Internal wall corner mounting structure for fitting mounting of wood veneer framework

The invention discloses an internal wall corner mounting structure for fitting mounting of a wood veneer framework. The internal wall corner mounting structure comprises wood veneers (1), square tubes (2), a corner connector (4) and an L-shaped positioning sheet (7), the square tubes (2) are arranged on the back sides of the wood veneers (1), the corner connector (4) is fixed on a building wall (9), the square tubes (2) are fixed with corner connector (4) via a through bolt (8). At an internal wall corner, one wood veneer (1) is connected with the other wood veneer (1) to form the internal corner, one lateral side of the L-shaped positioning sheet (7) is in socket connection with the square tube (2) on the back sides of one of the wood veneers (1) of the internal corner, and the other lateral side of the L-shaped positioning sheet (7) supports the other one of the wood veneers (1). By a steel structured keel base layer, the problem about deformation of a base layer is effectively solved, completeness of the front surfaces of the wood veneers is guaranteed, and decoration effect is good. The internal wall corner mounting structure is simple and easy to operate and convenient to mount and dismount, and construction efficiency is improved while decoration quality is guaranteed.
