Manufacturing method of space curve profile steel component

Abstract

The invention relates to a manufacturing method of a space curve profile steel component. The manufacturing method comprises the following steps: (1) part manufacturing: three-dimensional analysis software is adopted to loft a curve structure to obtain an unfolding shape of a space curve plate; a process quantity is added; and a part is produced through high-precision numerical control flame cutting equipment; (2) curved surface forming requirement: the minimum curvature in the plate length direction is calculated by analyzing the space curve plate; roller plate equipment is used for prebending; and a characteristic point reaches a designed linetype requirement by a numerical control ejection mode; (3) plate unit production requirement: a special jig model is clamped; reinforcing ribs are assembled in sequence; the assembly gaps and angles of the reinforcing ribs are controlled; and a process with low line energy can be adopted to weld during welding; and (4) steel component production requirement: a special jig model is produced according to the characteristic point; the tightness between a baseplate of the steel component and the jig model is guaranteed; separation plates and other plates are assembled in sequence; and the tightness of all the plates is guaranteed to realize whole linetype of the structure.

Description

technical field [0001] The invention relates to a kind of box-shaped steel components such as space curved steel box girders and steel rods, which adopts the method of classification and combined application of multiple manufacturing technologies to control the space line shape of the manufactured steel components so as to make them meet the design structure requirements A method for manufacturing a space curve steel component. Background technique [0002] In recent years, the construction of urban steel structures and steel bridges has developed rapidly, especially the market for urban ramp steel bridges is increasing day by day. The structural design of urban ramp bridges mostly adopts box-type and rod structures, and the structural form is densely reinforced in a small space. It belongs to the combined line structure of plane curve, vertical curve and twisted line. [0003] At present, the manufacturing technology of steel members of plane line and vertical line is rel...

Problems solved by technology

In the past, the straight line was used instead of the curved line to adjust the overall line type through the joints, but the final bridge line type was often uneven. Although it did not affect the structural force, the appearance of the bridge was difficult to achieve the aesthetic requirements
