Ancon MDC Bracket Angle Support Systems (Patent No. 2 249 816) can carry over 8 metres of brickwork and accommodate any width of cavity from 40mm in its standard form. The brackets are welded to the angle and the material content of both components is optimised to ensure the most economic solution is designed.

There are several variations of the standard MDC System that allow the support angle to be positioned anywhere from the top of the bracket to a position below the bottom of the bracket.

Standard configuration

MDC/R has a reversed angle

MDC/I is an inverted system with the support angle at the top of the bracket

MDC/P has the bracket projecting below the structure

MDC/P/NB has a notched bracket

Soldier courses can be suspended from MDC systems by using stirrups at 225mm centres. The stirrups fit over the angle and stitching rods span between the stirrups, supporting cored or holed bricks.

Ancon can provide drawings showing the location of the fixings (cast-in channels for concrete frames, bolt positions for steel frames). Bracket angle units will be referenced and scheduled and all details submitted for approval before manufacture.

Ancon MDC Systems are tailored to suit each contract, and are based on the cavity size at the support and the masonry load to be carried. Ancon will design an economical configuration of channel, bracket and angle.

Specification is as follows:

e.g. MDC / R / 75 / 5.6
Ancon will design a system with a reversed angle to suit a 75mm cavity and carry 5.6 kN/metre run of masonry.

Some applications demand that the support leg is below the soffit of the structure. Where this is no more than 150mm, this can be specified as a suffix to the standard reference by . . . . . . P projection.

e.g. MDC / 125 / 7.2 / P 75
Ancon will design a standard system to suit a 125mm cavity, carry 7.2kN/m, with a bracket projection of 75mm.

Adjustment
Adjustment is provided in every direction to allow for tolerance in the structural frame. The serrated and slotted face of the bracket allows for vertical adjustment. Cast-in channel will provide virtually unlimited horizontal adjustment; slotted holes in a steel edge member will offer more limited adjustment. Shims can be included between the bracket and the frame up to a maximum thickness of the outside diameter of the fixing bolt, or 16mm, whichever is less. When used, the 3mm thickness of an Ancon Thermal Break should be taken into account when calculating the maximum shimming allowance for a system.

As an alternative to shims, Ancon Extension Plates can sometimes be used to increase the bearing for the brickwork.

Ancon Extension Plates are designed to be used with Ancon Support Systems. The particular application should be agreed with Ancon technical staff to ensure that both the support system and extension plates are suitable. Contact Ancon's Technical Services Team for more information.

These extension plates are pushed onto the leg of the angle with the flat surface on top. They are adjusted until the required amount of extension is achieved, this will be from 5mm to 17mm.
