Prefabricated House On-site Installation Project

The prefabricated house on-site installation project involves transporting independently prefabricated modules from the factory to the construction site for assembly. Here is a detailed introduction:

Factory Prefabrication Phase: Structures such as ceilings, walls, and bathroom waterproofing layers, as well as mechanical and electrical systems, interior finishes, and exterior decorations, are all integrated in the factory. The production mode is similar to that of the automotive industry, where scattered components are first produced separately and then assembled on the final assembly line. Each module has a detailed 'ID card' containing information such as the project name, product model, and production date. The positioning of each steel bar is precise, with errors and precision controlled in millimeters. This refined production method ensures uniform module quality and specifications, laying a solid foundation for subsequent on-site installation.

On-site Installation Phase: At the construction site, several tower cranes are responsible for transporting and installing these prefabricated modules in the appropriate positions. Compared to traditional construction methods, this building approach changes the construction process, enabling simultaneous progress in factory module production and on-site construction.

Significant Advantages:

• Reduced Construction Time: Over 70% of the processes are completed in the factory, reducing the construction period by more than 60%. For example, in a social housing project in Shenzhen, Guangdong, five residential buildings nearly 100 meters high were assembled from 6,028 concrete modules. Compared to traditional construction methods, the completion and delivery time was reduced from 2.5 to 3 years to just 1 year.
• Environmental Protection and Energy Efficiency: It effectively alleviates traffic pressure at the construction site, reduces site occupation, and lowers environmental pollution. Building waste emissions can be reduced by more than 75%, material losses by more than 25%, on-site electricity consumption by more than 60%, and water consumption by more than 66%.
• Enhanced Performance: The building's waterproofing, sound insulation, and earthquake resistance are all significantly improved.
• Flexible Reusability: Modules can be disassembled and stacked, enabling elastic expansion, with a reuse rate exceeding 90%.
• Reduced Labor: On-site labor is reduced, such as in the aforementioned social housing project, where on-site labor was reduced by approximately 50%.
