Description

Technical Field

Due to construction errors, it may lead to the inability to install the wall, or the construction space during installation becomes smaller, posing a safety hazard.

[0006] 2. The traditional connection method cannot make the external hanging wall panel adapt to the deformation of the main steel structure. When the deformation of the main steel structure is large, the connection node may be damaged, resulting in the falling of the wall panel.
