Description

[0002] With the emergence of large-scale exhibition centers, art centers, theaters, etc. in domestic buildings, special-shaped buildings have a trend of vigorous development. Such buildings adopt steel structure plus curtain wall from roof to overall building. Metal aluminum plates are widely used in building exterior protection system due to their light weight, low load, low maintenance cost, strong plasticity, diverse appearance and high integration with other curtain wall materials. They are restricted by special-shaped buildings, complex roof steel structure, and curtain wall surface construction is restricted by the construction accuracy of other professions, main structure deviation, and the actual shape of the main structure after final tensioning. The final shape size needs to be determined according to the actual completion of other professions on site. The construction variables are large, which seriously restricts Construction progress; and under the action of earthquake and wind load horizontal forces, relative displacement will occur between the main structures of the building. The curtain wall, as a protective structure suspended on the main structure, not only moves with the main structure, but also has its own movement. Once the curtain wall design does not take into account the displacement capacity relative to the main structure, and does not adopt measures such as elastic movable connections, it will cause deformation of the curtain wall and even the structure, posing a great safety hazard. The current approach to dealing with the deformation capacity of the curtain wall can only satisfy the front and rear deformation in the direction perpendicular to the plane of the curtain wall through the strip holes of the steel angle code, while ignoring the left and right deformation capacity of the curtain wall skeleton, resulting in the curtain wall only being able to deform with the main structure, and having no deformation capacity relative to the main structure.
