Schematic Diagram of Prefabricated Panel House

There is no directly publicly available universal schematic diagram for prefabricated panel houses, but they can be understood through their structural principles and construction logic. A prefabricated panel house is a type of building where building components (such as floor slabs and wall panels) are prefabricated in a factory and then transported to the construction site for assembly. Its core principle lies in the combination of standardized design and modular construction. The following explains it from three aspects: structural composition, construction process, and load-bearing principle:

Structural Composition

The main components of a prefabricated panel house include prefabricated floor slabs, prefabricated wall panels, prefabricated beams, and prefabricated columns. Prefabricated floor slabs are usually made of reinforced concrete, with load-bearing and distribution reinforcements arranged inside. They are cast using molds, with a flat surface and reserved installation holes. Prefabricated wall panels can be divided into solid wall panels and hollow wall panels. Solid wall panels have high strength, while hollow wall panels are lightweight and have good thermal insulation properties. Prefabricated beams and columns bear the main vertical and horizontal loads of the house, and their cross-sectional dimensions and reinforcement are determined according to the design load. After production in the factory, these components undergo quality inspection to ensure that their dimensional accuracy and strength meet the standards.

Construction Process

During construction, foundation work is carried out first, including foundation treatment and foundation pouring, to provide stable support for the house. Subsequently, the prefabricated columns and beams are hoisted to the designated positions and fixed through reserved reinforcements or bolts to form the frame structure of the house. Then, the prefabricated wall panels are installed, and they are connected using special connectors or mortar to ensure the integrity and airtightness of the structure. Finally, the prefabricated floor slabs are laid, and they are reliably connected to the beams through reserved reinforcements or connectors to form a complete floor structure. During the installation process, necessary calibration and adjustment are also required to ensure that the positions of the components are accurate and the perpendicularity meets the requirements.

Load-Bearing Principle

The load-bearing system of a prefabricated panel house is similar to that of a cast-in-place concrete house, but the connection methods between components are different. Under vertical loads, the prefabricated floor slabs transfer the loads to the prefabricated beams, which then transfer the loads to the prefabricated columns, and finally, the foundation bears and transfers the loads to the ground. Under horizontal loads (such as wind loads and seismic actions), the integrity of the house is crucial. The reliable connection between prefabricated components is the key to ensuring the lateral resistance of the house. Through reasonable connection design and construction, the components can work together to resist horizontal loads, ensuring the safety and stability of the house.
