Country Garden Prefabricated House Design Drawings

Currently, no directly publicly available design drawings for Country Garden's prefabricated houses have been found, but the design logic can be inferred from the technical characteristics of its prefabricated components. Country Garden primarily relies on the SSGF new construction technology and prefabricated concrete structural systems in the field of prefabricated construction. The core lies in achieving efficient construction through standardized prefabricated components, with design drawings needing to revolve around the specifications, connection methods, and architectural functions of the components. The following analysis is conducted from three aspects: technical principles, component types, and design key points:

I. The Technical Basis of Prefabricated Components Determines the Design Direction

Country Garden's prefabricated wall panels are made from raw materials such as cement, ceramsite, and sand, with cold-drawn low-carbon steel bars embedded inside. They are manufactured through core-pulling and high-temperature steam curing processes. This process endows the wall panels with properties such as high strength (compressive strength can reach over 15MPa), fire resistance (fire resistance limit exceeds 2 hours), and sound insulation (airborne sound insulation rating ≥ 45dB), while supporting designs in various specifications (e.g., thickness ranging from 120-300mm) and panel types (e.g., straight and L-shaped). Design drawings must clearly indicate the material parameters, dimensional modules, and performance grades of the components. For example, exterior wall panels need to be labeled with insulation layer thickness and fire rating, while interior wall panels require sound insulation requirements to ensure that the components meet the architectural functional needs.

II. The Prefabricated Structural System Influences the Composition of Design Drawings

Its prefabricated concrete structures include types such as prefabricated pile caps, prefabricated ground beam molds, PC insulated roof panels, and composite floor slabs. The type of component directly determines the modular division in the design drawings. For example:

• Horizontal components (such as composite floor slabs) need to be labeled with span, load, and connection methods to beams;
• Vertical components (such as prefabricated wall panels) require clarification of anchoring nodes with floor slabs and the pre-embedded positions of water and electricity pipelines;
• Irregular components (such as bay windows) need detailed three-dimensional dimensions and splicing details with the main structure. Design drawings typically include component layout plans, detailed node drawings, and embedded part positioning diagrams. For some complex projects, BIM models may also be provided to assist in construction.

III. Design Needs to Balance Standardization and Flexibility

Country Garden's prefabrication technology emphasizes the principle of "fewer specifications, more combinations", adapting to different building types (residential, office, hotel, etc.) through standardized components. In design drawings, component dimensions need to conform to modular coordination standards (e.g., 300mm as the basic module) while leaving room for adjustments. For example, in residential projects,户型 variations can be achieved by combining wall panels of different specifications, and design drawings need to indicate the component replacement rules for variable areas; for public buildings, large space requirements can be met through the modular arrangement of prefabricated beams and columns, with design drawings needing to highlight the structural load-bearing system.

To obtain specific design drawings, the following approaches are recommended: Contact Country Garden's official technical department to apply for case materials; refer to the illustrations in its published "SSGF New Construction Technology White Paper"; and consult the prefabricated building project drawings filed with local housing and construction departments. The core value of design drawings lies in guiding component production and on-site construction, and in actual projects, customization is required based on parameters such as geological conditions and seismic requirements.
