Multilateral tongue-and-groove cast stone plate and paving method thereof

The invention relates to the field of metallurgical equipment, in particular to a multilateral tongue-and-groove cast stone plate and a paving method thereof. The multilateral tongue-and-groove cast stone plate is characterized in that the edge of a cast stone plate body is provided with a tongue-and-groove structure, and the horizontal projection of the cast stone plate body is of a square structure; the cast stone plate body comprises a cast stone plate body (1) with tongue-and-groove structures on three side edges, or a cast stone plate body (2) with tongue-and-groove structures on four side edges, or a cast stone plate body (3) with tongue-and-groove structures on two edges. According to the cast stone plate and the construction method thereof, paving work of the cast stone plate can be rapidly and efficiently completed, the paved cast stone plate is good in integrity, the cast stone plate cannot fall off in the using process due to the connection problem between the cast stone plates, the cast stone plat
