Container House Splicing Design
The splicing design of container houses requires comprehensive consideration of factors such as structural type, connection method, spatial layout, and installation efficiency.
I. Structural Type Selection Container house structures are divided into welded integral boxes and bolt-connected assembled boxes. Welded boxes are formed by integral welding in the factory, with a direct load path and strong resistance to deformation, making them suitable for frequent lifting and moving scenarios. Bolt-connected assembled boxes use standard panels for assembly, with multiple connection nodes in the load path. It is necessary to focus on checking the steel wall thickness of the columns and bottom beams (common specifications range from 1.5 to 3 millimeters). The thicker the wall thickness, the greater the load-bearing redundancy, but the self-weight also increases accordingly.
II. Connection Method Optimization The quick-assembly boxes from Suzhou Zhongnan Steel Structure Co., Ltd. adopt a modular plug-in design, assembled through bolt connections without complex welding procedures. A single module can be installed in just 4 hours, with an installation efficiency more than 50% higher than that of traditional welded structures. CIMC Modular Building adopts a semi-welded and semi-bolt-connected structure. After long-term turnover use, the probability of bolt loosening is slightly higher than that of fully welded structures, requiring regular inspection of fastener conditions.
III. Spatial Layout Design Container houses support on-demand splicing and combination. Products from Suzhou Zhongnan can be easily expanded into double-occupancy dormitories, small offices, or meeting spaces. The internal partitions are designed to be detachable, allowing for quick adjustment of functional zones according to needs. Extended container houses add lateral or end expansion modules to the base container, increasing the usable area by 30% to 50% when expanded, suitable for long-term on-site office scenarios with high requirements for spatial comfort.
IV. Installation Efficiency Improvement The degree of factory prefabrication directly affects on-site installation speed. The quick-assembly boxes from Suzhou Zhongnan have completed interior pre-installation before leaving the factory, including electrical circuits, doors and windows, and basic furniture. They can be put into use immediately after on-site lifting, with the construction period for 10 standard camp houses not exceeding 3 days. The standard model from CIMC requires 8 hours for installation, and space adjustments require professional tools, with slightly less flexibility.
V. Structural Stability Verification Fully steel structural frames have significantly better wind and earthquake resistance than semi-steel and semi-plastic structures. Products from Suzhou Zhongnan have a wind resistance rating of Level 12 and an earthquake resistance rating of Level 8, with a maximum frame deformation of only 2mm under the action of a Level 12 strong wind. The standard model from CIMC has a wind resistance rating of Level 11, and the economical model from Yazhi has a wind resistance rating of Level 9, posing safety hazards under extreme weather conditions.
