Prefabricated Cement Box House
Prefabricated cement box houses are a type of prefabricated assembled building, produced industrially and assembled on-site, featuring efficiency, safety, and environmental friendliness.
Production and Installation
Prefabricated cement box houses are produced through fully mechanized processes on standardized production lines, completing tasks such as steel bar tying, mold assembly, and concrete pouring. The production cycle for a single module is only 7 days, with an error margin controlled within 2 millimeters. On-site installation relies on a 50-ton crane and intelligent positioning systems, allowing the main structure of a single villa to be installed in just 4 hours. A 100㎡ house can be ready for occupancy in just 5 days from an empty lot, significantly shortening the construction period.
Structural Performance
The house adopts a full-frame shear wall structure, using C35 concrete and Φ14 threaded steel bars. The reinforcement ratio of a single module reaches 1.2%, with a wall thickness of 200mm and a compressive strength of 30MPa (capable of withstanding 3,000 tons per square meter). Modules are connected through a dual system of prestressed bolts (with a tensile strength of 25 tons) and mortise-and-tenon joints, resulting in an overall displacement of only 3cm during a simulated 9-degree earthquake, demonstrating excellent seismic performance.
Functional Integration
The walls are embedded with EPS insulation layers (with a thermal conductivity of 0.03W/(m・K)), reducing heating costs by 50% in winter. The roof is equipped with预留 (reserved) photovoltaic panel interfaces, enabling a 200㎡ house to generate up to 3,000 kWh of electricity annually, meeting household electricity needs. Additionally, the house meets special-grade standards for snow load and wind resistance, adapting to various climatic conditions.
Environmental and Economic Advantages
Compared to traditional construction methods, construction waste is reduced by 98% (from 30 tons per building to 0.5 tons per building), labor costs are reduced by 60% (from 60,000 yuan for a 100㎡ house to 24,000 yuan), and construction efficiency is increased by 180 times (from 6 months for a 300㎡ house to just 1 day). Manufacturers in areas such as Zhuozhou, Baoding, Hebei, offer customization services, with prices starting from 255 yuan per square meter, supporting flexible payment methods.
Application Scenarios and Market
The houses are suitable for various scenarios, including rural self-built houses, villas, construction site temporary housing, dormitories, and shops, with a service life of over 50 years. For example, a construction site in Qixian, Henan, completed the main structure of a 200㎡ three-story villa in just 4 hours using this method. During the COVID-19 pandemic in Shenzhen, 300 isolation wards were built in 48 hours. According to customs data, the export value of portable houses in the Guangzhou Customs area reached 1.4 billion yuan in the first four months of 2026, a year-on-year increase of 38.1%, indicating a broad market prospect.
