How to Reinforce Container Houses
Reinforcing container houses requires comprehensive handling from aspects such as foundation connection, structural reinforcement, stacking specifications, and transportation fixation. The specific methods are as follows:
I. Foundation and Ground Connection Reinforcement
The firmness of the connection between a container house and the ground directly affects its overall stability. The raft foundation + embedded part welding technique can be employed: First, pour a concrete raft foundation, embed metal parts with welding surfaces inside the foundation, and then weld the supporting column feet at the bottom of the container to the embedded parts. This method can significantly enhance seismic performance and reduce the impact of typhoons or earthquakes on the house. If site conditions are limited, expansion bolts or chemical anchors can also be used to fix the container corner fittings to the ground, but it is essential to ensure that the bolt specifications match the weight of the container.
II. Structural Overhang and Wall Reinforcement
For the overhanging parts of containers or weak sections of walls, the flanged U-shaped reinforcement + self-tapping screw technique can be adopted: Install U-shaped reinforcement pieces at the connection points between the container bottom beam and corner fittings, and fix them with self-tapping screws to form triangular support structures, enhancing the anti-deformation capability of the overhanging parts. For multi-story container houses, horizontal connecting rods need to be added between floors. Use steel wire ropes or strapping bands to pass through the corner fitting holes and tighten them to prevent inter-floor misalignment. Additionally, additional steel plates can be welded at the container joints to improve overall rigidity.
III. Stacking and Windproof Reinforcement
The storage site should be hardened in advance to ensure a flat ground with good drainage. When stacking containers, the height should not exceed 4 layers, and anti-slip mats should be laid between layers to prevent sliding. Containers in the same row should be horizontally connected with strapping rods or steel wire ropes, with at least 2 reinforcements set for each row; twist locks should be used between upper and lower layers of containers to ensure installation at each corner fitting. Anti-collision posts or sandbags can be set at the ends of the stacks to reduce the risk of typhoon impact.
IV. Fixation Measures During Transportation
Before transportation, check the connection points between the container and the vehicle. Use strapping bands or steel wire ropes to connect the container to the vehicle's fixation devices (such as corner fittings and chassis hooks), ensuring an even distribution of strapping points. When loading goods, distribute them evenly to avoid center-of-gravity shift. For goods with a high center of gravity, additional fixation is required. If a typhoon warning is issued during transportation, immediately stop at a safe area, increase the number of strapping bands, and check the tightening status.
V. Gap Filling and Internal Reinforcement
If the container is not fully loaded, use inflatable bags, foam, or wooden squares to fill the gaps between the goods and the container walls, reducing displacement space during transportation. For goods that are prone to sliding, lay anti-slip mats or anti-slip paper at the bottom, and use stretch wrap or strapping bands to tightly bundle the layers together to prevent goods from scattering.
