Container House Relocation Standard

Container house relocation must adhere to standards for structural safety, connection specifications, and operational procedures, specifically meeting the following requirements:

I. Structural Safety and Relocatability Assessment Before relocation, it is necessary to confirm whether the container house is a detachable structure. If the house is fixed using welding processes, it cannot be disassembled by container units and must be relocated as a whole through lifting. If it is a non-welded structure (e.g., bolted connections), it can be disassembled and relocated in a modular fashion. For example, a packing-box unit in Xi'an explicitly requires that 'welded structures cannot be disassembled by container units,' emphasizing the critical impact of structural type on relocation methods.

II. Relocation Operational Procedure Standards

1. Pre-treatment of Water and Electrical Systems Before relocation, the house's water and electrical systems must be disconnected, and tightly connected pipelines in each room must be removed to avoid damage from pulling during relocation. For example, during the relocation of a packing-box unit in Xi'an, it is necessary to 'first disassemble the house's water and electrical systems.'
2. Removal of Container Connection Components Use professional tools to remove connecting screws between container units, following the principle of 'removing them one by one from top to bottom' to ensure structural stability. For example, during the relocation of a customized container guardhouse by Zhongye Zhichuang, it is necessary to 'disconnect the connection components before overall lifting and positioning.'
3. Modular Disassembly (Optional) If further disassembly of the container units is required, the operation must follow the sequence of 'surface color-steel panels → roof steel plates → surrounding steel columns,' ensuring that interior decorations are separated from columns and panels to avoid structural damage. For example, during the disassembly of a packing-box unit in Xi'an, it is emphasized to 'ensure that interior decorations are not attached to columns and panels.'

III. Post-relocation Safety and Compliance Requirements

1. Structural Stability Verification After relocation, it is necessary to check whether the container connection components (e.g., screws, twist locks) are securely fastened, ensuring a wind resistance rating of at least 10 and a seismic design intensity of 8 degrees (referencing the standards in the 'Southwest Regional Development Report on Modular Buildings').
2. Fire Safety Compliance Use Class A fire-resistant sandwich panels (e.g., rock wool material) to meet construction site fire safety acceptance standards. For example, Xinsheng Integrated Housing explicitly states that 'container units uniformly use Class A fire-resistant rock wool panels.'
3. Site Adaptability Adjustments If relocating to a new site, it is necessary to select foundation types based on geological conditions (e.g., screw piles must meet bearing capacity and pull-out resistance requirements) to avoid house tilting or connection cracks due to unstable foundations.
