The shape of the large-scale scaffold is similar to that of the small T-shaped scaffold, except that the branches are tiled, and the scaffold area is larger than that of the small T-shaped scaffold. The trunk is erected on the shelf, and the top is cut when the height reaches the shelf surface. Then choose two vigorous branches as the main branches, extending to both sides along the central main filament. As a result, the mother branch and the main branch are tied to the surface of the frame at right angles. Therefore, the branches are also tiled with the surface of the frame.
