Movable Prefabricated Concrete House

A movable prefabricated concrete house is a new type of building form that produces building components through industrialization and assembles them on-site, featuring earthquake resistance, wind resistance, fast construction, and customization.

1. Structure and Earthquake/Wind Resistance Performance Movable prefabricated concrete houses adopt light steel composite panel houses or prefabricated assembled structures. By reasonably combining materials and steel structures, they can withstand earthquakes of magnitude 7 or above and typhoons of level 12. For example, the Baoding new-type cement integral house has a special-grade snow load and wind resistance rating. Its reinforced concrete structure makes each unit weigh over 20 tons, ensuring strong overall stability. The core components (beams, slabs, walls, and columns) are industrially produced using specialized equipment, ensuring structural accuracy and strength. After on-site assembly, they form an integrated load-bearing system, significantly enhancing disaster resistance.

2. Types and Construction Characteristics The main types include panel-assembled, box-assembled, and frame-assembled structures.

• Panel-assembled: Primarily using prefabricated wall panels, floor slabs, and other components, it offers flexible construction and is suitable for multi-story buildings.
• Box-assembled: By combining prefabricated functional units (such as room modules), construction speed can be increased by 50%-70%. However, it has high requirements for transportation and lifting equipment and is suitable for standardized and large-scale projects.
• Frame-assembled: With a prefabricated frame structure as the core, it offers flexible spatial layouts and is commonly used in high-rise or complex buildings. In terms of construction speed, the prefabricated cement movable house in Luoyang can be completed within one day, significantly shortening the construction period and reducing on-site wet operations and labor dependence.

3. Customization and Cost-effectiveness Some brands (such as Zhongjiang Lvjian and Xinwei Hongtu) offer customization services, allowing specifications, sizes, and uses (temporary residences, construction site offices, rural villas, etc.) to be adjusted according to demand. Taking the Baoding new-type cement integral house as an example, the price starts at 260.00 yuan per square meter, with a minimum order quantity of 1,000 square meters. It has a service life of over 70 years, demonstrating significant long-term cost advantages. Its nationwide availability also expands its application scope.

4. Application Scenarios and Limitations It is suitable for scenarios with high requirements for construction speed and disaster resistance, such as post-disaster reconstruction, temporary buildings, and rural low-rise residences. However, the box-assembled type has high requirements for transportation roads and lifting equipment due to the large volume of modules, necessitating advance planning of logistics routes. The frame-assembled type requires precise design of node connections and strict adherence to technical specifications.
