Prefabricated Container Modular House Design

Currently, there are no directly provided detailed design drawings for prefabricated container modular houses, but the design key points and assembly methods can be summarized based on actual cases and product characteristics.

Modular Design Features

Prefabricated container houses adopt standardized modular design, using 20-foot or 40-foot containers as basic units. The main structure, interior decoration, and electromechanical pipeline embedment are completed through factory prefabrication. For example, in the North American project of China Construction Steel Structure, the building was disassembled into four independent modules, each containing complete functional spaces (such as bedrooms, kitchens, and bathrooms). The modules are spliced together through bolts or welding, and on-site, only module positioning, connection, and water and electricity connection are required.

Assembly Process and Efficiency

1. Factory Prefabrication Stage

• Main Structure: Light steel structures or container frames are used to complete the assembly of walls, floors, and roofs.
• Interior Decoration: Integrated wall, floor, and ceiling finishes are installed, along with pre-installed doors, windows, bathroom fixtures, and cabinets.
• Electromechanical Systems: Wires and water pipes are embedded, and interface positions are reserved. Some products are equipped with solar panels or split-type air conditioners.

2. On-site Assembly Stage

• Foundation Treatment: The ground is leveled, and a concrete or steel structure foundation is laid to ensure horizontal positioning of the modules.
• Module Hoisting: A crane is used to hoist the modules to the designated positions, with guiding devices assisting in precise docking.
• Connection and Fixing: High-strength bolts or welding are used to connect the module frames, and seams are treated with sealant.
• Water and Electricity Connection: The embedded pipelines are connected, and the electrical circuits and water supply and drainage systems are tested for normal operation.

Case Data: The Suzhou Zhongnan team completed the delivery of 1,000 accommodation modules within three months through the "factory prefabrication + on-site rapid assembly" model in the Qatar World Cup project. The installation time for a single module was only 2 hours, shortening the construction period by 40% compared to traditional buildings.

Structural Safety and Materials

• Main Materials: Q235 or Q355 steel is mostly used, with a wind resistance rating of up to Level 12 and a seismic fortification intensity of Level 8.
• Thermal Insulation: The walls are filled with rock wool or polyurethane foam, with a thickness of 50-100mm, combined with double-glazed windows to meet the usage requirements in cold or hot regions.
• Fire Resistance: Class A fire-resistant rock wool boards are used, with a fire resistance limit of 1-2 hours, meeting international fire protection standards.

Applicable Scenarios and Expandability

• Temporary Buildings: Construction site dormitories, emergency medical stations, and post-disaster reconstruction housing can be quickly assembled and disassembled for repeated use.
• Permanent Residences: By increasing the number of modules or stacking layers (usually not exceeding 3 floors), they can be expanded into villas, hotels, or schools.
• Customized Design: Support for exterior painting and interior layout adjustments, with some products reserving interfaces for smart home systems.
