brick veneer anchor spacing

The Slotted Stud Tie (Type I) was developed for brick veneer steel stud wall construction where significant differential movement between the veneer and the steel stud backup wall is expected, such as high walls or multi-story buildings with full height veneer. horizontally and 25 in. shall be specified." Brick veneer might or might not have wall ties. C 1088: Specification for Thin Veneer Brick Units Made from Clay or Shale C 1261: Specification for Firebox Brick for Residential Fireplaces C 1298: Guide for Design and Construction of Brick Liners for Industrial Chimneys C 1405: Specification for Glazed Brick (Single Fired, Solid Brick Units) BRICK (Cont.) This engineering letter (L-C-BVLZPRESC19) includes all of the prescriptive spacing tables and images shown below in a … Similarly, the maximum wall area per anchor for all other veneer anchors is reduced to 2.45 square feet. Advantages: PRO-SLOT™ and Dovetail Anchor provide a permanent, fast, flexible and cost effective method of anchoring brick, stone and block veneer to poured concrete walls and columns. Example: Brick veneer is generally about 3-1/2 inches thick and has a 1 inch air space behind it so, if the embedment depth from the Anchor Chart in the engineering calls for 2 inches, the formula is: 3-1/2" brick + 1" air space + 1/2" sheathing + 2" embedment = 7 inches. Anchored brick veneer with steel stud backing consists of a nominal 3 or 4 in. may need to be reviewed as well as veneer anchors and coping design. The additional requirements in high wind areas are to space anchors at a maximum spacing horizontally and vertically of 18 inches on center as long as they meet the reduced maximum area requirements. All other anchors are spaced one anchor each 3.5 ft². Adding an additional 10 lb/ft for the angle weight results in R = 2460 lb. If the installer decides to always increase the anchor spacing or leave out anchors when the spacing geometry is interrupted, the consequence may be an inadequate number of veneer anchors. As an example, a 10-foot height of 4-inch clay brick veneer and an anchor spacing of 6 feet would produce a loading of R = 40 psf x 10′ x 6′ = 2400 lb. Maximum spacing is 32 in. (76 to 102 mm) thick exterior brick wythe mechanically attached to a steel stud backing system with corrosion-resistant metal anchors so as to create a prescribed air space between the veneer and the backing For designing a code-compliant, prescriptive residential wood deck, these tables list maximum on-center spacing for the BVLZ brick veneer ledger connector. If they do have ties, you don't know their spacing, if they'll actually be installed in field with that spacing, or their capacity. Spacing Adjustable anchors, 9-gauge wire anchors and 22-gauge corrugated sheet metal anchors require one anchor for each 2.67 ft² of wall space. I don't allow anchoring to brick veneer only; it's too much liability. 2. Dovetail Anchors are manufactured in 16 gauge hot dipped, galvanized steel and are furnished in 3 1/2” and 5 1/2” lengths with a 1” overall width. vertically, not … If there is a horizontal shelf angle at every floor with a control joint, the space between the underside of the angle and the top of the brick veneer must be large enough to allow the brick to expand and the frame to shorten. (3/16” max for a 3/8” joint) Anchors in the veneer must be embedded in the mortar joint a minimum of 1-1/2” in from the airspace and no closer than 5/8” from the veneer exterior. The designer can reduce interpretation in the field by limiting anchor spacing by the number of brick courses vertically or head joints horizontally. C 75: Sampling Aggregates Joint Thickness and Anchor Placement in Veneers: The mortar joint should be twice the thickness of the embedded anchor. Code required placement of anchor in veneer I always anchor to the structure. Section 6.2.2.6.3 of the MSJC code and BIA Technical Note 44B, Wall Ties for Brick Masonry state that "when corrugated sheet metal anchors are used, a maximum distance between the inside face of the veneer and outside face of the solid sheathing of 1 in. If there is not sufficient space, then
