Activity Container House Equipment
Container house equipment mainly includes steel selection and processing equipment, enclosure structure production equipment, connection node manufacturing equipment, surface anti-corrosion treatment equipment, and modular assembly and installation equipment.
Steel Selection and Processing Equipment: The main frame of container houses often uses high-strength weather-resistant steel, such as grade Q355B, which has a yield strength approximately 30% higher than that of ordinary carbon steel. Steel processing equipment must have high-precision cutting, welding, and forming capabilities to ensure the stability and self-balancing ability of the container structure. For example, a self-balancing system is formed through rigid connections between corner fittings and side beams, reducing the need for additional reinforcement components.
Enclosure Structure Production Equipment: Enclosure structures typically adopt a composite construction, such as a three-layer composite panel consisting of "rock wool-air layer-aluminum-zinc coated steel plate." Production equipment must precisely control the thickness of the rock wool layer (75 mm to 100 mm) and the gap of the air layer (5 mm) to ensure good thermal performance and a heat transfer coefficient (U-value) below 0.5 W/(m²·K).
Connection Node Manufacturing Equipment: Connection nodes are crucial for the seismic adaptability of container houses. Equipment must be capable of manufacturing a dual-fixing mode of "wedge lock + high-strength bolt" to ensure that nodes produce a self-locking effect under horizontal shear forces, improving seismic performance. For example, the wedge lock is made of 45# steel after heat treatment, with a bevel angle designed at 15 degrees, which can control displacement within 3 mm in vibration table tests simulating an 8-degree rare earthquake.
Surface Anti-Corrosion Treatment Equipment: The coating system uses a combination of "epoxy zinc-rich primer + polyurethane topcoat," with the primer containing more than 80% zinc powder and the topcoat incorporating nano-silica particles. Treatment equipment must have spraying and curing processes to ensure that the coating system withstands 1000 hours of salt spray tests without showing red rust, equivalent to a 15-year protection cycle in coastal or industrial pollution environments.
Modular Assembly and Installation Equipment: Modular assembly and installation equipment for container houses must be efficient and precise to support rapid delivery and flexible layout. For example, Suzhou Zhongnan's quick-assembly containers can be installed in just 2 hours per unit, supporting on-demand splicing and combination, and enabling the construction of 10 standard dormitories in one day.
