Description

Technical Field

[0001] This utility model relates to the field of angle steel tower technology, and more specifically, to a coastal reinforced angle steel corrosion-resistant tower. Background Technology

[0002] With the rapid development of the power grid, the demand for transmission angle steel towers is also increasing. The operation and maintenance costs of transmission towers due to steel corrosion are staggering. The atmospheric environment (coastal salt spray and chemical acid rain areas) causes severe corrosion of conventional transmission angle steel towers. It can be seen that the corrosion of angle steel towers causes a great waste of transmission tower materials and energy, and seriously affects the safety and reliability of power grid operation. Therefore, it is necessary to provide a coastal reinforced angle steel corrosion-resistant tower to prevent the loss of strength caused by corrosion of transmission angle steel towers.

The tower body includes an angle steel main body, which includes a base steel. The surface of the base steel is provided with a galvanized layer, and the surface of the galvanized layer is provided with a corrosion-resistant mechanism. The corrosion-resistant mechanism includes a zinc-rich primer, a polyurethane topcoat, and an epoxy powder coating.

A base plate is fixedly connected to the side of the reinforcing base, and a fixing hole is provided at the top of the base plate. A fixing bolt is installed inside the fixing hole.

[0007] When using this technical solution for coastal reinforced angle steel corrosion-resistant towers, a zinc coating is formed by hot-dip galvanizing the surface of the base steel. Simultaneously, the corrosion resistance of the angle steel body is improved by the action of zinc-rich primer, polyurethane topcoat, and epoxy powder, and by setting a polyethylene layer at the corners of the angle steel body, thus improving the corrosion resistance of the angle steel tower.

[0008] Furthermore, a polyethylene layer is provided at the corner of the base steel.

[0012] (3) Beneficial effects

[0013] In summary, this utility model has the following beneficial effects:

[0014] This coastal reinforced angle steel corrosion-resistant tower improves the corrosion resistance of the angle steel body by applying a galvanized layer, a zinc-rich primer, a polyurethane topcoat, and epoxy powder. The galvanized layer is formed by hot-dip galvanizing the base steel surface. The zinc-rich primer, polyurethane topcoat, and epoxy powder, along with the polyethylene layer at the corners of the angle steel body, enhance the corrosion resistance of the tower.
