Rod Tie Down Plate – LVL

The Rod Tie Down Plate is an alternative tie-down method for locations requiring M12 threaded rods, such as LVL lintels or ring beams, as specified in Table 9.20 of AS1684.2 and AS1684.3.

It is challenging and error-prone to drill a vertical hole through a deep ring beam which can exceed 400 mm in depth. Misaligned threaded rods may exit from the side of the beam instead of the bottom, rendering tie-down connections ineffective. Replacing or repairing damaged beams results in additional costs and delays. The Rod Tie Down Plate - LVL eliminates the need for deep drilling by using screws, addressing this on-site challenge.

The Rod Tie Down Plate - LVL satisfies NCC Performance Requirement P2.1.1 by adhering to the design rules in Australian standards AS1720.1, AS1684.2, AS1684.3, and AS1684.4. Extensive testing with LVL from various local suppliers confirms that its tie-down capacity exceeds the requirements specified in Table 9.20 of AS1684.2 and AS1684.3 for M12 threaded rods.

• Minimum beam width: 63mm.
• Minimum 250mm end distance. 
• Design engineers must verify the timber beam’s capacity to achieve the required uplift strength.

Yes, Rod Tie Down Plate can be used singly to transfer the uplifting force to a beam.

Yes, Rod Tie Down Plate - LVL can be used with offsets, provided the timber beam is structurally sound. An offset pair of Rod Tie Down Plates will create an additional bending moment on the timber beam, which requires structural engineer approval.

No, all screws in Rod Tie Down Plate series must be pre-drilled according to the installation guide due to the close spacing on narrow beam edges.

The unthreaded section of the screw is 80 mm in length. This is critical to understand as it represents the maximum allowable thickness for all the material between the screw head and the edge of the ring beam. Here is an example of what is allowed: Rod Tie Down Plate (6 mm) + flooring (25 mm ply) + bottom plate (45 mm) = 76 mm. This is within 80 mm; therefore, it is acceptable.

The threaded section of the screw is 70 mm in length.

No, the threaded section of the screw must be fully embedded in the LVL beam only. This ensures that the flooring and the top and bottom plates are not affected by the uplifting force and that their structural integrity is maintained.

Multinail Locknail plates are essential for reinforcing the connection when using LVL beams. They prevent premature failure of the LVL beams by providing additional strength. Locknail plates are installed on-site with a hammer at the designated locations.

No. Only Multinail Advance Panhead screws provided in the kit are certified for use. Using alternative screws will invalidate the certification.

They are supplied in kit boxes containing all necessary components. The detailed kit contents are listed in the product brochure.

No. Rod Tie Down Plate - LVL can only be used with LVL beams. There is a Rod Tie Down Plate - GLT available for GLT beams with modifications to the brackets and the kits. Other engineered wood products are not supported.
