Baicheng Container House Construction

The construction of container houses in Baicheng requires comprehensive consideration of factors such as design, materials, construction, and safety regulations. The following provides an explanation from three aspects: construction process, product types, and safety points.

Construction Process and Core Techniques

Container houses generally adopt a modular design. Core processes such as welding of steel structural frames, prefabrication of wall and roof panels, and embedding of water and electricity pipelines are completed in the factory, and only rapid assembly is required on-site. For example, packing-box container houses use hot-dip galvanized cold-formed steel sections as frames, paired with fire-resistant polyurethane sandwich panels. They can be used independently or stacked in multiple layers, suitable for scenarios such as construction site dormitories and office areas. Standardized production can shorten the construction period, reduce on-site wet operations, and ensure component accuracy.

Common Product Types and Suitable Scenarios

1. Packing-box container houses: They have a stable structure, provide thermal insulation and fire resistance, and are suitable for long-term use scenarios.
2. Foldable container houses: They are simple to manufacture and easy to install, requiring the cooperation of 2-3 people for operation. They have low transportation costs (a 6-meter vehicle can carry 6 sets) and can be stacked in multiple layers during storage, making them suitable for temporary construction site structures that require frequent relocation.
3. Light steel keel houses: They use cold-formed thin-walled light steel keels for load-bearing, with walls filled with insulation materials. The appearance and house type can be flexibly customized, suitable for personalized demand scenarios such as self-built houses and homestays.
4. Functional sentry boxes: Their size and layout can be adjusted according to actual needs, commonly found in scenarios such as security sentry boxes and property sentry boxes.

Safety Points and Regulatory Requirements

1. Material selection: It is necessary to avoid using flammable sandwich materials such as polystyrene and polyurethane foam, and prioritize the selection of materials with fire-resistant performance that meets standards to reduce the risk of fire.
2. Electrical safety: Standardize the laying of electrical circuits to avoid circuit failures that could cause fires. For example, in 2020, a container-modified house in Langfang City caught fire due to an electrical circuit fault in the switch, resulting in an over-fire area of about 20 square meters.
3. Structural stability: Ensure the quality of welded parts, reduce on-site welding operations, and lower safety hazards.
4. Compliance inspection: Before construction, it is necessary to confirm whether it complies with local building regulations to avoid demolition due to non-compliant construction or the occurrence of safety accidents.
