Lifting Prefabricated Concrete House

A lifting prefabricated concrete house is a prefabricated building form that can be moved as a whole by a crane without disassembly. Its main body is composed of concrete modules, featuring a short construction period and superior structural performance.

Production and Installation Process

The lifting prefabricated concrete house adopts a factory-prefabricated production model. Concrete components are poured and cured in standardized workshops and then transported to the construction site for overall assembly through splicing and installation. Its core processes include:

1. Modular Design: The main body of the building is composed of multiple concrete modules. Each module can integrate electromechanical pipelines, decorative components, etc., reducing on-site construction links. For example, in some renovation projects, modular assembly is achieved through automobile lifting, with each module directly containing a complete functional system.
2. Connection Technology: The modules are connected using on-site steel bar splicing and concrete pouring processes to ensure the overall structural stability. This connection method can effectively transfer loads and avoid strength losses caused by splicing gaps.
3. Material Selection: The manufacturer may use commercial concrete materials from circular economy clusters, ensuring both concrete quality and environmental protection requirements.

Structural Performance Advantages

1. Standardized Production Ensures Quality: Factory-prefabricated production makes the dimensional accuracy and strength uniformity of concrete components significantly better than on-site pouring, resulting in more stable structural performance.
2. High Load-Bearing Capacity: Some products can withstand snow loads ranging from 100 kg/m² to 1000 kg/m², making them suitable for alpine or snowy regions.
3. Multi-Functionality: They possess earthquake resistance, fire resistance, and energy-saving properties. The high density of concrete gives it a natural fire-resistant advantage, while modular design can enhance overall earthquake resistance by adding earthquake-resistant components.

Application Scenarios

1. Temporary or Small Buildings: Such as guardhouses and kiosks, their rapid installation characteristics can meet temporary usage needs.
2. Rural Revitalization Projects: In 2023, Huoshaocheng Village, Shimen Town, Tianzhu County, adopted lifting houses as affordable housing, proving their suitability for permanent residential scenarios.
3. Renovation and Expansion: Through modular assembly, building functional upgrades or space expansions can be quickly achieved, especially suitable for projects with strict construction period requirements.

Limitations

Although lifting prefabricated concrete houses have significant advantages, their application is still restricted by transportation conditions. Large concrete modules require special vehicles for transportation, imposing high requirements on road width and load-bearing capacity, which may increase construction costs in remote areas or complex terrains.
