How to Reinforce Container Houses

The reinforcement of container houses should be carried out with targeted measures based on the usage scenarios (warehousing, transportation, long-term outdoor use). The core methods include structural connection reinforcement, wind and earthquake resistance design, proper stacking, and regular inspection and maintenance.

I. Reinforcement in Warehousing Scenarios

1. Site Preparation: The warehousing site should be leveled and hardened, with a concrete thickness of no less than 15 cm to prevent deformation caused by typhoons or rain. Drainage ditches should be set up around the site to prevent water accumulation from affecting the stability of the foundation. Windbreaks (such as windbreak walls or windbreak forests) should be installed around the site, with their height and strength designed according to the local typhoon level to reduce the direct impact of wind on the containers.

2. Stacking and Connection Reinforcement: The stacking height of containers should not exceed 4 layers, and anti-slip pads should be placed between layers to prevent sliding. Containers on the same layer should be horizontally connected with lashing rods or steel wires through corner fittings holes, with at least 2 reinforcements per row. Containers on different layers should be vertically connected with twist locks, and each corner fitting should be installed. Anti-collision posts or sandbags should be set up at the ends of the stack to prevent the end containers from collapsing due to wind impact.

3. Daily Management: Regularly check whether the connecting parts such as twist locks, lashing rods, and steel wires are loose or damaged, and replace them in a timely manner if problems are found. When a typhoon warning is received, stop operations and comprehensively reinforce all containers, and transfer valuable items. Emergency supplies such as flashlights, raincoats, and first-aid medicines should be stored on the site.

   II. Reinforcement in Transportation Scenarios

4. Pre-transportation Inspection: Check the braking, lighting, and tire performance of the transportation vehicle to ensure that the container is not damaged or deformed. Prepare reinforcement equipment such as lashing belts, steel wires, and fasteners according to the route and weather conditions. The goods should be evenly distributed inside the container, and goods with a high center of gravity should be additionally fixed to prevent shifting during transportation.

5. In-transit Reinforcement Measures: Fix the container to the vehicle with lashing belts or steel wires, and select the lashing points as the corner fittings and vehicle fixing devices. Reinforce the goods inside the container with materials such as wooden boards and steel strips to prevent movement and collision. When a typhoon warning is received, park the vehicle in a safe area (such as a parking lot or service area) and increase the number and strength of the lashing belts.

   III. Reinforcement for Long-term Outdoor Use

6. Foundation Reinforcement: Plan the flatness of the foundation in advance and embed drainage pipes to prevent water accumulation. Reinforce the corners of the container with steel frames and pour concrete piers at the bottom to improve overall stability. The wall panels should be made of double-layer steel plates with fireproof rock wool in between to enhance wind resistance.

7. Structural Optimization: Choose fully welded or light steel keel-type container bodies, and avoid using ordinary non-container temporary buildings that use tie rods as diagonal supports. Large-wave containers should be connected between boxes with bolts, and the steel frame should use channel steel or square tubes with increased material dimensions. Slope drainage and sunscreen coating designs can extend the service life.
