In this embodiment, the edge of the frame stiffener 21 is flanged (or the edge is thickened) to enhance the structural strength of the periphery of the frame stiffener 21, so that the frame stiffener is not easily deformed under stress, and is prevented from cracking or wrinkling.

Further, the reinforcing rib assembly 20 further includes an inner reinforcing rib 22, the inner reinforcing rib 22 includes a main reinforcing rib 23 and an auxiliary reinforcing rib 24, and the main reinforcing rib 23 and the auxiliary reinforcing rib 24 are disposed on the inner side surrounded by the frame reinforcing rib 21 and are in central symmetry along the central axis i and the central axis j in the length direction and the width direction. The height of the main rib 23 is higher than that of the auxiliary rib 24, and the thickness of the main rib 23 may be equal to or greater than that of the auxiliary rib 24. In the type of the reinforcing beads (refer to the main reinforcing bead 23 and the sub-reinforcing bead 24), a bar-shaped reinforcing bead or a columnar lacing wire, or a combination of both may be selected. This embodiment is optionally a bar stiffener. By setting the auxiliary reinforcing ribs 24, the height of the local reinforcing ribs inside the frame reinforcing ribs 21 can be reduced firstly, so that the construction convenience is improved, and meanwhile, the relative quality and cost of the template are relatively reduced.
