Container House Construction Standards

Container house construction standards cover multiple aspects such as design, construction, and acceptance, and must comply with national and industry regulations to ensure safety, applicability, and economic rationality.

I. Basic Design Regulations

Container house design should adhere to the principle of modular coordination, utilizing standardized dimensions (e.g., international standard 20-foot containers measuring 6.058 meters in length, 2.438 meters in width, and 2.591 meters in height, with a load capacity of 25 tons; 40-foot containers measuring 12.192 meters in length, 2.438 meters in width, and 2.591 meters in height, with a load capacity of 45 tons). Space expansion is achieved through container combinations. The design should meet indoor environmental requirements, including ventilation, lighting, and sound insulation, and be equipped with a comprehensive building equipment system (e.g., water and electricity, heating, ventilation, and air conditioning). Environmental protection and energy-saving design should comply with current standards, such as using color-coated steel composite panels filled with fire-resistant rock wool for both thermal insulation and sound insulation.

II. Structural and Material Standards

The structural system primarily consists of steel frames, with the thickness of main beams and columns meeting load-bearing requirements. Welding should be full and free of cold welds, and containers should undergo overall galvanization or anti-corrosion coating. Structural calculations should consider container strength, stiffness, and reinforcement of openings, with seismic performance meeting an 8-degree fortification requirement. Modular design should support independent use of a single container or combination of multiple containers, with connection nodes featuring waterproofing capabilities to ensure stability during stacking or side-by-side arrangement.

III. Construction and Acceptance Specifications

The construction process should be quality-controlled with reference to BIM models, with key processes (e.g., container assembly, foundation treatment) confirmed by on-site supervisors. Acceptance is divided into three parts: materials, factory production, and on-site installation. Materials should be inspected for certificates of conformity for steel and accessories; factory production should check container dimensional deviations and welding quality; on-site installation should verify structural stability, waterproofing performance, and pipeline connections. The acceptance criteria for inspection lots are 100% compliance for main control items, a pass rate of ≥80% for general items, and no serious defects.

IV. Fire Protection and Anti-Corrosion Requirements

Building fire protection should comply with the "Code for Fire Protection Design of Buildings," using fire-resistant rock wool to fill walls and setting up fire compartments and evacuation routes. Anti-corrosion treatment should involve galvanizing or coating steel structures, with enhanced measures in coastal or high-humidity areas. Special-function containers (e.g., high-altitude workstations) should be equipped with additional thermal insulation layers or fire-resistant materials to meet extreme climate requirements.
