Double-Deck Container House Production

The production of double-deck container houses requires the integration of modular design concepts and industrial production processes, achieving efficient space utilization through the combination of standardized components. The core steps include design planning, material selection, structural processing, functional integration, and on-site installation.

1. Design Planning Phase

Function zones and spatial layouts must be determined based on the usage scenario. For example, construction site camps often adopt a tiered design with offices on the lower level and accommodations on the upper level; commercial exhibition spaces achieve transparency through large-span glass curtain wall renovations. Shandong Guoheng Intelligent Manufacturing Co., Ltd.'s standardized products offer multiple specifications ranging from 6 to 12 meters, supporting horizontal and vertical combinations. With a single-story height of 2.9 meters, the double-story combination can reach a three-dimensional space of 5.8 meters. During design, emphasis should be placed on load optimization, using reinforced steel and special node treatments to increase load-bearing capacity by 40% compared to conventional products, ensuring that the upper and lower levels can independently support different functional zones.

2. Material Selection and Structural Processing

The main structure uses Q355B high-strength steel, paired with 50mm thick rock wool sandwich panel walls (fire rating B1) and 500kg/m² load-bearing floors. Shandong Guoheng achieves component processing accuracy within ±1mm and material utilization rates of 95% through CNC cutting machines and automatic welders. Key processes include:

1. Rust Prevention: The coating thickness on the container surface is ≥120μm, adaptable to environments ranging from -30℃ to 50℃;
2. Connection System: Patented prefabricated connectors are used to enable quick locking and disassembly of upper and lower containers, reducing on-site installation time by 60%;
3. Climate Adaptability: Double-layer insulation and moisture-proof coatings, combined with adjustable ventilation systems, ensure normal operation in extreme weather conditions.

3. Functional Integration and Modular Production

The industrial production system supports integrated designs such as pre-embedded plumbing and electrical lines and standardized window and door interfaces. For example, the commercial upgrade version is equipped with a pre-installed electrical system that can be directly connected to the municipal power grid; the special custom series meets professional scenario requirements such as medical containers and laboratories through structural reinforcement. Shandong Guoheng's automated production line has an annual capacity of 5,000 standard containers, and each product must pass 12 inspection procedures, including pressure testing and weld imaging, before leaving the factory.

4. On-Site Installation and Acceptance

The installation process includes foundation treatment, container lifting, connector fixation, and functional debugging. Attention should be paid to:

1. Foundation Requirements: Choose concrete foundations or steel structure supports based on geological conditions, ensuring a horizontal error of ≤5mm;
2. Safety Inspections: Connectors must be tightened every six months, and anchoring devices should be reinforced before strong typhoon warnings;
3. Compliance: It is necessary to confirm local temporary building approval policies in advance and prohibit unauthorized cutting of load-bearing walls.

This solution extends the service life by 3-5 times compared to traditional portable cabins, reduces overall costs by 30%-40%, and shortens the construction period by 70%. It is particularly suitable for temporary building projects with limited budgets but a pursuit of quality.
