广东佛山乐从H型钢批发,Q235H型钢价格,Q345BH型钢厂家直销

H型钢分为4类,其代号为:

等翼缘H型钢 HP (截面高度=宽度)

宽翼缘H型钢 HW(W为Wide英文字头)

中翼缘H型钢 HM(M为Middle英文字头)

窄翼缘H型钢 HN(N为Narrow英文字头)

 

工字钢 HW HM HN H型钢的区别

  工字钢翼缘是变截面靠腹板部厚,外部薄; H型钢的翼缘是等截面

  HW HM HN H是H型钢的通称,H型钢是焊制; HW HM HN是热轧

  HW 是H型钢高度和翼缘宽度基本相等;主要用于钢筋砼框架结构柱中钢芯柱,也称劲性钢柱;在钢结构中主要用于柱

  HM 是H型钢高度和翼缘宽度比例大致为1.33~~1.75 主要在钢结构中:用做钢框架柱在承受动力荷载的框架结构中用做框架梁;例如:设备平台

  HN 是H型钢高度和翼缘宽度比例大于等于2,主要用于梁;工字钢的用用途相当于HN型钢;

  1、工字型钢不论是普通型还是轻型的,由于截面尺寸均相对较高、较窄,故对截面两个主袖的惯性矩相差较大,因此,一般仅能直接用于在其腹板平面内受弯的构件或将其组成格构式受力构件。对轴心受压构件或在垂直于腹板平面还有弯曲的构件均不宜采用,这就使其在应用范围上有着很大的局限。

  2、 h型钢属于高效经济裁面型材(其它还有冷弯薄壁型钢、压型钢板等),由于截面形状合理,它们能使钢材更高地发挥效能,提高承裁能力。不同于普通工字型的是h型钢的翼缘进行了加宽,且内、外表面通常是平行的,这样可便于用高强度螺桂和其他构件连接。其尺寸构成合理系列,型号齐全,便于设计选用。

  3、h型钢的翼缘都是等厚度的,有轧制截面,也有由3块板焊接组成的组合截面。工字钢都是轧制截面,由于生产工艺差,翼缘内边有1:10坡度。H型钢的轧制不同于普通工字钢仅用一套水平轧辊,由于其翼缘较宽且无斜度(或斜度很小),故须增设一组立式轧辊同时进行辊轧,因此,其轧制工艺和设备都比普通轧机复杂。国内可生产的最大轧制h型钢高度为800mm,超过了只能是焊接组合截面。

  我国热轧H型钢国标(GB/T11263-1998)将h型钢分为窄翼缘、宽翼缘和钢桩三类,其代号分别为hz、hk和hu。窄翼缘h型钢适用于梁或压弯构件,而宽翼缘h型钢和h型钢桩则适用于轴心受压构件或压弯构件。工字钢与H型钢相比,等重量前提下,w、 ix、 iy都不如h型钢
