Container Module House Design

The design of container module houses requires comprehensive consideration of factors such as material selection, structural mechanics, thermal performance of the enclosure structure, seismic resistance of connection nodes, and modular production and installation.

I. Material Selection and Structural Mechanics The main frame of container module houses should be made of high-strength weathering steel, such as Q355B grade, which has a yield strength approximately 30% higher than that of ordinary carbon steel and can support a box structure with a length-to-width ratio close to 2:1. A self-balancing system is formed through rigid connections between corner fittings and side beams. The top longitudinal corrugated plates disperse stress through their corrugated geometry, avoiding local buckling and reducing material usage by about 15%. For example, Yiqi Company adopts this design to achieve structural stability without external support.

II. Thermal Performance of the Enclosure Structure The enclosure structure should adopt a composite construction to enhance thermal insulation performance. For example, in the three-layer structure of "rock wool - air layer - aluminized zinc plate", the thickness of the rock wool layer is controlled between 75 and 100 millimeters, with a thermal conductivity lower than 0.040 W/(m·K). The 5-millimeter air layer in the middle suppresses convective heat transfer through a closed cavity, resulting in an overall heat transfer coefficient (U-value) lower than 0.5 W/(m²·K). This design reduces the risk of condensation in Inner Mongolia's low-temperature winter environment and extends the service life of the steel structure.

III. Connection Nodes and Seismic Resistance For areas with high seismic design intensity, connection nodes should adopt a dual-fixing mode of "wedge-shaped lock + high-strength bolts". The wedge-shaped lock is designed with a 15-degree inclined surface, which generates a self-locking effect under horizontal shear forces. During a simulated rare earthquake of magnitude 8, the displacement is controlled within 3 millimeters, which is about 40% better than the deformation amplitude of conventional welded nodes. This design facilitates repeated assembly during secondary relocation and reduces construction waste generation.

IV. Modular Production and Installation Container module houses should be completed with main structures, water and electricity pipelines, and interior decoration in the factory before being transported to the site for assembly. For example, a domestic smart factory can produce up to 50 modules per day, with manufacturing precision stably controlled within 1-2 millimeters. During on-site installation, a 30㎡ prefabricated house from Suzhou Zhongnan Steel Structure Co., Ltd. can be installed in just 4 hours without on-site welding, significantly reducing safety risks.
