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. Following the guidance of PD6697, vertical joints not less than 10 mm wide to accommodate horizontal movement should be provided at intervals of between 7.5 m and 9 m.

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 II Bracket System

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

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

Lock Safe: Improve safety and prevent catastrophic failure with the patented positive locking feature. Inferior serrated systems cannot compete as the Alpha II Washer engages the brackets teeth with greater ease locking itself on, establishing a new standard in safety.

Economic: Save money and installation time, as fewer brackets are required per project thanks to the increased load strength.

Installation: Speed up construction and slash installation costs as the Alpha II’s extra wide aperture allows all current fixing configurations to pass through the front of the bracket with ease.

Finer Adjustment: Achieve even the tightest of tolerances, removing the need for complex and costly site based solutions thanks to the improved finer adjustment of Alpha II.

The Alpha II 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.
