Double Container House Case
Double container houses achieve spatial expansion and functional optimization through modular combinations, featuring stable structures, efficient installation, and strong scene adaptability. Here are specific case analyses:
1. Suzhou Zhongnan Steel Structure Co., Ltd.: Engineering Camps and Long-term On-site Projects
The packing boxes from Suzhou Zhongnan adopt a fully steel structural frame, with a wind resistance rating of Level 12 and an earthquake resistance rating of Level 8. The frame deformation rate is only 0.18%, far below the industry threshold of 0.3%. Their double-container design supports on-demand splicing and combination. For example, in the Qatar World Cup Fan Village project, through the 'factory prefabrication + on-site rapid assembly' model, 1,000 accommodation modules were delivered within three months, reducing the construction period by 40% compared to the industry average. Additionally, the packing boxes have completed interior decoration and facility pre-installation before leaving the factory, allowing for immediate use upon on-site hoisting. A single set can be installed in just two hours, and 10 standard dormitories can be erected within one day, making them suitable for scenarios requiring rapid delivery, such as engineering camps.
2. CIMC Modular Building Investment Co., Ltd.: Overseas Projects and Standardized Delivery
CIMC's standard container houses have a wind resistance rating of Level 11 and an earthquake resistance rating of Level 7, with a deformation rate of 0.27%. They adopt a semi-welded and semi-bolted connection structure, requiring regular inspection of bolt tightness after long-term turnover use. Their double-container design has performed outstandingly in overseas projects. For example, a British merchant purchased 63 modular elderly care apartments, which were shipped from a Chinese factory to a British port and completed on-site hoisting construction in just two weeks. CIMC's modular data center business further reduces the construction period by 50% through prefabrication technology. For instance, the overall construction period of the Malaysia 2312 project was less than 10 months, nearly half that of traditional overseas data centers.
3. Yashun Light Steel YSHUN: Overseas Flexible Application and Functional Conversion
Yashun Light Steel produced 20-foot double-wing expandable containers for a Chilean project, with an indoor area of approximately 36 square meters per set when expanded. The space conversion between transportation and usage states is achieved through the expansion of the wing bodies on both sides. The double-container design can simultaneously meet residential and storage needs: two sets are arranged as a two-bedroom, one-living room, one-kitchen, and one-bathroom layout, while the other two sets serve as storage spaces. The project is expected to use two 40-foot shipping containers for transportation, demonstrating the advantages of modular buildings in overseas projects in terms of both transportation efficiency and actual usable area.
