1. The bonding compressive strength between the protective layer and the insulation layer is low, or the wall is hollowed out with rock wool colored steel plates.
Preventive measures: The color steel plate will layer the development trend of the protective layer, leave gaps, and do a good job of sealing and moisture-proof, in order to reduce shortening and temperature stress.
2. Due to the convergence of ground stress at the edges of doors and windows, there are systematic loopholes in the protective layer and decorative layer.
Preventive measures: Use micro anti rust cement mortar or closed cement mortar with high bonding compressive strength, small shortening deformation, and certain ductility. Due to the material being too soft, the thickness of the anti rust cement mortar is 25-30.
3. The protective layer and decorative layer are greatly shortened and deformed, leading to loopholes in the system that creates diseases.
Preventive measures: Using steel wire mesh or steel wire mesh sandwich chocolate color steel plate for high-rise building. On the one hand, the steel wire mesh may increase the proximity between the solid layer and the insulation layer and protective layer, and on the other hand, it may also shorten the ground stress and the discrete variable stress between the protective layer and the decorative layer, thereby achieving the overall goal of reducing and avoiding gaps.
