Abstract

The invention discloses a manufacture method for double-curve H-shaped steel. The manufacture method comprises the following steps of: 1) reviewing the material quality of a supplied horizontal plate, flattening the horizontal plate, and pre-processing; 2) three-dimensional lofting by a computer, and spreading in a plane; 3) cutting and blanking on a numeric control cutting machine; 4) opening a groove on an H-shaped steel web, and carrying out the butt welding; 5) marking a bending line and an assembly line on the web and a flange plate; 6) manufacturing a bending jig frame according to three-dimensional coordinates; 7) bending the web and the flange plate via the method of flame rectification assisting cold bending formation; 8) manufacturing a assembly jig frame; 9) combining position welding and spot-welding on an upper flange plate and a lower flange plate respectively assembled on an assembly jig frame group; 10) welding the soldering seam between the web and the lower flange plate; 11) lifting the component from the jig frame, and turning over the component to weld the soldering seam between the web and the upper flange plate; and 12) returning the jig for a repeated inspection, and carrying out the three-dimensional coordinates detection through a total-station instrument. According to the manufacture method, used equipment is simple, and efficiencies on manufacture and production are improved.

Description

technical field

[0001] The invention relates to a method for manufacturing a hyperboloid H-shaped steel. Background technique

[0002] Today, with the rapid development of bridge steel structure technology, space hyperbolic structure H-shaped steel is also increasingly widely used in the field of bridge steel structure. At present, there is no mature experience in the production of hyperboloid H-shaped steel at home and abroad. Some professional manufacturers use special molds or large-scale cold bending equipment to make it. The cost is high and the cycle is long, which cannot meet the requirements of this project. Contents of the invention

[0003] The purpose of the present invention is to provide a method for manufacturing hyperboloid H-shaped steel. The present invention solves the difficult problem of making hyperboloid H-shaped steel. The equipment is simple, effective and cost-effective while ensuring manufacturing accuracy and simplifying the manufacturing process...
