Description

Technical Field

[0001] This utility model relates to the field of power transmission tower steel structure technology, specifically to a reinforcement structure for power transmission tower steel components. Background Technology

[0002] Steel components of power transmission towers, as the core parts of the tower structure, mainly include angle steel, steel pipes, and H-beams. These components, through scientific combination and reliable connection, construct a robust framework system to support high-voltage transmission lines. Among them, H-beams, due to their high bending stiffness and load-bearing capacity, are often used in main beams or supporting structures to withstand large bending moments and shear forces. For example, they are used in the main beams or supporting structures of towers spanning complex terrains such as rivers and canyons to meet the stringent requirements of complex stress environments.

[0003] In existing applications, H-beams, due to their relatively thin webs, are prone to local buckling under heavy loads. Furthermore, compared to closed-section steel pipes, H-beams have lower torsional stiffness, potentially leading to greater structural deformation under torque, thus affecting overall structural stability. Therefore, we propose a reinforcement structure for power transmission tower steel components to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a reinforcement structure for steel components of power transmission towers, in order to solve the problems mentioned in the background art. In the application of existing H-beams, due to the relatively thin web of H-beams, the web is prone to local buckling when subjected to large loads. Moreover, compared with steel pipes with closed sections, H-beams have lower torsional stiffness, and the structural deformation may be larger when subjected to torque, thus affecting the overall stability of the structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A steel component reinforcement structure for power transmission towers includes a vertical connecting plate, a top plate horizontally arranged on one side of the vertical connecting plate, an arc-shaped connecting plate vertically arranged on the other end of the top plate, two vertical reinforcing plates symmetrically and evenly spaced on the upper and lower sides of the top plate, a curved reinforcing plate arranged on the other side of the arc-shaped connecting plate, and two horizontal connecting plates symmetrically arranged at the upper and lower ends of the curved reinforcing plate.

[0007] The bending reinforcement plate bends from both sides toward the center near the arc-shaped connecting plate. Multiple mounting holes are symmetrically and evenly spaced on the upper and lower sides of the bending reinforcement plate, and the side projection of the bending reinforcement plate is arc-shaped.

[0008] Furthermore, the vertical connecting plate is provided with multiple waist-shaped holes symmetrically and evenly spaced on both the upper and lower sides.

[0009] Furthermore, one end of the top plate is fixedly connected to the vertical connecting plate, and the other end of the top plate is fixedly connected to the arc-shaped connecting plate.

[0010] Furthermore, the arc-shaped connecting plate has an arc surface on the side away from the top plate, and the arc-shaped connecting plate is fixedly connected to the bending reinforcing plate through the arc surface.

[0011] Furthermore, the plurality of mounting holes are respectively aligned with the plurality of waist-shaped holes, the two ends of the plurality of vertical reinforcing plates are respectively fixedly connected to the vertical connecting plate and the arc-shaped connecting plate, the bottom of the vertical reinforcing plate is fixedly connected to the top plate, and the plurality of vertical reinforcing plates are respectively spaced apart from the plurality of waist-shaped holes.

[0012] Furthermore, the two horizontal connecting plates are fixedly connected to the upper and lower ends of the bending reinforcing plate, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model fixes two horizontal connecting plates to the two flanges at the upper and lower ends of the H-beam respectively, and then connects the two horizontal connecting plates with a bent reinforcing plate. This allows the two forces on the H-beam to be transferred through the top plate on the other side of the arc-shaped connecting plate to the web of the H-beam connected to the vertical connecting plate, thereby improving the torsional stiffness of the H-beam. Furthermore, by installing the plate on the open sections on both sides of the H-beam, it can hold the web on both sides, preventing web deformation and improving structural strength.

[0015] 2. This utility model, through multiple vertical reinforcing plates set on the top plate, can further enhance the structural strength of the vertical connecting plate, the top plate, and the arc-shaped connecting plate, ensuring the overall stability of the structure.

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.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a steel component reinforcement structure for power transmission towers, including a vertical connecting plate 1, a top plate 2 horizontally arranged on one side of the vertical connecting plate 1, an arc-shaped connecting plate 3 vertically arranged on the other end of the top plate 2, two vertical reinforcing plates 4 symmetrically and evenly spaced on the upper and lower sides of the top plate 2, a curved reinforcing plate 5 arranged on the other side of the arc-shaped connecting plate 3, and two horizontal connecting plates 6 symmetrically arranged at the upper and lower ends of the curved reinforcing plate 5.

[0023] The bending reinforcement plate 5 bends from both sides toward the center near the arc-shaped connecting plate 3. Multiple mounting holes 501 are symmetrically and evenly spaced on the upper and lower sides of the bending reinforcement plate 5. The side projection of the bending reinforcement plate 5 is arc-shaped.

[0024] The vertical connecting plate 1 has multiple oblong holes 101 symmetrically and evenly spaced on its upper and lower sides. In this example, by setting multiple oblong holes 101, it is easy to fix the vertical connecting plate 1 to the web of the H-beam, thereby strengthening the H-beam structure.

[0025] One end of the top plate 2 is fixedly connected to the vertical connecting plate 1, and the other end of the top plate 2 is fixedly connected to the arc-shaped connecting plate 3.

[0026] The curved connecting plate 3 has an arc surface 301 on the side away from the top plate 2, and the curved connecting plate 3 is fixedly connected to the curved reinforcing plate 5 through the arc surface 301. In this example, by setting the arc surface 301, the curved surface of the curved connecting plate 3 and the curved reinforcing plate 5 can fit more closely, ensuring force transmission and improving structural strength.

[0027] Multiple mounting holes 501 are respectively aligned with multiple oblong holes 101. Multiple vertical reinforcing plates 4 are fixedly connected at both ends to the vertical connecting plate 1 and the arc-shaped connecting plate 3, respectively. The bottom of the vertical reinforcing plates 4 is fixedly connected to the top plate 2, and the multiple vertical reinforcing plates 4 are spaced apart from the multiple oblong holes 101. In this example, by providing multiple mounting holes 501, bolts can be easily inserted into the multiple oblong holes 101 through the mounting holes 501, thereby fixing the vertical connecting plate 1 to the web of the H-beam.

[0028] The two horizontal connecting plates 6 are fixedly connected to the upper and lower ends of the curved reinforcing plate 5, respectively.

[0029] Working principle: By passing bolts through mounting holes 501 and slotted holes 101, the vertical connecting plate 1 is fixed to one side of the web of the H-beam. Then, the two horizontal connecting plates 6 are fixed to the inner sides of the two flanges at the top and bottom ends of the H-beam, respectively. When the flanges of the H-beam are under pressure, the force is transferred to the bending reinforcing plate 5 through the two horizontal connecting plates 6. Then, through the bending structure of the bending reinforcing plate 5, the force is transferred through the arc-shaped connecting plate 3 to the top plate 2 and the vertical connecting plate 1 at the other end of the multiple vertical reinforcing plates 4. Finally, the force is transferred to the web of the H-beam through the vertical connecting plate 1, making the H-beam structure more stable and able to withstand greater loads.
