Description

Technical Field

[0001] This utility model relates to the field of structural steel technology, and in particular to a lightweight angle steel. Background Technology

[0002] Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other, forming an angle. Angle steel can be used to form various load-bearing components according to different structural needs, and can also be used as connecting parts between components. It is widely used in various building structures and engineering structures, such as roof beams, bridges, transmission towers, lifting and transport machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, busbar support installations, and warehouse shelves. Existing angle steel has flat inner and outer sides on its legs; this application provides an angle steel with a ridge, which uses less material while maintaining the same strength. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a lightweight angle steel in response to the above-mentioned technical deficiencies.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a lightweight angle steel, including two mutually perpendicular legs, with a ridge provided on the legs, the two sides of the ridge being recessed into and protruding from the two sides of the legs respectively, and the ridge continuously approaching and moving away from the edge of the legs from one end to the other along the length direction of the angle steel.

[0005] To further optimize this technical solution, the extension direction of the ridge is sinusoidal.

[0006] To further optimize this technical solution, a groove is provided on the side of the leg.

[0007] To further optimize this technical solution, the cross-section of the groove is an isosceles triangle.

[0008] Compared with the prior art, the present invention has the following advantages: the leg is provided with a ridge, the two sides of the ridge are respectively recessed into and protruded from the two sides of the leg, and the ridge continuously approaches and moves away from the edge of the leg from one end to the other along the length of the angle steel, thereby reducing the thickness of the leg compared with the angle steel of the prior art while maintaining the same bending strength, and thus reducing the weight of the angle steel.

[0012] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] Detailed implementation method: combined with Figure 1-2 As shown, a lightweight angle steel includes two mutually perpendicular legs 1. Each leg 1 has a ridge 11, with one side of the ridge 11 recessed into and the other protruding from the sides of the leg 1. Specifically, one side of the ridge 11 may be recessed into the inner side of the leg 1 and protruding from the outer side, or one side may be recessed into the outer side of the leg 1 and protruding from the inner side (not shown in the figure). Preferably, the volume of the recessed portion of the ridge 11 is equal to the volume of the protruding portion. When the thickness of the leg 1 is 3 mm, the ridge 11 protrudes from the leg 1 by 0.5-1 mm. The ridge 11 moves closer to and further away from the edge of the leg 1 along the length of the angle steel from one end to the other. The presence of the ridge 11 increases the bending strength of the leg 1, thereby reducing the thickness of the leg 1 compared to existing angle steels while maintaining the same bending strength, thus reducing the weight of the angle steel and saving material.

[0014] Furthermore, the extension direction of the ridge 11 is sinusoidal, or it can be a broken line, but it is preferably sinusoidal.

[0015] Furthermore, the side of the leg 1 is provided with a groove 12. The presence of the groove 12 reduces the weight and saves materials without significantly reducing the bending strength of the edge of the leg 1.

[0016] Furthermore, the cross-section of the groove 12 is an isosceles triangle, and the isosceles triangle is symmetrical about the midpoint of the thickness direction of the leg 1.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
