Abstract

The invention discloses a weather-resistant angle steel for transmission tower. The weather-resistant angle steel comprises a weather-resistant angle steel body and a plurality of round grooves, the weather-resistant angle steel body is formed by sequentially connecting a plurality of V-shaped units, each V-shaped unit is composed of two steel plates, wherein a first included angle is formed at the joint of the two steel plates, and a second included angle is formed at the joint of every two adjacent V-shaped units; and the plurality of round grooves are formed in the surface of the steel plate body, and anti-corrosion blocks are installed in the round grooves and fixedly connected with the round grooves through adhesives. By means of the mode, the weather-resistant angle steel for the transmission tower can solve the problems of material waste, maintenance cost increase, environment pollution and the like caused by galvanizing corrosion prevention in the manufacturing process of the transmission tower.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to weather-resistant angle steel for power transmission towers. Background technique [0002] For a long time, my country's transmission line towers have mainly used hot-rolled angle steel profiles, supplemented by a small amount of steel pipes as tower materials. The types of steel materials are mainly Q235 and Q345. It has been widely used in transmission line towers, and the application of high-strength bolts, cold-formed steel, weathering steel and composite materials has also entered the stage of gradual exploration and use. [0003] In the manufacturing process of transmission towers made of carbon steel and low-alloy structural steel, hot-dip galvanizing is used for anti-corrosion. With the continuous improvement of the power grid construction level and new transmission technologies such as multi-circuit on the same tower, compact lines, and multi-split large-section wires The appli...
