Description

Technical Field

[0002] As an important component of prefabricated buildings, prefabricated walls are increasingly being adopted, in addition to traditional prefabricated concrete wall panels. New materials such as lightweight steel frame composite walls, autoclaved aerated concrete panels, and fiber-reinforced composite materials are becoming more common, offering advantages in lightweighting, thermal insulation, and earthquake resistance. Prefabricated walls, combined with energy-saving designs such as integrated sandwich insulation walls, meet the requirements of low-carbon buildings.

[0003] For example, Chinese patent document CN205530817U discloses a prefabricated wall for rapid installation, which includes a wall panel and a bracket and a hanger fixedly connected to the upper and lower ends of the wall panel, respectively.
