Fixing of Container Mobile Houses

The fixing of container mobile houses can be achieved through foundation treatment, connection reinforcement, wind and earthquake resistance design, and standardized installation operations. The specific methods are as follows:

Foundation Treatment and Base Fixing

The stability of container mobile houses primarily depends on the leveling and reinforcement of the foundation. Before construction, the site should be leveled, debris removed, and the soil compacted to prevent house tilting due to foundation settlement. For long-term use scenarios, it is recommended to pour a concrete foundation or lay steel ground beams, and fix the corner fittings at the bottom of the container to the foundation using bolts to form a stable support structure. For example, for container houses used outdoors for a long time, concrete piers can be set at the bottom to disperse pressure and enhance wind resistance.

Connection Reinforcement and Structural Stability

The fixing of containers should focus on corner fitting connections and frame reinforcement. Standard containers are stacked and fixed through corner fittings. High-strength bolts or welding can be used to tightly connect the corner fittings of adjacent containers to form an integral structure. For houses stacked in multiple layers or spliced horizontally, steel support frames or beams should be added at the connections to enhance structural rigidity. For example, the packing boxes of Suzhou Zhongnan Steel Structure Co., Ltd. adopt a full steel structure frame, ensuring weld strength through automatic welding processes. The measured wind resistance rating reaches Level 12, the earthquake resistance rating reaches Level 8, and the frame deformation rate is only 0.18%, far below the industry's qualified threshold.

Wind and Earthquake Resistance Design

In areas prone to extreme weather, the wind and earthquake resistance design of container houses is crucial. Safety can be enhanced through the following measures:

• Steel Frame Reinforcement: Add steel diagonal braces or beams at stress concentration areas such as house corners and door and window openings to disperse wind loads and seismic forces.
• Anchoring System: Use ground anchor bolts or steel cables to fix the house to the ground to prevent it from being overturned by strong winds. For example, the standard container houses of CIMC Modular Building Investment Co., Ltd. incorporate a semi-welded and semi-bolted connection structure in their frame design. Although the bolts may loosen after long-term use, stability can be maintained through regular inspections and tightening.
• Bottom Ballast: Fill the bottom of the house with concrete or heavy objects to lower the center of gravity and enhance anti-overturning capability.

Standardized Installation and Regular Maintenance

During installation, strict adherence to operational specifications is required to ensure accurate lifting points and properly tightened connections. After installation, the house structure should be regularly inspected, with a focus on key parts such as welds, bolts, and corner fittings, and aging or damaged components should be replaced in a timely manner. For example, under standardized use and regular maintenance conditions, compliant products can be disassembled and reused an average of more than 8 times, reducing construction waste emissions by about 90% and significantly improving resource utilization.
