Why Do Many Buildings Use Building Curtain Walls? -WJW Aluminum Supplier Aluminum

What is a building curtain wall?

Unlike the filling wall, the building wall has the following characteristics:

1. It is a complete structural system composed of panel and support structure.

2. It can withstand the large deformation on its own plane, or it has sufficient displacement capabilities compared to the main structure.

3. It is a fence structure that does not distinguish the load and role of the main structure.

The curtain wall is usually composed of panels (glass, aluminum, slate, ceramic plate, etc.). The latter support structure (aluminum cross beam pillar, steel structure, glass rib, etc.). . The exterior wall system is supported on the main structure and usually surrounds the main structure. Because there is a wide seam between the board, the connection between the plate and the horizontal beam and column has movement capabilities. The curtain wall can withstand a large deformation of 1/100 in the plane. If the curtain wall is connected to the main structure with bolts, rockers, and spring mechanisms, a large relative displacement will occur between the two. Even if the side displacement of the main structure reaches 1/60, the curtain wall will not be destroyed.

Second, the curtain wall is needed to resist the changes in temperature.

When the external temperature changes, the structure will shrink and swell. If measures are not taken, the structure will be squeezed and crushed in summer, and cracks and fractures will occur in winter. Therefore, long roads should be divided into rational, and long buildings should also be divided into several parts with temperature seams, thereby reducing the impact of temperature changes.

Long buildings can be divided into vertical temperature seams; however, high -rise buildings cannot be divided into horizontal seams, because the floor behind the horizontal seam cannot be hung up.

Because the temperature changes of high -rise buildings cannot be solved by segmented methods, there is only one solution: the entire structure is closed with the building curtain wall, so that the structure is indoors, no longer changes the temperature, will not cause damage to the structure, ensure the subject, and ensure the subject. Structure safety, this is one of the main reasons for high -rise buildings to use building curtain walls.

The traditional brick walls and block walls are filled on the planes of the beams and columns. Some beams and columns are exposed to the outdoor atmosphere and are directly affected by temperature changes. Therefore, filling walls cannot solve the problem of temperature changes and it is difficult to use in high -rise buildings.

Third, how to achieve energy -saving and consumption reduction of curtain walls

As a large family with high energy consumption, the energy saving of glass curtain walls is a problem that most curtain wall engineers and doors and windows workers urgently need to solve. So, how can we maximize energy in the general glass curtain wall project? The first is to choose new energy -saving glass materials; the second is to use low -amplitude glass and multi -functional coating glass; the third is to use thin -film thermal reflection composite glass; fourth, a good glass shading design.

At present, the main measures to improve glass curtain wall insulation and moisturizing performance are: glass mainly uses low E glass, thermal reflected glass, hollow glass, multi -screen hollow glass and other glass treatment technologies to reduce the direct radiation of solar glass; the profile mainly uses aluminum -plastic composite composite composite High heat -resistant materials such as materials and thermal aluminum profiles.
