Container House Structural Reinforcement

Container house structural reinforcement can be achieved through various technical means. It is necessary to select appropriate solutions based on specific scenarios and pay attention to the collaborative guarantee of materials and construction techniques.

I. Foundation Reinforcement Techniques

1. Raft Foundation and Embedded Part Welding
The patented technology of Dongguan Yashun Light Steel Structure Co., Ltd. significantly enhances the connection stability between the container body and the ground through the combination of a raft foundation (concrete structure) and embedded parts. The upper end of the embedded parts is equipped with a welding surface, and the support column feet (spaced and arranged at the lower end of the container body) are directly welded to the welding surface, forming a rigid connection. This technology can effectively resist wind loads and seismic actions, making it suitable for container houses used outdoors for long periods, especially in scenarios with high wind and earthquake resistance requirements, such as construction site dormitories and temporary office spaces.

2. Concrete Pier Reinforcement
For container houses with insufficient bottom stability, concrete piers can be added at the bottom to disperse the load by expanding the foundation contact area and reduce the risk of foundation settlement. This method is often combined with the technique of reinforcing the corners with steel frames to form a dual protection system of "bottom stability + corner strengthening".

II. Structural Main Body Reinforcement Techniques

1. Cantilever Reinforcement Structure
For the cantilevered parts of container houses, such as balconies and extended corridors, a combination of rolled-edge U-shaped reinforcement members, end plates, and self-tapping screws can be used. The end plates are fixed to the lower container corner fittings, and the rolled-edge U-shaped reinforcement members are connected to the upper container bottom beams with self-tapping screws, achieving non-welding reinforcement. This technology maintains the convenience of modular installation of container houses while enhancing the anti-deformation ability of the cantilevered structures.

2. Steel Frame and Profile Steel Wrapping Reinforcement
For container houses with insufficient overall structural rigidity, steel frames (such as portal frames and cross-bracing) can be added at key locations, or the method of wrapping profile steel around existing members can be used. The latter enhances the load-bearing capacity and stability of the members by wrapping profile steel around their outer surfaces, making it suitable for multi-story stacking or high-load scenarios.

III. Material and Construction Guarantee

1. High-Performance Reinforcement Materials
Selecting building reinforcement materials that meet standards (such as Hilti HIT-RE 500 V3 epoxy resin anchor adhesive and carbon fiber cloth adhesive) can significantly improve the reinforcement effect. The materials need to have corrosion resistance and anti-aging properties to adapt to harsh outdoor environments.

2. Construction Technique Specifications
Reinforcement construction must strictly follow design specifications. For example:

• The positioning accuracy of embedded parts must be controlled within ±2mm;
• Welding operations must meet the requirements of the "Code for Welding of Steel Structures" (GB50661);
• Self-tapping screw connections must ensure that the torque values comply with design parameters.
  In addition, the construction process should be made traceable through information technology means (such as uploading images of risk nodes) to avoid human operational errors.
