Beam of ordinary beam and light beam, H-beam three. Is a cross-sectional shape of the groove of the steel. Beam is divided into ordinary beam, light beam and H-beam three. Ordinary beam, light beam flange is tapered by the web portion thick outer thin; H-beam: HW HM HN HEA HEB HEM such as I-beam flanges are common, such as cross-section beam, light word Steel has become the national standard, ordinary 10 # I-beam is equivalent to I100 internationally (such as 10 # channel also equivalent channel U100) (because the standard implementation of the different countries, resulting in their specifications have subtle differences) H- also called wide-flange steel beam, HW HM HN from European standards, HEB is the German standard I-beam, which HW, HN beam has been widely used and produced in our country. HEA HEB HEM on many German design will see, in the domestic market is still difficult to buy. Steel works in the country, if you can use less steel welding and other specifications splicing. And large, it is usually considered the use of the mechanical properties comparable HW, HN steel instead. HW-steel reinforced concrete frame structure is mainly used for steel core columns in the column, also known as King of the steel columns; mainly used in steel column HM steel flange width and height ratio of roughly 1.33 ~ 1.75, mainly in steel used to make steel frame columns to withstand dynamic loads framework used to make the frame beam; example: device platform HN steel flange height and width ratio greater than or equal to 2; mainly for the use of the equivalent beam HN ordinary steel I-beam; ◆ whether the word is a common type of steel or light, because the cross-sectional dimensions are relatively high, narrow, so the cross-sectional moment of inertia of the two main sleeve big difference, therefore, generally only used directly in their web plane the flexural members will form a lattice or force its members. Of axial compression members or perpendicular to the plane of the web as well as curved elements are not adopted, which it has significant limitations on the scope of application. ◆ H-beam are efficient and economical cutting surface profiles (There are other cold-formed steel, pressure plate, etc.), as a reasonable cross-sectional shape, they can play the steel higher performance, improved load carrying capacity. Unlike ordinary is h-shaped steel flanges were widened, and the inner and outer surfaces generally parallel, so that makes it easy to connect with high strength bolts and other components. Constitute a series of reasonable size, model range, ease of design choice. Scope ordinary beam, light beam, due to the cross-sectional dimensions are relatively high, narrow, so the cross-sectional moment of inertia of the two main sleeve big difference, therefore, generally only used directly in their web plane the flexural members will form a lattice or force its members. Of axial compression members or perpendicular to the plane of the web as well as curved elements are not adopted, which it has significant limitations on the scope of application. The beam should be selected according to the requirements using the design drawings. Dimensions are efficient and economical design of H-beam steel cutting surface type (there are other cold-formed steel, pressure plate, etc.), as a reasonable cross-sectional shape, they can play the steel higher performance, improved CD bearing capacity. Unlike ordinary beam is H-beam flanges were widened, and the inner and outer surfaces generally parallel, so that makes it easy to connect with high-strength screw Gui and other components. Constitutes a reasonable size, model range, ease of design choice. In the I-beam structural design selection should be based on its mechanical properties, chemical properties, weldability, structure, size and other reasonable choice of beam for use. H-beam welding process, such as the thickness of the flange are there rolling cross-section, there are a combination of three plates welded cross-section composed. Ordinary beam cross section are rolling, because the production process is poor, inner flange edge has 1:10 slope. Unlike ordinary rolled H-section steel beam just a horizontal roll, because of its wide flange and no inclination (or slope is very small), and thus should be the creation of a set of vertical rolls simultaneously rolling, so its rolling mill technology and equipment than the ordinary complex. Domestic rolled H-beam to produce the maximum height of 800mm, exceeded only be welded composite section. H narrow flange beams or steel suitable for bending members, and wide flange h and h-beam steel pile is applicable to axial compression members or bending members. Ordinary beam, light beam compared with HW, HN steel, etc. under the weight of the premise, w, ix, iy not as H beam Qq number: 1622270635
