Self-made Welded Container House
To build a self-made welded container house, it is essential to master key steps such as material selection, structural design, welding techniques, and assembly processes, as detailed below:
Material Selection and Preparation
The framework materials for container houses must possess high strength and corrosion resistance. The main crossbeams around the chassis typically use 140×50 channel steel, with the spacing between crossbeams controlled within 35 centimeters to enhance chassis stability. For columns and roof ring beams, it is recommended to use 5×5×2.0 square steel, connected through full-weld techniques to ensure structural integrity. Side and roof panel materials should be selected based on cost and requirements. Standard side panels for shipping containers are 1.6mm thick, while roof panels are 2.0mm thick, though custom panels ranging from 1.0-2.0mm can also be ordered. Additionally, decorative materials such as fire-resistant flooring, wooden flooring, doors, windows, and ceiling panels, as well as basic components like channel steel, square tubes, and corrugated sheets, should be prepared.
Structural Design Considerations
The house structure must adhere to mechanical principles to ensure load-bearing and wind-resistance capabilities. The chassis crossbeams should be welded using 4×8×2.0 square steel, forming a grid-like support system. Column thickness should not be less than 1mm, and they should be shaped using professional equipment or purchased as finished products. Roof design should consider drainage and load-bearing, with a recommended四面圈梁 (four-sided ring beam) structure forming a closed frame with the columns. If expanding the space, multiple containers can be combined and spliced, but connection nodes should be planned in advance to ensure structural stability.
Welding Techniques and Quality Control
Welding is the core process in constructing container houses and must strictly follow operational standards. The connection between the chassis and columns should employ full-weld techniques to prevent structural loosening due to weld defects. The welding between the roof ring beams and columns must ensure perpendicularity, with an error margin controlled within 2mm. Protective equipment should be used during welding to prevent safety hazards caused by metal splatter. After welding, the welds should be ground to remove burrs and sharp edges, preventing damage during the installation of decorative materials later.
Assembly and Decoration Process
After the basic structure is welded, box assembly and interior decoration should be carried out. First, install the side and roof panels, securing them with bolts or rivets to ensure airtightness. Next, lay the flooring and ceiling, choosing fire-resistant or wooden materials based on requirements. Finally, install the doors, windows, and electrical systems, with doors and windows requiring pre-drilled installation holes and electrical systems needing pre-planned wiring to avoid damaging the structure with later trenching. During the decoration phase, paint colors and furniture styles can be chosen according to personal preferences, but attention should be paid to material environmental friendliness to avoid excessive formaldehyde levels.
