Masonry support is typically a steel support structure for the brickwork façade of a building, fixed back to either cast in channel, concrete of the steel frame of the building (SSF).
Masonry support is used to reduce the load of the façade and distribute it through into the structure. This reduces chances of cracking and movement within the façade.
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, whichever is less, may be uninterrupted for its full height.
