ANCHORS, CONNECTORS AND FASTENERS
Anchors, connectors, and fasteners require specialized manufacturing to meet today's stricter codes.
To avoid corrosion and maintain the long-term integrity of the exterior masonry wall, reinforcement and anchors need to be either hot-dip galvanized or stainless steel. Interior masonry walls can still use a mill-galvanized finish, but the trend in the industry is for all reinforcement to be a minimum of hot-dip galvanized to prevent confusion over the material type on the jobsite. The use of stainless materials is rapidly growing and strongly recommended for stone veneer applications. For wall reinforcement, truss type reinforcement is a stronger product, due to its greater effective steel area. However, the ladder type has become increasingly popular, because of its ability to handle more movement and deflection in the wall. More important, as more masonry walls incorporate vertical reinforcement, the design of the ladder type allows for the cores of the block to remain open, so as not to interfere with the placement of the vertical rebar. Wire diameters of nine-gauge or 3/16-inch are available for these applications.
Two major points to consider when selecting an anchoring system are the vertical adjustability factor and the potential for dis-engagement. Vertical adjustability describes how much flexibility an anchoring system can give the contractor to effectively place the anchor, so that the tie can line up with the veneer joint. This is especially important when using oversized veneer units, and even more so when combining different product types into a single veneer. Disengagement of the anchor through normal wall movement has become another hot topic, and many new products on the market today address this issue for both CMU and steel stud wall assemblies.
