What is the difference between I-beam and H-beam

Issuing time: 2018-05-16 11:18:57

字钢也称为 钢梁 (英文名称Universal Beam),是截面为工字形状的长条钢材。 I-beams, also known as steel beams (English name Universal Beam), are long steel bars with I-shaped cross sections. I-beams are divided into ordinary I-beams and light I-beams. 截面 形状为工字型的型钢 It is an I - shaped steel with a cross-sectional shape .

So what is the difference between I-beam H-beam

The flange of I-shaped steel is thicker on the web with a variable section and thinner on the outside; the flange of H-shaped steel is of constant section

HW is basically equal to the height of H-beam and flange width; it is mainly used for steel core columns in reinforced concrete frame structure columns, also known as stiff steel columns; it is mainly used for columns in steel structures

力荷载的框架结构中用做框架梁 HM is the ratio of the height of the H-beam to the width of the flange is approximately 1.33 ~~ 1.75. It is mainly used in steel structures: used as steel frame columns and used as frame beams in frame structures subjected to dynamic loads

HN is the ratio of the height of the H-beam to the flange width of 2 or more, which is mainly used for beams; the use of I-beams is equivalent to HN-beams.

1. Whether I-shaped steel is ordinary or light, because the cross-sectional dimensions are relatively high and narrow, the moments of inertia of the two main sleeves of the cross-section are greatly different. Therefore, they can only be used directly on the web Bending members in the plane or grouping them into lattice-type force members. It is not suitable to use axially-compressed components or components that are perpendicular to the web plane and also curved, which makes it very limited in application.

2. H-beams are highly efficient and economical cutting profiles. Due to the reasonable cross-sectional shape, they can make the steel perform better and improve cutting capacity. What is different from the ordinary I-shape is that the flange of the H-shaped steel is widened, and the inner and outer surfaces are usually parallel, so that it can be easily connected with high-strength screws and other components. Its size constitutes a reasonable series and complete model, which is convenient for design and selection.

3. The flanges of the h-shaped steel are all of equal thickness, and there are rolled sections, and there is also a combined section composed of 3 plates welded. I-beams are rolled sections. Due to the poor production process, the inside edge of the flange has a 1:10 slope. H-beam rolling is different from ordinary I-beams with only one set of horizontal rolls. Due to its wide flange and no slope, a set of vertical rolls must be added for simultaneous rolling. Therefore, its rolling process and equipment They are more complicated than ordinary rolling mills. The height of the largest rolled h-beam that can be produced in China is 800mm, which exceeds the welding cross section.
