Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fastener for attaching a curtain wall as an outer wall of a building , and a curtain wall mounting structure using the fastener .
[0002]
[Prior art]
As is well known, when the outer wall of a building is formed by a curtain wall such as a precast concrete plate or a metal panel, the mounting structure can be displaced by following the interlayer deformation that occurs in the building during an earthquake. In general, the curtain wall is generally connected to the building so as to be horizontally displaceable (sway method) or relatively rotatable (rocking method). The sway method allows the horizontal displacement (that is, the sliding to the side) in the plane of the curtain wall (in the vertical plane along the curtain wall itself) following the interlayer deformation, and the locking method is the curtain This allows rocking in the plane of the wall.
