In actual application, it is found that the connection stability is poor when using this connection method.

[0005] In addition, Chinese patent CN202321882537.6 discloses a spliced ​​fireproof rock wool board, which supports a first spliced ​​board, multiple second spliced ​​boards and a third spliced ​​board through a support plate, and improves stability by slidingly connecting them in a connecting groove through a connecting block.

[0006] The spliced ​​fireproof rock wool board is provided with matching structures such as an insertion plate, an insertion groove, a limit plate, and a limit groove, and adopts an insertion connection method. When the size of the rock wool board is large, a larger assembly space is required, which affects the assembly efficiency. Utility Model Content
