SUMMARY

[0004] The utility model solves the above-mentioned prior art problems, provides a kind of corrosion-resistant steel columns, reach the purposes of convenient spraying and improve corrosion protection effect.

[0005] The utility model solves its technical problem and adopts the technical scheme: this corrosion-resistant steel column, including steel column and metal plating, the surface of steel column is equipped with metal plating, the surface of steel column is symmetrically opened with inclined plane, the surface of metal plating is coated with rustproof protective layer, the surface of steel column is opened with through-hole.

[0006] To further improve, the metal plating is zinc, and the rustproof protective layer is epoxy resin.

[0007] Further improvement, the steel column is H-shaped steel, the inner wall of the steel column is respectively attached to a plurality of blocks, and the blocks are connected to the bolts in sliding mode through the through holes formed on the surfaces.

[0008] Further improvement, one end of the bolt penetrates the block and is connected to the steel column in threaded mode, and a plurality of threaded holes are formed on the surface of the steel column.

[0009] The utility model has the advantages that: the utility model, through the cooperation of the inclined surface and the steel column, after the steel column is processed, the surface of the steel column is first subjected to galvanizing operation, a metal plating layer is formed, zinc is relatively stable in dry air and is not prone to discoloration, in water and humid atmosphere, it reacts with oxygen or carbon dioxide to form an oxide or a basic zinc carbonate film, which can prevent zinc from continuing to be plated with an oxide, plays a protective role, the surface of the metal plating layer is then subjected to epoxy resin smearing, a rustproof protective layer is formed, the rustproof protective layer can play a certain protective role on the metal plating layer during carrying, simultaneously plays the roles of impact resistance, anti-peeling and electrical insulation, through the double protection mode, it can effectively avoid damage to the corrosion-resistant structure during carrying, guarantees the corrosion-resistant effect, meanwhile, the device has fewer gaps, so that the device is more convenient to spray.

[0016] The utility model will be further described below in combination with the drawings:

[0017] Refer to the drawings Figures 1-5 ​​​​In the embodiment, a kind of corrosion-resistant steel column, including steel column 1 and metal plating 2, the surface of steel column 1 is equipped with metal plating 2, the surface of steel column 1 is symmetrically opened with inclined plane 4, inclined plane 4 can make the surface of steel column 1 more flat, reduce the angle of the corner of steel column 1 surface, so that it can be more convenient when spraying, the surface of metal plating 2 is coated with rust-proof protective layer 3, metal plating 2 is zinc, rust-proof protective layer 3 is epoxy resin, the surface of steel column 1 is opened with through hole 6, through hole 6 can reduce weight while saving cost, steel column 1 is H-shaped steel, the inner wall of steel column 1 is respectively attached with multiple blocks 5, block 5 is slidably connected with bolt 7 by the through hole on the surface, one end of bolt 7 penetrates block 5 and is threadedly connected with steel column 1, multiple threaded holes are formed on the surface of steel column 1.

[0018] Working principle:

[0019] When the steel column is used:

[0020] After steel column 1 is processed, first, the surface of steel column 1 is galvanized to form metal plating 2, zinc is relatively stable in dry air, not easy to discolor, in water and humid atmosphere, oxide or basic zinc carbonate film is formed by the action of oxygen or carbon dioxide, which can prevent zinc from continuing to be oxidized, and plays a protective role, then the surface of metal plating 2 is coated with epoxy resin to form rust-proof protective layer 3, rust-proof protective layer 3 can protect metal plating 2 during handling, while playing the roles of impact resistance, anti-peeling and electrical insulation, etc., after the anticorrosion work is completed, block 5 is placed in the interior of steel column 1, and bolt 7 is corresponded with the threaded hole on the surface of steel column 1, bolt 7 is threadedly connected with the threaded hole on the surface of steel column 1 by rotating, so that the position of block 5 is fixed, and the supporting effect of steel column 1 is played, and the strength of steel column 1 is improved.
