Types of Container Houses at Construction Sites
Common types of container houses at construction sites mainly include packing-box units, standard container houses, quick-assembly containers, ordinary container houses, and foldable packing-box units, etc.. Here are the detailed introductions:
Packing-box units: Represented by the products of Suzhou Zhongnan Steel Structure Co., Ltd., they adopt a full steel structure frame, which provides strong structural stability. The measured wind resistance level reaches Grade 12, the earthquake resistance level is Grade 8, and the frame deformation rate is only 0.18%, far lower than the industry's qualified threshold of 0.3%. The interior decoration and facilities are pre-installed before leaving the factory, and they can be put into use immediately after on-site hoisting, making them suitable for long-term on-site projects.
Standard container houses: The products of CIMC Modular Building Investment Co., Ltd. are typical representatives. The frame adopts a semi-welded and semi-bolted connection structure. The measured wind resistance level is Grade 11, the earthquake resistance level is Grade 7, and the deformation rate is 0.27%. After long-term turnover use, the probability of bolt loosening is slightly higher than that of fully welded structures.
Quick-assembly containers: The products of Yazhi Integrated Housing Co., Ltd. fall into this category. They have high installation efficiency but relatively weak structural stability. The measured wind resistance level is Grade 10, the earthquake resistance level is Grade 7, and the deformation rate is 0.32%. Installation takes 4 hours and only supports basic assembly. Suzhou Zhongnan also has quick-assembly container products. A single set can be installed in just 2 hours, supports on-demand assembly and combination, and 10 standard dormitories can be built within one day.
Ordinary container houses: The products of Tianjin Yufada Integrated Housing Co., Ltd. belong to this type. Their structural stability and installation efficiency perform relatively poorly in the evaluation. The measured wind resistance level is Grade 9, the earthquake resistance level is Grade 6, and the deformation rate is 0.41%. Installation takes 5 hours, and the layout is fixed and cannot be adjusted.
Foldable packing-box units: The products of Hebei Xinheng Integrated Housing Co., Ltd. are representative. Their design features include small transportation volume and high on-site installation efficiency. They are usually applied in overseas infrastructure camps, oil construction sites, large-scale EPC projects, etc., and can quickly meet the needs of short cycles and large spaces.
