How to Make Prefabricated House Structure

The production of prefabricated house structures primarily adopts a modular construction approach, achieving efficient construction through factory-prefabricated components and on-site assembly, combined with high-precision processes and standardized procedures. The production process can be divided into the following four stages:

I. Modular Design and Factory Prefabrication
The core of prefabricated houses lies in breaking down the building into independent modules, such as ceilings, walls, and bathroom waterproof layers, which are manufactured on factory assembly lines. For example, a hollow model is made using wooden boards, reinforced with steel bars inside, and then filled with cement to form prefabricated panels for insulation layers or gutter covers; the main walls are supported by solid wooden frames. Standardized production is carried out in the factory using automated equipment, with each component labeled with an 'ID card' (including project name, model, and production date) to ensure traceability of quality. The application of high-precision equipment is crucial: laser-printed labels are used to classify and stack wooden boards, robotic arms grab materials along preset trajectories, controlling component errors to within millimeters and reducing the need for on-site adjustments.

II. Foundation Treatment and Basic Construction
The first step in on-site construction is foundation treatment: after leveling the land, a concrete cushion is poured, foundation piles are installed (e.g., 5-ton piles fixed with base plates), and crossbeams are spliced. Mortise-and-tenon joints are widely used for crossbeam connections, with their quick positioning characteristics shortening construction time. The foundation must meet load-bearing requirements, such as using pile foundations or raft foundations in soft soil areas to ensure house stability.

III. Component Hoisting and On-site Assembly
After being transported to the site, components are assembled layer by layer in a 'building block' manner:

1. Structural Installation: First, hoist the main wall frames, then install stairs and floor slabs (e.g., 5 cm thick prefabricated panels), and finally assemble the roof modules.
2. Gap Treatment: After all components are connected, grout the gaps to enhance the overall structural integrity.
3. Precision Verification: Use laser levels and other equipment to monitor verticality and flatness in real-time, ensuring assembly errors meet design standards.

IV. Technical Advantages and Quality Control
The significant advantages of prefabricated houses lie in shortened construction periods and controllable quality:

• Shortened Construction Period: Factory prefabrication and on-site construction proceed in parallel, reducing the construction period by more than 60% compared to traditional buildings.
• Controllable Quality: The factory environment reduces weather interference, and automated production lowers human errors, with parameters such as prefabricated panel thickness and steel bar spacing strictly controlled by equipment.
• Environmental Protection: Modular production reduces on-site construction waste, increasing material utilization by approximately 20%.

Precautions: For prefabricated houses, it is necessary to plan transportation routes and hoisting plans in advance to avoid damage to components during transportation; at the same time, on-site assembly must strictly follow the construction sequence to prevent structural instability caused by incorrect sequencing.
