Xiangtan Container House Design
The design of container houses in Xiangtan focuses on modularity, efficient construction, and flexible application, integrating structural mechanics, climate adaptability, and safety standards to form a scientific and systematic solution.
Structural Design: Mechanical Principles and Safety Assurance
The main body of the container house is made of corrugated plates formed by cold-bending galvanized steel sheets, designed based on the "thin-walled member stability theory" to enhance bending resistance by increasing the section moment of inertia. The load-bearing system consists of a self-balancing frame composed of a bottom frame (H-shaped steel or square tubes welded from high-strength steel), corner columns, and a top frame. The joints follow the principle of "strong joints and weak members" to ensure that the connection areas undergo ductile deformation first during earthquakes or transportation, absorbing energy. The corner columns and top frame are connected with pins or bolts, allowing relative displacement to eliminate the effects of temperature stress or foundation settlement. When combined, adjacent container columns share a foundation base, forming a continuous load transfer path. In hilly areas, concrete strip foundations or prefabricated screw piles can be selected based on soil bearing capacity.
Spatial Layout: Modularity and Functional Adaptation
Standard containers are designed with a 3-meter modulus, supporting horizontal or vertical stacking and arrangement to create spaces of different areas and layouts. Internal partitions can be flexibly adjusted to meet needs for offices, residences, exhibitions, etc. For example, Hunan Yiyu Space Construction Technology Co., Ltd. offers fully customized development, delivering through dual modes of "integral lifting + component assembly" to adapt to scenarios with no terrain or site limitations. The products feature integrated prefabrication of interior finishes, requiring only foundation connections on-site for immediate use.
Climate Adaptability: Thermal Insulation, Waterproofing, and Moisture Resistance
For the subtropical climate in Hunan, the wall panels are filled with rock wool or polyurethane foam (thermal conductivity < 0.045 W/(m·K)) to meet energy efficiency standards. The roof adopts an interlocking lap design, utilizing gravity drainage to channel rainwater. The container base is elevated to prevent moisture erosion, with EPDM rubber sealing strips (compression rebound rate ≥ 85%) inserted into gaps to maintain airtightness.
Safety Standards: Fire Protection and Electrical Safety
The rock wool sandwich panels have a fire resistance limit of 1 hour. Internal electrical wiring is laid in metal conduits and equipped with leakage protection switches, with a grounding resistance value ≤ 4 ohms to ensure fire and electrical safety.
Application Scenarios and Expansion Logic
The design follows a modular expansion logic of "geometric topological invariance," with individual container dimensions based on a 3-meter modulus to optimize transportation space utilization. It is suitable for scenarios such as temporary dormitories on construction sites, scenic area waystations, and emergency shelters, enabling rapid construction, flexible application, and resource recycling.
