Masonry: Masonry Ties

I'd like to look at brick ties or masonry ties in this short video. We have the CMU and then we looked earlier at a truss tie and a ladder tie that are in the bed joint of the CMU and typically they are placed every three layers of CMU, so here and here, but it looks like that's a minimum. So in this case, they've put them every two layers, and there is vertical reinforcing in the CMU, and it's grouted, and that vertical reinforcing is placed every 32 inches, maybe. So that's every other CMU block. The CMU block is 8 inches by 16 inches. So that's a module that we use for measuring where to place the horizontal and vertical reinforcing. So then they will paint that wall with some kind of insulation or sorry with some kind of waterproofing by two minutes layer then they will put rigid insulation typically between the eye hooks that were in the truss bar truss and ladder reinforcing and then they will attach the brick with these hooks so there's different varieties of hooks but the eyelets that are sticking out are usually they are hooked and The brick, the mortar joint of the brick is going to have these hooks, and then they attach them to the backup wall. And here are the hooks, we see them very clearly. There's many varieties of attachment. Here's a corrugated galvanized attachment. All of these are galvanized, but basically you can bend it until it falls at the correct coursing, so it corresponds with the correct coursing of the brick. And some of these are adjustable so that depending on where you are with the coursing, you can lay these galvanized pieces in that mortar joint.
