Installation of Prefabricated Houses

The installation of prefabricated houses adopts a modular construction model, achieving efficient construction through factory-prefabricated core components and on-site assembly of modules, offering advantages such as short construction periods and controllable quality.

Factory Prefabrication: Standardized Production of Core Components

The foundation of the installation of prefabricated houses lies in the factory prefabrication process. Core components such as ceilings, floors, walls, and water and electricity pipelines are all prefabricated on factory assembly lines. Some projects utilize automated vertical warehouses and intelligent production lines to shorten construction periods through parallel operations. For example, the prefabricated modules of a real estate project in Shanghai are equipped with 'ID cards' (containing project names, product models, and other information), ensuring traceability of component information and providing a basis for subsequent precise assembly. Factory prefabrication not only improves the standardization of components but also reduces error sources in on-site construction through centralized production, ensuring overall quality.

On-Site Assembly: Modular Assembly Achieving Millimeter-Level Precision

After being transported to the construction site by equipment such as tower cranes, prefabricated modules are assembled like building blocks. Taking a real estate project in Shanghai as an example, its prefabricated modules achieve millimeter-level error control through precise positioning technology, ensuring tight connections and stable structures between modules. This assembly method significantly reduces on-site wet operations (such as concrete pouring), reduces dependence on weather conditions, and minimizes construction noise and dust pollution. A public housing project in Shenzhen used 6,028 concrete modules for assembly, shortening the completion and delivery period from the traditional 2.5-3 years to 1 year through modular construction, and reducing on-site labor by approximately 50%, fully demonstrating the efficiency of the assembly process.

Efficiency and Technological Advantages: Shortened Construction Period and Improved Quality

Compared to traditional construction, modular construction can shorten the construction period by more than 60%. The case of the public housing project in Shenzhen demonstrates that modular construction significantly shortens the overall construction period through the coordination of factory prefabrication and on-site assembly. Additionally, the controlled environment of factory prefabrication ensures easier quality control of components, avoiding quality fluctuations caused by human factors in on-site construction. Meanwhile, the modular construction model requires high standards for transportation and lifting equipment and needs support from technological systems, production systems, and industrial clusters. However, its advantages of short construction periods, controllable quality, and energy efficiency and environmental protection make it an important development direction in the modern construction field.
