For each single horizontal strip 1 , each horizontal strip 1 contains nine transverse fitting grooves

11, nine groove bottoms 12, and eight transverse strips 13. The opening in the transverse strip 1 forms nine transverse fitting recesses 11, each of which is located at the bottom of each corresponding lateral fitting recess 11, and each lateral strip 13 is located adjacent to each adjacent two Between the bottoms 12 of the grooves.

Figure 4 is a schematic view showing the structure of a longitudinal strip in the embodiment of the present invention. For each individual longitudinal strip 2, each longitudinal strip 2 comprises nine longitudinal fitting recesses 21, nine recessed tops 22, and eight longitudinal strips 23, respectively. The longitudinal strip 2 defines nine longitudinal fitting recesses 21, each of which is located at the top of each of the corresponding longitudinal fitting recesses 21, and each of the longitudinal strips 23 is located at each adjacent two Between the tops 22 of the grooves.

In the present embodiment, the upward direction in the directions of FIGS. 1 and 2 is that the skeleton unit 100 receives the top side of the mosaic cover fastening installation, and the horizontal strip 13 and the longitudinal strip 23 are received by the mosaic cover. The sides are defined as the top side of the transverse strip 13 and the top side of the longitudinal strip 23, the other side being defined as the bottom side of the transverse strip 13 and the bottom side of the longitudinal strip 23.
