Description

Technical Field

[0001] The utility model belongs to the technical field of hot-rolled U-shaped steel, and more specifically, particularly relates to high-precision hot-rolled U-shaped steel. Background Art

[0002] U-shaped steel refers to steel with a U-shaped cross section, also known as U-shaped channel steel. It is a commonly used structural steel, widely used in construction, machinery, highway bridges and other fields. The cross-section of U-shaped steel is U-shaped, with flange widths of different widths on the upper and lower sides. The wider side of the flange is called the upper flange, the narrower side of the flange is called the lower flange, and the part between the two flanges is called the web. The length of U-shaped steel is generally 6 meters to 12 meters, and it can be cut and welded as needed.

[0003] Based on the above, the inventors have found the following problems: the existing hot-rolled U-shaped steel is used directly during use, but when the installation object is large or some special installation positions cause high pressure, it may cause deformation of both sides of the U-shaped steel, which will cause unnecessary trouble to the staff and indirectly reduce the efficiency of use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a high-precision hot-rolled U-shaped steel is provided to achieve a purpose with greater practical value. Utility Model Content

[0005] The purpose and effect of the high-precision hot-rolled U-shaped steel of the utility model are achieved by the following specific technical means:

[0006] A high-precision hot-rolled U-shaped steel comprises a bottom plate, a group of protective edges are welded to the top of the bottom plate, a reinforcement piece is fixedly installed on the top of the bottom plate, and one end of the reinforcement piece away from the bottom plate is fixedly connected to the protective edge.

[0007] Furthermore, an anti-rust layer is provided on the inner wall of the bottom plate, and the material of the anti-rust layer is set to be a phosphate layer material.

[0008] Furthermore, the outer wall surface of the bottom plate is provided with a paint layer.

[0009] Furthermore, the material of the reinforcement is set to be alloy steel.

[0010] Furthermore, both ends of the reinforcement member are fixed to the bottom plate and the protective edge by welding.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] Through the design of the anti-rust layer, the anti-rust performance of the U-shaped steel can be effectively increased, avoiding surface rust when placed for a long time, thereby reducing the service life, and indirectly improving the use efficiency of the U-shaped steel.

[0013] The design of the paint layer can provide a certain degree of anti-corrosion and aesthetic effects. Workers can choose different colors of paint according to different usage scenarios. At the same time, the anti-corrosion performance is increased, which indirectly brings convenience to the staff.

[0014] Through the design of the reinforcement piece, the U-shaped steel can be effectively reinforced during its installation and use to avoid deformation of the protective edge caused by pressure, thereby indirectly increasing the stability of the U-shaped steel and making it stronger.
