Prefabricated House: Cement Prefabricated Housing

Prefabricated cement housing is a construction method that divides a house into multiple components, which are prefabricated in a factory and then transported to the site for installation and fixation. This approach offers advantages such as efficiency, cost-effectiveness, and structural reliability.

Efficient and Convenient Construction Process
The construction process of cement prefabricated housing resembles building with "building blocks." Components such as wall panels, floor slabs, and stairs are standardized and produced in a factory, and only assembly is required on-site to complete the main structure. For example, in a practical case in Henan, a few workers, with the assistance of a crane, can assemble a complete house in just a few hours or even as little as 4 hours. In a South Korean case, a construction team completed a building in 14 days, with the second-floor frame taking shape within half a day. This model significantly shortens the construction period, making it particularly suitable for projects with tight time constraints.

Significant Cost Advantages
The cost of prefabricated housing is relatively low, with an average price of around 300 yuan per square meter. Building a large villa only requires a budget of tens of thousands of yuan. Taking a 200-square-meter house as an example, the rough construction cost is approximately 60,000 yuan, which is much lower than that of traditional brick-and-mortar structures. The cost advantages stem from reduced material waste due to factory-scale production, lower labor costs, and indirect cost savings from shortened construction periods.

Reliable Structure and Wide Applicability
The main structure is mostly made of reinforced concrete, ensuring precise component dimensions and adequate strength through accurate calculations and mold forming. The quality guarantee period extends up to 70 years, and the structure can withstand natural disasters such as earthquakes. Its wide applicability makes it suitable for various scenarios, including residential buildings, dormitories, and office buildings, with the ability to construct buildings up to 5 stories high, meeting diverse needs.

Standardized Construction Process
Taking a South Korean case as an example, the foundation construction involves laying plastic sheeting, pouring an unreinforced concrete垫层 (sub-base), and then lifting and installing foundation piles before backfilling with insulation and moisture-proof materials. During main structure installation, load-bearing columns and beams are connected through protrusions and grooves, secured with nuts, and then reinforced with secondary grouting. After floor slab installation, foam sealant is used to seal gaps, and a steel mesh is laid before pouring concrete to form an integrated structure. Standardized processes reduce on-site wet work, improving construction quality and efficiency.
