[0002] At present, with the rapid development of my country's economy, the mileage of transmission lines is increasing, and the number of transmission towers is also growing rapidly. As the service time of these towers increases, their angle steel rods gradually age. Especially in coastal areas, transmission lines are often affected by extreme weather such as typhoons, which accelerates the aging and failure of towers. The failure of angle steel is usually manifested as the buckling of the angle steel flank, which will cause damage to the transmission tower, causing the entire line to be out of power, causing huge economic losses to industrial and agricultural production and people's lives.

[0003] However, in order to prevent the failure of angle steel, reinforcement treatment is usually adopted in the prior art to extend the service life of the transmission tower. The commonly used reinforcement method is to use parallel components to reinforce the angle steel. In the specific operation, it is necessary to drill holes in the reinforced angle steel, and then connect the reinforcement plate to the angle steel with bolts. This method requires drilling holes on the two side wings of the angle steel respectively, which will cause damage to the original angle steel, that is, drilling holes will destroy the structural strength of the main material, making it difficult to ensure the reinforcement effect.
