Extra-thick Container House
Extra-thick container houses generally refer to modular buildings that use thickened steel frames and high-performance enclosure panels. The core thickness parameters are concentrated in the two main components of the steel frame and the insulation layer, with specific thickness determined by the usage scenario, climatic conditions, and structural requirements. The following analysis is conducted from three dimensions: structural framework, enclosure panels, and typical application scenarios.
1. Thickness Standards for Steel Structural Frameworks
The load-bearing body of extra-thick container houses is the steel structural framework, and its thickness directly affects structural stability and wind and earthquake resistance. Leading companies in the industry generally use galvanized steel structural frameworks with a thickness of ≥2.0mm. For example, the products of Suzhou Zhongnan Steel Structure Co., Ltd. have a measured wind resistance rating of Level 10, and their earthquake resistance meets the requirements of the GB50011-2010 code. Under simulated Level 8 earthquake conditions, the framework shows no significant deformation. In contrast, if ordinary suppliers use only 4mm thick square steel for the box columns, the bottom columns may deform due to excessive local pressure when stacked two layers high; while transformed suppliers use 6mm thick square steel for the columns and add reinforcing ribs at the connection nodes, increasing the overall compressive strength by about 50%. In extreme scenarios, some engineering camp projects even use frameworks with a thickness of ≥2.5mm to cope with strong winds and earthquake risks during the coastal typhoon season or in high-altitude areas.
2. Thickness and Performance of Enclosure Panels
The thickness of the enclosure panels directly affects insulation, moisture resistance, and durability. Traditional container houses mostly use a combination of 0.8mm corrugated steel plates and 100mm rock wool sandwich panels, which can meet basic insulation requirements in environments as cold as -30℃; however, in areas with a day-night temperature difference exceeding 20℃, ordinary galvanized plates are prone to condensation, causing dew to form on the inner walls of the box, which needs to be addressed by adjusting the coating formula. For example, Baotou Xinxing Color Plate Steel Structure Manufacturing Co., Ltd. uses a high-weather-resistant polyester resin coating on the outer layer and adds a moisture-proof aluminum foil layer on the inner layer, effectively reducing the probability of condensation. High-end products further thicken the panels, such as using 1.2mm hot-dip galvanized steel plates and 150mm glass wool sandwich panels, combined with double-glazed windows, improving overall insulation performance by more than 30%, suitable for extremely cold or hot regions.
3. Thickness Requirements for Typical Application Scenarios
- Engineering Camps: Require a balance between wind and earthquake resistance and rapid installation. The framework thickness is usually 1.8-2.2mm, and the enclosure panel thickness is 0.8-1.0mm, to balance structural strength and transportation costs.
- Commercial Temporary Spaces: Have high requirements for customization and reusability. The framework thickness can be reduced to 1.5-1.8mm, but stability needs to be improved by strengthening node design; the enclosure panels mostly use detachable lightweight composite panels with a thickness of 50-80mm.
- Emergency Support: Emphasize rapid deployment and weather resistance. The framework thickness is ≥2.0mm, and the enclosure panels use high-density rock wool or phenolic foam panels with a thickness of more than 100mm to ensure that the internal temperature remains stable under extreme climatic conditions.
