The tension spring 408 is installed in the inner cavity of the insertion rod 403. The two ends of the tension spring 408 are respectively fixedly connected to the two connecting shafts 407. Under the action of the tension spring 408, the spike portion of the anti - detachment rod 406 is driven to rotate outwards to limit the polystyrene board 2, preventing the polystyrene board 2 from cracking and falling off after long - term use, and reducing the maintenance cost.
[0028] In a preferred embodiment, during installation, one end of the bolt 404 is inserted into the expansion nut 402.

The bolt 404 is screwed into the expansion nut 402, and the expansion nut 402 expands to fix the insertion rod 403 on the side wall of the wall body 1. Subsequently, the first mortar layer 3 is bonded to the surface of the wall body 1, and the polystyrene board 2 is installed on the side wall of the wall body 1. The insertion rod 403 is inserted into the inner cavity of the polystyrene board 2. Under the action of the tension spring 408, the spiked portion of the anti-detachment rod 406 is driven to rotate outwards to limit the polystyrene board 2 and prevent the polystyrene board 2 from cracking and falling off after long-term use, reducing the maintenance cost.
[0033] By setting the flame retardant layer 5, the flame retardant effect can be effectively improved, and the safety performance of the structure can be enhanced. Moreover, by setting the fiber mesh cloth 6 between the flame retardant layer 5 and the second mortar layer 7, on the one hand, the flame retardant performance can be improved, the adhesion of the second mortar layer can be enhanced, a mechanical anchoring effect can be provided, the tensile strength of the second mortar layer can be increased, and the generation of cracks can be reduced.
