Dry hanging sandstone plate is how to construct
The internal and external surface treatment of sandstone: the outer surface of the stone should be the protection of the brush (commonly used silicone class), the back of the sandstone should be equipped with fiberglass mesh, for the tilt of the curtain wall must be equipped with fiberglass mesh. All of the above measures may increase the strength of the stone panel, but it is still calculated according to the strength of the sandstone itself.
However, it is necessary to pay attention to the physical properties of sandstone itself, such as porosity, strength and low. The best area of not more than 1 square meters, although some engineering sandstone thickness to do 30mm, but for security reasons, it is best to do 40mm thick. If the height of sandstone curtain wall exceeds 100m, special technical scheme should be demonstrated.
At present, there is no relevant specification for sandstone, its production, installation process can be implemented according to JGJ133-2001 reference.
