Wall hanging board is a new generation of wall decoration materials. It has good thermal insulation, waterproof and fireproof, seismic and compressive resistance, corrosion resistance, easy to clean, environmental protection, recyclable performance. It is not subject to the construction requirements of seasonal environment, and is gradually replacing the traditional exterior materials. In this stage, we will discuss the construction standards for metal exterior walls.
Lightning protection
The base steel structural layer of the metal walls and roof shall have its own lightning protection system, which shall be effectively connected to the main body of the building. The bottom of the main body should be connected with the lightning protection foundation, and take comprehensive lightning protection measures.
To prevent
In the light steel villa wall panel and metal base direct contact set up ventilation anti-noise layer, reduce the intrusion of noise.
Corrosion protection
Fluorocarbon coating should be sprayed on the surface of the exterior aluminum plate, and the surface of the steel plate in contact with the outside world should also be coated with fluorocarbon coating. A waterproof layer is arranged at the contact point between the surface layer and the base layer to prevent the electrochemical corrosion of the building roof and structure layer
Heat preservation
Make the overhead layer, combined with the thermal insulation external wall material, to achieve a certain thermal insulation effect.
