Images of Container Finished Houses
Currently, images of container finished houses cannot be directly provided, but their typical features and design points can be described in text:
Structural Types and Prefabrication Features
Container finished houses are based on standardized shipping containers, with common sizes being 20 feet (length: 6.058 meters, width: 2.438 meters, height: 2.591 meters) and 40 feet (length: 12.192 meters, width: 2.438 meters, height: 2.591 meters). They are highly prefabricated in factories, with the main structure using high-strength galvanized steel frames. The walls integrate rock wool sandwich panels (thickness: 80 - 100 millimeters), and the roof and floor are connected by welding or bolts to form rigid units. For example, the products of Baotou Xinxing Color Plate Steel Structure Manufacturing Co., Ltd. have pipeline embedment, interior and exterior wall decoration, and door and window installation completed in the factory. The on-site installation error can be controlled within millimeters, significantly improving the squareness of the space.
Thermal Performance Optimization Design
To address the high thermal conductivity of metal containers, a three-layer structure is adopted to enhance thermal insulation: The outer layer is a 0.6-millimeter-thick galvanized steel plate to resist wind and sand erosion. The middle layer is filled with rock wool as the main insulation layer, and the inner layer uses PVC-coated steel plates to reduce thermal radiation. Some designs add a 50 - 100 millimeter elevated layer at the bottom of the container to block the conduction of ground cold bridges. For example, a product from a company in Hohhot reduces indoor temperature fluctuations by 40% compared to traditional color steel plate houses through this structure, but it requires the use of sealing strips to treat the joints of doors and windows; otherwise, condensation is likely to occur.
Space Functional Zoning Strategies
The fixed container size (e.g., 3 meters × 6 meters) necessitates the use of functional overlapping design: The kitchen and bathroom are compressed to one end of the container to form a wet area, using integrated bathroom technology for waterproof integration. The living and sleeping areas achieve day-night functional switching through convertible furniture. For example, in a case in Jiangsu, a wall-mounted folding table (which can be retracted into the wall during non-meal times) and a drop-down bed (which releases a 2.5-meter × 4-meter activity space when retracted) are used. However, it requires residents to systematically plan storage; otherwise, the actual usable area may shrink by more than 20%.
Modular Combination and Expandability
Multiple containers can be combined through bolt connections or welding to expand into two-story or complex spatial forms. For example, a project in Denmark uses 9 containers to stack a family house with large windows, and an eco-hotel in South Africa forms a two-story structure with 6 containers, naturally creating a courtyard in the middle. When combining, attention should be paid to structural load balance. Welded containers have strong anti-deformation capabilities and are suitable for frequent lifting; bolt-connected containers require regular inspection of the tightness of connection nodes.
