Masonry Support

ACS provides a wide range of brickwork support & masonry support systems designed to support the external leaf of masonry for all types of structure. The presence of a masonry support angle allows differential movement of the structure and the external cladding via a horizontal movement joint.

Horizontal movement joints are usually positioned at every storey or every other storey depending on the detail. However, the maximum allowable height of masonry to be supported is 9m or 3 storeys in height – whichever is less (refer to BS 5628: Part 1 – 1992).

Note: Buildings not exceeding four storeys or 12 metres in height, which ever is less, may be uninterrupted for its full height.

Materials

ACS brick and masonry support systems are generally manufactured from stainless steel Grade 304 material; however, we can manufacture systems from Grade 316 stainless steel, especially if it is to be used in corrosive environments such as coastal areas.

Where stainless steel comes into contact with mild steel it is important to isolate the dissimilar materials via neoprene spacers to prevent bi-metallic corrosion. These are available from ACS.

Adjustments/ Tolerances

ACS masonry support systems may be adjusted in 3 directions depending on the fixing detail to overcome site tolerances.

Vertical adjustment

This can be accommodated via the use of alpha or serrated washers over vertical slots in the system.

Longitudinal adjustment

This can be accommodated via horizontal slots in steelwork or via a continuous cast in channel.

Lateral adjustment

This can be accommodated via stainless steel shims. The maximum allowable shim is the thickness of the bolt or 12mm whichever is less. If shimming exceeds this figure please liase with the technical department.

Alpha Bracket System

Almost every brickwork support system designed and manufactured by ACS now incorporates the new Alpha Bracket.

The Alpha Bracket has been developed to replace the traditional serrated bracket and offers many advantages including the following:bracket

Lock Safe : Where a serrated pad and washer fails, the positive locking Alpha Bracket locks in on itself preventing catastrophic failure.

Finer Adjustment : The Alpha Bracket has over 5mm more vertical adjustment than a traditional serrated bracket system; in addition to this the Alpha Washer allows 4mm fixing increments.

 

Economic : Because much greater loads can be achieved, in most cases fewer brackets need to be used. On a typical system we estimate this could save over 10%.

The Alpha Bracket has been independently tested at Sheffield University and has been proven to perform on average over 20% better in shear than the traditional serrated bracket system.
