StoneClip's Support Clip certified by Sheehy & Partners
This is to certify that Sheehy & Partners have checked the design of
the mechanical fixing known as "Support Clip." The Support Clip parameters and design capacities
are summarised below. This limit state loading on the fixings to connect the Support Clip to the
substrate are also provided.
Design Assumptions
The design has been based on the following;
- Support Clip samples provided to the office.
- All components of the clip have been designed in accordance with AS 4673:2001 - "Cold-Formed
Stainless Steel Structures," other relevant codes, and in accordance with widely accepted engineering
principles.
- The load factor applied to Panel Dead Loads is 1.35 in accordance with AS 1170-0:2002
"Structural Design Actions."
- Where Support Clip's are to resist lateral loads they have been designed for a strength limit state
pressure of 2.53 kPa. For lateral wind loadings this is equivalent to buildings in wind region B and
terrain category 2 and for a maximum cladding height of 10m in accordance with AS 1170-2:2002
"Structural Design Actions - Wind Actions."
Support Clip Geometry
Support Clip Design Capacity Table
The following table is for Support Clip carrying a vertical loading and lateral loading.
Each Support Clip is fixed with one countersunk 14 gauge screw through one of the two holes in the Clip
plate. Fixings are to be selected in accordance with fixing manufacturer's documentation.
# The wind area is the maximum area that one Support Clip can resist based on design window pressure
of 2.53kPa, as noted in the design assumptions. For other wind loading situations engineered solutions
based on the above tension capacity may provide increased/reduced wind areas.
* Limit state load.
^ "Cavity" is the distance between the substrate and the inside face of the panel.
Certification
The pull through capacity of the hole in the clip for the screw has yet to be determined through load
testing and the pull through capacity of the hole is therefore not part of this certification.
If the Support Clip installation is completed in accordance with the above design, the StoneClip.com specifications
and sound building practice, and provided that load testing can prove that the tension capacity of the hole is
adequate, then the "Support Clip" mechanical fixing is considered to be structurally adequate.
This certificate does not cover the strength of the tile panel or the transfer of load from the tile panel to
the "Support Clip."
The certificate does not cover the fixing or the substrate to which the clip is attached. Proprietary fixings to
the substrate are to be selected based on the strength limit state loading given in the above table and based
on the design capacities provided by the manufacturer of the fixing.
