The arrangement direction of the first tooth stripes 1311 on the first sub-layer 131 is perpendicular to the arrangement direction of the second tooth stripes 1322 on the second sub-layer 132. It is to be understood that the arrangement directions of the first tooth-like stripes 1311 on the first sub-layer 131 and the second tooth-like stripes 1322 on the second sub-layer 132 are not limited to those shown in fig. 2, and the arrangement direction of the first tooth-like stripes 1311 and the arrangement direction of the second tooth-like stripes 1322 may be perpendicular to each other.

Generally, the overall thickness of the finishing layer 140 and the bonding layer 130 is controlled to be about 20mm, the thickness of the finishing layer 140 is generally about 10mm, so the thickness of the bonding layer 130 is generally 10mm, and tile glue with the thickness of 2mm to 4mm needs to be fully scraped on the back surface of the finishing layer 140 according to the construction process requirement, so that 6mm to 8mm of tile glue needs to be fully paved on the sound insulation coating layer 120 for leveling, bonding and other functions. Therefore, in the present embodiment, the thickness of the first sub-layer 131 is 6mm to 8mm, and the thickness of the second sub-layer 132 is 2mm to 4 mm.
