NZS4210, NZS4230 & AS/NZS2699
Tie selection is based on variables including tie type, expected loading (seismic and wind), veneer weight and exposure.
Requirements for different wall tie types are given in AS/NZS2699.1, NZS4210 and the related NZS3604, NZS4229 and NZS4230 present schedules for different veneer types, weights and situations.
These schedules should be read in light of recent changes in the requirements of the loading code AS/NZS1102.
Typically ties should not be spaced at more than 600mm horizontal x 400mm vertical centres. Ties should be long enough to extend at least half way into the veneer.
