Container House Welding Drawing

Container house welding drawings typically include key elements such as structural design descriptions, floor plans, elevation drawings, structural diagrams, and detailed node drawings. They must specify steel grades, weld requirements, and connection methods, and comply with international or domestic container building codes.

I. Core Content of the Drawings

1. Structural Design Description
   It is necessary to specify the main structural materials (e.g., Q345 steel), electrode types (e.g., E50 type), welding process requirements (e.g., full-penetration welding), and anti-corrosion treatment methods. For example, the main structure of a 2500-series container house consists of a bottom frame, columns, and a top frame made of steel structures, which are connected by welding. The roof panel is a 50mm-thick double-sided color-steel sandwich panel, and the wall panel is a 50mm-thick EPS double-sided color-steel sandwich panel.

2. Floor and Elevation Layout Drawings
   The floor plan should indicate the combination method of container modules (e.g., single-container or multi-container assembly), the locations and dimensions of doors and windows. The elevation drawing should display the exterior materials (e.g., steel plates, sandwich panels), decorative details (e.g., stickers or paint), and overall appearance. For example, container houses can achieve personalized designs through cutting openings, painting, and adding decorative stickers.

3. Structural and Detailed Node Drawings
   The structural diagram should detail the dimensions of the steel framework (e.g., channel steel specifications of 5X10), connection methods (e.g., bolting followed by welding), and weld types (e.g., full-penetration welding). The detailed node drawing should provide an enlarged view of the welding details at key connection points (e.g., between the bottom frame and columns, top frame and wall panels) to ensure structural strength. For example, all panel contact areas must be fully welded, and welding should only commence after bolts are correctly positioned.

II. Welding Process and Material Requirements

1. Steel and Electrode Selection
   The steel must comply with international standards (e.g., ISO standards for container steel), and the electrode type must match the base material (e.g., E50 electrodes for Q345 steel). For example, the container steel structure design explicitly requires the use of Q345 steel and E50 electrodes.

2. Welding Difficulty and Construction Conditions
   The welding difficulty should be assessed based on structural complexity (e.g., general or high difficulty), and the construction unit must possess the corresponding technical capabilities (e.g., welder qualifications, equipment precision). For example, welding for container houses must ensure weld quality to avoid structural failure due to welding defects.

III. Code and Standard References

The drawings must comply with international standards (e.g., ISO container dimension specifications) or domestic building codes (e.g., steel structure design standards), specifying the container's load-bearing capacity, dimensions, and assembly methods. For example, an international standard 20-foot container has a load capacity of 25 tons, while a 40-foot container has a load capacity of 45 tons. Container house design should consider modular assembly to expand spatial adaptability through container combination.
