Container Double-Wing Expansion House

The container double-wing expansion house is a modular box-type house with expandable space. It increases the usable area by unfolding the wings on both sides, combining transportation economy with space utilization efficiency. It is suitable for temporary office spaces on construction sites, overseas camps, emergency rescue, and other scenarios.

Core Functions and Design Features

1. Space Expandability
   The double-wing expansion house is in standard container size during transportation. After being unfolded using hydraulic or mechanical structures, the usable area can increase by 2-3 times. For example, a 20-foot container, when unfolded, has an indoor area of approximately 36 square meters. It can be flexibly planned as a residence (two bedrooms, one living room, one kitchen, and one bathroom) or a storage space, meeting diverse needs.

2. Rapid Deployment and Retrieval
   Full-house integrated pre-assembly (structure, insulation layer, water and electricity pipelines, etc.) is completed before leaving the factory. On-site, it only takes about 1 hour to hoist, unfold, and connect to water and electricity for immediate use. The construction process involves no wet operations and generates no construction waste. It supports multiple turnovers and repeated use, significantly reducing time and labor costs.

3. Environmental Adaptability and Safety
   It adopts a high-strength light steel frame and anti-corrosion treatment process, featuring fire resistance, heat preservation, heat insulation, waterproofing, wind resistance (up to Level 9), and earthquake resistance. It can adapt to extreme environments such as deserts, extremely cold regions, and high-temperature areas. For example, projects in the Middle East require wind and sand resistance and high-temperature resistance, while projects in Russia optimize insulation design.

Technical Advantages and Cost-Effectiveness

1. Transportation Cost Optimization
   In the folded state, its volume is only one-fourth of that in the unfolded state. A single 40-foot sea container can load 15-20 sets (while traditional fixed containers can only load 2-3 sets). Sea freight costs are reduced by more than 60%, making it especially suitable for long-distance overseas projects in the Middle East and Africa.

2. Modularity and Customization
   It supports horizontal splicing or vertical stacking of multiple containers, allowing free combination into functional spaces such as office areas, dormitory areas, and comprehensive camps. Dimensions, interiors, and functional configurations (such as intelligent systems) can all be customized to meet different domestic and international standards (such as CE and ASTM).

3. Green Sustainability
   Factory prefabrication combined with on-site dry construction methods and recyclable materials meet green building requirements. Its lightweight design reduces resource consumption and provides a low-cost solution to housing shortages.

Typical Application Scenarios

• Overseas Infrastructure Camps: Quickly build office and dormitory areas, such as oil camp projects in the Middle East.
• Emergency Rescue: Rapidly deploy medical or shelter facilities after disasters, relying on its wind and earthquake resistance.
• Cultural Tourism and Commerce: Serve as guesthouses, popular photo spots, or commercial block modules, supporting flexible relocation and reorganization.
