This dramatic joinery combination hails from temples and structures throughout Asia. If you have a four sided structure and need a clear span without the traditional tie beams over head or just want to add a cool feature to a frame, then this is the answer.
The purpose of this joinery combination is to resist the outward thrust that the hip (blue) puts into the corner joint. It consists of a dragon beam (yellow) and the dragon brace (purple). The dragon beam acts as a tie beam, taking the outward thrust of the hip and transfers that load into the dragon brace. Which in turns transfers it to the plates. Structural screws are used throughout to aid in installation and its overall strength.
