Construction Site Container House Processing
The processing of container houses for construction sites requires special attention to four core aspects: structural design, material selection, production process, and installation specifications.
Structural design must balance strength and flexibility The core framework of container houses should use high-strength steel, such as hot-dip galvanized cold-formed steel or weathering steel, to ensure stability under extreme conditions (e.g., typhoons of force 12 and earthquakes of magnitude 8). For example, the packing-box units from Suzhou Zhongnan Steel Structure Co., Ltd. feature a fully steel framework with a wind resistance rating of force 12 and an earthquake resistance rating of magnitude 8, with a frame deformation rate of only 0.18%, well below the industry's acceptable threshold of 0.3%. Additionally, modular design should support multi-level stacking and flexible assembly, such as by adding C-shaped steel purlins to distribute loads, ensuring structural stability even when three containers are stacked.
Material selection must suit the usage scenario Wall and roof panels should be chosen based on climatic conditions for thermal insulation. For instance, in cold regions, 100mm rock wool sandwich panels with a moisture-proof aluminum foil layer can be used to reduce condensation risks; in humid environments, high-weather-resistant polyester resin-coated steel plates should be employed to enhance corrosion resistance. Window and door systems must be sealed to prevent rainwater infiltration, while internal water and electrical lines should be pre-embedded to avoid structural damage from secondary drilling on-site.
The production process must be standardized and refined The processing workflow includes steel structure welding, wall panel prefabrication, water and electrical pre-embedding, and corrosion protection. Welding should utilize automated equipment to ensure precision, such as by adding purlins between bottom beams to distribute loads; corrosion protection should involve shot blasting for rust removal followed by spraying with zinc-rich primer and polyurethane topcoat, extending service life to over 15 years. Thermal insulation performance can be optimized through a thermal-break lining structure, where hard polyurethane foam is filled between the steel frame and interior wall panels, reducing heat exchange efficiency by approximately 40%.
Installation specifications must strictly adhere to industry standards On-site assembly should be carried out by professional teams to ensure secure connection nodes. For example, Zhongnan's quick-assembly containers can be installed in just 2 hours per unit and support customized assembly combinations; in contrast, ordinary products with non-standard installation processes may take over 8 hours per unit, leading to project delays. Furthermore, before installation, the product's wind and earthquake resistance test reports must be verified to avoid using unqualified, generic products, which typically have a frame deformation rate exceeding 1.2% and pose safety risks.
