AS 2699.1 pdf download.Built-in components for masonry construction
This Standard specifies requirements for wall ties for use in tying together — (a) the leaves of cavity masonry walls; (b) masonry veneer walls and loadbearing frames; and (c) masonry veneer walls against a strong backing wall. This Standard applies to wall ties used in masonry described in AS 3700, AS 4773.1, and AS 4773.2, including those used in thin-jointed masonry [for example, autoclaved aerated concrete (AAC) blockwork]. NOTE 1 Type B wall ties are not used in this Standard. For Type B wall ties, refer to AS/NZS 2699.1:2000, which provides definitions, embedment, movement and tolerance requirements, marking, and methods of testing. NOTE 2 AS 2699.2 specifies the durability performance and test procedures for structural performance of connectors and accessories used in masonry construction. NOTE 3 AS 2699.3 specifies the requirements for durability of lintels and shelf angles. NOTE 4 This Standard gives categories of wall ties, and classifies wall ties by mean strength and durability. NOTE 5 The durability classifications employed in this Standard are compatible with the environments specified in ISO 9223, AS 4312—2008, AS 3700, AS 4773.1 and AS 4773.2. NOTE 6 Design and installation of wall ties are specified in AS 3700 and AS 4773.1 (design) and AS 4773.2 (construction).
