges of the steel column 1 bear significant load-bearing responsibility in the structure. Increasing the thickness of the steel column 1 directly improves its load-bearing capacity, enabling it to withstand greater loads and reducing deformation and stress concentration caused by loads, thereby improving the structural integrity of the steel column 1 and the two H-beams 2. To enhance the strength and stability of the structure during connection, two symmetrical node plates 6 are fixedly connected to both sides of the steel column 1. T-plates 4 are installed at the top and bottom of each node plate 6. The four T-plates 4 are fixedly connected to the steel column 1 on opposite sides. The cross-shaped section formed by the two T-plates 4 increases the moment of inertia and bending stiffness of the steel column 1. Under axial pressure and bending moment, this reduces the deformation of the steel column 1, improves its stability, and allows it to withstand greater loads. This high stiffness characteristic ensures the structure reinforced with the two T-plates 4 can withstand long-term use. To reduce structural damage and safety hazards caused by excessive deformation, four angle steels 5 are bolted to the left and right sides of the two T-shaped plates 4. The facing sides of the four angle steels 5 are bolted to the steel column 1. Two symmetrical connecting plates 7 are bolted to the facing sides of the two node plates 6. The two connecting plates 7 are bolted to the H-beams 2. The bottom sides of the two H-beams 2 are bolted to the opposite sides of the bottom of the two H-beams 2. L-shaped plates 9 are set at the bottom of the left and right sides of the steel column 1. Connecting plates 10 are bolted to the facing sides of the two L-shaped plates 8. A fixing plate 11 is fixedly connected to one side of each H-beam 2. A diagonal rod 12 is fixedly connected to the side of the connecting plate 10 facing the fixing plate 11 by bolts. A lower base plate 13 is fixedly connected to the bottom of the lower base plate 13. A vertical support rod 14 is fixedly connected to the bottom of the lower base plate 13. The vertical support rod 14 is fixedly connected to the diagonal rod 12. A triangular plate 15 is fixedly connected to the bottom of each of the two H-beams 2. The side of the triangular plate 15 facing each other is fixedly connected to the T-plate 4. A diagonal brace 16 is fixedly connected to the surface of the triangular plate 15 by bolts. The end of the diagonal brace 16 away from the triangular plate 15 is fixedly connected to the vertical support rod 14.

[0024] Working principle: When using this utility model, the user reinforces the web and flange of the steel column 1 with reinforcing plate 3 and T-plate 4, making the support point more stable when the steel column 1 and H-beam 2 are connected. The two node plates 6 reinforce the upper and lower sides of the H-beam 2, ensuring a stable connection between the two H-beams 2 on both sides of the steel column 1. Then, the two connecting clamps 7 are fixed to the front and rear of the H-beam 2 with bolts, stabilizing the connection node. Finally, the two hexagonal plates 8 are fixed to the bottom of the H-beam 2 with bolts. Then, two L-shaped plates 9 are fixed on both sides of the T-shaped plate 4, and two hexagonal plates 8 are fixed to the L-shaped plates 9. The two ends of the diagonal rod 12 are fixed to the surface of the fixing plate 11 by bolts. The diagonal rod 12 supports and fixes the two ends of the bottom of the H-shaped steel 2. The bottom plate 13 and the vertical support rod 14 reinforce and support the top of the diagonal rod 12. At the same time, the triangular plate 15 and the diagonal brace 16 support and reinforce the node between the steel column 1 and the H-shaped steel 2 and the vertical support rod 14. Finally, the connection between the steel column 1 and the H-shaped steel 2 is fixed.

[0025] In summary, the fixing components between the H-beams and the steel columns use node plates 6 and connecting clamps 7 to secure the two H-beams 2. The combined use of the seven-shaped plate 8, diagonal brace 12, and triangular plate 15 ensures that the two vertical support rods 14 support the bottom of the H-beams 2, guaranteeing the structural stability of the connection between the two H-beams 2 and the steel column 1. This allows the H-beams 2 to withstand greater axial forces, bending moments, and shear forces. The reinforced structure constrains the deformation of the H-beams and steel columns under stress, limits their relative displacement, improves the stability of the connection node and the overall structure, provides a stable supporting foundation, and enhances the vertical bearing capacity of the connection node.
