Further, the steel casing is connected with the outer prefabricated plate as a whole through prefabricated nuts.

The beneficial effects of the utility model are:

1. The decorative lines and the laminated wall panels are connected by bolts and anchored into the cast-in-place concrete, with good overall stability and high safety factor;

2. The decorative lines and laminated wall panels are produced in a factory integratedly. To change the existing decorative lines, holes need to be drilled at the construction site, and the wet work volume is large, which improves the construction efficiency and ensures the project quality;

3. The integrated prefabricated laminated wall panel is suitable for any form of decorative lines;

4. The deviation caused by the production error can be effectively adjusted by pre-embedding the steel casing to ensure the horizontality and verticality of the lines.

5. The prefabricated decorative lines are detachable and replaceable.

6. Less affected by the production process, easy to repair the exterior surface.
