The invention discloses a stone honeycomb core integrated board. The stone honeycomb core integrated board comprises a board body, and the board body comprises a bottom board main body, a backboard main body, a honeycomb core and a stone panel. The cross sections of the bottom board main body and the backboard main body are each in a U shape, the bottom board main body and the backboard main body are oppositely arranged, mutually overlapped and mutually engaged, the honeycomb core is arranged between the bottom board main body and the backboard main body, and the surface of the honeycomb core is coated with composite glue; and a fixing device is arranged at the lower end of the board body and comprises two fixing inserting plates and a fixing frame. The stone honeycomb core integrated board adopts the structure of the stone panel and the honeycomb core, improvement of the sound absorption and heat insulation effects of the board body is facilitated, and through the stone panel, a building outer wall on the whole is more beautiful; and a novel mounting structure is adopted, only the board body needs to be directly inserted in mounting, the mounting height of the board body can be adjusted, meanwhile, the board body can be directly taken down only through one-time light pressing, and later-period replacement and maintenance are facilitated.
