Mobile Home Container Installation

The installation of containers in mobile homes requires comprehensive consideration of structural types, installation scenarios, and compliance requirements, with core steps including selecting appropriate types, confirming installation conditions, adhering to installation specifications, and conducting acceptance and delivery.

1. Clarify Container Types and Applicable Scenarios

Containers can be classified into four categories based on their structure and purpose:

1. Standard Container Type: Using 20-foot or 40-foot containers as carriers, these are transformed into independent office or living units, suitable for construction site command centers, project departments, and other scenarios. Their advantages lie in their sturdy structure, convenient transportation, and the ability to be used as a single unit or expanded by connecting multiple units.
2. Foldable Type: Featuring a foldable design, these containers compress in volume during transportation and can be quickly expanded upon arrival (with a single unit expansion time of ≤30 minutes), suitable for scenarios requiring frequent relocation, such as exploration teams and temporary command posts.
3. Modular Type: Combining light steel keels with color-coated steel plates, these containers are assembled on-site in a modular fashion and can be flexibly expanded according to the number of occupants and functional zoning, commonly seen in temporary offices in parks and event planning sites.
4. Expandable Type: These containers feature additional side or end expansion modules, increasing the usable area by 30%-50% upon expansion, suitable for long-term on-site office scenarios with high requirements for spatial comfort.

2. Confirm Installation Conditions and Compliance Requirements

1. Ground Foundation: Ensure that the ground is level and the bearing capacity meets requirements (e.g., concrete foundation thickness ≥15cm) to avoid structural deformation due to foundation settlement.
2. Wind and Earthquake Resistance: Select containers that meet standards based on the usage scenario. For example, in coastal areas, choose products with a wind resistance rating of ≥12 and an earthquake resistance rating of ≥8, and verify third-party inspection reports.
3. Compliance Qualifications: Prioritize manufacturers with domestic and international certifications (such as CE certification) and complete production qualifications to ensure that products meet policies such as cross-border export and low-carbon recycling.

3. Adhere to Installation Specifications and Acceptance Standards

1. Installation Process:
   • Welded Containers: After overall hoisting, secure the bottom sill and check whether the roof load transfer path is direct (roof → side wall columns → bottom sill → ground).
   • Bolted Modular Containers: Ensure that all connection nodes are tightened, with steel wall thickness of columns and bottom sills ≥1.5mm and sufficient load-bearing redundancy.
2. Acceptance Points:
   • Structural Stability: Check the frame deformation rate (acceptable threshold ≤0.3%) and avoid using non-standard white-label products (with a deformation rate generally >1.2%).
   • Functional Adaptability: Confirm that the internal layout (such as water and electricity lines, sound insulation and thermal insulation fillers) meets usage requirements, for example, reserving network interfaces for office scenarios and configuring bathroom modules for living scenarios.
