What Type of House Structure Does Prefabricated Panel Belong To

Prefabricated panels are components in prefabricated buildings and need to be combined with load-bearing structures such as frames and brick-concrete structures to form a complete housing system. They are not an independent structural type in themselves.

Definition and Core Attributes of Prefabricated Panels

Prefabricated panels are building components pre-manufactured in factories through industrial production methods, primarily used as horizontal or vertical load-bearing elements such as floor slabs and wall panels. Their core feature is "prefabrication + on-site assembly," meaning that after the components are cast and cured in the factory, they are transported to the construction site for rapid assembly through splicing and connection methods. This production model significantly improves construction efficiency, reduces the amount of on-site wet work, and aligns with the development trend of building industrialization.

Application Scenarios and Structural Types of Prefabricated Panels

Prefabricated panels are mainly used in prefabricated buildings, which achieve overall structural functionality through the combination of standardized components. Depending on the assembly method, prefabricated buildings can be divided into three categories:

1. Panel Assembly: Using prefabricated panels (such as floor slabs and wall panels) as the main components, they are combined with frames or load-bearing walls through connectors to form the enclosure and load-bearing system of the building.
2. Box Assembly: Using three-dimensional spatial modules (such as integrated bathrooms and kitchens) as units, prefabricated panels participate in the assembly as components of the modules.
3. Frame Assembly: Using prefabricated frames (such as beams and columns) as the load-bearing structure, prefabricated panels serve as floor or roof filling materials, jointly forming the overall structure.

Technical Classification and Materials of Prefabricated Panels

From a technical perspective, prefabricated panels involve two mainstream structural systems:

• Prefabricated Concrete Structures: Using reinforced concrete or prestressed concrete prefabricated panels, they are fixed to the main structure through wet connections (such as cast-in-place nodes) or dry connections (such as bolts and welding).
• Prefabricated Steel Structures: Supported by lightweight steel frames and paired with lightweight prefabricated panels (such as profiled steel sheet composite panels), they are suitable for large-span or high-rise buildings.

Role Positioning and Limitations of Prefabricated Panels

It should be clarified that prefabricated panels are construction materials rather than an independent structural system. Their functionality depends on collaborative work with load-bearing structures such as frames and brick-concrete structures:

• In frame structures, prefabricated panels only serve as media for transferring floor or roof loads and do not participate in overall lateral force resistance.
• In brick-concrete structures, prefabricated panels need to be connected to masonry walls through reserved reinforcement or cast-in-place bands to ensure structural integrity.

If used independently without load-bearing structures, prefabricated panels cannot meet basic requirements such as building stability and earthquake resistance. Therefore, their design, production, and installation must strictly adhere to structural codes to ensure compatibility with the main structure.
