Container House Reinforcement Plan

The container house reinforcement plan requires a comprehensive consideration of structural assessment, reinforcement design, material selection, and construction key points. The specific measures are as follows:

I. Structural Assessment and Inspection

A comprehensive inspection of the remaining bearing capacity of the container house is necessary, covering key parts such as columns, main beams, foundation caps, and foundation bearing capacity. Professional tools (such as thickness gauges and laser distance meters) are used to evaluate the degree of steel corrosion, weld quality, and the stability of connection nodes. Based on the expanded load requirements (such as cargo weight and equipment weight), a reinforcement plan is issued. For example, in the renovation of old factory buildings, if the original steel frame structure is aged or the load-bearing standard is low, directly adding a second or third-floor steel platform can easily lead to settlement, tilting, or even collapse accidents. Scientific assessment is essential to determine the scope of reinforcement.

II. Reinforcement Design Methods

1. Horizontal Reinforcement
   Use lashing rods or steel wires to horizontally connect containers on the same floor. The lashing rods or steel wires need to pass through the "corner fittings holes" of the containers and be locked with shackles. At least two horizontal reinforcements should be set for each row of containers to ensure inter-layer stability.

2. Vertical Reinforcement
   Use twist locks to connect containers between upper and lower floors. Twist locks should be installed at each corner fitting to prevent inter-layer misalignment. For multi-layer stacking scenarios, strictly control the stacking height (generally not exceeding 4 layers) and set anti-slip pads between layers.

3. End Reinforcement
   Set up anti-collision columns or sandbags at the ends of container stacks to prevent stack collapse caused by typhoons or external impacts. For transportation scenarios, use lashing belts or steel wires to fix the connection between the vehicle and the container, selecting corner fittings and vehicle fixing devices as lashing points.

4. Local Reinforcement
   For aged or under-loaded parts (such as columns and main beams), methods such as adding steel columns, thickening main beams, or adding shear braces can be used to enhance structural strength. For example, in the renovation of old factory buildings, by adding support columns or adjusting load distribution, safety expansion can be achieved within a reasonable budget.

III. Materials and Anti-Corrosion Treatment

1. Reinforcement Materials
   Prioritize the use of high-strength packing belts (such as CC105 type), steel wires, or special corner fitting connectors, avoiding the use of perishable materials such as solid wood. For heavy cargo reinforcement, calculate the reinforcement force according to the CTU-CODE rules to ensure that the material bearing capacity meets the standards.

2. Anti-Corrosion Treatment
   In old factory buildings with humid and dusty environments, newly welded steel structures must undergo hot-dip galvanizing or multi-layer anti-corrosion spraying to prevent corrosion from affecting service life. If the inner wall of the container comes into contact with corrosive cargo, add anti-corrosion coatings or isolation materials.

IV. Construction Key Points

1. Segmented Construction
   Carry out reinforcement work in segments without interfering with the normal production of the factory area to reduce production stoppage losses. For example, complete foundation reinforcement first, and then install steel platforms layer by layer.

2. Dynamic Monitoring
   During construction, conduct real-time monitoring of key nodes (such as welds and twist lock connections) to ensure that the reinforcement effect meets design requirements. In transportation scenarios, drivers need to receive typhoon-resistant transportation safety training and master emergency reinforcement measures.

3. Acceptance and Maintenance
   After reinforcement is completed, conduct load-bearing tests and safety acceptance. Regularly inspect the loosening or damage of reinforcement equipment such as twist locks and lashing rods, and promptly replace aged parts.
