Chongqing Container House Specifications Diagram
The common specifications of container houses in Chongqing are mainly 3 meters × 6 meters, with some customized products reaching 6 meters × 9 meters or larger. International standard containers come in two main sizes: 20 feet (approximately 6.1 meters × 2.4 meters × 2.6 meters) and 40 feet (approximately 12.2 meters × 2.4 meters × 2.6 meters).
I. Common Specifications and Sizes
Container houses in the Chongqing market predominantly feature a standardized size of 3 meters × 6 meters. These products often utilize color-coated steel plates or steel structural frames, making them suitable for construction site dormitories, temporary warehouses, and other scenarios. For example, the residential container houses provided by Chongqing Yaju Container Co., Ltd. are of the 3-meter × 6-meter specification, with an area of approximately 18 square meters, meeting basic living needs.
Some projects adopt customized containers of 6 meters × 9 meters or larger sizes, achieving spatial expansion through modular assembly. For instance, the Chongqing municipal project 'Minxing Jiayuan Youth Environmental Experience Center' was assembled on-site using 6-meter to 9-meter containers, with a total construction period of only one month. The Aegean Sea Container Commercial District in Yubei District forms a distinctive commercial space by combining multiple 6-meter containers.
Regarding international standard containers, the internal dimensions of a 20-foot container are approximately 6.1 meters (length) × 2.4 meters (width) × 2.6 meters (height), with a load-bearing capacity of up to 25 tons. The internal dimensions of a 40-foot container are approximately 12.2 meters (length) × 2.4 meters (width) × 2.6 meters (height), with a load-bearing capacity of 45 tons. These containers are primarily used for maritime transport or large-scale temporary buildings, such as the Beijing Metro Line 8 Qianmen project and the Xinjiang Dashixia Dam project.
II. Structural and Load-Bearing Characteristics
The load-bearing capacity of container houses depends on the material and structural design. Standardized containers are made of high-strength steel, with a 20-foot container capable of bearing 25 tons of cargo and a 40-foot container capable of bearing 45 tons. After being transformed into buildings, they still retain some load-bearing capacity.
Customized container houses enhance stability through structural optimization. For example, Chongqing Jiayu Smart Construction Technology adopts double-layer steel structures or formed steel welding, combined with mechanical design to enhance stability. The container houses produced by Xi'an Jimei feature galvanized steel frames, offering excellent wind and earthquake resistance, with a service life of over 20 years.
III. Application Scenarios and Expandability
The specification design of container houses is flexible and can be adapted to different needs through assembly and combination. Small single-container buildings are suitable for construction site dormitories, guard posts, and other scenarios. Large combined buildings are used for complex functional spaces such as commercial streets and office buildings. For example, a procurement project by a state-owned enterprise in Chongqing combined 40 6-meter and 9-meter containers into a comprehensive office building, including a canteen, conference room, dormitory, and other functional areas.
