A forming method of bending and torsion members based on bim technology

Abstract

The invention discloses a forming method of a bent / torsional component based on a BIM technology. The forming method comprises the following steps: (1) establishing a BIM model of a bent / torsional component, guiding the established BIM model into 3D3S, and establishing a world coordinate system so as to generate absolute coordinates of the bent / torsional component relative to of measurement control points; (2) determining the XOY plane of the component, converting the absolute coordinate system into a relative coordinate system using XOY as the plane; besides, selecting a plurality of control points on the component so as to generate relative coordinates to be used as coordinates for processing control points of the bent / torsional component; and (3) performing push bending and torsion processing on the component to be processed so as to enable each control point to reach the vector height corresponding to the relative coordinates. According to the forming method disclosed by the invention, a parameterized three-dimensional model is established by utilizing related software of BIM, the absolute coordinate value of the bent / torsional component at each mounting key point is read from the parameterized three-dimensional model, and the relative coordinate values for a factory to process key points are calculated by utilizing a coordinate conversion technology, so that a total station is assisted to complete precise control during the manufacturing and the mounting of the bent / torsional component

Description

technical field [0001] The invention relates to a construction quality control method of a steel structure hyperboloid bending and torsion member, in particular to a BIM technology-based forming method of a bending and torsion member, which belongs to the field of construction technology. Background technique [0002] At present, the in-depth design and processing of steel structure bending and torsion members are relatively complicated, and the overall cost is high. However, due to its special visual viewing effect, it is more and more used in large-scale steel structures with irregular curved surfaces. However, at present, domestic large-scale steel structure manufacturers do not have mature construction experience in the production of bending and torsion members, nor have they developed any complete equipment suitable for the production of bending and torsion members. There are no relevant regulations on control, so for the production and installation of bending and torsi...

Problems solved by technology

This method is mainly suitable for large components with rectangular cross-sections. The bending and torsion control of the steel plates on each component surface is mainly the linear shape of the four sides. The control requirements are relatively high, and it is difficult to accurately control the deformation of each plate, so there will be large errors in assembly.

[0006] The above method is only applicable to circular pipe sections and composite box sections, and the section of bending and torsion members involved in many projects is a rectangular section of section steel, obviously this method is not applicable
