Ties for Steel Frames

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 rigid insulation board, 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.

25/14 channel is supplied in lengths of 2700mm and 3000mm, 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. Screws are available to accommodate a combined backing board and insulation thickness of up to 220mm and a steel thickness from 1.2mm to 3mm. See technical literature for screw references and vertical fixing centres. Also suitable for use with timber frames, contact Ancon for details.

The channel has a 16mm opening to easily accommodate a drive socket and washer for the fixing screws. This system has been independently tested.

Ancon recommends SD25 wall ties achieve a minimum embedment of 55mm in the outer leaf of brickwork. They are available in lengths from 100mm to 300mm to suit open cavities up to 259mm.
