Dali Container House Construction

The construction of container houses in Dali requires comprehensive consideration of various factors such as design, materials, construction, and compliance.

I. Design Planning
The design of container houses should be flexibly adjusted according to the usage scenario. For example, homestays or rural courtyards can use 2-3 containers spliced together to form functional areas such as living and dining rooms, bedrooms, and bathrooms, with staggered floor designs to increase spatial hierarchy. Construction site activity rooms should focus on robustness, durability, and ease of assembly and disassembly. During the design process, it is necessary to reserve positions for doors and windows and consider the pre-embedding of internal water and electricity pipelines and the laying of sound insulation and thermal insulation layers to ensure that the containers can be directly spliced for use after leaving the factory.

II. Material Selection
Materials directly affect the performance and cost of the house. Container houses made of rock wool insulation boards are the mainstream choice for construction site dormitories and other scenarios due to their comfortable living conditions and high safety. Ordinary insulation foam board materials are lower in price but slightly inferior in performance. The exterior facade materials can be selected from anti-corrosion wood, glass curtain walls, or themed murals to break away from the industrial feel. The roof needs to be equipped with eaves or sunshades to prevent exposure to the sun in summer.

III. Construction Key Points
Construction should follow standardized procedures: independent pile foundations should be used for the foundation to prevent moisture and insects. During container splicing, ensure that welds are ground, and epoxy primer and topcoat are applied to prevent rust. Sealant around doors and windows and at splicing joints should be regularly replaced to prevent water leakage. The construction period is more than 50% shorter than that of traditional brick-and-mortar houses and is not affected by the rainy season.

IV. Compliance Requirements
If construction is carried out on rural homesteads, building approval must be obtained, and structural drawings must be submitted to avoid being identified as illegal construction. Construction on cultivated land and basic farmland is strictly prohibited, and forestry approval is required for forest land. Leased land can only be used for temporary buildings. Container houses belong to steel structure buildings and must comply with local building codes and cannot be built arbitrarily.

V. Post-construction Maintenance
The core of maintenance is rust prevention and waterproofing. Check welds, corners, and other parts annually, and immediately repaint any rust spots found. In inland areas, anti-corrosion paint needs to be reapplied every 8-12 years, in southern humid areas every 7-10 years, and in coastal areas every 3-5 years. The container should be installed on supports to avoid direct contact with ground moisture.
