In this case, the first and second reinforcing

ribs

115 and 116 may include a third reinforcing rib 117 extending to contact the inner surface of the quadrangular plane 111.

Each end of the first, second and third reinforcing

ribs

115, 116, and 117 forms an internal skeleton of the multi-faceted block 110 that is contacted with each other during assembly of the first and second split members.

Accordingly, the multi-faceted block body to be assembled can increase the internal strength by the first, second and third reinforcement ribs, thereby increasing durability while preventing damage caused by an impact transmitted from the outside.

As shown in FIGS. 1, 3, and 4, the connecting rod 120 includes a first catching hole 121 formed in a central region of the square plane 111 and a center of the plurality of square slopes 112.
