Ties for Steel Frames
Ancon 25/14 Restraint System
The Ancon 25/14 channel system is designed to tie brickwork to steel frames including steel studwork. Self-drilling screws fix through the channel and the insulation material, into the steel. Once the channel is installed, Ancon SD25 wall ties can be positioned at any point along its length and are built into the bed joints of the outer leaf of brickwork. The spacing of ties is based on the height of the building and its geographical location.
25/14 channel is supplied in lengths of 2700mm and features pre-punched holes at close centres to ensure a fixing position is always located near the end, even when it is cut on site. It should be fixed to steel studwork at 450mm vertical centres. Screws are available to accommodate an insulation thickness of up to 114mm and a steel thickness from 1.2mm to 3mm. Ancon recommends the use of stainless steel fixing screws but other screws are available.
The channel has a 16mm opening to easily accommodate a drive socket and washer for the fixing screws. This system has been independently tested.
