StoneClip vertical panel fix system certified by Sheehy & Partners
This is to certify that Sheehy & Partners have checked the design of
the mechanical fixing known as "StoneClip." The StoneClip parameters and design capacities
are summarised below. This limit state loading on the fixings to connect the StoneClip to the
substrate are also provided.
Design Assumptions
The design has been based on the following;
- StoneClip 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 StoneClip'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."
StoneClip Geometry
StoneClip Design Capacity Tables
1.0 Vertical Loading Only;
The following tables are for StoneClip's carrying a vertical loading only (no allowance for wind loading).
Each StoneClip is fixed with one fixing through the top hole in the back plate. Fixings are to be selected
with accordance with fixing manufacturer's documentation.
* Limit state load.
# "Cavity" is the distance between the substrate and the inside face of the panel.
2.0 Lateral Loading Only;
The following tables is for StoneClip's carrying lateral loading only (no allowance for vertical loading).
Each StoneClip is fixed with two fixings through holes on opposite sides of the centre. Fixings are to be
selected in accordance with fixing manufacturer's documentation.
^ The wind area is the maximum area that one StoneClip can resist based on the design wind pressure of
2.53 kPa, 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.
Certification
If the StoneClip installation is completed in accordance with the above design, the StoneClip.com specifications
and sound building practice, the "StoneClip" mechanical fixing is considered to be structurally adequate.
This certificate does not cover the strength of the stone panel or the transfer of load from the stone panel to
the "StoneClip."
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 tables and based
on the design capacities provided by the manufacturer of the fixing.
