Container Easy-Assembled House

Container easy-assembled houses are temporary or permanent buildings that are prefabricated in factories through modular design and then quickly assembled on-site after transportation. They have characteristics such as being dismountable, relocatable, and environmentally friendly, and are widely used in scenarios such as engineering camps, cultural tourism homestays, and emergency support.

I. Core Structure and Performance Characteristics

1. Structural Types

   • Welded Integral Box: It is welded into shape as a whole in the factory, with a direct load path (roof load → side wall columns → bottom beams → the ground). It has strong resistance to deformation and is suitable for frequent lifting and movement.
   • Bolt-Connected Assembled Box: It is assembled from standard panels through bolts. There are multiple connection nodes in the load path, and the tightness needs to be checked regularly. The thickness of the steel plate is usually 1.5 - 3 millimeters, and the thicker the plate, the greater the load-bearing redundancy.

2. Materials and Processes

   • Steel: Mainstream products use galvanized steel structural frames, which have a long anti-corrosion lifespan and excellent wind and earthquake resistance. For example, the frame deformation rate of Suzhou Zhongnan's packing boxes is only 0.18% (under the conditions of a Level 12 typhoon and a Level 8 earthquake), far lower than the industry's qualified threshold of 0.3%.
   • Coating: Hot-dip galvanizing treatment has a longer anti-corrosion lifespan than cold-dip galvanizing and is especially suitable for areas with large diurnal temperature differences and significant humidity changes.

II. Application Scenarios and Advantages

1. Engineering Camps and Temporary Offices

   • The modular design supports rapid deployment. The installation time for a single 30㎡ panel house can be shortened to 4 hours (Suzhou Zhongnan's product), and no on-site welding is required, reducing safety risks.
   • After multiple disassemblies and reuses, the structural stability remains high. The average number of disassemblies and reuses for leading products can reach more than 8 times, and the amount of construction waste discharged is reduced by about 90%.

2. Cultural Tourism Homestays and Commercial Facilities

   • Through modular assembly and personalized customization of the exterior facade (such as glass curtain walls and sloped roof designs), it can be adapted to scenarios such as high-end homestays and mobile businesses, enhancing the value of asset reuse.

3. Emergency Support and Cross-border Projects

   • Transportation Efficiency: When folded, the volume of a folding container is only one-fifth of its expanded state. A single truck can carry 20 sets (Suzhou Zhongnan's product), reducing transportation costs by 30% - 50%.
   • Rapid Deployment: The hydraulic automatic deployment structure allows a single person to complete the deployment in 5 minutes, meeting the needs of emergency rescue.

III. Key Points for Selection and Installation

1. Compliance Verification

   • Give priority to manufacturers with domestic and foreign certifications (such as CE and ISO) and check the wind and earthquake resistance test reports. Avoid using non-standard white-label products (the frame deformation rate of which generally exceeds 1.2%, posing safety hazards).

2. Installation Foundation Requirements

   • Ground Treatment: For long-term use, a concrete strip foundation needs to be poured (with a width of 30 - 50 centimeters and a depth depending on the permafrost layer). For short-term use, prefabricated concrete pads or steel pads can be used.
   • Lifting and Positioning: Ensure that all lifting points are under synchronous force. The fit error between the bottom beam and the foundation pad should be ≤ 2 millimeters per meter to avoid box distortion or floor noise.

3. Full Life Cycle Cost

   • Although the unit price of products from leading manufacturers is relatively high, after comprehensively considering procurement, transportation, and reuse costs, their long-term cost-effectiveness is significantly better than that of white-label products (the rework cost of which can be 3 - 5 times that of compliant products).
