Office Container House Installation

The installation of office container houses should adhere to technical specifications such as structural mechanics, ground engineering, and waterproofing. The core process includes selection, ground treatment, lifting and positioning, structural connection, and water and electricity installation. The specific steps are as follows:

1. Selection Stage: Clarify Structural Type and Material Standards

Container houses are divided into two types: welded integral containers and bolt-connected assembled containers. Welded containers are formed as a whole in the factory, with loads transferred from the side wall columns to the bottom sills and then evenly distributed to the ground, offering strong resistance to deformation and being suitable for frequent lifting scenarios. Bolt-connected assembled containers use standard panels for assembly, and it is essential to focus on inspecting the wall thickness of the columns and bottom sills (common specifications range from 1.5 to 3 millimeters) and the coating process. Hot-dip galvanizing treatment significantly outperforms cold-dip galvanizing in terms of corrosion resistance and is particularly suitable for regions with large diurnal temperature variations and significant humidity changes.

2. Ground Treatment: Ensure Uniform Load-Bearing Capacity

The bottom sills of container houses are typically I-beams or channel steels, with limited contact area with the ground. 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 frozen soil layer. The horizontal error of the foundation top surface should be controlled within 5 millimeters. For short-term use scenarios, precast concrete blocks or steel plates can be used, with a spacing between blocks not exceeding 2 meters and a crushed stone leveling layer laid underneath. The floating soil and debris on the ground should be thoroughly cleared, as the compaction degree of the original soil layer directly affects the stability of the container.

3. Lifting and Positioning: Control Contact Status and Levelness

Containers typically have 4-6 lifting points at the bottom, and steel wires with matching load-bearing capacity should be used to ensure synchronous force application at all lifting points. After the container is positioned, immediately check the fit between the bottom sill and the foundation blocks, and use thin steel sheets to pad any local suspended areas to avoid floor vibration or abnormal noise during subsequent use. Levelness detection should be carried out separately along the longitudinal and transverse directions of the bottom sill, with an error controlled within 2 millimeters per meter. This step is crucial for controlling the verticality of multi-layer stacked structures.

4. Structural Connection: Enhance Seismic Resistance and Anti-Loosening Performance

When stacking multiple containers, the vertical deviation should be monitored in real-time using a laser level. High-strength bolts should be used at the node connection points and anti-loosening adhesive should be applied. Waterproof sealing work should focus on the joints between containers, using weather-resistant silicone sealant with a lap width of not less than 2 centimeters. For regions with a seismic fortification intensity of 7 degrees or higher, steel frames should be added at the structural corners for reinforcement, and the height of the concrete piers at the bottom should be not less than 30 centimeters.

5. Water and Electricity Installation: Reserve Space for System Expansion

The internal pipelines should adopt a modular design, with dedicated air conditioning sockets (16A) and ordinary sockets (10A) reserved in the electrical circuit. The diameter of the water supply pipes should be determined based on the number of users (it is recommended to be DN25 or above). The drainage system should be equipped with a diversion trough with a slope of not less than 2%, and the floor drain diameter should be not less than 75 millimeters. All pipeline penetrations through walls should be sealed with fire-resistant rock wool, and the external power supply should be equipped with a leakage protection device, with a grounding resistance value of not more than 4 ohms.
