Container House Construction Flowchart

The construction process of container houses is mainly divided into four stages: preliminary preparation, overall structural construction, functional enhancement and decoration, and post-construction maintenance:

I. Preliminary Preparation

1. Land Approval: Approval procedures must be completed based on the land nature. For rural homesteads, structural drawings stamped by an engineer are required; construction on cultivated land and basic farmland is prohibited; approval from the forestry department is needed for forest land; leased land is mostly for temporary structures, and the contract must specify the nature of use.
2. Foundation Construction: Select the foundation type (such as pile foundation, large slab foundation, or strip foundation) based on the seismic fortification intensity, and construct it in combination with the geological conditions and building load to ensure foundation stability.

II. Overall Structural Construction

1. Setting Out and Ground Beam Installation: Mark the positions according to the drawing dimensions and use a level tube to mark the elevation points; after the ground beams are hoisted, correct their positions (deviation ≤ 3mm) and elevations, adjusting them based on the highest point.
2. Column and Floor Installation: After the columns are erected, they are welded into shape; the floor slab must be laid with mortar, and slabs with cracks are prohibited; the surface must be densely compacted and polished.
3. Wall and Container Assembly: Install the walls according to the layout drawing, and seal the corners with angle aluminum; expand the functional areas (such as living-dining rooms, bedrooms, and bathrooms) by assembling 2-3 containers or stacking them in a staggered manner; the staggered design can improve ventilation and lighting.

III. Functional Enhancement and Decoration

1. Lighting and Insulation: Install large floor-to-ceiling windows, skylights, or glass partitions to enhance lighting; install internal insulation layers on the walls/roof, select triple-glazed windows, and set up eaves or sunshades to prevent sun exposure.
2. Internal Decoration: Install wooden frame partitions and insulation layers, and install doors, windows, lights, and facilities (such as real fireplaces) according to the design; reserve spaces for wires and switches, and construct internal and external insulation on the exterior walls simultaneously; use gypsum board with light steel keels for the ceiling and walls, and install external insulation on the roof after cleaning.

IV. Post-Construction Maintenance

1. Rust Prevention and Corrosion Protection: Grind and apply epoxy primer + topcoat on the cut and welded edges; regularly inspect welds, corners, and other parts, and immediately repaint any rust spots found; repaint with anti-corrosion paint regularly according to the environmental humidity (inland: 8-12 years; southern region: 7-10 years; coastal region: 3-5 years).
2. Waterproofing and Sealing: Replace the sealant for doors, windows, assembly joints, and gutters every 5-7 years; clean the roof leaves annually to avoid water accumulation.
