Container House Technical Specification
The Container House Technical Specification mainly revolves around standards such as CECS 334:2013 'Technical Specification for Modular Container Houses', JGJ/T 469-2019 'Technical Specification for Container-Type Combined Houses', and GB/T 51329-2018 'Technical Standard for Modular Container Buildings'. The following are the key points:
Scope of Application and Basic Requirements: The specification applies to the design, construction, and acceptance of low-rise and multi-story modular container house projects. The number of floors should not exceed 6, the height should not exceed 24 meters, and the seismic fortification intensity should not exceed 8 degrees. The design service life is determined based on the structural importance coefficient, generally being 50 years or 25 years. Existing containers must be inspected and qualified, with no defects in beams and columns, and all 8 corner fittings must be intact and reliable. Quality certification documents are required upon arrival at the site.
Structural Load-Bearing and Construction: The house adopts a pure steel frame load-bearing system, with wall panels, roof panels, glass, etc., not bearing loads. The load path is transmitted through panel secondary beams, main beams, corner columns, and corner fittings to the foundation or lower container. Corner fittings are the only stacking load-transfer points and cannot be replaced with spot welding. Welding weathering steel should be used for container bodies, while non-container components can use Q235B or Q345B. When large openings weaken the stiffness, perforated and non-perforated containers should be arranged in a staggered and symmetrical manner. The overhanging length should not be too large, and no openings are allowed in the overhanging sections. Lateral force-resisting members should be symmetrical in plan and have uniform vertical stiffness. When stacking multiple containers, corner fittings and corner columns must be aligned and locked vertically.
Fire Protection and Corrosion Prevention: Prohibited filling materials for enclosures include EPS and other flammable core materials. For crowded places, A-grade rock wool or glass wool should be selected, and the fire resistance limit should meet the requirements of GB50016. Steel structures should be painted with fire-resistant coatings, floor fire separations should be set up, and escape routes, fire extinguishers, smoke detectors, emergency lighting, and other facilities should be provided.
