Problems solved by technology

H-shaped steel profiles are hot-rolled and welded. Hot-rolled and welded have their own advantages, but most of the H-shaped steels used in engineering are welded and formed. The middle part of this welded and formed H-shaped steel has A web, the web has been using a flat structure for a long time. Although the H-shaped steel of this flat web has good strength, it has many consumables and high cost, which increases the economic burden on the user and increases the project cost.

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] 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.

[0033] 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.

[0034] The corrugated section of the corrugated web 1 can be arc-shaped, involute or trapezoidal; wh...

Abstract

The invention discloses a transverse waveform web H-shaped rolled steel, composed by welding web and two flank plates, where the web is between the two flank plates and its characteristic: the web is a waveform web with transverse ripples. The invention also discloses its making technique and a molding device of making the above web by primarily connecting, cold-bending and rolling, where the key part of the molding device is a pair of tooth form roller molding device. The H-shaped rolled steel has the characters of lightness, large bearing capacity, simple making technique and device, etc.

Description

technical field [0001] The present invention relates to steel structure engineering profiles, specifically corrugated web H-shaped steel and its manufacturing process. Background technique [0002] H-shaped steel structural profiles are widely used in buildings, bridges, exhibition halls, crane rolling tracks, etc. H-shaped steel profiles are hot-rolled and welded. Hot-rolled and welded have their own advantages, but most of the H-shaped steels used in engineering are welded and formed. The middle part of this welded and formed H-shaped steel has A web, the web has been using a flat structure for a long time. Although the H-shaped steel of this flat web has good strength, it has many consumables and high cost, which increases the economic burden on the user and increases the project cost. . Contents of the invention [0003] The purpose of the present invention is to provide a new H-shaped transverse corrugated web steel with less consumables, light weight and low cost u...
