[0011] Preferably, the second reinforcing mesh is made of crack-resistant steel wire mesh, which makes the first reinforcing mesh structurally strong. The second reinforcing mesh is located on the side of the skeleton away from the fiber cement layer. The structural strength of the foamed cement layer is improved by the second reinforcing mesh and the skeleton, and the stability and anti-cracking effect of the foamed cement layer are enhanced.

[0012] Preferably, the first support reinforcement and the second support reinforcement are made of metal material with high structural strength. The first support reinforcement and the second support reinforcement can effectively increase the structural strength of the foamed cement layer.
