Ties for Steelwork
A range of innovative solutions to tie masonry to steelwork without site drilling is available. Each fixing either abuts the steel or attaches to the flange to restrain masonry walls against lateral wind loads.
Simply hammered onto the flange, this fixing can be utilised either on a column with a tie (HOS-TIE) or on a beam with an internal head restraint (IHR-H). The Hammer-On fixing resists load in one direction only and should be installed on alternate sides of the flange. Ties should be installed at 225mm vertical centres and head restraints at 450mm horizontal centres.
|95mm, 155mm, 215mm|
|XS to suit 6.8-10mm flanges|
|S to suit 10-13mm flanges|
|M to suit 14-17mm flanges|
|L to suit 18-21mm flanges|
|XL to suit 22-25mm flanges|
Hammer-on IHR-H Head Restraint
Ancon Head Restraints provide the necessary restraint to the top of masonry walls. They allow for vertical movement to accommodate shrinkage or thermal movement of the wall or structural frame, while restraining wind loads.
The standard IHR will suit a 215mm block; other sizes between 150-250mm are available.

Standard length: 120mm
Supplied with a Debonding Sleeve
Internal Column Tie
Available in seven sizes to suit standard universal column/beam dimensions, this tie fits between the flanges of a column and should be installed at 225mm vertical centres.
|179mm, 186mm, 224mm, 232mm, 275mm, 281mm, 330mm|
Non-Standard Internal Column Tie
Special internal column ties can be designed to suit applications where the masonry does not sit inside the flanges of a column.
The Briclok fits to a column flange and can be used either across a cavity or back into the inner leaf. It should be positioned with the appropriate notch around the flange and installed at 225mm vertical centres. The tie must not be forced onto the column and should have no less than 10mm engagement.
Briclok A, for flanges from 6.8mm to 13.5mm
Briclok B, for flanges from 13.5mm to 20mm

Clamp-On Column Tie
The Column Tie clamps to the flange of a column. It accommodates a steel thickness from 6mm to 25mm and should be installed at 225mm vertical centres. Manufactured in lengths to suit the application, it can feature a drip for use across the cavity or a plain shank for installation back into the inner leaf. As standard, the clamp-on column tie is supplied right-handed as shown in the isometric product drawing below, but can be manufactured left-handed on request.

We are delighted to announce that we will be sponsoring a Bear for the 2021 ‘Bears of Sheffield’ sculpture trail, a unique participative public art event that will raise funds for a new, urgently needed, Cancer and Leukaemia ward at Sheffield Children’s Hospital.
Designed to minimise thermal bridging in masonry cavity walls, the patented Ancon Thermal Windpost (TWP2) from Leviat offers up to an impressive 70% reduction in thermal transmission through the span of the windpost.
