New Star Container House
The New Star Container House is manufactured by Baotou New Star Color Plate Steel Structure Manufacturing Co., Ltd., and its core materials and process features are as follows:
I. Main Structural Materials
The house uses national standard Q235 galvanized square tubes as the main steel frame, with a wall thickness of no less than 1.5 millimeters. After anti-corrosion and anti-rust treatment, its service life can reach more than 15 years. The columns are optimized for multi-layer combination requirements. The columns of ordinary containers are 4-millimeter-thick square steel, and when stacked in two layers, they are upgraded to 6-millimeter-thick square steel. Reinforcing ribs are added at the connection nodes, increasing the overall compressive strength by about 50%.
II. Enclosure Panel Configuration
The wall and roof panels are made of double-layer colored corrugated steel sheets, filled with 50-100 millimeters of rock wool or polyurethane insulation material. In response to the long winters and large day-night temperature differences in the Jining area of Inner Mongolia, the panels adopt a special coating process: the outer layer uses a high weather-resistant polyester resin coating, and the inner layer adds a moisture-proof aluminum foil layer, effectively reducing the probability of condensation and preventing moisture on the inner walls of the container.
III. Key Process Details
Air Tightness Control
The joints between the door frame and the container body use ethylene propylene diene monomer rubber seals, which have better weather resistance than ordinary silicone seals and a service life of more than 5 years. During production, CNC bending machines are used to control the bending angle of the door frame within ±0.5 degrees, and the glue application at the joints is uniform and continuous, ensuring the precision of mechanized construction.Water and Electricity Integration Design
The embedded pipelines are integrated into the chassis of the container, adopting a quick-connector design. On-site construction does not require additional trenching, reducing installation errors. Standardized water and electricity interfaces support quick connection when multiple containers are combined.Modular Structure Optimization
To meet the needs of multi-story office areas, horizontal support beams are added to the chassis of the container to solve structural mechanics problems during vertical stacking. The standard container size is 3 meters × 6 meters, with a nominal outer diameter of 6000 millimeters and an inner diameter of 5.8 meters × 2.8 meters, supporting two or three-layer combinations.
IV. Performance Parameters
The house has wind, earthquake, and rain resistance functions, with a thermal conductivity of 20-30W/(m·K), a linear expansion coefficient of 201/K, and a longitudinal shrinkage rate of 6%-10%. The outer steel plate wall is corrosion-resistant, acid-resistant, does not rust or crack, and has a designed service life of more than 20 years.
