AI Technical Summary
Existing ceilings are prone to cracking at the joints between panels, and existing methods of sealing joints have poor corrosion resistance and adhesion, leading to easy detachment of the finishing material.
The system employs a combination of insert strips and joint sealing strips. The insert strips have wedges and grooves at the bottom and are fixedly connected to the ceiling panel via nails. The joint sealing strips are also firmly connected to the ceiling panel. The corrosion resistance and strength of the polyurethane board are utilized to prevent the nail protrusions from rusting.
It effectively prevents cracking at the joints of ceiling panels, improves connection stability, avoids damage to the finishing materials due to rust spots, and ensures the integrity of the ceiling appearance.
