Housing Characteristics
The prefabricated cement houses popular in Henan are typical representatives of prefabricated assembly-type houses in Yingyang City. All components of these houses are pre-cast in factories, with the main structure made of reinforced concrete. After the foundation is laid on the homestead, a crane and a few workers can assemble the main structure of a 200-square-meter house in as little as four hours. The basic rough unit price is around 300 yuan per square meter, meaning the main structure of a 100-square-meter house can be completed for just over 30,000 yuan, significantly reducing material and labor costs and alleviating the housing construction burden on ordinary farmers. The manufacturer provides a standard service life of 70 years. Civil engineering professionals state that the standardized factory-produced components have satisfactory durability, and as long as the foundation is stable and the joints are properly sealed, the houses are fully suitable for daily living. In addition to self-occupancy, they can also be used as dormitories and small office buildings, with a maximum of five stories. However, they have shortcomings. If the joints are not properly constructed, there may be water leakage risks later on. Their seismic performance is inferior to that of monolithic cast-in-place houses, and they are not recommended for high-seismic zones. Additionally, interior decoration and water and electricity installations require additional investment by the homeowners.
Policy Support
The Provincial Housing and Urban-Rural Development Department serves as the "one-on-one" assistance unit for post-disaster reconstruction in Yingyang City. The department's Science and Technology and Standards Division has provided on-site technical guidance for the assembly-type buildings in Wangzongdian Village multiple times. The department's Rural Construction Division has led experts to inspect the progress, quality, and safety of村民 (villagers') housing projects more than ten times, working together to advance the development of assembly-type building projects in Yingyang City's post-disaster reconstruction efforts.
