Container House Installation Instructions
The installation of container houses must adhere to technical specifications and safety requirements, with a focus on foundation construction, structural connections, concealed works, and protective measures, as detailed below:
1. Foundation Construction and Drainage & Water Supply
Container houses are constructed with an overall iron structure, and the installation ground must be higher than the surrounding terrain to prevent water accumulation. Drainage ditches should be excavated around the container, and a gable-shaped canopy should be installed on the top during the rainy season to guide rainwater drainage. The water supply system can be addressed by connecting to the municipal water network or adding a water tank, ensuring that pipeline connections are sealed to prevent leakage. The foundation should be poured with concrete to ensure stability and load-bearing capacity, especially for multi-story stacking, where strict control of verticality is necessary to avoid tilting risks.
2. Structural Connections and Seismic Resistance & Anti-loosening
Containers use a light steel frame with rock wool sandwich panels for enclosure. The containers are connected by bolts or welding, and the seismic performance of the joints must be carefully inspected. Connection points should be secured with anti-loosening washers or double nuts and regularly maintained by removing rust and applying paint. Multi-story buildings (such as a three-story main building) require additional horizontal bracing to enhance overall stability, meeting the requirements for seismic resistance of magnitude 7.
3. Quality Control of Concealed Works
Concealed works include electrical and water installations, moisture and waterproofing, and insulation layer construction. Electrical wiring must be enclosed in conduits or cable trays to avoid direct binding to the steel structure, which could pose an electrocution risk; water pipes must undergo pressure testing to ensure no leaks. The waterproof layer should use B1-grade fire-resistant materials, with sealed lap joints and a smoke concentration rating of Q1 to reduce fire hazards. The insulation layer should use 120kg/m³ rock wool boards or Neopor R polystyrene boards, with a thickness of no less than 50mm, effectively isolating extreme temperatures in winter and summer.
4. Fire Protection and Safety Measures
The fire resistance rating must meet Class II standards, with walls and roofs using Class A non-combustible rock wool boards. Windows and doors should be made of aluminum alloy frames with EPDM rubber seals to prevent the spread of fire. Open flame stoves and high-power electrical appliances are prohibited indoors, and the main power switch must be equipped with a leakage protection device. Regularly cut off the power supply to inspect for aging wiring.
5. Maintenance and Usage Restrictions
Users must not alter the layout or dismantle bolt components without authorization to avoid compromising structural stability. Regular maintenance (every 1-2 years) should include rust removal, paint touch-ups, and component reinforcement to extend the service life. Simple iron sheet containers have a lifespan of about 5 years, while customized container houses can last up to 30 years, with maintenance cycles selected based on the material.
