Fabricated bridge parameterization implementation method based on BIM technology

Abstract

The invention discloses a fabricated bridge parameterization implementation method based on a BIM technology. The method is characterized in that: the method comprises the steps of precast beam parameterization design, framework parameterization design and steel bar parameterization design. According to the prefabricated beam parameterization design, parameterization space beam arrangement is achieved by combining a space beam arrangement line obtained and generated through main line information with prefabricated beam main body parameterization, wherein the prefabricated beam main body parameterization comprises diaphragm plate parameterization, beam body parameterization and wet joint automatic sewing; and the framework parameterized design, the steel bar parameterized design and the precast beam parameterized design jointly form the fabricated bridge BIM parameterized design platform. According to the method, reasonable parameterized assembly type bridge design is adopted, the digital design efficiency of the assembly type bridge can be improved to the maximum extent, and the design cost is saved.

Description

technical field [0001] The present invention relates to the field of prefabricated bridge implementation, specifically a BIM technology-based parametric design method for prefabricated bridges and a system implementation method for parametric design, component correlation design, parameter-driven shape design, and collaborative design. Through this method It can quickly build and modify the BIM model. Background technique [0002] Bridge BIM models have the characteristics of relatively few types, large quantities, and relatively complex spatial locations. For example, the bridge BIM models are modeled one by one by manual direct modeling, because most components are repetitive, such as some bridges. The height of the straight section of the pier is different, so it is necessary to model each pier column one by one. The initial model is not helpful for the later use of similar models, which eventually leads to a long modeling time. This will cause great difficulties to the ...

[0002] Bridge BIM models have the characteristics of relatively few types, large quantities, and relatively complex spatial locations. For example, the bridge BIM models are modeled one by one by manual direct modeling, because most components are repetitive, such as some bridges. The height of the straight section of the pier is different, so it is necessary to model each pier column one by one. The initial model is not helpful for the later use of similar models, which eventually leads to a long modeling time. This will cause great difficulties to the development of BIM

[0003] In addition, the workload of the bridge BIM model is relatively large, and there are only differences in individual attributes and positional relationships among the various components. Using manual direct modeling will lead to a huge workload, such as the box girder, pile foundation, and pier body of the bridge. Wait

The time cost caused by the huge workload is also very huge, which will have a very negative impact on the development of BIM

[0004] The bridge model completed by manual direct modeling is an opposite individual and has no similarity. If you encounter a similar bridge BIM project, the previous model work will not be transferred to the next project for continued use

[0005] At present, the BIM design of traditional prefabricated bridges mainly adopts manual direct modeling. Although there are some means and methods of rapid modeling, it has not solved how to parametrically design
