Sichuan Mianzhu Cement Prefabricated Houses
There are various types of cement prefabricated houses in Mianzhu, Sichuan, each with its own characteristics.
Firstly, customized cement houses are used for rapid villa construction. There are cases in Mianzhu where customized cement houses have been used to quickly build villas. For example, Mr. Hong in Mianzhu customized 11 cement houses to construct a large 370-square-meter villa. The exterior and interior decoration have already begun, and he plans to move in a month later. This demonstrates that cement prefabricated houses have certain advantages in meeting personalized needs and rapid construction, providing a relatively convenient solution for those with housing construction needs. With reasonable planning and construction, it is possible to move into a new home within a relatively short period.
Secondly, prefabricated panel houses built in the 1990s. These houses are widely found on the streets and alleys of Mianzhu. After enduring more than thirty years of weathering and the impact of the May 12 earthquake, their structures have severely deteriorated, with problems such as wall cracking, floor slab loosening, and steel bar corrosion. They pose structural risks and have extremely poor earthquake resistance. The occupants are mostly elderly people, disabled individuals, those with chronic illnesses, and disadvantaged groups. However, current urban renovations often focus on superficial aspects and fail to substantially address the safety issues of these prefabricated panel houses. Therefore, it is essential to conduct a comprehensive inventory, assessment, and renovation of these houses to solve the residents' housing safety problems and protect their lives and property.
Thirdly, the cement "prefabricated houses" manufactured by "Three Cows Cement Houses." These houses have a main structure of reinforced concrete. During construction, the mold size is adjusted according to the owner's needs, and then concrete is poured. High-strength mortar is used to fill the joints between each module. A house of about 200 square meters can be built in as fast as 4 hours, with a charge of 300 yuan per square meter. The quality guarantee period is 70 years, and they can be built up to 5 stories high. However, experts say that while the modules of these "prefabricated houses" do not have durability issues, the key lies in the assembly connections. Compared to cast-in-place houses, their earthquake resistance is slightly inferior. They can meet the needs in non-earthquake zones but should not be built too high, otherwise, they may not meet the earthquake resistance design requirements.
