Images of the Construction Process of Prefabricated Houses
Currently, images of the construction process of prefabricated houses cannot be provided directly, but the construction process can be described in detail:
Foundation Construction: Construction begins on an open site, where workers first unload heavy timber from trucks. On the pre-poured concrete foundation, they start building the chassis frame of the house. First, floor joists are laid to provide a supporting structure for subsequent floor installation. Then, prefabricated beam components with white coatings are installed. These components are carefully designed and prefabricated to ensure structural stability. Metal connectors are used to lock the joints during installation, ensuring that all components are firmly connected. Subsequently, large wooden panels are laid to form a solid platform, providing a stable working surface for subsequent construction.
Wall Installation: The prefabricated wall modules are moved onto the built platform. These wall modules have been prefabricated in the factory according to design requirements, with high precision and quality. Workers stand the wall modules upright and align them precisely to ensure the verticality and accurate positioning of the walls. Then, they use nail guns to fix the walls to the floor. As the wall modules are installed, the boundaries of the house gradually transition from a flat surface to a three-dimensional structure, and the initial outline of the house begins to emerge.
Internal Partition Walls and Second-Floor Floor Beams: Indoors, workers cut and assemble partition wall frames according to design requirements, dividing the space into different functional areas. At the same time, second-floor floor beams are laid to provide support for the installation of the second-floor floor, constructing the upper space and transforming the house from a single-story structure to a multi-story one.
Roof Construction: The large triangular trusses are transported to the site. Triangular trusses are the main load-bearing structures of the roof, and their shapes and dimensions are precisely calculated. Ground and roof workers work closely together, using lifting equipment to hoist the trusses and precisely place them on the top beams of the walls, ensuring the stability and safety of the roof structure.
Supplementary Construction Steps from Other Cases: In some cases, the house location is first determined, and a simple foundation is built. Prefabricated components are used to construct the initial chassis frame, and the weight of the frame is ensured by heavy, easily transportable iron blocks. The floor is made up of individual wooden planks spliced together, with a support column standing in the center of the house. Internal components are assembled like building blocks, while external components involve installing doors and windows, the remaining walls, and finally the roof in sequence. In the case of self-built houses in rural South Korea, the foundation is first leveled and a cushion layer is poured. Foundation piles are installed and beams are spliced together, followed by backfilling with soil and pouring the foundation.
