How to Lay the Floor of a Container House

The floor laying of a container house should be carried out in accordance with standardized procedures. Commonly used materials include magnesium oxide board, fiber cement board, patterned aluminum plate, etc. The specific laying steps and material characteristics are as follows:

I. Floor Laying Steps

1. Baseboard Pre-processing
   Taking magnesium oxide board as an example, the floor baseboard should be laid along the 6-meter direction of the container. The baseboards at both ends should be cut at an angle according to the pre-drawn chalk lines and fixed using pre-punched holes.

2. Marking the Center Line of the π-shaped Beam
   Mark the center line of the π-shaped beam in the container to provide a positioning reference for subsequent floor splicing and nailing.

3. Floor Splicing and Fixing
   Start laying the floor from one end, ensuring that the splicing joint coincides with the center line of the π-shaped beam. After laying, snap chalk lines along the center line mark (two chalk lines are required at the splicing joint, each deviating 20mm from the center line), and fix with st4.2*38 cross-head燕尾丝 (cross-head dovetail screws). The nailing interval should be controlled between 300-350mm.

4. Grinding and Gluing
   Grind the entire floor, especially the splicing joints, apply PVC special floor adhesive, wait for 10-15 minutes, then lay the floor covering, and expel the air between the floor covering and the baseboard. If conditions permit, welding treatment can be performed on the splicing joints of the floor covering to enhance sealing.

II. Commonly Used Floor Materials and Their Characteristics

1. Magnesium Oxide Board
   It has excellent fire resistance, with a fire-resistant temperature of up to 1000-2000℃. It is also waterproof, moisture-proof, not prone to deformation or mildew, and is suitable for scenarios with high safety requirements.

2. Fiber Cement Board
   Based on cement and reinforced with mineral fibers, it has fire resistance, moisture resistance, heat insulation, and sound insulation functions. It is lightweight, high-strength, easy to construct, and has a long service life, making it an economical and practical choice.

3. Patterned Aluminum Plate
   It has outstanding anti-slip performance and is commonly used for the floors of bathrooms or integrated houses that require anti-slip properties. It also has corrosion resistance and is easy to clean.

4. Fireproof Board (such as glass fiber material)
   It has a fire resistance rating of A1, does not burn at 800℃, and has no flames at 1200℃. It is also waterproof, lightweight, and impact-resistant, suitable for container houses with strict fire prevention requirements.

III. Precautions

• Ensure that the interior of the container is dry and flat before laying the floor to avoid floor deformation due to foundation problems.
• Select materials according to the usage scenario. For example, in humid environments, fiber cement board or fireproof board should be preferred, and patterned aluminum plate should be selected for anti-slip requirements.
• Strictly follow the nailing interval and splicing specifications during construction to ensure the stability of the floor.
