AS/NZS 1577:2018 pdf free.Australian/New Zealand Standard Scaffold decking components.
1.4.4 Deck mull
A plank or prefabricated platform less than 220 mm wide used to complete a platform when planks or prefabricated platforms do not modulate to suit the width of a scaffold bay.
1.4.5 Decking component
A discrete component intcndcd to bc used to form a platform within a scaffold.
NOTE: Types of decking components include scaffold planks (either modular, or non-modular). lap plates, prefabricated platforms, filler plates or deck infills.
1.4.6 End joint
A glued joint between the ends of lamination segments or veneers.
1.4.7 Filler plate
A decking component that spans and covers a longitudinal gap between adjacent planks or
prefabricated platforms and that is supported by these components.
1.4.8 Laminated veneer lumber ([Nt)
An assembly of veneers laminated with adhesive, in which the grain direction of the outer veneers is in the longitudinal direction.
1.4.9 Lap plate
A decking component that spans and covers a gap between adjoining bays of a scaffold platform.
1.4.10 Modular plank
A scaffold plank of a predetermined length to suit a prefabricated modular or frame scaffold system, which is intended to be supported in such a way as to preclude both uplift and sliding longitudinally, and which may also incorporate additional secondary elements including end caps, hooks, flange straps, web stiffeners, etc.
1.4.11 Non-modular plank
A scaffold plank, other than a modular plank, intended to be simply supported and to overhang its end supports.
1.4.12 Prefabricated platform
A framed assembly of one bay length incorporating a working surface that is capable of connecting to its support structure in such a way so as not to be inadvertently dislodged.
NOTE: One or more platforms may be used to suit the bay width.
1.4.13 Scaffold plank
A decking component, other than a prefabricated platform. deck infill or lap plate. that is used or intended to be used to form a platform.
NOTE: Materials for scaffold planks include solid timber, laminated timber (including laminated veneer lumber), formed steel section, extruded aluminium section, etc.
1.4.14 SlidIng
The longitudinal movement of a scaffold plank relative to its supports.
1.4.15 Slip resistance
The effective coefficient of friction of the walking surface of a decking component such that a person is not at an unreasonable risk of slipping.
1.4.16 Spring
A longitudinal curvature of the edge of a timber scaffold plank not affecting the face. See Figure 1.1(c).AS/NZS 1577 pdf download.
