Rural Concrete Prefabricated Houses
Rural concrete prefabricated houses are a type of prefabricated building, referring to rural residential houses that are prefabricated or partially prefabricated with concrete components in a factory and then transported to the construction site for assembly.
Structural Systems and Specifications: Taking the technical guidelines for the construction of prefabricated rural houses issued in Shandong as an example, its structural system includes prefabricated concrete shear wall structural systems, among others, and provides detailed design and construction specifications to ensure structural safety. These specifications set clear requirements for key performance indicators such as earthquake resistance and load-bearing capacity of the houses, providing technical guarantees for the long-term use of rural prefabricated houses.
Material Requirements: The materials used for rural concrete prefabricated houses should be adapted to local conditions and sourced locally whenever possible. Priority should be given to green and economical building materials or recyclable building materials. On the premise of ensuring quality, local building materials should be used preferentially, and high-energy-consuming and excessively polluting materials should be prohibited. For example, some regions promote the use of recycled aggregate concrete and wall materials made from industrial waste residues, which not only reduce costs but also lessen the environmental burden.
Differences in Technical Systems: There are differences in the technical systems of prefabricated houses across different regions. Taking Hunan as an example, among the two standard drawing sets it has issued, the concrete modular technical system features large-volume components and fast on-site installation, with simple and efficient construction. However, it has high requirements for transportation and lifting, making it suitable for sites with good road conditions and on-site lifting space. The concrete wall panel technical system has small-volume components, facilitating transportation and installation, with simple on-site operations and lower requirements for transportation roads, making it more suitable for areas with complex terrain or poor transportation.
Construction Advantages: Prefabricated green rural houses adopt a factory-prefabricated and on-site-assembled model, allowing the main structure to be erected in just a few days. The connection nodes provided are simple in construction and easy to operate, without the need for complex tools, significantly lowering the technical threshold for on-site construction. This model not only shortens the construction period but also reduces on-site wet operations, lowering dust and noise pollution.
Market Applications: Prefabricated houses also have a certain popularity in the European and American markets. Factories in the Pearl River Delta region of China dismantle reinforced concrete houses into modules, produce them on an assembly line, and then package and ship them abroad. Local residents can move in by simply assembling the modules like building blocks, with a set costing around 200,000 RMB. This model provides a reference for the international promotion of rural prefabricated houses.
