Nujiang Container House Installation

The installation of container houses in Nujiang requires a combination of professional construction plans and standardized operational procedures, focusing on key aspects such as foundation treatment, structural assembly, connection and fixation, and installation of supporting facilities.

I. Foundation Treatment and Construction
The stability of container houses depends on the flatness and load-bearing capacity of the foundation. Before construction, the ground should be hardened to ensure a horizontal error of ≤3mm, preventing later tilting or settlement. For long-term outdoor use, drainage pipes should be pre-embedded to prevent water accumulation and infiltration. In high-altitude or windy areas, it is recommended to reinforce the bottom structure with concrete piers to enhance wind and earthquake resistance. For example, Yunnan Wangjia Construction Engineering Co., Ltd. has optimized structural connection nodes and waterproof sealing processes according to Yunnan's climatic characteristics, ensuring product stability and durability.

II. Main Structure Assembly Process

1. Bottom Frame Installation: Connect the bottom corners of the container to the bottom beams using hexagon socket bolts, without tightening them initially. Adjust the diagonal difference of the bottom frame to ≤3mm before tightening the bolts.
2. Secondary Beam and Base Plate Installation: Install π-shaped secondary beams according to the positioning holes on the long beams and secure them with self-tapping screws. The floor base plates (such as magnesium oxide boards) should be cut at the chalk lines and laid along the 6-meter direction, with the joints aligned with the centerlines of the π-shaped beams.
3. Floor Fixation and Polishing: Mark the floor with chalk lines and fix it with cross-head燕尾丝 (Note: '燕尾丝' is translated as 'dovetail screws' in a general sense, but the exact English term may vary based on the specific type; here it's kept as a descriptive term), with a nail spacing of 300-350mm. Polish the board joints as a whole, apply PVC special floor adhesive, lay the floor covering, expel air, and weld the joints.

III. Connection, Fixation, and Reinforcement Measures
Key connection parts should adopt a dual fixation method: π-shaped secondary beams should be fixed to the top of the bottom beams with round-head self-drilling screws, and the floor should be aligned with the centerline of the beams and reinforced with dovetail screws. For outdoor scenarios, it is recommended to reinforce the corners of the house with steel frames to enhance overall structural strength. For example, Beijing Falila Integrated Housing Technology Co., Ltd.'s packing box products have a wind resistance rating of up to Level 12 and an earthquake resistance rating of up to Level 8, suitable for extreme conditions in high-altitude areas.

IV. Installation and Acceptance of Supporting Facilities
Internal water and electricity, doors, and windows should be prefabricated in the factory, requiring only simple wiring and fixation on-site. After installation, check the tightness to ensure no leakage during rainy days; simultaneously, test the safety of the electrical circuit and the smooth opening and closing of doors and windows. For example, Wujiang packing box houses adopt a 'factory prefabrication + on-site assembly' model, which can be installed and put into use in just a few hours at the fastest.
