BIM-based fabricated member parametrization design method

Abstract

The invention provides a BIM-based fabricated member parametrization design method. The method comprises the steps of 1: according to functions of fabricated building members, performing component disassembly on a building structure drawing to form a plurality of disassembly design schemes, wherein the schemes are specifically expressed in a form of "total construction design + BIM issued component disassembly drawing"; 2: by using Revit software, establishing three-dimensional models of the building members in the disassembly design schemes; 3: by applying three-dimensional modeling software,making rough profiles of the members, adding parameters, and forming controllable models; 4: through a geometric relationship between the parameters of the members, creating a relational expression;and 5: from the three-dimensional models of the members, obtaining a two-dimensional graph comprising the parameters of the members and the relationship expression. According to the design, the drawing needed by factory production is quickly and accurately generated, and the material requirement amount can be automatically calculated and summarized according to the parameters in the drawing.

Description

technical field [0001] The invention belongs to the technical field of intelligent buildings, and in particular relates to a BIM-based parametric design method for assembled components. Background technique [0002] The characteristics of parameterization, integration, standardization, and support for the whole life cycle of the BIM technology platform provide important support for the integration of architectural design and construction, making the construction of complex multi-dimensional digital models no longer a problem. Architectural designers use the BIM software platform to construct specific parametric models. The construction of this method is not only a combination of geometric space and geometric shapes, but also covers many parameter data, which is of great importance to ensure the quality of architectural design and improve the overall work efficiency and level. Significance. [0003] The deepening design of prefabricated components is an important part of arc...

Problems solved by technology

At present, this part of the drawings is obtained from the split design drawings after deepening the design. It mainly uses two-dimensional drawing software such as CAD to split and design the drawings required for the production of the prefabricated factory according to the design specifications. Due to the large workload, the size of the components Subtle changes increase the chance of error

Moreover, there will be large differences in the size of the components in the later stage. When they are transported to the construction site for splicing, they cannot be assembled according to the scheduled plan, resulting in secondary construction or multiple constructions. In addition to transportation costs, a lot of resources are wasted.
