[0013] As a preferred technical scheme of the above, a flexible joint is formed between the two adjacent wallboards after installation.

[0014] As a preferred technical scheme of the above, a shock insulation pad is installed in the flexible joint between the two vertically adjacent wallboards, and the shock insulation pad is installed in the flexible joint through interference fit.
