The corrugated board 1 can be used as a reference to ensure the flatness of the relative position, which can simplify the installation of the rock wool sandwich panel 2 and ensure the quality of the interior wall of the rock wool sandwich panel 2.

[0109] It should be noted that, although the above embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, changes and modifications made to the embodiments described herein, or equivalent structures or equivalent process changes made using the contents of the present invention specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present invention.
