Jiuquan Cement Prefabricated House
Jiuquan cement prefabricated houses are prefabricated buildings with reinforced concrete prefabricated components as the main body, featuring short construction periods and stable structural performance, suitable for the climatic conditions in northwest China.
I. Typical Construction Plan and Structural Characteristics
The cement movable house project in the Industrial Park of Suzhou District, Jiuquan City, Gansu Province, serves as a typical case. It has a total construction area of 8,600 square meters, including 68 single-story houses and supporting facilities. Its core structure adopts a reinforced concrete prefabricated assembly system. Each standard house measures 3.5m×7.0m×3.0m (width×length×height), with a designed service life of 15 years, a seismic fortification intensity of 7 degrees, and a basic wind pressure of 0.65kN/㎡, meeting the climatic adaptability requirements of the northwest region with large temperature differences and frequent sandstorms. The total project duration is only 90 days, demonstrating the advantage of rapid assembly of prefabricated components. The main functions cover office areas, living areas, and storage areas.
II. Technical Characteristics of Lightweight Partition Panels
As an important part of prefabricated components, the Jiuquan cement lightweight partition panels are composed of cement, lightweight aggregates, fiber-reinforced materials, and auxiliary additives. By using physical or chemical foaming techniques to reduce material density, their weight is 30%-50% lighter than that of traditional concrete walls, significantly reducing the building's self-weight and the load on the foundation and main structure. In terms of thermal and acoustic performance, their microscopic porous structure provides heat and sound insulation capabilities. During construction, factory prefabrication and on-site assembly methods are adopted, resulting in high installation efficiency and minimal wet work, aligning with the concept of green buildings. Additionally, industrial waste residues can be partially utilized as raw materials, and production energy consumption is low. However, strict control of moisture content and freeze-thaw resistance is required to adapt to the dry climate and large temperature differences between day and night in the Jiuquan area.
III. Pricing and Customized Services
The prices of cement prefabricated houses vary by region and manufacturer. For example, Jining Xiangyun Prefabricated Building Co., Ltd. in Jining, Shandong, quotes 280 yuan per square meter for its integrated cement and concrete houses, while Shijiazhuang Xinwang Building Components Co., Ltd. in Shijiazhuang, Hebei, quotes 100 yuan per square meter for its cement movable houses. The actual price needs to be determined based on a combination of house specifications, functional requirements, and transportation costs. It is recommended to contact local manufacturers for detailed plans.
IV. Application Advantages and Limitations
In terms of advantages, prefabricated houses have short construction periods and strong structural stability, and lightweight partition panels can improve building energy efficiency and construction efficiency. The limitations lie in the high requirements for the freeze-thaw resistance of the panels, which necessitate optimizing the material formula or applying surface protective treatments to ensure long-term durability.
