Images of Prefabricated Components for Whole Houses

Currently, images of prefabricated components for whole houses cannot be provided directly, but their common types and characteristics can be introduced in detail.

Prefabricated components for whole houses are a crucial part of modern industrialized building production. By being prefabricated in factories and assembled on-site, they can significantly enhance construction efficiency and building quality. Their core types include the following five major categories:

1. Prefabricated Floor Slabs

• Prefabricated Solid Slabs: Molded as a whole through casting, they have strong load-bearing capacity and are suitable for areas with high structural stiffness requirements, but they are relatively heavy.
• Prefabricated Hollow Slabs: With hollow cavities inside, they reduce self-weight while maintaining a certain load-bearing capacity and are commonly used for residential floor surfaces.
• Prefabricated Composite Slabs: Composed of a prefabricated base slab and an on-site cast layer, they combine the advantages of prefabrication and cast-in-place construction, improving construction efficiency.
• Prefabricated Balconies: Integrally formed in factories, including details such as railings and drainage channels, they can be directly installed on the main structure, shortening the construction period.

2. Prefabricated Beams

• Prefabricated Solid Beams: Suitable for large-span or heavy-load scenarios, such as the top beams of underground parking garages.
• Prefabricated Composite Beams: Prefabricated at the bottom and cast in place at the top, they balance construction speed and structural integrity.
• Prefabricated U-shaped Beams: With the opening facing downwards, they facilitate the embedding of pipelines and are commonly used in projects such as subway tunnels.

3. Prefabricated Walls

• Prefabricated Solid Shear Walls: They bear both horizontal and vertical loads and are the core components for resisting lateral forces in high-rise buildings.
• Prefabricated Hollow Walls: The hollow interiors can be filled with insulation materials, combining structural and energy-saving functions.
• Prefabricated Composite Shear Walls: Prefabricated on both sides and cast in place in the middle, they improve construction efficiency and seismic performance.
• Prefabricated Non-load-bearing Walls: Such as partition walls and separating walls, they are lightweight and strong, optimizing indoor space layout.

4. Prefabricated Columns

• Prefabricated Solid Columns: Used for the core load-bearing columns in frame structures to ensure the vertical stability of the building.
• Prefabricated Hollow Columns: They reduce self-weight and are easy to hoist, suitable for large-span public buildings.

5. Prefabricated Stairs and Other Special-shaped Components

• Prefabricated Stair Flights: Including treads and landing slabs, they are produced in a standardized manner with high installation accuracy.
• Prefabricated Integrated Kitchens/Bathrooms: They integrate pipelines, equipment, and decorative finishes, enabling a "move-in ready" installation.
• Prefabricated Bay Windows and Air-conditioning Panels: Prefabricated in factories for exterior window sills and air-conditioning units, they enhance the overall appearance of the building facade.

Application Advantages: Prefabricated components are produced in factories in a standardized manner, reducing on-site wet work and dust pollution. At the same time, precise molds are used to control dimensional deviations, improving building quality. Currently, many domestic enterprises have established prefabricated component libraries, enabling visual selection and customized design through Building Information Modeling (BIM) technology.
