Container House Roof Making

The making of a container house roof requires consideration of structural type, material selection, and process requirements, with core steps including frame construction, roof panel installation, and waterproofing treatment. Details are as follows:

I. Frame Construction and Structural Stability

The roof of a container house relies on a sturdy steel frame. Common structures include welded integral containers and bolt-connected modular containers:

• Welded Integral Containers: These are fully welded in the factory, with roof loads transferred through sidewall columns to the bottom sill, and then evenly distributed to the ground. They have strong resistance to deformation and are suitable for scenarios requiring frequent lifting and movement.
• Bolt-Connected Modular Containers: These use standard panels connected by bolts. It is essential to check the wall thickness of the steel used for columns and bottom sills (common specifications range from 1.5 to 3 millimeters). Thicker walls provide greater load-bearing redundancy but increase self-weight. The tightness of connection nodes directly affects overall stability, so it is crucial to ensure bolts are not loose.

II. Roof Panel Materials and Installation Process

Roof panels must balance thermal insulation, fire resistance, and waterproofing:

• Material Selection: Commonly used materials include rock wool, glass wool, or polyurethane sandwich panels, typically 50 millimeters thick, offering both thermal insulation and fire resistance. The outer layer can be made of weather-resistant steel (1.2-3.0 millimeters thick) or galvanized steel sheet roll-formed, while the inner decorative layer often consists of bamboo-wood fiberboard, wood veneer, or gypsum board.
• Installation Points: Roof panel joints should use waterproof adhesive (such as glass curtain wall waterproof adhesive) to prevent degradation of waterproofing performance due to wind and rain exposure with ordinary adhesives. Joints must be sealed with adhesive to prevent leakage.

III. Waterproofing and Sealing Treatment

Roof waterproofing is a critical aspect:

• Roof Panel Waterproofing: Joints between roof panels should be coated with waterproof adhesive, ensuring a uniform layer that covers all gaps.
• Edge Treatment: Eaves, gutters, and other edge areas should be fitted with waterproof barriers tightly connected to the roof panels to prevent rainwater backflow.
• Drainage System: Design a reasonable drainage slope (generally ≥2%) to ensure rapid drainage of rainwater and prevent water accumulation.

IV. Process Performance Optimization

• Weld-Free Quick Installation Process: Using bolts or rivets for connections reduces on-site welding operations, lowering construction difficulty and safety risks while facilitating disassembly and relocation.
• Disassembly and Wear Control: Select wear-resistant and corrosion-resistant materials to minimize structural wear after multiple disassemblies. Leading manufacturers' products can typically be reused up to 8 times or more, reducing construction waste emissions by approximately 90%.
