How Container Houses Are Built
The manufacturing process of container houses mainly includes four stages: foundation treatment and material preparation, structural construction, internal equipment and insulation treatment, and other detail processing.
Foundation Treatment and Material Preparation: Some manufacturing methods use screw pile foundations, where steel piles are screwed into the ground to a stable soil layer 2 meters deep using specialized machinery. Each pile can support approximately 5 tons of weight, eliminating the need for concrete and being reversible, thus reducing damage to the ecosystem. Processed containers are also used as the primary material, with additional crossbeams added inside. The bottom and one side are cut away for easy lifting and transportation.
Structural Construction: The house can consist of two floors, with the first floor formed by connecting two containers. Horizontal steel beams are added to the bottom of the containers as load-bearing beams and supports. The top uses super-strong adhesive to bond and reinforce the gaps in the middle, requiring three layers of adhesive to prevent rain leakage. The container unit structure is welded from special steel sections into standard components, connected by bolts between containers for a stable structure. They can be used independently or combined horizontally and vertically to form spacious spaces, with a maximum of three floors stacked vertically. Floorboards are nailed onto a base plate made of poly-ink board to form a wooden frame, with glass fiber laid as base plate insulation. After covering with rough flooring, tile adhesive is applied, followed by laying flooring or tiles. When manufacturing container walls, uprights are nailed every 40 centimeters onto a resin board, with crossbars reserved for window spaces. Steel nails are used to strengthen the structural integrity, followed by spraying adhesive. Plywood is bonded beneath the container wall structure and fixed with steel nails. After manufacturing, the container walls are erected on the base plate, with the outer wall of the plywood extending beyond the base plate for coverage and sealing, then fixed to the base plate with adhesive and steel nails. The roof installation adopts a layered construction method, first laying a ceiling made of fiberboard, then covering it with a layer of plastic film barrier, installing roof joists, framing the roof structure with墩板 (assuming it means some kind of support block, if not, please replace with the correct term), and then laying electrical wires.
Internal Equipment and Insulation Treatment: Glass fiber wool is installed between the uprights to form a soundproof insulation layer, with plastic film laid as a barrier, followed by smooth wooden panels as wall panels. Windows and doors are installed; manufacturers pre-fabricate the positions of windows and doors, which are then stacked and placed like building blocks during installation. Since container houses can be cold in winter, 10cm-thick polyurethane insulation panels are added to the exterior walls. This material not only provides insulation but also has fire-resistant properties, with fire-resistant raw materials added during manufacturing by the factory.
Other Detail Processing: The manufacturing of container houses can be completed in as little as three to five days or up to a week. Modular container houses do not require secondary decoration on-site; they can be occupied immediately after being lifted and positioned. Moreover, they can be moved as a whole on-site without disassembly and reassembly, significantly reducing the cost of secondary utilization on-site.
