Prefabricated Component House Model Design
The design of prefabricated component house models requires comprehensive consideration of various factors, including design methods, component classification, drawing content, and case references.
In terms of design methods, design institutes are currently transitioning from traditional CAD drawing to BIM design and drawing output. They adopt a forward design approach that involves 3D BIM modeling followed by 2D drawing output to meet the development needs of engineering construction. This method provides a more intuitive display of house models and improves design efficiency and accuracy.
Regarding component classification, the same prefabricated component is divided into simplified and detailed components. Simplified components are used for conventional plan and elevation drawings in project models, while detailed components are used for detailed design drawings and modeling, placed in independent project models for detailed drawing design. Although both have the same 3D dimensions, detailed components include more fine parts, such as bolt sleeves, air conditioning reserved holes, and galvanized steel plates, to meet more precise design requirements.
In terms of drawing content, by utilizing detailed and simplified components, detailed drawings of prefabricated exterior wall components can be produced, including elevation details, section details, etc. Embedded part location drawings include statistical tables for metal embedded parts used for diagonal bracing, installation details for metal embedded parts used for diagonal bracing, and statistical tables for prefabricated exterior walls. Additionally, vertical numbering drawings for prefabricated components generated from simplified components are also produced. These drawings provide detailed guidance for the production and installation of prefabricated components.
In terms of case references, the R&D building of iSoftStone achieved excellent facade effects and performance by optimizing its exterior wall plan and adopting a prefabricated concrete exterior wall cladding system. The prefabricated modular mobile house demonstrates the advantages of factory-integrated prefabrication, featuring a technological appearance and rapid installation. Another prefabricated modular house building achieves rapid assembly installation through limiting and auxiliary structures, improving installation efficiency and reducing costs. These cases provide valuable experience and inspiration for the design of prefabricated component house models.
