Curtain wall development prospect

  Curtain wall is the outer wall of the building, not load-bearing, hanging like a curtain, so it is also called “curtain wall”, is a light wall with decorative effect commonly used in modern large and high-rise buildings. Composed of panels and supporting structural system, relative to the main structure has a certain displacement capacity or its own deformation capacity, does not assume the role of the main structure of the building envelope or decorative structure (external wall frame support system is also a curtain wall system).
  Structural form: common glass curtain wall structural form: hidden frame, half hidden frame, bright frame, point type, full glass and so on.
  1, the quality of light, in the same area of comparison, the quality of the glass curtain wall is about 1/10 ~ 1/12 of the painted brick wall, is the marble, granite veneer wet method of the wall is 1/15, is the concrete hanging plate 1/5 ~ 1/7. General building, the mass of the interior and exterior walls is about 1/4 ~ 1/5 of the total weight of the building. Curtain wall can greatly reduce the weight of the building, thus reducing the cost of foundation works.
  2, the design is flexible, the artistic effect is good, the architect can according to their own needs to design a variety of shapes, can present different colors, and the surrounding environment coordination, with lighting and other buildings and natural integration, so that high-rise buildings reduce the sense of pressure.
  3. Strong earthquake resistance, flexible design, strong wind resistance and earthquake resistance, is the best choice for tall buildings.
  4, systematic construction, systematic construction is easier to control the construction period, and the time is shorter.
  5, modernization, can improve the building novel, scientific and technological, such as photovoltaic energy-saving curtain wall, double ventilation ventilation curtain wall and other intelligent technology supporting design.
  6. It is convenient to update and maintain, because it is built in the outer structure of the building, it is convenient to maintain or update it.
  The development trend
  1, from heavy to lighter plate and structure (natural stone thickness 25mm, new materials up to 1mm).
  2, less variety gradually to more types of plates and richer colors (currently there are stone, ceramic plate, glass ceramics, high pressure laminate, cement fiber board, glass, inorganic glass, clay board, ceramic protection board, metal plate and other nearly 60 kinds of plates used in the external wall).
  3, higher safety performance.
  4, more flexible and convenient construction technology.
  5, higher waterproof performance, prolong the life of the curtain wall (from closed curtain wall to open curtain wall).
  6, environmental protection and energy saving (nowadays Europe and the United States construction market is more commonly used for metal decorative insulation board, by color paint after aluminum zinc alloy carved decorative surface, polyurethane insulation layer, glass fiber cloth composite;Taking into account decoration and heat preservation and energy saving function, the finish paint is colorless for 10-15 years, and the overall service life can reach 45 years).
