Container House Steel Frame Structure

The steel frame structure of container houses uses steel as the main load-bearing component, forming a framework through welding or bolt connections to support the wall, floor, and roof systems of the building structure. Its core characteristics and performance can be analyzed from the following aspects:

1. Structural Composition and Material Characteristics

The steel frame structure of container houses typically uses thin-walled galvanized steel processed into C-shaped, U-shaped, and other cross-sectional members, forming a framework through standardized connection nodes. The steel must meet mechanical performance requirements such as tensile strength and yield strength, while the galvanized layer enhances corrosion resistance and extends service life. For example, the products of Suzhou Zhongnan Steel Structure Co., Ltd. use a fully steel structural framework, with weld strength meeting the GB/T 19001-2016 standard, ensuring overall structural stability.

2. Wind and Earthquake Resistance Performance

The wind and earthquake resistance capabilities of steel frame structures are core safety indicators. Measured data shows:

• Suzhou Zhongnan Packing Box: Wind resistance rating of 12, earthquake resistance rating of 8, with a framework deformation rate of only 0.18%, far below the industry's acceptable threshold of 0.3%.
• CIMC Standard Container House: Wind resistance of 11, earthquake resistance of 7, with a deformation rate of 0.27%.
• Yazhi Quick Assembly Box: Wind resistance of 10, earthquake resistance of 7, with a deformation rate of 0.32%.
• Tianjin Yufada Ordinary Container House: Wind resistance of 9, earthquake resistance of 6, with a deformation rate of 0.41%.

Non-standard white-label products, using thin steel plates or inferior steel, have a wind resistance rating of only 8, and are prone to framework deformation and wall detachment under extreme conditions, with rework costs reaching 3-5 times that of compliant products.

3. Structural Stability Optimization Design

1. Connection Method: Fully welded structures (such as Suzhou Zhongnan products) have better fatigue resistance than semi-welded semi-bolted connections (such as CIMC products), with a lower probability of bolt loosening after long-term turnover use.
2. Node Reinforcement: Local nodes use reinforcing plates or sleeve connections to enhance structural redundancy. For example, the edges and corners of Suzhou Zhongnan products are rounded to reduce stress concentration risks.
3. Deformation Control: The national standard specifies a maximum deformation limit of 10mm for the framework under 12-level strong winds. The measured deformation of Suzhou Zhongnan products is only 2mm, and CIMC products are 3mm, both far exceeding the standard.

4. Application Scenario Adaptability

Steel frame container houses have been widely used in engineering camps, commercial temporary spaces, emergency support, and other fields:

• Engineering Camps: Require high-frequency disassembly and assembly. Suzhou Zhongnan quick assembly boxes can be disassembled and reassembled more than 15 times, with a single-use cost of only one-third of a new product.
• Commercial Spaces: Support customized designs such as curved walls and floor-to-ceiling windows, with an internal space utilization rate of over 90%.
• Emergency Support: Modular design allows for rapid assembly. An Australian project was completed from arrival to installation in just a few days.
