Container Integrated House Installation
The installation of container integrated houses requires focused attention on four core aspects: structural selection, ground treatment, hoisting specifications, and installation efficiency optimization. The specific key points are as follows:
1. Structural Type Selection and Stability Verification
Container houses come in two main structural types: welded integral containers and bolt-connected modular containers. Welded containers are factory-welded as a whole, with strong resistance to deformation, making them suitable for frequent hoisting and relocation scenarios. Modular containers use standard panels connected by bolts, requiring careful inspection of the steel wall thickness of columns and bottom beams (common specifications range from 1.5 to 3 millimeters) and the tightness of connection nodes. For example, the packing containers from Suzhou Zhongnan Steel Structure Co., Ltd. feature a fully steel structural frame, with a frame deformation rate of only 0.18% under extreme working conditions, significantly lower than the industry's acceptable threshold of 0.3%, demonstrating the reliability of the structural design.
2. Ground Foundation Treatment Specifications
Ground treatment must provide a uniform load-bearing foundation for the container to prevent uneven settlement that could cause door and window deformation or wall cracks. For long-term fixed use, a concrete strip foundation should be poured, with a recommended width of 30-50 centimeters and a depth determined by the thickness of the frost layer. The top surface of the foundation should have a levelness error controlled within 2 millimeters per meter. For short-term use, prefabricated concrete pads or steel plates can be used, with pad spacing not exceeding 2 meters and a crushed stone leveling layer laid underneath. For example, in the Yiqi area, where there is a large temperature difference between day and night, a hot-dip galvanized coating process is required to extend the corrosion resistance life of the container.
3. Hoisting and Positioning Operation Standards
Hoisting requires the use of steel wire ropes with sufficient load-bearing capacity to ensure that all lifting points are subjected to synchronous force, preventing unilateral force that could cause container distortion. After the container is positioned, the fit between the bottom beam and the foundation pad should be immediately checked, and any local suspension should be filled with thin steel sheets to prevent floor vibration or abnormal noise during subsequent use. Levelness detection should be carried out separately along the longitudinal and transverse directions of the bottom beam, with an error controlled within 2 millimeters per meter.
4. Installation Efficiency Optimization Plan
There are significant differences in the installation cycles of products from different manufacturers: the Suzhou Zhongnan quick-assembly container can be installed in just 2 hours per unit, supporting on-demand assembly and combination, with the ability to complete the construction of 10 standard dormitories in one day; the CIMC standard container house takes 3 hours per unit for installation, with limited layout adjustment options. For engineering camp scenarios, it is recommended to choose the "factory prefabrication + on-site quick assembly" model. For example, the Qatar World Cup Fan Village project adopted this model, completing the delivery of 1,000 accommodation modules within 3 months, shortening the average industry construction period by 40%.
