Dazhu Container House Construction
Key points to focus on during the construction of container houses in Dazhu include foundation treatment, structural reinforcement, fire and corrosion prevention, and construction specifications:
Foundation treatment is the basis for the stability of container houses. Before construction, ensure that the foundation is level to avoid tilting or water accumulation issues later. For outdoor long-term use scenarios, it is recommended to build concrete piers at the bottom to enhance overall stability. For example, in a mobile guard post project in Guangzhou, by planning the foundation levelness and pre-embedding drainage pipes in advance, water accumulation problems were effectively avoided, extending the service life of the house.
Structural reinforcement must meet seismic and wind resistance requirements. The corners of container houses need to be reinforced with steel frames to enhance lateral resistance. When stacking multiple containers, the corner fittings must be aligned vertically and locked tightly to ensure a clear force transmission path. According to the Technical Specification for Modular Combined Houses, the seismic fortification intensity should not exceed 8 degrees, the number of floors should not exceed 6, and the height should not exceed 24 meters. For example, in vertical stacking projects such as dormitories or hotels, it is necessary to strictly follow the principle of force transmission through corner fittings and avoid using spot welding as a substitute to ensure structural safety.
Fire and corrosion prevention are crucial for safety. Prohibited filling materials for the enclosure include EPS and other flammable core materials. For crowded places, A-grade rock wool or glass wool should be used, and the fire resistance limit should comply with the GB50016 standard. Steel structures need to be painted with fire-resistant coatings and equipped with escape routes, fire extinguishers, and other facilities. In addition, welding weathering steel (GB/T 4171) should be selected for steel materials, and Q235B or Q345B can be used for non-container components to improve corrosion resistance. For example, in special-purpose projects such as medical containers or laboratory containers, fire and corrosion prevention requirements are stricter, and material qualification certificates need to be carefully checked.
Construction specifications must strictly follow technical procedures. Existing containers must be GB/T12418 inspection-qualified boxes with no defects in beams and columns and complete and reliable corner fittings. When opening large holes or designing cantilevers, stiffness compensation should be achieved through staggered and symmetrical arrangements or the addition of diagonal braces. For example, in the L-shaped enclosure design of trendy guesthouses or cafes, holes are strictly prohibited in the cantilevered sections, and diagonal braces need to be added to ensure structural stability.
