Cement Prefabrication in Housing Decoration
The use of cement prefabricated houses in housing decoration has many characteristics, which are introduced from different aspects below:
Production and Performance
Custom-assembled cement prefabricated houses are cast in one piece using high-standard reinforced concrete, resulting in a dense and sturdy overall structure with mature technology and solid material usage. They possess multiple excellent properties, such as earthquake and pressure resistance, enabling them to withstand earthquakes and significant external forces to a certain extent; fire and flame resistance, effectively preventing the spread of fire and ensuring residential safety; thermal insulation and energy efficiency, helping to reduce energy consumption; wind and moisture resistance, adapting to different climatic conditions; and corrosion and weathering resistance, extending the service life of the house.
Construction Advantages
Construction and installation are fast and efficient, with short project durations and quick learning curves. They are not restricted by seasons or weather conditions, allowing for year-round construction. Taking a three-bedroom, one-living-room cement prefabricated house as an example, four workers can assemble a rough house in a few hours with the help of a crane, representing a 7% increase in speed compared to traditional construction methods.
Service Life and Maintenance
The designed service life of the house is over 70 years, making it highly durable. Maintenance is simple, supporting overall relocation, secondary disassembly and reassembly for reuse, which can significantly save on investment costs through recycling.
Scope of Application
They can be used to create various types of buildings, such as office buildings, small hotels, and staff dormitories; and are widely applicable to scenarios such as rural dilapidated house renovations, rural self-built housing, farm supporting housing, temporary office and accommodation housing on construction sites, and temporary supporting housing for engineering projects.
Price Advantages
The overall cost-effectiveness far exceeds that of traditional house construction. A three-bedroom, one-living-room single-story cement prefabricated house with basic decoration starts at 50,000 yuan.
Existing Problems
The sound insulation capability is poor. When there is insufficient prefabricated panel material, sound penetration is strong, and the structure transmits sound. The prefabricated panels are generally about 10 centimeters thick with long circular holes in the middle, acting as natural sound conductors. Leakage problems are inevitable. Since the prefabricated panels are composed of panel units with gaps between them, rainwater can easily seep in and corrode the steel bars, posing a risk of collapse. If the gaps are not properly treated during construction, it can seriously affect the normal life of the homeowners.
