Structural Drawings of a Six-Story Prefabricated House

The currently available structural drawings for six-story prefabricated houses mainly include the structural construction drawings of a six-story brick-concrete prefabricated panel residential building in Sichuan, while the drawings of Building 7# in Anhui Zichen Residence can serve as supplementary references, but attention should be paid to the differences in their structural forms.

1. Drawings of a Six-Story Brick-Concrete Prefabricated Panel Residential Building in Sichuan
These drawings represent a typical case of a six-story prefabricated house structure, adopting a brick-concrete structural system with prefabricated panels for the floor slabs and cast-in-place panels for the roof. The drawings include the following core content:

• Foundation Section: Provides a foundation plan layout, clarifying the layout of independent or strip foundations, and marking foundation dimensions, reinforcement, and concrete strength grades to ensure structural stability.
• Structural Plan Layout: Covers structural plans from the first to the sixth floors, displaying the laying direction, splicing method, and reserved opening positions of the prefabricated floor slabs, while also marking the dimensions and reinforcement of load-bearing members such as beams and columns.
• Roof Design: The roof panels are constructed using cast-in-place technology. The drawings detail the roof slope, drainage direction, and waterproof layer construction to prevent leakage risks.
• Drawing Characteristics: The files are in editable CAD format, supporting adjustments to dimensions or reinforcement according to actual needs, suitable for direct design or renovation references for brick-concrete prefabricated houses.

2. Reference Value of the Drawings of Building 7# in Anhui Zichen Residence
These drawings feature a special-shaped column frame-shear wall structure, which, although not a pure prefabricated structure, can serve as a supplementary reference for the structural design of six-story residential buildings:

• Structural System Differences: The frame-shear wall structure primarily consists of a reinforced concrete frame with a low proportion of prefabricated components. However, the design logic in the drawings, such as wall and column layouts and load transfer paths, can be referenced.
• Drawing Content: Includes 23 drawings such as design descriptions, foundation plans, and structural drawings of wall columns on each floor, with detailed annotations on structural materials, seismic grades, and construction points, suitable for understanding the overall framework of high-rise residential building structural design.

3. Other Considerations

• Drawing Acquisition Method: The above drawings should be obtained through formal design platforms or by contacting the original design units to avoid structural safety hazards caused by using drawings from non-official channels.
• Design Adaptability: The design of prefabricated houses should consider local climate, geological conditions, and construction capabilities. For example, parameters such as seismic fortification intensity and wind loads should comply with regulatory requirements.
• Professional Review: When directly using existing drawings, it is recommended to have them reviewed and adjusted by a structural engineer to ensure that the connection nodes and load calculations of prefabricated components comply with current standards.
