The economical way of achieving a strong, rigid structure.Quick and easy to install with a nail-gun. More effective than skew or end nailing.
TYPICAL APPLICATIONS
Joining timber at right angles
For tie down to double top plates
Purlin
NOTE:
- Nail-Gun driven nails are to be more than 5mm from any metal edge or hole and spaced minimum 15mm apart.
- Gun-Nails are not to be driven at excessively high pressure, as they may punch through the steel product. Nail heads should be flush with the metal surface.
- Care must be taken when using Nail-Gun driven nails through metal products. Refer to the Nail-Gun supplier’s safety recommendations before operating these tools. Items to consider include safety clothing, eye protection and the angle of the nail to the metal should be 90°. Multinail does not accept any responsibility for injuries incurred, if Nail-guns are used for installing Multinail metal products.
TIE DOWN CAPACITY
| Joint Group | Tie down capacity (kN) per Uni Tie Dead Load + Wind Load |
|---|---|
| J2 | 4.0 |
| J3 | 3.1 |
| J4 | 2.2 |
| JD3 | 4.0 |
| JD4 | 3.1 |
| JD5 | 2.5 |
NOTE: The capacities are derived from testing in accordance with AS1720-2010 and are for uplift in houses where failure is unlikely to affect an area greater than 25m2. For primary elements in structures other than houses or elements in a house for which failure would be greater than 25m2 these capacities must be multiplied by 0.94. For primary joints in essential services or post disaster buildings multiply by 0.88. For 2/Uni Ties the table values can be doubled.
FIXING
4/gun-nails into each truss and 2/nails into each top plate
(4/nails in total to top plates or beams),
Note: All nails need to be 32mm long x 2.5Ø hardened screw shank nails and comply to AS2334-1980 or ASTM F1667-15.
Install the Uni Ties as shown to achieve twice the load in the Limit State Design Load table.
Nailing into both sides of a single 35mm truss is not recommended as it may cause the timber to split.
