Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0031] An H-shaped steel material with a transverse corrugated web, which is welded by a web 1 and two side panels 2 and 3, the web 1 is located in the two side panels 2 and 3, and is characterized in that the web 1 is Corrugated corrugated web. Such as figure 1 As shown, H, B, L in the figure are respectively the web height of the H-shaped steel of the present invention, the width and the length of the wing plate, and its size ranges are respectively: H=300~6000mm, B=100~800mm, L =3000~25000mm.
[0032] The transverse corrugated web 1 of the present invention can be formed by welding or one-time continuous cold bending and rolling, but the corrugated web with transverse corrugation formed by one-time continuous cold bending and rolling is the best.
[0033] The corrugated section of the corrugated web 1 can be arc-shaped, involute or trapezoidal; wh...
