Wall Thickness of Concrete Prefabricated Houses

The wall thickness of concrete prefabricated houses generally ranges from 120 millimeters to 150 millimeters.

The wall thickness of concrete prefabricated houses typically falls within the range of 120 millimeters to 150 millimeters. In practical applications, some prefabricated concrete houses adopt a factory-standardized production model, where the wall thickness is uniformly controlled at 15 centimeters, or 150 millimeters. This standardized production method helps ensure the quality and dimensional accuracy of housing components, improves construction efficiency, and reduces errors and uncertainties during on-site construction.

From a structural performance perspective, wall thickness within this range can meet certain structural requirements. Thicker walls provide relatively good structural stability, enabling them to bear the weight of the house itself and external loads, such as wind and seismic forces, to a certain extent. At the same time, they also provide space for the installation of internal pipelines within the house.

However, concrete prefabricated panel walls have some obvious drawbacks. Poor thermal insulation is one of the prominent issues. Due to the strong thermal conductivity of concrete materials, thinner walls are unable to effectively block heat transfer, resulting in poor insulation performance in winter, requiring more energy to maintain indoor temperatures; in summer, indoor overheating is prone to occur. Insufficient structural stability is also a significant problem. Compared to traditional brick-concrete structures or reinforced concrete structures, the overall integrity and seismic performance of concrete prefabricated panel walls are relatively weak. When subjected to large external forces, they are prone to cracking, deformation, and even collapse, posing safety hazards. Weak load-bearing capacity also limits their application scope, making it difficult to meet the construction needs of buildings with high load-bearing requirements.

In view of the above issues, concrete prefabricated panel walls have been banned in the construction field and are only still used in certain specific areas, such as temporary buildings or simple sheds. These specific scenarios have relatively low requirements for the long-term performance and safety of buildings, placing more emphasis on rapid and economical construction. Concrete prefabricated houses can meet these needs to a certain extent.
