Introduction of wind-driven curtain wall
1,About the research and development background and concept of wind-driven curtain wall
Most of the existing decorative building exterior walls (such as glass curtain walls and stone curtain walls) lack a sense of dynamics and have high structural requirements. In order to meet the decorative requirements of buildings, wind-driven curtain walls appeared. Wind-driven curtain wall is also called wind chime curtain wall. Simply put, its principle is to use dynamic wind force to simulate the effect of wind blowing. Let the surface dance in the air with the wind, light, agile, and natural. The landscape wall is its own scenery. The combination of different elements, the matching of different materials, the use of different colors, and even the application of different technologies can give people a different experience.
2, Main forms of wind-driven curtain walls
(1) wire rope decorative structures
Suitable for curved surfaces, both sides are display surfaces, and one side faces the glass or viewing surface.
(2) Skeleton decorative structures
Suitable for small gaps, seamless joints, non-shaped surfaces, surface spray painting or patterns, etc. It can form a modular installation with high efficiency.
(3) Other personalized customization decorative structures
3,The shape of the wind-driven building exterior walls
According to the design of each facade, the shapes of the wind blades also emerge in endlessly. From the ancestor rectangle, now new shapes such as rhombus, polygon, circle and so on are added.
4,Materials of wind-driven building exterior walls
Wind-operated building exterior walls are generally made of metal, because this material has strong reflective power and unique metallic luster, and adds a lot of color to the landscape wall; there are aluminum plate wind-operated curtain walls, stainless steel wind-operated curtain walls, copper material wind-operated curtain walls, PET Material wind-driven curtain wall, etc.
(1). Stainless steel mirror material building exterior walls, as the preferred material for wind-driven curtain walls, has the following advantages and disadvantages:
Advantages: Stainless steel has the characteristics of durability, beauty, antifouling and anti-corrosion properties, ensuring that the outer surface of the wind driven curtain wall is durable and new.
Disadvantages: Stainless steel has high density and weight; high cost.
Size range: thickness of hanging piece is 0.5-0.8mm, width 50-300mm, height 50-400mm
(2) Aluminum plate material building exterior walls: The aluminum wind-driven curtain wall has a unique texture, can be spray-painted, can have diversified appearance and shape, and can be perfectly combined with glass curtain wall materials and stone curtain materials.
Advantages: light and soft, good strength, good corrosion resistance, good processing performance, easy to regenerate, high performance-price ratio, favored by owners.
Disadvantages: It is difficult to form a good mirror effect.
Size range: thickness of hanging piece is 0.8-1.0mm, width 50-300mm, height 50-400mm
(3) Other materials decorative structures: copper sheets or PET sheets, etc.
The above two materials have obvious advantages, but the disadvantages are more prominent. The unique shape of the copper sheet reflects the aura of tall and royal family, but due to its high cost, it cannot be suitable for most projects. PET sheets are chemically synthesized materials, which have the advantage of being easy to shape and low cost; the disadvantage is that they are not suitable for outdoor use in harsh environments. Poor corrosion resistance and weather resistance.
Neither copper sheets nor PET sheets are used as mainstream wind driven curtain wall materials.
