I-shaped beam
The invention discloses an I-shaped beam which comprises a first flange flat plate, a first flange rib plate, a second flange flat plate and a connecting plate; the first flange flat plate and the first flange rib plate are integrally formed and are of a T-shaped structure; and the two ends of the connecting plate are connected with the first flange rib plate and the second flange flat plate respectively. According to the I-shaped beam produced through hot rolling and butt welding, a T-shaped welding joint form of flanges and web in an existing I-shaped beam is changed into a butt welding joint form of the first flange rib plate and the second flange rib plate with webs, so that welding defects are reduced, the cross position of welding seams in two directions is changed, the welding residual stress of the I-shaped beam is reduced, the fatigue property, the economical efficiency and the durability of the I-shaped beam are greatly improved, and the difficult problems which are difficult to break through in the industry all the time are solved.
本发明公开了一种工形梁，包括第一翼缘平板、第一翼缘肋板、第二翼缘平板和连接板，第一翼缘平板和第一翼缘肋板一体成型且呈T形结构，连接板的两端分别与第一翼缘肋板和第二翼缘平板连接。本发明通过热轧‑对接焊生产形成的工形梁，将现有工形梁中翼缘与腹板的T型焊接接头形式改变为第一翼缘肋板和第二翼缘肋板分别与腹板的对接焊接接头形式，减少了焊接缺陷的产生；改变了两向焊缝交叉的位置，降低了工形梁的焊接残余应力，大大提高工形梁的疲劳性、经济性和耐久性，解决了行业内一直难以突破的难题。
