Ziyang Cement Prefabricated House Construction
The construction of cement prefabricated houses in Ziyang demonstrates the 'Chinese speed' through an efficient industrialized model, with core features reflected in four aspects: factory prefabrication, on-site hoisting, structural safety, and policy support.
1. Factory Prefabrication: Full-process mechanization, balancing precision and efficiency
The production of prefabricated cement houses is completed in standardized workshops using a fully mechanized process involving steel bar binding, mold assembly, and concrete pouring. Each module takes only 7 days to produce, with errors strictly controlled within 2 millimeters, ensuring consistent component dimensions. This industrialized production model not only shortens the construction cycle but also reduces costs through large-scale production while avoiding issues such as weather and labor constraints common in traditional on-site construction.
2. On-site Hoisting: Modular installation, surpassing traditional speed
After being transported to the construction site, components are installed using a 50-ton crane in conjunction with an intelligent positioning system, with the main structure of a single villa taking only 4 hours to assemble. For example, a 100-square-meter house can be made ready for occupancy in just 5 days from an empty lot, reducing the construction period by over 60% compared to traditional brick-and-mortar structures. Modules are connected using a combination of prestressed bolts and traditional Chinese mortise-and-tenon joints, ensuring both connection strength and construction efficiency, truly achieving 'building-block'-style rapid construction.
3. Structural Safety: Outstanding earthquake resistance and superior load-bearing capacity
The houses adopt a full-frame shear wall structure with walls 200 millimeters thick and a compressive strength of up to 30 MPa (equivalent to withstanding 3,000 tons per square meter). In simulated Wenchuan earthquake tests, the overall displacement was only 3 centimeters under 9-degree intensity shaking, far exceeding traditional building seismic standards. The connection method between modules further enhances structural integrity, making them resistant to collapse even if locally damaged, providing dual safety guarantees for occupants.
4. Policy and Industrial Support: Standardized management drives development
The Ziyang Housing and Urban-Rural Development Bureau's notice on the continuation of construction enterprise qualifications provides clear guidance for the qualification management of cement prefabricated house construction companies, ensuring standardized industry development. Meanwhile, local enterprises such as Yiyang Deyu Building Materials Co., Ltd. have established a production and sales system for cement prefabricated components, providing a stable supply chain for construction.
In summary, the construction of cement prefabricated houses in Ziyang achieves a dual improvement in construction efficiency and quality through industrialized production, modular installation, high-strength structures, and policy support, becoming a typical representative of 'Chinese speed' in the modern construction sector.
