Chongqing Cement Prefabricated Houses
Chongqing has cement prefabricated house-related products and manufacturers, with numerous advantages.
Product Production Status: The Hechuan branch in Chongqing is producing prefabricated cement houses using large steel molds for one-time pouring and forming, with C35 commercial concrete. Additionally, on Baidu's B2B platform, Aicai.com, there is information on wholesale prices for prefabricated cement integrated houses in Chongqing, and product information on cement prefabricated houses in Chongqing is also displayed, indicating that the local cement prefabricated housing industry has a certain scale and market activity.
Safety Performance Advantages: The outstanding safety performance of prefabricated cement houses stems from the robust design of the "full-frame shear wall". Using Φ10 - Φ14 national standard threaded steel bars to construct the framework, combined with C35 concrete for integral pouring, each module weighs over 20 tons, with wall thicknesses ranging from 150 - 200mm and floor thickness of 120mm. This structure enables it to withstand earthquakes of magnitude 8 (with a designed seismic fortification intensity of 7 degrees), remain stable under typhoons of force 12 with no loosening of the prestressed bolts between modules, and has a fire resistance limit of over 3 hours for the concrete, providing reliable safety protection for occupants.
Construction Efficiency Advantages: Compared to traditional self-built houses, the construction efficiency of cement houses is significantly improved. Traditional self-built houses have construction periods ranging from 3 to 6 months, whereas cement houses adopt a "factory production + on-site assembly" model, with the overall installation of a 100㎡ house taking only 1 day, reducing the construction time by 90% compared to traditional methods. Moreover, the modules have pre-embedded water and electricity pipelines before leaving the factory, allowing for immediate use upon on-site connection, reducing the complexity and time cost of on-site construction, and greatly shortening the cycle for house delivery and use.
