Container House Load-Bearing Test
The load-bearing test of container houses requires a comprehensive evaluation based on structural type, material specifications, and testing standards. The typical load-bearing range is between 150kg/㎡ and 3000kg/㎡, with specific values depending on actual test data.
1. Impact of Structural Type on Load-Bearing Capacity
The structural type of a container house directly affects its load-bearing capacity. Fully steel-structured frame container houses (such as those from Suzhou Zhongnan Steel Structure Co., Ltd.) form an overall load-bearing system through steel section welding or bolt connections, offering strong resistance to deformation and a ground load-bearing capacity ranging from 200kg/㎡ to 3000kg/㎡. For example, a certain fully steel-structured container house can withstand a uniformly distributed load of 14,000kg in actual tests (according to ISO1496 standards), while modularly designed container buildings, which combine reinforced foundation anchor bolts with embedded anchors, can achieve a maximum load-bearing capacity of up to 3000kg/m². In contrast, semi-steel and semi-plastic structured container houses have significantly reduced load-bearing capacities, with some products having a ground load-bearing capacity of less than 150kg/㎡, posing safety risks in scenarios with dense personnel or equipment stacking.
2. Key Roles of Material Specifications and Processes
Material thickness and connection processes are core factors in load-bearing capacity. The thickness of steel for main beams and columns directly affects structural strength, with common specifications ranging from 1.5mm to 3mm. Thicker walls provide greater load-bearing redundancy. For example, a certain brand of container house uses 3mm thick steel and shows a deformation of only 0.3mm under a 1.2-ton engineering vehicle rolling test, well below industry thresholds. The fullness of welding processes is also crucial, as incomplete welds or weld defects can significantly reduce load-bearing capacity. Additionally, coating processes (such as hot-dip galvanizing) can extend the service life of steel, preventing load-bearing degradation due to corrosion.
3. Testing Standards and Reference to Actual Test Data
Load-bearing tests must adhere to national standards or industry norms. For example, GB50009-2012 'Building Structural Load Code' requires a minimum ground load-bearing capacity of 150kg/㎡ for temporary buildings, with higher standards needed for extreme conditions (such as earthquake zones or high-wind areas). Actual test data shows that a certain brand of container house remains structurally stable under simulated tests of 12-level gales and 7-level earthquakes, with a ground load-bearing capacity of 200kg/㎡, meeting the needs of engineering camps. Another product, through optimized design, increases its load-bearing capacity to 3000kg/m², capable of withstanding heavy equipment or stacked loads.
