Ordinary beam, light beam flange is variable section by a thick web portion, the outer thin; H-beam: HW HM HN HEA HEB HEM and other beam flange is equal section ordinary beam, light word Steel has become the national standard, ordinary 10 # I-beam is equivalent to I100 internationally (such as 10 # channel also corresponds to channel U100) (because the standard implementation of the different countries, resulting in their specifications have subtle differences) H Type also called wide-flange beam beam, HW HM HN from the European standard, HEB German standard I-beam, which HW, HN beam has been widely used and produced in our country. HEA HEB HEM in many German plan would see, in the domestic market is still difficult to buy. In the domestic steel works, if you can use less steel and other specifications for welding splicing. And large, then, consider the use of the mechanical properties generally comparable HW, HN steel instead. HW beam is mainly used for reinforced concrete frame structure column steel core columns, also known as King of the steel column; mainly used in steel column HM steel flange height and width ratio of roughly 1.33 ~ 1.75, mainly in steel used to make steel frame columns to withstand dynamic loads to do frame by frame beam; for example: device platform HN steel flange height and width ratio is greater than or equal to 2; the main purposes for the ordinary beam girder steel equivalent HN; ◆ work word steel, whether ordinary or light, because cross-sectional dimensions are relatively high, narrow, so the cross-sectional moment of inertia of the two spindles large difference, it can only be used directly in its web plane Bending The member or its composition lattice force member. For axial compression members or perpendicular to the plane of the web as well as curved components are not suitable, which it has significant limitations on the scope of application. ◆ H-beam cutting surface profile belongs to efficiently and economically (there are other cold-formed thin-walled steel, pressure plate, etc.), due to a reasonable cross-sectional shape, they can make steel more play performance, improve the carrying capacity. Unlike ordinary it is h-shaped steel flange was widened, and the inner and outer surfaces generally parallel, so that makes it easy to connect with high-strength bolts and other components. Constitute series reasonable size, complete model, ease of design choice.

The use of beam shall be chosen according to the requirements of design drawings. Sized H-beam cutting plane belonging to efficient and economical type of steel (Others are cold-formed thin-walled steel, pressure plate, etc.), due to a reasonable cross-sectional shape, they can make steel more play to the effectiveness and improve the bearing capacity of the CD. Unlike ordinary beam it is H-beam flanges were widened, and inner and outer surfaces generally parallel, so that makes it easy to connect with high-strength bolts and other components. Constitutes a reasonable size, complete model, ease of design choice. In the structural design of the beam selection should be based on its mechanical properties, chemical properties, weldability, structure, size and other reasonable choice of beam for use. H-beam flange welding process are of equal thickness, there are rolling cross-section, but also by the composite section consisting of three plate welding. Ordinary beam are rolling cross-section, because the production process is poor, inner flange side have 1:10 slope. Rolled H-shaped steel beam with only a level different from the common roll, because of its wide flange with no inclination (or slope is very small), and thus should be added a set of vertical rolls simultaneously rolls, thus its rolling mill technology and equipment than the general complexity. China can produce the maximum rolling H beam height of 800mm, more than the combined section can be welded. H steel flange suitable for narrow beam or bending member, and wide flange h and h-beam steel pile is applicable to axial compression members or bending member. Ordinary beam, light beam as compared with HW, HN steel, etc. under the weight of the premise, w, ix, iy are not as common H-shaped steel beam and light beam of the wing to the edge of the root cause of the gradual thinning , there is a certain point of view, the ordinary beam and light beam model with its waist-high cm number of Arabic numerals, different web and flange thickness and flange width specifications to waist high (h) × leg width (b) × waist thick (d) of the coin number, such as "general workers 160 × 88 × 6", it means that the high waist of 160 mm, leg width of 88 mm, for the ordinary beam waist thick 6 mm. / "Light 160 × 81 × 5", it means that the high waist of 160 mm, leg width of 81 mm, thick waist light beam 5 millimeters. Ordinary beam model specifications can also be used, said that waist-high models of a few centimeters, such as general working 16 #. The same beam waist high, if several different legs wide and thick waist, plus abc model the right to be different, such as general workers 32 # a, 32 # b, 32 # c and so on. Hot-rolled ordinary beam specifications for the 10-63 #. Hot-rolled ordinary beam specifications supplied by the agreement between the 12-55 #.

Steel table can be found from its maximum available shear strength T Tmax = Q / Ib [BH ^ 2 / 8- / 8] where: Tmax is the maximum shear strength. T on behalf of the available shear strength into it, the beam can be calculated to withstand the maximum load. Q is a uniform load I beam cross-sectional moment of inertia to be Richard (cm ^ 4) in the steel sheet. The maximum width B of the I-beam cross-section. b h is the minimum width of the beam cross-section to the minimum width of the I-beam cross-section height. Calculate the height of the normal stress of H is the maximum width of beam cross section: Ysigma = M / WM = biggest moment = load multiplied by the distance W = flexural modulus. Set Ysigma = maximum allowable stress, the maximum load can be drawn.

Compared with last year, issuers of credit asset securitization is more diversified, foreign banks, city commercial, agricultural firms have begun to actively participate in this market. Q235B beam Last August, China's first single rural small and medium financial institutions issuing asset securitization project in the interbank market, which means that asset securitization project Issuer official expansion to rural small and medium financial institutions. Accordance with the regulatory agencies to support banks to issue credit asset securitization products of the mind, the stock of credit asset securitization through a table after the new line of credit to continue to invest in the "three rural" and small and micro enterprise sector. Q235B beam Industry analysts believe that this year, small and medium financial institutions issuing wishes more intense, mainly due to large companies over the past few years for the proportion of long-term credit granted in the period of economic downturn, some industry overcapacity liquidity problems, banks face to loan ratio assessment and other regulatory pressures, maneuvers some credit resources needed to carry out structural adjustment credit direction, asset securitization undoubtedly become an important channel. Q235B beam, however, these small financial institutions in circulation does not have a large size and strength, "local bank securitized products issuance is small, every single 10-3000000000 yuan." A rating agency structured Finance on the "Economic Information Daily" reporters, said, "Basically banks or asset securitization of corporate loans to do, especially at the local bank, credit type is relatively simple, almost no packaged for retail credit assets, and large banks credit assets Q235B beam or joint-stock banks is relatively richer. "In general, city commercial and agricultural firms a higher concentration of loans and each region has a very prominent characteristics of the industry," such as Shanxi local banks needle work Q235B The amount of the loan word steel coal enterprises issued on more, so this type of loan assets bag industry will be more, but from a ratings point of view we do not recommend the type is too concentrated, the regulatory requirements, it also requires some premium assets into the pool, so that small and medium financial institutions to do the amount of securitization of credit assets will not be much. "The source further said the rating agency.
