Prefabricated Assembled House Production
Prefabricated assembled house production involves the industrial production of building components, which are then assembled on-site. Common techniques include prefabricated concrete structures and steel structures, with components covering prefabricated products such as beams, slabs, walls, and columns. The specific process varies depending on the material and structural type.
Take container houses as an example. Their production process is highly standardized. In the factory, metal sheets are cut, welded, and treated for corrosion resistance, and then assembled into standard container modules. Inside the modules, processes such as pipeline embedding and thermal insulation layer installation can be completed simultaneously. After module manufacturing, they are transported to the site using specialized transportation tools and quickly stacked and assembled using cranes. Usually, the main structure can be erected within a few hours to a few days. The advantages of this process lie in high production efficiency, reusable modules, and a short on-site construction period.
The construction of reinforced concrete prefabricated houses relies on the collaboration of manual labor and machinery. In the factory, steel reinforcement cages are bound into shape using automated equipment. After concrete pouring, steam curing is applied to achieve the designed strength, forming components such as wall panels and floor slabs. On the construction site, cranes vertically lift the prefabricated wall panels to the designated positions. Workers use laser levels and special brackets to adjust the verticality and levelness, ensuring precise alignment of the components. Subsequently, high-pressure grouting technology is used to fill the gaps between the wall panels, forming an overall load-bearing structure. The advantages of such houses are structural stability and strong durability, but strict control over the accuracy of component transportation and lifting is required.
Some prefabricated houses adopt the mortise-and-tenon jointing process, such as in rural small villa projects. During the foundation construction phase, 5-ton concrete piles are fixed with base plates to form a stable foundation. Prefabricated concrete components are used for beams and columns, which are quickly connected through mortises and tenons, reducing on-site welding or bolt connection processes. Components such as stairs and floor slabs are lifted and installed as a whole using cranes. After paving, the gaps are grouted to ensure structural tightness. This process combines traditional wooden construction wisdom with modern material technology, allowing the main structure to be completed in 14 days, offering both construction efficiency and cost-effectiveness.
Regardless of the technology used, the core of prefabricated assembled houses lies in the combination of industrial production of components and precise on-site assembly. Through standardized design, modular manufacturing, and prefabricated construction, the construction period can be significantly shortened, labor costs reduced, and environmental pollution caused by on-site wet operations minimized.
