The invention discloses a special-shaped GRG decorative sheet mounting and structuring system and a decorative sheet structuring and mounting method and relates to the construction, installation and decoration fields, in particular to the special-shaped GRG decorative sheet technology. The technical scheme is that a rotary connecting piece is connected with a basic skeleton and is mounted under a rigid suspender. The rotary connecting piece comprises a spindle which is connected with the rigid suspender, a spindle pendant which rotates along with the spindle, and a skeleton fixing piece which is connected with the spindle pendant and is used for fixing the basic skeleton, wherein the spindle pendant is fastened on the spindle through a fastening piece, and the skeleton fixing piece is connected with the basic skeleton. The special-shaped GRG decorative sheet mounting and structuring system and the decorative sheet structuring and mounting method enable the special-shaped GRG decorative plate with complex angles to be mounted effectively and firmly, the regulation is completed through rotating the spindle pendant to the determined angle and then fixing through the fastening piece, and accordingly the decorative plate can be regulated conveniently and quickly, and the field installation and regulation time is saved greatly.
