Rural Foam Prefabricated House Assembly
The assembly of rural foam prefabricated houses primarily employs non-removable insulation formwork technology and prefabricated assembly methods, characterized by rapid construction speed and excellent performance.
Non-removable Insulation Formwork Technology:
The walls are formed by integrating foam panels on both sides with reinforced concrete in the middle. During construction, foam modules resembling large building blocks are interlocked to form the wall framework, which is then filled with concrete. Once the concrete sets, the foam formwork does not need to be removed and serves directly as the insulation layer. This technology simplifies the construction process through modular design, enabling the completion of the main structure of a two-story building in just 3 days, significantly shortening the construction period. Its core advantage lies in the integration of structural and insulation functions: the foam layer provides efficient thermal insulation, making the house warm in winter and cool in summer; the reinforced concrete framework enhances overall seismic resistance, making it particularly suitable for rural areas with complex geological conditions.
Prefabricated Assembly Method:
Represented by the rise of prefabricated rural houses in Hebei, this method adopts a model of factory-prefabricated components combined with on-site assembly. The main structural elements of the house, such as columns, beams, and wall panels, are standardized and produced in factories, then transported to the building site for rapid assembly using bolts or welding, followed by local concrete pouring for fixation. This "LEGO-style" assembly method further improves construction efficiency by eliminating the need for formwork erection and removal in traditional cast-in-place processes, while also reducing construction waste generated by on-site wet operations. Additionally, prefabricated rural houses align with the national promotion of green buildings, with policy subsidies available in some regions, reducing construction costs for farmers.
Technology Comparison and Applicable Scenarios:
Non-removable insulation formwork technology focuses more on the integration of wall insulation and structure, making it suitable for areas with high energy efficiency requirements; the prefabricated assembly method emphasizes component standardization and construction convenience, making it applicable to rural areas with flat terrain and convenient transportation. Both technologies enhance building quality stability through industrialized production, but it is important to note that foam modules should be made of fire-resistant materials to meet fire safety regulations, and the connection nodes of prefabricated components should be strictly controlled for construction quality to avoid structural hazards. With the advancement of the rural revitalization strategy, these technologies are becoming an important direction for rural housing construction.
