Chongqing Container House Plan

The Chongqing container house plan needs to be designed in combination with functional requirements, structural types, and technical specifications. The following is an explanation from four aspects: classification, design points, technical procedures, and localized services:

I. Selection of Container House Types According to their purposes, they can be divided into five major categories:

1. Office Type: Based on 20-foot and 40-foot standard containers, a single container can independently serve as a project department or construction site command center, while multiple containers can be spliced to expand into a comprehensive office area. For example, the comprehensive office building plan provided by Chongqing Zhongke Container supports modular splicing and functional zoning.
2. Residential Type: Adopting a double-layer structure or packaged container houses, equipped with fire-resistant rock wool interlayers and thermal insulation and soundproof materials, suitable for construction site dormitories or temporary residences. The residential containers provided by Chongqing Le'anju achieve bathroom and bedroom zoning through splicing, with a service life of over 20 years.
3. Commercial Type: Including container shops, exhibition halls, cafes, etc., enhancing visual appeal through glass curtain walls and themed spray paintings. For example, the red-themed container shop by Jiayu Intelligent Manufacturing achieves a balance between commerce and aesthetics with a standard size of 6 meters × 3 meters.
4. Special Type: Such as medical containers, equipment containers, explosion-proof refrigerated containers, etc., requiring customized design to meet special functional requirements.
5. Creative Type: Combining elements such as irregular structures and wood grain finishes, used in cultural and creative parks or brand exhibitions, such as the temporary exhibition hall project by Nice Integrated Housing.

II. Core Design Points

1. Spatial Layout:
   • For small units (e.g., 15㎡), it is recommended to use foldable furniture to improve space utilization;
   • When splicing multiple containers, a staggered floor design can create ventilation and lighting advantages, with a leisure courtyard reserved on the ground floor.
2. Structural Safety:
   • Steel materials must comply with the GB/T 4171 weathering steel standard, and welding points must be polished and coated with epoxy primer;
   • The number of stacked containers should be ≤6 layers, with a height ≤24 meters, and corner fittings should be aligned and locked up and down to ensure stable force transmission.
3. Environmental Adaptation:
   • Thermal insulation: The walls should have an internal insulation layer, and triple-glazed windows should be selected, with better thermal insulation performance than red brick walls;
   • Rust prevention: In humid southern regions, anti-corrosion paint should be reapplied every 7-10 years, and the container base should be raised to avoid moisture erosion.

III. Technical Specifications and Approval Procedures

1. Technical Baselines:
   • Existing containers must pass the GB/T12418 inspection, with no defects in beams and columns and complete corner fittings;
   • Filling materials in crowded places must meet the Class A fire resistance standard (e.g., rock wool/glass wool).
2. Approval Requirements:
   • For rural homesteads, structural drawings must be provided and building approval must be obtained;
   • For leased land, only temporary buildings are allowed, and the contract must specify the nature of use.

IV. Localized Service Resources Local suppliers in Chongqing can provide full-process services:

• Customized Design: Jiayu Intelligent Manufacturing and Pinjian Integrated Housing support personalized needs such as exterior spray painting and glass curtain walls;
• Production and Installation: Zhongke Container and Le'anju have their own factories and professional teams, capable of quickly responding to construction needs;
• Lease and Sale: Multiple companies offer rental services for container mobile homes, with costs 30%-50% lower than traditional buildings.
