[0002] An atrium usually refers to a courtyard space inside a building. Its greatest feature is that it forms an "outdoor space" inside the building. It is a unique form of architectural design that creates a sense of isolation and integration with the external space, or a way for the internal environment of a building to share the external natural environment.

[0003] At present, atriums are widely used in various large and medium-sized public buildings such as office buildings and shopping centers. They are also called four-season halls or shared halls. The top of the atrium can be made of glass on a light grid structure. Some are also made into movable glass high roofs, namely atrium light sheds.

[0004] In the related technologies, the on-site atrium sightseeing shed has a dense frame, beams, and it is difficult to maintain the glass of the light shed in a long-term and timely manner, which seriously affects the indoor visual experience. At the same time, the light shed curtain wall glass has a weakened resistance to direct sunlight.
