Tectonic Headtrack
Description

The Tectonic Headtrack allows for the top of full-height walls to meet multiple performance criteria. It deals with inter-storey drift and vertical deflection between two structures effectively while not conceding acoustic and fire performance.

Slots in the vertical and horizontal plane of the head track are designed to allow for building deflection and inter-floor movement caused by seismic activity and dead/live loading. Wall junction details have been developed and tested to reduce damage to the wall due to seismic and building drift.

  • The Tectonic Headtrack is manufactured in New Zealand from 250MPa, hot dipped galvanised mild steel. 
    Standard length 2970mm
    Total depth 91mm
    Recess depth 30mm
    Gauge 1.2mm
Key Features
  • The Tectonic Headtrack allows for movement along multiple axes. The slots in the top of the headtrack allow for horizontal deflection (relative horizontal movement between storeys in an earthquake) and the vertical slots allow for vertical deflection between storeys due to dead/live loading as well as earthquake deflection).  The system has been tested on a Shake Table.
  • The Tectonic Headtrack has been fire tested according to AS 1530.4-2014 Methods for Fire Test on Building Materials
  • Sound intensity measurement showed that on a STC 52 wall there was no reduction in the overall acoustic performance of the partition.
  • The Tectonic Head Track is easily integrated into either timber or steel 92 mm wall framing constructions.

Other Performance Attributes

Acoustic: 

An acoustic assessment was carried out on a wall system with a Tectonic Headtrack to evaluate the performance in a partition system. A high-density passive fire protection strip was fitted to both sides of the track in the specially designed recess. Sound intensity measurement showed that on a STC 52 wall there was no reduction in the overall acoustic performance of the partition. Where a fire rating is not required, a high mass filler strip can also be used, of between 4 – 5 kg m². Test report available on request.

Fire testing: 

The Tectonic Headtrack is defined as a control joint, therefore, when it is used in a fire rated system, the correct passive fire protecting must be employed. Tectonic Headtrack has been fire tested to with AS 1530.4-2014 Methods for Fire Test on Building Materials. Although the detailing is up to the fire engineer, we recommend two passive fire protection systems: RyanFire Batt 502 and RyanFire Graphite Strap.
