Prefabricated House Construction Process Video
The construction process video of prefabricated houses typically showcases the following key steps. The complete process can be viewed through real-time recordings with titles such as 'Full Process of Prefabricated Modular Housing' or '14 Days to Complete Main Structure Construction':
1. Foundation Treatment
At the beginning of construction, the site needs to be leveled, and debris cleared before pouring a concrete垫层 (sub-base). In some cases, instead of using traditional steel reinforcement, a white plastic sheet is laid as a moisture barrier to reduce the impact of moisture penetration on the foundation. Subsequently, heavy prefabricated foundation piles, each weighing about 5 tons, are installed and fixed to the ground with base plates and expansion screws to ensure overall stability. This step provides a solid foundation for the house and requires strict control over the verticality and connection strength of the piles.
2. Frame Construction
Using cranes, prefabricated beams and wall modules are lifted and quickly connected through mortise-and-tenon joints or metal connectors to form the main frame of the house. Components such as stairs are designed in a standardized manner, and the installation process is similar to 'building blocks'. In some cases, the second-floor frame can be assembled within half a day. During this stage, it is crucial to check the sealing of the module joints to prevent water leakage or air infiltration in the later stages.
3. Floor and Sealing
After laying 5-centimeter-thick prefabricated floor slabs, foam sealant is used to fill the gaps between modules to prevent dust and insects from entering. Subsequently, secondary grouting or cement sealing is performed at the joints to enhance the overall structural integrity. In some cases, soundproofing materials are also laid on the floor surface to improve living comfort. This step requires ensuring that the sealing material is evenly filled to avoid local voids that could affect load-bearing capacity.
4. Roof and Reinforcement
Triangular trusses are lifted and installed as the roof frame, forming a stable triangular structure. A steel mesh is then laid, and the entire roof is poured with concrete. This design effectively disperses wind and snow loads and enhances resistance to deformation. In some cases, solar panels or waterproof layers are also installed on the roof to improve functionality and durability. During roof construction, attention should be paid to the curing time of the concrete to avoid cracking due to premature loading.
