01.030.0705 Shelf Angle | Anchored Brick Veneer, CMU Backing, Shelf Angle w/ Bracket-Type Standoff

International Masonry Institute
Description
This detail illustrates a shelf angle projected from the concrete masonry backing with a system of standoff brackets anchored to the backing. The use of these brackets allow the shelf angle to not be in contact with the backing, which would otherwise tranfer heat across the cavity. The brackets project the shelf angle out the required distance to adequately support the brick veneer, and insulation is allowed to run in between and behind the brackets. SPF insulation is shown to fill the interstitial space around the brackets. A horizontal expansion joint below the shelf angle allows for vertical expansion of the brick veneer. The detail also incorporates a vertical brick expansion joint, and a vertical control joint at the block backing. The flashing protects the shelf angle, and weep vents allow moisture to exit the wall. A drip edge protects the steel angle and ensures water does not travel back into the wall beneath the flashing.
