Container House Floor Structure
The floor structure of container houses usually adopts a single-layer or multi-layer combination form, based on a steel frame structure, achieving flexible layout through modular design. The specific structural features are as follows:
I. Single-Layer Structure: Basic Modular Layout
Single-layer container houses are mainly formed by horizontally splicing one or multiple containers to create open or enclosed spaces. For example, in the OostKampville project, the first floor of the house is arranged with two 20-foot container compartments spaced apart, forming a central public space with dining and living rooms on either side. This structure connects indoor and outdoor areas through an open deck design. The walls are often replaced with glass windows to enhance natural lighting while retaining the original corrugated plate structure of the containers, balancing industrial style with living comfort. Single-layer structures are suitable for scenarios with low space height requirements, such as temporary offices, wilderness outposts, or low-rise residences. Their advantages include short construction periods, low costs, and the ability to quickly expand functional areas through modular splicing.
II. Multi-Layer Structure: Vertical Space Optimization
Multi-layer container houses maximize space utilization through vertical stacking, commonly seen in residential or commercial buildings. For example, the second-floor design of OostKampville adopts a 'pin' shaped stacking, with only one container placed on the upper level serving as a private bedroom and bathroom. The triangular roof structure reduces the upper floor area but introduces natural light and views through three-sided panoramic glass windows. Multi-layer structures need to focus on solving load-bearing and stability issues:
- Frame Connection Technology: Standard container frames are welded from profiled steel, with the thickness of the main beams and columns and the fullness of the welding process directly affecting stacking safety. For example, the Hubei Container Customization Guide emphasizes that for multi-layer buildings, it is necessary to confirm whether the manufacturer has multi-layer frame connection technology to avoid risks caused by false welding or steel corrosion.
- Waterproof Node Treatment: Special waterproof designs (such as rubber seals and metal baffles) are required at stacking points to prevent rainwater infiltration and ensure structural durability.
III. Structural Materials and Performance Enhancement
The floor structure of container houses relies on the compressive and wind-resistant capabilities of the steel frame structure, while enhancing living performance through additional materials:
- Wall Materials: Color-steel sandwich panels filled with insulation materials (such as polyurethane and rock wool) balance lightweight and thermal insulation needs, adapting to tropical or cold climates.
- Corrosion Protection: Overall galvanizing or spraying with anti-corrosion coatings can extend the service life to more than 15 years, avoiding structural weakening caused by rust.
- Roof Design: For example, the A-frame roof structure uses a combination of metal panels, translucent materials, and steel louvered vents to block strong light and rain while maintaining air circulation through lower vents to prevent heat buildup.
IV. Modular and Adaptive Design
The floor structure of container houses supports flexible combinations and can adjust functional partitions according to needs. For example, the Yongzhu Packing Container House uses individual containers as units, forming conference rooms, dormitory buildings, and even three-story commercial blocks through stacking or splicing, with adjustable bases to adapt to different terrains. This design not only reduces requirements for ground foundations (such as no need for concrete pouring) but also shortens delivery cycles through standardized production, meeting the rapid deployment needs of emergency housing or creative studios.
