Small Container House Installation

The installation of small container houses requires attention to core aspects such as purchase selection, ground treatment, lifting and positioning, and detail handling. The specific process and key points are as follows:

I. Purchase Selection Stage
It is necessary to choose the structural type according to the usage scenario. Welded integral containers are welded into shape as a whole in the factory, with strong resistance to deformation, suitable for scenarios with frequent lifting and movement. Bolt-connected assembled containers use standard plates connected by bolts, with multiple connection nodes in the force path. It is essential to focus on checking the steel wall thickness of the columns and bottom beams (common specifications range from 1.5 mm to 3 mm), with thicker walls providing greater load-bearing redundancy. In addition, the coating process on the container body directly affects its anti-corrosion performance. Hot-dip galvanizing treatment offers a longer anti-corrosion lifespan than cold-dip galvanizing, especially in areas with large temperature differences between day and night and significant humidity changes, where the coating quality directly determines the rusting speed of the container body.

II. Ground Treatment
It is necessary to provide a uniform load-bearing foundation for the container house. If placed directly on soft soil, local pressure can cause uneven settlement of the container body, leading to deformation of doors and windows and cracks in the walls. For long-term fixed use, a concrete strip foundation should be poured, with a recommended width of 30 cm to 50 cm and a depth determined by the local frost depth. The top surface of the foundation should be kept level, with a height difference not exceeding 5 mm. For short-term use scenarios, precast concrete pads or steel plates can be used, with a pad spacing not exceeding 2 m, and a crushed stone leveling layer should be laid beneath each pad.

III. Lifting and Positioning
It is necessary to precisely control the contact state between the container body and the foundation. Container houses typically have four or six lifting points at the bottom. During lifting, sufficient load-bearing steel wires should be used, and it should be ensured that all lifting points are subjected to force simultaneously to avoid distortion of the container body due to unilateral force. After the container body is positioned, the fit between the bottom beam and the foundation pad should be checked immediately. If there is local suspension, it should be filled with thin steel sheets, and a level should be used to check along the longitudinal and transverse directions of the bottom beam, with the levelness error controlled within 2 mm per meter.

IV. Detail Handling
It is necessary to carry out splicing combinations or functional expansions according to actual needs. For example, using 2-3 containers for splicing or staggered stacking can expand functional areas such as living rooms, bedrooms, and bathrooms. The exterior facade can be treated with paint spraying, themed spray painting, cladding, or glass curtain walls, to get rid of the industrial feel and create a villa-like atmosphere.
