Nanning Cement Prefabricated Houses
Cement prefabricated houses in Nanning experienced development in the late 1970s, and currently, there is strict supervision, but limited information is available on their overall development status.
Development from the late 1970s to the mid-to-late 1980s
In the late 1970s, the Guangxi Institute of Architectural Science and Design developed and promoted concrete hollow large-panel prefabricated structural residential buildings, which were also applied in Nanning. Their notable features included fast construction speed, enabling the completion of housing construction within a relatively short period to meet the rapidly increasing demand for housing at that time. Additionally, the cost was relatively low, which was beneficial for controlling construction costs. As a result, they were once widely used in Nanning. However, this structure also had some obvious drawbacks, such as poor sound insulation and thermal insulation performance, which affected the comfort of living. There were also many issues in terms of use and maintenance, for example, the connections between components might not be firm enough, and cracks could easily appear, affecting the service life and safety of the houses. By the mid-to-late 1980s, due to the gradual emergence of these problems, this structure was rarely used in Nanning.
Current Quality Supervision Situation
Currently, the Nanning Construction Management Center continuously carries out special inspections on the quality of concrete prefabricated components. The inspection scope covers all construction projects under construction in the city that involve the use of concrete prefabricated components, as well as all concrete prefabricated component production enterprises in the city. The inspection content includes checking the concrete prefabricated components, their factory quality certificates, re-inspection quality test reports, and construction quality situations, etc. Through these strict inspection measures, the quality of construction projects is ensured, and the healthy and stable development of the concrete prefabricated component industry is promoted. This indicates that Nanning has relatively strict quality control over concrete prefabricated components to ensure the safety and reliability of buildings.
Overall Development Status
Although Nanning currently has strict quality supervision over concrete prefabricated components, information on the overall development status of cement prefabricated houses in Nanning, such as whether there are any new cement prefabricated house construction projects currently, whether the adopted technologies and structures have been improved, and the market acceptance, is not mentioned in the given reference information.
