Xuejiawan Concrete Prefabricated Houses

Currently, no complete case of concrete prefabricated houses in Xuejiawan has been retrieved, but the local production conditions, technical standards, and industry practices can support the feasibility of its industrialized construction.

I. Production Capacity Supports Industrialized Construction

The Xuejiawan area has the capacity for large-scale production of concrete prefabricated components. For example, a specific concrete product construction project includes three major categories: drainage ditch covers for municipal roads (C30 concrete), bridge bearing pads (C40 high-performance concrete), and prefabricated beams for building structures (C50 prestressed concrete), with a total production volume of approximately 8,000 cubic meters. It is equipped with two fully automatic production lines and steam curing facilities. Such production lines can be directly used to produce wall panels, floor slabs, stairs, and other components for concrete prefabricated houses by adjusting molds and process parameters, enabling industrialized mass production.

II. Technical Standards Ensure Component Quality

The production of prefabricated components must follow strict process procedures:

• Mold Processing: The surface roughness must be controlled at Ra ≤ 1.6 μm to ensure dimensional accuracy and surface smoothness of the components;
• Steel Bar Processing: The tensile control stress of prestressed steel strands must reach σcon = 1,395 MPa to ensure the crack resistance of the components;
• Concrete Construction: Compulsory mixing for 90 seconds is adopted to ensure material uniformity; steam curing at a constant temperature for 4 hours accelerates the development of concrete strength and shortens the production cycle.
  These standards are aligned with the national standard for ready-mixed concrete and building structure specifications, providing technical guarantees for the durability and seismic resistance of prefabricated houses.

III. Industry Practices Provide Design References

The rental services for integrated houses and movable panel houses in the Xuejiawan area adopt modular designs. Their layered structures (metal/cement fiberboard outer layers, rock wool or polyurethane foam insulation layers, moisture-proof layers, and interior decorative panels) share similarities with the industrialized construction logic of concrete prefabricated houses. For example, concrete prefabricated houses can achieve rapid deployment and functional integration through on-site assembly of prefabricated wall panels and floor slabs, combined with layered designs for insulation and moisture resistance. Additionally, the high standards set by the Beishan Yunjing residential community project for concrete suppliers (an annual production capacity of over 100,000 cubic meters, 120 m³/h mixing equipment, and CMA-certified laboratories) further validate the support capacity of the local material supply system for the construction of prefabricated houses.

For specific cases or enterprise information, it is recommended to supplement the search with local construction enterprise directories or project cases from prefabricated component manufacturers.
