Abstract

The invention discloses angle steel which comprises an angle steel body; a groove is formed in one side of the angle steel body; a through hole is formed in the angle steel body; a protective layer is coated on the surface of the angle steel body; a carbon fiber layer and a fireproof layer are sequentially arranged on a position, inside the protective layer, at the inner side of the angle steel body from inside to outside; the protective layer comprises a copper coated layer and a zinc coated layer, which are sequentially arranged from outside to inside; and the fireproof layer comprises a polyethylene layer, a glass fiber layer and an asbestos layer. According to the angle steel disclosed by the invention, the protective layer is used, so that the angle steel is not corroded under a humid environment, and normal use of the angle steel is guaranteed; the fireproof layer is used, so that the angle steel body is not affected by a fire disaster when the fire disaster happens; meanwhile, greater economic loss due to heat conduction of the angle steel body is also voided; and the carbon fiber layer is used, so that the integral thermal expansion coefficient of the angle steel body is guaranteed, and use performances of the angle steel are improved.

Description

technical field [0001] The invention relates to the technical field of angle steel, in particular to an angle steel. Background technique [0002] As we all know, angle steel is a long strip of steel, which is widely used in the construction field, such as bridges, transmission towers, ships, industrial furnaces, warehouse shelves, container racks, etc. The raw material billet is a low-carbon square billet, which has a certain strength and toughness. According to the needs of construction, the shape is designed and manufactured into a certain geometric shape by means of hot rolling, normalizing, hot rolling, etc. through the mold process. [0003] The properties of the angle steel itself are light weight, low cost, simple structure, and easy assembly. The assembly method can be adjusted arbitrarily according to the needs of the space. Therefore, the shelf structure built by the angle steel structure is widely used, and the angle steel structure can be applied in different en...
