Prefabricated House Construction Methods

The construction methods for prefabricated houses mainly include five steps: factory-prefabricated components, ground leveling and cushion pouring, foundation pile installation and beam assembly, on-site module assembly, and soil backfilling and subsequent treatment.

Factory-prefabricated components: This is the foundational step in the construction of prefabricated houses. The entire building is disassembled into multiple independent modules, which are then manufactured in a factory. These prefabricated components cover all parts of the building, including beams, slabs, walls, columns, and even ceilings, floors, and water and electricity pipelines, all of which are fully prefabricated in the factory. The industrial production mode in the factory ensures stable component quality and high production efficiency, providing a reliable guarantee for subsequent on-site assembly.

Ground leveling and cushion pouring: At the construction site, the first step is to clear away weeds and other debris from the site, and then excavate the foundation pit. Through precise measurements, ensure that the excavation depth and ground height meet the design requirements. To prevent water loss from the concrete during pouring, a white plastic sheet is laid on the ground. After that, a concrete pump truck is used to pour concrete into the foundation pit, forming a stable foundation.

Foundation pile installation and beam assembly: After the concrete has set, install the foundation plates, drill holes using a drill, and secure them with expansion screws. Then, use a mobile crane to install the prefabricated foundation piles, which weigh about 5 tons each, into place. The foundation piles have reserved holes for subsequent lifting operations. After the foundation piles are installed, assemble the beams like building blocks, adjusting them through level measurements to ensure they are horizontal, then securing them with nuts, filling the gaps with foam, and finally sealing the nut fixation points with cement to ensure structural stability.

On-site module assembly: Transport the prefabricated modules to the construction site and assemble them like building blocks using equipment such as tower cranes. Each module has a detailed 'ID card' that includes information such as the project name, product model, and production date, facilitating management and traceability. During assembly, high-precision positioning technology is used to strictly control errors and ensure the overall structural accuracy of the house.

Soil backfilling and subsequent treatment: After completing the foundation frame structure, perform soil backfilling operations. Some projects also carry out on-site cast-in-place connection modules to enhance the overall integrity and stability of the house. Finally, perform grouting treatment on the gaps between all components to further improve the house's airtightness and durability.
