Research on detailed design methods of precast components in prefabricated buildings based on BIM technology
Abstract
There are still problems such as low standardization and low interoperability in the prefabricated building precast component design with BIM technology, which lead to the absence and separation of precast components in the deepening design stage and other stages. Therefore, how to solve the problem of mutual loss and separation among the various levels of the precast component deepening design process has become one of the key problems to be urgently resolved. To link up each stage of the deepening design and improve its efficiency. Based on semi-structured interview, the primary and secondary functional modules required for the detailed design of precast components were clarified. Based on C# programming language and Revit API, the Revit API-based the design platform for deepening precast components (DPDPC) of prefabricated buildings was independently developed by using secondary development technology. Based on the research method of case analysis, this paper uses the DPDPC to study and demonstrate the actual project, and finally verifies the feasibility of the precast component deepening design process. The research results show that, the prototype of the DPDPC constructed includes three first-level function modules and eleven second-level function modules. The detailed design process of precast components with Revit as the core is component split → component design → optimized design → component drawing → material list. This paper provides clarity on the main process of precast deepening design. The prototype of DPDPC constructed not only helps to better connect each level of prefabricated building precast component deepening design, but also helps to display the functional requirements of each level of deepening design process through a systematic platform from the technical level. To provide a reference for further design of precast components.
