The invention discloses an installing structure for sub keels of wall-attached adjusting clips. The installing structure comprises expansion screw bolts (1), the wall-attached adjusting clips (3) and the sub keels (4), wherein a plurality of expansion screw bolts (1) are fixed on the wall surface at intervals; the outer ends of the expansion screw bolts (1) are fixedly provided with lead screws (2); the wall-attached adjusting clips (3) are fixed with the lead screws (2); the sub keels (4) are clamped and connected with the clamping and connecting ends of the adjusting clips (3); the outer sides of the sub keels (4) are provided with a base layer plate (5); and a veneer (7) is arranged outside the base layer plate (5). The installing structure for the sub keels of the wall-attached adjusting clips has the advantages that the requirements of a traditional wood base layer process on fireproof standards, dampness prevention, deformation, environment protection and the like can be met, and the construction work procedures are optimized; the materials are effectively saved, the problem of time consumption of manual work is solved, and the stability of the base layer is also enhanced; and the firmness is better, and the falling cannot easily occur.
