Concrete Prefabricated House Construction

Concrete prefabricated house construction is a modern building method that is efficient, environmentally friendly, and quality-controllable, with its core being the combination of factory prefabrication and on-site assembly, suitable for various scenarios.

I. Construction Process

The construction of concrete prefabricated houses is divided into two main stages: factory prefabrication and on-site hoisting.
Factory Prefabrication: On standardized production lines, processes such as steel bar tying, mold assembly, and concrete pouring are fully mechanized. The production cycle for a single module is only 7 days, with an error margin controlled within 2 millimeters. This industrial production model ensures the precision and quality stability of the components.
On-site Hoisting: After the prefabricated components are transported to the construction site, they are assembled using cranes in conjunction with intelligent positioning systems. For example, the main structure of a single villa can be installed in just 4 hours, and a 100㎡ house can be ready for occupancy in just 5 days from an empty lot, significantly shortening the construction period.

II. Technical Characteristics

1. Structural Stability: A full-frame shear wall structure is adopted, using C35 concrete and Φ14 threaded steel bars. The reinforcement ratio of a single module reaches 1.2%, with a wall thickness of 200mm and a compressive strength of 30MPa, ensuring the seismic and load-bearing performance of the house.
2. Connection Method: Modules are connected using pre-stressed bolts (with a tensile strength of 25 tons) combined with the mortise-and-tenon joints of ancient-style buildings, ensuring overall stability while enhancing wind and earthquake resistance.
3. Smart Integration: EPS insulation layers are embedded in the walls, and photovoltaic panel interfaces are reserved on the roof, improving the energy-saving and environmental performance of the house, in line with green building standards.

III. Construction Advantages

1. Short Construction Period: Compared to traditional house building, the construction efficiency of prefabricated concrete houses is significantly improved. For example, the construction period for a 300㎡ house is shortened from 6 months to just 1 day, greatly reducing time costs.
2. Low Cost: Labor costs are reduced by 60%, and construction waste is reduced by 98%, significantly lowering the overall house-building cost while also reducing noise and dust pollution from on-site construction.
3. Quality Controllable: Factory production ensures the stability of component quality, and on-site assembly is quick and convenient, greatly shortening the design and construction cycle compared to traditional buildings.

IV. Scope of Application and Precautions

Concrete prefabricated houses are suitable for various scenarios such as family residences, schools, office buildings, hotels, and factory dormitories, and can be built as multi-story or high-rise buildings. Note: Early concrete prefabricated panel houses had issues such as poor sound insulation and water leakage, but modern technology has significantly improved performance through improved materials and connection methods. It is recommended to choose professional manufacturers for construction to ensure material quality and construction specifications, avoiding safety hazards caused by non-professional operations.
