Construction of Container Houses in Mishan City

The construction of container houses in Mishan City must adhere to professional procedures and comply with relevant regulations. The specific steps are as follows:

1. Preliminary Planning and Design

1. Confirmation of Requirements and Regulations: Determine the size (e.g., 20-foot or 40-foot standard containers), quantity, and layout of containers based on their intended use, with a focus on local building codes, particularly requirements for load-bearing capacity, fire resistance, thermal insulation, and earthquake resistance. It is recommended to consult the Mishan City Housing and Urban-Rural Development Bureau or a professional design institute in advance to ensure compliance with regulations.
2. Assessment of Site Conditions: Determine the type of foundation (e.g., strip foundation or independent foundation) based on geological reports. The foundation depth must exceed the local frost line (generally not less than 0.5 meters), and anchor bolts should be pre-embedded for securing the containers.

2. Container Body Treatment and Modification

1. Structural Reinforcement: Perform sandblasting and rust removal on the exterior of the container body, and apply anti-rust primer (e.g., epoxy zinc-rich paint) and topcoat. After cutting openings for doors and windows, reinforce the surrounding areas with square steel or channel steel to restore structural strength.
2. Thermal Insulation and Waterproofing: Install a 50mm-100mm thick thermal insulation layer (e.g., rock wool or extruded polystyrene board) inside the container, and apply waterproofing membranes or spray polyurethane waterproofing on the exterior to ensure thermal insulation and moisture resistance.

3. Lifting and Fixing

Use a truck crane with a capacity of over 25 tons to lift the container by attaching special lifting fixtures to the corner fittings at all four corners. After positioning, secure the corner fittings to the pre-embedded bolts in the foundation with nuts, ensuring the container is stable and does not wobble.

4. Interior Renovation and System Installation

1. Water and Electricity Piping: Lay concealed pipes within the walls, using flame-retardant wires (e.g., ZR-BV wires) and PPR water supply pipes. Install distribution boxes, switches, sockets, and water supply and drainage systems.
2. Flooring and Walls: Lay tiles or wooden flooring, and use fire-resistant materials such as gypsum board or integrated wall panels for the walls. All materials must comply with the requirements of the 'Code for Design of Buildings' (GB 50016).
3. Door and Window Installation: Choose security doors and thermal-break aluminum windows, ensuring tight sealing to prevent air and water leakage.

5. Exterior Decoration and Final Touches

Install decorative panels such as metal carved panels or wood-plastic panels, or spray stone-like paint to enhance aesthetics. Complete roof waterproofing, installation of drainage troughs, and site cleanup.

6. Industry Standards and Precautions

China currently lacks a dedicated national standard for container houses, but standards such as the 'Code for Design of Steel Structures' (GB 50017) and the 'Code for Seismic Design of Buildings' (GB 50011) must be followed. Focus on checking the strength of steel frame connectors and fire resistance ratings. Before construction, it is advisable to refer to the renovation project of the container yard at Mishan Station to ensure that supporting facilities (e.g., fire protection, communication) are constructed simultaneously.
