Container Spliced Mobile House

A container-spliced mobile house is a modular building product that is movable and reusable. It uses a steel frame structure and bolt connections, and is constructed by combining standardized container units.

Origin and Development:
The container-spliced mobile house originated from the practice of transforming old containers into temporary housing. On December 13, 2013, Brighton, UK, first adopted it as a solution to the housing crisis. Since 2022, China has promoted the development of prefabricated buildings through the 'Implementation Plan for Carbon Peaking in the Urban and Rural Construction Sector'. Wenan County in Hebei Province has formed an industrial cluster, and its developed 'space capsule' intelligent container houses have been put into use.

Structural Classification:
There are three types based on structure:

1. Traditional Container-Modified Box Houses: Based on the modification of old containers, they have lower costs but limited spatial flexibility.
2. Brand-New Welded Mobile Container Houses: Made from brand-new steel and welded, they have high structural strength and can be customized in design.
3. Demountable Mobile Container Houses: Components can be disassembled and reassembled, facilitating transportation and reuse, and are suitable for scenarios requiring frequent relocation.

Performance Characteristics:

• Wind and Earthquake Resistance: There are significant differences in product performance among different companies. For example, the products of Suzhou Zhongnan Steel Structure Co., Ltd. can withstand wind speeds of up to 12 and seismic intensities of 8 degrees, with a frame deformation rate of only 0.2%; the products of CIMC Modular Building Investment Co., Ltd. can withstand wind speeds of up to 11 and seismic intensities of 7 degrees, with a deformation rate of 0.3%.
• Installation Efficiency: The quick-assembly container from Suzhou Zhongnan Steel Structure Co., Ltd. takes only 2 hours to install a single unit, and a camp of 100 units can be put into use in 7 days; in commercial pop-up store scenarios, a 20㎡ structure can be built in 2 days, which is 3 days faster than competitors.
• Transportation, Storage, and Reusability: Folding design significantly reduces volume. The folded volume of Suzhou Zhongnan's products is 1/5 of the expanded state, allowing 20 units to be loaded per truck, reducing transportation costs by 40%; during storage, they can be stacked up to 8 layers, increasing space utilization by 60%.
• Other Characteristics: The main body is made of steel, providing wind and earthquake resistance as well as corrosion resistance; the air-gap thermal insulation design ensures sound and thermal insulation performance; the appearance is flexible, supporting stacking and modular layout, reducing sea freight costs for a single unit by nearly 40%; the service life exceeds 20 years, with low costs, typically stackable up to 3 layers, and mainly built as double-story structures in daily use.

Application Scenarios:
In China, they are widely used in temporary office spaces, tourist resort homestays, and smart waste stations, with stable demand in the construction site and rail transit sectors. The overseas market is gradually shifting towards permanent buildings, covering areas such as business offices and tourist villas.
