Quantitative extraction method for transmission building component based on BIM (Building Information Modeling)

Abstract

The invention belongs to the technical field of quantitative extraction of buildings and discloses a quantitative extraction method for a transmission building component based on BIM (Building Information Modeling). The method comprises the steps of designing a BIM model through BIM design software by use of a design module, and sending model data to a conversion module and an integration module;deriving the BIM design model in the design module, by the conversion module, into an IFC (Industry Foundation Classes) file, and sending the IFC file to an extraction module; performing integration processing on the BIM model in the design module, and sending the processed data to the extraction module; and extracting the BIM model by use of the extraction module through receiving of the IFC fileof the conversion module and the integrated data of the integration module to form a geometrical model of the usage amount of a building structural component. According to the quantitative extractionmethod for the transmission building component based on the BIM, a complete information model can be possessed in the engineering design, a drawing file and the model can be automatically updated andassociated, the information conversion between related software is realized, the structural design is facilitated to be reliable, and the method lays the foundation for engineering construction in later period.

Description

technical field [0001] The invention belongs to the technical field of quantitative extraction of buildings, in particular to a method for quantitative extraction of transmission building components based on BIM. Background technique [0002] At present, there are many problems in the two-dimensional drawing method adopted in the traditional building structure construction drawing design, the design process is complicated, and a large amount of information cannot be taken into account. Automatic generation function, but there is no relevance and completeness of information, and it is not possible to ensure the consistency of information. [0003] BIM technology is to express the internal and external structures of engineering buildings in the form of three-dimensional models, and attach design information, construction information, and operation and maintenance information related to engineering buildings to the models for management, which can realize the management of engi...
