Kaifeng Container House Construction

The construction of container houses in Kaifeng requires custom design and installation by professional companies, utilizing materials such as light steel structures and sandwich panels, and selecting assembled or prefabricated structures based on the intended use, while adhering to construction specifications and safety standards.

1. Construction Entities and Qualification Requirements

The construction of container houses in the Kaifeng area must be undertaken by enterprises with qualifications in steel structure fabrication and installation, such as Henan Wansheng Color Steel House Co., Ltd. and Henan Kuaiyiju Steel Structure Engineering Co., Ltd. These companies offer one-stop services from design and production to installation, and their products are certified by platforms (such as 58.com and Makepolo.com). Service records indicate that they have served over 200 people in the past year, demonstrating high reliability.

2. Material and Structural Selection

1. Main Structure: Using light steel as the framework, connected with bolts to avoid on-site welding, ensuring dismountability and environmental friendliness.
2. Enclosure Material: Sandwich panels (such as color-steel sandwich panels) are used, which combine insulation, fire resistance, and moisture resistance, with a service life of up to 20 years.
3. Structural Types:
   • Assembled Type: Color steel plates are fixed on-site, suitable for cost-effective and practical needs, but not ideal for frequent relocation.
   • Prefabricated Type: The enclosure structure is assembled with bolts and inserted into reserved frame slots, facilitating quick assembly and disassembly, suitable for temporary or mobile scenarios.
   • Lifting Type: The overall structure is stable and can be lifted multiple times, suitable for users requiring frequent relocation.

3. Construction Process and Specifications

1. Design Phase: Customize dimensions and layout based on the intended use (such as temporary buildings, offices, or residences), adhering to wind resistance (75km/h) and snow load (100kg/m²) standards.
2. Installation Phase:
   • Foundation Treatment: Ensure the ground is level and pour a concrete foundation if necessary.
   • Framework Assembly: Assemble the light steel framework according to the design drawings, checking for verticality and levelness.
   • Enclosure Installation: Fix the sandwich panels, paying attention to joint sealing to prevent leakage.
3. Acceptance Criteria: Inspect structural stability, door and window sealing, and electrical circuit safety to ensure compliance with the "Design Specifications for Temporary Buildings."

4. Safety and Compliance Points

1. Land Approval: If used for long-term residence or commercial purposes, temporary land use or construction permits must be obtained in advance.
2. Fire Protection Requirements: The core material of the sandwich panels must be fire-resistant, and fire extinguishing equipment should be provided indoors.
3. Environmental Protection Requirements: Minimize dust during construction, classify and dispose of waste, and comply with Kaifeng's environmental regulations.
