Container House Foundation Drawing
The foundation drawing of a container house typically needs to be designed in combination with the container specifications, assembly method, and foundation type. Common forms include pile foundations or strip foundations, which require early construction and consideration of moisture-proofing and insulation needs.
1. Foundation Type Selection
The foundation of a container house should be determined based on geological conditions, container specifications, and assembly methods. Pile foundations are a common choice, effectively preventing moisture and providing insulation by elevating the container above the ground on piles, especially suitable for humid or rainy regions. For example, in one case, a pile foundation was used to support two assembled containers, creating a layout that included a living room, dining room, kitchen, and bedroom. Strip foundations or raft foundations can also be used in stable geological conditions, ensuring that the foundation width and depth meet the load-bearing requirements of the containers (25 tons for a 20-foot container and 45 tons for a 40-foot container).
2. Container Assembly and Layout
The foundation design should match the container assembly method. Horizontal assembly can expand indoor space, such as assembling two 20-foot containers to create a layout with a 12-meter width and 4.9-meter depth, suitable for dividing into a living room and bedroom. Vertical stacking requires consideration of structural stability, necessitating reinforcement with steel beams or welding at connection points. When assembling, openings for doors and windows should be reserved, and the seal between containers should be ensured to prevent rainwater leakage. For example, a rural container house increased its space by connecting two containers and installing wooden frame partitions.
3. Moisture-Proofing and Insulation Measures
Moisture-proofing and insulation should be considered simultaneously during foundation construction. Pile foundations prevent ground moisture from entering by elevating the container, while insulation layers (such as polystyrene boards) can be laid at the bottom of the container or a real fireplace installed to enhance warmth. Waterproofing requires the installation of drainage ditches around the foundation and the application of waterproof coatings at container joints. For example, in one case, wooden frames were installed inside the container and filled with insulation material, and double-glazed windows were used to improve energy efficiency.
4. Construction Process and Precautions
Foundation construction should be completed in advance, including excavation, pile foundation pouring, or strip foundation masonry. Before lifting the container, the foundation flatness should be checked, with an error tolerance of ±5mm. High-strength bolts should be used to fix the container connection points during assembly, and key nodes should be reinforced by welding. Interior decoration should be carried out after the container is stabilized, including the laying of water and electricity lines, installation of partitions, and floor treatment. For example, in one project, doors, windows, lights, and a real fireplace were installed after container assembly, completing the decoration.
