The invention relates to a stone ceramic plate hanging buckle component which comprises a first pendant and a second pendant respectively mounted at the back part of a stone ceramic plate, a positioning corner fastener with a support part for fixing with the wall surface, and a fastener for respectively limiting the second pendant and the first pendant on the upper side and the lower side of the support part, wherein the fastener comprises a pressure plate and a hanging hook positioned at the lower end of the pressure plate; and the first pendant comprises a T-shaped groove which comprises anupward opening and is matched with the hanging hook, the hanging hook is inserted into the T-shaped groove of the first pendant for lifting the first pendant, the second pendant comprises a groove with a downward opening, and the upper end of the pressure plate is inserted into the groove and leans on the groove wall on one side of the groove, which is near to the wall surface. The stone ceramic plate hanging buckle component has simple structure, a keel framework does not need to be mounted, the dry hanging is not required, the positioning is fast, the stress on all plate blocks is more uniform through hanging (lifting)-supporting-leaning-adhering combination, the seismic performance is better, the detachment, the mounting and the replacement are more convenient, the mutual interference can be avoided, the problem of a cold/thermal bridge of a stone ceramic plate curtain wall can be thoroughly solved, and the stone ceramic plate hanging buckle component has better economic benefits and energy-saving effect.
