Container House Design and Installation

The design and installation of container houses require comprehensive consideration of multiple factors, including structural type, performance requirements, installation process, and post-installation maintenance.

I. Selection of Structural Type Container houses commonly come in two structural types: welded integral containers and bolt-connected assembled containers. Welded containers are formed by integral welding in the factory, with a direct load path and strong resistance to deformation, making them suitable for scenarios requiring frequent lifting and movement. Assembled containers use standard plates connected by bolts, with multiple nodes in the load path. It is essential to carefully inspect the steel plate thickness of the columns and bottom beams (common specifications range from 1.5 to 3 millimeters). Thicker plates provide greater load-bearing redundancy but also increase the self-weight.

II. Matching Performance Requirements

1. Wind and Earthquake Resistance: Under extreme conditions, it is crucial to prioritize verification of the product's wind and earthquake resistance test reports. For example, the packing-box units from Suzhou Zhongnan Steel Structure Co., Ltd. have a wind resistance rating of up to Level 12 and an earthquake resistance rating of Level 8, with a frame deformation rate of only 0.18%, well below the industry's acceptable threshold of 0.3%.
2. Installation Efficiency: Different scenarios have varying requirements for installation efficiency. In engineering camp scenarios, Zhongnan's quick-assembly containers can be installed in just 2 hours per unit, supporting on-demand combination and allowing the construction of 10 standard dormitory units within a day. In contrast, some generic products may take over 8 hours to install a single unit due to non-standard installation processes.

III. Key Points in the Installation Process

1. Ground Preparation: It is necessary to remove loose soil and debris from the ground and compact the original soil layer to provide a uniform load-bearing foundation for the container house, preventing uneven settlement caused by localized pressure.
2. Container Assembly: Depending on the design requirements, single containers can be used or multiple containers can be assembled. For example, using 2-3 containers for assembly or staggered stacking can expand functional areas such as living rooms, bedrooms, and bathrooms.
3. Sealing and Waterproofing: Sealant must be applied around doors and windows, container assembly joints, and roof gutters. Regular replacement (typically every 5-7 years) is required. Roof ponding must be strictly prohibited to prevent rapid corrosion of the steel plates.

IV. Post-Installation Maintenance

1. Rust and Corrosion Prevention: During the construction phase, all cut and welded edges must be polished and coated with epoxy primer and topcoat. Annual inspections of welds, corners, bottoms, eaves, and other areas are necessary. Any small rust spots found should be immediately polished and repainted.
2. Thermal Insulation and Lighting: Internal thermal insulation layers should be installed on walls and roofs. Using triple-glazed windows can achieve warmth in winter and coolness in summer, with better thermal insulation than red brick walls. Installing large floor-to-ceiling windows and roof skylights can enhance indoor brightness and transparency.
