The decorative facing plate 4 is limited between the support keel 2 and the fastener 5.

[0029] In an optimized implementation manner, the decorative facing plate 4 is a foam ceramic concrete plate. Compared with the traditional method of bonding and anchoring solid lines on the wall body 1, this application uses the embedded plate 3 and the support keel 2 as a framework, and the foam ceramic concrete plate as the surface layer, which can improve the connection stability between the decorative line and the exterior wall. At the same time, it reduces the amount of foam ceramic concrete used, ensures the service life of the decorative line, and reduces the construction cost. Moreover, the foam ceramic concrete plate can also be used as a heat insulation material. A cavity is formed by enclosing between the decorative facing plate 4 and the wall body 1. The decorative facing plate 4 can further be used as a heat insulation layer. The cavity formed between the decorative facing plate 4 and the wall body 1 can reduce the heat conduction rate and play a further heat insulation effect.

[0030] In this embodiment, the thickness of the foam ceramic concrete plate is 30 mm. Of course, in order to improve the heat insulation effect, the thickness of the foam ceramic concrete plate can be appropriately increased.
