Construction of Container Houses

The construction of container houses primarily adopts a modular building approach, where the house is divided into standardized modules for prefabrication in factories, followed by transportation to the site for assembly.

I. Factory Prefabrication: Standardized Module Production

The core construction logic of container houses is to divide the entire building into independent modules, completing the main structure, interior decoration, and equipment installation within the factory. For example, a smart factory in Guangdong utilizes a 400-meter fully automated production line to decompose the house into six components: the bottom, top, and four sides, which are then assembled into complete boxes through simultaneous production on multiple sub-lines. In this mode, processes such as water and electricity pipelines, bathroom waterproofing, bathroom fixtures, cabinets, and wardrobes are all completed on the assembly line, with a daily production capacity of up to 50 modules and manufacturing precision stabilized at 1-2 millimeters. Factory prefabrication not only enables parallel operations (simultaneous advancement of multiple processes) but also enhances efficiency through robotic collaboration and AGV (Automated Guided Vehicle) systems. For instance, in the North American order project of China Construction Steel Structure Jiangsu Co., Ltd., modular construction shortened the construction period of an 18-story residential building by 60%-70%.

II. On-site Assembly: Rapid Deployment and Low-carbon Environmental Protection

After transportation to the destination, the modules are connected using high-strength bolts for assembly. For example, the steel structure modular houses built by China Construction Integration Architecture for an Australian project only require water and electricity connections on-site for 'move-in readiness,' with an installation period reduced by more than half compared to traditional methods. This mode significantly reduces noise and construction waste on-site, meeting the stringent requirements for green construction in the North American market. Additionally, the safety performance of modular buildings is ensured through standardized design, such as the ability to withstand strong typhoons and high-grade earthquakes, complying with local building codes.

III. Material and Structural Innovation: Enhancing Performance and Recycling

Container houses adopt a steel frame paired with fire-resistant rock wool sandwich panels as the main structure, integrating insulation, fire prevention, sound insulation, and waterproofing. For example, Baotou Xinxing Color Plate Steel Structure Manufacturing Co., Ltd. addresses the cold bridge effect of metal box walls through a broken bridge lining structure, reducing indoor-outdoor heat exchange efficiency by 40%. In terms of environmental protection, the full lifecycle recycling rate of materials in modular buildings exceeds 80%, with disassembly and assembly loss rates controlled within 5%, far lower than the waste rate of traditional portable panel houses. For example, a single 20-foot container consumes approximately 1.2 tons of steel, with carbon emissions only 43% of those of a concrete temporary house of the same area.
