Fixed to the top plate of non-bearing bracing walls to transfer racking loads from ceiling plane
Pryda Shear Connector are used in pairs to transfer racking loads from the ceiling diaphragm to non-load bearing internal bracing walls.
These connectors allow vertical movement of the trusses (to release creep deflection) and ensures that the truss camber dissipation is uninhibited by over-driven nails.
Fixed to top of bracing walls, Pryda Shear Connectors can be used as a direct substitute for a pair of nail fixed timber blocks as specified in Table 8.22 AS 1684.2:2010 and AS1684.3:2010 of the Pryda Bracing Design Guide.
Pryda Shear Connectors have better capacities, and are easier and quicker to install than timber blocks and alternate brackets.
They can be installed with collated nails, versus hand driven nails only for alternate brackets – it is difficult to nail into the corner holes within alternate brackets.
It is quicker to fit 2 Shear Connectors than trying to locate alternate brackets into position, especially if the timber is over sized or has swollen with moisture.
Accommodates all timber widths, including double trusses, whereas alternate brackets only work with 35mm timber.
Long term performance is not affected should the nails have been over driven. Alternate brackets will not work if the nails have been over driven which also means there is a likelihood of a fabricator and/or builder call back.
To install Shear Connectors:
- All trusses are to be installed in accordance with the requirements of AS4440.
- Discard any damaged product.
- It is preferable (but not essential) to fix the Shear Connectors after the roof cladding has been fixed and prior to the application of the ceiling material.
- The Shear Connectors are to be installed in opposing pairs on the same bottom chord of a truss.
- Ensure the connectors are located adjacent to each other and directly over the internal, non-load bearing bracing wall to which they are to be fixed.
- Fix each connector to the truss bottom chord with the specified number of nails so that the connector is flush up against the vertical face and under side of the truss bottom chord.
- Ensure the long leg of each connector passes under the bottom chord and is located directly over the underlying top plate.
- Press vertically downwards on the free end of the long leg of the connector until it contacts the top face of the underlying top plate.
- Fix the long leg down to the underlying top plate with the specified number of nails.
- Repeat where marked on truss & wall frame layout.
