AS 1576.6:2020 pdf download.Scaffolding Part 6: Metal tube-and-coupler scaffolding – Deemed to conform to AS/NZS 1576.1.
2.1 Tubes
2.1.1 Steeltubes
Steel tubes shall —
(a) be manufactured by the electric resistance weld process (ERW);
(b) have a minimum yield strength of 250 MPa and shall conform to AS/NZS 1163;
(c) have a nominal outside diameter of 48.3 mm; and
(d) have a nominal wall thickness of 4.0 mm (a galvanized tube with a nominal wall thickness of 3.2 mm may be used).
2.1.2 Aluminium tubes
Aluminium tubes shall have —
(a) a minimum yield strength of 240 MPa;
(b) a nominal outside diameter of 48.4 mm; and
(c) a nominal wall thickness of 4.47 mm.
2.1.3 Mixing of tubes
Steel tubes and aluminium tubes shall not be mixed in the one scaffold, except for guardrails, midrails or other members that have an independent structural function.
NOTE For example, standards support load in conjunction with other standards and with spur braces, so groups of these elements should be of the same material. A jointed vertical standard assembly will accumulate load down a load path; so the material should be consistent throughout to ensure predictable structural action, unless specific engineering design has been applied.
2.2 Couplers and accessories
Couplers and accessories shall be in accordance with AS/NZS 1576.2.
2.3 Scaffold planks
Scaffold planks shall be in accordance with AS/NZS 1577.
2.4 Soleplates
On surfaces such as compacted soil or gravel, soleplates shall be —
(a) positioned under the baseplates; and
(b) large enough and configured so that sufficient bearing area is created to spread the load from the baseplate to the supporting surface to prevent subsidence or damage to that surface.
NOTE Timber scaffold planks used as soleplates should not include excessive longitudinal splits.
3.1 Standards
Standards shall —
(a) be founded on baseplates;
(b) be vertical;
(c) extend to the full height of the scaffold;
(d) be spaced as specified in Table 3.1
(e) be joined with end-to-end couplers; and
(f) not have joints that occur —
(i) in longitudinally or transversely adjacent standards in the same lift;
(ii) in the same standard in adjacent lifts;
(iii) more than once between adjacent ledgers; or
(iv) more than 300 mm from a ledger.AS 1576.6 pdf download.
