Kangbashi Container House Installation
The installation of container houses in Kangbashi should be carried out in accordance with the characteristics of different types of houses and professional standards. Details are as follows:
Installation of Packing-Box Units:
The installation of packing-box units is a systematic project involving structural mechanics, material connections, and equipment integration. Its independent modules are prefabricated steel frame skeleton systems, with the bottom main beams rigidly connected to corner fittings via high-strength bolts to ensure structural stability. During horizontal assembly, closed-cell rigid polyurethane foam is filled between adjacent side walls as shear keys to transfer horizontal forces. During vertical stacking, the bottom beams of the upper units must be aligned with the top main beams of the lower units, using socket-type positioning devices. Installation workers should tighten the connecting bolts in three steps along the diagonal sequence to avoid local stress concentration. The pipeline system is pre-embedded in the factory and connected on-site via quick-connect fittings, reducing on-site operation errors.
Installation of Color-Steel Temporary Buildings:
Color-steel temporary buildings use sandwich composite panels as the core enclosure material, with a surface layer of galvanized color-coated steel sheets and a core material that can be polyurethane, rock wool, or EPS foam. Foundation treatment should be carried out by compacting or replacing soft soil layers according to geological conditions, and the accuracy of anchor bolt pre-embedding directly affects structural stability. The steel frame adopts cold-formed thin-walled C-section or Z-section steel, and the connection nodes between purlins and columns require double-row staggered self-tapping screws, supplemented by angle steel reinforcing plates to enhance shear capacity. The installation of enclosure wall panels follows the principle of "bottom-up, corner-first, edge-last", with inter-panel tongue-and-groove joints being crucial for waterproofing and airtightness, ensuring tight and seamless connections.
Installation of Light-Steel Houses:
The force path of light-steel houses is "skeleton-connection nodes-foundation", using cold-formed thin-walled steel with concave reinforcing ribs and special cross-sections to enhance the bending stiffness of columns. The enclosure structure uses aerogel-modified composite insulation panels, with low thermal conductivity and polymer thermal break spacers pre-embedded at structural connections, effectively reducing energy consumption losses. Connection nodes introduce "self-locking bite connection" technology, with anti-slip bearing capacity approximately 40% higher than traditional screw connections, enhancing overall structural integrity. Tuned mass dampers are installed within the floor trusses to control floor vibrations and address the "shaking sensation" issue in light-steel structures.
Installation of Prefabricated Panel Houses:
The steel specifications for prefabricated panel houses are determined based on local wind and snow load data, with wall panel materials divided into metal sandwich panels and glass wool composite panels. The roofing system adopts a dual drainage design with gutters and sealing strips, and floor treatment includes graded crushed stone sub-base, concrete leveling layer, moisture-proof membrane, and flooring materials to ensure moisture resistance and flatness. Structural connection technologies involve column base anchor bolt fixation, high-strength bolt connections at beam-column joints, and concealed slot systems for wall panels. On-site installation is carried out in stages: after foundation acceptance, the steel structure main body is hoisted, wall installation is interspersed with pre-embedding of water and electricity pipelines, and roofing systems and wall works are staggered to improve efficiency and safety.
