Construction Specifications for Container Houses

The construction specifications for container houses cover various aspects such as design, materials, construction, acceptance, and safety and environmental protection. It is essential to strictly adhere to national and industry standards to ensure project quality and safety.

I. Design Specifications
The design of container houses must comply with standards such as the "Technical Standard for Modular Combined Container Houses" (CECS334-2012) and the "Code for Acceptance of Construction Quality of Steel Structures" (GB50205-2020). The design should specify parameters such as structural form (e.g., light steel frame with rock wool sandwich panels), seismic fortification intensity (≤8 degrees), fire resistance rating (Grade II), and service life (typically 5 years, up to 50 years in special scenarios). Modular design should consider modular coordination, spatial combination forms (single container, combined containers, stacked containers, etc.), and functional uses (accommodation, office, commercial, etc.) to ensure reasonable structural loading, clear load transfer paths through corner fittings, and avoidance of weakening stiffness by opening holes in cantilevered sections.

II. Material Specifications
Materials must meet fire prevention, corrosion resistance, and environmental protection requirements. Steel structures should use welded weathering steel (GB/T 4171) or Q235B/Q345B (GB/T 700, GB/T 1591). For enclosure and filling, the use of flammable core materials such as EPS is prohibited, and A-grade rock wool/glass wool should be used in crowded places. Wall and roof materials should have sound insulation, thermal insulation, and waterproofing functions, while doors and windows should have good sealing and flexible opening. Foundation materials (concrete, steel bars) must comply with standards such as the "Code for Acceptance of Construction Quality of Building Water Supply and Drainage and Heating Engineering" (GB50242-2002).

III. Construction Specifications
Construction should follow standards such as the "Technical Code for Safety in Construction Lifting and Hoisting Engineering" (JGJ276-2012), with a focus on controlling the verticality of stacked containers, seismic resistance and loosening prevention of node connections, and waterproof sealing quality. Foundation construction should be stable and firm, using concrete foundations. Wall, roof, and door/window installations should meet design requirements to ensure complete functionality. Interior decoration should be carried out according to customer needs, with environmentally friendly materials. During construction, strict measurement and setting-out accuracy should be maintained, and lifting operation safety management should be strengthened, adhering to the principle of "safety first, quality first."

IV. Acceptance Specifications
Acceptance should refer to the "Acceptance Standard for Construction Quality of Container Houses," covering material quality, factory production quality, and on-site project quality. Acceptance should inspect component qualification marks, sampling inspection results of main control items and general items, and ensure that the quality pass rate meets standards. Qualified components should be marked as such and comply with quality management system requirements.

V. Safety and Environmental Protection Specifications
A sound safety management system should be established during construction, with strengthened on-site safety management and regular safety inspections. Environmental protection measures should reduce dust pollution and comply with civilized construction requirements. For temporary buildings, container-type movable panel houses should be prioritized, with a combustion performance rating of Grade A. Installation and dismantling should be carried out by professional teams.
