Hoisting-type Prefabricated House

A hoisting-type prefabricated house is a prefabricated building that can be hoisted and moved as a whole by a crane without disassembly. Its main body is composed of metal decorative insulation panels or concrete modules, suitable for scenarios such as guard posts and kiosks.

Constituent Materials and Functional Characteristics The panels of hoisting-type prefabricated houses are made by compounding carved aluminum-zinc alloy steel plates with polyurethane insulation layers. The surface can present decorative effects such as marble and cultured stone, combining aesthetics with insulation performance. Concrete modules are prefabricated in factories and then hoisted on-site, possessing functions such as earthquake resistance, fire resistance, and energy conservation. Its core design concept is to disassemble the building into independent modules, complete the assembly-line prefabrication of all components including ceilings, floors, and water and electricity pipelines in the factory, and then transport them to the construction site for assembly. For example, the connection between modules adopts the on-site steel bar splicing and concrete pouring process to ensure structural stability.

Comparative Advantages over Traditional Construction Techniques

1. Short Construction Period: In a public housing project in Shenzhen, Guangdong, 6028 concrete modules were assembled, reducing the completion and delivery time from 2.5 - 3 years to 1 year, and the on-site labor force was reduced by about 50%.
2. Controllable Quality: The factory prefabrication model eliminates quality fluctuations in traditional construction. For example, the integrated production of mechanical and electrical pipelines and decorative components can avoid on-site installation errors.
3. Energy Conservation and Environmental Protection: Modular construction significantly reduces on-site noise, dust, construction waste, and traffic congestion. Taking the Shenzhen project as an example, the interference with the surrounding environment during its construction was significantly reduced.
4. Easy Maintenance: The standardized design of prefabricated components facilitates later maintenance and replacement. For example, metal decorative insulation panels can be individually removed and repaired.

Application Scenarios and Industrial Requirements Hoisting-type prefabricated houses have been applied in small buildings such as guard posts and kiosks, as well as in rural revitalization housing projects (such as the 2023 project in Huoshaocheng Village, Shimen Town, Tianzhu County). However, its promotion depends on a complete industrial foundation, requiring the coordinated support of technical systems, production systems, and industrial clusters. For example, the transportation radius of concrete modules, the matching of hoisting equipment, and the standardization of on-site assembly processes all require systematic solutions.

Typical Cases A renovation project adopted concrete modular construction technology, planning multiple prefabricated modules. Each module integrated mechanical and electrical pipelines and decorative components, and was quickly assembled through truck hoisting. Such practices have verified the adaptability of hoisting-type prefabricated houses in complex scenarios and provided technical references for large-scale applications.
