Three-dimensional model data processing method for steel structure assembling members based on BIM technology

Abstract

The invention discloses a three-dimensional model data processing method for steel structure assembling members based on a BIM technology. The method comprises the steps that A, a virtual three-dimensional model of all pre-assembled members of a steel structure is constructed according to a design drawing of all the pre-assembled members of the steel structure and design parameter members; B, the virtual three-dimensional model and corresponding steel member entity structure information are subjected to comparison and review; and C, three-dimensional space operation is performed on the reviewed virtual three-dimensional model of all the pre-assembled members of the steel structure through the BIM technology to realize pre-assembling. According to the method, the virtual three-dimensional model of all the pre-assembled components of the steel structure is constructed to perform simulated steel structure assembling operation, pre-assembling investment cost can be reduced beneficially, the manufacturing cycle can be shortened, simulated assembling precision is high, and actual assembling quality in a later period is ensured beneficially.

Description

technical field [0001] The invention relates to the digital technical field of the steel structure industry, in particular to a method for processing three-dimensional model data of steel structure assembly components based on BIM technology. Background technique [0002] Since the late 1980s, steel structures have been widely used in the field of construction. With the development of the economy and the improvement of steel industry technology and production capacity, high-rise buildings, stadiums, airport terminals and other buildings have gradually increased, and steel structures have entered a period of rapid development. However, in most steel structure processing enterprises in China, traditional methods such as steel rulers, guy wires, lofting wires, and inspection templates are commonly used to check whether steel components meet the design requirements. For complex steel components, physical pre-assembly is also required to check the spatial position of the compone...
