After more than 30 years of development, domestic building curtain walls have established a national industry standard system and completed a large number of engineering practices. With the continuous development of the economy, the annual output value of the building curtain wall industry has shown a steady growth trend. However, in recent years, safety accidents of glass curtain walls have occurred frequently, and the "fashion labels" in these cities seem to have become "hidden killers" in high altitude. At the same time, people's attention to the safety inspection and maintenance of glass curtain walls is far from enough, exposing many safety problems and causing property losses to varying degrees Serious social impacts such as personal injury.
Overview of Glass Curtain Walls
Glass curtain walls are divided into frame glass curtain walls, point supported glass curtain walls, all glass curtain walls, and unit type glass curtain walls according to their different structures.
1. Frame glass curtain wall
Frame supported glass curtain wall is a glass curtain wall supported by a metal frame around the glass panel.
2. Point supported glass curtain wall
Point supported glass curtain wall is a glass curtain wall composed of glass panels, point supported devices, and supporting structures. The supporting structure forms include glass rib support, single steel or steel pipe support, truss support, and tension rod cable system support structure.
3. Full glass curtain wall
All glass curtain wall is a glass curtain wall composed of glass ribs and glass panels.
4. Unit type glass curtain wall
Unit type curtain wall refers to a basic unit of curtain wall structure made of various wall panels and supporting frames in the factory, which is directly installed on the main structure of the building curtain wall.
With the rapid economic growth, China has become a major user of building curtain walls, and people's requirements for building curtain walls have gradually increased. However, due to the fact that most of the early use of building curtain walls reached their service life, various problems may occur, resulting in safety hazards in the use of curtain walls.
Inspecting and testing the structure of existing glass curtain walls, identifying existing problems in a timely manner, and repairing and handling them will help extend the service life of glass curtain walls and improve their safety performance.
