Abstract

The invention relates to a buckling-restrained reinforcing device for power transmission iron tower angle steel. The reinforcing device comprises an external connector, an internal connecting pre-tightening outer part, an internal connecting pre-tightening inner part, an internal connector and a first bolt, wherein the external connector comprises a first steel plate and a second steel plate; oneend of the first steel plate is hinged with the internal connecting pre-tightening outer part, and the other end of the first steel plate and one end of the second steel plate are in L-shaped connection; the other end of the second steel plate is hinged with the internal connecting pre-tightening inner part; the internal connecting pre-tightening outer part and the internal connecting pre-tightening inner part are locked by the first bolt; the external connector is arranged at the outer side of the power transmission iron tower angle steel; the internal connector is arranged at the inner sideof the power transmission iron tower angle steel; and the internal connecting pre-tightening outer part and the internal connecting pre-tightening inner part lock the internal connector to the inner side of the power transmission iron tower angle steel through the first bolt, so that reinforcing of the power transmission iron tower angle steel is realized. The buckling-restrained reinforcing device for power transmission iron tower angle steel can effectively improve the buckling-restrained reinforcing effect of the power transmission iron tower angle steel.

Description

technical field [0001] The invention relates to the field of steel tower reinforcement devices, and more particularly relates to an anti-buckling reinforcement device for power transmission tower angle steel. Background technique [0002] With the rapid development of my country's economy, the mileage of transmission lines continues to increase, and the base of transmission towers continues to increase. With the increase of the service time of the transmission tower, its angle steel rods are constantly aging. When the transmission line is affected by extreme weather such as typhoons in coastal areas, the transmission tower will be damaged due to the failure of the angle steel (mostly buckling), and even the entire The power outage of three lines will bring great economic losses to industrial and agricultural production and people's lives. Therefore, designing a transmission tower angle steel reinforcement device that is safe, reliable and convenient for construction is of g...
