Cement Prefabricated House in Henan
The cement "prefabricated houses" used in rural areas of Henan are mainly made of reinforced concrete structures, featuring fast construction speed, relatively low prices, and long quality guarantee periods, but their seismic performance is slightly weaker compared to cast-in-place houses.
Construction Speed and Price: Cement "prefabricated houses" are constructed using a factory-prefabricated and on-site assembly method, resulting in extremely fast construction. For example, a cement "prefabricated house" of about 200 square meters can have its main structure erected in just 4 hours and the entire building completed within two days. Their prices are relatively affordable, at around 300 yuan per square meter, making them suitable for rapid construction needs in rural areas.
Quality and Durability: The quality guarantee period for cement "prefabricated houses" is 70 years. The modules themselves are made of reinforced concrete structures, offering strong durability and are unlikely to have quality issues under normal use. However, attention should be paid to the design of the module joints; if the assembly process is not well-executed, it may affect the overall structural stability.
Applicable Scenarios and Floor Limitations: Cement "prefabricated houses" can be built up to 5 floors and are suitable for projects such as rural residences, dormitories, and office buildings. Manufacturers like "Sanzhiniu Cement Houses" are headquartered in Kaifeng City, Henan, and offer a variety of prefabricated house specifications. Additionally, there are brands in Henan such as Hengqi, Xinsheng, and Dingshun, with materials including cement, color steel, concrete, and sandwich panels, and processes covering welding and prefabrication, offering a diverse range of styles.
Seismic Performance and Limitations: Experts point out that the modules of cement "prefabricated houses" do not have durability issues, but their seismic performance is slightly weaker compared to cast-in-place houses. Therefore, they can meet the needs in non-seismic zones but should be chosen with caution in earthquake-prone areas. Furthermore, due to the characteristics of the assembled structure, such houses should not be built with too many floors to ensure safety.
