Unit bracket, bracket and bracket construction method for attaching to base material and wall using the same

The present disclosure has the following configurations. The present disclosure relates to a unit bracket in a square shape, in which outer surfaces of four surfaces of the unit bracket are formed with locking projections configured to insert a metal or plastic panel, and a center portion of the unit bracket is formed with a mesh part to be formed such that the bonding is possible at a vertical tensile strength and a horizontal tensile strength having desired forces even if the unit bracket and a wall or a base material are bonded with an adhesive, in order to bond the unit bracket to the wall or the base material.
