Container House Design Specifications

Container house design specifications cover design principles, material selection, structural design, seismic design, and other related requirements, as detailed below:

I. Design Principles
Container house design must balance structural stability, space utilization, environmental adaptability, safety, and seismic resistance. Structural stability requires retaining original load-bearing components during renovation to avoid disrupting overall balance through window or door openings or cutting. Space utilization should be achieved through efficient layout and multifunctional furniture. Environmental adaptability should consider insulation, heat preservation, and ventilation to ensure a comfortable interior environment. Safety must comply with fire prevention and electrical shock protection standards. Seismic design should follow the principle of 'prevention first, seismic resistance secondary,' planning based on geological conditions, seismic activity, and climatic conditions.

II. Material Selection

1. Structural Materials: High-quality container materials should be prioritized, with high-strength, corrosion-resistant connectors and fasteners. The outer shell should retain weathering steel, with internal rock wool or polyurethane foam insulation layers. Steel should comply with standards such as 'Weathering Structural Steel' GB/T 4171, and corner fittings should meet 'Series 1 Container Corner Fittings' GB/T 1835.
2. Interior Decoration Materials: Walls and floors should use bamboo, wood, or recycled wood, with lightweight gypsum board ceilings.
3. Door and Window Materials: Aluminum alloy or UPVC frames paired with double-glazed windows enhance sealing and insulation.
4. Furniture Materials: Lightweight yet sturdy materials like composite boards or metal frames, with smooth surfaces and no sharp edges.

III. Structural Design Requirements
Compliance with standards such as the 'Unified Standard for Reliability Design of Engineering Structures' GB 50153 is essential, ensuring load calculations, structural calculations, and construction meet standards. Box panel wall openings should be staggered, with overhanging sections kept short and unperforated. Connection nodes should facilitate installation, with non-load-bearing panels requiring reinforcement verification. Fire prevention and corrosion resistance measures should be clearly outlined in design documents. Existing containers should meet inspection standards outlined in 'Technical Requirements for Repair of Steel General-Purpose Containers' GB/T 12418.

IV. Seismic Design Points
Foundations must be robust and reliable, with structural designs adopting a dispersed load concept. Connectors should be professionally fastened, with key areas reinforced, such as adding supports or strengthening plates.

V. Other Design Requirements
These include spatial planning, environmental protection, craftsmanship, electrical layout, and cost-effectiveness. For example, spatial planning should clarify functional zoning and flow design; electrical layouts are recommended to be customized by professional manufacturers; cost-effectiveness can be achieved by increasing bed capacity to reduce costs.

VI. Seismic Performance Evaluation and Construction Acceptance
An evaluation system should be established, with quantified standards developed, regular monitoring and maintenance conducted, and strict construction management and acceptance procedures enforced to ensure construction quality meets specifications.
