Prefabricated Simple House Structural Diagram

Currently, a direct prefabricated simple house structural diagram cannot be provided, but the structural composition characteristics can be described based on the types of prefabricated components. Prefabricated simple houses typically adopt a modular design, with standardized prefabricated components quickly assembled to form an overall structure. The core component types and structural logic are as follows:

1. Horizontal load-bearing system: Prefabricated floor slabs and beams
Prefabricated floor slabs are the main load-bearing components in the horizontal direction. Depending on functional requirements, they are classified into solid slabs, hollow slabs, and composite slabs. Solid slabs have high strength but are heavy, suitable for small-span spaces; hollow slabs reduce weight through internal holes and are commonly used for residential floors; composite slabs consist of a prefabricated base slab and a cast-in-place layer, balancing construction efficiency and structural integrity. Prefabricated beams include solid beams, composite beams, and U-shaped beams, which form a reliable load transfer path with floor slabs through pre-embedded reinforcement or connectors, jointly bearing vertical loads. For example, the prefabricated part of a composite beam can be completed in the factory in advance, and only the upper concrete needs to be poured on-site, significantly shortening the construction period.

2. Vertical load-bearing system: Prefabricated walls and columns
Prefabricated walls are divided into load-bearing walls and non-load-bearing walls. Load-bearing walls (such as solid shear walls and composite shear walls) resist lateral forces through high-strength concrete and steel reinforcement skeletons, serving as the core for the house's lateral stability; non-load-bearing walls (such as hollow walls and prefabricated partition walls) mainly function to separate spaces, are lightweight, and easy to install. Prefabricated columns usually adopt solid or hollow designs, connected to the foundation through sleeve grouting and to beams through cast-in-place concrete at the joint area to form a frame structure, ensuring a clear load transfer path for vertical loads. For example, in multi-story prefabricated houses, standardized design of column grid spacing can significantly improve component reusability.

3. Traffic and functional components: Prefabricated stairs and special-shaped parts
Prefabricated stair sections and landings are formed as a whole in the factory and connected to the main structure through pre-reserved bolt holes or welding, avoiding on-site wet work and enhancing construction safety. Complex special-shaped components (such as bay windows and integrated kitchens and bathrooms) integrate pipelines and decorative finishes through integrated design, reducing on-site cross-work. For example, prefabricated air conditioning panels are usually integrated with exterior wall panels and fixed with pre-embedded parts, meeting equipment installation requirements while ensuring a flat exterior facade.

4. Connection joint design: The key to structural safety
The connections between prefabricated components are achieved through mechanical connections (such as sleeve grouting and bolt connections) or post-poured concrete. For example, the connection between a composite slab and a beam requires pre-embedded reinforcement lap lengths and forms an integral whole through the cast-in-place layer; the vertical joints of shear walls are connected using grouting sleeves to ensure reliable performance of the plastic hinge zone under earthquake action. Joint design must strictly comply with code requirements and be verified through tests for load-bearing capacity and deformation capacity.
