Prefabricated House Structural Diagram

Currently, a direct prefabricated house structural diagram cannot be provided, but we can introduce the common structural types and characteristics of prefabricated houses.

Prefabricated houses are mainly divided into the following structural types based on their component forms and assembly methods:

1. Prefabricated Panel House Structure
Prefabricated panel houses use prefabricated panels as the main load-bearing components, which are divided into solid and hollow types. Hollow prefabricated panels achieve lightweighting by reducing the amount of concrete in non-load-bearing parts while maintaining structural strength. The floors of such houses are usually assembled from multiple prefabricated panels, and the horizontal and vertical joints between the panels need to be filled with fine aggregate concrete or cement mortar to ensure overall stability. The advantages of prefabricated panel houses include fast construction speed and lower cost, but their sound insulation and thermal insulation performance may be slightly inferior to cast-in-place structures.

2. Prefabricated Building Structure
Prefabricated buildings are further subdivided based on component combinations:

• Block Building: Small prefabricated components (such as blocks) are produced in the factory and then transported to the site for assembly into complete walls or floors, suitable for low-rise residential buildings.
• Panel Building: Some integral components of the prefabricated house (such as facades and floor slabs) are completed in the factory, and only fixed connections are required on-site, commonly found in multi-story apartments or office buildings.
• Box Building: A single room (including hard finishes) is assembled as a whole in the factory and then transported for direct on-site assembly, suitable for standardized dormitories or hotels.
• Skeleton Panel Building: The main skeleton of the building (such as steel beams and columns) is divided into prefabricated parts, manufactured in the factory and then assembled on-site, followed by the installation of prefabricated panels to form walls and floors, offering high flexibility.
• Lifting Floor and Storey Building: Using jacks and concrete columns, the floor slab cast on the ground floor is gradually lifted to the predetermined height, reducing the risk of high-altitude operations and suitable for high-rise buildings.

3. Prefabricated Hollow Panels in Brick-Concrete Structures
In traditional brick-concrete structures, prefabricated hollow panels are often used for floors. This structure is formed by horizontally or vertically splicing multiple prefabricated panels, with the gaps filled with fine aggregate concrete to create a continuous floor. Its advantage lies in high construction efficiency, but attention must be paid to panel joint treatment to avoid cracking issues.

The structural design of prefabricated houses must comprehensively consider transportation limitations, on-site assembly accuracy, and seismic performance. In actual projects, structural diagrams are usually drawn by professional design institutes based on building functions, load requirements, and local regulations, including detailed information such as floor plans, component dimensions, and connection nodes. For specific drawings, it is recommended to contact the manufacturer or design unit of the prefabricated house.
