Aluminum Structure Diagram of Container House
Currently, there is no publicly available standard aluminum structure diagram for container houses. However, aluminum-profile mobile container houses typically use a 40×40 industrial aluminum profile frame, achieving modular construction through a combination of bolts and connectors.
Core Structure of Aluminum Profile Frame
The main frame of aluminum-profile mobile container houses is primarily composed of 40×40 industrial aluminum profiles, which are characterized by high strength, corrosion resistance, and lightweight properties. The cross-section is designed as a hollow square structure, allowing for the insertion of reinforcing ribs or filler materials to enhance load-bearing capacity. The frame is assembled using bolts and specialized connectors (such as corner brackets and T-shaped connectors) to form stable rectangular structural units. This design eliminates the need for welding, ensuring structural strength while facilitating rapid assembly, disassembly, and transportation.
Modular Combination Method
The aluminum frame adopts a modular design concept, with individual modules typically conforming to standard container dimensions (e.g., 6 meters × 2.4 meters × 2.6 meters). Modules can be horizontally or vertically connected using bolt connectors, allowing for flexible expansion into single-story or multi-story buildings. For example, two standard modules can be combined into a 12-meter-long house using corner connectors or stacked vertically to form a double-story structure. The design of connectors must consider mechanical distribution to ensure that the shear and tensile properties at the joints meet building code requirements.
Key Connection Node Design
- Corner Connection: L-shaped corner brackets are used in conjunction with high-strength bolts, securing the vertical intersection points of aluminum profiles through pre-drilled holes. The thickness of the corner brackets is typically 8-10 millimeters, with bolt specifications of M12 or M16, ensuring that the connection can withstand lateral wind pressure and vertical loads.
- Horizontal Connection: T-shaped or cross-shaped connectors are used to fix parallel aluminum profiles, achieving balanced multi-point force distribution through bolt groups. This design effectively disperses loads, preventing local stress concentration.
- Ground Fixation: The bottom of the frame is connected to the foundation using expansion bolts, with some designs incorporating adjustable feet to accommodate uneven ground and adjust the house's levelness.
Structural Advantages and Application Scenarios
The lightweight nature of the aluminum frame (30%-50% lighter than steel frames) significantly reduces transportation costs, while its corrosion resistance extends the house's service life, making it particularly suitable for coastal or humid environments. The modular design enables rapid assembly of houses at construction sites, disaster areas, or temporary event venues, with aluminum profiles being reusable after disassembly, aligning with green building principles. Currently, this technology is widely applied in scenarios such as temporary offices, medical stations, and field research stations.
