Construction engineering data modeling method based on BIM (Building Information Modeling) technology

Abstract

The invention relates to a construction engineering data modeling method based on the BIM (Building Information Modeling) technology. The technical scheme of the construction engineering data modeling method comprises the steps of: primary modeling: carrying out visual geometric modeling design on a project through Rhino software, and determining a building shape scheme; secondary modeling: finishing the informatization definition of a three-dimensional primitive in Revit software, wherein the informatization definition of the three-dimensional primitive includes building modeling, structure modeling and equipment modeling, and the building modeling, the structure modeling and the equipment modeling are simultaneously carried out and are mutually associated; model optimization: on the basis of a software analysis platform, carrying out analogue simulation on the model finished in the second step, and finally finishing the further optimization of the model; and integrating a building data model into a BIM information operation platform. The construction engineering data modeling method overcomes the problems that traditional AutoCAD (Computer Aided Design) software information transmission has the defects of losses or distortion, poor cooperativity, lack of equipment data information and the like and the defect that a simulation test can not be carried out. Data on a traditional drawing and text is imported into a three-dimensional model, resources are integrated through the integrated data model, an interactive cooperative capability is good, engineering quality is improved, construction cost is lowered, a construction period is shortened, and safety is improved.

Description

technical field [0001] The invention relates to the field of BIM technology, in particular to a construction engineering data modeling method based on BIM technology. Background technique [0002] With the increasing informatization of buildings, the amount of data to be faced in the project construction and operation management stages of construction projects has increased significantly, and the construction tasks have become increasingly arduous. [0003] Before the present invention was made, traditional construction engineering data integration usually used AutoCAD software, with two-dimensional drawing as the core. These two-dimensional professional drawings have a large amount of information, strong professionalism, and a high degree of abstraction, resulting in loss or distortion of data in different stages of the project and transmission between different disciplines. In the process of data integration (CAD design), the data interaction between various disciplines i...

Problems solved by technology

These two-dimensional professional drawings have a large amount of information, strong professionalism, and a high degree of abstraction, resulting in loss or distortion of data in different stages of the project and transmission between different disciplines

In the process of data integration (CAD design), the data interaction between various disciplines is relatively closed, and the coordination is poor

Designers spend a lot of time on drawing and coordination, resulting in insufficient investment in core work such as scheme design and professional technical design that are related to design quality, resulting in an increase in the workload of later revisions

On the other hand, traditional CAD blocks only express shape parameters and lack equipment data information, so simulation tests such as energy consumption analysis and working state simulation cannot be performed, making it impossible for construction personnel to conduct construction, operation and management of construction projects during the design stage. Make a reasonable program evaluation, which greatly increases the difficulty of carrying out the follow-up work of the project
