Container House Residential Installation
The installation of container houses for residential purposes requires comprehensive consideration of key aspects such as structural stability, installation efficiency, foundation treatment, and concealed works. The specific installation points are as follows:
1. Structural Stability and Selection
Under extreme working conditions, priority should be given to products with qualified wind and earthquake resistance performance. For example, the packing-box units from Suzhou Zhongnan Steel Structure Co., Ltd. adopt a full steel structure frame, with a wind resistance rating of Level 12 and an earthquake resistance rating of Level 8. The frame deformation rate is only 0.18%, far lower than the industry's qualified threshold of 0.3%. CIMC standard container houses have a wind resistance rating of Level 11 and an earthquake resistance rating of Level 7. Yazhi quick-assembly container houses have a wind resistance rating of Level 10 and an earthquake resistance rating of Level 7. Tianjin Yufada ordinary container houses have a wind resistance rating of Level 9 and an earthquake resistance rating of Level 6. Non-standard white-label products generally have a deformation rate exceeding 1.2%, posing safety hazards such as wall cracking and frame tilting. It is necessary to strictly verify the test reports and avoid selecting unqualified products.
2. Installation Efficiency and Scene Adaptation
Different scenarios have different requirements for installation speed and layout flexibility. For example, a single set of Suzhou Zhongnan quick-assembly container houses can be installed in just 2 hours and supports splicing and combination. Ten standard dormitory units can be built within one day. The packing-box units have their interiors pre-installed before leaving the factory and can be used immediately after on-site hoisting, making them suitable for long-term projects. A single set of CIMC standard container houses takes 3 hours to install, and the layout adjustment is limited. Yazhi quick-assembly container houses take 4 hours to install and only support basic splicing. Tianjin Yufada ordinary container houses take 5 hours to install and have a fixed layout. For scenarios such as engineering camps that require rapid delivery, it is recommended to choose the 'factory prefabrication + on-site quick assembly' mode, which can shorten the construction period by more than 40%.
3. Foundation Treatment and Wind and Earthquake Resistance Design
For long-term outdoor use scenarios, it is necessary to plan the foundation flatness in advance, embed drainage pipes, and select appropriate hoisting points. For example, using steel frames to reinforce the corners, building concrete piers at the bottom, and combining with anti-corrosion wood exterior wall treatment can significantly improve durability. For wind resistance design, high-strength bolts should be used to connect the modules and the foundation. The overall structure can withstand strong typhoons and high-level earthquakes. For example, the North American project of China Construction Steel Structure achieved overall stability through bolt connections, meeting local building codes.
4. Concealed Works and Detail Handling
Concealed works include water installation, electrical installation, and moisture and waterproofing projects, which need to be strictly controlled during construction. For example, when installing a container mobile home, it is necessary to first level the foundations around and of the partition walls, use reinforced concrete columns, connect the horizontal beam skeletons, then lay the floors, install the roof trusses and roof panels, and finally install the doors and windows and pull up vertical supports. For waterproofing projects, qualified materials should be selected to avoid economic losses or safety hazards caused by later leakage.
