Connection System and a Mullion of Curtain Wall exterior provides a structural connection between the Mullion and a structural Element, comprises a clip Connection hooked with an Upright, where the clip is coupled with the amount of sliding.

摘要

A mullion connection system for resisting wind load reactions using a connection clip structurally engaged with a mullion without a hole or a fastener penetrating into the mullion surface. The connection clip can undergo stress-free vertical sliding relative to the mullion along the entire length of the mullion without impairing the structural connection strength; therefore, the building construction tolerance in the vertical direction is eliminated as a design consideration of the curtain wall system. The design also eliminates the need for pre-fabricating mullion holes for the connection locations. The design does not require the pre-determination of the elevation of the connecting point and thus is most beneficial for a curtain wall renovation project where the available locations in the building structure for structural connection cannot be determined prior to the demolition of the existing wall. The uninterrupted mullion tube cavities can be conveniently utilized for inter-floor distribution of utility lines.
