翼缘加强型工字钢
摘要：
本发明提供了一种翼缘加强型工字钢，包括第一翼板、第二翼板和腹板，所述第一翼板与所述第二翼板平行且长和宽都相等，所述腹板其中一端垂直连接于所述第一翼板中部，另一端垂直连接于所述第二翼板中部；所述第一翼板和所述第二翼板两者中的至少一个的翼缘向内卷曲，形成加强结构。本发明所提供的翼缘加强型工字钢在所述第一翼板和所述第二翼板两者中的至少一个的翼缘向内卷曲，形成加强结构，使得工字钢的翼板得到拉伸，达到拉应力增强作用，从而使得工字钢的承重性能得到提高。
摘要（英）：

The invention provides flange-reinforced H-shaped steel. The flange-reinforced H-shaped steel comprises a first wing plate, a second wing plate and a web plate. The first wing plate and the second wing plate are parallel and are the same in length and width. One end of the web plate is perpendicularly connected to the middle of the first wing plate, and the other end of the web plate is perpendicularly connected to the middle of the second wing plate. The flange of at least one of the first wing plate and the second wing plate is curved inwards to form a reinforcing structure. According to the flange-reinforced H-shaped steel, the flange of at least one of the first wing plate and the second wing plate is curved inwards to form the reinforcing structure, so that the wing plates of the H-shaped steel are stretched, the pulling stress is improved, and the bearing performance of the H-shaped steel is improved.
