Manufacturing optimization method for multi-curvature special-shaped curved surface steel structure

Abstract

The invention discloses a manufacturing optimization method for a multi-curvature special-shaped curved surface steel structure. The method comprises the steps: adopting a BIM to create a steel memberthree-dimensional visualization model; outputting and auditing steel member manufacturing parameters based on the BIM model; making lofting blanking based on the parameters which are approved by auditing; adopting a BIM to create a dynamic simulation process of procedures of plate splicing, profile bending, cutting, assembling, welding, hole forming, assembling, riveting part blanking, welding inspection, rust prevention and acceptance inspection; and manufacturing steel structure strictly according to the simulation process. According to the method, the steel member three-dimensional visualization model is created based on the BIM technology, the steel member manufacturing parameters are output, the three-dimensional visualization dynamic simulation process of each procedure is created,steel structure manufacturing is carried out strictly according to the simulation process, the multi-curvature special-shaped steel structure construction manufacturing process is effectively improved, and good social benefits and economic benefits are obtained.

Description

technical field [0001] The invention belongs to a method for manufacturing a multi-curvature special-shaped curved surface steel structure, in particular to an optimization method for manufacturing a multi-curvature special-shaped curved surface steel structure. Background technique [0002] At present, the manufacturing process of complex steel structures with multi-curvature and special-shaped surfaces is complicated, easy to be confused, and requires high precision. Errors often occur in the ordinary manufacturing process, resulting in waste of materials, and the accumulation of errors leads to deformation of the final product, which cannot fully meet the design requirements. For steel members with multi-curvature and special-shaped surfaces, it is even more difficult to make them fully meet the design requirements. [0003] With the continuous development of technologies such as BIM, its functions are also becoming more and more perfect. Through the creation of three-di...
