Automatic prefabricated part splitting method based on BIM and computing device

Abstract

The invention provides an automatic prefabricated part splitting method based on BIM and a computing device. The method comprises the steps that an overall BIM of a building project is designed, splitting parameters are built, and splitting rules for the number, the classification, the output information content and the project amount of a prefabricated part are made according to the preset splitting parameters; the overall BIM is classified according to the splitting parameters, and a building type is determined, so that mistakes are prevented from being made in the subsequent splitting process; the overall BIM is split into refined models step by step through two-time splitting, and in the subsequent part verification process, only part of models need to be verified, and the overall model does not need to be verified, so that the work efficiency is improved; the overall BIM is decomposed into a set of various parts and split into the minimum units meeting the production manufacturingand transporting requirements, and the part shapes are subjected to restoration verification, so that splitting errors are avoided; a production drawing of the part shapes is directly output, and theaim of one-key splitting design of the prefabricated part is achieved with the combination of the splitting requirements of the prefabricated part. Therefore, the accuracy and the efficiency for designing the drawing of the prefabricated part based on the BIM are improved.

Description

technical field [0001] The invention relates to the field of architectural design, in particular to a method and computing equipment for automatic splitting of prefabricated components based solely on BIM. Background technique [0002] In modern architectural design, with the development of BIM technology and the continuous maturity of BIM software, prefabricated architectural design based on BIM technology has become the mainstream. Building Information Modeling (Building Information Modeling) or Building Information Management (Building Information Management) is based on the relevant information data of construction projects, establishes a three-dimensional building model, and simulates the real information of buildings through digital information simulation. . It has eight characteristics of information completeness, information relevance, information consistency, visualization, coordination, simulation, optimization and graphing. The construction unit, design unit, co...

Problems solved by technology

[0003] In the existing technology, the design institute uses Revit software to design the building structure, and the drawing stage of the component drawings is manually split and drawn. The problems caused by the manual drawing of the drawings are low efficiency, error-prone, and the quality of the drawings is affected by the human factors of the designers. Greater impact
