GA/SB stone support brackets

 

G.A. offer a range of stone support brackets to suit most applications.

Wherever possible the recommendations in BS8298:1994 “Code of Practice for the Design and Installation of Natural Stone Cladding and Lining” are used as the basis for our design.

The document discusses recommendations on all aspects of natural stone support ranging from materials to fixing positions and required bearings.

In the case of cast stone units the fixing options are increased as cast-in fixings may also be considered.


Adjustment

The use of welded serrated pads and punched vertical slot on both the angle and system type brackets offers up to +/- 30mm vertical adjustment.

Specifying

To specify G.A. Stone Support Brackets follow the code as shown.
Note:- Cavity will determine whether angle or system is used. Brackets can be supplied with a plain horizontal slot if required.

Example shows stone support bracket fixed back to concrete using an M.D. Anchor.

The use of a SB1 type bracket with overbent angle ensures that the base of the stone unit is both
supported and restrained with additional ties only required at the head of the unit.

   

Example shows SB5 support bracket fixed back to concrete using a M12 M.D. Anchor. The stone unit is both supported and restrained by the dowel with additional ties only required at the head of the unit.

The soffit stone is suspended using GAC1 restraint ties fixed back to concrete via 28/15 cast-in channel.
