Tonghua Container House Construction

The construction of container houses in Tonghua mainly involves standardized and modular construction processes, with core steps including factory prefabrication, on-site assembly, and customized design. The construction period is short, and the houses are movable and reusable.

1. Construction Entities and Process Characteristics

In the Tonghua region, the construction of container houses is mainly led by professional manufacturers, such as Jilin Shengquan Color Steel Co., Ltd. and Shenyang Yingchuang Color Steel Installation Co., Ltd., which adopt standardized steel-structure modular construction technology. The core processes include:

1. Factory Prefabrication: In the workshop, tasks such as welding of steel-structure frames, prefabrication of wall and roof panels (commonly using fire-resistant polyurethane sandwich panels or color steel plates), and embedding of water and electricity pipelines are completed to ensure the accuracy and quality stability of components.
2. On-site Assembly: After transporting the prefabricated modules to the construction site, inter-layer connections and overall assembly are carried out through lifting, reducing on-site wet work. The construction period can be shortened to several days to several weeks. For example, the Nantong COSCO Shipping project built a three-story office building in 11 days using 96 containers, demonstrating the efficiency of modular construction.
3. Customized Design: Module dimensions, materials, and functional configurations are adjusted according to usage scenarios. For example, packing-box container houses can be used independently or stacked and combined, suitable for construction site dormitories, office areas, emergency shelters, and other needs.

2. Material and Performance Requirements

1. Structural Materials: Mainly hot-dip galvanized cold-formed sections or high-quality steel are used to ensure load-bearing capacity and durability. For example, Qidong Container Factory uses 6mm steel plates bent into beam bodies, replacing traditional heavy square tubes to achieve a balance between lightweight design and stability.
2. Enclosure Systems: Color steel plates or fire-resistant sandwich panels are commonly used for walls and roofs, providing thermal insulation, fire resistance, wind erosion resistance, and sound insulation to adapt to temperature differences ranging from -30℃ to 50℃.
3. Connection Nodes: High-precision welding or bolt connections are used to ensure inter-layer stability and reduce on-site errors. The Nantong project adopted factory-prefabricated “6-meter + 14-meter” integrated modules, requiring only inter-layer connections after on-site lifting, improving construction efficiency.

3. Application Scenarios and Advantages

1. Temporary Building Sector: Widely used in construction sites for temporary offices, worker dormitories, emergency rescue shelters, and other scenarios, supporting rapid deployment and repeated disassembly and assembly. The material recycling rate exceeds 85%.
2. Economic and Environmental Benefits: Compared to traditional buildings, container houses can save over 30% in costs and align with green building concepts, reducing construction pollution and resource waste.
3. Flexibility and Scalability: Modular design supports multi-story stacking and functional combinations, meeting diverse needs such as offices, dormitories, and commercial spaces, with a design service life of over 15 years.
