types of wall ties

Type 3 wall ties Z-Type and Rectangular Type Wire Ties. As a general rule, ACS recommend opting for either a type 2 or type 4 wall tie due to their increased compatibility and availability. Standard Specification for Zinc Coating (Hot-Dip) on Iron and Steel Hardware, ASTM A153-09. Standard Specification for Steel Sheet, Zinc-Coated Galvanized or Zinc-Iron Alloy-Coated Galvannealed by the Hot-Dip Process, ASTM A653-10. (356 mm) have been engineered. These wall tie analyses are becoming more common as a means to accommodate more thermal insualtion in the wall cavity. Type 4 Light Duty Wall Tie for buildings not greater than 10 metres in height for traditional brick/block construction DD140 Part 2: Recommendations for the design of wall ties DD140 Part 2 classifies ties according to their strength and function. Designed for use on domestic homes up to 10 meters in height. Standard Specification for Steel, Sheet, Cold-Rolled, Carbon, Structural, High-Strength Low-Alloy with Improved Formability, A1008-11. Type 2 wall ties can be used in cavities up to 100mm. Wire wall ties can be either one piece unit ties, adjustable two piece ties, joint reinforcement or prefabricated assemblies made up of joint reinforcement and adjustable ties (see Figure 2). Anchors connect masonry to a structural support or frame. The section that spans the cavity has a series of holes to provide water drips. Sat Nav: LS9 0DN. Two part ties (TPT) are a heavy duty wall tie which exceeds type 2 wall tie requirements BE EN 845-1 up to a 250mm cavity. Timber wall ties must meet type 5 requirements and BS5268-6.1 standards. However, there is currently no accepted computer program to address this point, so most designers still use the contributory area approach with a factor of safety of three. When it comes to wood-frame construction, hurricane ties are among the most commonly specified connectors. 5), wire anchors and ties—ASTM A82 (ref. This is especially significant as more insulation is used between the outer and inner wythes of cavity walls and where wythes of dissimilar materials are anchored together. These include unit ties, continuous horizontal joint reinforcement, adjustable ties (unit and continuous) and re-anchoring systems. Ancon fixings are manufactured from Austenitic stainless steel. Channel ties have a dovetail design which matches our channel perfectly whilst being compatible with other brands. Placement requirements for ties are shown in Figure 1. Empirical Design of Concrete Masonry Walls. These are incredibly easy to use and no special skills or tools are required for installation. Type 2 wall ties or general purpose wall ties, join together two masonry/blockwork leaves. Column wall ties are used to fix masonry to steelwork. The use of additional anchors near the edges of wall panels is also recommended and required around large openings and within 12 in. In this type, the whole tie member is a single unit and for holding this when placed in forms, special holding devices are used. Masonry connectors can be classified as wall ties, anchors or fasteners. Channel ties work in conjunction with ACS Axis channel, cast in channel and frame fix channel. Reported by the Masonry Standards Joint Committee, 2011. 27 for a discussion of potential masonry wall movements). The prescribed size and spacing is presumed to provide connections that will be adequate for the loading conditions covered by the code. 25) for more information. Anchors are usually designed based on their contributory area. WTF's innovative design, long lasting products, ease of setup and speed of construction assure that you won't be confined by inferior or restrictive products. There is no specific criteria on connector stiffness, but some authorities suggest that a stiffness of 2,000 lb/in. Note that truss-type joint reinforcement is stiffer in the plane of a wall compared to ladder-type, so it is more restrictive of differential movement. ASTM International, 2006. Ties would be selected by type of masonry, the cavity width, and so on. They play a critical role in a structure’s continuous load path and may be used in a variety of applications, like attaching roof framing members to the supporting wall top plate(s), or tying wall top or bottom plates to the studs. Transmit out-of-plane loads from one wythe of masonry to another or from masonry to its lateral support with a minimum amount of deformation. (114 mm) without performing wall tie analysis. Standard Specification for Epoxy-Coated Steel Wire and Welded Wire Fabric for Reinforcement, ASTM A884-06. plate and bent-bar anchors—ASTM A36 (ref. Porcelain Tile. the span length of the pintel component typically controls the mode of failure. ASTM International, 2011. See TEK 12-2B (ref. Fasteners connect an appliance to masonry. The primary differences between these wall systems are in construction details and how the applied loads are assumed to be distributed.
