Container House Splicing Methods
The splicing methods for container houses mainly include three types: bolt connection, interlocking, and modular combination splicing.
Bolt-connected splicing is the primary method for assembling container units. This structure uses standard plates connected by bolts to form the house frame. There are multiple connection nodes along the load path, and the tightness of each node directly affects the overall stability. In practice, the bottom frame is first installed on a flat ground or workbench, with the box corners connected to the bottom beams using hexagon socket bolts. After alignment (ensuring the diagonal difference of the bottom frame is ≤3mm), the bolts are tightened. Subsequently, π-shaped secondary beams are installed according to the positioning holes on the long beams and fixed with self-tapping screws and round-head drill tail screws. Finally, the floor base plate is laid and the floor splicing is completed. This splicing method is suitable for scenarios requiring frequent disassembly and assembly, but regular inspection of bolt tightness is necessary to maintain structural stability.
Interlocking splicing achieves rapid assembly through mechanical interlocking between plates. A typical structure is the quick-assembly, fully-furnished container house, where the base, roof, door panels, side panels, and rear panels are connected through interlocking slots and locking holes. After aligning the interlocking buckles on both sides of the door panels with the locking screw holes on the side panels, bolts are used to secure the assembly. This method's plate interlocking structure provides a limiting effect, ensuring no gaps even if the screws loosen, effectively guaranteeing the house's airtightness. It is suitable for temporary buildings or emergency housing with high airtightness requirements.
Modular combination splicing achieves spatial expansion through horizontal splicing, vertical stacking, or staggered design of standardized container units. For example, connecting 2-3 containers to form an integrated living and dining area or creating rich spatial layers through staggered stacking, with the ground floor reserved for a leisure courtyard or passageway. When combining multiple containers, the placement and connection methods of the containers are crucial. Each container serves as an independent unit structure, with functional zoning achieved through I-shaped arrangements or cantilever designs. A wind power project camp in Xinjiang used 180 containers arranged in an I-shape to build a complete living area including dormitories, a canteen, and a conference room within seven days, fully demonstrating the efficiency and flexibility of modular splicing.
