Platinum Building Chemicals Ltd | Wall Ties
Brass Wall Ties are designed to replace or supplement existing cavity wall ties.
Available in 2 sizes, 200mm and 225mm lengths.
The Brass Wall Tie sets new standards in replacement wall ties.
The Brass Wall Ties' unique design concept creates a tie which provides maximum anchoring strength over a far greater surface area than the traditional ‘point loading’ anchoring system currently used in other replacement wall ties.
The design of the Wall Tie ensures the fixing sleeve expands along its full radial length to provide an extremely strong uniform fix over the entire surface area of the sleeve anchor giving a substantially improved and more reliable ‘fix’ than the traditional sleeve which, because of its design limitations, only achieves a ‘point loading’ fix over a relatively small part of its surface area.
Suitable for all wall tie replacement applications save for use in perforated bricks or in friable blocks having a compressive strength of less than 7N/mm² (Ref: BRE Digest 329 Decision Tree).
Using an 11mm drill bit and inclining the drill slightly upwards, drill a hole through the brick of the outer leaf until you reach the cavity.
With the tip of the drill touching the inner leaf set the depth gauge to 70mm.
Drill into the inner leaf (if the inner leaf is blockwork the drill’s hammer action should be turned off).
Ensure all dust is removed from bore hole using an airline or air pump.
Using a cordless drill, put the Setting Tool into the chuck and set the clutch / torque to ¾ strength. Place the tie end into the Setting Tool. Start drilling at medium speed.
Push the tie to the back of the drilled hole, making sure there is 'friction' when the tie passes through the outer leaf - if not, pre-expand the tie first.
When clutch operates, the tie is set.
10mm - 11mm into normal brick and blockwork.
10mm - 11mm into outer leaf only if Stock or Accrington brick.
