Yanji Cement Prefabricated House

Yanji cement prefabricated houses are prefabricated buildings with reinforced concrete or monolithic casting materials as the main body. They have the characteristics of rapid construction, cost-effectiveness, and durability, and are suitable for rural self-built houses and temporary housing in non-seismic zones.

Construction Technology and Structural Characteristics

Prefabricated cement houses in the Yanbian region mainly adopt two processes:

1. Modular Assembly: Represented by "Sanzhiniu Cement Houses," the main structure is made of reinforced concrete. Standardized components are produced in factories and then assembled on-site. For example, a 200-square-meter house can be built in as little as 4 hours. The joints between modules are filled with high-strength mortar, resulting in significantly higher construction efficiency compared to traditional buildings.
2. Monolithic Casting: Products from Huacheng Cement House Factory, for instance, achieve structural integration through one-time casting processes. They possess properties such as earthquake resistance, compression resistance, fire resistance, and flame retardancy, with a design lifespan exceeding 70 years. These houses support overall relocation and secondary disassembly and assembly, offering greater flexibility.

Performance and Suitable Scenarios

• Durability: Prefabricated components are produced in factories under standardized conditions, ensuring quality control. The warranty period generally reaches 70 years, with low maintenance costs.
• Earthquake Resistance: The modular assembly structure requires special optimization of joint designs. Experts recommend prioritizing their use in non-seismic zones. The monolithic casting process, due to its stronger structural continuity, offers superior earthquake resistance.
• Cost-Effectiveness: Taking "Sanzhiniu Cement Houses" as an example, the cost per square meter is 300 yuan, significantly lower than that of traditional brick-and-mortar structures. Additionally, the short construction period reduces labor and material waste.
• Application Scenarios: Suitable for rural renovations, rural self-built houses, temporary housing on construction sites, etc. Huacheng Cement House Factory also provides customized services to meet different functional requirements.

Market and Enterprise Status

Currently, the prefabricated cement house market in the Yanbian region is dominated by operating enterprises such as "Sanzhiniu Cement Houses" and Huacheng Cement House Factory. Technical standards can be referenced from their publicly available information. Although the Prefabricated Component Factory of Yanji City Housing Construction Engineering Co., Ltd. was once involved in this field, it has been revoked and does not affect the existing market landscape.

Precautions

• Regional Restrictions: Modular assembly houses should avoid seismic zones, while monolithic casting houses have broader applicability.
• Joint Design: Modular houses must ensure the strength of joints to avoid structural risks caused by mortar aging.
• Compliance: When selecting an enterprise, verify its qualifications to ensure that the products comply with local building codes.
