Prefabricated Construction of Entire House
Prefabricated construction of an entire house involves breaking down the building into independent modules, which are manufactured in a factory and then transported to the site for assembly into a finished structure. Details are as follows:
Module Prefabrication Process: The ceiling, floor, water and electricity pipelines, walls, and bathroom waterproof layers of the house are all prefabricated on the factory assembly line. Taking exterior wall panels as an example, the reverse-casting process is used. First, tiles are laid on the formwork, followed by steel bar binding and concrete pouring. After the concrete cures and takes shape, the prefabricated wall panels are erected, and the tile gaps are treated. The components are then steam-cured, demolded, lifted, numbered, and stored in categories.
Production Advantages: The factory adopts parallel operations, combined with automated three-dimensional warehouses and intelligent production lines. Compared to traditional construction, the construction period of modular buildings can be significantly shortened by more than 60%. For example, the China State Construction Hailong Intelligent Construction Industrial Park can deliver 20,000 to 30,000 modules annually, demonstrating extremely high production efficiency.
On-site Assembly Characteristics: After the prefabricated modules are transported to the site, they are assembled like building blocks. Each 'block' has a detailed 'ID card' containing information such as the project name, product model, and production date. Moreover, the position of each steel bar must be precisely located, with errors and precision controlled in millimeters to ensure the quality and stability of the assembly.
Special Types: In addition to conventional prefabricated modular houses, there are also foldable prefabricated houses. These are fully interior-finished and system-integrated in the factory, can be folded and packed into containers for transportation, and can be quickly unfolded and used on-site. For example, an American couple purchased a 73-square-meter, fully furnished two-bedroom prefabricated house online from China. During installation, they only needed to unfold it on the ground and connect the water and electricity to move in, greatly facilitating transportation and installation and making it suitable for scenarios requiring rapid setup.
