technical field

The utility model relates to the technical field of H-shaped steel, in particular to a high-strength impact-resistant H-shaped steel column.

Background technique

H-beam is an economical section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross section is the same as the English letter "H". Since all parts of H-beam are arranged at right angles, so H Profile steel has the advantages of strong bending resistance, simple construction, cost saving and light weight in all directions, and has been widely used. Named as parallel flange I-beam, the web thickness of H-beam is smaller than that of ordinary I-beam with the same height of the web, and the flange width is larger than that of ordinary I-beam with the same height of the web, so it is also named wide flange The shape of the beam is determined by the shape. The section modulus, moment of inertia and corresponding strength of the H-beam are obviously better than the ordinary I-beam of the same single weight.
