Container House Beam

The beams of container houses are mainly divided into chassis main beams, chassis secondary beams, and roof structure main beams, and their design needs to consider stress characteristics and structural safety.

Chassis Main Beams and Secondary Beams: The chassis main beam is the core load-bearing component of the container house structure, usually made of I-beams or channel steels, with limited contact area with the ground. In welded container houses, the roof load is transferred to the bottom beams through the side wall columns and then evenly distributed to the ground through the bottom beams. This structure has strong resistance to deformation and is suitable for frequent lifting and moving. The chassis secondary beams assist the main beams in dispersing the load and enhancing overall stability. When purchasing, it is necessary to check the wall thickness of the steel (common specifications range from 1.5 mm to 3 mm). The thicker the wall thickness, the greater the load-bearing redundancy, but the self-weight also increases accordingly.

Roof Structure Main Beams: The roof structure main beam is the main supporting component of the container house roof and needs to withstand external forces such as wind loads and snow loads. Its design needs to work in coordination with the columns and wall panels in the enclosure structure to ensure the stability of the overall structure. In multi-story container buildings, the roof structure main beams also need to consider the connection method with the upper and lower structures to meet seismic design requirements.

Stress Characteristics and Structural Safety of Beams: The beam-column structural parts of container houses are high-risk areas for potential safety hazards, and it is necessary to focus on considering the bending and shear forces of the beams. During structural design, appropriate beam types and steel specifications should be selected according to the usage scenarios of the container houses (such as frequent lifting, long-term fixed placement, etc.). At the same time, the reasonable distribution and cross-sectional selection of columns are also crucial, as they, together with the beams, form a stable load-bearing system.

Manufacturing and Installation Requirements: The beams of container houses are usually completed with core processes such as welding or bolt connections in the factory to ensure component accuracy. During the installation stage, it is necessary to precisely control the contact state between the beams and the foundation to avoid uneven stress caused by local suspension. For container houses used for long-term fixed placement, a concrete strip foundation should also be poured to provide a uniform load-bearing foundation.
