Panjin Container Structure House
The Panjin container structure house takes a standard steel structure frame as its core, adopts a modular design, and has characteristics such as rapid assembly, pressure resistance, wind resistance, and corrosion resistance. The walls are filled with insulation materials, balancing lightweight and thermal insulation properties, making it suitable for scenarios like temporary offices, wild field stations, and emergency housing.
Structural Principles and Material Characteristics
Container structure houses originate from the design of freight containers. The main body uses a hot-dip galvanized cold-formed steel frame, which forms a stable structure through welding or bolt connections, possessing pressure-resistant, wind-resistant, and corrosion-resistant properties. The walls typically use color-steel sandwich panels (filled with materials such as rock wool, glass wool, or polyurethane), with insulation materials in the middle. They are covered with metal sheets or calcium silicate boards, balancing lightweight and thermal insulation and fire-resistant properties. The floors often use cement fiber boards or steel-wood composite floors, with doors, windows, and electrical systems pre-installed to ensure rapid commissioning.
Modular Design and Assembly Advantages
Its core is the concept of a "movable building," achieving rapid assembly and disassembly through standardized modular design. The steel structure frames, wall panels, roof panels, and internal pipelines are prefabricated in the factory, and only hoisting and splicing are required on-site, significantly shortening the construction period. For example, after the foundation of a 6-meter-long container house is leveled, it can be hoisted into place and powered on for occupancy. Two to three people can cooperate to complete the installation. A 17.5-meter flatbed truck can transport 20 sets of folding containers, which can be stacked in multiple layers during storage, reducing transportation and storage costs.
Adaptability and Application Scenarios
Container houses have a stable structure and can withstand extreme weather conditions such as typhoons and earthquakes. They do not occupy permanent building quotas and have high flexibility. Common products include:
- Packing-box units: Used independently or stacked and combined, suitable for construction site dormitories and office areas;
- Light steel frame houses: Customizable in appearance and layout, suitable for homestays and scenic area facilities;
- Functional kiosks: Such as security kiosks and environmental protection public toilets, with flexible size adjustments.
Manufacturing Process and Quality Control
Manufacturers complete steel cutting, welding, surface treatment, and wall panel composite processing through standardized production lines, and conduct trial assembly before leaving the factory to ensure component matching. Key processes include:
- Steel structure processing: Using Q235B galvanized square tubes, determining cross-sectional dimensions through mechanical simulation calculations, and completing node fusion welding with high-frequency welding machines;
- Wall panel compositing: Filling with fire-resistant polyurethane or rock wool, covering with metal sheets, and then pressing and pressure testing with sealing strips;
- On-site installation: Modules are hoisted into place and spliced, reducing wet operations and ensuring component accuracy.
Cost and Environmental Advantages
Compared with traditional color-steel houses, container houses have lower costs throughout the production, transportation, storage, and use cycles and can be folded repeatedly more than 500 times. Their recycling meets emergency housing standards. Some designs incorporate environmental protection concepts, such as solar power supply and the use of recyclable materials (containers and pallets), reducing dependence on external power grids.
