Reinforcement of Container Mobile Houses

The reinforcement of container mobile houses requires comprehensive treatment from multiple aspects such as structure, connections, materials, and wind and earthquake resistance design.

1. Structural Reinforcement
Container mobile houses are framed with steel structures. Reinforcement requires ensuring that the steel thickness meets standards (usually 1.6mm-2.0mm) and prioritizing the use of high-strength cold-rolled steel plates or galvanized steel beams and columns. For example, columns can be welded using 2.3mm-2.5mm galvanized materials, and the chassis can be reinforced with thickened channel steel and galvanized square tubes to enhance overall load-bearing capacity. For second-hand containers, secondary rust prevention treatment is necessary, such as sandblasting to remove rust followed by the application of special paint to prevent rust from weakening structural strength.

2. Connection Node Strengthening
Adopting a triangular load-bearing system and bolted connections at nodes can significantly improve wind and earthquake resistance. For example, reinforcing the corners of the container with steel frames and fixing the chassis to the main body with bolts can avoid stress concentration caused by welding. For foldable designs (such as three-opening containers), large hinges should be used to connect the main body and side containers, and the wear of the hinges should be regularly inspected to ensure the stability of the folding mechanism.

3. Wind and Earthquake Resistance Design
Container houses used outdoors for long periods need to meet the standard of withstanding winds of up to force 12. Reinforcement measures include:

• Pouring concrete piers at the bottom to increase the contact area with the ground;
• Reserving drainage slopes to prevent water accumulation from causing foundation settlement;
• Installing anti-corrosion wooden exterior walls or reflective coatings to reduce wind resistance and enhance durability.
  In addition, structural calculations should comply with the 'Code for Design of Steel Structures' to ensure that the load-bearing capacity meets standards.

4. Material Upgrades
Walls should be filled with high-density insulation materials (such as rock wool or polyurethane), combined with moisture-proof and ventilation layers to form a multi-layer protective system that not only improves thermal insulation performance but also prevents condensation water from corroding the steel frame. For temporary buildings, A-grade fire-resistant rock wool can be used to fill the walls, balancing safety and environmental protection.

5. Modular Combination Optimization
When achieving rapid hoisting and reuse through standardized interfaces, it is necessary to ensure the sealing of container joints. For example, using structural adhesive to seal the joints between glass curtain walls and steel frames can prevent rainwater infiltration. At the same time, avoid simply stacking containers but disperse stress through reasonable layouts (such as staggered splicing) to enhance overall stability.
