H型鋼與工字鋼的區(qū)別和用途說(shuō)明

發(fā)布時(shí)間:2023-02-25 來(lái)源:http://plisse.cn/

很多人認(rèn)為工字鋼是國(guó)內(nèi)的叫法,H型鋼是國(guó)外的叫法,其實(shí)這個(gè)認(rèn)知是錯(cuò)誤的。H型鋼和工字鋼從形狀上來(lái)說(shuō)是不一樣的,下面濟(jì)南型鋼廠家來(lái)講講H型鋼與工字鋼的區(qū)別和用途說(shuō)明。
Many people think that I-beam is a domestic term and H-beam is a foreign term. In fact, this cognition is wrong. H-beam and I-beam are different from each other in terms of shape. Next, Jinan section steel manufacturer will talk about the differences and uses of H-beam and I-beam.
1、工字型鋼不論是普通型還是輕型的,由于截面尺寸均相對(duì)較高、較窄,故對(duì)截面兩個(gè)主軸的慣性矩相差較大,因此,一般僅能直接用于在其腹板平面內(nèi)受彎的構(gòu)件或?qū)⑵浣M成格構(gòu)式受力構(gòu)件。對(duì)軸心受壓構(gòu)件或在垂直于腹板平面還有彎曲的構(gòu)件均不宜采用,這就使其在應(yīng)用范圍上有著很大的局限。
1. The moment of inertia of the two principal axes of the section is relatively different due to the relatively high and narrow section size of the I-shaped steel, whether it is ordinary or light, so it can only be directly used for members bent in the plane of its web or to form a lattice load-bearing member. It is not suitable for axial compression members or members with bending perpendicular to the plane of the web, which limits its application.
2、H型鋼屬于高效經(jīng)濟(jì)截面型材(其它還有冷彎薄壁型鋼、壓型鋼板等),由于截面形狀合理,它們能使鋼材更高地發(fā)揮效能,提高承裁能力。不同于普通工字型的是H型鋼的翼緣進(jìn)行了加寬,且內(nèi)、外表面通常是平行的,這樣可便于用高強(qiáng)度螺栓和其他構(gòu)件連接。其尺寸構(gòu)成合理系列,型號(hào)齊全,便于設(shè)計(jì)選用(除了吊車梁用工字型鋼) 。
2. H-shaped steel is an efficient and economical section profile (other cold-formed thin-walled steel, profiled steel, etc.). Because of the reasonable section shape, they can make the steel more efficient and improve the cutting capacity. What is different from the common I-shaped steel is that the flange of H-shaped steel is widened, and the inner and outer surfaces are usually parallel, which makes it easy to connect with other components with high-strength bolts. Its size composition is reasonable and its model is complete, which is convenient for design and selection (except for I-shaped steel for crane beam).
3、H型鋼的翼緣都是等厚度的,有軋制截面,也有由3塊板焊接組成的組合截面。工字鋼都是軋制截面,由于生產(chǎn)工藝差,翼緣內(nèi)邊有1:10坡度。H型鋼的軋制不同于普通工字鋼僅用一套水平軋輥,由于其翼緣較寬且無(wú)斜度(或斜度很小),故須增設(shè)一組立式軋輥同時(shí)進(jìn)行輥軋,因此,其軋制工藝和設(shè)備都比普通軋機(jī)復(fù)雜。國(guó)內(nèi)可生產(chǎn)的大軋制H型鋼高度為800mm,超過(guò)了只能是焊接組合截面。
3. The flange of H-beam is of equal thickness, with rolling section and combined section composed of three plates welded. All I-beams are rolled sections. Due to poor production technology, the inner edge of the flange has a 1:10 slope. The rolling of H-beam is different from that of ordinary I-beam with only one set of horizontal rollers. Because of its wide flange and no slope (or small slope), it is necessary to add a set of vertical rollers to roll at the same time. Therefore, its rolling process and equipment are more complex than ordinary rolling mill. The height of the large rolled H-shaped steel that can be produced in China is 800mm, which is more than the welded composite section.

4.工字鋼的邊長(zhǎng)小,高度大,只能承受單方向的力。
4. The side length of I-beam is small and the height is large, and it can only bear the force in one direction.
5.H型鋼槽深,厚度大,可以承受兩個(gè)方向的力。
5. The H-shaped steel groove is deep and thick, and can bear the force in two directions.
6.隨著鋼結(jié)構(gòu)建筑的發(fā)展需要,只有工字鋼是不行的,還要加厚工字鋼,用于承重柱容易失穩(wěn)。
6. With the development of steel structure buildings, only I-beam is not feasible, and I-beam should be thickened, which is easy to lose stability when used for load-bearing columns.
7.工字鋼只能用于橫梁,而H型鋼才能用于結(jié)構(gòu)的承重柱。
7. I-beams can only be used for beams, while H-beams can only be used for load-bearing columns of structures.
8.H型鋼是一種斷面力學(xué)性能較工字鋼優(yōu)良的經(jīng)濟(jì)型斷面鋼材,因其斷面的形狀與英文字母“H”相同而得名。熱軋H型鋼的翼緣比工字鋼寬、側(cè)向剛度大、抗彎能力強(qiáng)。同等規(guī)格下H型鋼理重較工字鋼輕。
8. H-shaped steel is an economic section steel with better mechanical properties than I-shaped steel. It is named because its section shape is the same as the English letter "H". The flange of hot-rolled H-beam is wider than that of I-beam, with large lateral stiffness and strong bending resistance. The weight of H-shaped steel is lighter than I-shaped steel under the same specification.
9.工字鋼翼緣是變斷面靠腹板部厚,外部??;H型鋼的翼緣是等斷面。
9. The flange of I-beam is thick at the web of variable section and thin at the outside; The flange of H-shaped steel is of equal section.
