About the Curtain wall

    The curtain wall is the outer wall of the building. It does not bear the weight and hangs like a curtain. It is also called the “curtain wall”. It is a lightweight wall with decorative effects commonly used in modern large and high-rise buildings. It consists of a panel and a supporting structure system, which can have a certain displacement capacity relative to the main structure or a certain deformation ability, and does not bear the external structural protection structure or decorative structure of the main structure (the external wall frame supporting system is also the curtain wall system).

   Brief introduction

  Characteristic:

  1、The curtain wall is an independent and complete overall structural system;

  2、The curtain wall is usually used on the outside of the main structure, and is generally wrapped on the surface of the main structure;

  3、The curtain wall has a certain fretting ability in the plane relative to the main structure.

  Capability

  1、Wind pressure resistance

  2、Rainwater leakage (watertightness)

  3、Air infiltration (air tightness)

  4、In-plane deformation (shock resistance)

  5、Thermal work

  6、Sound insulation

  7、Lightning protection

  8、Fire prevention

  9 、Environmental protection

  10、Sound absorption

  11、Beautiful, decorative

  12 、Energy saving 

  structure type

  Common glass curtain wall structure forms: hidden frame, semi-hidden frame, bright frame, point type, all glass, etc.

  Advantage:

  1、light in mass

  In the comparison of the same area, the quality of the glass curtain wall is about 1/10 to 1/12 of the painted brick wall, 1/15 of the marble and granite facing wetwork wall, and 1/5~1/ of the concrete hanging board. 7. In general buildings, the quality of the inner and outer walls is about 1/4 to 1/5 of the total weight of the building. The use of curtain walls can greatly reduce the weight of the building, thereby reducing the cost of the infrastructure.

  2、Flexible design

 The artistic effect is good. Architects can design various shapes according to their own needs. They can present different colors, coordinate with the surrounding environment, and integrate the building with nature with light, so that the high-rise buildings can reduce the oppression.

  3、Strong earthquake resistance

  Flexible design, strong wind and earthquake resistance, is the choice of high buildings.

  4、Systematic construction

  Systematic construction makes it easier to control the construction period and takes less time.

  5、Modernization

  It can improve the design of novelty and technology, such as photovoltaic energy-saving curtain wall, double-ventilation respiratory curtain wall and other intelligent technology.

  6、Easy to update and repair

  Because it is built on the outer structure of the building, it is convenient to repair or update it.

  Development trend

  1、From bulkiness to lighter sheet and structure (natural stone thickness 25mm, new material thin up to 1mm)。

  2、The variety is gradually moving towards many types of plates and richer colors (currently there are stone, ceramic plates, microcrystalline glass, high pressure laminates, cement fiber silk plates, glass, inorganic glass steel, clay plates, ceramic plates, metal plates, etc. 60 kinds of plates are applied to the outer wall).

  3、Higher security.

  4、More flexible and convenient construction techniques.

  5、Higher water resistance extends the life of the curtain wall (from a closed curtain wall to an open curtain wall).

  6、Environmental protection and energy conservation (currently used in the European and American construction market is a metal decorative insulation board, which is made of color-painted aluminum-zinc alloy engraving, polyurethane insulation and glass fiber cloth; taking into account the decoration and insulation energy-saving functions, topcoat 10- 15 years without fading, the overall service life can reach 45 years).
