Prefabricated Houses in Kaifeng
In Kaifeng, Henan, prefabricated houses have been applied, especially popular in rural areas.
Construction Method and Efficiency of Prefabricated Houses
The walls, floors, roofs, and other components of prefabricated houses are prefabricated in the factory in advance. On-site assembly is as simple as putting together building blocks. For example, a house of about 200 square meters can be built in as fast as 4 hours, greatly shortening the construction cycle and improving construction efficiency.
Cost and Durability of Prefabricated Houses
The cost per square meter of a prefabricated house is approximately 300 yuan, making it more economical compared to traditional construction methods. Its main structure is made of reinforced concrete, and the modules themselves have no durability issues, with a quality guarantee period of up to 70 years, providing residents with a long-term and stable living environment.
Seismic Performance and Applicability of Prefabricated Houses
The seismic performance of prefabricated houses is slightly inferior to that of traditional cast-in-place houses, but in non-seismic zones, their seismic performance can meet basic requirements. Additionally, since the number of floors in prefabricated houses cannot be too high, with a maximum of 5 floors, they are more suitable for low-rise buildings such as rural houses, dormitories, and office buildings.
Prefabricated House Projects in Kaifeng
In the Kaifeng area, companies have undertaken such prefabricated house projects, covering various building types including residential houses, dormitories, and office buildings. These projects not only provide local residents with affordable housing options but also promote innovation and development in the local construction industry.
Situation of Prefabricated Houses in the Renovation of Old Residential Areas in Kaifeng
Although the large panel buildings on Weidu Road in Kaifeng have not been classified as dangerous buildings, they have been included in the scope of old residential area renovation. During the renovation process, basic improvements such as road surface and sewer upgrades were carried out, and garbage chutes with safety hazards were removed. Although this renovation project did not directly involve prefabricated houses, it reflects the active efforts of the Kaifeng area in improving residents' living environments.
