Assembly of Prefabricated Houses in Rural Xingtai

The assembly of prefabricated houses in rural Xingtai mainly adopts the construction method of prefabricated rural houses, achieving efficient construction through standardized production of prefabricated components and rapid on-site assembly, with advantages in technology, policy, and market aspects.

Construction Method and Technical Characteristics

The main structure of prefabricated rural houses is built using prefabricated components (such as prefabricated concrete wall panels and light steel structural frames) and parts (such as insulation layers and decorative layers), or through construction methods like formwork-free and non-demolition formwork. During construction, prefabricated wall panels are precisely assembled into the house frame by cranes, and workers only need to handle details such as joint grouting and pipeline embedding. The entire process is similar to industrial assembly, significantly reducing on-site wet operations and labor dependence. For example, the construction period for a 120-square-meter prefabricated rural house is only 45 days, which is 30%-50% shorter than that of traditional buildings.

Significant Technical Advantages

1. Energy Efficiency and Insulation: The exterior walls adopt a composite structure of "prefabricated concrete wall panels + insulation layers + decorative layers", with a thermal conductivity coefficient more than 40% lower than that of traditional brick walls. Heating energy consumption in winter is reduced by 30%-50%, and air conditioning load in summer is reduced by more than 20%. For example, the winter heating costs for Qu Liangbin's family in Xiwang Village, Renze District, have decreased by 30%, with a stable indoor temperature of 18°C.
2. Earthquake Resistance and Durability: Light steel structural houses have better earthquake resistance than traditional brick-concrete structures through optimized joint connections and material toughness design, which is in line with the geological characteristics of Xingtai, an area with multiple earthquake zones.
3. Quality Control: Prefabricated components are produced in factories with standardized processes, ensuring high dimensional accuracy and stable quality, reducing on-site construction errors, and enhancing the overall safety of the houses.

Dual Promotion by Policy and Market

1. Policy Support: Since 2022, Xingtai has provided subsidies of approximately 10,000 yuan to pilot farmers constructing prefabricated rural houses, with city-wide promotion and no household limits in 2024. The housing and urban-rural development department has reduced the burden on farmers through government subsidies, enterprise price reductions, and county-level matching subsidies.
2. Market Promotion: Local enterprises (such as Hebei Zhuanzhu Technology Co., Ltd.) have been introduced to achieve standardized production of components, allowing farmers to "select a house type, pay a deposit, and wait for occupancy", simplifying the process. In 2025, 1,049 demonstration households were added, ranking third in the province, forming a "demonstration household driving effect". For example, the prefabricated small building of Zhao Huizhen's family in Dayingshang Village, Ningjin County, has attracted villagers to visit.

Enterprise Participation and Regional Adaptation

Local enterprises have optimized residential designs by considering the climatic characteristics of Xingtai (such as cold winters and rainy summers). For example, the light steel villas of Hebei Zhuanzhu Technology Co., Ltd. adopt thermal insulation materials and wind and rain-resistant structures to enhance living comfort, promoting the upgrade of prefabricated buildings from "functional" to "high-quality".
