Firmness of the Bottom Plate of Container Houses

The firmness of the bottom plate of container houses can be ensured through various aspects such as structural design, material selection, and installation techniques:

Structural Design

Some container houses adopt patented reinforcement structural technologies. For example, Yashun Light Steel's "A Reinforcement Structure for Container Houses" utilizes components such as a raft foundation (concrete structure), support column bases, and embedded parts. The support column bases are arranged at intervals at the lower end of the container body, with corresponding embedded parts placed within the raft foundation. The upper end of the embedded parts features a welding surface, to which the support column bases are welded and fixed. This design enhances the connection firmness and stability between the container body and the ground, mitigating the impact of external factors such as wind on the container house and providing excellent earthquake resistance. Additionally, there is a connection structure for the bottom sealing plate of container houses, which combines components such as a central positioning plate, connecting side plates, support cross plates, and connecting plates. This design facilitates easy assembly and disassembly and allows for adjustment of the bottom plate spacing according to the size of the container house, offering effective support.

Material Selection

Container houses primarily use steel as the structural support, including channel steel, angle steel, and steel plates. These steel materials possess high strength and corrosion resistance, ensuring the structural safety of the house. For instance, the columns of container houses have a thickness of no less than 1mm. Channel steel with dimensions of 5X10 is selected for welding the main cross beams around the upper and lower bases of the container. Corrugated plates are formed by pressing thin steel plates, with a market thickness of approximately 0.6mm, available in both black iron and galvanized plate materials. The selection of these materials provides a fundamental guarantee for the firmness of the bottom plate.

Installation Techniques

During the installation process, various techniques are employed to ensure the firmness of the bottom plate. For example, in the installation of assembled container houses, the bottom corners are first connected to the bottom beams using hexagon socket bolts, which are initially left loose. After adjusting the frame to ensure that the diagonal difference of the bottom frame is ≤3mm, the bolts are then tightened. The π-shaped secondary beams are installed and fixed according to the positioning hole positions on the long beams, with the tops of the π-shaped secondary beams also fixed to the bottom beams. The floor base plates are laid along the 6-meter direction, with operations such as corner cutting, marking, floor laying, and nail fixing carried out as required. Overall operations such as floor grinding, gluing, and laying of floor coverings ensure the stable installation of the bottom plate.
