Why use IG Masonry Support?

Masonry Support Systems provide a solution to the movement of brickwork due to factors such as moisture, thermal fluctuation, loading, ground movement and structure settlement.

HORIZONTAL MOVEMENT JOINTS

To cope with vertical movement in a masonry facade a compressible horizontal joint must be introduced at the required levels.

The underside of the shelf angle should be set 2.5mm above the level of the compressible filler to allow for any settlement that may occur as a result of the vertical dead load imposed by the masonry and to accommodate expansion of the brickwork below.

The minimum expansion gap should be at least 12mm where there is a single story height of brickwork below the support system. The gap should be increased by 1mm for every additional metre in panel height.

Wall ties should support no more than 300mm above and below the shelf angle.

STRESS FRACTURING

Masonry Support Systems provide a solution to issues such as stress fracturing and cracking to brickwork. Fracturing can occur as a result of excessive loading and expansion. Masonry Support Systems alleviate this problem.

FIXING TO STEEL – CORROSION RESISTANCE

The structural steel member must be designed to minimise deflections and accommodate the torsional forces created by eccentric loading from the brickwork.

IG Masonry Support Systems are manufactured from 304 austenitic stainless steel. Isolation-packing shims are installed between the IG Masonry Support bracket and the structural steel frame to prevent Bi-metallic corrosion.

Bi-metallic reaction is the corrosive effect which occurs when two dissimilar metals such as stainless steel and mild steel are in direct contact with each other in a damp environment.

IG Masonry Support Systems supplies isolation-packing shims as standard.

DIFFERENTIAL MOVEMENT

Differential movement is typically caused by settlement in the building frame in the opposite direction to potential expansion of the brick outer leaf which may be caused by thermal fluctuations and moisture absorption.

LIMITATION ON UNINTERRUPTED HEIGHT

When the method of limiting the uninterrupted height is adopted in accordance with BS 5628 : Part 1, the outer lead should be supported at intervals of not more than every third storey or every 9m, whichever is less. This method employs shelf angles and horizontal joints, which subsequently provides a means of vertical movement control. For buildings not exceeding four storeys or 12m in height, whichever is less, the outer lead may be uninterrupted for its full height. However masonry support s often incorporated in many buildings of less than four storeys or 12m.
