Description

Technical Field

[0001] The utility model relates to the technical field of angle steels, in particular to an anti-corrosion structure of angle steels. Background Art

[0002] Angle steel, also known as angled joint sheet or angle iron, is a long steel strip with two perpendicular sides forming an angle. It can be divided into equal-leg angles and unequal-leg angles. Equal-leg angles have two sides of equal width. Angle steel can be used to form various load-bearing components according to different structural requirements and can also serve as connectors between components. It is widely used in various building and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, and warehouses.

[0003] Angle steel is used in seawater structures such as bridges, which will cause corrosion. Seawater is extremely corrosive, especially angle steel in seawater, which has a very short lifespan. Conventional corrosion-resistant methods usually use spray painting and other methods to provide a dense corrosion-resistant layer on the outside of the angle steel. This method can improve the corrosion resistance of the angle steel to a certain extent, but it still cannot significantly improve the corrosion resistance of the angle steel. Utility Model Content

[0025] Specifically, the slider structure includes: a rotating seat 7 and a dovetail slider 8; the rotating seat 7 is mounted on the outside of the anode buckle 5, the dovetail slider 8 is connected to the rotating seat 7 through an axis, and the rotating seat 7 can rotate relative to the dovetail slider 8, and the slide rail structure includes: a dovetail slide rail 9 and a fixed base 10; the dovetail slide rail 9 is movably mounted on the outside of the dovetail slider 8, the fixed base 10 is installed on the lower wall of the dovetail slide rail 9, and the upper wall of the dovetail slider 8 is installed with a pull rope 12, and the slider structure can slide inside the slide rail structure, thereby facilitating the operator to replace the anode structure in seawater.

[0026] Working principle: When using the present invention, first install the fixed base 10 on the seabed, and at the same time install the dovetail slide 9 in the seawater, wherein the top of the dovetail slide 9 should be exposed to the seawater, and the dovetail slide 9 is made of corrosion-resistant non-metallic material. Then the operator installs the dovetail slider 8 inside the dovetail slide 9. At this time, the operator installs the wire terminal 3 on the wire seat 2 of the angle steel frame 1 through the nut. At this time, the angle steel frame 1 and the sacrificial zinc rod 6 form a primary battery. At this time, the sacrificial anode cathodic protection method is adopted. When the seawater is strong against the angle steel frame 1 is corroded, and the sacrificial zinc rod 6 is corroded. The ammeter 11 can detect the current inside the conductor body 4. When there is no current inside the conductor body 4, the ammeter 11 has no reading. At this time, the operator pulls the conductor seat 2 by pulling the rope 12 to expose the dovetail slider 8 from the sea water. At this time, the operator rotates the rotating seat 7 180 degrees and removes the original sacrificial zinc rod 6 through the thread, replaces it with a new sacrificial zinc rod 6, and then replaces the sacrificial zinc rod 6 in the sea water, and can continue to protect the angle steel frame 1.
