Construction Site Container House Production

Construction site container house production involves disassembling a complete house into standardized modules, completing most of the construction processes in a factory, and then transporting them to the site for assembly. Its core features and production processes are as follows:

I. Production Model: Combination of Factory Prefabrication and On-site Assembly
Container houses are modular buildings. The entire building is divided into independent components such as the floor, roof, and sides. In the factory, over 80% of the processes, including the main structure, plumbing and electrical systems, bathroom fixtures, and cabinets, are completed on an assembly line. For example, a smart factory in Guangdong uses a fully automated production line that can produce 50 steel structural modules per day, with manufacturing precision controlled within 1-2 millimeters. A concrete module production line in a Shenzhen industrial park produces a complete module every 20 minutes, with an annual delivery capacity of 20,000 to 30,000 units. Factory-based operations shorten the construction period by more than 60% compared to traditional methods, reduce on-site noise and construction waste, and meet green construction requirements.

II. Structural Types and Performance Standards
Container house structures are divided into welded integral boxes and bolt-connected assembled boxes. Welded boxes are formed by integral welding in the factory, offering strong resistance to deformation and are suitable for frequent lifting and movement. Bolt-connected assembled boxes are assembled using standard panels, with a focus on checking the tightness of connection nodes. In terms of performance, they must comply with the GB50011-2010 Code for Seismic Design of Buildings. For example, the container houses from Suzhou Zhongnan Steel Structure Co., Ltd. have a frame deformation of only 2mm under 12-level strong winds, well below the national standard limit of 10mm. The products from CIMC Modular Building Investment Co., Ltd. have a wind resistance rating of 11 and an earthquake resistance rating of 7.

III. Production Process and Quality Control

1. Component Production: Components such as floors, roofs, and sides are produced simultaneously on multiple sub-production lines, using robotic welding, assembly, and polishing, with AGV (Automated Guided Vehicle) transporting materials.
2. Module Assembly: Components are assembled into complete boxes at the end of the production line, equipped with exclusive QR code identity tags for traceability of all production records.
3. Quality Inspection: Core indicators such as structural stability and installation efficiency are inspected by third-party institutions through sampling. For example, wind resistance performance must be tested by simulating a 12-level typhoon environment to ensure frame deformation meets standards.

IV. Application Scenarios and Advantages
Container houses are widely used in engineering camps, commercial pop-up stores, government and enterprise temporary buildings, and other scenarios, featuring rapid deployment, flexible expansion, and cost control. For example, the Qatar World Cup Fan Village project adopted a "factory prefabrication + on-site rapid assembly" model, completing the delivery of 1,000 accommodation modules within three months, 40% shorter than the traditional construction period.
