Natural Stone Curtain Wall
The stone curtain wall of China is theion and use power. According to the incomplete statistics, the average decorative stone plate used in curtain wall decoration is about 25 million square metre in domestic, it is about 140 million sets of the stone material curtain wall.
Stone Curtain Wall
Stone curtain wall are usually composed of the Slate supporting structure (aluminum beam column, steel structure, glass rib, etc.) composition, it is a building palisade structure which do not assume the main structure load and function.
Generally, the stone curtain wall installs by dry hanging, for that the dry hanging is relatively cheaper than the wet stick on the cost, but there are also some benefits. Dry hanging is higher in safety reliability, which is not easy to fall, so if the metope is higher, it usually apply the dry hanging. While it is easy to appear the whiskering phenomenon for the wet stick of exterior wall, and it will influence the impressions of curtain wall. The freezing-thawing resisting of wet stick would be a little weak, so it is easy to appear some problem in freezing area.
Advantage of Using Stone Curtain Wall to Décor:
1. Natural material with bright glittering and translucent, hard permanent, which shows the noble and elegant.
2. Frost resistance: in damp condition, stone can resist freezing and thawing, and won’t occur significant destroyer, this performance is called frost resistance. Below zero centigrade 20, the freezing will happen for the rock pore water in those low temperature, the expansion of internal pore water would be bigger of 1/10 than original volume. If the rock can't resist this power that generated from the expansion, it will appear the phenomenon of destruction.
3. Compressive strength: it would be different of the stone compressive strength, due to the mineral composition, crystalline degree of finish, the uniformity of cementing material, load area, load action and cleavage to factors such as the Angle. It would be in high strength, if other conditions are the same, usually crystal grain size is very fine and binding together each other to the density of the material.
But if use the stone material curtain wall, to ensure the safety of construction and use , it should be done according to the need of engineering design, and connecting with the stone material characteristics.
