Movement ties are an important feature in masonry construction as they allow walls to be tied to other structures, such as steelwork of masonry, while providing restraint in one direction but allowing movement in the other. This is achieved by placing a debonding sleeve over the part of the tie which is to be embedded in the wall. Movement ties are also used in movement joints that span long stretches of brickwork, spanning across vertical joints to hinder any vertical movement while enabling horizontal expansion and contraction.
The purpose of movement ties is to ensure the structural integrity and safety of the building by allowing for some movement while preventing dangerous movement that could cause damage, such as cracking and warping of building materials.
At Vista we offer five options, the SPE/B20 Safety Plain End Tie/Blank, the SPF Safety Plain End Tie/Blank, the V7PE Plain End Frame Cramp, the V8PE Dovetail Plain End Tie and the V63PE Plain End Clasp Tie. Each ties serves a specific purpose and application:
Used over a movement joint in a run of brickwork or blockwork with safety embedment detail or plain end (B20). (Sleeve supplied as extra).
The SPF is a lighter, stronger evolution of our SPE. Used over a movement joint in a run of brickwork or blockwork with safety embedment detail. (Sleeve supplied as extra)
Used for restraining masonry to steelwork whilst allowing lateral movement. (Sleeve supplied as extra).
This product allows lateral movement between masonry and a fixed channel or slot. (Sleeve supplied as extra).
Used for side fixing a steel column to masonry whilst allowing lateral movement. (Sleeve supplied as extra).
In addition to the ties themselves, Vista also offers debonding sleeves (V36) that allow for movement of the ties listed above (a 25mm wide sleeve is required for channel ties). Debonding sleeves should have a 10mm gap left at end to allow for movement once installed.
All of these ties are manufactured in the UK from grade 304 stainless steel and are designed to be easy to install. They are also durable and long-lasting, which means they provide excellent value for money.
If you are unsure which of our four movement ties you need then please call the office who can discuss your requirements.
