Brickwork Restraints, Parapet Channels & Compound Sections
Hi-Span C-Channels can be used to restrain small block/brickwork walls. The channels sit directly on top of the wall and are connected using sliding anchors. The wall will proved support to the channels about its weak axis, and the channel will restrain the wall against horizontal wind forces. Where walls are erected after the channels, temporary propping will be needed until the wall is in place.
When designing brickwork restraints using the Hi-Span Design Suite, consideration must be made to the higher deflection limits required by both block and brickwork walls.
Restraint must be provided to the outer flange of the channel by a positive fixing to the overlapping cladding.
