Abstract

The invention relates to the technical field of building construction, and discloses a method for arranging high-precision steel bars of linear bearing platform type components based on a BIM technology. The method mainly comprises: extracting surface parameters of the linear bearing platform type component, dividing all steel bars into different types according to different space positions, and obtaining an initial dot matrix or model line on an initial offset surface according to diameter parameters, arrangement interval parameters and protective layer thickness of all types of steel bars; performing model line array offset or dot matrix offset along the longitudinal direction to obtain a steel bar model line array, and finally generating a steel bar model. According to the method, accurate positioning and self-adaptive arrangement of the steel bars in the linear bearing platform type component are achieved through computer programming, internal collision of the steel bars is avoided, and steel bar entities are rapidly generated in batches. The problems that in existing deepening design, linear bearing platform type components are low in arrangement accuracy and disordered in rule are solved. And meanwhile, the method can be used for technical disclosure of field construction and has the advantages of improving machining precision and construction efficiency and the like.

Description

technical field [0001] The present invention relates to a technical field of building construction, in particular to a BIM-based technology that parametrically sets the size and spatial position of various types of steel bars in the linear cap components of the BIM three-dimensional model, so that the high-precision layout of the steel bar solid model Methods. Background technique [0002] Building Information Modeling (Building Information Modeling) is based on the relevant information data of the construction project as the basis of the model to establish the building model, and simulate the real information of the building through digital information simulation. It has five characteristics of visualization, coordination, simulation, optimization and plotting. [0003] BIM modeling technology is the basis of BIM technology application, and it is precisely because of the modeling process that a series of BIM functions can be completed. Therefore, the efficiency and accura...
