Puyang Prefabricated Modular Housing
The prefabricated modular housing in Puyang comes in a variety of types, including reinforced concrete modular houses and innovative folding houses, characterized by their stable structures and innovative functions.
Puyang Fanzhai's modular houses adopt a three-story, four-roof structure, which is essentially a reinforced concrete structure. This structure forms a high-strength load-bearing system through the synergistic action of steel bars and concrete, meeting the mechanical requirements of multi-story buildings. Meanwhile, the houses are equipped with internal and external insulation layers. The external insulation layer typically uses materials such as polystyrene boards or rock wool boards, effectively reducing heat transfer and lowering energy consumption for winter heating and summer cooling. The internal insulation layer further optimizes the indoor thermal environment, enhancing living comfort. The construction process of these modular houses emphasizes standardization, with components prefabricated in factories and then transported to the site for assembly, reducing on-site wet work and shortening the construction period.
The modular houses in Qingzu Fanzhai Village adopt a shear wall design with insulation, also a fully reinforced concrete structure. As the main lateral force-resisting components, shear walls can withstand horizontal loads (such as wind loads and seismic actions), enhancing the overall stability of the houses. The combined design of the insulation layer and shear walls ensures both structural safety and energy efficiency. The connections between components in these modular houses typically use high-strength bolts or welding processes, ensuring that the mechanical properties at the joints are consistent with the overall structure, making them suitable for areas with high seismic and wind resistance requirements.
In addition, Puyang has introduced innovative folding houses, with core wall and floor modules prefabricated into movable structures in factories. Through hinge or slide rail systems, these modules can be folded during transportation to reduce space occupation and then fixed to form a complete space using mechanical devices after unfolding. This design integrates structural mechanics, mechanical engineering, and materials science: structural mechanics ensures mechanical balance during folding and unfolding; mechanical engineering provides precise control of hinge and slide rail transmission systems; materials science selects high-strength, lightweight alloys or composite materials, balancing module strength and portability. These houses are suitable for temporary living and emergency rescue scenarios, offering advantages such as rapid deployment and flexible adjustment.
