Formwork Components & Terminologies Building Codes & Rules

Falsework

Shuttering Board^Informative

• Rough grade Plyboard used as moulds for poured Concrete

U-Head / Forkhead^Informative

• Fixed or adjustable types
• Used to hold timber or steel beams securely in place

Clamps / Couplers^Informative

• Used to securely attach formwork elements together
• Prevents any formwork movement or shifting

Base Jack^Informative

• Enables accurate levelling on uneven & sloping ground
• Designed to prevent rotation & excessive settlement

Secondary Beam / Joist

• ≤ 400mm CTS^{Manufacturer's Recommendation}
• Horizontal members distributed on top of bearers^Informative

Formwork

Horizontal Brace^Informative

• For lateral stability & alignment

Diagonal Brace^Informative

• Corner-to-corner cross-bracing for resistance to lateral forces
• Lessens risk for swaying & deformation

Primary Beam / Bearer^Informative

• Main horizontal support
• Timber or Metal

Formwork^Informative

• Temporary support system for wet concrete until it cures
• Ensures that concrete takes on the desired shape & dimensions
• Comprised of the mould or cast & its supporting components

Sideform / Edgeboard^Informative

• Perimeter framing
• Robust & reusable formwork

Vertical Props^Informative

• Supports a horizontal formwork system
• Assembled together with bracing frames, to serve as load-bearing support

Inspection & Certification^Informative

• Comply with AS 3610.1, Formwork for Concrete
• Pre-loading Inspection & Certification
• Formwork Structural Certificate, issued by a Certifying Engineer as guarantee that installed formwork meets design specifications
• Inspected when formwork is complete, before concrete is poured
• Pre-stripping & Dismantling Certification
• Sign-off required from Structural Engineer that the permanent structure has achieved self-support, prior to stripping

Falsework^Informative

• Part of the formwork assembly
• Temporary structure used to support the forms for concrete, until it gains sufficient strength
• May also serve as access and support for materials, equipment, & people during construction
• Comprised of Beams, Posts, adjustable props, Scaffolding, & connectors

Design of Structure^Informative

• All formwork drawings to be certified as compliant to applicable standards
• Consult an experienced formwork designer for the design, including assembly & dismantling
• Document temporary work platforms & equipment required for safe on-site installation
• Documentation to include a statement of all expected loading & dimensional changes
