Abstract

The invention discloses LC profile steel which comprises an inverted-L-shaped profile steel body, a first steel body and a second steel body. The first steel body and the second steel body are disposed at the top of the profile steel body and integrally connected with the top of the profile steel body. The first steel body is vertical to the top of the profile steel body. The included angle between the second steel body and the top of the profile steel body is smaller than 90 degrees, and the second steel body includes towards the first steel body. The invention further discloses a manufacturing method of the LC profile steel. The LC profile steel and the manufacturing method thereof have the advantages of high production efficiency, high steel strength, low energy consumption, low worker labor intensity, good work environment and environmental protection.

Description

technical field

[0001] The invention relates to the field of steel product manufacturing, in particular to an LC shaped steel and a manufacturing method thereof. Background technique

[0002] LC section steel is a section steel with special structure. Its structure is a combination of L-shaped structure and C-shaped structure in different directions. This complex structure also determines the complexity of its production process.

[0003] Traditional LC section steel is mainly produced by welding angle steel and flat steel in terms of production technology. The process is to roll the billet into angle steel, flat steel 1 and flat steel 2, and then cut and blank the material before welding. Sanding and straightening is the final step. This manufacturing process has the following disadvantages:

[0004] 1. Its production efficiency is low because it has many processes and the welding speed is limited by the on-site environment;

[0005] 2. The strength of the steel after fo...

Embodiment

[0058] Such as figure 1 As shown, a kind of LC section steel, it comprises the section steel main body 10 that is inverted L shape and the first steel body and the second steel body that are arranged at the top of section steel main body 10, and described first steel body 20, second steel body 30 are positioned at On the upper surface side of the top of the steel body 10, the first steel body 20 is perpendicular to the top of the steel body 10, and the angle θ1 between the second steel body 30 and the top of the steel body 10 is less than 90° and is inclined toward the first steel body 20. The first The steel body 20 and the second steel body 30 are integrally connected with the top of the shaped steel body 10 respectively.

[0059] In this embodiment, the cross-sectional edge k1 of the shaped steel main body 10 is in the shape of an arc protruding outward. The cross-sectional edge k2 of the second steel body 30 is in the shape of an arc protruding outward. The thickness of ...
