Description

Technical Field

[0001] The utility model relates to the technical field of transmission line tower reinforcement, and particularly relates to a reinforcement structure for a transmission line tower. Background Technique

[0002] A transmission line tower is a tower-shaped building used for power transmission. Its structural feature is that various tower types belong to space truss structures, and the members are mainly composed of single equal-angle steel or combined angle steel. Generally, two materials, Q235 (A3F) and Q345 (16Mn), are used. The connection between members adopts rough bolts, and the connection is achieved by the bolts bearing shear force. The whole tower is composed of angle steel, connecting steel plates and bolts. Individual components such as tower feet are welded by several steel plates into a combined component. Therefore, hot-dip galvanized anti-corrosion, transportation and construction erection are extremely convenient. For towers with a height below 60m, foot studs are set on one of the main members of the tower to facilitate tower climbing by construction workers.

[0003] The current tower foundation mainly uses vertical columns. However, in some areas, there are strong wind and bad weather. The vertical columns in areas with strong winds are prone to cause the columns to shift and tilt, driving the tower to shift and tilt, posing a hidden danger to the use of the transmission line tower, prone to the inclination of the transmission line tower, and in severe cases, leading to the collapse accident of the transmission line tower. To solve the above problems, a reinforcement structure for a transmission line tower is proposed to solve the above problems. Content of the Utility Model
